Description

Standardized pipeline pre-embedded wiring method of prefabricated laminated board

technical field

The invention relates to the technical field in the production and installation process of prefabricated construction projects, in particular to a pre-embedded wiring method of prefabricated laminated board standardized pipelines.

Background technique

For the current prefabricated laminate construction, the general practice is that the roof is divided into two parts, and the line pipes are laid in the cast-in-place layer of the roof, which needs to be completed by wet work on site. The prefabricated laminated board is 60mm thick. In addition to the structural safety, the thickness of the cast-in-place layer should also be considered. If the pipeline is laid cross, the thickness of the cast-in-place layer should be at least 70-80mm. For this construction method:

(1) Due to the large number of pipelines on the roof, it is inevitable that the pipelines will cross each other, and even three or more layers overlap, which is not only unfavorable for the protection of the finished product, but also affects the elevation of the finished surface of the floor;

(2) For the same type of house during on-site construction, the laying methods of pipelines will be different because of the construction by different personnel, which causes the laying path of pipelines in the roof to be very random according to the different construction personnel. During the construction process, the phenomenon of pipe blockage occurs, and it will be very difficult to repair the pipeline in the later stage;

(3) After the roof pipeline is laid, there will be a large number of people stepping on the pipeline due to the cross-operation of construction personnel of different types. Coupled with the concrete pouring, the phenomenon of blocking the pipeline is more common.

(4) The household cable of the general indoor strong electric box is JDG32mm galvanized conduit, and the gap between the bottom of the truss rib and the prefabricated laminated board is small, and this type of wire pipe cannot pass through the area where the laminated board is laid.

SUMMARY OF THE INVENTION

In order to solve the above technical problems, the present invention provides a pre-embedded wiring method for standardized pipelines of prefabricated laminated plates, which avoids damage to prefabricated components during chiseling and cutting at the construction site, and facilitates later maintenance.

In order to achieve this technical purpose, the present invention adopts the following scheme: a pre-embedded wiring method for standardized pipelines of prefabricated laminated plates, comprising the following steps:

S1. Carry out the synthesis of the pre-embedded points reserved for the laminated board: Integrate the reserved holes and pre-embedded parts required by different electrical systems on a construction drawing, and issue a comprehensive drawing of the pre-embedded points reserved for the laminated board;

S2. According to the comprehensive map of the pre-embedded points reserved for the laminated board, optimize the pipeline layout: lead the indoor strong and weak current pipelines from the indoor strong and weak current boxes, plan the path according to the role and location of the pipeline, and issue Pipeline optimization layout;

S3. In the pipeline optimization layout drawing, design a separate management and money wiring area for the areas where the pipelines are concentrated or intersected more: arrange the pipelines at intervals. When the pipelines intersect more than the cast-in-place layer cannot meet the requirements of the steel protection layer, the pipeline wiring area is prefabricated. The thickness of the laminated board is reduced by 1-1.5cm, and mesh reinforcement is added to the upper part of the pipeline;

S4. After the concrete pouring is completed, make a mark in the pipeline wiring area.

Compared with the prior art, the beneficial effects of the present invention are: the pre-embedded wiring method of the prefabricated laminated board standardized pipeline provided by the present invention avoids damage to the prefabricated components during chiseling and cutting at the construction site, and reserves pre-embedded points for integration. The diagram is convenient for checking leaks and filling vacancies, but also for checking the conflict of equipment points between various systems, so as to find and solve problems in time; after the pipeline optimization layout drawing is issued, the pipelines of the same house type on the construction site are laid in the same way, which is convenient for later pipeline repairs; The overlapping and intersecting areas are individually designed to reduce the thickness of the structural layer, which will not cause the later cracking of the laminated board due to the excessive concentration of pipelines, and reduce the project cost at the same time; after the concrete pouring is completed, make a mark in the wiring area to prevent the pipeline from being damaged later due to the construction process. .

The preferred solution of the present invention is:

Detailed ways

In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail by the following specific embodiments, but the present invention is not limited thereto.

