Description

Technical Field

[0001] The utility model relates to the building waterproof technology, in particular to a waterproof structure for expansion joints. Background Technique

[0002] An expansion joint refers to a structural joint provided at an appropriate position along the construction joint direction of a building or structure to prevent cracks or damage to the structure caused by thermal expansion and contraction of building components due to climate temperature changes. The expansion joint divides the building components above the foundation, such as walls, floors, roofs, etc., into two independent parts, enabling horizontal expansion in the extended direction of the building or structure. In a building wall, a waterproof structure needs to be provided at a position corresponding to the expansion joint of the building wall to prevent water leakage and seepage.

[0003] Currently, when waterproofing expansion joints, structures such as stainless steel are usually used. However, during actual use, loosening is likely to occur at the connection when the building expands and contracts, easily resulting in water leakage and seepage. At the same time, it cannot block the water that seeps back, the waterproof effect is poor, and effective waterproof work cannot be carried out. Therefore, we provide a waterproof structure for expansion joints. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the above background technique and provide a waterproof structure for expansion joints. By placing a support plate in the expansion joint, the second electric telescopic rod drives the cross plate and the sealing pad to move to one side, making one side of the sealing pad fit with one side of the gap, and driving the waterproof belt to extend. The waterproof belt blocks the water at one end, and the sealing pad prevents water from penetrating, which can effectively avoid the phenomenon of water leakage and seepage, can effectively block the water that seeps back, has a good waterproof effect, and can effectively carry out waterproof work.

[0005] A waterproof structure for expansion joints provided by the utility model includes a support plate arranged along the direction of the expansion joint. At the bottom and top of both sides of the support plate, multiple second electric telescopic rods perpendicular to the plate surface of the support plate are respectively provided.

On the top of the sealing pad at the top of the support plate, a waterproof belt is provided with one side connected to it and the other side connected to the top of the support plate. On the bottom of the sealing pad at the bottom of the support plate, a waterproof belt is provided with one side connected to it and the other side connected to the bottom of the support plate. Waterproof belts are symmetrically provided at the bottom and top of both sides of the support plate.

[0006] In the above technical solution, a plurality of first electric telescopic rods perpendicular to the plate surface of the support plate are respectively provided in the middle of both sides of the support plate. The first electric telescopic rods on each side of the support plate are located on the same horizontal plane. A fixing plate parallel to the support plate is provided at the end of the first electric telescopic rod on the same side of the support plate away from the support plate.

[0007] In the above technical solution, a rubber pad is provided on the surface of the fixing plate away from the support plate.
