Wall longitudinal contraction joint edge finishing device

Abstract

This utility model discloses a wall longitudinal contraction joint edge-sealing device, belonging to the field of contraction joint technology. Its key technical features include two longitudinal wall bodies, with a water-stopping mechanism positioned between opposite sides of the two longitudinal wall bodies. A decorative cover body is positioned on the front side of each longitudinal wall body, and pulling mechanisms are positioned at the top and bottom of the rear side of the decorative cover body. The water-stopping mechanism includes four screws, two fixing frames, a water-stopping strip body, and two protrusions. The surface of the water-stopping strip body contacts the inner wall of the fixing frames. This solves the problem that in existing longitudinal wall contraction joint edge-sealing devices, the water-stopping strip, after installation, directly and tightly contacts the edge of the longitudinal wall. The rough and sharp edges of the wall can easily cause localized pressure damage to the rubber water-stopping strip, affecting the waterproofing effect. Furthermore, it is inconvenient to open the decorative cover, making it difficult to replace the aged water-stopping strip after long-term use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 The present invention provides the following technical solution:

[0028] The wall longitudinal contraction joint sealing device includes two longitudinal wall bodies 1. A water-stopping mechanism 2 is provided between the opposite sides of the two longitudinal wall bodies 1. A decorative cover body 4 is provided on the front side of the longitudinal wall body 1. Pulling mechanisms 6 are provided on the top and bottom of the rear side of the decorative cover body 4. The water-stopping mechanism 2 includes four screws 201, two fixing frames 202, a water-stopping strip body 203, and two protrusions 204. The surface of the water-stopping strip body 203 contacts the inner wall of the fixing frame 202. The front side of the protrusion 204 is fixedly connected to the rear side of the water-stopping strip body 203. The rear side of the screws 201 passes through the fixing frame 202 and the water-stopping strip body 203 and is threadedly connected to the interior of the longitudinal wall body 1. The rear side of the protrusion 204 is in close contact with the surface of the longitudinal wall body 1. The rear side of the fixing frame 202 is in close contact with the surface of the longitudinal wall body 1.

[0029] In this embodiment: the waterstop body 203 is inserted into the fixing frame 202 and fixed to the longitudinal wall body 1 by screws 201. Its surface protrusion 204 supports the wall, preventing the waterstop body 203 from directly contacting the rough edges of the longitudinal wall body 1, thus preventing localized compression damage and affecting waterproofing. The fixing frame 202 and the nitrile rubber protrusion 204 are in close contact with the longitudinal wall body 1 to form a sealing barrier. The decorative cover body 4 is quickly installed by inserting the insert 7 into the elastic aluminum alloy clip 8 of the fixing frame 202. The tension spring 10 pulls the clip 8 to prevent the clip 8 from disengaging from the insert 7 during the extension and retraction of the longitudinal wall body 1, causing the decorative cover to fall off. 9 provides support for the locking block 8 when the insert block 7 is inserted. During disassembly, the sealing block is removed by magnetically attracting the magnetic block 11 inside the silicone sealing block 3 with an external strong magnet. The decorative cover is quickly disassembled by pulling the hook 602 inside the external pull rope fixing cylinder 601, which facilitates the replacement of the aged waterstop. This solves the problem that when terminating the shrinkage joint of some existing longitudinal walls, the waterstop is directly in close contact with the edge of the longitudinal wall after installation. The rough and sharp edges of the wall can easily cause local pressure damage to the rubber waterstop in close contact with it, affecting the waterproof effect. In addition, it is inconvenient to open the decorative cover, which makes it inconvenient to replace the aged waterstop after long-term use.

[0030] Specifically, such as Figure 6 As shown, the pulling mechanism 6 includes a fixed cylinder 601, a hook 602, a retaining ring 603, and a through hole 604. The through hole 604 is opened inside the decorative cover body 4. The front side of the fixed cylinder 601 is fixedly connected to the rear side of the decorative cover body 4. The fixed cylinder 601 is connected to the through hole 604. The rear side of the hook 602 is fixedly connected to the rear side of the inner wall of the fixed cylinder 601. The retaining ring 603 is fixedly connected to the inner wall of the fixed cylinder 601.

[0031] Specifically, such as Figure 1 and Figure 6As shown, silicone sealing blocks 3 are provided at the top and bottom of the front side of the decorative cover body 4. The surface of the silicone sealing block 3 is in close contact with the inner wall of the through hole 604, and the rear side of the silicone sealing block 3 is in contact with the front side of the retaining ring 603.

[0032] Specifically, such as Figure 6 As shown, a magnetic block 11 is embedded inside the silicone sealing block 3.

[0033] In this embodiment: the fixed cylinder 601 of the pulling mechanism 6 is connected to the through hole 604. The hook 602 facilitates the removal of the decorative cover body 4 by attaching an external pull rope. The retaining ring 603 limits the silicone sealing block 3 to prevent it from going too deep into the fixed cylinder 601. The silicone sealing block 3 tightly seals the through hole 604 to prevent external moisture and debris from entering the fixed cylinder 601. With the help of the internal magnetic block 11, the sealing block can be quickly removed by an external strong magnet, providing a convenient operating channel for the removal of the decorative cover body 4 and ensuring the practicality and sealing of the pulling mechanism 6.

