Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular to a waterproof structure for building expansion joints. Background Technology

[0002] Construction engineering refers to the physical engineering project formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities.

[0003] Existing waterproofing methods for building expansion joints mostly involve filling the expansion joints with waterproof expansion materials to improve the waterproofing effect between walls. However, in actual use, the long-term and repeated expansion and contraction of walls can cause the waterproofing material between the expansion joints to decompose, thus directly affecting the waterproofing effect of the expansion joints. Therefore, there is an urgent need for a waterproofing structure for building expansion joints to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof structure for expansion joints in building engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for expansion joints in building engineering, including a wall and a rectangular frame for waterproofing the sidewalls of the wall, an installation plate is provided between the two walls, two push springs are symmetrically fixedly installed on both sides of the installation plate, the ends of the two push springs are fixedly connected to the rectangular frame, and the two rectangular frames are fitted onto the sidewalls of the wall.

[0006] A U-shaped frame is fixedly installed on the side wall of the mounting plate. The side wall of the U-shaped frame has multiple circular grooves, and threaded holes are opened in the circular grooves. The side wall of the wall has corresponding limit screw grooves, and the internal threads of the threaded holes and limit screw grooves are connected to limit screws for installation of expansion joint waterproof structures.

[0007] The opening of the U-shaped frame is provided with a vertical plate and the side wall of the mounting plate are provided with limit holes, and the internal thread of the limit holes is connected to a threaded rod.

[0012] Preferably, sealing strips are symmetrically fixedly installed on the inner wall of the U-shaped frame and on the side of the vertical plate near the wall, and the side wall of the sealing strip is sealed and fitted to the side wall of the wall.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] The waterproof structure for expansion joints in this building project benefits from the installation of mounting plates, push springs, and rectangular frames. Multiple push springs can push the rectangular frames fixed at their ends to seal and engage with the side walls of the wall, thereby waterproofing the expansion joints between the walls.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 4 The main structure of the waterproof structure for expansion joints in building engineering is a wall 1 and a rectangular frame 5 for waterproofing the side wall of the wall 1. An installation plate 3 is provided between the two walls 1. Two push springs 4 are symmetrically fixed on both sides of the installation plate 3. The ends of the two push springs 4 are fixedly connected to the rectangular frame 5, and the two rectangular frames 5 are fitted onto the side wall of the wall 1. Thanks to the installation plate 3, push springs 4 and rectangular frames 5, the rectangular frames 5 can be pushed by multiple push springs 4 to seal and engage with the side wall of the expansion joint in the wall 1, thereby waterproofing the expansion joint between the walls 1. At the same time, thanks to the compression of the push springs 4, the waterproof effect of the expansion joint can be guaranteed at all times.

[0028] A U-shaped frame 2 is fixedly installed on the side wall of the mounting plate 3. The side wall of the U-shaped frame 2 has multiple circular grooves 6. Threaded holes 7 are opened in the circular grooves 6. The side wall of the wall 1 is provided with a limit screw groove corresponding to the threaded hole 7. The threaded hole 7 and the limit screw groove are connected by internal threads to a limit screw rod 8 for the installation of the expansion joint waterproof structure.

[0029] The opening of the U-shaped frame 2 is provided with a vertical plate 9 and the side wall of the mounting plate 3 is provided with a limiting hole 10. The internal thread of the limiting hole 10 is connected to a threaded rod 11. Thanks to the structure of the U-shaped frame 2, the limiting screw 8, the threaded rod 11 and the vertical plate 9, the mounting plate 3 and the two rectangular frames 5 can be effectively installed into the expansion joint of the wall 1. At the same time, the stability of the mounting plate 3 and the rectangular frames 5 is further improved, and the waterproof effect of the expansion joint is further improved.

[0030] The nuts of the threaded rod 11 and the limiting screw 8 are rotated and extended into the limiting hole 10 and the circular groove 6 respectively and sealed together. This prevents external moisture from entering the expansion joint of the wall 1 through the threaded hole 7 and the limiting hole 10, thereby further improving the waterproof effect of the expansion joint of the wall 1.

[0031] Multiple limiting rods 12 are fixedly installed on the side of the rectangular frame 5 near the mounting plate 3. The side wall of the mounting plate 3 is provided with limiting grooves 13 corresponding to the limiting rods 12. The multiple limiting rods 12 fixedly installed on the side wall of the rectangular frame 5 slide and extend into the limiting grooves 13 provided on the side wall of the mounting plate 3. Thanks to the setting of the limiting rods 12, the sliding direction of the rectangular frame 5 can be effectively limited, and the stability of the rectangular frame 5 can be further improved, thereby further improving the sealing effect of the expansion joint between the rectangular frame 5 and the wall 1.

[0032] A sealing gasket 14 is fixedly bonded to the inner wall of the rectangular frame 5. The inner wall of the sealing gasket 14 is sealed and adhered to the side wall of the wall 1. The sealing gasket 14 can seal and adhere to the inner wall of the rectangular frame 5 and the wall 1, thereby further improving the sealing effect of the rectangular frame 5.

[0033] Sealing strips 15 are symmetrically fixed to the inner wall of the U-shaped frame 2 and the side of the vertical plate 9 near the wall 1. The side wall of the sealing strip 15 is sealed and fitted to the side wall of the wall 1. Thanks to the setting of the sealing strip 15, the sealing effect between the inner wall of the U-shaped frame 2 and the side wall of the vertical plate 9 and the wall 1 can be improved, and the waterproof effect of the expansion joint of the wall 1 can be further improved.

[0034] Working principle

[0035] When using this waterproof structure for expansion joints in building construction, the U-shaped frame 2 is first snapped onto the side wall of the expansion joint of wall 1. At the same time, the mounting plate 3 fixedly installed inside the U-shaped frame 2 and the two rectangular frames 5 installed on the side wall of the mounting plate 3 are inserted into the interior of the expansion joint. Then, multiple push springs 4 fixedly installed on the side wall of the mounting plate 3 push the rectangular frames 5 fixedly installed at their ends to snap onto the side wall of the expansion joint of wall 1, thereby waterproofing the expansion joint. Finally, the U-shaped frame 2 and the vertical plate 9 are sealed and installed on the side wall of wall 1 by the limiting screw 8 and the threaded rod 11.
