Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their detailed description will be omitted.

Fig. 1 is a structural diagram of the fastening and leveling device provided in the embodiment of the present invention after being applied to an anchor bolt cage. Referring to fig. 1, the anchor cage includes an upper anchor plate 10, a lower anchor plate 20, and an anchor 30 connected between the upper anchor plate 10 and the lower anchor plate 20. Specifically, the upper anchor plate 10 may be located above the lower anchor plate 20, and the upper anchor plate 10 and the lower anchor plate 20 have anchor holes for installing the anchor bolts 30, respectively, the anchor holes located on the upper anchor plate 10 being aligned up and down with the anchor holes located on the lower anchor plate 20 to facilitate penetration of the anchor bolts 30, the anchor cage being formed in a cylindrical structure with an inner cavity formed at the center thereof.

The upper anchor plate 10 and the lower anchor plate 20 are both of a split structure. Specifically, the upper anchor plate 10 and the lower anchor plate 20 are both circular rings and are divided into a plurality of arc segments along the circumference, and two adjacent arc segments can be connected together through the connecting plate 61. Specifically, adjacent arc segments may be overlapped by a connecting plate 61, and the connecting plate 61 may be fixed to the end of the arc segment by a fastener. The upper anchor plate 10, the lower anchor plate 20, and the plurality of anchors 30 of the anchor cage can be pre-assembled together to form the anchor cage. The fastening and leveling device can also be arranged on the anchor bolt cage, so that the fastening and leveling device can be used for supporting the anchor bolt cage in the transportation and hoisting processes of the anchor bolt cage, preventing the anchor bolt cage from deforming, and leveling the anchor plate after the anchor bolt cage is hoisted to a machine position.

The tightening leveling device according to an embodiment of the present invention includes an inner tensioning assembly 40 located within the interior cavity of the anchor cage and an outer leveling assembly located at the outer periphery of the anchor cage. The inner tension assembly 40 can be supported between the upper anchor plate 10 and the lower anchor plate 20 to further improve the structural stability of the anchor bolt cage and prevent the anchor bolt cage from deforming during transportation and hoisting. During the leveling process, the outer leveling assembly can apply a pulling force to the upper anchor plate 10 and the lower anchor plate 20, and the inner tensioning assembly 40 can provide a pushing force opposite to the pulling force, so that the distance between the upper anchor plate and the lower anchor plate is tensioned or loosened, and the levelness of the upper anchor plate meets the installation requirement.

The inner tension assembly 40 may include at least two diagonal support rods 41 connected between the upper anchor plate 10 and the lower anchor plate 20 and symmetrically disposed, and the two diagonal support rods 41 may be arranged to cross to form a scissor-brace. Both ends of the diagonal support bar 41 are connected to the upper anchor plate 10 and the lower anchor plate 20, respectively, to be supported between the upper anchor plate 10 and the lower anchor plate 20, so that it is possible to prevent deformation during transportation or hoisting. The length of the diagonal support bar 41 is adjustable so that the supporting force applied to the upper and lower anchor plates 10 and 20 or the levelness of the upper and lower anchor plates 10 and 20 is adjusted by adjusting the length of the diagonal support bar 41.

The outer leveling assembly may include at least two longitudinal support rods 51 connected between the upper anchor plate 10 and the lower anchor plate 20 and substantially parallel to the anchor bolts 30, symmetrically arranged along the circumferential direction of the anchor cage. The length of the longitudinal support rod 51 is adjustable, so that the leveling operation before pouring of the anchor bolt cage can be realized, the structure is simple, and the leveling step is simplified.

After the crab-bolt cage assembly is accomplished, can install the inboard at the crab-bolt cage with interior tensioning set 40 earlier, carry out preliminary fixed to the crab-bolt cage, play the effect that prevents the deformation of crab-bolt cage. Meanwhile, it is also possible to appropriately apply an outward tension to the upper anchor plate 10 and the lower anchor plate 20 by adjusting the length of the inclined support rod 41. When transporting the crab-bolt cage to pouring the on-the-spot back, can set up the periphery at the crab-bolt cage with outer leveling subassembly to this crab-bolt cage leveling. During the leveling process, the anchor cages are prevented from being excessively deformed due to the presence of the inner tension assembly 40, for example, the outer leveling assembly can apply a pulling force to the upper anchor plate 10 and the lower anchor plate 20 to cause the upper anchor plate 10 and the lower anchor plate 20 to have a tendency to approach each other. Of course, the outer leveling component can also be installed after the anchor bolt cage is assembled, so that the outer leveling component can further prevent the anchor bolt cage from deforming in the transportation and hoisting processes, and the stability of the anchor bolt cage is improved through the synergistic effect of the inner tensioning component 40 and the outer leveling component.

