Description

Technical Field

[0001] The present application relates to the field of expansion joint waterproofing, and in particular to an expansion joint waterproofing structure. Background Art

[0002] Large roof slabs are usually left with expansion joints after the main construction is completed, so that the main building is not easily damaged by temperature difference or settlement. The expansion joints need to meet the needs of deformation and displacement of the main building on the one hand, and waterproofing needs on the other.

[0003] In the existing related technologies, the waterproofing of the expansion joint is generally achieved by elastic parts and cover plates. For example, Chinese utility model CN ​​220266866 U is a waterproof building indoor floor expansion joint component, which inserts two plywood into the expansion joint so that the waterproof cover plate can be quickly installed on the floor.

[0004] With regard to the above-mentioned related technologies, the inner wall of the expansion joint is affected by the construction process, and the inner wall of the expansion joint will inevitably have more gaps, which makes it easy for gaps to form between the plywood and the inner wall of the expansion joint, allowing rainwater to penetrate into the expansion joint through the gaps, causing water seepage in the floor slab. Summary of the invention

[0005] In order to prevent rainwater from penetrating into the expansion joint, the present application provides a expansion joint waterproof structure.

[0006] The present application provides a deformation joint waterproof structure adopting the following technical solution:

[0008] The waterproof cover plate comprises a bent plate body and a connecting plate body, the bent plate body is plugged into the deformation joint, the bent plate body is bent to form a cover plate groove, the notch of the cover plate groove is arranged upward, and the cover plate groove extends along the length direction of the deformation joint, and the bent plate body is elastic; the connecting plate body is connected to the bent plate body, and the connecting plate body is installed on the roof floor;

[0009] The bent plate body is provided with abutting rubber pads, and two sides of the abutting rubber pads are respectively tightly matched with two inner walls of the deformation joint.

[0010] By adopting the above technical solution, the two sides of the abutting rubber pad are respectively tightly matched with the two inner walls of the deformation joint, reducing the gap between the bent plate body and the inner wall of the deformation joint, thereby making it difficult for rainwater to penetrate into the deformation joint. In addition, the deformation joint is waterproofed by the bent plate body and the connecting plate body, and the structure is simple, and it is not easy to be damaged by rain, sunlight and strong wind on the roof.

[0011] Optionally, the connecting plate body is installed with a connecting cover plate, and the cover plate groove is located in the area covered by the connecting cover plate.

[0012] By adopting the above technical solution, the cover plate is connected to cover the cover plate groove, so that water is not easy to accumulate in the cover plate groove, thereby reducing the occurrence of damage to the bent plate body due to water load caused by excessive water accumulation in the cover plate groove.

[0013] Optionally, the cross-section of the connecting cover plate is arc-shaped, and the connecting cover plate is inclined from top to bottom in a direction away from the deformation joint.

[0014] By adopting the above technical solution, rainwater flows along the connecting cover plate to the roof floor, making it difficult for water to accumulate on the top of the connecting cover plate, thereby reducing the occurrence of excessive water accumulation causing water to seep into the cover plate groove from the installation gap between the connecting cover plate and the connecting plate body.

[0015] Optionally, the connecting plate body is provided with a snap-in groove, the connecting cover plate is snap-fitted into the snap-in groove, and the connecting cover plate is elastic.

[0017] Optionally, a drain pipe is provided in the cover plate groove, an input end of the drain pipe is connected to the cover plate groove, and the other end of the drain pipe is connected to an external drainage system.

[0018] By adopting the above technical solution, rainwater that penetrates into the cover plate groove from the installation gap between the connecting plate body and the connecting cover plate is discharged to the external drainage system through the drain pipe, further reducing the occurrence of damage to the bent plate body due to water load caused by excessive water accumulation in the cover plate groove.

[0019] Optionally, the drain pipe is arranged near the end of the cover plate groove, and the input end of the drain pipe is plugged with a water-guiding fiber rope, and the water-guiding fiber rope is arranged along the extension direction of the cover plate groove.

[0020] By adopting the above technical solution, rainwater that penetrates into the cover plate groove from the installation gap between the connecting plate body and the connecting cover plate is absorbed by the water-guiding fiber rope and then transported to the drain pipe. On the one hand, it reduces the workload of laying the drain pipe, and on the other hand, it is also convenient to transport a small amount of accumulated water in the cover plate groove to the drain pipe in a timely manner.

[0021] Optionally, a reinforcing steel mesh is embedded inside the bent plate body.

[0022] By adopting the above technical solution, the steel wire mesh ensures the structural strength of the bent plate body, so that the bent plate body is not easily damaged by rain, sunlight and strong wind on the roof.

[0023] Optionally, a sealant is provided on one side of the connecting plate body away from the bent plate body, and two sides of the sealant are respectively bonded to the connecting plate body and the roof floor.

[0024] By adopting the above technical solution, the sealant makes it difficult for rainwater to penetrate into the deformation joint from the gap between the connecting plate body and the roof floor.

[0027] By adopting the above technical solution, on the one hand, the waterproof base plate covers the deformation joint to ensure the aesthetics of the bottom of the roof floor, and on the other hand, it makes it difficult for rainwater that penetrates into the deformation joint to penetrate into the room.

[0028] Optionally, the waterproof bottom plate is provided with a bending portion.

[0029] By adopting the above technical solution, the waterproof bottom plate with a bending portion is more likely to deform accordingly with the deformation and displacement of the building body, thereby reducing the occurrence of breakage due to the waterproof bottom plate being too rigid to adapt to the deformation and displacement of the building body.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. The two sides of the abutting rubber pad are respectively tightly fitted to the two inner walls of the deformation joint, reducing the gap between the bent plate body and the inner wall of the deformation joint, thereby preventing rainwater from penetrating into the deformation joint. In addition, the deformation joint is waterproofed by the bent plate body and the connecting plate body, which has a simple structure and is not easily damaged by rain, sunlight and strong wind on the roof.

[0032] 2. The cover plate is connected to cover the cover plate groove, so that water is not easy to accumulate in the cover plate groove, thereby reducing the occurrence of damage to the bent plate body due to water load caused by excessive water accumulation in the cover plate groove.

[0033] 3. Rainwater that penetrates into the cover plate groove from the installation gap between the connecting plate body and the connecting cover plate is discharged to the external drainage system through the drainage pipe, further reducing the occurrence of damage to the bent plate body due to water load caused by excessive water accumulation in the cover plate groove.
