Description

Technical Field

[0001] This utility model relates to the field of wall-penetrating pipe technology, and in particular to a multi-pipe wall-penetrating structure with high sealing performance. Background Technology

[0002] Through-wall pipes refer to pipes that are pre-embedded or installed in the walls of buildings to pass through structures such as walls and floors to achieve the connection and transmission of pipes and lines. Depending on different uses and needs, through-wall pipes can be divided into various types and have different structures and functions. If the pipe is not pre-embedded, a hole needs to be made in the wall before the pipe can pass through the hole and then a sealing structure is used to seal it.

[0003] A search revealed a Chinese patent (publication number CN220749294U) that discloses a multi-pipe dense wall penetration construction system. Although this patented technology fills the holes of the pipes to be penetrated with waterproof material after the installation of the pipes, using the lower inlet for filling and the upper vent for gas release to ensure a dense filling within the wall, the vent is located at the top, which can easily result in unfilled areas, leading to incomplete sealing. Furthermore, the gap between the positioning frame and the wall cannot be effectively sealed after installation. Therefore, those skilled in the art have proposed a multi-pipe wall penetration structure with high sealing performance to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highly sealing multi-tube through-wall structure. This structure uses multiple injection structures located at the lower part of the mounting hole and multiple vent holes located at the upper part to prevent air from escaping and causing holes that would affect the sealing performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-pipe wall-penetrating structure with high sealing performance, comprising a wall and an insulation board, wherein the insulation board is disposed at the rear end of the wall, and mounting holes are provided on the front end faces of both the wall and the insulation board. Four wall-penetrating pipes are arranged in a rectangular arrangement inside the two mounting holes. A first steel plate and a second steel plate are respectively provided on the front end of the outer wall and the rear end of the insulation board of the four wall-penetrating pipes. Multiple injection structures are arranged horizontally at the lower center of the rear end face of the first steel plate.

[0006] The injection structure includes a leak pipe. The front end of the leak pipe passes through the rear end face of the first steel plate and connects to the front end face of the injection structure. The rear end of the leak pipe passes through the front end face of the second steel plate and connects to the rear end face of the second steel plate. One-way valves are provided at both ends inside the leak pipe. First sealing plugs are threaded to both ends of the leak pipe.

[0007] A water baffle is fitted on the outside of the four through-wall pipes between the wall and the injection structure. Multiple vent holes are arranged horizontally at the upper center of the front end face of the first steel plate and the upper center of the rear end face of the second steel plate.

[0008] The above technical solution, with multiple injection structures located at the lower part of the mounting hole and multiple vent holes located at the upper part, can prevent the formation of holes caused by gas not being able to escape, thus affecting the sealing performance.

[0009] Furthermore, a sealing structure is provided at the edge of the rear end face of the first steel plate and at the edge of the front end face of the second steel plate. The sealing structure includes two rubber pads, which are respectively disposed on the rear end face of the first steel plate and the front end face of the second steel plate. Three grooves are provided on both the rear end face of the rubber pad at the front end and the front end face of the rubber pad at the rear end. The six grooves are respectively arranged in a concentric rectangle on the end face of the two grooves.

[0010] Through the above technical solution, the rubber pad will deform preferentially at the groove when under pressure, forming multiple sealing areas, further improving the sealing effect, thereby filling and sealing the gaps between the first steel plate and the second steel plate and between the wall and the insulation board.

[0011] Furthermore, a second sealing plug is threadedly connected to the interior of each of the multiple mounting holes at the front and the multiple vent holes at the rear.

[0012] The above technical solution improves sealing performance by filling the cavity and then sealing it with multiple second sealing plugs.

[0013] Furthermore, both the front end face of the first steel plate and the rear end face of the second steel plate are provided with reinforcing structures. The two reinforcing structures include eight L-shaped plates. The eight L-shaped plates are respectively located at the four opposite corners of the front end face of the first steel plate and the four opposite corners of the rear end face of the second steel plate. Both the front end face of the first steel plate and the rear end face of the second steel plate are provided with steel brackets. The two steel brackets are respectively located inside the eight L-shaped plates. Fixing screws are provided at the upper center of the front end face of the four L-shaped plates at the front and at the upper center of the rear end face of the four L-shaped plates at the rear. The eight fixing screws pass through the front end face of the four L-shaped plates at the front and the rear end face of the four L-shaped plates at the rear, and their ends are respectively threaded to the front end face of the steel bracket at the front and the rear end face of the steel bracket at the rear.

