Description

Technical Field

[0001] The utility model relates to the technical field of plugging devices, in particular to a plugging device for a wall-piercing sleeve. Background Technique

[0002] A wall-piercing sleeve is a pipeline device used to penetrate partition walls, partition boards or ceilings in buildings or structures. It is usually used for the wiring of power lines, telecommunication lines, pipelines, etc., so as to be installed and maintained without damaging the building structure. Some wall-piercing sleeves are pre-fixed on both sides of the building formwork by plugging devices and formed together with concrete pouring.

[0003] The utility model patent with the publication number of CN220366049U discloses a plugging device for a wall-piercing sleeve, which includes a wooden formwork, a sleeve positioning component and a wall-piercing sleeve. A hole is provided at the center of the wooden formwork, and the hole is designed as a regular hexagon. The sleeve positioning component is arranged on the outer side of the wooden formwork. The sleeve positioning component includes a fixing block and a fastening ring. The fixing block includes a fastening plate, a guide post and a spring. A telescopic joint is provided at the front end of the fixing block. In the utility model, under the reaction force of the spring in the sleeve positioning component, the fastening plate is tightly attached to the outer surface of the wall-piercing sleeve, reducing the gap with the wall-piercing sleeve and effectively avoiding the leakage of concrete slurry during the concrete pouring process at the sleeve position.

[0004] However, it still has certain problems: 1) The wall-piercing sleeve is mostly made of plastic material and is of a hollow structure. It will be subjected to a certain impact force during the concrete pouring process, which is likely to cause bending or fracture at the connection part between the sleeve and the formwork; 2) There is no plugging structure at the end of the sleeve, which is likely to cause impurities to enter the inside of the sleeve, posing a blockage hazard; 3) The sleeve is prone to tilt and shift; Therefore, in view of the above current situation, there is an urgent need to develop a plugging device for a wall-piercing sleeve to overcome the deficiencies in current practical applications and meet the current needs. Content of the Utility Model

[0005] The purpose of the utility model is to provide a plugging device for a wall-piercing sleeve to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A plugging device for a wall-piercing sleeve, which includes a plugging mechanism, a sleeve and a building formwork. The sleeve is penetrated between two building formworks, and the plugging mechanism is nested and installed at the end of the sleeve;

[0007] The plugging mechanism includes an inner shaft, a positioning ring, an inner support block, a locking nut, a sleeve and a plug. The inner shaft is horizontally penetrated inside the sleeve. The positioning ring, the inner support block and the locking nut are sequentially sleeved at both ends of the inner shaft. The sleeve is nested at the end of the sleeve and is fixedly connected to the building formwork. The plug is horizontally arranged at the end of the sleeve and is detachably connected to the sleeve.

[0010] Preferably, the outer diameter of the inner support block is equal to the inner diameter of the sleeve. Specifically, it is located at the staggered part of the sleeve and the building formwork.

[0011] Preferably, an integrally formed base is provided at the bottom end of the sleeve, and an integrally formed flange a is provided at the top end of the sleeve. An isolation cylinder is welded at the middle position of the base. The inner diameter of the isolation cylinder is consistent with the inner diameter of the sleeve, and the length of the isolation cylinder is consistent with the thickness of the building formwork. Specifically, after installation, the isolation cylinder is located between the sleeve and the building formwork, which can prevent mortar from adhering to the outer wall of the sleeve at the external part of the wall during concrete pouring, reduce the difficulty of subsequent formwork removal and cleaning, and at the same time can protect the sleeve and prevent the sleeve from being bent and broken at the interface part with the concrete wall.

[0012] Preferably, a flange b is welded at one end of the plug. The flange b is adapted to the flange a. Specifically, the plug and the sleeve are connected through the provided flange to improve their connection strength.

[0015] Beneficial effects:

[0016] 1. Inside it, the inner shaft is paired with a columnar inner support block to support the vulnerable part of the sleeve, which can effectively improve the anti-bending strength of the sleeve and prevent it from being damaged during the wall pouring process;

[0017] 2. It uses a plug and a sleeve to plug both ends of the sleeve to prevent mortar and dust from entering the sleeve or even blocking it during the wall pouring process;

[0031] The plugging mechanism 10 includes an inner shaft 101, a positioning ring 102, an inner support block 103, a locking nut 104, a sleeve 105 and a plug 106. The inner shaft 101 is horizontally arranged inside the bushing 20. The positioning ring 102, the inner support block 103 and the locking nut 104 are sequentially sleeved at both ends of the inner shaft 101. The sleeve 105 is nested at the end of the bushing 20 and is fixedly connected to the building formwork 30. The plug 106 is horizontally arranged at the end of the sleeve 105 and is detachably connected to the sleeve 105.

[0034] Preferably, the outer diameter of the inner support block 103 is equal to the inner diameter of the bushing 20. Specifically, it is located at the intersection of the bushing 20 and the building formwork 30. The inner support block 103 is a hollow column, which can form a support effect on the inner wall of the bushing 20 to prevent the bushing 20 at this part from being bent, deformed or even broken under force.

[0035] Preferably, the bottom end of the sleeve 105 is provided with an integrally formed base 1052, and the top end of the sleeve 105 is provided with an integrally formed flange a 1053.

[0038] Working principle: First, insert the isolation cylinder 1051 of the sleeve 105 into the through hole opened in the building formwork 30. Then, use screws and the base 1052 to fix the sleeve 105 on the outer wall of the building formwork 30. Next, insert the inner shaft 101 and the sleeve 20 through the inside of the sleeve 105. Then, use bolts to connect the flange b1061 of the plug 106 to the flange a1053 of the sleeve 105. At this time, the installation is completed. After the concrete wall is poured, the plug 106, the sleeve 105, and the inner shaft 101 can be removed in sequence. It should be noted here that by adjusting the positions of the positioning ring 102 and the locking nut 104, the position of the inner support block 103 can be adjusted to be vertically aligned with the building formwork 30 to support the staggered part between the sleeve 20 and the building formwork 30.
