Description

Technical Field

[0001] This invention relates to the field of roof leak prevention technology, specifically to a roof expansion joint leak prevention protection structure and prefabricated expansion joint leak prevention components based on architectural design. Background Technology

[0002] Expansion joints are also provided in the roofs of buildings. Expansion joints are a general term encompassing expansion joints, settlement joints, and seismic joints. Buildings often deform under external forces, leading to cracking or even damage. Expansion joints are structural joints designed to address this. To waterproof and protect expansion joints, waterproof protective covers are installed. However, because expansion joints undergo contraction deformation and recovery under external forces, the waterproof protective covers can also deform.

[0003] In existing technologies, waterproof protective covers generally consist of two plates that can move relative to each other. The ends of the plates are fixed to profiles installed on the expansion joint, which allows the waterproof protective cover to protect the expansion joint. At the same time, the waterproof protective cover can also move with the displacement of the expansion joint. During use, although the middle connecting part of the waterproof protective cover can move to adapt to the displacement of the expansion joint, there are gaps in the relatively moving parts in the middle of the waterproof protective cover. These gaps are very likely to cause water leakage. Therefore, we propose a roof expansion joint anti-leakage protection structure and prefabricated anti-leakage components based on building design. Summary of the Invention

[0004] This invention provides a roof expansion joint waterproofing protection structure and prefabricated expansion joint waterproofing components based on architectural design. To solve the technical problem of easy water seepage in the relatively movable part between the two waterproof protective covers, this invention adopts the following technical solution:

[0005] A roof expansion joint waterproofing protection structure based on architectural design is used to cover the expansion joints of the roof wall. It includes a protective device, which includes an integrated protective cover covering the expansion joint, and fasteners installed on both sides of the expansion joint; a transmission mechanism that drives the integrated protective cover to move relative to the fasteners in the vertical direction of the expansion joint displacement; and a waterproof kit for sealing and waterproofing the ends of the moving integrated protective cover.

[0006] Preferably, the fastener includes a support frame and a fixing frame that are fixedly installed on both sides of the expansion joint.

[0007] Preferably, the transmission mechanism includes a transmission plate fixedly disposed at the top of the support frame, and one end of the transmission plate is slidably connected to the integrated protective cover.

[0008] Preferably, the waterproof kit includes a connecting strip and a sealing strip that are interlocked, and a compression spring fixed between the connecting strip and the sealing strip, wherein the connecting strip is fixedly installed at the end of the integrated protective cover.

[0009] Preferably, the waterproof kit includes a mounting plate fixedly installed on the roof wall, and a baffle is provided on the outward-facing side of the mounting plate.

[0010] Preferably, the mounting plate has a movable groove on its inward-facing side, and the end of the transmission plate away from the integrated protective cover abuts against the movable groove.

[0011] A prefabricated expansion joint waterproofing component is installed on a roof wall with an expansion joint, the expansion joint being covered by the aforementioned roof expansion joint waterproofing protection structure.

[0012] As can be seen from the above technical solutions, the present invention has the following beneficial effects:

[0013] 1. By setting an integrated protective cover, which is connected to the support frame through a transmission mechanism, the integrated protective cover is positioned above the expansion joint, support frame, and fixed frame, providing effective waterproofing and protection. Furthermore, when the expansion joint deforms, the integrated protective cover can move relative to the support frame and fixed frame via the transmission mechanism. The integrated protective cover has no seams, avoiding the need for two traditional waterproof protective covers that move relative to each other. Additionally, the waterproof kit provides a water-blocking effect at the ends of the integrated protective cover, resulting in better leak prevention.

[0014] 2. By setting up a compression fixing mechanism, when installing the fixing frame, first place the limit strips on both sides above the expansion joint, and then push the integrated protective cover downward so that the limit strips can be squeezed into the expansion joint through the side slope, driving the compression rod to move into the installation sleeve, compressing the positioning spring, until the limit strip and fixing strip are respectively inserted into the limit groove and fixing groove. At this time, under the action of the positioning spring, the position of the fixing frame is fixed, which improves the convenience and efficiency of installation. Attached Figure Description

[0023] A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] This application provides a roof expansion joint waterproofing protection structure and expansion joint waterproofing prefabricated components based on architectural design, which solves the problem of water leakage at the bolted part connecting the middle connection part of the waterproof protective cover to the waterproof protective cover and the profile.