[0014] With the above technical solution, after filling, two steel brackets are placed inside the eight L-shaped plates, and eight fixing screws are used to fix the two steel brackets inside the eight L-shaped plates, thereby providing support for the edges of the first steel plate and the second steel plate, preventing the first steel plate and the second steel plate from being deformed due to excessive stress after long-term use, thus reducing the sealing performance.

[0015] Furthermore, the rear end face of the first steel plate is provided with four connectors arranged in a rectangular shape. The four connectors include four connecting rods. The front ends of the four connecting rods are all fixedly connected to the rear end face of the first steel plate, and the rear ends of the four connecting rods pass through the front end face of the second steel plate to the rear end of the second steel plate. Each end is threaded with two connecting nuts.

[0016] With the above technical solution, during installation, the four connecting rods at the rear end of the first steel plate are passed through the water baffle and the second steel plate, and then eight connecting nuts are used for threaded fixation.

[0017] This utility model has the following beneficial effects:

[0018] In this invention, the high-sealing multi-pipe through-wall structure removes multiple first sealing plugs by rotating them, and injects waterproof material into multiple leaking pipes through multiple one-way valves. Multiple vent holes are located at the lower ends of two rubber gaskets and in the gaps between the first steel plate and the second steel plate, and between the wall and the insulation board. This ensures that the filling material completely fills the installation holes, and any excess fills the gaps between the first steel plate and the second steel plate, and between the wall and the insulation board. After filling, multiple second sealing plugs are used for sealing, thereby improving the sealing performance.

[0019] In this utility model, during installation, the four connecting rods at the rear end of the first steel plate are passed through the baffle plate and the second steel plate, and then eight connecting nuts are used for threaded fixation. This makes the rubber pad at the rear end of the first steel plate and the rubber pad at the front end of the second steel plate fit tightly against the wall and the insulation board. When the rubber pad is under pressure, it will deform preferentially at the groove to form multiple sealing areas, further improving the sealing effect.

[0020] In this invention, after filling, two steel brackets are placed inside the eight L-shaped plates, and eight fixing screws are used to fix the two steel brackets inside the eight L-shaped plates, thereby providing support for the edges of the first steel plate and the second steel plate, preventing the first steel plate and the second steel plate from being deformed due to excessive stress after long-term use, thus reducing the sealing performance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1-4 This utility model provides an embodiment of a high-sealing multi-pipe wall-penetrating structure, including a wall 1 and an insulation board 2. The insulation board 2 is located at the rear end of the wall 1. Mounting holes 13 are provided on the front end faces of both the wall 1 and the insulation board 2. Four wall-penetrating pipes 7 are arranged in a rectangular arrangement inside the two mounting holes 13. A first steel plate 5 and a second steel plate 10 are respectively provided on the front end of the wall 1 and the rear end of the insulation board 2 outside the four wall-penetrating pipes 7. Multiple injection structures 3 are arranged horizontally at the lower center of the rear end face of the first steel plate 5, which facilitates the injection of waterproof material into the mounting holes 13.

[0029] The injection structure 3 includes a leak tube 301. The front end of the leak tube 301 passes through the rear end face of the first steel plate 5 and connects to the front end face of the injection structure 3. The rear end of the leak tube 301 passes through the front end face of the second steel plate 10 and connects to the rear end face of the second steel plate 10. One-way valves 302 are provided at both ends inside the leak tube 301. The front and rear ends of the leak tube 301 are threaded with first sealing plugs 303. By rotating the multiple first sealing plugs 303, the multiple first sealing plugs 303 can be removed, and waterproof material can be injected into the multiple leak tubes 301 through the multiple one-way valves 302.

[0030] A baffle plate 11 is fitted on the outside of the four through-wall pipes 7 between the wall 1 and the injection structure 3. Multiple vent holes 12 are arranged horizontally at the upper center of the front end face of the first steel plate 5 and the upper center of the rear end face of the second steel plate 10. Multiple injection structures 3 are set inside the lower part of the mounting hole 13. The multiple vent holes 12 are set at the upper part to prevent the formation of holes caused by gas not being able to escape, which would affect the sealing performance.