The present invention provides a pre-embedded wiring method for an assembled laminated board standardized pipeline, the steps are as follows:

The first step is to carry out the synthesis of the pre-buried points reserved for the laminated board. Due to the large number of electrical professional systems, each system has a separate set of drawings. In order to ensure that the equipment points in the prefabricated parts are complete and avoid damaging the prefabricated components during chiseling and cutting at the construction site, the reserved holes and embedded parts required by each system are integrated on one drawing, and the prefabricated prefabricated panels are issued. A comprehensive map of pre-embedded points is reserved. It is convenient to check for leaks and fill gaps, and it is also convenient to check whether there is a conflict between the equipment points of each system and whether the pipeline paths overlap, so that problems can be found and solved in time.

The second step is to optimize the pipeline layout according to the comprehensive map of the pre-embedded points reserved for the laminated board. The indoor strong and weak electric pipelines are all led out from the indoor strong and weak electric boxes, and the path planning is carried out according to the different functions and positions of the pipelines. One general lighting pipeline, one kitchen pipeline, one toilet pipeline, one ordinary socket pipeline, one air-conditioning pipeline, and one weak current pipeline, etc., carry out route planning for each pipeline separately, minimize pipeline crossover, and issue an optimized pipeline layout to ensure The pipelines of the same house type on the construction site are laid in the same way, which is also convenient for later pipeline repairs. The planned path of the pipeline should avoid the water supply and heating pipelines laid in the decoration layer, so as to prevent the pipelines that have been laid from being damaged when the pipe clamps are installed.

The third step, in the pipeline optimization layout drawing, plan a special pipeline routing area for the inevitable pipeline concentration or cross-over area, and carry out a separate optimization design for this area. Reasonable design can reduce the structural layer. thickness, thereby reducing the project cost.

For this line routing area:

(1) Plan the size of the pipeline wiring area according to the number of pipelines and the overlapping situation of pipelines: the arrangement of pipelines cannot be close together, and the interval is not less than 2cm, so as to ensure that when the pipelines are laid, they will not be caused by excessive concentration of pipelines. Laminated board cracks later.

(2) During the prefabrication of the laminated board, the prefabricated thickness of the pipeline wiring area is reduced by 1-1.5cm to form a groove structure, and pipelines are placed in the groove to facilitate the later pipeline layout. Lay it under certain circumstances, and add Φ4@40mm mesh reinforcement in the prefabricated laminated board in this pipeline wiring area to prevent the laminated board from cracking during hoisting.

(3) During on-site construction, the pipeline should be laid according to the optimized pipeline layout. The pipelines in the wiring area should be standardized, neat and beautiful. After the pipelines are laid, the pipeline wiring area should avoid truss bars, transverse bars and longitudinal bars and place them on the laminated board. lower level. The mesh reinforcement is added to the upper part, which can be Φ4@40mm, the width should not be less than the width of the wiring area, and extend 150mm to both sides. The mesh is just connected to other steel bars as closely as possible to avoid the situation that the thickness of the upper concrete does not meet the requirements of the protective layer.

The fourth step, after the concrete pouring is completed, make a mark in the wiring area to prevent the pipeline from being damaged due to the need to use expansion bolts to drill holes in the later stage.

Taking a specific house type as an example, the layout plan of a certain type of strong current pipeline in Figure 1, Figure 2 is the layout plan of the weak current pipeline of this type, the fire equipment is located in the public area, and the public area is generally the cast-in-place area. Figure 1 and Figure 2 are integrated into a comprehensive map of reserved pre-embedded points (Figure 3). In Figure 3, the line paths are chaotic, and there are many overlapping areas. In order to reduce the intersection of pipelines, all pipelines are routed. As shown in Figure 4, the overlapping areas of pipelines are reduced, and special pipelines are planned for the unavoidable overlapping areas of pipelines. wiring area. The dotted area in Figure 4 is the marked pipeline wiring area. Please refer to Figure 5. The pipelines in the pipeline wiring area are arranged at intervals, and the interval is not less than 2cm. The prefabricated thickness of the pipeline wiring area on the laminated board is reduced by 1-1.5cm to form a groove structure. , add mesh reinforcement below the groove structure, and extend the reinforcement mesh to each side of the pipeline wiring area by 150cm. After pouring concrete, after the concrete pouring is completed, make a mark in the pipeline wiring area to prevent the pipeline from being damaged due to the need to use expansion bolts to drill holes in the later stage.

Finally, it should be noted that: the above enumeration is only the preferred embodiment of the present invention, of course those skilled in the art can make changes and modifications to the present invention, if these modifications and modifications belong to the scope of the claims of the present invention and its equivalent technology within the scope of protection of the present invention.
