[0002] In current building structure construction, a large number of water, heating and electricity wall-penetrating sleeves are designed on the outer walls of basements. In some areas, there are more local sleeves, forming sleeve groups. Since there are more sleeves at the location of the sleeve group and the spacing between adjacent sleeves is small, firstly, it is more difficult to install the formwork at the sleeve group, and it is easy to have problems such as leakage and slurry running. Secondly, the concrete in the sleeve group is not easy to vibrate and has poor density. The sleeve and concrete cannot have good and sufficient contact, so the sleeve cannot be firmly fixed in the concrete. After the concrete solidifies, there is a greater risk of water leakage.

[0003] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Utility Model Content

[0028] According to the specific embodiment of the present utility model, Figure 1-2 As shown, the utility model provides a group-pipe wall-penetrating waterproof structure, which includes:

[0029] The fixed flange 1 is provided with a plurality of through-holes, each of which is penetrated by a sleeve, and the sleeve is fully welded to the through-holes of the fixed flange 1; in this embodiment, the sleeve is fully welded to the through-holes of the fixed flange 1 to ensure that the gap between the sleeve and the fixed flange 1 is filled with the weld, and water leakage is unlikely to occur.

[0030] The movable flange 2 is provided with a plurality of through-holes, and the positions of the through-holes on the movable flange 2 are consistent with the positions of the through-holes on the fixed flange 1 , and a sleeve passes through each through-hole of the movable flange 2 .

[0031] The first waterproof layer 3 is provided between the fixed flange 1 and the movable flange 2, and covers the entire building structure 20 on one side close to the fixed flange 1. In this embodiment, the first waterproof layer 3 is provided with a perforation for the sleeve to pass through.

[0032] In this waterproof structure, a fixed flange 1 is provided, and multiple sleeves are fixed on the fixed flange 1. Then, the multiple sleeves and the fixed flange 1 are directly installed as a whole in the steel skeleton structure of the building. At this time, the fixed flange 1 itself can be used as a template; at the same time, a movable flange 2 is provided to press the first waterproof layer 3 onto the fixed flange 1, so that the first waterproof layer 3 is stably fixed on the side of the building structure 20 close to the fixed flange 1, and the first waterproof layer 3 can effectively play a good waterproof role between the fixed flange 1 and the movable flange 2; thereby ensuring that after the concrete of the building structure 20 solidifies, water leakage will not occur, and ensuring that the positions where the multiple sleeves pass through the wall have good waterproof performance.

[0033] A connecting rod 6 is provided between any adjacent sleeves 10, and a plurality of connecting rods 6 radiate outward from the outermost sleeve 10. The connecting rods 6 are all located in the same plane and are all located inside the building structure 20. In one embodiment of the present application, connecting rods 6 are provided between adjacent sleeves 10. Specifically, the ends of the connecting rods 6 are welded to the sleeves 10; this not only strengthens the connection strength between the sleeves 10, preventing the sleeves 10 from shifting relative to each other; but also, in this embodiment, the connecting rods 6 are tied to the steel bars in the building structure 20, and the connecting rods 6 can fully contact the concrete, thereby making the sleeves 10 more firmly fixed in the building structure 20, ensuring that the sleeves 10 embedded in the building structure 20 have sufficient stability.

[0034] A second waterproof layer 7 is provided on the side of the connecting rod 6 facing the fixed flange 1. In one embodiment of the present application, the second waterproof layer 7 is covered on the connecting rod 6 between the sleeves 10, that is, a waterproof layer is provided inside the building structure 20 where the entire sleeve group 10 is located, thereby achieving a better waterproof effect at the location of the sleeve group 10.

[0035] Swelling water-stopping adhesive 8 is provided around the periphery of sleeve 10 and disposed between fixed flange 1 and second waterproof layer 7. In one embodiment of the present application, swelling water-stopping adhesive 8 is used to provide waterproofing around the periphery of sleeve 10. In this embodiment, the first waterproof layer 3, the second waterproof layer 7, and the swelling water-stopping adhesive 8 therebetween cooperate with each other to provide a good waterproofing effect at the location of the sleeve 10 group embedded in the building structure 20.

[0036] A plurality of studs are provided on the side of the fixed flange 1 facing the movable flange 2, and a plurality of clearance holes are provided on the movable flange 2 corresponding to the positions of the studs of the fixed flange 1; the studs pass through the clearance holes so that the movable flange 2 can be installed on the fixed flange 1, and the nuts are tightened on the studs to fix the movable flange 2 relative to the fixed flange 1.

[0037] In one embodiment of the present application, after the movable flange 2 is installed on the stud of the fixed flange 1, the nut is tightened at the end of the bolt so that the movable flange 2 presses the first waterproof layer 3 onto the fixed flange 1, so that the movable flange 2, the first waterproof layer 3 and the fixed flange 1 are relatively fixed.

[0038] Double-sided butyl adhesive tape 4 is provided between the first waterproof layer 3 and the edges of the fixed flange 1 and the movable flange 2. In one embodiment of the present application, the double-sided butyl adhesive tape 4 is provided between the first waterproof layer 3 and the edges of the fixed flange 1 and the movable flange 2. This allows the double-sided butyl tape to not only temporarily secure the first waterproof layer 3 but also effectively seal the first waterproof layer 3 against the edges of the fixed flange 1 and the movable flange 2 after the movable flange 2 is pressed against the fixed flange 1.

[0039] The fixed flange 1 and the movable flange 2 are covered with a mortar waterproof layer 5. In one embodiment of the present application, the mortar waterproof layer 5 is a polymer cement mortar waterproof layer 5 with a thickness of 20 cm. The mortar waterproof layer 5 covers the outer periphery of the fixed flange 1 and the movable flange 2, thereby providing an additional layer of waterproof protection at the connection between the flange and the sleeve, making the waterproof structure have better waterproof performance.

[0040] The expansion water-stop adhesives 8 on adjacent sleeves 10 are arranged in a staggered manner. In this embodiment, when multiple expansion water-stop adhesives 8 are arranged in the same radial position, if one expansion water-stop adhesive 8 fails, a leak will appear in this radial plane. In this application, the expansion water-stop adhesives 8 are arranged in a staggered manner, so that the water-stopping ranges of the expansion water-stop adhesives 8 on adjacent sleeves 10 overlap to a certain extent in the axial direction, further improving the waterproof effect of the waterproof structure.

[0041] A connecting rod 9 is provided between the connecting rod 6 radiating outward from the outermost sleeve 10 and the fixed flange 1. In one embodiment of the present application, the connecting rod 9 provided between the connecting rod 6 and the fixed flange 1 not only plays a role in supporting the sleeve 10 to a certain extent, but also is buried in the concrete of the building structure 20, thereby increasing the overall structural strength of the waterproof structure and more firmly fixing the sleeve 10.

[0042] It will be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.