[0025] like Figure 1 and Figure 2 As shown, a roof expansion joint waterproofing protection structure based on building design is used to cover the expansion joint 101 of the roof wall 10. It includes a protection device 20, which includes an integrated protective cover 201 covering the expansion joint 101 and fasteners 202 installed on both sides of the expansion joint 101. A transmission mechanism 30 drives the integrated protective cover 201 to move relative to the fasteners 202 in the vertical direction of the displacement of the expansion joint 101. A waterproof kit 50 is used to seal and waterproof the ends of the moving integrated protective cover 201.

[0026] The integrated protective cover 201 is located directly above the opening of the expansion joint 101. The integrated protective cover 201 and the fixing member 202 can move relative to each other through the transmission mechanism 30. The fixing member 202 is in contact with the inner wall of the expansion joint 101. The fixing member 202 includes a support frame 2021 and a fixing frame 2022 fixedly installed on both sides of the expansion joint 101. An adhesive strip 2023 is fixedly installed between the two fixing frames 2022. The number of adhesive strips 2023 can be set to multiple. Preferably, one is set at the top and one at the bottom of the fixing frame 2022, or only one is set at the bottom of the fixing frame 2022. The adhesive strip 2023 can play a waterproof sealing role, and also play a buffering and anti-loosening role. The transmission mechanism 30 is set between the support frame 2021 and the integrated protective cover 201.

[0027] As one implementation method of this embodiment, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the transmission mechanism 30 includes a transmission plate 301 fixedly mounted on the top of the support frame 2021. One end of the transmission plate 301 is slidably connected to the integrated protective cover 201. The integrated protective cover 201 has a cavity. One end of the transmission plate 301 extends into the cavity of the integrated protective cover 201 and is slidably connected to the cavity. Preferably, both the cavity and the transmission plate 301 are inclined to ensure that when the expansion joint 101 is displaced, the distance between the integrated protective cover 201 and the expansion joint 101 can change.

[0028] When the expansion joint 101 deforms, the transmission plate 301 will move laterally. The transmission plate 301 can move within the cavity of the integrated protective cover 201. Since both the cavity and the transmission plate 301 are inclined downwards, the relative sliding between the transmission plate 301 and the cavity will pull the integrated protective cover 201 to move vertically.

[0029] As one implementation method of this embodiment, such as Figure 2 , Figure 4 and Figure 6 As shown, the waterproof kit 50 includes a connecting strip 501 and a sealing strip 502 that are interlocked, and a compression spring 503 fixed between the connecting strip 501 and the sealing strip 502. The connecting strip 501 is fixedly installed at the end of the integrated protective cover 201. The two ends of the integrated protective cover 201 are folded downwards, so that the movement between the connecting strip 501 and the sealing strip 502 is perpendicular to the top of the roof wall 10. The bottom of the sealing strip 502 is rounded. When the expansion joint 101 deforms, the integrated protective cover 201 moves vertically. The compression spring 503 uses its own elasticity to keep the sealing strip 502 pressed against the top of the roof wall 10. At the same time, the connecting strip 501 and the sealing strip 502 are interlocked, which effectively improves the sealing and waterproofing effect.

[0030] As one implementation method of this embodiment, such as Figure 2 , Figure 3 As shown, the waterproof kit 50 also includes a mounting plate 504 fixedly installed on the roof wall 10. A baffle 505 is provided on the outward side of the mounting plate 504, that is, the side of the mounting plate 504 away from the expansion joint 101. A moving groove 506 is opened on the inward side of the mounting plate 504. The end of the transmission plate 301 away from the integrated protective cover 201 abuts against the moving groove 506. The mounting plate 504 and the baffle 505 are both embedded in the roof wall 10. When the expansion joint 101 is displaced, the integrated protective cover 201 and the transmission plate 301 interact. The downward tilted side of the transmission plate 301 is in close contact with the inner wall of the moving groove 506. The baffle 505 and the mounting plate 504 are both embedded in the top of the roof wall 10. At the same time, the sealing strip 502 is tightly attached to the roof wall 10 near the baffle 505, which further improves the waterproof sealing effect, making it difficult for rainwater to enter the interior of the expansion joint 101.

