Description

Technical Field

[0001] This utility model relates to a building construction structure in which the distribution box is constructed synchronously with the wall, specifically to a structure for synchronous construction of a distribution box in a reinforced concrete shear wall. Background Technology

[0002] The interior walls of a building include brick walls made of brick and mortar, as well as reinforced concrete shear walls. The reinforced concrete shear walls form the load-bearing system. A shear wall structure refers to a vertical reinforced concrete wall panel, while the horizontal direction is still supported by a large reinforced concrete floor slab, thus forming a shear wall structure.

[0003] Chinese patent document CN113027129A discloses an embedded integrated distribution box and its construction method. This patent involves prefabricating reinforced concrete components for the distribution box and then simultaneously embedding these components into the masonry wall, improving the integrity of the concealed box and the masonry structure. However, the prefabricated reinforced concrete components of this distribution box are only suitable for brick walls and not for reinforced concrete shear wall structures.

[0004] In the construction of reinforced concrete shear walls, the traditional method for installing electrical distribution boxes involves chiseling holes in the wall after construction is complete, and then installing the distribution box within those holes. This secondary construction often results in additional trenching for wiring conduits and relocation of the pre-reserved openings, significantly increasing subsequent chiseling costs and hindering cost reduction and efficiency improvement.

[0005] In view of the above, this utility model is hereby applied for. Utility Model Content

[0006] This utility model provides a construction structure for a reinforced distribution box embedded inside a shear wall. It solves the problem that installing a distribution box in the opening during the construction of concrete shear wall projects, i.e., using a secondary construction distribution box, easily leads to secondary trenching of distribution pipes and displacement of the opening, significantly increasing the cost of subsequent chiseling, and is not conducive to cost reduction and efficiency improvement.

[0007] To solve the above problems, this utility model adopts the following technical solution: a reinforced distribution box construction structure embedded inside a shear wall, including a distribution box body 1 and a concrete shear wall 8, and also including a distribution box reinforcement body 3 and a wiring conduit 4. The distribution box body 1 is surrounded by the distribution box reinforcement body 3. The distribution box reinforcement body 3 formed by concrete pouring is an integral structure with the distribution box body 1. The front opening of the distribution box body 1 is exposed outside the distribution box reinforcement body 3. The distribution box reinforcement body 3 has a conduit hole 31 that communicates with the inside of the distribution box body 1.

[0008] The distribution box reinforcement 3 and the wiring conduit 4 are fixed to the shear wall reinforcement 6. Positioning ribs 5 are provided around the distribution box reinforcement 3. The positioning ribs 5 on the top, bottom, left, right and rear sides of the distribution box reinforcement 3 fix the distribution box reinforcement 3. The positioning ribs 5 are tied together with the shear wall reinforcement 6. The wiring conduit 4 is tied together with the shear wall reinforcement 6, and the end of the wiring conduit 4 is inserted into the port of the conduit hole 31.

[0009] Furthermore, the construction structure of the reinforced distribution box inside the pre-embedded shear wall of this utility model also has the following characteristics: the distribution box reinforcement body 3 covers the top, bottom, left, right and rear sides of the distribution box body 1.

[0010] Furthermore, the construction structure of the reinforced distribution box inside the pre-embedded shear wall of this utility model also has the following characteristics: a distribution box support component 2 is set inside the distribution box reinforcement body 3. The distribution box support component 2 includes a wooden board 21, a support rod 22 and a nut 23. The two wooden boards 21 are respectively set on the inner side of the top and bottom surfaces of the distribution box body 1. At least two support rods 22 are set between the two wooden boards 21. Each support rod 22 is screwed to a nut 23 at both ends. The nut 23 firmly supports the wooden board 21 on the top and bottom surfaces of the distribution box body 1.

[0011] Furthermore, the construction structure of the reinforced distribution box inside the pre-embedded shear wall of this utility model also has the following characteristics: the distribution box reinforcement body 3 has horizontally arranged positioning ribs 5 on its top, the distribution box reinforcement body 3 has vertically arranged positioning ribs 5 on its left and right sides, and the distribution box reinforcement body 3 has horizontally and vertically arranged positioning ribs 5 on its rear side.

