Description

Technical Field

[0001] This utility model relates to the field of steel structure beams and columns, specifically a steel structure beam and column joint reinforcement structure. Background Technology

[0002] Steel structures are widely used in modern architecture due to their high strength, lightweight, and fast construction speed. As the core force-transmitting component of a steel structure, the beam-column joint directly affects the stability and safety of the overall structure.

[0003] According to the existing technology, among the connection methods of steel structure beam-column joints, rigid connection is the most common and has high rotational stiffness. Welding is mainly used for connection. In real life, the failure of steel structures is basically brittle failure, that is, the failure of beam-column joints or column base welds. Welding often leads to changes in the microstructure and properties of welded joints. If not properly controlled, it will seriously affect the quality of structural components. Welds and heat-affected zones can produce a variety of defects due to improper processes or operations, which will reduce the load-bearing capacity of the structure.

[0004] Therefore, those skilled in the art provide a steel beam-column joint reinforcement structure to solve the problems mentioned in the background art. Utility Model Content

[0007] 2. Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A steel structure beam-column joint reinforcement structure includes a vertical column and a horizontal beam. The horizontal beam is located on the side of the vertical column. A support plate is provided on one side of the vertical column. Threaded holes are opened on one side of the vertical column and inside the support plate, and bolts are threadedly connected to them. The support plate is fixedly connected to the vertical column by bolts and threads. Horizontal fixing plates are provided on both the upper and lower sides of the horizontal beam. A vertical fixing plate is fixedly connected to one end of the horizontal fixing plate. A reinforcing plate is provided on the side of the horizontal fixing plate away from the horizontal beam. Threaded holes are opened inside the reinforcing plate and inside the horizontal fixing plate, and bolts are threadedly connected to them. The reinforcing plate is fixedly connected to the horizontal fixing plate by bolts through threaded holes. A diagonal brace is provided at the bottom of the horizontal beam. A first side plate is provided on both sides of the horizontal beam. A second side plate is fixedly connected to one end of the first side plate.

[0010] The above technical solution allows the reinforcing mechanism to be fixed with bolts during use, and the vertical column and horizontal beam can be fixed in multiple directions, increasing the connection between the vertical column and the horizontal beam and further enhancing the tightness of the connection. This solves the problem that rigid welding connections can lead to changes in the structure and properties of the weld joint, which can seriously affect the quality of the structural components if not properly controlled. Furthermore, improper processes or operations can cause various defects in the weld and heat-affected zone, reducing the load-bearing capacity of the structure.

[0011] Furthermore, four second positioning pins are fixedly connected to one side of the vertical column, and the support plate has through holes that are adapted to the second positioning pins.

[0012] Through the above technical solution, the second positioning pin can position and support the support plate, facilitating the fixing of the support plate.

[0013] Furthermore, the horizontal fixing plate and the vertical fixing plate are an integrated structure.

[0014] The above technical solution uses bolts to fix the horizontal and vertical fixing plates to the support plate, which not only ensures the connection of the crossbeam, but also facilitates the future maintenance and disassembly of the crossbeam.

[0015] Furthermore, a first positioning pin is fixedly connected to the top of the crossbeam, and through holes adapted to the first positioning pin are opened inside one of the horizontal fixing plates and one of the reinforcing plates.

[0016] Through the above technical solution, the first positioning pin can limit and support the reinforcing plate, and the reinforcing plate can enhance the strength of the horizontal fixing plate and increase the support of the horizontal fixing plate for the crossbeam.

[0017] Furthermore, a first positioning plate and a second positioning plate are fixedly connected to both ends of the diagonal brace plate, respectively. Threaded holes are opened inside the first positioning plate, the second positioning plate, the reinforcing plate, and the support plate, and bolts are threadedly connected to them. The first positioning plate is fixedly connected to the reinforcing plate by threads and bolts, and the second positioning plate is fixedly connected to the support plate by threads and bolts.