The inner tensioning set 40 is mounted to the anchor cage and, without applying an external force to the anchor cage, the inner tensioning set 40 may apply no pushing or pulling force to the anchor cage and, with the outer leveling set mounted, the outer leveling set may apply no force to the anchor cage. Because interior tensioning part 40 and outer leveling subassembly are rigid structure respectively, just can produce the opposite direction, the same power of size to the effort of crab-bolt cage under the circumstances that the crab-bolt cage received external action power to prevent that the crab-bolt cage from warping.

Fig. 2 is a block diagram of the fastening and leveling device of the anchor cage of fig. 1, wherein the anchors are omitted from fig. 2 for clarity. Fig. 3 is a partially enlarged view of a portion of a frame a in fig. 2. Fig. 4 is a partially enlarged view of a portion of a frame B in fig. 2.

Referring to fig. 2 to 4, in particular, an inner tension assembly 40 may be located within the inner cavity of the anchor cage, wherein the inner tension assembly 40 includes at least two inclined support bars 41, the two inclined support bars 41 crossing each other to form a scissor-like structure, and 6 inclined support bars 41 are shown crossing each other in fig. 2 as an example.

In a plane projected along the axial direction, both ends of the diagonal support bar 41 are arranged symmetrically with respect to the axis, and therefore, the diagonal support bar 41 will intersect with the axis of the anchor cage. The plurality of diagonal support rods 41 may be fixed integrally at positions intersecting the axis of the anchor cage. For example, the plurality of diagonal support rods 41 may be cut into two pieces in a desired length and welded together at the intersecting positions, thereby preventing the cross interference between the plurality of independent diagonal support rods 41.

Both ends of each diagonal support rod 41 are connected to the upper anchor plate 10 and the lower anchor plate 20, respectively, to be able to apply a pushing force to the upper anchor plate 10 and the lower anchor plate 20 of the anchor cage. Specifically, each of the diagonal support rods 41 is a length-adjustable structure, and by adjusting the length of the diagonal support rod 41, the direction and magnitude of the force applied by the diagonal support rod 41 to the upper anchor plate 10 and the lower anchor plate 20 can be adjusted. The plurality of diagonal support bars 41 may be identical in structure and length.

As an example, the inclined support bar 41 may include a first support bar 4131, a second support bar 4132, and a length adjustment assembly connected therebetween, which are disposed opposite to and spaced apart from each other, the first support bar 4131 being connected at an upper end thereof to the upper anchor plate 10, and the second support bar 4132 being connected at a lower end thereof to the lower anchor plate 20. By the length change of the length adjustment assembly, the distance between the first support bar 4131 and the second support bar 4132 can be adjusted, so that the entire length of the inclined support bar 41 can be adjusted.

As shown in fig. 2 and 4, the length adjustment assembly includes a threaded rod 4202 and first and second adjustment nuts 4201 and 4203 that are threaded onto the threaded rod 4202. The upper end of the threaded rod 4202 is inserted into the through hole of the lower end of the first support bar 4131, the lower end of the threaded rod 4202 is inserted into the through hole of the upper end of the second support bar 4132, and the distance between the lower end of the first support bar 4131 and the upper end of the second support bar 4132 can be adjusted by adjusting the positions of the first and second adjustment nuts 4201 and 4203 on the threaded rod 4202, so that the entire length of the inclined support bar 41 can be adjusted.

