Background

For the construction of the existing fabricated composite slab, the common method is to divide the top plate into two parts, lay the conduit in the cast-in-situ layer of the top plate and finish the construction in a field wet operation. The thickness of the prefabricated laminated slab is 60mm, the requirement of routing is considered in the determination of the thickness of the cast-in-place layer besides the safety of the structure, and the thickness of the cast-in-place layer is at least 70-80 mm if the pipeline laying is crossed. For this construction mode:

(1) because the top plate has more pipelines, the pipelines are difficult to cross and even overlapped by three layers or more, which is not only not beneficial to protecting finished products, but also can influence the elevation of the finished surface of the floor slab;

(2) for the same house type in the field construction, because different personnel are used for construction, the laying modes of pipelines are different, so that the laying path of the pipelines in the top plate has great randomness according to the difference of the constructors, and if the phenomenon of pipe blockage occurs in the construction process, the difficulty of pipeline repair in the later period is great;

(3) after the roof pipeline is laid, because different work kind constructors cross operation, can go out the phenomenon that has a large amount of personnel to trample the pipeline, concrete placement in addition to the phenomenon that appears stifled pipe is more general.

(4) The indoor cable of the general strong electric box is the galvanized conduit of JDG32mm, the clearance between the lower part of the truss rib and the prefabricated laminated slab is small, and the line pipe can not pass through the area where the laminated slab is laid.

Detailed Description

The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and effects of the invention, but the present invention is not limited thereto.

The invention provides a pre-buried wiring method for standardized pipelines of assembled laminated slabs, which comprises the following steps:

the method comprises the steps of firstly, carrying out laminated slab reserved embedded point position synthesis, wherein each system has a set of independent drawings due to numerous electrical professional systems. In order to ensure complete equipment point positions in the prefabricated member and avoid damaging the prefabricated member when picking, chiseling and cutting are carried out on a construction site, reserved holes and embedded parts required by each system are integrated on one drawing, and a composite diagram of reserved embedded point positions of the laminated slab is provided. The leakage and the gap are conveniently checked, meanwhile, whether conflict exists in equipment point positions among systems and whether pipeline paths are overlapped or not is conveniently checked, and problems can be found and solved in time.

And secondly, performing pipeline optimal arrangement according to a pre-buried point comprehensive diagram reserved in the laminated slab. Indoor strong and weak current pipelines are led out from indoor strong and weak current boxes, and path planning is carried out according to different functions and positions of the pipelines. The method comprises the steps of planning paths of a common lighting pipeline, a kitchen pipeline, a toilet pipeline, a common socket pipeline, an air conditioner pipeline, a weak current pipeline and the like, reducing pipeline intersection as much as possible and providing a pipeline optimal arrangement diagram to ensure that the pipeline laying modes of the same house type in a construction site are the same and facilitate later-stage pipeline repair. The planned path of the pipeline avoids the water supply and heating pipelines laid in the decoration layer so as to prevent the laid pipeline from being damaged when the pipe clamp is installed.

And thirdly, planning a special pipeline wiring area aiming at an area with more inevitable pipeline concentration or intersection in the pipeline optimization layout, and carrying out independent optimization design on the area, wherein the thickness of the structural layer can be reduced through reasonable design, so that the construction cost is reduced.

For this pipeline routing region:

(1) the size of the pipeline wiring area is planned according to the number of pipelines and the pipeline cross overlapping condition: the arrangement of pipelines can not be close to each other, and the interval is not less than 2cm, so that the later cracking of the laminated slab caused by over concentration of pipelines can be avoided during pipeline laying.

(2) When the superimposed sheet is prefabricated, this pipeline wiring district prefabricated thickness reduces 1 ~ 1.5cm, forms a groove structure, places the pipeline in the inslot, makes things convenient for the later stage to lay the pipeline, and this kind of mode can make the power service pipe lay under the condition of continuous truss muscle to in the regional prefabricated superimposed sheet of this pipeline wiring, add phi [email protected] net piece muscle, fracture when preventing the superimposed sheet hoist and mount.

(3) During site operation, pipeline laying is carried out according to a pipeline optimal layout drawing, pipelines in a wiring area need to be standardized, neat and attractive, and after the pipelines are laid, the pipeline wiring area avoids truss ribs, transverse reinforcing steel bars and longitudinal reinforcing steel bars and is arranged on the lower layer of the laminated slab. The mesh reinforcing steel bars are additionally arranged on the upper portion, can be phi [email protected], and the width of the mesh reinforcing steel bars is not smaller than the width of the wiring area and extends 150mm towards the two sides respectively. The net-sheet rigid connection and other steel bars are attached as much as possible, so that the condition that the thickness of the upper-layer concrete does not meet the requirements of the protective layer is avoided.

And fourthly, after concrete pouring is finished, making marks in the wiring area to prevent pipelines from being damaged due to the fact that expansion bolts need to be used for punching in the later period.

Taking a specific house type as an example, fig. 1 is a plan view of a strong electric pipeline of a certain house type, fig. 2 is a plan view of a weak electric pipeline of the house type, fire fighting equipment is located in a public area, and the public area is generally a cast-in-place building area. Fig. 1 and fig. 2 are integrated into a reserved embedded point location integrated diagram (fig. 3). In fig. 3, the pipeline paths are disordered and have more cross-over areas, and in order to reduce pipeline cross-over, the paths of all pipelines are planned, as shown in fig. 4, the cross-over areas of the pipelines are reduced, and the inevitable overlap areas of the pipelines are planned to be special pipeline layout areas. The dotted line area in fig. 4 is the marked pipeline wiring area, please refer to fig. 5, the pipelines in the pipeline wiring area are arranged at intervals, the interval is not less than 2cm, the prefabricated thickness of the pipeline wiring area on the laminated slab is reduced by 1-1.5 cm to form a groove structure, the mesh reinforcing steel bar is additionally arranged below the groove structure, and the reinforcing steel bar mesh extends 150cm towards the two sides of the pipeline wiring area. And then pouring concrete, and after the concrete pouring is finished, making marks in the pipeline wiring area to prevent pipelines from being damaged due to the fact that expansion bolts need to be used for punching and the like in the later period.

Finally, it is noted that: the above-mentioned list is only the preferred embodiment of the present invention, and naturally those skilled in the art can make modifications and variations to the present invention, which should be considered as the protection scope of the present invention provided they are within the scope of the claims of the present invention and their equivalents.
