DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 , 2 As shown, a waterproof structure for residential project construction includes a smoke and air duct 1, a water retaining sill 2 is arranged on the side of the smoke and air duct 1, the water retaining sill 2 is formed by secondary hanging hole pouring after the smoke and air duct 1 is installed, the smoke and air duct 1 runs through the floor slab 3, and an eight-shaped corner 4 is arranged at the contact position between the smoke and air duct 1 and the water retaining sill 2, and an eight-shaped corner 4 is also arranged at the contact position between the water retaining sill 2 and the floor slab 3. A waterproof membrane 5 is laid on the top of the floor slab 3 and the water retaining sill 2, and the waterproof membrane 5 extends to the side wall of the smoke and air duct 1. A fastening assembly 6 is arranged on the side wall of the smoke and air duct 1, and the fastening assembly 6 squeezes the waterproof membrane 5 and the smoke and air duct 1.

[0023] The smoke and air duct 1 is surrounded by floor slabs 3. Compared with the traditional smoke and air duct 1 that is close to the wall, the side walls of the smoke and air duct 1 in this embodiment are more than 20 cm away from the wall. Therefore, a waterproof structure can be laid around the smoke and air duct 1 to prevent water from seeping out from the contact area between the smoke and air duct 1 and the wall. Pipes arranged in the horizontal direction of the house can pass through the gap between the smoke and air duct 1 and the wall, so as to reasonably utilize the gap to reduce the waste of residential space.

[0024] The eight-shaped corner 4 is applied to the inner corner with height change. The eight-shaped corner 4 makes a smooth transition between the floor 3 and the water retaining sill 2, and between the water retaining sill 2 and the smoke and air duct 1, so that the waterproof membrane 5 can be laid smoothly, avoiding damage caused by excessive bending of the waterproof membrane 5, and ensuring the waterproof effect of the waterproof membrane 5.

[0025] An anti-ridge 31 is built on the floor 3, and the anti-ridge 31 surrounds the water retaining ridge 2. There is a spacing between the water retaining ridge 2 and the anti-ridge 31, and waterproof membrane 5 is laid at the spacing. The waterproof membrane 5 extends and is laid on the side wall of the anti-ridge 31. The contact part between the floor 3 and the anti-ridge 31 is also coated with an eight-shaped corner 4. The end of the waterproof membrane 5 is arranged on the higher anti-ridge 31 to prevent water from penetrating into the floor 3 from the end of the waterproof membrane 5. The waterproof membrane 5 is in a basin shape and can block more water.

[0026] The fastening assembly 6 further clamps the waterproof roll 5 attached to the side wall of the smoke and air duct 1 to prevent water from penetrating from the joint of the waterproof roll 5. Figure 3As shown, the fastening assembly 6 includes a first fastening rod 61, a second fastening rod 62, a tension rod 63 and a push block 64. The first fastening rod 61 and the second fastening rod 62 are alternately arranged on the four sides of the smoke and air duct 1, the two first fastening rods 61 are arranged opposite to each other, and the two second fastening rods 62 are arranged opposite to each other. The first fastening rod 61 and the second fastening rod 62 are in contact with the waterproof membrane 5. The tension rod 63 passes through the two opposite first fastening rods 61, and the tension rod 63 tightens the first fastening rod 61. The push block 64 is slidably connected to the tension rod 63, and the push block 64 pushes the second fastening rod 62 to press the waterproof membrane 5.

[0027] Extension rods 611 are provided at both ends of the first fastening rod 61, and notches 621 are opened at both ends of the second fastening rod 62. The extension rod 611 passes through the notch 621. The length of the notch 621 is greater than the distance from the end of the second fastening rod 62 to the smoke and air duct 1. The extension rod 611 can slide along the direction of the notch 621. After the extension rod 611 is inserted into the notch 621, it moves along the notch 621 to make the first fastening rod 61 close to the waterproof membrane 5.

[0028] The extension rod 611 is provided with a through hole, and the tension rod 63 passes through the through hole. Both ends of the tension rod 63 are provided with threads, and both ends of the tension rod 63 are screwed with a first fastening nut 631. After the first fastening rod 61 is pressed against the waterproof membrane 5, the first fastening nut 631 is tightened so that the first fastening nut 631 is pressed against the extension rod 611 to fix the position of the first fastening rod 61.

[0029] Each tie rod 63 is slidably connected to a plurality of push blocks 64 , which are also provided with through holes. The tie rods 63 pass through the through holes, and the push blocks 64 can slide on the tie rods 63 . The number and position of the push blocks 64 can be determined according to the length of the tie rods 63 .

[0030] A push rod 641 passes through the bottom of the pushing block 64. The push rod 641 is a cylindrical rod and can slide along the pushing block 64. A push piece 642 is provided at the front end of the push rod 641. The push piece 642 is an L-shaped piece. The push piece 642 contacts the bottom of the second fastening rod 62. The push piece 642 pushes the side wall of the second fastening rod 62, further allowing the second fastening rod 62 to press the waterproof membrane 5.

[0031] The side wall of the push rod 641 is provided with a thread, and a second fastening nut 643 is screwed between the rear end of the push piece 642 and the propulsion block 64. When the push piece 642 fixes the second fastening rod 62, the second fastening nut 643 is screwed toward the propulsion block 64 to prevent the push rod 641 from moving backward, thereby completing the fixation of the push rod 641 and the push piece 642.

[0032] The waterproof membrane 5 is laid around the smoke and air duct 1, and the first fastening rod 61 and the second fastening rod 62 use external machinery to fix the waterproof membrane 5 at the smoke and air duct 1, further preventing water from seeping out from the waterproof membrane 5, so that the water flowing into the root of the smoke and air duct 1 cannot continue to flow to the downstairs of the residential building, thereby strengthening the waterproof ability of the weak points of the hanging hole and enhancing the overall waterproof effect of the house.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
