Technical Field
The present invention relates to a connector assembly, a liftable connector assembly employing the connector assembly, a method for coupling a modular support unit having the connector assembly, a method for assembling a modular unit having the connector assembly, and a building having the connector assembly.
Background
Prefabricated modular building units constructed from standard components in a controlled factory setting are desirable due to the reduced cost and improved quality that can be achieved compared to performing similar operations on an outdoor building site.
Accordingly, prefabricated modular building units having floors, walls and superstructure and containing all pre-installed systems and equipment within the interior are preferred and known in the art. Building assembly systems including means and methods for joining two or more modular building units together to form a larger structure are also well known in the art.
Means for engaging specially prepared holes on the upper or side surfaces of a structural frame to provide a releasable connection to lift and move modular building units are well known in the art.
A limitation of the construction of slim or high-rise buildings with factory-fabricated modules is that economically constructed modules cannot resist and transmit the torque and tension forces caused by wind and seismic forces and the large compressive loads caused by the gravitational effects of the building and occupants. Furthermore, all of these force types are exaggerated by the narrowing of one or both axes of the building. These effects are greatest in the lower floors and grow in proportion to the increase in height and slenderness, so the forces are also greatest at the lower floors. Many modular structural systems are characterized by pinned features of connection between adjacent modules and the lack of diagonal support beyond what is required for integrity during transport can limit the effectiveness of force transmission through larger assemblies of conventional module types.
The state of the art for constructing tall or elongated buildings from modules as taught by the technology cited herein is to maintain economies of scale of manufacture by reinforcing the integrity of all the modules making up the building so that all resist the forces in a distributed manner, as with large numbers of marine shipping containers; or with large columns positioned inside or outside the walls of all modules, forming alternative load paths; or constructing an adjoining or interconnected support frame that bypasses the modules and transfers large loads through the secondary structure to the ground; or with tie rods or cables that pass vertically through the building to anchor the modules in a manner that resists lifting and lateral shifting. All of the above solutions may have limitations in terms of achievable resistance to forces and transmission of forces, or require the installation of additional structures, which in turn may limit the height that can be achieved or increase the amount of material used, thus increasing costs.
In addition, construction methods employing larger columns, particularly when grouped at corners or occurring at intermediate locations within the walls, result in greater space between modules, and/or walls of increased thickness that reduce the usable floor area of the resulting building, and/or limit the free use of voids and walls for purposes of installing equipment such as for cubicles and shower stalls, and/or the occupants put other restrictions on the use of space, thereby reducing the value of the resulting building.
In addition, the modular building construction method employing the second frame increases assembly time for the building, increases cost and duration of construction and reduces available floor area, thereby reducing the value of the resulting building.
Because the increased variation increases the number of specific parts that must be measured, cut, and stocked until used, it is not desirable to form a variety of different module types each with unique details with respect to the forces acting on the modules within the building. In addition, the arrangement of the manufacturing tools, which require precise positioning of the parts with respect to each other for assembly, is error-prone and therefore generally carried out by the skilled person, any increase in the number of arrangements thus increasing production time and costs.
Since the components comprising the mesh structure must be nearly the same length, creating the multiple features required to accurately assemble the modules by welding or otherwise, subsequent positioning and attachment of the subassemblies from which the modules are manufactured, suspension and lifting of the finished modules, and fastening of the modules to form a structurally friendly grouping that provides redundancy and adequate load paths as currently practiced requires many precision cutting and assembly operations, which increases cost.
It is well known in the art that moment-connected module frames or building frames reduce the need for diagonal reinforcing elements that would otherwise obstruct the view of occupants and obstruct the installation and maintenance of building equipment. However, the moment connections required for the expansion splice plates as connection devices require clear access to one or more faces of the module, thereby increasing the amount of packaging and finishing work that must be done on site.
Some embodiments of modular buildings best suited to field conditions, the needs of the occupants and the aesthetic tastes of architects or owners may be composed of modular forms having non-right angle shapes, including tapered, curved, polygonal, etc., however, existing systems for construction of structural modules adapted to high rise building structures are not inherently suited to non-right angle shapes.
