Description

Technical Field

[0001] The invention relates to the technical field of building embedded parts, and in particular to an assembled building embedded part. Background Art

[0002] Embedded parts (prefabricated embedded parts) are components that are pre-installed (buried) in concealed projects. They are components placed during structure casting and are used for overlap when building superstructures to facilitate the installation and fixation of external engineering equipment foundations. Embedded parts are mostly made of metal, such as steel bars or cast iron, and can also be made of non-metallic rigid materials such as wood and plastic.

[0003] The existing embedded parts are basically an integrated structure, which can be understood as a part of the embedded part located inside the building, while the other part is exposed from the surface of the building. The part located inside the building is fixedly connected to the steel bars by welding, binding, etc., while the part exposed on the surface is a structure for external connection. Therefore, during the construction process, if the embedded parts are exposed from the upper surface of the building, there is no need to use building formwork here, but it is necessary to pay attention to avoid touching during the pouring process. If the embedded parts are exposed from the side walls of the building, when using the building formwork, it is necessary to open holes in the building formwork. In actual situations, the holes between the embedded parts and the building formwork cannot fit completely, so the gap between the two needs to be filled before pouring. In the subsequent process, the surface quality of the building at the embedded parts does not meet the standards and needs further correction, so the use of the embedded parts increases the complexity of the construction. The integrated structure of the embedded parts also has a solidified connection method. Summary of the invention

[0004] In order to solve the above problems, the present invention discloses an assembled building embedded part, including an assembly part and an embedded part, the assembly part includes an expansion tube, a side wall of one end of the expansion tube is provided with a plurality of openings at equal angles, a frustum body is provided at one end of the expansion tube, and the frustum body is provided close to the opening, a screw is provided at one end of the frustum body, and the screw extends to the inside of the expansion tube, the inside of the expansion tube is fixedly connected to a cross bar, the screw is inserted and threadedly connected to the cross bar, and the inner wall of the other end of the expansion tube is provided with a thread. The structure of the assembly part is similar to the deformation structure of the expansion bolt, specifically, by rotating the screw, the frustum body is pulled into the inside of the expansion tube, so that the opening area is deformed outward, and after the adapter is fixed to the embedded part, a rod with a thread at the end can be used to cooperate with the threaded section.

[0005] The embedded part includes a fixing plate, a connecting pipe is fixedly connected to the middle of the fixing plate, one end of the connecting pipe is set as an arc segment, the expansion tube is fitted inside the connecting pipe, and a stop cover is buckled at the end of the arc segment. When the assembly part is placed inside the embedded part and one end is deformed, and the deformation structure is located exactly at the arc segment, it fits tightly with the inner wall of the arc segment after the expansion is completed, so that the assembly part is firmly fixed on the embedded part. With this arrangement, there is no need to set a connecting ear on the fixing plate. During the casting process, the fixing plate can be directly fitted with the inner wall of the building formwork without reserving openings on the building formwork, which improves the convenience of construction and makes the building surface smooth after casting.

[0006] Preferably, a support sleeve is sleeved on the expansion pipe, and the outer diameter of the support sleeve is equal to the inner diameter of the connecting pipe. The outer diameter of the expansion pipe is smaller than the inner diameter of the connecting pipe, and the maximum diameter of the frustum body is exactly equal to the inner diameter of the connecting pipe, which is used to ensure that the inner pipe of the connecting pipe is inserted into the connecting pipe, and the frustum body can be moved to achieve deformation of the expansion pipe, and the support sleeve is provided to prevent the expansion pipe from tilting.

[0007] Preferably, the lower side wall of the fixing plate is fixedly connected with a lower fixing rod, and the lower fixing rod is in an "L" shape, and the upper side wall of the fixing plate is fixedly connected with an upper fixing rod, and the upper fixing rod is hook-shaped. The lower fixing rod and the upper fixing rod are connected to the steel cage to achieve fixation with the embedded parts.

[0008] Preferably, the end of the expansion tube is fixedly connected to a first connecting plate, and a reserved hole is provided in the middle of the first connecting plate, that is, the reserved hole allows the screw to have space for operation, thereby pulling the frustum body.