As an example, the lower end of the first support bar 4131 and the upper end of the second support bar 4132 are respectively formed with end plates perpendicular to the length thereof, the end plates are formed with mounting holes, the first adjustment nut 4201 abuts against the bottom surface of the end plate of the first support bar 4131, the second adjustment nut 4203 abuts against the top surface of the second support bar 4132, and the first adjustment nut 4201 is rotated to move the first adjustment nut 4201 upward with respect to the threaded rod 4202, thereby pushing the first support bar 4131 upward. Similarly, when the second adjustment nut 4203 is rotated, the second support rod 4132 is moved downward by the pushing force of the second adjustment nut 4203. Therefore, when adjusting the length of the diagonal support bar 41, only the first adjustment nut 4201 or only the second adjustment nut 4203 may be adjusted, and of course, it is also possible to adjust the first adjustment nut 4201 and the second adjustment nut 4203 at the same time.

Further, in order to improve the support stability of the inclined support rod 41, the length adjustment assembly further includes a first fastening nut provided on an upper end of the threaded rod 4202 above an end plate of the first support rod 4131, and a second fastening nut provided on a lower end of the threaded rod 4202 below an end plate of the second support rod 4132. The first and second fastening nuts 4202 may be rotated after the first and second adjustment nuts 4201 and 4203 are adjusted to the proper positions, thereby preventing the threaded rod 4202 from being loosened.

The upper end of the diagonal support bar 41 may be fixedly connected to the upper anchor plate 10 by an upper end connector, preferably formed as a lifting seat 4111 for connection to a lifting device. The hanger 4111 is detachably coupled to the upper anchor plate 10 and to the upper end of the diagonal support bar 41.

Lifting lugs 4112 can be arranged on the lifting seat 4111 for lifting. To facilitate connection with the upper end of the diagonal support bar 41, one side of the hanging seat 4111, which is located at the radially inner side of the anchor cage, may be provided with a lug 4113, and the lug 4113 may be connected to the upper end of the diagonal support bar 41, for example, but not limited thereto, by a fastener.

Specifically, the hanger 4111 may include a top plate, a bottom plate, and a vertical plate connected between the top plate and the bottom plate, which are parallel to the upper anchor plate 10. The lifting lug 4112 may be located on the top plate, because the lifting lug 4112 may be disposed on the lifting seat 4111 connected to the upper anchor plate 10, rather than being directly disposed on the upper anchor plate 10, so as to avoid directly lifting the upper anchor plate 10 to cause bending deformation.

The riser may be perpendicular to the upper anchor plate 10 and extend to the inner side of the upper anchor plate 10 in the radial direction of the upper anchor plate 10 to protrude radially inward of the upper anchor plate 10, and the protruding portion may serve as a lug 4113. The lug 4113 may be integrally formed with the vertical plate or may be separately formed and then connected to the vertical plate. The lug 4113 is provided with a through hole for passing a fastener therethrough, which may be a kidney-shaped hole, herein referred to as a first kidney-shaped hole 4114. The upper end of the first support bar 4131 is provided with a second waist-shaped hole 4133, as shown, the second waist-shaped hole 4133 is adapted to the first support bar 4131, and a fastener may be disposed in the first waist-shaped hole 4114 and the second waist-shaped hole 4133 to connect the hanging seat 4111 with the first support bar 4131. The first kidney shaped aperture 4114 may extend in a radial direction of the anchor cage and the second kidney shaped aperture 4133 extends along a length of the first support strut 4131. By forming the kidney-shaped hole, fine adjustment can be performed after the diagonal support bar 41 is tensioned.

Before the anchor cage is cast, the inner tensioning assembly 20 can be disassembled, for example, the disassembling step can be reversed from the assembling step.

The outer leveling assembly can comprise at least two longitudinal support rods 51, by way of example 4 longitudinal support rods 51 in fig. 2, arranged symmetrically in the circumferential direction of the anchor cage. The longitudinal support bar 51 may include first and second longitudinal bars 511 and 512 connected to the upper and lower anchor plates 10 and 20, respectively, and a length adjustment member 513 connected between the first and second longitudinal bars 511 and 512. The length adjustment member 513 includes an upper threaded rod 5113, a lower threaded rod 5111, and a threaded bracket 5116 threadedly coupled to the upper threaded rod 5113 and the lower threaded rod 5111, wherein the threads of the upper threaded rod 5113 and the lower threaded rod 5111 are oppositely threaded, and the length of the upper threaded rod 5113 and the length of the lower threaded rod 5111 extending into the threaded bracket 5116 can be adjusted by rotating the threaded bracket 5116, thereby adjusting the length of the longitudinal support rod 51.

