Description

Technical Field

[0001] This application relates to the field of pipe waterproofing, specifically a waterproofing structure for pipe penetration in floor slabs. Background Technology

[0002] Buildings typically contain multiple pipes, such as fire hydrants, water supply pipes, and gas supply pipes. During installation, these pipes usually need to pass through floor slabs to reach the upper and lower floors. After passing through the floor slabs, waterproofing is required to prevent water from seeping from the upper floors down the pipes to the lower floors.

[0003] Utility model patent CN220957185U discloses a device for improving the waterproofing performance of pipes penetrating floor slabs. The device includes a hollow pipe embedded in a concrete floor slab, with a water-stop ring coaxially welded to the outer wall of the hollow pipe. The water-stop ring is also embedded in the concrete floor slab. The device further includes: oil-impregnated hemp fibers wrapped around the outer wall of the hollow pipe and abutting against the top wall of the concrete floor slab; a sealing rubber ring, tapered and protruding near the hollow pipe, fitted onto the hollow pipe and abutting against the top wall of the concrete floor slab, with its inner wall flared near the bottom and pressed against the oil-impregnated hemp fibers; a pressure ring abutting against the sealing rubber ring; and multiple expansion bolts fixedly inserted into the concrete floor slab, extending beyond the sealing rubber ring and pressure ring, with threaded nuts connected to their threaded sections for abutting against the pressure ring. This utility model effectively improves the waterproofing performance between the pipe and the floor slab.

[0004] The device contains hollow pipes embedded in the floor slab. The outer wall of the hollow pipes is also fitted with oil-impregnated hemp fibers and sealing rubber rings at the outer end of the floor slab. However, since the hollow pipes are directly embedded in the floor slab, they are prone to vibration when transporting gas or liquid. After prolonged vibration, gaps may form between the embedded section of the hollow pipes and the floor slab, affecting the waterproof performance of the connection between the floor slab and the hollow pipes. Utility Model Content

[0005] In view of the problem of poor waterproof performance in the existing technology, this utility model provides a waterproof structure for pipe penetration in floor slabs.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] This utility model provides a waterproof structure for pipe penetration in floor slabs, including a sleeve embedded in the floor slab. A water-stop ring is fixedly installed on the outer wall of the sleeve. A through hole is provided inside the sleeve, through which a pipe is inserted. A sealing mechanism is provided on both sides of the sleeve and the floor slab. The sealing mechanism includes a fixing ring, an end cap, and an elastic sealing gasket. The fixing ring is fixedly installed on the inner wall of the through hole. The end cap is installed on the outer side of the sleeve. One end of the end cap is inserted into the through hole. An elastic sealing gasket that abuts against the fixing ring is provided at the end of the end cap in the through hole.

[0008] It also includes a fixing mechanism, which is disposed on the end cap.

[0009] Preferably, the fixing mechanism includes an adjusting rod. The top of the end cap is provided with multiple sets of countersunk holes spaced circumferentially. The sleeve is provided with threaded holes aligned with the countersunk holes. The adjusting rod passes through the countersunk holes and is inserted into the threaded holes. The operator inserts the adjusting rod into the multiple sets of countersunk holes on the end cap, and then threaded the adjusting rod into the threaded holes to achieve convenient fixing of the end cap and the sleeve, making it easy to install and remove the end cap.

[0010] Preferably, it also includes a sealing ring, which is located on the outside of the sleeve and fitted onto the pipe. The sealing ring abuts against the inner wall of the end cap. By fitting the sealing ring between the end cap and the pipe, the sealing performance between the end cap and the pipe is further improved, ensuring waterproofness.

[0011] Preferably, a rubber pad is provided on the side of the fixing ring near the outer wall of the pipe. By providing a rubber pad on the inner wall of the fixing ring, the pipe is prevented from directly colliding with the fixing ring when it vibrates, thus ensuring the safety of the pipe.

[0012] Preferably, the outer wall of the sleeve is coated with a waterproof coating, which ensures the waterproofness of the connection between the sleeve and the floor slab when the sleeve is pre-embedded.

[0013] Preferably, the outer edge of the end cap is inclined. The inclined surface on the outer edge of the end cap allows rainwater to be guided through the surface, preventing rainwater from accumulating at the connection between the end cap and the pipe.

[0014] Preferably, both sides of the floor slab are provided with waterproof mortar layers. The waterproof mortar layers on both sides of the floor slab enable the floor slab itself to have good waterproof performance and prevent rainwater penetration.

