Description

Technical Field

[0001] The present application relates to the field of building construction, and in particular to a water-leakage-proof structure for a reserved hole in a bathroom. Background Art

[0002] In house construction, especially in the bathrooms of residential buildings, risers are required to pass through the floor slabs, such as sewer pipes. When installing these risers, usually, a pipe installation hole for the riser installation is reserved when pouring concrete, and then the riser is installed in the pipe installation hole. After the riser installation is completed, the area around the riser is sealed to ensure the sealing between the riser and the pipe installation hole.

[0003] The sealing operation in the prior art is mainly performed by wrapping a waterproof tape around the pipe to seal it, and the waterproof tape is used to cover the gap between the riser and the pipe installation hole, thereby limiting water from seeping into the gap between the riser and the pipe installation hole.

[0004] Regarding the above-mentioned waterproofing method, since the gap between the riser and the pipe installation hole is located between the riser and the concrete layer, the upright riser will have a certain impact on the winding of the waterproof tape. If the winding is not good, water will easily penetrate through the gap between the waterproof tape and the concrete layer. The waterproofing effect depends on the operator's proficiency. Utility Model Content

[0005] In order to make the waterproof effect more stable, the present application provides a water leakage prevention structure with a reserved hole in the bathroom.

[0006] The present application provides a water-leakage-proof structure for a reserved hole in a bathroom, which adopts the following technical solutions:

[0007] A water leakage prevention structure for a reserved hole in a bathroom comprises a concrete layer, a vertical pipe, a water blocking ring and a pressing sleeve. The concrete layer is provided with an installation hole for installing the vertical pipe. The water blocking ring is sleeved on the vertical pipe. The pressing sleeve is threadedly installed on the vertical pipe. The water blocking ring is clamped between the pressing sleeve and the concrete layer.

[0008] By adopting the above technical solution, the gap between the riser and the concrete layer is sealed by the water-blocking ring, and water is restricted from seeping into the gap between the riser and the concrete layer by the water-blocking ring. At the same time, the water-blocking ring is squeezed by the pressing sleeve, so that the water-blocking ring maintains a fit state with the riser and the concrete layer, thereby improving the sealing effect. The pressing sleeve also restricts the riser from detaching from the mounting hole, thereby keeping the riser in a stable state, which is beneficial to the subsequent decoration process. The pressing sleeve is threadedly installed on the riser, making it easier to remove and install the pressing sleeve.

[0009] Optionally, the inner ring of the water-blocking ring abuts against the outer wall of the riser.

[0010] By adopting the above technical solution, the water blocking ring abuts against the outer wall of the riser, so that the gap between the water blocking ring and the riser is as small as possible, and the sealing between the water blocking ring and the riser is as good as possible.

[0011] Optionally, an inner wall of the pressing sleeve is provided with an inclined abutment surface, and the inclined abutment surface obliquely pushes the water-blocking ring toward the riser and the concrete layer.

[0012] By adopting the above technical solution, an inclined abutment surface is provided on the inner wall of the pressing sleeve, and an inclined force is applied to the water-blocking ring through the inclined abutment surface. The water-blocking ring is subjected to forces in the direction of the vertical pipe and the concrete layer. The limiting effect of the pressing sleeve on the water-blocking ring is exerted on the gap between the vertical pipe and the concrete layer as much as possible, so that the gap between the water-blocking ring and the vertical pipe is not easily increased due to pressure. Moisture flows into the gap between the pressing sleeve and the vertical pipe and contacts the water-blocking ring, and is not easily penetrated from the upper side of the water-blocking ring.

[0013] Optionally, the outer wall of the pressing sleeve is arranged at an angle, and the outer wall of the pressing sleeve extends from the upper side to the lower side in a direction away from the riser.

[0014] By adopting the above technical solution, the outer wall of the pressing sleeve is inclined, so that water is not easily accumulated on the pressing sleeve, the moisture on the upper side of the pressing sleeve is better guided away, and the possibility of moisture entering the gap between the pressing sleeve and the vertical pipe is reduced.

[0015] Optionally, the inclination of the outer wall of the pressing sleeve from the lower side to the middle is smaller than the inclination of the pressing sleeve from the middle to the upper side.

[0016] By adopting the above technical solution, the upper part of the pressing sleeve mainly plays the role of accelerating the flow of water, while the lower side of the pressing sleeve mainly guides the flow direction of water to be as horizontal as possible, and guides the water away from the pressing sleeve.

[0017] Optionally, a waterproof tape is wrapped between the vertical pipe and the concrete layer, and the waterproof tape covers the pressing sleeve.

[0018] By adopting the above technical solution, by further wrapping the waterproof tape between the riser and the concrete layer and covering the pressing sleeve with the waterproof tape, the flow of water into the water blocking ring position is reduced as much as possible.

[0019] Optionally, there are two water-blocking rings, which are respectively arranged above and below the concrete layer; and there are two pressing sleeves, which are respectively arranged above and below the concrete layer.

[0020] By adopting the above technical solution, two sets of water-blocking rings and pressing sleeves are provided, so that the upper and lower parts of the vertical pipe are restricted by the pressing sleeves. On the one hand, the vertical pipe is restricted in the installation hole of the concrete layer and remains stable. At the same time, the two pressing sleeves squeeze the two water-blocking rings respectively, and seal the upper and lower parts of the installation hole. The sealing effect formed by the two layers of sealing is better. At the same time, due to the restriction of the position of the vertical pipe by the pressing sleeve, the distance between the pressing sleeve and the concrete layer is kept smaller, and the deformation and sealing effect of the water-blocking ring after extrusion is more obvious.

[0021] Optionally, the cross section of the water blocking ring is triangular, and the water blocking ring is provided with a triangular surface matching the inclined abutting surface, and the remaining one surface of the water blocking ring abuts against the riser, and the other surface abuts against the concrete layer.

