Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a pre-embedded sleeve fixer. Background Technology

[0002] Pre-embedded sleeves are pipes or sleeves that are pre-installed during building construction. They provide a fixed position and passage for subsequent pipe installation. Therefore, it is necessary to pre-embed and fix the sleeves during construction. However, since it is difficult to accurately locate the position of the pre-embedded sleeves during construction, a lot of effort is often required to drill holes later, which increases construction costs, reduces the quality of structural construction, and also poses a risk of leakage at the drilled holes.

[0003] A technical solution disclosed in Chinese utility model patent document CN221374789U, entitled "An Improved Pre-embedded Sleeve Fixing Assembly," involves a fixing seat detachably mounted on a template via a fastening assembly or fastening screws. A limiting pressure plate is installed on the top of the pre-embedded sleeve to compress, limit, and seal it. An adjustable support rod passes sequentially from top to bottom through the limiting pressure plate, the pre-embedded sleeve, and the fixing seat, and is detachably connected to the template as a whole. Its end is secured with a fastening nut. Fasteners are screwed onto the top of the adjustable support rod and positioned above the limiting pressure plate. This utility model offers simple and quick installation and disassembly, and the molding quality is good after the template is removed.

[0004] However, the aforementioned pre-embedded sleeve fixing assembly lacks a positioning structure between the top fixing plate and the pre-embedded sleeve during use. After connecting the top fixing plate and the pre-embedded sleeve, it is difficult to ensure that the hole in the middle for the adjustable support rod to pass through corresponds to the fixing hole in the lower fixing seat. This hinders the connection between the adjustable support rod and the lower fixing hole, and the positioning process of the upper limiting pressure plate is time-consuming and laborious. Therefore, we propose a pre-embedded sleeve fixing device. Utility Model Content

[0005] The purpose of this utility model is to provide a pre-embedded sleeve fixer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pre-embedded sleeve fixing device, comprising a bottom fixing component and a top fixing plate, wherein a fixing screw is fixedly assembled between the bottom fixing component and the top fixing plate, a fixing nut is assembled on the outer side wall of the fixing screw, a positioning hole is provided at the center of the top fixing plate, and a positioning component is assembled inside the top fixing plate;

[0007] The positioning component includes a mounting groove, which is formed inside a top fixed plate. A fixed shaft is fixedly mounted inside the mounting groove. A movable frame is sleeved on the outer side wall of the fixed shaft. A positioning block is fixedly connected to the bottom of the movable frame. A spring is fixedly mounted between the movable frame and the mounting groove.

[0008] Preferably, the number of mounting slots is at least three, and the three mounting slots are evenly distributed in a circle with the positioning hole as the center.

[0009] Preferably, a handle block is fixedly connected to the top of the mobile frame.

[0010] Preferably, the bottom fixing component includes a fixing body, a fixing screw hole is provided at the center of the fixing body, an assembly hole is provided inside the fixing body, an auxiliary fixing block is integrally formed on the side wall of the fixing body, and a fixing screw is installed in the assembly hole.

[0011] Preferably, the number of auxiliary fixing blocks is at least four, and the four auxiliary fixing blocks are evenly distributed in a circle around the center of the fixing body. An auxiliary support block is fixedly connected between the auxiliary fixing blocks and the fixing body.

[0012] Preferably, the top of the fixing screw is symmetrically fixed with handles on the left and right sides.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: A pre-embedded sleeve fixer, compared with traditional pre-embedded sleeve fixing components, is innovative in that a positioning component is embedded in the top fixing plate. This positioning component can position the top fixing plate when it is connected to the top of the pre-embedded sleeve. Specifically, the positioning hole in the middle of the top fixing plate can be aligned with the fixing screw hole in the bottom fixing component, thereby allowing the subsequent fixing screw to connect more accurately to the bottom fixing component. Using this utility model can significantly improve the connection efficiency between the top fixing plate and the bottom fixing component, and make the assembly process of the top fixing plate simpler and less labor-intensive.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This utility model provides a technical solution: a pre-embedded sleeve fixer, including a bottom fixing member 1 and a top fixing plate 2. A fixing screw 3 is assembled between the bottom fixing member 1 and the top fixing plate 2. A handle 8 symmetrically distributed on the left and right sides is welded and fixed to the top of the fixing screw 3. The handle 8 facilitates the rotation of the fixing screw 3. A fixing nut 4 is screwed to the outer wall of the fixing screw 3. Through the cooperation of the bottom fixing member 1 and the top fixing plate 2, the pre-embedded sleeve can be fixed to the surface of the pouring template. During the subsequent concrete pouring process, the pre-embedded sleeve can improve the stability of its position fixation with the pouring template and avoid the pre-embedded sleeve from shifting its pre-embedded fixing position during the concrete pouring process.

[0023] The bottom fixing component 1 is made of hard plastic and can be left in the pre-embedded sleeve after use. The use of plastic for the bottom fixing component 1 makes it have a low usage cost. The top fixing plate 2 is made of metal material and can be recycled and reused after the pre-embedded sleeve is fixed.