[0009] Preferably, the first connecting plate is provided with a first connecting hole, and a connecting member such as a bolt is used to pass through the first connecting hole, which provides a second connecting method relative to the above.

[0010] Preferably, a second connecting plate is vertically fixedly connected to the first connecting plate, and a second connecting hole is provided on the second connecting plate. A connecting member such as a bolt is passed through the second connecting hole, which provides a third connection method relative to the above.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The embedded parts are divided into embedded parts and assembly parts, and the fixing plates of the embedded parts can be set flush with the building surface, which not only improves the beauty of the wall but also facilitates construction.

[0013] 2. The assembly parts are stuck inside the embedded parts through deformation. At the same time, the assembly parts can be matched with different structures according to the needs of installation, so as to obtain a variety of connection methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. Example

[0023] like Figure 1 to Figure 2As shown, an assembled building embedded part includes an assembly part 1 and an embedded part 2, that is, the embedded part 2 is pre-cast in the building body, and the assembly part 1 serves as a bridge between the embedded part 2 and the external connecting part. The assembly part 1 includes an expansion tube 13, and a side wall of one end of the expansion tube 13 is provided with a plurality of openings 15 at equal angles, so that the end of the expansion tube 13 at this end is easier to deform. A frustum body 17 is provided at one end of the expansion tube 13, and the smaller end of the frustum body 17 is located inside the expansion tube 13, and the frustum body 17 is arranged close to the opening 15. When the frustum body 17 is forced to enter the interior of the expansion tube 13, the opening 17 area on the expansion tube 13 deforms outward. A screw 16 is provided at one end of the frustum body 17, and the screw 16 and the frustum body 17 are rotationally connected, and the screw 16 can pull the frustum body 17 to move axially, and the screw 16 extends to the inside of the expansion tube 13, and the inside of the expansion tube 13 is fixedly connected to the cross bar 14, and the screw 16 is inserted and threadedly connected to the cross bar 14. When the screw 16 is rotated, the frustum body 17 can be pulled to move, thereby realizing the deformation of the expansion tube 13. A threaded section 12 is provided on the inner wall of the other end of the expansion tube 13 for connecting an external rod, and a thread is provided on the end side wall of the dry frame, so as to realize the fixed connection between the external rod and the assembly 1 by high thread matching.

During pouring, the front side of the fixing plate 21 can be tightly fitted with the inner wall of the building template without opening a hole in the building template for the fixing plate 21, which is convenient for construction. A connecting pipe 25 is fixedly connected to the middle part of the fixing plate 21, and a through hole is also provided in the middle part of the fixing plate 21. One end of the connecting pipe 25 is provided as an arc segment 24. Specifically, the end of the connecting pipe 25 is expanded, and the expansion tube 13 is fitted inside the connecting pipe 25. Then, the frustum body 17 is pulled to move, so that the expansion tube 13 is deformed and tightly fitted with the inner wall of the arc segment 24, so that the assembly part 1 and the embedded part 2 can be fixedly connected. In addition, this connection method can also control the rotation angle of the axial fit between the assembly part 1 and the embedded part 2. A stop cover 23 is provided at the end of the arc segment 24 to prevent concrete from entering the inside of the connecting pipe 25 during pouring.

[0025] like Figure 2 As shown, a support sleeve 11 is sleeved on the expansion tube 13, and the outer diameter of the support sleeve 11 is equal to the inner diameter of the connecting tube 25.

[0026] The lower side wall of the fixing plate 21 is fixedly connected with a lower fixing rod 22, and the lower fixing rod 22 is in an "L" shape. The upper side wall of the fixing plate 21 is fixedly connected with an upper fixing rod 26, and the upper fixing rod 26 is hook-shaped, which is convenient for hanging on the steel cage. The lower fixing rod 22 and the upper fixing rod 26 are fixed on the steel cage by welding or binding, thereby realizing the positioning of the embedded part 2. Example

Compared with Example 1, a second connecting method is provided, specifically using connecting parts such as bolts to pass through the first connecting hole 110 from the back side of the first connecting plate 19 to achieve a fixed connection with an external connecting part. Example