[0031] like Figure 3 , 4 As shown, a sealing structure 9 is provided at the edge of the rear end face of the first steel plate 5 and at the edge of the front end face of the second steel plate 10. The sealing structure 9 includes two rubber pads 901, which are respectively set on the rear end face of the first steel plate 5 and the front end face of the second steel plate 10. The rear end face of the rubber pad 901 at the front end and the front end face of the rubber pad 901 at the rear end are each provided with three grooves 902. The six grooves 902 are respectively arranged in a concentric rectangle on the end face of the two grooves 902. When the rubber pads 901 are compressed, they will deform preferentially at the grooves 902 to form multiple sealing areas, further improving the sealing effect, thereby filling and sealing the gaps between the first steel plate 5 and the second steel plate 10 and between the wall 1 and the insulation board 2.

[0032] like Figure 4 As shown, the interiors of the multiple mounting holes 13 at the front and the multiple vent holes 12 at the rear are all threaded with second sealing plugs 6. After filling, multiple second sealing plugs 6 are used to seal, thereby improving the sealing performance.

[0033] like Figure 1 , 2 As shown, both the front end face of the first steel plate 5 and the rear end face of the second steel plate 10 are provided with reinforcing structures 4. The two reinforcing structures 4 include eight L-shaped plates 401, which are respectively located at the four opposite corners of the front end face of the first steel plate 5 and the four opposite corners of the rear end face of the second steel plate 10. Both the front end of the first steel plate 5 and the rear end face of the second steel plate 10 are provided with steel brackets 402, which are respectively located inside the eight L-shaped plates 401. Fixing screws 403 are provided at the upper center of the front end face of the four L-shaped plates 401 at the front and at the upper center of the rear end face of the four L-shaped plates 401 at the rear. 03 passes through the front end face of the four L-shaped plates 401 at the front and the rear end face of the four L-shaped plates 401 at the rear, and the ends are respectively threaded to the front end face of the steel bracket 402 at the front and the rear end face of the steel bracket 402 at the rear. After filling, two steel brackets 402 are placed inside the eight L-shaped plates 401, and eight fixing screws 403 are used to fix the two steel brackets 402 inside the eight L-shaped plates 401, thereby providing support for the edges of the first steel plate 5 and the second steel plate 10, preventing the first steel plate 5 and the second steel plate 10 from being deformed due to excessive force after long-term use, thereby reducing the sealing performance.

[0034] like Figure 3 As shown, the rear end face of the first steel plate 5 is provided with four connectors 8 arranged in a rectangle. The four connectors 8 include four connecting rods 801. The front ends of the four connecting rods 801 are all fixedly connected to the rear end face of the first steel plate 5. The rear ends of the four connecting rods 801 all pass through the front end face of the second steel plate 10 and extend to the rear end of the second steel plate 10. Each end is threaded with two connecting nuts 802. During installation, the four connecting rods 801 at the rear end of the first steel plate 5 are passed through the baffle plate 11 and the second steel plate 10, and then the eight connecting nuts 802 are used for threaded fixation.

[0035] Working principle: Before use, the water baffle 11 is pre-embedded between the wall 1 and the insulation board 2. During installation, the four connecting rods 801 at the rear end of the first steel plate 5 are passed through the water baffle 11 and the second steel plate 10, and then eight connecting nuts 802 are used for threaded fixation. This makes the rubber pads 901 at the rear end of the first steel plate 5 and the rubber pads 901 at the front end of the second steel plate 10 fit tightly against the wall 1 and the insulation board 2. When under pressure, the rubber pads 901 will deform preferentially at the grooves 902 to form multiple sealing areas, further improving the sealing effect, thereby filling and sealing the gaps between the first steel plate 5 and the second steel plate 10 and between the wall 1 and the insulation board 2.

[0036] Then, by rotating the multiple first sealing plugs 303, the multiple first sealing plugs 303 are removed. Waterproof material is injected into the multiple leak pipes 301 through the multiple one-way valves 302. The multiple vent holes 12 are located at the lower ends of the two rubber gaskets 901 and in the gaps between the first steel plate 5 and the second steel plate 10 and between the wall 1 and the insulation board 2. This allows the filling to be completely filled into the installation hole 13, and the excess fills the gaps between the first steel plate 5 and the second steel plate 10 and between the wall 1 and the insulation board 2. After filling, the multiple second sealing plugs 6 are used to seal, thereby improving the sealing performance.

[0037] After filling, place two steel brackets 402 inside the eight L-shaped plates 401 and fix the two steel brackets 402 inside the eight L-shaped plates 401 with eight fixing screws 403, thereby providing support for the edges of the first steel plate 5 and the second steel plate 10, preventing the first steel plate 5 and the second steel plate 10 from being deformed due to excessive stress after long-term use, thus reducing the sealing performance.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
