Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, and in particular to a steel structure reinforcement device. Background Technology

[0002] Steel structures are structures made primarily of steel, consisting of steel beams, columns, trusses, and other components made of shaped steel and steel plates. These components or parts are connected by welds, bolts, or rivets, and are widely used in construction, bridges, large equipment, and other fields.

[0003] In the existing technology, during the use of steel structures, it is necessary to reinforce the joints of the steel structures in order to ensure their stability. However, the reinforcement structure is not easy to adjust flexibly according to the usage of the steel structure, which will affect the reinforcement effect. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the use of steel structures, in order to ensure the stability of the steel structure, it is necessary to reinforce the connection of the steel structure. However, the reinforcement structure is not easy to be flexibly adjusted according to the use of the steel structure, which will affect the reinforcement effect. Therefore, a steel structure reinforcement device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A steel structure reinforcement device includes two connecting plates. Connecting seats are fixedly connected to the side walls of the two connecting plates. Movable plates are hinged inside the connecting seats. Sleeves are slidably fitted onto the side walls of the two movable plates. Slider blocks are fixedly connected to one end of each movable plate inside the sleeve. A fixed plate is fixedly connected to the inner wall of the sleeve. A bidirectional lead screw is rotatably connected inside the fixed plate. Through grooves are formed on the inner walls of the movable plates and sliders. Threaded rings are fixedly connected inside the two sliders. The interiors of the two threaded rings are threadedly connected to the bidirectional lead screw. A motor is fixedly connected to the bottom of the sleeve.

[0007] Preferably, the output shaft end of the motor extends into the interior of the housing and is fixedly connected to a first bevel gear, and a second bevel gear is fixedly sleeved on the rod wall of the bidirectional lead screw, with the first bevel gear and the second bevel gear meshing with each other.

[0008] Preferably, the slider has an opening on its side wall and the slider has a concave cross-section.

[0009] Preferably, the bottom of the connecting plate has a notch, and the connecting plate is fixedly connected to the inner wall of the notch with reinforcing fins.

[0010] Preferably, the interior of each of the two connecting plates has multiple mounting holes.

[0011] Preferably, the two connecting plates have grooves on opposite sides, and the inner walls of the grooves are curved.

[0012] Compared with the prior art, this utility model provides a steel structure reinforcement device with the following advantages:

[0013] 1. The steel structure reinforcement device can be reinforced by installing connecting plates on both sides onto the steel structure. The connecting seat, movable plate and sleeve can be adjusted to facilitate reinforcement of steel structures with different structural distances.

[0014] 2. The steel structure reinforcement device can drive the first bevel gear to rotate and drive the second bevel gear to rotate through the rotation of the motor. The rotation of the second bevel gear can drive the bidirectional screw to rotate along the inner wall of the fixed plate, so that the threaded ring moves along the wall of the threaded rod. This can drive the movable plate to move, so that the movable plate can extend out along the inside of the sleeve, which is convenient for adjusting the distance between the two connecting plates.

[0015] 3. The steel structure reinforcement device can improve the strength of the connecting plate by strengthening the fins, while the mounting holes can facilitate the stability of the connection between the connecting plate and the steel structure. The mounting plate has an arc surface on the inner wall of the groove, which can improve the stability of the connection with the arc-shaped steel structure and improve the compatibility of the connection.
