Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a waterproof structure for the connection parts of the exterior walls of prefabricated buildings. Background Technology

[0002] Prefabricated buildings refer to buildings where a large amount of on-site work in traditional construction methods is transferred to factories. Building components and accessories are processed and manufactured in factories, transported to the construction site, and assembled on-site using reliable connection methods. After two walls are assembled, there will be certain gaps, which are prone to water seepage and leakage. Therefore, waterproof structures are required.

[0003] Patent CN217782415U discloses the following: A waterproof structure for the connection of prefabricated building exterior walls, comprising a first exterior wall and a second exterior wall, which are vertically arranged. Both the first and second exterior walls have T-shaped grooves, with sealing blocks installed within the T-shaped grooves. The sealing blocks have T-shaped mounting grooves, and connecting components are installed within the T-shaped mounting grooves. The two connecting components are sealed together by a protective cover. An absorbent sponge is installed inside the protective cover. End caps are installed at both the top and bottom of the protective cover, sealingly connecting the top and bottom of the protective cover to the first and second exterior walls. This structure can seal the connection between the two assembled wall sections, improving waterproofing. The structure is simple, practical, and easy to install and maintain.

[0004] This patent uses a protective cover to seal the connection and an absorbent sponge to absorb water. However, the protective cover is completely sealed, making it impossible to inspect and repair the internal structure, which is inconvenient to use. Therefore, a waterproof structure for the connection of the exterior wall of a prefabricated building is proposed to solve the above-mentioned problems. Utility Model Content

[0010] In one embodiment, the slide block has a limiting channel communicating with the sliding channel, and a limiting block is fixed to the back of the sliding rod. The limiting block is slidably connected to the slide block through the limiting channel.

[0011] In one embodiment, a bearing is fixed on the inner wall of the bottom of the sealing box, and the threaded rod is rotatably connected to the sealing box through the bearing.

[0012] In one embodiment, both the sealing box and the wall are L-shaped structures, and the back of the sponge board is attached to the back of the wall.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0017] The waterproof structure at the connection points of the prefabricated building's exterior walls utilizes a lifting mechanism to move the movable blocks up and down, thereby driving the cleaning blocks and sponge boards to move and clean, thus waterproofing the connection points and improving the structure's waterproofing effect. The switch components facilitate the opening and closing of the sealed box, enabling quick inspection and maintenance of the internal structure, resulting in high ease of use.

[0018] 2. The lifting mechanism provides kinetic energy for the movement of the movable blocks, which in turn drives the cleaning blocks and sponge boards to slide and move, thus enabling protective treatment at the structural joints and improving the waterproofness of the structure.

[0030] Example 1

[0031] Please see Figures 1 to 3 The waterproof structure of the connection part of the exterior wall of the prefabricated building in this embodiment includes a wall 1, a sealing box 2 fixed on the front of the wall 1, both the sealing box 2 and the wall 1 are L-shaped structures, and the front of the wall 1 is provided with a lifting mechanism that is slidably connected to the sealing box 2.

[0032] The lifting mechanism provides kinetic energy for the movement of the movable block 7, which in turn drives the cleaning block 11 and the sponge board 13 to slide and move, thus enabling protective treatment at the structural connection and improving the waterproofness of the structure.

[0033] It is understandable that a switch assembly 10 is provided on the right side of the sealed box 2, and a cleaning block 11 that extends through to the back of the wall 1 is fixed on the lifting mechanism. A sponge board 13 is fixed on the back of the cleaning block 11, and the back of the sponge board 13 is attached to the back of the wall 1. A stabilizing block 12 is fixed on the back of the sponge board 13.

[0034] The switch assembly 10 facilitates the opening and closing of the cover, which in turn facilitates the inspection and maintenance of the structure inside the sealed box 2, thereby improving the stability of the structure and the ease of use.

[0035] Example 2

[0036] Please see Figures 1 to 3 The waterproof structure of the connection part of the exterior wall of the prefabricated building in this embodiment includes a wall 1, a sealing box 2 fixed on the front of the wall 1, both the sealing box 2 and the wall 1 are L-shaped structures, and the front of the wall 1 is provided with a lifting mechanism that is slidably connected to the sealing box 2.

