Description

Technical Field

[0001] This utility model relates to the field of wall sleeve technology, specifically a simple wall sleeve. Background Technology

[0002] When a building settles, there will be relative displacement between the wall and the pipe. The gap reserved between the through-wall sleeve and the pipe can make up for this displacement difference, reduce the pressure of building settlement on the pipe, and prevent the pipe from breaking or twisting due to uneven settlement.

[0003] Most existing sleeves are installed by placing a steel bar at the bottom elevation of the sleeve on both sides of the steel mesh and welding it to the vertical steel bar of the shear wall. The sleeve is then placed on the welded steel bar and spot-welded to the top of the steel bar using an electric welding machine. At the same time, care should be taken to control the welding current and time during spot welding to avoid burning the steel bar and the sleeve.

[0004] The aforementioned sleeve has some problems in use. It is fixed by welding, which requires an electric welding machine. Furthermore, it is not easy to control the current and time during welding, which may burn the steel bars and the sleeve. In addition, using the welding machine requires running a cable from the temporary power source to the work area, which is quite cumbersome. Utility Model Content

[0005] The purpose of this utility model is to provide a simple through-wall sleeve to solve the problems mentioned in the background art, which require welding for fixing. Welding requires an electric welding machine, and the current and time cannot be well controlled during welding, which may burn the steel bars and the sleeve. In addition, using a welding machine requires running a cable from a temporary power source to the work area, which is quite cumbersome.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A simple through-wall sleeve includes a sleeve body, with fixing rings fitted at both ends of the sleeve body. Both sides of the two sets of fixing rings are provided with fixing components for fixing the sleeve body to prevent it from shaking. A lifting component for lifting the sleeve body upward is provided at the bottom of one end of the fixing ring. The top of the two sets of fixing rings is connected to a connecting rod through a connector. A horizontally arranged fixing rod is welded to the top of the connecting rod.

[0008] As a preferred technical solution, the fastener includes a first nut fixedly installed on both sides of one end of the fixing ring, and the inner cavity of each of the two sets of first nuts is threaded with a first bolt. The ends of the two sets of first bolts are respectively threaded through the corresponding side of the first nut and abut against the surface of the sleeve body.

[0009] As a preferred technical solution, the lifting assembly includes a second nut fixedly installed at the bottom of one end of the fixing ring. The inner cavity of the second nut is threaded with a lifting bolt. The end of the lifting bolt is threaded upward through the inner cavity of the second nut and abuts against the bottom surface of the sleeve body.

[0010] As a preferred technical solution, the connector includes an external thread located at the lower end of the connecting rod, a threaded hole is provided at the top of the fixing ring, and the lower end of the connecting rod is threadedly connected to the inner cavity of the threaded hole through the external thread.

[0011] As a preferred technical solution, a number of grooves are formed on one side surface of the fixing rod, and the number of grooves are arranged linearly and at equal intervals.

[0012] As a preferred technical solution, protective caps are fitted onto both ends of the sleeve body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of a fixing ring, connecting rod, and fixing rod, with the fixing rod tied to the vertical reinforcing bars of the steel mesh and the fixing ring connected by a connector, allows the sleeve body to be placed in the inner cavity of the fixing ring and then fixed by the fixing component. It eliminates the need for a welding machine to fix the sleeve body, greatly simplifying the construction process, making the operation convenient and quick, significantly improving construction efficiency, and reducing construction costs and safety risks. It can better adapt to various complex construction site environments and construction progress requirements, and meet the installation and use needs of the sleeve body under various complex working conditions.

[0015] 2. By setting up a fixing component, the pressure on the sleeve body can be easily adjusted by rotating the first bolt to adapt to sleeve bodies of different sizes and materials, thereby improving the flexibility and adaptability of fixing. At the same time, when the first bolts on different sides are tightened or loosened in a targeted manner, the pressure difference between the two sides is used to push the sleeve body to move slowly to the required position. Then, the first bolts on both sides are tightened evenly to fix it, thereby making lateral adjustments to the sleeve body and ensuring that the sleeve body is in the correct position.

[0016] 3. This utility model, through the setting of the lifting component, can raise or lower the sleeve body according to actual needs, adjust the height of the sleeve body to ensure that the sleeve body is in the correct position, and the adjustment process is stable, controllable, and highly accurate.

[0017] 4. By setting the groove, this utility model can increase the contact area with the vertical steel bars when binding them, thus making the structure more stable after binding. It effectively avoids relative displacement between the fixing rod and the steel bars due to external forces during construction, and further improves the reliability of the entire device when it is used with the steel structure.

[0026] 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.

