Description

Technical Field

[0001] This utility model belongs to the field of building component technology, and in particular relates to a rigid mechanical connection structure for pre-embedded steel bars in prefabricated building components. Background Technology

[0002] With the advancement of industrialization and modernization in the construction industry, prefabricated buildings have been widely adopted due to their advantages such as fast construction speed, controllable quality, and environmental friendliness and energy conservation. In this context, achieving reliable connections between prefabricated components has become a critical issue. Traditional steel reinforcement connection methods include welding and bolting, but these methods suffer from problems such as complex construction and difficulty in guaranteeing quality. Especially under extreme conditions such as earthquakes, these connection methods may not meet the seismic resistance requirements of the structure.

[0003] When using existing equipment, the number of embedded parts required for different construction requirements varies, making it inconvenient to adjust the connection dimensions. At the same time, air can easily be incorporated during the fixing process, resulting in poor fixing effect. Therefore, we propose a rigid mechanical connection structure for embedded steel bars in prefabricated building components. Summary of the Invention

[0004] The purpose of this utility model is to provide a rigid mechanical connection structure for pre-embedded steel bars in prefabricated building components. Through a fixing mechanism and a vibration mechanism, it solves the problem that it is inconvenient to adjust the connection size due to the different number of pre-embedded parts required for different construction requirements, and that air can easily be incorporated during the fixing process, resulting in poor fixing effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a rigid mechanical connection structure for pre-embedded steel bars in prefabricated building components, including a support mechanism. The support mechanism includes a fixed frame, with a fixed column fixedly connected to the outer wall of the fixed frame. A fixing mechanism is provided on the outer wall of the fixed frame, and the fixing mechanism includes a hollow tube. An extension rod is slidably connected to the inner wall of the hollow tube. A vibration mechanism is provided on the outer wall of the fixed frame, and the vibration mechanism includes a connecting block. A positioning hole is opened on the inner wall of the connecting block, and a motor is fixedly connected to the inner wall of the positioning hole.

[0007] With the above technical solution, when inserting a large number of embedded parts, the extension rod slides on the inner wall of the hollow tube, which facilitates increasing the fixed area.

[0008] Furthermore, the outer wall of the fixed frame is fixedly connected with several extension tubes, and the inner wall of the extension tubes is provided with limiting holes.

[0009] By using the above technical solution, a limiting hole is opened on the inner wall of the extension tube to prevent shaking when the operator rotates the bidirectional threaded rod.

[0010] Furthermore, the inner walls of several of the extension tubes are rotatably connected to bidirectional threaded rods, and the outer walls of the bidirectional threaded rods are slidably connected to limit blocks.

[0011] Through the above technical solution, multiple limiting blocks are connected to the outer wall of the bidirectional threaded rod, and the limiting blocks can be moved conveniently by rotating the bidirectional threaded rod.

[0012] Furthermore, a fixing plate is fixedly connected to the outer wall of the extension rod, and a spring is fixedly connected to the outer wall of the hollow tube.

[0013] With the above technical solution, a spring is connected to the hollow tube. The extension rod can be pushed to move on the inner wall of the hollow tube by the fixed plate, while squeezing the spring and releasing the pressure to fix the embedded block in the middle of the device.

[0014] Furthermore, a connecting column is fixedly connected to the outer wall of the fixing plate, a connecting plate is rotatably connected to the outer wall of the connecting column, a positioning column is rotatably connected to the outer wall of the connecting plate, and the outer wall of the positioning column is fixedly connected to the outer wall of the limiting block.

[0015] The above technical solution uses connecting columns and positioning columns at both ends of the connecting plate, and the positioning columns are connected to the limiting blocks, which makes it easy to restrict the embedded parts in the middle of the device.

[0016] Furthermore, the inner wall of the limiting block is provided with a plurality of sliding grooves, and an extension plate is slidably connected to the inner wall of the plurality of sliding grooves, and a soft positioning plate is fixedly connected to the outer wall of the fixing plate.

[0017] The above technical solution uses several grooves inside the limiting block and an extension plate that slides on the inner wall of the groove to prevent cement from overflowing due to excessive placement of embedded parts.

[0018] Furthermore, the bottom output shaft of the motor is fixedly connected to a connecting column two via a coupling, and a number of protrusions are fixedly connected to the outer wall of the connecting column two.

[0019] By fixing multiple protrusions on the connecting column 2 using the above technical solution, the connecting column 2 can be rotated by a motor, and the rotation of the protrusions will shake the steel bars and stir the air out of the cement.

[0020] Furthermore, the outer wall of the connecting block is provided with several positioning holes, and several locking blocks are rotatably connected to the outer wall of the connecting block.

[0021] The above technical solution allows for the creation of multiple positioning holes on the connecting block, which facilitates the rotation of the locking block to prevent the motor from detaching from the device during operation.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model incorporates an extension rod, allowing multiple limiting blocks to move via a bidirectional threaded rod. During the movement of the limiting blocks, the connecting plate rotates along the connecting column and positioning column, fixing multiple reinforcing bars in the middle. Simultaneously, the extension plate slides along the groove to increase the fixing area, and the extension rod connected to the outer wall of the fixing plate slides along the inner wall of the hollow tube. At the same time, the fixing plate compresses the spring, causing the spring to release pressure and fix the reinforcing bars. This achieves the goal of controlling the range between the fixing plates by moving the extension rod within the hollow tube, preventing situations where the number of embedded parts required for different construction requirements makes it difficult to adjust the connection dimensions.

[0024] 2. This utility model incorporates a protruding block, into which the connecting column two connected to the bottom of the motor is inserted. Multiple positioning holes on the inner wall of the connecting block pass through and are secured by multiple locking blocks connected to the outer wall of the fixed frame. The motor can then be started, causing the connecting column two to rotate. Simultaneously, the multiple protruding blocks fixed to the outer wall of the connecting column two strike multiple reinforcing bars. This achieves the goal of continuously squeezing out air from the protruding blocks by rotating the connecting column two with the motor, preventing the problem of air easily merging in during the fixing process and resulting in poor fixing effect.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

At the same time, the multiple protrusions 307 fixed on the outer wall of the connecting post 306 knock on the multiple steel bars, and at the same time, the air inside the cement is discharged to facilitate solidification.