[0037] The lifting mechanism includes a drive motor 3 fixed to the front of the wall 1. The output shaft of the drive motor 3 is fixed with a drive gear 4. The drive gear 4 meshes with a driven gear 5. A threaded rod 6, which is rotatably connected to the sealing box 2, is fixed at the shaft center at the bottom of the driven gear 5. A bearing is fixed on the inner wall of the bottom of the sealing box 2.

[0038] It is also understandable that by setting up the bearing, it is beneficial to realize the rotational connection between the bearing and the threaded rod 6, thereby improving the stability of the rotation of the threaded rod 6 and the stable use of the overall structure.

[0039] It should be noted that the threaded rod 6 is rotatably connected to the sealing box 2 via a bearing. The outer side of the threaded rod 6 is threadedly connected to a movable block 7. The back of the movable block 7 is fixed to the cleaning block 11. Connecting plates 8 are fixed on both the left and right sides of the movable block 7. Sliding rods 9 that are slidably connected to the sealing box 2 are fixed on the opposite sides of the two connecting plates 8. Two sliding seats are fixed on the front of the wall 1.

[0040] Example 3

[0041] This embodiment is a further optimization based on embodiment 2, specifically:

[0042] The sliding block helps to limit the sliding rod 9, which in turn helps to limit the lifting and lowering of the movable block 7, thus facilitating the stable lifting and lowering of the movable block 7 and improving the overall structural stability.

[0043] It should also be noted that a sliding channel is provided on the front of the slide block, and the sliding rod 9 is slidably connected to the slide block through the sliding channel. A limiting channel communicating with the sliding channel is provided on the slide block, and a limiting block is fixed on the back of the sliding rod 9. The limiting block is slidably connected to the slide block through the limiting channel.

[0044] In this embodiment, the setting of sliding channel and limiting channel is conducive to the stable sliding of sliding rod 9, thereby improving the overall structural stability.

[0045] Example 4

[0046] This embodiment is a further optimization based on embodiment 3, specifically:

[0047] Please see Figure 4 To improve ease of use, the switch assembly 10 in this embodiment includes a rotating seat 1001 that is rotatably connected to the right side of the sealed box 2. A sliding plate 1002 is slidably connected to the right side of the rotating seat 1001. A moving channel is provided on the right side of the rotating seat 1001. The sliding plate 1002 is slidably connected to the rotating seat 1001 through the moving channel. A cover plate that fits against the right side of the sealed box 2 is fixed to the right side of the sliding plate 1002.

[0048] The design of the moving channel facilitates the stable sliding of the sliding plate 1002, thereby improving the sliding stability of the cover plate.

[0049] It can be observed that a connecting block 1003 is fixed at the bottom of the sealed box 2, a swing rod 1004 is hinged to the top of the connecting block 1003, a connecting block 1005 fixed to the left side of the cover plate is fixed to the back of the swing rod 1004, and a pulling component is provided at the top of the connecting block 1003.

[0050] By adjusting the component settings, the efficiency of cover plate reset can be improved, thereby enhancing the overall structural performance, ease of use, and stable operation.

[0051] The pulling assembly includes a swing block 1006 hinged to the top of the connecting block 1003, a return spring 1007 fixed to the left side of the swing block 1006, and an extension plate 1008 fixed to the top of the connecting block 1003 fixed to the left side of the return spring 1007.

[0052] In this embodiment, the reset spring 1007 pulls the swing block 1006, which facilitates the pulling of the cover plate and provides tension to the cover plate when it is closed, thereby improving the ease of use of the structure.

[0053] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0054] The working principle of the above embodiments is as follows:

[0055] The drive motor 3 is started, which drives the drive gear 4 to rotate. Through meshing, the threaded rod 6 rotates. Through the sliding limit action of the sliding rod 9 and the sliding channel, and the threaded connection between the movable block 7 and the threaded rod 6, the movable block 7 moves up and down. This, in turn, drives the cleaning block 11 to move up and down through fixing, thereby cleaning the water seeping from the joints of the wall 1. At the same time, the sponge board 13 enhances the treatment of leaks, thus improving the waterproofness of the structure. If it is necessary to inspect and repair the structure inside the sealed box 2, the cover can be pulled forward. Through the rotation of the rotating seat 1001, the sliding plate 1002 and the cover rotate. Through the sliding connection between the sliding plate 1002 and the rotating seat 1001, the cover slides, thus flipping the cover to the left side of the front of the sealed box 2, opening the sealed box 2 for inspection. This improves the overall structural stability and makes it convenient to use.
