Description

Technical Field

[0001] This utility model belongs to the field of building waterproofing technology, and in particular relates to a protective structure for waterproofing layers of underground walls in buildings. Background Technology

[0002] In traditional basement exterior wall construction, a waterproof layer is typically first constructed on the outer side of the wall using SBS waterproof membrane or similar materials. Then, a flexible protective layer of extruded polystyrene (XPS) board is applied over this waterproof layer. Finally, a rigid protective layer is formed by laying hard bricks, such as shale bricks, on the outside of the XPS board. The toughness of the XPS board and the strength of the shale bricks protect the waterproof material from damage. This traditional method requires a large amount of brickwork, resulting in a long construction period, high labor input, and a risk of collapse if the bricks are laid too high. Furthermore, the large number of bricks laid can easily deform or damage the XPS board, leading to damage to the waterproof layer and causing leaks in the basement exterior walls. Adding a cast-in-place concrete strip in the middle of the brick wall to increase its strength would significantly increase construction costs. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a protective structure for the waterproof layer of the underground wall of a building, which can overcome the problems of long construction period, large amount of labor input, easy collapse when the masonry is too high, and easy damage to the waterproof layer in the existing structure.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A waterproof layer protection structure for underground walls of a building includes a wall and a backfill layer. A waterproof layer is provided on the outer wall surface of the wall. A waterproof layer protective board is provided between the waterproof layer and the backfill layer. The waterproof layer protective board includes an extruded polystyrene board and an outer protective board that are tightly bonded together. The extruded polystyrene board is placed between the waterproof layer and the outer protective board.

[0005] The following are further optimizations of the above technical solution by this utility model: The extruded polystyrene board and the outer protective panel are fixedly connected together by multiple connectors.

[0006] Further optimization: The connector is a glass wool insulation nail, which includes an integrally fixed disc part and a nail part, and a fixing piece is fitted on the nail part.

[0007] Further optimization: A concrete adhesive layer is provided on the side of the disc closest to the waterproof layer.

[0008] Further optimization: The outer protective panel is made of PP honeycomb panel.

[0009] This utility model's structure, through rational design, uses a protective board instead of brick masonry, effectively avoiding the problems of long construction cycles, high labor input, and the risk of collapse due to excessively high masonry. Furthermore, the extruded polystyrene (XPS) board and the protective board are tightly bonded together, with the protective board effectively protecting the XPS board and preventing deformation or damage that could compromise the waterproof layer. Additionally, the protective board provides better insulation, achieving energy conservation and emission reduction, and preventing condensation on the inner wall due to temperature differences. The XPS board and protective board are fixed together using barbs and fixing plates on the disc and adhesive nail sections to form the waterproof layer protective board, which is then fixed onto the waterproof layer, providing effective protection. Moreover, the glass wool insulation adhesive nails are standard components, resulting in extremely low usage costs.

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the overall structure of an embodiment of the present utility model; Figure 2 for Figure 1 Enlarged structural diagram at point A; Figure 3 This is a schematic diagram of the connecting member in an embodiment of the present utility model.

[0012] In the diagram: 1-wall; 2-waterproof layer; 3-extruded polystyrene board; 4-outer protective board; 5-connector; 501-disc part; 502-glue nail part; 5021-barbed block; 503-fixing plate; 6-backfill layer. Detailed Implementation

[0013] like Figure 1-3 As shown, a waterproof layer protection structure for an underground wall of a building includes a wall 1 and a backfill layer 6. A waterproof layer 2 is provided on the outer wall surface of the wall 1. A waterproof layer protective board is provided between the waterproof layer 2 and the backfill layer 6. The waterproof layer protective board includes an extruded polystyrene board 3 and an outer protective board 4 that are tightly bonded together. The extruded polystyrene board 3 is provided between the waterproof layer 2 and the outer protective board 4.

[0014] This design uses an outer protective panel 4 instead of a brick wall, effectively avoiding the problems of long construction cycles, large labor input, and easy collapse due to excessive brick masonry. Furthermore, the extruded polystyrene board 3 and the outer protective panel 4 are tightly bonded together, and the outer protective panel 4 provides effective protection for the extruded polystyrene board 3, preventing deformation or damage to the extruded polystyrene board 3, which could lead to the destruction of the waterproof layer 2. In addition, the waterproof layer protective panel has better thermal insulation, achieving energy conservation and emission reduction, and also preventing condensation on the inner wall of the wall 1 due to temperature differences between the inside and outside.

[0015] The outer protective panel 4 can be made of materials with a certain strength, such as plastic panels or wood panels, with PP honeycomb panels being the preferred choice.

[0016] The extruded polystyrene board 3 and the outer protective board 4 are fixedly connected together by multiple connectors 5.

[0017] This design allows for the pre-construction fixing of the extruded polystyrene board 3 and the outer protective board 4 together with connectors 5 to form a waterproof protective layer, which is then fixed as a whole onto the waterproof layer 2, greatly improving construction efficiency.

[0018] In addition to this embodiment, the extruded polystyrene board 3 and the outer protective board 4 can also be glued together with adhesive.

[0019] The connector 5 is a glass wool insulation adhesive nail, which is existing technology and can be purchased from the market. It includes an integrally fixed disc part 501 and an adhesive nail part 502. The adhesive nail part 502 is provided with multiple barbs 5021, and a fixing piece 503 is sleeved on the adhesive nail part 502.

[0020] A concrete adhesive is applied to the side of the disc portion 501 near the waterproof layer 2, forming a concrete adhesive layer between the disc portion 501 and the waterproof layer 2.

[0021] This design significantly reduces the amount of concrete bonding mortar used compared to applying it to the surface of the extruded polystyrene board, and the bonding effect is also better.

[0022] In use, first, through holes are drilled on the aligned extruded polystyrene board 3 and outer protective board 4. The glue nail part 502 passes through the through holes on the extruded polystyrene board 3 and outer protective board 4. The disc part 501 is located on the side of the extruded polystyrene board 3 away from the outer protective board 4. The fixing piece 503 and the glue nail part 502 are snapped together by the barb block 5021, so as to facilitate the connection of the extruded polystyrene board 3 and the outer protective board 4 together to form a waterproof protective board. Then, the waterproof protective board is fixed on the waterproof layer 2 to form effective protection for the waterproof layer 2. Moreover, the glass wool insulation glue nail is a standard part, with extremely low usage cost, which greatly reduces the production cost. Finally, the backfill soil is filled in.

[0023] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