The varying shape of the modules and the varying positions of the walls, fixtures and other components cause the center of gravity of the modules used to construct a building or to lay the individual floors of the building to vary. To facilitate the arrangement while reducing the clearance to a minimum, it is desirable to have the side walls of the modules oriented as close to vertical as possible during lifting. The fact is that lengthy delays and repeated trial lifts are required to cause adjustment of the rigging to achieve this desirable condition. The time required to effect the required change in turn increases the overall duration of the lifting operation, thus increasing the cost for the workers and equipment, such as cranes, and delaying the completion of the building.
The need for less precise placement and interconnection of the modules increases the amount of space required between the modules, which increases the difficulty of making the structure fire resistant and interconnecting the members in order to achieve the greatest possible strength, as well as makes integration of the modules into the structural group more difficult, as well as wasting space and providing space for the circulation of sound, smoke and parasites.
The size of the modules and the positional arrangement of the components within the modules define the location and size of the exterior wall finish, mechanical maintenance, adjoining and abutting modules and support structure beneath the building and have interdependencies between all elements making up the modular building.

Detailed Description
The application of the invention disclosed herein, and some related aspects, as will be recognized by those skilled in the art, have been illustrated and disclosed in related PCT application number PCT/CA2014/050110, filed 2, month 14, 2014, the subject matter of which is incorporated herein by reference.
The present invention helps to solve the need for a compact, precise, supporting load, connecting torque, versatile and complete system for orienting and assembling the relevant components of the module frame, which can facilitate the quick and reliable installation and lifting of the finished modules and provide for the connection of the modules to each other and to other necessary components of the building without the need for excessive unfinished area, so as to fully utilize the structural characteristics of the modules, which define and reduce the number of parts, provide features that do not require the implementation of complex connections in the manufacturing coupling area, excessive precision in the cutting of the required materials, and difficult locations and difficult welds in multiple precise configurations.
In particular, the invention relates to a system for manufacturing and assembling building modules and interconnecting the modules to form components of a building made up of these modules, and also to a method for defining the number, selection and articulation of those components for forming modules suitable for a particular structure.
The present invention may also help address the need for a system of components and methods of operation that allow manufacturers to economically and safely construct various types of buildings, from a single dwelling to many forms of tall buildings, including but not limited to right angle, conical, radial, and curvilinear shapes, that exceed 20 stories.
This description has been initially divided into sections for each component or group of components for ease of reading.
Corner block
The present invention provides upper and lower load bearing connectors or blocks which in one embodiment are corner blocks. In particular embodiments, the blocks are substantially quadrilateral, and in other embodiments have a polygonal or asymmetric shape. These blocks can be mass produced with features that provide multiple functions, to concentrate on precise operations in small numbers and sizes of objects, and to reduce the number and complexity of jobs that must be performed on other components. The upper and lower blocks have different forms and in one embodiment are located on the upper and lower ends of vertical corner members (columns) of generally inclined, tubular or fabricated form which perform the function of the multi-layer columns when the modules so constructed are joined to form larger or higher structures using features on the blocks.
Likewise, when the modules so constructed are connected to form a larger or wider structure, other features on the blocks engage the horizontal members of the building and perform the function of a continuous horizontal member.
In particular embodiments, the block has arms that project at a plurality of angles including, but not limited to, perpendicular to the surface of the block for providing positioning and welding of the abutment members at the plurality of angles. In particular embodiments, the present invention thus facilitates the manufacture and installation of modules including, but not limited to, right angle, tapered, radiused, and curved. The positioning of the threaded holes in the arms and the unthreaded threaded fasteners, the vertical walls of the arms provide for an increase in load bearing capacity and the transfer of compressive and tensile forces resulting from forces acting on the building and from the action of the fasteners.
In particular embodiments, the blocks have holes in both the body and the arms for passing bolts with nuts therethrough and receiving the bolts, or the holes are threaded to receive the bolts, so as to provide for continuity of vertical tension through the columns and torque against interconnection between adjacent modules or with other building structures. The tension resistance caused by the connection of the columns in the vertical plane enables the mechanism to resist the lifting that occurs and to create friction on the gusset plate to transfer forces to the cross member along the horizontal plane with a high degree of stability.
More specifically, the surfaces of the arms abutting against the gusset from above and below are made strong during assembly.
In particular embodiments, the bolts are accessible within a wall cavity or other such location and may be disposed flush with or below the surface such that the removable patch can be easily configured to cover the location of the bolts and ensure continuity of the refractory material surrounding the load support structure. In the same embodiment as attached to the underside of the roof assembly, the bolt may be inserted from below and up.
