Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology, and in particular to a drainage riser water-stop joint. Background Technology

[0002] In modern drainage systems, whether through-floor or same-floor, risers must penetrate the floor slab to reach the next unit. Depending on the riser type and opening design, the sealing requirements and construction techniques vary. However, due to factors such as different techniques, construction environment, and worker skill levels, the sealing quality of risers varies considerably. When water leaks, it flows down the pipe wall to the lower floor, flooding the living space below and causing economic losses and health hazards. Therefore, proper riser sealing is crucial.

[0003] While existing waterproof joints do provide waterproofing, leaks can still occur over time. Utility Model Content

[0004] This utility model provides a drainage riser water-stop joint with a multi-layer anti-seepage structure.

[0005] A drainage riser water-stop joint includes a pipe body, a first sealing ring, and a waterproof overflow ring. The pipe body is a hollow cylindrical structure suitable for a riser to pass through it. The first sealing ring is an annular structure, arranged circumferentially along the top of the pipe body, and a guide plate extends from the edge of the first sealing ring toward the bottom of the pipe body. The guide plate is filled with sealant between itself and the side wall of the pipe body. The waterproof overflow ring is positioned around the middle of the outer side of the pipe body, and an overflow groove is formed on the top of the waterproof overflow ring, corresponding to the guide plate.

[0006] In a specific embodiment of this utility model, the bottom of the guide plate is connected to the inner ring of the overflow tank, so that water enters the overflow tank through the guide plate.

[0007] In a specific embodiment of this utility model, the inner side of the first sealing ring is connected to the inner side of the pipe body, and the outer side of the first sealing ring extends upward along the riser.

[0008] In one specific embodiment of this utility model, the outer side of the first sealing ring extends outward, and the bottom of the first sealing ring is connected to the top of the concrete floor slab to provide support.

[0009] In one specific embodiment of this utility model, a second sealing ring is further included, which is disposed at the bottom of the tube body.

[0010] In one specific embodiment of this utility model, a base is also included. The base is a hollow annular plate structure. The base is disposed at the bottom of the tube body, and the bottom of the second sealing ring is connected to the top of the base.

[0011] In one specific embodiment of this utility model, a plurality of threaded holes are provided on the top of the annular plate structure, which are suitable for bolt connection to fix the tube body in the concrete floor slab.

[0012] In one specific embodiment of this utility model, a reinforcing rib is further included. The reinforcing rib is disposed between the waterproof overflow ring and the second sealing ring, and the number of the reinforcing ribs is multiple.

[0013] The beneficial effects of this utility model are as follows: By setting a first sealing ring at the top of the pipe body, and filling the gap between the first sealing ring and the riser with sealant, and setting a waterproof overflow ring at the upper middle position of the pipe body, when the first sealing ring leaks, the leaked water flows into the waterproof overflow ring, preventing it from flowing into the next floor. Setting a second sealing ring on the base is to better prevent water leakage. Through the above settings, this application sets a multi-layer waterproof structure, which avoids water leakage to the next floor residents after a long period of use, thus extending the service life.

[0023] In one specific embodiment of this utility model, the bottom of the guide plate is connected to the inner ring of the overflow tank, so that water enters the overflow tank through the guide plate.

[0024] Specifically, when an overflow occurs, the water is guided by the baffle plate into the overflow tank.

[0025] In a specific embodiment of this utility model, the inner side of the first sealing ring 210 is connected to the inner side of the pipe body 100, and the outer side of the first sealing ring 210 extends upward along the riser.

[0026] Specifically, such as Figure 1 As shown, in order to better achieve a sealing effect, the first sealing ring 210 is set at the top of the pipe body 100. The outer side of the first sealing ring 210 extends upward along the riser to seal the gap between the riser and the pipe body 100 and prevent water leakage.

[0027] In a specific embodiment of this utility model, the outer side of the first sealing ring 210 extends outward, and the bottom of the first sealing ring 210 is connected to the top of the concrete floor slab to provide support.

[0028] Specifically, such as Figure 1 As shown, in order to fix the tube body 100 in the designated position, the outer side of the first sealing ring 210 extends outward to support the tube body 100 and keep the tube body 100 at the same height.

[0029] In a specific embodiment of this utility model, a second sealing ring 220 is also provided, which is disposed at the bottom of the tube body 100; the provision of the second sealing ring 220 improves the sealing effect.

[0030] In a specific embodiment of this utility model, a base 400 is also included. The base 400 is a hollow annular plate structure. The base 400 is disposed at the bottom of the tube body 100. The bottom of the second sealing ring 220 is connected to the top of the base 400.

[0032] In a specific embodiment of this utility model, a reinforcing rib 500 is also included. The reinforcing rib 500 is disposed between the waterproof overflow ring 300 and the second sealing ring 220, and the number of reinforcing ribs 500 is multiple.

[0033] Specifically, such as Figure 1 As shown, multiple reinforcing ribs 500 are provided between the waterproof overflow ring 300 and the second sealing ring 220 to increase friction and better fix the pipe body 100 in the same position.

[0034] This application is available in various specifications: De50, De75, and De110, which can better meet the needs of conventional risers.

[0035] When using this utility model: first install the water-stop joint inside the concrete floor slab. The first sealing ring 210 is on the top of the concrete floor slab, which plays a supporting role. The base 400 is used to install the water-stop joint inside the concrete floor slab with bolts.

[0036] This application features a first sealing ring 210 at the top of the pipe body 100. A guide plate extends from the edge of the first sealing ring 210 towards the bottom of the pipe body 100. Sealant is filled between the guide plate and the side wall of the pipe body 100. A waterproof overflow ring 300 is located in the upper middle part of the pipe body 100. When the first sealing ring 210 leaks, the leaked water flows into the waterproof overflow ring 300, preventing it from flowing into the next floor. A second sealing ring 220 is installed on the base 400 to further prevent water leakage. A reinforcing rib 500 is installed between the waterproof overflow ring 200 and the second sealing ring 220 to increase friction and better secure the pipe body 100. This application, by setting up a multi-layered waterproof structure, prevents water from seeping into the next floor's residents after prolonged use, extending its service life. It also solves the problem that existing water-stop joints, while effective in preventing water seepage, still experience leakage problems after extended use.
