Description

Technical Field

[0001] The present invention relates to the technical field of building steel structure connection components, and in particular to a prestressed self-stabilizing steel structure component. Background Art

[0002] An assembled building structure refers to a building in which the main parts are made of prefabricated components and assembled through reliable connection methods. This building method transfers a large amount of on-site work in the traditional building method to the factory. The building components and fittings are processed and manufactured in the factory and then transported to the building construction site for assembly. The steel structure has high strength, good plasticity and ductility, which enables the steel structure connectors to bear large loads and deformations in the assembled building, ensuring the safety and stability of the building. At present, in order to improve the structural strength of the steel structure, prestressed steel bars are generally added to the steel structure. Although the bearing capacity of the structure is improved, most of them are still fixed on the steel structure beam through bolt structures.

[0003] For example, a Chinese patent with the publication number CN218292286U discloses a connection component for an assembled steel structure, including a first steel structure. A second steel structure is arranged directly below the first steel structure. Connection frames are sleeved on the left and right sides of the outer surfaces of the first steel structure and the second steel structure. Reinforcing angle steels are arranged on the front and rear sides of the inner surface of the connection frame, and reinforcing bolts are passed through the reinforcing angle steels.

[0004] Although the above-mentioned disclosed patent realizes the reinforcement between the first steel structure, the second steel structure and the connection frame, however, its connection frame still relies on traditional connection structures such as reinforcing bolts to be fixed on the first steel structure beam and the second steel structure beam for stability. This approach inevitably requires drilling holes in the first steel structure beam and the second steel structure beam, which is a physical damage to the original structure. Drilling holes will weaken the stress-bearing part at the connection of the steel structure beam, resulting in stress concentration, and further increasing the risk of fatigue damage during long-term use of the structure, weakening its original mechanical properties and integrity. Moreover, the bolt installation is also relatively complex, with a large construction difficulty and workload. Summary of the Invention

[0005] The purpose of the present invention is to provide a prestressed self-stabilizing steel structure component to solve the problems mentioned in the above background art.

A first torsion block is fixedly connected to the top of the first lead screw. One side of the first sliding plate is fixedly connected to one side of the first positioning rubber block. A limiting groove is provided inside the pressing block. A limiting block is slidably connected inside the limiting groove, and the limiting block is fixedly connected to the first sliding plate.

[0009] Further, the second power component includes a driving shaft, which is rotatably connected to one side of the first connecting member. A second torsion block is fixedly connected to the top of the driving shaft. A transmission gear is fixedly connected to the middle of the driving shaft. Transmission racks are meshed and connected to both sides of the transmission gear. One side of the transmission rack is fixedly connected to one side of the guiding block. A sliding block is fixedly connected to the side of the transmission rack away from the guiding block. A limiting frame is fixedly connected inside the first connecting member, and the sliding block is slidably connected to the limiting frame.

[0010] Furthermore, the fixing component includes a second lead screw, which is rotatably connected to the side of the first connecting piece away from the drive shaft. A second sliding plate is threadedly connected to the outer surface of the second lead screw. A second connecting block is fixedly connected to the bottom end of the second sliding plate. A second positioning rubber block is fixedly connected to the bottom end of the second connecting block. A second connecting groove is formed on one side of the connecting support plate.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] First, in the present invention, grooves are formed on both sides of the first connecting piece and the second connecting piece. A transmission plate is installed in each groove. The transmission plate is movably arranged in the groove through a tension spring. The transmission plate is connected to a pressing block. By using the pressing blocks on both sides to fit on the I-shaped steel structure beam, the first connecting piece and the second connecting piece can be installed on the steel structure beam. Then, the first power component drives the first positioning rubber block to extend out of the receiving groove and move towards the steel structure beam. Under the action of the first positioning rubber blocks on both sides, the installation positions of the first connecting piece and the second connecting piece are further stabilized, enabling the self-stable installation of the first connecting piece and the second connecting piece. There is no need to open holes at the joints of the steel structure beam, thus avoiding problems such as structural physical damage and stress concentration caused by hole opening, reducing the weak links in the structure caused by hole opening, extending the service life of the structure, maintaining the original mechanical properties and integrity of the steel structure beam, and reducing the risk of fatigue damage during long-term use.