[0012] Furthermore, the construction structure of the reinforced distribution box inside the pre-embedded shear wall of this utility model also has the following characteristics: a steel plate 11 is fixed to the edge of the front opening of the distribution box 1, and the steel plate 11 is fixed to the front template of the concrete shear wall 8.

[0013] This utility model relates to a technology for pre-embedding electrical distribution boxes in concrete shear walls. Its technical advantages are as follows:

[0014] 1. Low cost: The distribution box is installed along with the structure in one go, with reasonable technology, simple construction, convenient operation, and easy production and manufacturing of the distribution box and reinforcement.

[0015] 2. Convenient operation: Unlike the traditional secondary installation process of distribution boxes, the distribution box is first fixed by leveling and elevating the concrete wall and column, and then professional personnel are arranged to lay the wiring. During the laying, the wiring must be tied to prevent the wiring from shifting after the concrete is poured. The position is checked and verified to be consistent with the drawings. Finally, the concrete is poured.

[0016] 3. Excellent performance: The distribution box is installed simultaneously during structural construction. The solidified distribution box avoids the tedious construction of pre-embedded wooden boxes, secondary piping and box installation, and secondary trenching at the distribution box location, and saves on material and labor costs.

[0017] 4. Energy-saving and environmentally friendly, with significant economic benefits: Traditional secondary installation of distribution boxes requires not only a large number of pre-embedded wooden boxes, but also formwork removal and secondary trenching and pipe laying, resulting in material waste and potential displacement. This new type of distribution box is constructed synchronously with the structure, making it more energy-efficient and environmentally friendly. It is installed in one go, reducing waste of formwork and pipeline materials, saving resources, and significantly reducing labor and material costs.

[0018] 5. The quality of the project is significantly improved in all aspects compared with the secondary installation of the distribution box. The distribution box body is fixed with positioning ribs according to the design requirements, and is fixed to the shear wall template by the steel plate on the front side of the distribution box body. As a result, the box body is vertical and flat, without protruding from the structural surface or recessed into the structural wall. The appearance quality of the wall also meets the expected effect.

[0026] The present invention will now be described in detail using the preferred embodiments.

[0027] like Figure 1-6As shown, the construction structure of the reinforced distribution box inside the pre-embedded shear wall includes a distribution box body 1 and a concrete shear wall 8. Its characteristic is that it also includes a distribution box reinforcement body 3 and a wiring conduit 4. The distribution box body 1 is surrounded by the distribution box reinforcement body 3, which covers the top, bottom, left, right, and rear sides of the distribution box body 1. The method for preparing the distribution box reinforcement body 3 involves setting a standardized template around the distribution box body 1, then pouring concrete to form the distribution box reinforcement body 3, which is an integral structure with the distribution box body 1. After the concrete dries, the standardized template is removed, thus forming the distribution box reinforcement body 3. The front opening of the distribution box body 1 is exposed outside the distribution box reinforcement body 3. A pipe is also provided on the top of the distribution box body 1, thus forming a conduit hole 31 on the distribution box reinforcement body 3 that communicates with the inside of the distribution box body 1.

[0028] Before the solidification body 3 of the distribution box is poured, a distribution box support assembly 2 is set inside the solidification body 3. The distribution box support assembly 2 includes a wooden board 21, a support rod 22 and a nut 23. The two wooden boards 21 are respectively set on the inner side of the top and bottom surfaces of the distribution box body 1. At least two support rods 22 are set between the two wooden boards 21. Each support rod 22 is screwed to a nut 23 at both ends. The nut 23 firmly supports the wooden board 21 on the top and bottom surfaces of the distribution box body 1.