[0034] Specifically, such as Figure 5 As shown, the top and bottom of the front side of the fixed frame 202 are provided with locking blocks 8, and the top and bottom of the rear side of the locking blocks 8 are fixedly connected with tension springs 10, and the rear side of the tension springs 10 is fixedly connected to the front side of the fixed frame 202.

[0035] Specifically, such as Figure 2 and Figure 5 As shown, each of the four corners of the rear side of the decorative cover body 4 is fixedly connected with an insert 7 that works with the card block 8, and the insert 7 is inserted into the inside of the card block 8.

[0036] Specifically, such as Figure 5 As shown, support blocks 9 are fixedly connected to the top and bottom of the front side of the fixed frame 202, and the front side of the support block 9 contacts the rear side of the card block 8.

[0037] In this embodiment: the elastic aluminum alloy clip 8 and the insert 7 are inserted to realize the quick installation of the decorative cover. The tension spring 10 exerts a continuous pull on the clip 8 to ensure that the clip 8 does not detach from the insert 7 when the longitudinal wall body 1 is extended or retracted, thereby improving the connection stability of the decorative cover body 4. The support block 9 provides support for the clip 8 when the insert 7 is inserted. Together with the water-stopping mechanism 2, it realizes the finishing of the longitudinal wall contraction joint.

[0038] Specifically, such as Figure 2 As shown, sealing gaskets 5 are fixedly connected to both sides of the rear side of the decorative cover body 4, and the rear side of the sealing gaskets 5 is in close contact with the front side of the longitudinal wall body 1.

[0039] Specifically, such as Figure 2 and Figure 4 As shown, the sealing gasket 5, the waterstop body 203, and the protrusion 204 are all made of nitrile rubber.

[0040] Specifically, such as Figure 1 As shown, both the decorative cover body 4 and the fixing frame 202 are made of aluminum alloy, and the surfaces of both the decorative cover body 4 and the fixing frame 202 are coated with fluororesin.

[0041] In this embodiment: the nitrile rubber sealing gasket 5, the waterstop body 203, and the protrusion 204 enhance the sealing performance between the decorative cover and the longitudinal wall body 1 and the waterstop structure, thereby improving the waterproof performance and service life. The aluminum alloy decorative cover body 4 and the fixing frame 202 are coated with fluororesin coating, which significantly improves the corrosion resistance of the components, adapts to complex environments such as humidity and outdoor environments, and extends the overall service life of the edge finishing device.

[0042] Working principle: The waterstop body 203 is inserted into the fixed frame 202. Screws 201 pass through the fixed frame 202 and the waterstop body 203, fixing it between the two longitudinal wall bodies 1. The protrusions 204 on its surface support the longitudinal wall bodies 1, preventing the waterstop body 203 from directly contacting the rough edges of the longitudinal wall bodies 1, thus preventing local pressure damage. At the same time, the fixed frame 202 is in close contact with the wall to form the first line of sealing. The decorative cover body 4 is secured by the insertion of the four corner blocks 7 on its rear side and the locking blocks 8 on the front side of the fixed frame 202. Quick installation; the locking block 8 is made of aluminum alloy and has a certain degree of elasticity, facilitating the insertion and removal of the insert block 7; the tension spring 10 provides a pulling effect, allowing the decorative cover body 4 to pull the locking block 8 when the longitudinal wall body 1 expands and contracts, preventing the locking block 8 from breaking free from the insert block 7 and causing the decorative cover body 4 to fall off, thus sealing the shrinkage joint between the two longitudinal wall bodies 1; the support block 9 provides support for the locking block 8 when the insert block 7 is inserted; the hook 602 inside the fixed cylinder 601 of the pulling mechanism 6 is used to hang the external pull rope; during disassembly, the external strong magnet connects to the magnetic block 11 inside the silicone sealing block 3. After suction, remove the sealing block, and then hook it to the external pull rope 602. Pulling the hook 602 allows for quick disassembly of the decorative cover body 4, facilitating the replacement of the aged waterstop body 203. The sealing gasket 5, waterstop body 203, and protrusion 204 are all made of nitrile rubber, enhancing the seal between the decorative cover and the wall and extending the service life of the waterstop body 203, thereby improving the overall waterproofness of the edge finishing device. The surfaces of the aluminum alloy decorative cover body 4 and the fixing frame 202 are coated with fluoropolymer resin, effectively improving corrosion resistance and extending service life. Regarding the lifespan, this invention addresses the issue that when terminating the expansion joints of existing longitudinal walls, the installed waterstop is in direct and close contact with the edge of the longitudinal wall. The rough and sharp edges of the wall can easily cause localized pressure damage to the rubber waterstop, affecting the waterproofing effect. Furthermore, it is inconvenient to open the decorative cover, making it difficult to replace the aged waterstop after long-term use. It should be noted that the threaded connection between screw 201 and the internal thread of the longitudinal wall body 1 is a mature technology that has already been published, and expansion bolts or other methods can be used for connection, which will not be elaborated here.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