In particular embodiments, the block has protruding features on the distal face of the block that are positioned to provide a backing for assembly welding, reduce structural impact on welding of connecting members that are cut too short or have external square ends or other disadvantages, reduce the probability of workers making inconsistent welded connections between corner blocks and members welded to the block, and the sloping features so positioned on the exterior of the block are positioned so as to reduce the likelihood that the weld will need to be ground so that they do not protrude beyond the surface and interfere with adjoining modules.
The holes in the corner blocks provide a means of connection to the binding and lifting devices. In a particular embodiment, the upper face of the block is provided with an opening into which a quick-release connector can be inserted in order to provide means for quickly and reliably connecting and disconnecting the module to the lifting device.
In a particular embodiment, the block has features on the contact face that engage corresponding features on the gusset to increase resistance to sliding along the contact plane that may occur during a seismic event.
In a particular embodiment, the block has a projecting flange that is coplanar with the face on which the floor or ceiling finishing is applied to provide a continuous backing in the area of the fastener access, which is omitted to provide air tightness and support to the floor or ceiling material. In use, the flooring covers the top face of the frame to the end of the arm of the block, but is cut away at the block to expose the top face, allowing for bolt insertion for assembly. This may leave the floor unsupported. The flange shown may help support the floor in this area and help form a continuous surface so there are no cracks in the seal between the floors, which may help to resist fire.
In a particular embodiment, the block has a plurality of holes on the vertical surface for attachment of accessories such as balconies, hallways and decorative treatments.
In particular embodiments, the block has one, two, three or more holes for the passage of vertical tension fasteners, there being one such hole for each vertical structural member that may be centrally located over the hole. In another specific embodiment, there are two or more holes for each vertical member. The length of the arms on the blocks through which the fasteners pass and the length of the arms on the gussets between the blocks vary with respect to the number of these holes.
In particular embodiments, the lower block has openings through the surface to reduce the amount of steel that must be drilled or removed from the casting to allow the bolts to pass through. In combination with this feature or separately, the block may be reinforced with ribs to increase load carrying capacity and resist twisting.
The other component is a feature on one end that is prepared to receive a tubular structural member of one size and a feature on the other end that is prepared to receive a tubular member of another size, or a corresponding feature of a block, and has tapered sides and internal ribs or other stiffening means to transfer forces between the two members without twisting. As shown in fig. 40, it is desirable to vary the size of the columns with respect to the load. Smaller columns are used in the less loaded upper parts of the building and larger columns are used in the more loaded lower parts due to the accumulated weight load and increased overturning forces. The same sized column of the components shown in fig. 27 is placed on top of the next larger size connector, for example a 4 "x 4" column is placed on a 6 "x 6" connector block, which is then placed on a module with 6 "square columns. This eliminates the need for a dedicated adapter block with two different final configurations because it has expensive tooling but low throughput.
The other part is a block configured so as to allow welding of the columns made of plates to its external vertical faces, so as to directly support or connect to a similarly prepared connection or block of the type previously described. As understood by those skilled in the art, two or more such columns coupled into a T-shaped or X-shaped structure may achieve a large weight per foot and an increased cross-section that results in greater buckling resistance without protruding into the occupied space of the building.
Gusset plate
The other part is a plate inserted between the blocks at the top and bottom ends of the column or column set, the plate having upwardly tapered locating pins for engaging and guiding the lowered module by sliding contact with corresponding locating recesses on the underside of the corner block to locate the module in the correct position for fastening. The plates also provide through holes for connecting adjacent modules with bolts to provide structural continuity in the horizontal plane during construction and in the finished building by virtue of their ductility for accommodating slight variations in column length to ensure a continuous load path equally supported on all the members of the column set formed thereby. As will be appreciated by those skilled in the art, the plate may be shaped to fit between a single vertical column or between two or more columns arranged at right angles or in other configurations. In a particular embodiment, shims of similar size and prepared with appropriate holes are provided in one or both sides of the connection to accommodate variations in the final dimensions of the module, thereby maintaining the correct geometry of the module stack.
In a particular embodiment, the gusset is provided with projections on its upper and lower faces that engage corresponding grooves in the contact faces above and below the block to provide resistance to sliding movement that may occur during a seismic event and to reduce the load that such movement would apply to the journal of the vertical tension fastener.
