DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] The following is combined with the attached Figures 1-4A further detailed description of the present application is provided.

[0038] In the prior art, holes for passing through-wall pipes are usually provided on the wall, and there are gaps between the holes and the outer wall of the through-wall pipes, resulting in water seeping out from the gaps, causing the wall to be damp, moldy, and even structurally damaged.

[0039] An embodiment of the present application discloses a waterproof structure for through-wall pipes. Referring to Figure 1 and Figure 2 , the waterproof structure for through-wall pipes includes a connection assembly 1, a connection ring 2, a backing material 3, a caulking material 4, and a flange 5; the connection assembly 1 can be closely attached to the pipe and the wall 8, thereby filling the gap between the pipe and the wall 8, preventing water from penetrating through the gap between the pipe and the wall 8, and improving the problem of existing gaps between the through-wall pipe and the wall 8; and the connection ring 2 can abut against the wall 8 when the connection assembly 1 is displaced, thereby restricting the position of the connection assembly 1 and ensuring the fixed position of the waterproof structure for through-wall pipes.

[0040] As Figure 3 and Figure 4 shown, the connection assembly 1 includes a flexible bladder 11 and a filler 113. In the embodiment of the present application, the flexible bladder 11 is a double-layer structure, including an inner bladder 112 and an outer bladder 111. The inner bladder 112 is hollow and tubular, and the inner bladder 112 is filled with the filler 113. After the inner bladder 112 bulges due to the filler 113, it contacts the pipe while maintaining the basic structure of the connection assembly 1 and preventing the connection assembly 1 from becoming shriveled and flat; it should be noted that the filler 113 in the embodiment of the present application needs to be set according to the actual situation, and the present application does not specifically limit the material of the filler 113. For the sake of easy understanding, the filler 113 in the embodiment of the present application is pure water.

[0041] The outer bladder 111 is disposed on the outer surface of the inner bladder 112, and the outer bladder 111 contacts the wall 8. An overflow hole 115 is provided on the outer bladder 111, and a waterproof material 114 is filled between the inner bladder 112 and the outer bladder 111; specifically, the inner bladder 112 and the outer bladder 111 together fill the gap between the pipe and the wall 8, thereby preventing water from penetrating through the gap. The overflow hole 115 provided on the outer bladder 111 can overflow the waterproof material 114 to further fill the gap between the outer bladder 111 and the wall 8, further improving the problem of existing gaps between the existing through-wall pipe and the wall 8 and preventing water from penetrating through the gap; it should be noted that the waterproof material 114 needs to be set according to the actual construction situation, and the present application does not specifically limit the material of the waterproof material 114. For the sake of easy understanding, the waterproof material 114 in the embodiment of the present application is set as an adhesive obtained by mixing acrylate emulsion and water-based chloroprene rubber emulsion.

[0042] The outer surface of the outer bladder 111 is provided with an external thread 116, and a sealing strip 7 is detachably arranged on the outer surface of the outer bladder 111. The sealing strip 7 is symmetrically arranged with the overflow hole 115. The external thread 116 itself has a certain structural strength, which can support the outer bladder 111, keep the outer bladder 111 in a certain structure, and provide a certain basis for subsequent construction. The sealing strip 7 can prevent the waterproof material 114 from overflowing from the overflow hole 115 due to bumps and squeezes during the transportation of the connecting component 1, thereby preventing the component from deforming or being damaged due to vibrations during transportation. In the embodiment of the present application, the sealing strip 7 is a polyurethane sealing strip 7.

[0043] As Figure 4 shown, an internal thread is arranged on the inner wall of the connecting ring 2, and the internal thread is arranged to match the external thread 116. The connecting ring 2 is threadedly connected to the outer bladder 111 through the internal thread, so that the connecting ring 2 can limit the position of the outer bladder 111 by abutting against the wall, thereby limiting the position of the waterproof structure for the through-wall pipe and ensuring the stability of the position of the waterproof structure for the through-wall pipe.

[0044] As Figure 4 shown, in the embodiment of the present application, a backing material 3 is arranged between the flexible bladder 11 and the wall 8. The backing material 3 is specifically polyurethane. The backing material 3 can enhance the connection between the flexible bladder 11 and the wall 8, and ensure the stability and sealing performance of the waterproof structure for the through-wall pipe at the through-wall part by adhering to or fixing to the wall 8.

[0045] A caulking material 4 is also arranged at the connection of the backing material 3, the flexible bladder 11 and the wall 8. The caulking material 4 is specifically foamed polyurethane. The caulking material 4 can be quickly constructed by spraying or pouring, further filling the gap between the outer bladder 111 and the wall 8, further improving the problem of the existing gap between the through-wall pipe and the wall 8, and preventing water from penetrating through the gap.

[0046] The flange 5 is arranged at one end of the flexible bladder 11 away from the connecting ring 2, and the flange 5 is detachably connected to the wall 8. Specifically, the flange 5 is sleeved on the through-wall pipe and abuts against the pipe, and the flange 5 is detachably connected to the wall 8 through bolts 6 to limit the position of the through-wall pipe and simplify the installation of the waterproof structure for the through-wall pipe.

[0047] Specifically, the waterproof structure for the through-wall pipe in the embodiment of the present application can be installed in the following manner:

[0048] S1. Obtain the connecting component 1, tear off the sealing strip 7 on the surface of the connecting component 1, and insert one end of the connecting component 1 into the hole on the wall 8.

[0049] In step S1, the connecting component 1 is not completely inserted into the hole in the wall 8, and the connecting component 1 communicates with the hole in the wall 8.

[0050] S2. Obtain a wall-piercing pipe, insert the wall-piercing pipe into the connecting component 1 and push the wall-piercing pipe until the other end of the connecting component 1 passes through and protrudes from the other side of the wall 8.

[0051] In step S2, due to the pushing of the wall-piercing pipe and the friction with the wall 8, the connecting component 1 rotates inward, so that while the wall-piercing pipe passes through the connecting component 1, the connecting component 1 enters the hole in the wall 8; at the same time, the connecting component 1 is deformed by the extrusion of the wall-piercing pipe and the wall 8, so that the waterproof material 114 in the connecting component 1 overflows from the overflow hole 115 to fill the gaps between the wall-piercing pipe, the connecting component 1 and the wall 8 in pairs, improving the problem that there are gaps between the existing wall-piercing pipe and the wall 8.

[0052] S3. Obtain a flange 5 and bolts 6, sleeved the flange 5 on one end of the wall-piercing pipe, and insert the protruding part of the flange 5 into the gap between the wall-piercing pipe and the wall 8, and connect the flange 5 and the wall 8 through the bolts 6.

[0053] S4. Obtain a backing material 3 and a caulking material 4, squeeze the backing material 3 into the gap between the wall 8 and the connecting component 1 on the side away from the flange 5, and then spray the caulking material 4 into the gap between the surface of the wall 8, the connecting component 1 and the wall-piercing pipe.

[0054] S5. Obtain a connecting ring 2 and thread-connect the connecting ring 2 with the part of the connecting component 1 protruding from the wall 8.

[0055] All are preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