[0024] like Figure 1 and Figure 2As shown, the bottom fixing component 1 includes a fixing body 11, which is circular. A fixing screw hole 12 for connecting with the fixing screw 3 is provided in the middle of the fixing body 11. An assembly hole 13 is provided on the top of the fixing body 11. The number of assembly holes 13 is at least four. The four assembly holes 13 are evenly distributed in a circle with the fixing screw hole 12 as the center. The assembly holes 13 are used for assembling the fixing screw 5. The fixing body 11 can be connected and fixed to the casting template by fixing the fixing screw 5. An auxiliary fixing block 14 is integrally formed on the side wall of the fixing body 11. The number of auxiliary fixing blocks 14 is at least four. The auxiliary fixing blocks 14 are evenly distributed in a circle with the center of the fixing body 11. By setting the auxiliary fixing blocks 14, the overall height of the bottom fixing component 1 can be increased, thereby strengthening the fixing effect of the bottom fixing component 1 on the bottom of the pre-embedded sleeve after the pre-embedded sleeve is sleeved on the bottom fixing component 1.

[0025] An auxiliary support block 15 is integrally formed between the side wall of the auxiliary fixing block 14 and the top of the fixing body 11. By setting the auxiliary support block 15, the overall strength between the auxiliary fixing block 14 and the fixing body 11 can be strengthened, and the deformation of the auxiliary fixing block 14 when the bottom fixing part 1 supports and fixes the pre-embedded sleeve can be avoided, which would affect its positioning effect on the pre-embedded sleeve. The overall size of the bottom fixing part 1 can be prefabricated according to the pipe diameter of the pre-embedded sleeve to meet the usage requirements of using pre-embedded sleeves with different pipe diameters.

[0026] like Figure 1 and Figure 3 As shown, a positioning hole 6 is provided at the center of the top fixing plate 2. The positioning hole 6 is used to fix the screw 3 through, and a positioning component 7 is installed inside the top fixing plate 2. By setting the positioning component 7, the top fixing plate 2 and the pre-embedded sleeve can be positioned, so that the positioning hole 6 can correspond to the position of the fixing screw hole 12 in the bottom fixing component 1 below, thereby facilitating the connection and fixation of the fixing screw 3 and the fixing screw hole 12.

[0027] The positioning component 7 includes an L-shaped mounting groove 71, which is located within the top fixed plate 2. There are three mounting grooves 71, which are evenly distributed around the positioning hole 6. A fixed shaft 72 is welded and fixed within the mounting groove 71. A movable frame 73, also L-shaped, is fitted onto the outer wall of the fixed shaft 72. The movable frame 73 can slide within the mounting groove 71 via the fixed shaft 72. A positioning block 74 is integrally formed at the bottom of the movable frame 73. A spring 75 is fixedly mounted between the movable frame 73 and the mounting groove 71 to support the movable frame 73. A handle block 76 is integrally formed at the top of the movable frame 73 to facilitate the movement of the movable frame 73 within the mounting groove 71.

[0028] The top fixing plate 2 has higher adaptability and can be used with pre-embedded sleeves of different pipe diameters. Since the bottom fixing part 1 is adapted to the size of the pre-embedded sleeve it is connected to, when the pre-embedded sleeve is fitted onto the outer wall of the bottom fixing part 1, the fixing screw hole 12 will be located in the middle of the pre-embedded sleeve. Then, when connecting the top fixing plate 2 to the top of the pre-embedded sleeve, the handle block 76 is pushed inward at the same time to insert the three sets of positioning blocks 74 into the pre-embedded sleeve. After releasing the handle block 76, since the three sets of positioning blocks 74 are triangularly distributed, when the positioning block 74 is in contact with the inner wall of the pre-embedded sleeve, the compression of the spring 75 by each corresponding moving frame 73 is the same. At this time, the positioning hole 6 can be positioned in the center of the pre-embedded sleeve so that it corresponds to the position of the fixing screw hole 12 below, which makes it easy to assemble the fixing screw 3 downward and connect and fix it to the bottom fixing part 1.

[0029] Working principle: such as Figure 4 , Figure 5 and Figure 6 As shown, when using this utility model to limit and fix the embedded sleeve, firstly, the bottom fixing part 1, which is adapted to the size of the embedded sleeve, is fixedly assembled on the surface of the casting template by fixing screws 5. Then, the embedded sleeve is sleeved on the outer wall of the bottom fixing part 1. At this time, the fixing screw hole 12 in the middle of the bottom fixing part 1 is located at the center of the embedded sleeve. Then, the top fixing plate 2 is fixedly connected to the top of the embedded sleeve. The handle block 76 is pushed inward to move the positioning block 74 inward. After the positioning block 74 is inserted into the inner wall of the top of the embedded sleeve, releasing the handle block 76 will cause the moving frame 73 to be driven by the elastic force from the spring 75 to move the positioning block 74. The positioning hole 6 is aligned with the inner wall of the pre-embedded sleeve, and the positions of the positioning hole 6 and the fixing screw hole 12 are corresponding. Then, the fixing screw 3 is passed through the positioning hole 6, and the fixing screw 3 is rotated by the handle 8 to connect and fix its bottom with the fixing screw hole 12. Then, the fixing nut 4 is screwed on. The fixing nut 4 is located above the top fixing plate 2. The fixing nut 4 can lock the top fixing plate 2 and the pre-embedded sleeve in place, thereby fixing the pre-embedded sleeve to the pouring template below, improving the stability of the position of the pre-embedded sleeve after the concrete is poured. After the concrete has solidified, the top fixing plate 2 can be disassembled and reused, reducing the waste of resources.
