Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a building construction pipeline fixing device. Background Technology

[0002] In order to protect the overall structure of the building and avoid secondary damage to the structure caused by subsequent pipeline construction, and to improve construction quality and efficiency as well as ensure waterproof performance, pipelines are usually pre-embedded. This means that the sleeve is poured into the concrete during construction to fix the pre-embedded sleeve.

[0003] In existing technologies, sleeves are typically fixed using bolts inserted into fixing holes at the bottom of the sleeve. The sleeve is then fixed to the formwork via these bolts. To ensure stability after fixing, multiple fixing holes are usually provided around the circumference of the sleeve's bottom. However, to ensure accurate sleeve embedding, the reinforcement cage influences the placement of some fixing holes, requiring some of these holes to be moved below the cage. This makes it difficult to fix the sleeve, and improper operation can easily cause sleeve misalignment, obstructing subsequent straight-line conduction between upper and lower layers. Furthermore, existing fixing methods require bolts that cannot be removed, causing significant damage to the formwork and affecting its reusability. Therefore, there is an urgent need for a construction pipeline fixing device that is unaffected by the position of the reinforcement cage, allows for rapid sleeve positioning and installation, and minimizes damage to the formwork. Utility Model Content

[0004] The purpose of this utility model is to provide a building construction pipeline fixing device with a simple structure and easy operation. It is not affected by the position of the steel cage, can quickly realize the positioning and installation of the sleeve, has a high reusability, causes less damage to the formwork, reduces material waste, and saves construction costs.

[0005] The present invention adopts the following technical solution:

[0006] A building construction pipeline fixing device includes a central fixing plate, a plurality of collars with progressively increasing diameters are provided on the outer side of the fixing plate, and two adjacent collars are detachably connected to the fixing plate; a through hole is provided in the middle of the fixing plate, and a threaded sleeve coaxial with the through hole is provided at the bottom of the fixing plate, and a fixing screw is provided in the threaded sleeve.

[0007] Preferably, the cross-section of the fixing plate is circular, and the cross-section of the collar is annular.

[0008] Preferably, the through hole is a countersunk hole.

[0009] Preferably, a connecting block is slidably provided on the collar, and connecting grooves are provided on the other collars and the fixing plate, except for the collar located at the outermost end.

[0010] Preferably, the connecting block is slidably disposed at the bottom of the collar, and the connecting groove is correspondingly disposed at the bottom of the collar and the fixing plate.

[0011] Preferably, the bottom of the connecting block is flush with the bottom surface of the collar.

[0012] Preferably, in the initial state, the outer end of the collar is flush with the outer surface of the collar, while the inner side extends from the inner side of the collar, and the extended portion matches the length of the corresponding connecting groove.

[0013] Preferably, the top of the fixing screw is provided with an outer adjusting cap, and the top of the outer adjusting cap is recessed to form an outer adjusting groove.

[0014] Preferably, the fixing screw has a hollow internal structure and extends through from the outer adjustment groove to the bottom of the fixing screw; the fixing screw has an extension screw with an internal thread, the extension screw has an inner adjustment cap at its top, and the inner adjustment cap has an inner adjustment groove at its top.

[0015] Preferably, in its initial state, the tip of the extension screw extends from the bottom of the fixing screw, and a limiting plate is provided at the top of the tip, the diameter of which matches the diameter of the fixing screw.

[0016] Compared with the prior art, the advantages of this utility model are as follows: This utility model can achieve the positioning and installation of the sleeve by placing the fixing plate on the top of the sleeve to be pre-embedded and connecting it with the template below the reinforcing cage using the fixing screws on the fixing plate. Since the fixing screws pass through the middle of the sleeve and are not affected by the reinforcing cage, the operation is simple and quick. In addition, the connection with the template only by fixing screws can effectively reduce the degree of damage to the template. Moreover, the fixing screws are located at the top of the sleeve and can be removed after the concrete has solidified, which can be reused and save construction costs.

[0019] Figure 2 This is a bottom view of the fixing plate in an embodiment of this application;

[0020] Figure 3This is a cross-sectional view of the fixing screw in an embodiment of this application;

[0021] Figure 4 This is a schematic diagram of the structure when the fixing plate and the sleeve are connected in an embodiment of this application. Detailed Implementation

[0022] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:

[0023] like Figures 1 to 4 As shown, the present invention discloses a building construction pipeline fixing device, comprising a central fixing plate 1, with multiple collars 2 of progressively increasing diameter on the outer side of the fixing plate 1, and detachable connections between adjacent collars 2 and the fixing plate 1, to accommodate fixing of sleeves 5 of various diameters, thus expanding the applicability of the present invention. The inner diameter of the outer large collar 2 matches the outer diameter of the inner small collar 2, and the inner diameter of the inner small collar 2 matches the outer diameter of the central fixing plate 1, achieving a tight connection. A through hole 6 is provided in the center of the fixing plate 1, and a threaded sleeve 3 coaxial with the through hole 6 is provided at the bottom of the fixing plate 1. A fixing screw 4 is threaded inside the threaded sleeve 3. By controlling the rotation of the fixing screw 4 to make it contact and connect with the template at the bottom of the reinforcing cage, the sleeve 5 can be fixed. This avoids the adverse effects of the reinforcing cage on the fixing of the sleeve 5, ensures the accuracy of the sleeve 5 fixing, and effectively reduces damage to the template by connecting only to the template through the fixing screw 4. Furthermore, the fixing screw 4 can be disassembled after the concrete has set, allowing for reuse and reducing construction costs.

[0024] Furthermore, in this embodiment, the cross-section of the fixing plate 1 is circular, and the cross-section of the collar 2 is annular, so as to match the shape of the sleeve 5, while reducing the adverse effects on the concrete pouring surface and improving the flatness of the concrete pouring surface. When using this utility model, the dimensions of the fixing plate 1 or the fixing plate 1 connected to the collar 2 can match the outer radial direction of the sleeve 5, so as to facilitate subsequent disassembly operations. Preferably, in this embodiment, the through hole 6 is preferably set as a countersunk hole, so as to accommodate the outer adjusting cap 7 at the end of the fixing screw 4, ensuring that the top of the fixing plate 1 is flush under normal conditions; wherein the top of the outer adjusting cap 7 is recessed to form an outer adjusting groove 8, so that a driving tool, such as an Allen wrench, can be inserted into it to control its rotation.

[0025] Furthermore, in this embodiment, the fixing screw 4 has a hollow internal structure and extends from the outer adjusting groove 8 to the bottom of the fixing screw 4. An extension screw 9 is threaded internally on the fixing screw 4, and an inner adjusting cap 10 is provided at the top of the extension screw 9, with an inner adjusting groove at the top of the inner adjusting cap 10. The extension screw 9 extends the length of the fixing screw 4 to accommodate the use of a longer sleeve 5, while avoiding excessive length of the fixing screw 4. When matching a shorter sleeve 5, excessive length would be required to pass through the template to ensure the top of the fixing plate 1 is flush, increasing the risk of damage to the template. Preferably, in its initial state, the tip 11 of the extension screw 9 extends from the bottom of the fixing screw 4, and a limiting plate 12 is provided at the top of the tip 11. The diameter of the limiting plate 12 matches the outer diameter of the fixing screw 4, and the bottom of the fixing screw 4 is planar. This arrangement enhances the integration of the fixing screw 4 and the extension screw 9, ensuring optimal performance.

[0026] Furthermore, a connecting block 13 is slidably disposed on the collar 2. Except for the outermost collar 2, the other collars 2 and the fixing plate 1 are all provided with connecting grooves 14. The connecting block 13 is as follows: Figure 1 The collar 2 has protrusions on both sides, and a groove matching its shape is provided on the collar 2. The connecting block 13 can slide and adjust inward and outward along the groove. In use, first move the connecting block 13 outward, then put the collar 2 with a larger diameter on the outside of the collar 2 with a smaller diameter, and then slide the connecting block 13 inward so that the connecting block 13 is placed in the connecting groove 14 to realize the connection between the collars 2 and between the collar 2 and the fixing plate 1. Preferably, the connecting block 13 is slidably disposed at the bottom of the collar 2, and the connecting groove 14 is correspondingly disposed at the bottom of the collar 2 and the fixing plate 1. The bottom of the connecting block 13 is flush with the bottom surface of the collar 2. After the connecting block 13 is slidably disposed in the connecting groove 14, its bottom is flush with the bottom of the collar 2 or the fixing plate 1 where the connecting groove 14 is located, so as to ensure tight contact with the sleeve 5 during use. In addition, in the initial state, the outer end of the collar 2 is flush with the outer surface of the collar 2, while the inner side extends from the inner side of the collar 2, and the extended part matches the length of the corresponding connecting groove 14, so as to achieve a tight connection between the collars 2 and between the collar 2 and the fixing plate 1, while ensuring the flatness of the outermost collar 2 after connection, which facilitates the pouring of concrete.

[0027] In use, the sleeve 5 is first placed at the designated position on the template. Then, different diameter collars 2 are installed according to the diameter of the sleeve 5. Finally, the fixing plate 1 and collar 2 are placed on the top of the sleeve 5, and the fixing screws 4 are adjusted to connect with the template. After the concrete is poured and solidified, when dismantling the formwork, the fixing screws 4 can be removed first, and then the fixing plate 1 can be removed. This allows for reuse and seals the top of the sleeve 5, preventing concrete from falling into the sleeve 5 and blocking it during the pouring process. The structure is simple, easy to use, and highly practical.