Stairwell and elevator shaft
The system of the present invention allows for the manufacture of modules in which stairways or lifting devices are installed that are separated at the mating line between the two modules without significant visible or functional disruption.
Super high module
The system of the present invention allows for the manufacture of modules comprising upper and lower halves of an habitable volume that is above the normally allowed transport limits and is coupled at mating lines between two or more stacked modules without significant visible or functional disruption.
Entrance hall
Another group of components of the invention are structural hall floors, which are made of, for example, reinforced concrete, sandwich panels, wood or formed metal together with a support base. In a particular embodiment, the slab is composed of reinforced concrete with reinforcing rods arranged such that features on the support base engage the reinforcing rods so as to resist bending of the base, thereby forming a torque connection between the stacks of adjacent modules connected thereby. The base is provided with holes aligned with corresponding holes in the upper and lower corner blocks and is used to connect two parallel stacks of modules and to connect adjacent columns within the stack on one side so as to form a combined load path. The base and floor slab may also be connected to the sides or ends of the module stack on one side of the slab and to the balcony support frame on the outside to form a building with a balcony or connecting porch. The floor slab and base assembly can also be used as a convenient carrier for construction equipment such as pipes, tubing and wiring to facilitate off-site manufacture of these components in a factory environment.
In particular embodiments, the gusset may be extended as desired and provided with holes for the passage of fasteners to support and engage accessory support and connection assemblies of various sizes.
Interdependence details of a system
The invention also includes a predetermined grid on which the dimensions of the interconnected elements of the subject building are based together with the system of devices, which ensures that the grid remains throughout the entire manufacturing assembly along all axes, which ensures precise and interdependent relationships extending from corner blocks to components, to subassemblies, to modules and to the entire building along all axes. The sizing system is therefore used to reduce the sizing element and module size, to increase the number of common parts and to reduce the coordination difficulty with the foundation and the pier contractors, which facilitates the task of integrating all internal or external suppliers of components into the module thus manufactured.
In a specific embodiment, the system is based on increments along three axes no greater than or no less than two inches, the center-to-center precision between holes for fastening being ± 1/32 ", the outside-to-outside dimensional precision of all matching surfaces being plus 0" -, -1/16 ".
Fixture for mounting a component to a vehicle
The present invention includes a system for assembling a frame of modules that ensures that the modules conform to the grid established as above, with no portion of the modules protruding beyond the furthest ideal dimension, which increases the achievable speed of assembly and improves the accuracy of the structure, eliminates the possibility of additional dimensional drift, results in difficulties in installation, fire resistance, reduced possibility of interconnecting the modules with greater stability, and reduces wall thickness and wasted space.
Platform fixture
The components of the system of the present invention include a planar platform or adjustable fixture mounted on a fulcrum to allow pivoting of the planar platform, the adjustable fixture being of sufficient thickness and prepared with grid holes to accommodate vertical pins so positioned to orient the components of the modular ceiling or floor frame for assembly welding, thereby forming a modular sub-assembly such as a floor, ceiling and wall. The locating holes are laid to ensure that the modules conform to the grid established above, the grid cooperating with other building elements to ensure that the resulting modules are easily assembled to form complete modules which can be assembled to form a building. The pins are equipped with a spacer system for ensuring the correct lifting of the components of the assembly in order to create flush conditions for the application of floor or ceiling surfaces as required. The fixture is thus configured to ensure that welding is performed in a position that is ideal for a structural weld so as to ensure that the finished part does not exceed a tolerance envelope that causes a cumulative tolerance condition.
Rotary fixture
Another component of the invention is to orient the ceiling framing, floor framing, corner columns, intermediate columns, column reinforcements and diagonally supported adjustable and rotatable fixtures of all multiple dimensions to one another for assembly welding to ensure that the modules conform to the grid established as above to ensure ease of module interconnection and to ensure that the finished part does not exceed the tolerance envelope and that the part can be oriented in the desired position for achieving a structural weld.