[0014] Second, in the present invention, a second power component is installed on the first connecting piece. By using the second power component to drive the guide block to move, the guide block slides in the guide groove of the second connecting piece. The first connecting block connected to the guide block is inserted into the first connecting groove of the guide groove, enabling the adjacent first connecting piece and the second connecting piece to be connected and fixed, making the connection of the two steel structure beams stable, thereby ensuring the stability of the overall structure of the steel structure assembly. There is no need to rely on bolts for fixation, which is more convenient than traditional methods such as bolt connection, reducing the on-site operation volume and construction difficulty, reducing the installation time and labor cost, and improving the connection efficiency and reliability.

[0015] Thirdly, in the present invention, by installing an articulated support plate on one side of the second connecting member, the articulated support plate supports the steel structure beam to prevent deformation at the center of the main body. Prestressed steel bars are installed inside the articulated support plate. By applying tensile force in advance, a relatively high pressure is generated inside the steel bars. When the steel structure is subjected to external forces, the prestressed steel bars can better resist the external forces, thereby improving the load-bearing capacity of the entire structure. The articulated support plate can be connected to the first connecting member on the adjacent steel structure beam through a fixing component. In this process, the connection stability between the first connecting member and the second connecting member and the steel structure beam can also be improved, further enhancing the integrity and stability of the structure, and enhancing the load-bearing capacity of the steel structure components, providing a strong guarantee for project safety.

[0032] The working principle of the present invention is as follows: The first connecting member 2 and the second connecting member 3 are respectively sleeved on both sides of the steel structure beam 1. The arc-shaped edge of the lower pressing block 53 is in contact with the steel structure beam 1 to bear force. The lower pressing block 53 pushes the transmission plate 51. The transmission plate 51 rotates through the transmission shaft 52 and pushes the tension spring 511 at the bottom to deform. Under the action of the tension spring 511, the lower pressing plate fits on the steel structure beam 1, so that the first connecting member 2 and the second connecting member 3 can be installed on the steel structure beam 1. Then, rotate the first torsion block 563. The first torsion block 563 drives the first lead screw 561 to rotate, driving the first sliding plate 562 on the outer surface of the first lead screw 561 to move. The first sliding plate 562 drives the first positioning rubber block 55 to move, so that the first positioning rubber block 55 fits on the steel structure beam 1, further stabilizing the installation positions of the first connecting member 2 and the second connecting member 3, and enabling the self-stable installation of the first connecting member 2 and the second connecting member 3. Then, align the guiding block 7 with the guiding groove 6. Then, rotate the second torsion block 82. The second torsion block 82 drives the driving shaft 81 to rotate. The driving shaft 81 drives the transmission gear 83 to rotate. The transmission gear 83 drives the two transmission racks 84 to move relatively. The transmission rack 84 drives the guiding block 7 to move. The guiding block 7 drives the first connecting block 71 to move. The first connecting block 71 is inserted into the first connecting groove 61 of the guiding groove 6, so that the first connecting member 2 and the second connecting member 3 are kept fixed. During the movement of the transmission rack 84, the sliding block 85 slides on the limiting frame 86 to limit the sliding position of the transmission rack 84. When the driving shaft 81 rotates, the driving shaft 81 drives the first transmission sprocket 91 to rotate. The first transmission sprocket 91 drives the second transmission sprocket 93 to rotate through the transmission chain 92. The second transmission sprocket 93 drives the second lead screw 111 to rotate, driving the second sliding plate 112 to move. The second sliding plate 112 drives the second connecting block 113 to move. The second connecting block 113 is inserted into the second connecting groove 114 of the connecting support plate 10 to stabilize the position of the connecting support plate 10. The connecting support plate 10 supports the steel structure beam to prevent deformation at the center of the main body. The second positioning rubber block 1131 is installed at the end of the second connecting block 113. The second positioning rubber block 1131 passes through the second connecting groove 114 and passes through the through hole 115 of the first connecting member 2 to contact the steel structure beam 1, further stabilizing the position of the first connecting member 2, thereby stabilizing the position of the second connecting member 3, improving the bearing capacity of the steel structure component, providing a strong guarantee for project safety. Therefore, there is no need to open holes at the joints of the steel structure beam 1, thus avoiding the problems of structural physical damage and stress concentration caused by hole opening. Since the original mechanical properties and integrity of the steel structure beam 1 are maintained, the risk of fatigue damage during long-term use is reduced. There is no need to use bolts for fixation, which is more convenient than traditional methods such as bolt connection, reducing the on-site operation volume and construction difficulty, reducing the installation time and labor cost, and improving the connection efficiency and reliability.