[0027] Please see Figure 1-3This embodiment provides a simple through-wall sleeve, including a sleeve body 100. Both ends of the sleeve body 100 are fitted with fixing rings 101. Both sides of the two sets of fixing rings 101 are provided with fixing components for fixing the sleeve body 100 and preventing it from shaking. A lifting component for lifting the sleeve body 100 is provided at the bottom of one end of each fixing ring 101. The tops of both sets of fixing rings 101 are connected to connecting rods 103 via connectors. A horizontally arranged fixing rod 104 is welded to the top of the connecting rod 103. Through the arrangement of the fixing rings 101, connecting rods 103, and fixing rods 104, the sleeve body 100 is fixed... The fixed rod 104 is tied to the vertical reinforcing bars of the steel mesh at the required position and connected to the fixing ring 101 through the connector. Then, the sleeve body 100 is simply placed in the inner cavity of the fixing ring 101 and fixed with the fastener. There is no need to use a welding machine to fix the sleeve body 100, which greatly simplifies the construction process, makes the operation convenient and quick, greatly improves the construction efficiency, and also reduces the construction cost and safety risks. It can better adapt to various complex construction site environments and construction progress requirements, and meet the installation and use requirements of the sleeve body 100 under various complex working conditions.

[0028] The diameter of the fixing ring 101 is larger than the diameter of the sleeve body 100. The sleeve body 100 retains a certain amount of space within the fixing ring 101 to facilitate subsequent position adjustments.

[0029] The fastener includes first nuts 200 fixedly installed on both sides of one end of the fixing ring 101. The inner cavities of the two sets of first nuts 200 are threaded with first bolts 201. The ends of the two sets of first bolts 201 are threaded through the corresponding first nuts 200 and abut against the surface of the sleeve body 100. By setting the fastener, rotating the first bolts 201 can easily adjust the pressure on the sleeve body 100 to adapt to sleeve bodies 100 of different sizes and materials, thus improving the flexibility and adaptability of the fastener. At the same time, when the first bolts 201 on different sides are tightened or loosened in a targeted manner, the pressure difference between the two sides is used to push the sleeve body 100 to move slowly to the required position. Then, the first bolts 201 on both sides are tightened evenly to fix it, thereby adjusting the sleeve body 100 laterally and ensuring that the sleeve body 100 is in the correct position.

[0030] The lifting assembly includes a second nut 300 fixedly installed at the bottom of one end of the fixing ring 101. The inner cavity of the second nut 300 is threaded with a lifting bolt 301. The end of the lifting bolt 301 is threaded upward through the inner cavity of the second nut 300 and abuts against the bottom surface of the sleeve body 100. By setting up the lifting assembly, the sleeve body 100 can be raised or lowered according to actual needs, and the height of the sleeve body 100 can be adjusted to ensure that the sleeve body 100 is in the correct position. The adjustment process is smooth, controllable, and highly accurate.

[0031] The connector includes an external thread 400 located at the lower end of the connecting rod 103, and a threaded hole 401 at the top of the fixing ring 101. The lower end of the connecting rod 103 is threaded into the inner cavity of the threaded hole 401 through the external thread 400. With the connector, the external thread 400 is connected to the threaded hole 401 at the top of the fixing ring 101. The installation and disassembly process is simple and quick, which is convenient for assembly on the construction site. At the same time, the threaded connection has good stability and can ensure a reliable connection between the connecting rod 103 and the fixing ring 101.

[0032] The fixing rod 104 has several sets of grooves 402 on one side surface. These grooves 402 are arranged linearly and at equal intervals. By setting the grooves 402, the contact area with the vertical steel bars can be increased when binding with them, thus making the structure more stable after binding. This effectively avoids relative displacement between the fixing rod 104 and the steel bars due to external forces during construction, further improving the reliability of the entire device when it is used in conjunction with the steel structure.

[0033] The casing 100 is equipped with protective caps 102 at both ends. The protective caps 102 can effectively prevent concrete from entering the casing 100 during concrete pouring and avoid causing blockage inside the casing 100.

[0034] Working principle;

[0035] First, the bottom of the connecting rod 103 is threaded into the inner cavity of the threaded hole 401 at the top of the fixing ring 101 through the external thread 400. Then, the fixing rod 104 is tied to the vertical steel bar of the steel mesh, the sleeve body 100 is placed in the inner cavity of the fixing ring 101, and the first bolt 201 is tightened inward at the same time to fix the sleeve body 100.

[0036] When the height of the sleeve body 100 is lower than the correct position, loosen the first bolt 201 and then tighten the lifting bolt 301 upward to lift the sleeve body 100 upward until it reaches the correct position, thereby achieving precise adjustment of the height of the sleeve body 100. When the adjustment is complete, tighten the first bolt 201 inward to fix the sleeve body 100.

[0037] When the casing 100 shifts laterally, move the casing 100 to one side, tighten the first bolt 201 on that side, and at the same time loosen the first bolt 201 on the other side appropriately. Use the pressure difference between the two sides to push the casing 100 to move. After reaching the predetermined position, tighten the first bolts 201 on both sides evenly to prevent the casing 100 from swaying horizontally and complete the lateral position adjustment.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