Quick connect lifting connector
Another component of the invention is a releasable and compact quick connector used to attach the lifting device to the module, mounted from above in a specially prepared opening in the corner block without tools, prevented from being accidentally released and able to be removed without tools. In a particular embodiment, the configuration of the connector is ideal in that the upwardly facing bearing surfaces of the toggle and the corresponding downwardly facing bearing surfaces of the receiving block and the tensile load portion of the toggle shaft which transfers load from the bearing surfaces to the lifting apparatus are ideally proportioned to maximize the load carrying capacity of the composite member in the most compact space while maintaining the dimensional constraints of the assembly in the top surface of the toggle block.
Lifting frame
Another component of the invention is a lifting device arranged to suspend a load in a desired attitude for placement in a building, which in a particular embodiment is horizontal and provides for rapid adjustment of the position of all connection points from which the line extends to the crane hook to compensate for differences in the centre of gravity that occur in the length of the module. The illustrated device also allows for varying the spread between a pair of cables on one side of the frame, affecting the variation of the angle of variation and the perpendicular of a pair of lines extending to the crane hook on one side of the module, so as to attach the center of the crane to one side of the long axis of the frame, thereby compensating for the variation of the center of gravity of the load occurring across the width of the module suspended therefrom.
Reinforcing member
In addition, the present invention includes a system of standardized reinforcement members connected to each other and to the columns, transverse frames, diagonal braces and corner blocks described herein, eliminating the need for item-by-item design and manufacturing or customization of the reinforcement components.
Reinforcement analysis
In addition, the invention comprises a working method for systematically analysing the forces acting on a building, which is composed of modules, defines the optimal positions for applying a standardized stiffening system, is selected from a series of standardized stiffeners with progressive deflection and lifting resistance and therefore incorporates only such stiffeners as have the minimum requirement to stiffen the area under additional stress, without adding unnecessary structural material beyond that required to more positions, without significantly damaging the application of refractory material and without requiring additional thickness of the walls of the modules.
Combined column
Furthermore, the present invention includes methods for manufacturing and connecting the outer columns so that they form groupings with greater resistance to compressive and tensile forces caused by loads encountered in the construction of tall and/or elongate buildings.
In particular embodiments, resistance to horizontal drift, deflection, or lifting of the columns is increased by welding or otherwise suitably joining two or more columns into groups along their vertical edges and welding or attaching the groups to connector blocks in areas provided for that purpose.
In a particular embodiment, the columns are composed of plates joined along their edges by welding or other suitable methods, these components being welded or joined to the blocks. In particular embodiments, the plates have a thickness of 1 "or greater. In another particular embodiment, the plate columns bypass the block to which they are welded and contact the top and bottom surfaces of the gusset along the ends of the plate.
In a particular embodiment, the columns are progressively larger and engage blocks having correspondingly larger bodies and connection features. In particular embodiments, the pillars are 4 "squares, 6" squares, 8 "squares, 10" squares, rectangles, etc., or equivalent metrics corresponding to standard structural hollow metal or composite profiles.
Advantageous effects
Increase height without frame
By eliminating the inadvertent formation of connections that are not fully compressed and therefore not fully secured during assembly, and by providing a greater number of fasteners and by facilitating the placement of reinforcements, the system and method of operation of the components of the present invention can be used to increase the height of a building that can be built without the need for a second external or internal support frame, can be used to increase the available floor area thereof due to the increased stability of the connections, the formation and determination of multiple and redundant load paths, the integration of support frames into the module walls, and the resulting effective transfer of external, internal and self loads applied to the finished building by adjacent modules and thus to the ground.
Using frames to increase height
The invention also serves to increase the height of a building constructed with a second external or internal support frame of given dimensions, by reducing the amount of steel required for the upper floor and thus its overall weight.
Reducing the number of special parts, the number of positions and the size of the components
By analyzing the applied loads and more efficiently involving more required components in the structural function, the present invention also reduces the size of the required components, as well as limiting the number, size and location of situations where specialized reinforcement details and associated fire-resistance complexity are required, thereby reducing the cost of these buildings.
Reducing the need for precision
The present invention may help to further reduce the precision of parts that must be produced by workers in a modular production facility, which reduces manufacturing costs.
Reducing manufacturing complexity
The present invention concentrates many of the complex features required for link members, lifting modules and link modules in a single mass-produced part, helping to reduce the complexity and need for the skilled work required to build the modules.
