Description

Technical Field

[0001] The utility model relates to the technical field of roof leakage prevention, in particular to a deformation joint waterproof device. Background Art

[0002] Expansion joint waterproofing devices are used to prevent leakage at the expansion joints of buildings. In various structures of buildings, expansion joints are prone to occur due to temperature changes and other reasons. Expansion joint waterproofing devices are usually made of waterproof materials and have a certain degree of flexibility and scalability. If these expansion joints are not effectively waterproofed, they will cause leakage in the building. In order to solve this problem, people have developed expansion joint waterproofing devices.

[0003] In the prior art, the waterproof protective cover is generally composed of two plates that can be displaced with each other, and the plates are connected to the profile installed on the deformation joint by bolts, so that the waterproof protective cover can protect the deformation joint, and the waterproof protective cover can also move with the displacement of the deformation joint. However, during the use of the above scheme, since the end of the plate is fixed to the profile of the deformation joint by bolts, the pressing method of the bolts causes the plate to not fit tightly with the profile at the deformation joint, resulting in water seepage on the side of the waterproof protective cover. Therefore, we propose a deformation joint waterproof device. Utility Model Content

[0004] In order to solve the above technical problems, the utility model solves the problem that the plate body and the profile at the deformation joint are not tightly fitted due to the pressing method of the bolts, resulting in easy water seepage on the side of the waterproof protective cover. The specific technical solution is as follows:

[0005] A deformation joint waterproof device is used to cover the deformation joint of a roof wall, comprising a protective component, the protective component comprising a waterproof cover covering the deformation joint; a leak-proof component is used to seal and waterproof the gap between the end of the waterproof cover and the roof wall; the leak-proof component comprises a side strip and a water-blocking strip which are sleeved on each other and a spring fixed between the side strip and the water-blocking strip, and the side strip is fixedly installed on the end of the waterproof cover.

[0006] Preferably, the anti-leakage component further comprises a fixing plate fixedly mounted on the roof wall, and a side plate is provided on the outward side of the fixing plate.

[0007] Preferably, the side panels and the fixing panels are both pre-embedded in the roof wall.

[0008] Preferably, the protective component further includes a mounting piece installed on the inner wall of the deformation joint, and the waterproof cover is connected to the mounting piece.

[0009] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0010] As the expansion joint moves, the waterproof cover moves in the vertical direction of the expansion joint. If the waterproof cover moves toward the roof wall, the side strip compresses the spring, and the spring drives the water-blocking strip to press and seal the gap between the end of the waterproof cover and the roof wall. If the waterproof cover moves away from the roof wall, the bottom of the water-blocking strip always contacts the roof wall under the action of the spring, that is, no matter how the waterproof cover moves, the gap between the waterproof cover and the roof wall is always sealed and waterproofed. Because the downwardly inclined side of the guide plate contacts the inner wall of the positioning groove tightly, and the side plate and the fixing plate are pre-embedded in the top of the roof wall, a further waterproof sealing effect is achieved, and it is difficult for rainwater from the outside to enter the expansion joint, further improving the sealing effect.

DETAILED DESCRIPTION

[0018] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0019] like Figure 1 and Figure 2As shown, a deformation joint waterproof device is used to cover the deformation joint 101 of the roof wall 10, including a protective component 20, the protective component 20 includes a waterproof cover 201 covering the deformation joint 101; the anti-leakage component 40 is used to seal the gap between the end of the waterproof cover 201 and the roof wall 10 for waterproofing;

[0020] Among them, the waterproof cover 201 is located directly above the opening of the deformation joint 101, and the waterproof cover 201 and the mounting member 202 can move relative to each other through the transmission component 30, and the mounting member 202 is in contact with the inner wall of the deformation joint 101; the mounting member 202 includes a connecting frame 2021 and a mounting frame 2022 fixedly installed on both sides of the deformation joint 101, and a rubber strip 2023 is fixedly installed between the two mounting frames 2022, wherein the number of rubber strips 2023 can be set in multiples, and preferably one is set at the top and bottom of the mounting frame 2022, or only one is set at the bottom of the mounting frame 2022, and the rubber strip 2023 can play a waterproof and sealing effect, and also plays a buffering and anti-loosening effect, and the transmission component 30 is arranged between the connecting frame 2021 and the waterproof cover 201.