[0018] Through the above technical solution, the diagonal bracing plate can form a triangle between the vertical column and the horizontal beam, thereby providing support for the horizontal beam at another angle and increasing the connection between the horizontal beam and the vertical column.

[0019] Furthermore, a third positioning pin and a fourth positioning pin are fixedly connected to the side of the support plate, and a through hole adapted to the third positioning pin is opened inside the second positioning plate, and a through hole adapted to the fourth positioning pin is opened inside one of the vertical fixing plates.

[0020] Through the above technical solution, the third positioning pin can provide limiting support for the second positioning plate, thereby determining the position of the diagonal brace plate.

[0021] Furthermore, through holes are provided inside the first side plate and the crossbeam. A reinforcing bolt is provided in the through hole of the crossbeam. A reinforcing nut is threaded to the outside of the reinforcing bolt. Threaded holes are provided inside the second side plate and the support plate. The second side plate is fixedly connected to the support plate by threads and bolts.

[0022] Through the above technical solution, the reinforcing bolts and reinforcing nuts can fix the second side plate to the crossbeam, and during fixing, the two second side plates are connected synchronously, thereby providing support to the crossbeam in another direction.

[0023] Furthermore, positioning posts are fixedly connected to both sides of the crossbeam, and through holes adapted to the positioning posts are opened inside the first side plate.

[0024] Through the above technical solution, the positioning column can determine the position of the second side plate, avoiding deviation in the position of the second side plate when fixing it, which would affect the support effect and installation efficiency.

It also allows for pre-alignment of the threaded holes between the reinforcement structures, preventing loosening at the connection points.

[0042] The working principle of the above embodiment is as follows: In use, first, the support plate 3 is fixed to the vertical column 1. During fixing, the support plate 3 is placed on the side of the vertical column 1, so that the second positioning pin 8 enters the internal through hole of the support plate 3, thereby limiting the position of the support plate 3 and supporting the support plate 3. Then, the support plate 3 and the vertical column 1 can be fixedly connected by bolts. After the support plate 3 is fixed, the diagonal brace 9 is fixed. During fixing, the third positioning pin 12 enters the interior of the second positioning plate 11, thereby limiting and supporting the second positioning plate 11. Then, the second positioning plate 11 and the support plate 3 are fixed by threads. Then, one of the vertical fixing plates 4 and the horizontal fixing plate 5 are placed, so that the third positioning pin 12 enters the interior of one of the vertical fixing plates 4, thereby limiting and supporting the vertical fixing plate 4. Then, one of the vertical fixing plates 4 and the support plate 3 are fixed by bolts. Then, the reinforcing plate 6 and the horizontal fixing plate 5 can be connected by bolts. Then, the crossbeam 2 is placed, and the top of one of the horizontal fixing plates 5... The beam 2 is initially fixed by bolting one of the horizontal fixing plates 5 to the crossbeam 2 and the first positioning plate 10 to the crossbeam 2. After fixing, the other vertical fixing plate 4 and the other horizontal fixing plate 5 are placed on top of the crossbeam 2. During placement, the first positioning pin 7 limits and fixes the other horizontal fixing plate 5. Then, the horizontal fixing plate 5 is fixed to the crossbeam 2 and the other vertical fixing plate 4 is fixed to the support plate 3. This completes the initial fixing of the crossbeam 2. Then, the two first side plates 14 are placed on both sides of the crossbeam 2 and the second side plates 15 are limited by the positioning pin 18. After the limitation is completed, the first side plates 14 are fixed to the support plate 3 by bolting. Then, the reinforcing bolts 16 are passed through the two second side plates 15 and the crossbeam 2. Then, the reinforcing bolts 16 are limited by the reinforcing nuts 17. This fixes the second side plates 15 to the crossbeam 2. During fixing, the two second side plates 15 are connected synchronously. Then, the installation of the structure is completed, thus completing the connection between the crossbeam 2 and the vertical column 1.