[0022] By adopting the above technical solution, the water blocking ring adopts a triangular shape, which better maintains the fitting effect, and the triangular surface of the water blocking ring and the inclined abutting surface are better extruded and matched.

[0023] To sum up, the gap between the riser and the concrete layer is sealed by the water-blocking ring, and the water-blocking ring is used to limit water from seeping into the gap between the riser and the concrete layer. At the same time, the water-blocking ring is squeezed by the pressing sleeve, so that the water-blocking ring maintains a fit state with the riser and the concrete layer, thereby improving the sealing effect. The pressing sleeve also plays a role in limiting the riser from detaching from the mounting hole, so that the riser remains in a stable state, which is beneficial to the subsequent decoration process. The pressing sleeve is threadedly installed on the riser, and the pressing sleeve is more convenient to remove and install. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is combined with Figure 1-4 This application is described in further detail.

[0030] The embodiment of the present application discloses a water leakage prevention structure for a reserved hole in a bathroom.

[0031] Reference Figure 1 and Figure 2 A water-leakage-proof structure for a reserved hole in the bathroom includes a concrete layer 1, a vertical pipe 2, a water-blocking ring 3 and a pressing sleeve 4. A vertically penetrating installation hole 11 is opened on the concrete layer 1, and the vertical pipe 2 passes through the installation hole 11. The two ends of the vertical pipe 2 are respectively located above and below the concrete layer 1. There are two water-blocking rings 3 and two pressing sleeves 4, and the two water-blocking rings 3 and the two pressing sleeves 4 are symmetrically arranged above and below the concrete layer 1.

[0032] Reference Figure 2 and Figure 3 Taking the area above the concrete layer 1 as an example, the water-blocking ring 3 is sleeved on the riser 2, and the pressing sleeve 4 is threadedly installed on the riser 2. The water-blocking ring 3 is clamped between the pressing sleeve 4 and the concrete layer 1. The pressing sleeve 4 includes a sleeve body 41, a sealing ring 42 and an extrusion block 43. The sleeve body 41 is threadedly installed on the riser 2. The sleeve body 41 is annular. The inner wall of the sleeve body 41 is threadedly engaged with the outer wall of the riser 2. The outer wall of the sleeve body 41 is inclined. The outer wall of the pressing sleeve 4 extends from the upper side to the lower side in a direction away from the riser 2. The inclination of the outer wall of the sleeve body 41 from the lower side to the middle is smaller than the inclination of the pressing sleeve 4 from the middle to the upper side, that is, the middle part of the outer wall of the sleeve body 41 is inclined and concave toward the riser 2 and the concrete layer 1, and the outer wall of the entire sleeve body 41 is a rounded arc surface.

[0033] An annular mounting groove 411 is provided on the inner side of the top wall of the sleeve 41, and the sealing ring 42 is embedded in the annular mounting groove 411 and sleeved on the outside of the standpipe 2. The extrusion block 43 is a stepped circular tube, and the extrusion block 43 is also threadedly installed on the outside of the standpipe 2. The lower part of the extrusion block 43 is screwed into the annular mounting groove 411 and squeezes the sealing ring 42, so that the sealing ring 42 can better seal the gap between the pressing sleeve 4 and the standpipe 2 after being deformed under pressure. The outer wall of the upper part of the extrusion block 43 cooperates with the outer wall of the sleeve 41 to form a mutually fitting connection, and an annular notch is provided on the inner opening of the sleeve 41 away from the extrusion block 43, so that an inclined abutment surface 412 is formed on the inner side of the sleeve 41 away from the extrusion block 43. The water blocking ring 3 is located below the inclined abutment surface 412, and the inclined abutment surface 412 obliquely pushes the water blocking ring 3 toward the standpipe 2 and the concrete layer 1.

[0034] Reference Figure 2 and Figure 4 The cross section of the water blocking ring 3 is triangular, and the water blocking ring 3 is provided with a triangular surface 31 that cooperates with the inclined abutment surface 412. The remaining two surfaces of the water blocking ring 3 are perpendicular to each other, one of which is the inner ring of the water blocking ring 3 and abuts against the riser 2, and the other surface abuts against the concrete layer 1. A ring-shaped fillet 32 protrudes from the side of the inner ring of the water blocking ring 3 away from the sleeve 41, and the fillet 32 directly abuts the gap between the mounting hole 11 and the riser 2.

[0035] Reference Figure 1 and Figure 2 At the same time, a waterproof tape 5 is wrapped between the vertical pipe 2 and the concrete layer 1, and the waterproof tape 5 covers the entire pressing sleeve 4.

[0036] The riser 2 is provided with matching external threads on the upper and lower parts of the concrete layer 1 , and the riser 2 can be installed with other pipe fittings after the water blocking ring 3 and the pressing sleeve 4 are installed.

[0037] The pressing sleeve 4 can also be made of two left and right parts connected and fixed by bolts. In this case, the pipe fittings below the riser 2 can be directly installed without affecting the installation of the pressing sleeve 4. The pressing sleeve 4 is first assembled outside the riser 2, and then the pressing sleeve 4 is rotated to complete the contact with the water-blocking ring 3. At this time, the pressing sleeve 4 is an integral whole and no longer needs to be separated into the three parts of the sleeve body 41, the sealing ring 42 and the extrusion block 43.

[0038] The implementation principle of the anti-leakage structure of the reserved hole in the bathroom in the embodiment of the present application is: moisture is blocked when it comes into contact with the waterproof tape 5. If the moisture passes through the waterproof tape 5, the moisture is blocked by the water-blocking ring 3, making it difficult for the moisture to directly enter the gap between the installation hole 11 and the vertical pipe 2.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
