Description

Technical Field

[0001] The utility model relates to a waterproof structure for a side wall of a basement in an extremely narrow space. Background Art

[0002] The waterproof structure of the basement side wall is generally designed on the water-facing surface (outside of the side wall), and the main waterproofing membrane is applied on the surface of the reinforced concrete structure of the side wall. Therefore, in actual projects, the construction is arranged after the side wall structure is completed. This structural design, when encountering cramped land space, such as special terrain conditions such as rivers and mountains on the outside, will greatly limit and reduce the distance between the underground retaining structure (retaining piles, etc.) and the side wall of the basement. When the size of the space is less than 1 meter, the side wall waterproofing structure implemented later lacks the corresponding working space (laying membranes, painting), further affecting the performance of the waterproof structure and reducing the overall waterproof tightness of the basement. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a waterproof structure for the side wall of a basement in an extremely narrow space with a reasonable structural design, which is convenient for construction workers to operate in an extremely narrow space and has a good waterproof effect.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: a waterproof structure of the side wall of a basement in an extremely narrow space, including a waterproof coiled material and a guard pile, characterized in that: it also includes an ALC board, a hanging piece, a connecting angle steel, an embedded part and an angle steel bracket; the embedded part is buried in the guard pile; one end of the connecting angle steel is fixed to the embedded part, and the other end is fixed to the angle steel bracket; the hanging piece is fixed to the outer side of the ALC board; the ALC board is a plurality of pieces, which are laid flat on the angle steel bracket, and the ALC board is fixed to the angle steel bracket by hanging the hanging piece, and two adjacent ALC boards in the horizontal direction are spliced ​​by tongue and groove to form an ALC inner wall, and the waterproof coiled material is fixed to the inner side surface of the ALC inner wall.

[0005] The angle steel bracket of the utility model comprises a vertical angle steel and a horizontal angle steel. The vertical angle steel and the horizontal angle steel are fixed together, and the vertical angle steel is fixed to the connecting angle steel.

[0006] The ALC plate of the utility model is fixed to the transverse angle steel of the angle steel bracket by hanging the hanging piece.

[0007] The waterproof coiled material described in the utility model adopts a self-adhesive polymer modified asphalt waterproof coiled material.

[0008] The utility model backfills the space between the embedded part and the angle steel bracket with plain soil.

[0009] Compared with the prior art, the utility model has the following advantages and effects:

[0010] 1. The utility model uses ALC plates and angle steels to construct and can be pre-processed in the factory, which speeds up the construction time of the basement side walls, effectively saves time costs, shortens the construction period of the underground part, improves the project construction efficiency, and achieves the goals of industrialization and assembly.

[0011] 2. The utility model uses ALC boards as factory prefabricated boards, and the resulting basement exterior wall side walls have better flatness, providing a flatter base surface for pasting waterproof membranes, improving the airtightness between the waterproof membranes and ALC, and thus enhancing the overall waterproof performance of the basement side walls.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0020] The embodiment of the utility model comprises an ALC board 1, a hanging sheet 3, a connecting angle steel 4, a waterproof coiled material 5, a retaining pile 7, an embedded part 8 and an angle steel bracket 9.

[0021] The embedded part 8 is embedded in the retaining pile 7. When the retaining pile 7 is cast, the embedded part 8 can be implanted.

[0022] One end of the connecting angle steel 4 is fixed to the embedded part 8 by welding, and the other end is fixed to the angle steel bracket 9 by cold welding.

[0023] The angle steel bracket 9 comprises a vertical angle steel 91 and a horizontal angle steel 92 . The vertical angle steel 91 and the horizontal angle steel 92 are welded and fixed together. The vertical angle steel 91 is fixed to the connecting angle steel 4 by cold welding.

[0024] The outer side of the 100mm thick ALC board 1 is drilled in the factory by mechanical processing to form a mechanical connection point, and the hanging piece 3 is fixed to the outer side of the ALC board 1 by screws 2. The ALC board 1 is multiple pieces, which are laid flat on the angle steel bracket 9. The installation sequence is from bottom to top. The ALC board 1 is fixed to the horizontal angle steel 92 of the angle steel bracket 9 by hanging the hanging piece 3. The adjacent two ALC boards 1 in the horizontal direction are spliced ​​by tongue and groove to form a flat and stable ALC inner wall.

[0025] A waterproofing membrane 5 is fixed on the inner side of the ALC inner wall. The waterproofing membrane 5 is a self-adhesive polymer modified asphalt waterproofing membrane, forming a flat basement outer wall to facilitate the subsequent construction of the basement side wall 6. The distance between the embedded part 8 and the ALC inner wall filled with the waterproofing membrane 5 is L1, which is less than or equal to 1 meter.

[0026] Finally, the space between the embedded part 8 and the angle steel bracket 9 is backfilled with soil and compacted, with the compaction coefficient being not less than 0.93.

[0027] Through the building structure of this embodiment, when the construction space of the basement side wall 6 is cramped (less than 1 meter) and it is difficult for construction workers to enter it to carry out waterproofing work, the ALC inner wall and waterproof membrane 5 can be constructed first, which can be used as the outer formwork for pouring the side wall concrete, and then the basement side wall can be constructed in the order of construction workers to carry out waterproofing work on the basement side wall.

[0028] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
