Description

Technical Field

[0001] The invention belongs to the technical field of building construction, and particularly relates to a two-layer casting construction structure and a construction method for pre-installing a strong and weak current box. Background Art

[0002] At present, the conventional installation method of strong and weak current boxes is to embed the strong and weak current boxes into the masonry wall or pre-buried in the precast concrete blocks and then built on the wall, and then groove and embed the corresponding upper and lower connecting pipelines, and finally use mortar to plaster and seal and fix. This construction method usually makes the wall easy to hollow when the pipelines are dense, and it is difficult to shape during plastering, and it is not easy to ensure the construction quality. Summary of the invention

[0003] The object of the present invention is to provide A two-layer pouring construction structure and construction method for the advance installation of strong and weak electricity boxes solves the problems of time-consuming and labor-intensive grooving when there are many pipelines at the installation location of the strong and weak electricity boxes, the easy hollowing of the wall when the pipelines are dense, and the difficulty in shaping during plastering, making it difficult to ensure the construction quality.

[0004] To achieve the above object, the present invention adopts the following technical solution: A two-layer pouring construction structure for pre-installing a strong and weak current box comprises a wall, an upper beam or plate is arranged above the wall, and a lower beam or plate is arranged below the wall; The thickness of the wall is 200mm. A vertical through-going installation groove is opened on the front side of the wall. The thickness of the installation groove is 100mm. The thickness of the wall behind the installation groove is 100mm, forming an installation back wall. The installation slot is equipped with a strong and weak current box and internal pipelines. The four corners of the strong and weak current box are fixed to the installation back wall by screws, and the internal pipelines are connected to the threading tube; Reserved pipes are reserved on the upper beams or plates and the lower beams or plates, and the upper and lower parts of the threading pipes are connected with the reserved pipes through pipe joints; The installation groove and the front side of the wall are closed by formwork, and concrete is poured in the installation groove.

[0005] A further preferred technical solution: the wall is a masonry wall or a concrete wall.

[0006] A further preferred technical solution: the template is a wooden template.

[0007] The construction method of the strong and weak current box installed in advance is divided into two layers of pouring construction structure, and the steps are: Step 1: Wall layout and positioning; Determine the masonry position of the wall, the thickness of the wall is 200mm, and ensure that the wall can wrap the strong and weak electric boxes and internal pipelines; Step 2: wall construction; Determine the pre-installation position of the strong and weak electricity boxes and internal pipelines. When the wall is built to the pre-installation position of the strong and weak electricity boxes and internal pipelines, within the reserved width of the strong and weak electricity boxes and internal pipelines, only the 100mm thick part on the rear side is built to form the installation back wall, and the 100mm thick part on the front side forms the installation groove; Step 3: Install the strong and weak current boxes and internal pipelines; Install the strong and weak current boxes and internal pipelines in the installation slot, and ensure that the strong and weak current boxes are embedded in the installation back wall; Step 4: Support the formwork on one side; Set up the formwork at the installation groove position on the front side of the masonry wall and seal the formwork; Step 5: pouring concrete; After the formwork is set up, fine stone concrete is used to cast densely in the installation groove space. When the pipelines are dense and the fine stone concrete is difficult to cast densely, cement slurry can be used for pouring. The strong and weak electricity boxes and internal pipelines are cast into one through concrete to form a structural column. After the pouring is completed, ensure that the concrete poured later in the installation groove is anchored and embedded with the 100mm thick masonry wall built first.

[0008] Compared with the prior art, the present invention has the following characteristics and beneficial effects: 1. The present invention integrally casts the internal pipelines and the strong and weak electricity boxes into the wall, thereby ensuring the integrity of the wall surface, the molding quality of the finished surface and the integrity of the internal pipeline fixation. The invention has good integrity, is easy to control the quality, is not prone to hollowing, and is suitable for the construction and installation of the electric box and the electric box pipeline in the residence.

[0009] 2. When the wall thickness is 200mm, the present invention adopts a two-layer construction method in which half of the wall thickness is built by masonry and the other half is cast in situ. At the location of the strong and weak current boxes, the 200mm thick wall is divided into a 100mm thick wall and built in advance by masonry. The other 100mm thick wall is sealed on one side and cast with cement slurry after the internal pipelines are installed and arranged; the overall molding quality after the internal pipelines and strong and weak current boxes are installed is ensured.