[0021] As an implementation method of this embodiment, Figure 1-Figure 4 As shown, a transmission component 30 is arranged between the connecting frame 2021 and the waterproof cover 201, and they move relatively through the transmission component 30. The transmission component 30 includes a guide plate 301 fixedly arranged on the top of the connecting frame 2021, and one end of the guide plate 301 is slidably connected to the waterproof cover 201; wherein, a cavity is arranged on the waterproof cover 201, and one end of the guide plate 301 extends into the cavity of the waterproof cover 201 and is slidably connected to the cavity. Preferably, the cavity and the guide plate 301 are both inclined to ensure that when the deformation joint 101 is displaced, the distance between the waterproof cover 201 and the deformation joint 101 can be driven to change.

[0022] When the deformation joint 101 is deformed, the guide plate 301 will move laterally. The guide plate 301 can move in the cavity of the waterproof cover 201. Since the cavity and the guide plate 301 are both tilted downward, the relative sliding between the guide plate 301 and the cavity will pull the waterproof cover 201 to move vertically.

[0023] As an implementation method of this embodiment, Figure 1 , Figure 3-Figure 5As shown, the leakage-proof component 40 includes a side strip 401 and a water-blocking strip 402 which are sleeved with each other, and a spring 403 fixed between the side strip 401 and the water-blocking strip 402. The side strip 401 is fixedly mounted on the end of the waterproof cover 201; wherein, both ends of the waterproof cover 201 are folded downward so that the movement between the side strip 401 and the water-blocking strip 402 is perpendicular to the top of the roof wall 10, and the bottom of the water-blocking strip 402 is rounded. When the deformation joint 101 is deformed, the waterproof cover 201 moves in the vertical direction. The spring 403 drives the water-blocking strip 402 to always press against the top of the roof wall 10 through its own elastic force. At the same time, the side strip 401 and the water-blocking strip 402 are sleeved with each other, thereby effectively improving the sealing and waterproofing effect.

[0024] As an implementation method of this embodiment, Figure 1 , Figure 3 and Figure 6 As shown, the leakage-proof component 40 also includes a fixing plate 404 fixedly mounted on the roof wall 10, and a side plate 405 is provided on the outward side of the fixing plate 404, that is, the side of the fixing plate 404 away from the deformation joint 101, and a positioning groove 406 is provided on the inward side of the fixing plate 404, and the end of the guide plate 301 away from the waterproof cover 201 is against the positioning groove 406, and the fixing plate 404 and the side plate 405 are both pre-embedded and embedded in the roof wall 10, wherein, when the deformation joint 101 is displaced, the waterproof cover 201 interacts with the guide plate 301, and the side of the guide plate 301 tilted downward is tightly against the inner wall of the positioning groove 406, and the side plate 405 and the fixing plate 404 are both pre-embedded and embedded in the top of the roof wall 10, and at the same time, combined with the water-blocking strip 402, they are tightly fitted with the roof wall 10 near the side plate 405, thereby further improving the waterproof sealing effect, and it is difficult for rainwater from the outside to enter the interior of the deformation joint 101.

[0025] As an implementation method of this embodiment, Figure 2-Figure 4 As shown, the mounting frame 2022 is fixed to the inner wall of the deformation joint 101, preferably by means of a snap-fit ​​installation, which improves the convenience of installation.

[0026] When in use, firstly install the mounting frame 2022 on the inner wall of the deformation joint 101, the connecting frame 2021 and the mounting frame 2022 are respectively fitted with the top of the roof wall 10 and the inner wall of the deformation joint 101, and the waterproof cover 201 is connected to the connecting frame 2021 through the guide plate 301, so that the waterproof cover 201 can be fixed on the top of the deformation joint 101, the connecting frame 2021 and the mounting frame 2022 structure, so that it can play a role of waterproofing and protection, and the waterproof cover 201 can move with the displacement of the deformation joint 101;

[0027] When the deformation joint 101 is deformed, the waterproof cover 201 can move between the cavity and the guide plate 301, so that the waterproof cover 201 moves relative to the connecting frame 2021 and the mounting frame 2022 along the vertical direction of the displacement of the deformation joint 101. The spring 403 drives the water-blocking strip 402 to always press against the top of the roof wall 10 through its own elastic force. The side plate 405 and the fixing plate 404 are pre-embedded in the top of the roof wall 10. The downwardly inclined side of the guide plate 301 is in close contact with the inner wall of the positioning groove 406, which effectively replaces the traditional bolt fixing. It is difficult for rainwater from the outside to enter the interior of the deformation joint 101, which can play a better role in preventing leakage.

[0028] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