Specifically, the upper end of the first side rail 511 may be coupled to the upper anchor plate 10, the lower end of the second side rail 512 may be coupled to the lower anchor plate 20, and the length adjustment member 513 may be coupled to the opposite ends of the first and second side rails 511, 512. The two ends of the longitudinal support rod 51 are detachably connected to the upper anchor plate 10 and the lower anchor plate 20, and specifically, the first longitudinal rod 511 and the second longitudinal rod 512 can be connected to the upper anchor plate 10 and the lower anchor plate 20 through U-shaped clamping plates, and U-shaped grooves of the U-shaped clamping plates can be clamped at the inner edge or the outer edge of the upper anchor plate 10.

As an example, referring to fig. 3, the upper end of the upper threaded rod 5113 has a first U-shaped connecting portion 5118, and the first U-shaped connecting portion 5118 is hinged to a protrusion at the lower end of the first longitudinal rod 511; the lower end of the lower threaded rod 5111 has a second U-shaped connecting portion 5117, and the second U-shaped connecting portion 5117 is hinged to a protrusion on the upper end of the second vertical rod 512. The first U-shaped connecting portion 5118 and the first vertical rod 511, and the second U-shaped connecting portion 5117 and the second vertical rod 512 may be connected by a pin 5112. Both ends of the screw bracket 5116 are formed with screw holes, and the upper screw rod 5113 and the lower screw rod 5111 are respectively combined into the screw holes of the screw bracket 5116, and specifically, the screw bracket 5116 includes a first internal screw part at an upper end into which the upper screw rod 5113 is inserted and a second internal screw part at a lower end into which the lower screw rod 5111 is inserted. By screwing the threaded bracket 5116, the length of the upper threaded rod 5113 and the lower threaded rod 5111 extending into the threaded bracket 5116 can be adjusted, so that the distance between the first longitudinal bar 511 and the second longitudinal bar 512 can be adjusted, and the length of the longitudinal support bar 51 can be adjusted.

During the leveling process, the longitudinal support rod 51 can exert a tensioning force on the anchor cage, i.e. the first longitudinal rod 511 exerts a downward pulling force on the upper anchor plate 10, and the second longitudinal rod 512 exerts an upward pulling force on the lower anchor plate, although this is not a limitation.

In addition, lock nuts are further provided between the first U-shaped connecting portion 5118 and the upper end portion of the screw bracket 5116 and between the second U-shaped connecting portion 5117 and the lower end portion of the screw bracket 5116, the upper lock nut 5114 is screwed on the upper threaded rod 5113, and the lower lock nut 5115 is screwed on the lower threaded rod 5111. By tightening the two lock nuts, the threaded bracket 5116 can be locked, preventing the threaded bracket 5116 from rotating loosely.

The longitudinal support rod 51 is connected to the clamping structure through a fastener and clamped at the outer side edges of the upper anchor plate 10 and the lower anchor plate 20 through the clamping structure, so that the longitudinal support rod 51 is of a detachable structure, the anchor bolt cage is convenient to remove after being leveled, the longitudinal support rod 51 can be repeatedly used, and the manufacturing cost of the fastening leveling device of the anchor bolt cage is reduced to a certain extent.

The fastening and leveling device for the anchor bolt cage can adjust the levelness of the upper anchor plate by adjusting the length of the longitudinal support rod 51, is time-saving and efficient, and simultaneously improves the stability of the anchor bolt cage in the transportation and hoisting processes.

As an example, the steps of mounting the outer leveling assembly to the anchor cage are: firstly, respectively clamping a clamping structure on corresponding positions of an upper anchor plate 10 and a lower anchor plate 20; the length-adjusting member 513 is then coupled between the first and second side rails 511 and 512, and the length of the longitudinal support bar 51 is adjusted by rotating the threaded bracket 5116. The mounting steps of the outer leveling assembly can also be adjusted as desired, but are not limited thereto. The outer leveling assembly can be disassembled prior to placing the anchor cage, which can be substantially the reverse of the assembly procedure.