[0031] The waterproof kit 50 can also be replaced with a rubber pad, and the rubber pad is opened by a spring or elastic sheet, so that the rubber pad can move with the integrated protective cover 201, and the spring or elastic sheet can press the rubber pad onto the roof wall 10.

[0032] As one implementation method of this embodiment, such as Figures 2-4 As shown, the fixing frame 2022 is fixed to the inner wall of the expansion joint 101 by the compression fixing mechanism 40. The compression fixing mechanism 40 includes a first embedded part 401 and a second embedded part 402 located on the inner wall of the expansion joint 101. The first embedded part 401 and the second embedded part 402 are respectively provided with a limiting groove 4011 and a fixing groove 4021. The side wall of the fixing frame 2022 is respectively fixedly installed with a limiting strip 4012 and a fixing strip 4022 that are interlocked with the limiting groove 4011 and the fixing groove 4021. The first embedded part 401 and the second embedded part 402 are both embedded in the inner wall of the expansion joint 101.

[0033] During the pouring of the roof wall 10, the first embedded part 401 and the second embedded part 402 are embedded in the inner wall of the expansion joint 101. When the integrated protective cover 201 is installed, the limiting strip 4012 and the fixing strip 4022 on the side wall of the fixing frame 2022 are respectively inserted into the limiting groove 4011 and the fixing groove 4021, so that the fixing frame 2022 can be installed on the inner wall of the expansion joint 101.

[0034] Preferably, the limiting strip 4012 is disposed below the fixing strip 4022, and the limiting strip 4012 has an inclined surface.

[0035] As one implementation method of this embodiment, such as Figure 4 and Figure 7 As shown, the compression fixing mechanism 40 also includes a mounting sleeve 403 disposed at the top of the fixing frame 2022. A compression rod 4031 is movably inserted into the inner wall of the mounting sleeve 403. A positioning spring 4032 is disposed between the mounting sleeve 403 and the compression rod 4031. The number of mounting sleeves 403 can be set to multiple. The ends of the mounting sleeves 403 and the compression rod 4031 that are far apart from each other are respectively fixedly connected to the fixing frames 2022 on both sides.

[0036] When installing the fixing bracket 2022, first place the limiting strips 4012 on both sides above the expansion joint 101, and then push the integrated protective cover 201 downward so that the limiting strips 4012 can be squeezed into the expansion joint 101 through the inclined surface, driving the extrusion rod 4031 to move towards the installation sleeve 403 and compress the positioning spring 4032 until the limiting strips 4012 and the fixing strips 4022 are respectively inserted into the limiting grooves 4011 and the fixing grooves 4021. At this time, under the action of the positioning spring 4032, the installation sleeve 403 and the extrusion rod 4031 press the top of the fixing bracket 2022 on both sides through the positioning spring 4032 to realize the installation and improve the convenience of installation.

[0037] The aforementioned roof expansion joint waterproofing structure can be used as a prefabricated component to cover expansion joint 101, thereby improving ease of use.

[0038] In use, the fixing frame 2022 is first installed on the inner wall of the expansion joint 101 using the compression fixing mechanism 40. The specific installation steps are as described above. The support frame 2021 and the fixing frame 2022 are respectively attached to the top of the roof wall 10 and the inner wall of the expansion joint 101. The integrated protective cover 201 is connected to the support frame 2021 through the transmission mechanism 30, so that the integrated protective cover 201 can be fixed above the expansion joint 101, the support frame 2021 and the fixing frame 2022 structure, so that it can play a role in waterproofing and protection. At the same time, the integrated protective cover 201 can move with the displacement of the expansion joint 101.

[0039] When the expansion joint 101 deforms, the integrated protective cover 201 can move relative to the support frame 2021 and the fixing frame 2022 along the vertical direction of the displacement of the expansion joint 101 through the movement between the cavity and the transmission plate 301. The integrated protective cover 201 has no seam in the middle, and the side is equipped with a waterproof kit 50. The compression spring 503 drives the sealing strip 502 to always press against the top of the roof wall 10 through its own elasticity. The downward tilted side of the transmission plate 301 is in close contact with the inner wall of the moving groove 506. The baffle 505 and the mounting plate 504 are pre-embedded in the top of the roof wall 10, effectively replacing the traditional bolt fixing. It is difficult for rainwater from the outside to enter the interior of the expansion joint 101, which can play a better role in preventing leakage.

[0040] The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