Allowing higher and wider
In addition, the system may allow for a building with a taller module consisting of two stacked frames, one with an opening in the ceiling and the other with an opening in the floor, a longer module due to support performance and a wider module due to improved performance of the holes in the ends, thereby providing greater flexibility to the designer of a building so constructed.
Reducing wall thickness
By distributing the load bearing members more perfectly, the present invention can help reduce the wall thickness required for the containment structure and facility.
Reducing field labor for repair
By placing tensile connections within the wall cavity and concentrating the connection means in the vicinity of the pillars, the present invention can help reduce the number and extent of the lost circulation regions that must be subsequently repaired.
The present invention according to the embodiments disclosed in the specification will now be described with reference to the accompanying drawings.

In one embodiment, the connector body (102, 4) is 4 "square to receive a 4" x4 "Hollow Structure Section (HSS). In another embodiment, the connector body (102, 4) is a 6 "square that receives a 6" x6 "HSS. The
The connector assembly may be formed by clamping gussets (82, 92) between the upper and lower connectors (fig. 10 and 11). The gusset (82, 92) has two faces, a first face that can be in contact with the lower connector and a second face that can be in contact with the upper connector. In addition, the gussets (82, 92) are provided with through
The arms of the connector also have bosses (44, 122), the bosses (44, 122) providing location of the longitudinal and transverse members of the module frame and a base for assembly welding. In the shown embodiment, the edges of the arms of the upper and lower connectors have bevelled edges. The chamfer (34, 124) provides a location for the weld bead, which allows the weld bead to be disposed flush and eliminates the need for tilting the connected components.
The exterior of the connector body may have a plurality of holes (or bores) that are tightened or unscrewed by use of bolts, pins, clips, coupling plates, or other fastening devices as required by the environment for the connection of groups of columns, hall plates, fixtures, lifting devices, or other useful features. In another embodiment, the connector is taller and additional holes are provided for additional fasteners or to add additional support or other features. In another embodiment, the connector has more or less than 4 sides and is non-quadrilateral, but has a scalene quadrilateral, parallelogram or other shape to facilitate production of a circle, curve, conical star or other building form.
As described above, the
In one embodiment, the

To form the floor frame of the module, the longitudinal floor beams and the transverse floor beams are cut to length (fig. 9 and 10). In a specific embodiment, the beams are 3 "x 8" for the HSS with a perimeter and 3 "x 6" for the filler members. Because the locating and welding fixtures described herein locate the pre-fabricated connector blocks and define the hole locations and their mutual positions, and provide the external dimensions of the assembly, the fixtures ensure that the modules manufactured with the fixtures conform to the previously described established grid. In addition, the features on the block ensure that the beam does not need to be tilted on the edge of the end and that the cutting to length operation is not important in terms of length and square. The beams are coupled to
One skilled in the art will recognize that the assembly of a ceiling employs a similar process utilizing appropriately sized components disposed in the same fixture. In a specific embodiment, it is a 3 "x 3" HSS for the periphery with a2 "x 2" HSS for the filling members. Thus, both the top and bottom frames capture and coordinate the external dimensions of the same fixture.
Suitable materials, such as fiber cement boards, or sheet steel and concrete tops, or steel composite boards, are used for the top surfaces of the floor beams of the modular floor, thus being constructed and appropriately fastened, or concrete or other materials are filled between the frames in order to support the occupant loads and to provide the desired barrier action to the modules and then to the building made up of the modules. Similarly, materials such as drywall or fire resistant panels and various types of insulation depending on the environment are used in the framing and the surfaces of the panels and in the voids of walls and ceilings to provide various functions such as privacy for the occupants, to provide structural to fire resistance, and to limit the transmission of sound. Please see the
By locating the boss, which acts as a locating means and backing on the arm connecting the solder structure to the block, at the distal end of the arm rather than at its base, the present invention eliminates the need for a hole in the HSS and locates the load bearing face abutting the connector body in direct contact, thereby ensuring a connection with a high degree of stability and less likelihood of settling due to incorrect assembly.
This direct contact ensures that the connection formed by the components can extend the full length, with the load transfer capability of the connection reducing the amount of work required to prepare the connector and HSS for assembly.
In addition, the structure of the connector of the present invention provides for a greater number of fasteners to increase the tension capacity of the connection and a greater area for connecting auxiliary reinforcing members, which increases the buckling resistance and tension capacity of the produced structure (fig. 22, 28-32).