[0015] The advantages of adopting the above technical solution are:

[0016] This utility model includes a sleeve embedded in the floor slab. A water-stop ring is fixedly installed on the outer wall of the sleeve. A through hole is provided inside the sleeve, through which a pipe passes. A sealing mechanism is provided on both sides of the sleeve and the floor slab. The sealing mechanism includes a fixing ring, an end cap, and an elastic sealing gasket. The fixing ring is fixedly installed on the inner wall of the through hole, and the end cap is located on the outer side of the sleeve. One end of the end cap is inserted into the through hole, and an elastic sealing gasket is provided at the end of the end cap in the through hole, which abuts against the fixing ring. In this device, the elastic sealing gasket at one end of the end cap allows the elastic sealing gasket to simultaneously abut against the inner wall of the through hole and the outer wall of the pipe when the end cap is inserted into the gap between the sleeve and the pipe. Furthermore, when the pipe vibrates, the elastic sealing gasket can deform synchronously, preventing rainwater from seeping through the gap, ensuring stable sealing, and improving waterproof performance.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figure 1-3As shown in the figure, this utility model embodiment discloses a waterproof structure for a floor slab with through-pipes, including a sleeve 2 and a fixing mechanism. The sleeve 2 is embedded in the floor slab 1. A water-stop ring 201 is fixedly installed on the outer wall of the sleeve 2. A through hole 200 is provided in the sleeve 2, and a pipe 3 is inserted through the through hole 200. A set of sealing mechanisms is provided on both sides of the sleeve 2 and the floor slab 1 respectively. The sealing mechanism includes a fixing ring 202, an end cap 4 and an elastic sealing gasket 401. The fixing ring 202 is fixedly installed on the inner wall of the through hole 200. The end cap 4 is installed on the outer side of the sleeve 2. One end of the end cap 4 is inserted into the through hole 200. An elastic sealing gasket 401 that abuts against the fixing ring 202 is provided on one end of the end cap 4 in the through hole 200. The fixing mechanism is provided on the end cap 4.

[0024] In at least one embodiment, the fixing mechanism includes an adjusting rod. The top of the end cap 4 is provided with multiple sets of countersunk holes 402 spaced circumferentially. The sleeve 2 is provided with threaded holes aligned with the countersunk holes 402. The adjusting rod passes through the countersunk holes 402 and is inserted into the threaded holes. The operator inserts the adjusting rod into the multiple sets of countersunk holes 402 on the end cap 4, and then threaded the adjusting rod into the threaded holes, thereby achieving convenient fixing of the end cap 4 and the sleeve 2, which facilitates the installation and removal of the end cap 4.

[0025] In at least one embodiment, a sealing ring 5 is also included. The sealing ring 5 is located outside the sleeve 2 and is fitted onto the pipe 3. The sealing ring 5 abuts against the inner wall of the end cap 4. By fitting the sealing ring 5 between the end cap 4 and the pipe 3, the sealing performance between the end cap 4 and the pipe 3 is further improved, ensuring waterproofness.

[0026] In at least one embodiment, a rubber pad is provided on the side of the fixing ring 202 near the outer wall of the pipe 3. By providing a rubber pad on the inner wall of the fixing ring 202, the pipe 3 is prevented from directly colliding with the fixing ring 202 when it vibrates, thus ensuring the safety of the pipe 3.

[0027] In at least one embodiment, the outer wall of the sleeve 2 is coated with a waterproof coating, which ensures the waterproofness of the connection between the sleeve 2 and the floor slab 1 when the sleeve 2 is pre-embedded.

[0028] In at least one embodiment, the outer edge of the end cap 4 is set to be inclined. The inclined surface on the outer edge of the end cap 4 allows rainwater to be guided through the inclined surface when there is rainwater on the end cap 4, thus preventing rainwater from accumulating at the connection between the end cap 4 and the pipe 3.

[0029] In at least one embodiment, waterproof mortar layers 101 are provided on both sides of the floor slab 1. The waterproof mortar layers 101 provided on both sides of the floor slab 1 enable the floor slab 1 itself to have good waterproof performance and prevent rainwater penetration.

[0030] During the pipe installation in floor slab 1, workers pre-embed sleeve 2 at the pipe installation location during floor slab 1 pouring. The water-stop ring 201 on the outer wall of sleeve 2 prevents water from seeping through the connection of sleeve 1 at the outer end of floor slab 1. During pipe installation, pipe 3 is inserted into the through hole 200 of sleeve 2. After pipe 3 is installed, workers place two sets of end caps 4 on both sides of floor slab 1 onto pipe 3, ensuring the end caps 4 abut against the outer end of sleeve 2. At this point, one end of end cap 4 is located within the through hole 200 and inserted into the gap between pipe 3 and sleeve 2. During insertion, the elastic sealing gasket 401 at one end of end cap 4 abuts against both the outer wall of pipe 3 and the inner wall of through hole 200. Under continuous pressure from the staff, the elastic sealing gasket 401 moves to the fixing ring 202 and abuts against the fixing ring 202 for limiting. The elastic sealing gaskets 401 on the two sets of end caps 4 seal the gap between the collar and the pipe 3, preventing water from entering the other side of the floor slab 1 through the gap between the pipe 3 and the sleeve 2. When the pipe 3 vibrates, the elastic sealing gasket 401 can deform with the vibration of the pipe 3, thus ensuring that the elastic sealing gasket 401 can always seal the gap between the pipe 3 and the sleeve 2, improving the waterproof performance. The fixing mechanism can fix the end cap 4 and the sleeve 2, ensuring the stability of the end cap 4 and the elastic sealing gasket 401, and ensuring stable waterproof performance.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