[0029] Before the concrete shear wall is poured, the distribution box reinforcement 3 and the wiring conduit 4 are fixed to the shear wall reinforcement 6 according to the design position. Positioning ribs 5 are set around the distribution box reinforcement 3. There are horizontal positioning ribs 5 on the top of the distribution box reinforcement 3. There are vertical positioning ribs 5 on the left and right sides of the distribution box reinforcement 3. There are horizontal and vertical positioning ribs 5 on the rear side of the distribution box reinforcement 3. The positioning ribs 5 on the top, bottom, left, right and rear sides of the distribution box reinforcement 3 fix the distribution box reinforcement 3. The positioning ribs 5 are tied together with the shear wall reinforcement 6. The wiring conduit 4 is tied together with the shear wall reinforcement 6, and the end of the wiring conduit 4 is inserted into the port of the conduit hole 31.

[0030] A steel plate 11 is fixed to the edge of the front opening of the distribution box 1. The steel plate 11 is fixed to the front formwork of the concrete shear wall 8. This structure prevents the poured concrete from entering the distribution box 1. After the concrete shear wall 8 is poured, the front opening of the distribution box 1 is flush with the front of the shear wall. At the same time, the position of the distribution box is further fixed to prevent the distribution box from shifting during pouring.

[0031] Compared with existing similar technologies, this utility model has the following characteristics:

[0032] Compared with the secondary installation of distribution boxes, the quality of the project has been significantly improved in all aspects. The distribution box body is fixed with positioning ribs according to the design requirements, and is fixed to the shear wall template by the steel plate on the front side of the distribution box body. As a result, the box body is vertical and flat, neither protruding from the structural surface nor recessed into the structural wall, and the appearance quality has also achieved the expected effect.

[0033] This technology can be widely applied to shear walls, allowing for the installation of electrical distribution boxes in a single construction phase. This saves costs, time, and labor, while also being environmentally friendly. It also increases the construction progress, and the method is convenient, quick, and easy for workers to operate, saving significant amounts of labor and material costs.

[0034] Technical level and technical difficulty (compared with similar technologies within and outside the province):

[0035] The technical difficulty is relatively simple: the distribution box is installed simultaneously with the structural construction. It can be installed in one go as the concrete is poured. The main steps are to first tie the reinforcing steel, then pre-embed the box, and then lay the pipelines and install them at the same time. The installation flatness should be consistent with the wall and column. After the installation is completed, a re-inspection is carried out to prevent positional errors that would cause rework. The technical difficulty is relatively simple.

[0036] Cost savings: The distribution box does not require secondary installation and can be installed simultaneously with the structural construction. This minimizes losses during installation, improves work efficiency, facilitates subsequent construction, and saves on construction costs.

[0037] Technical challenges: After determining the wall and distribution box thickness according to the drawings, the distribution box is pre-embedded. It is necessary to ensure the position of the box and the welding must be firm to prevent displacement during concrete pouring. At the same time, the steel plate on the front of the distribution box is used to fix it to the shear wall formwork to prevent concrete from entering the box during pouring. This further fixes the position of the distribution box and ensures that the front end of the distribution box is flush with the wall surface.

[0038] The enclosure is secured using positioning ribs, which can be welded to the shear wall reinforcement. Accurate positioning must be ensured before welding to avoid rework. A distribution box support assembly is installed inside the enclosure to prevent deformation. The electrical conduits within the enclosure are arranged according to the selected material specifications and number of circuits. The conduits mate with the wiring holes on the upper part of the enclosure, ensuring neat arrangement, one conduit per hole, and a hole spacing of at least 15mm.

[0039] The distribution box was constructed simultaneously with the structure. The application of the construction method that improves quality and efficiency has saved construction time and reduced labor costs. It is environmentally friendly and energy-saving, and has been highly recognized by the construction and supervision units.

[0040] The principle of this technology is as follows: Install and fix the power distribution pipes and the box reinforcement at the designed location to ensure that the box opening is flush with the finished surface of the concrete shear wall structure during installation. At the same time, install and fix the conduit, ensuring that the conduit protrudes 30-50mm from the horizontal surface of the reserved opening in the structure. After the shear wall construction is completed and the installation of the concealed power distribution box and other structural construction is completed, remove the formwork. The support components inside the power distribution box can only be installed after the concrete mortar has solidified.
