According to the technical scheme, the device comprises a stand column and cross beams horizontally installed on the two sides of the stand column, and further comprises a U-shaped clamping plate movably inserted into the stand column and the cross beams so that the stand column and the cross beams can be rapidly connected; the inclined supporting rods are movably installed at the connecting positions of the stand columns and the cross beams to disperse force at the connecting positions of the stand columns and the cross beams, and first U-shaped clamping frames are installed at the close ends of each pair of horizontally-opposite inclined supporting rods. The U-shaped clamping plate, the inclined supporting rod, the first U-shaped clamping frame, the second U-shaped clamping frame and other structures are matched, so that the stand columns are mostly connected with the cross beams on the two sides of the stand columns in a mortise and tenon joint mode, and load is transmitted through large-area contact of joint faces in the mortise and tenon joint mode. The load distribution is relatively uniform and is not concentrated at a specific point like bolt connection. Therefore, the stress of the whole structure is more uniform, and the risk caused by stress concentration is reduced.

[0002] Steel structure workshop is a type of workshop structure that uses steel as the main building material and is widely used in industries, commerce, warehousing and other fields. Steel structure workshop has the advantages of light weight, high strength, fast construction speed and good earthquake resistance, so it is becoming more and more popular in modern buildings. Its structure consists of columns and beams. The traditional connection between beams and columns is usually bolted, and bolted connection will cause stress concentration at the connection part due to the preload applied by the bolts, especially at the edges and corners of the bolt holes. This stress concentration makes the stress level in these areas higher, which is easy to exceed the fatigue limit of the material, thereby causing the formation of fatigue cracks. Utility Model Content

[0003] The purpose of the utility model is to solve the problem that the traditional connection between beams and columns is usually bolted, and the pre-tightening force applied by the bolts will lead to stress concentration at the connection parts, especially at the edges and corners of the bolt holes. This stress concentration makes the stress level in these areas higher, which is easy to exceed the fatigue limit of the material, thereby causing the formation of fatigue cracks. A large-span steel structure factory building beam-column structure is proposed.

[0004] The technical solution of the utility model is as follows: a large-span steel structure factory building beam-column structure, comprising columns and beams horizontally installed on both sides of the columns, and also comprising: a U-shaped clamping plate, which is movably inserted into the columns and the beams so that the columns and the beams can be quickly connected; an inclined support rod, which is movably installed at the connection between the columns and the beams to disperse the force at the connection between the columns and the beams, and each pair of horizontally adjacent ends of the inclined support rods is installed with a first U-shaped clamping frame, and each pair of vertically adjacent ends of the inclined support rods is installed with a second U-shaped clamping frame.

[0005] Optionally, one end of the beam close to the column is fixedly connected with a pair of U-shaped sockets, the top of the U-shaped sockets is provided with installation slots for U-shaped card boards to be inserted into, and the side surfaces of the columns close to the beam are provided with multiple rectangular sockets for the U-shaped sockets to be inserted into.

[0006] Optionally, the columns and beams are provided with elliptical sockets for installing inclined support rods, both ends of the inclined support rods are fixedly connected with circular support plates that resist the columns and beams, the circular support plates are fixedly connected with insertion rods, and the ends of the insertion rods away from the circular support plates are fixedly connected with circular blocking blocks that pass through the elliptical sockets.

[0007] Optionally, both ends of the first U-shaped bracket and the second U-shaped bracket are provided with U-shaped slots for clamping the insertion rod, the inner wall of the column and the circular block are jointly clamped at the end of the first U-shaped bracket, and the inner wall of the beam and the circular block are jointly clamped at the end of the second U-shaped bracket.

[0008] Optionally, a mounting screw is provided on the crossbeam in the middle of the second U-shaped bracket, and both ends of the mounting screw are spirally connected with nuts that resist the second U-shaped bracket.

[0009] Optionally, the U-shaped clamping plate firmly clamps the U-shaped insertion hole at the end of the beam by gravity, and the first U-shaped clamping frame firmly clamps the connected ends of the horizontal relatively inclined support rods by gravity.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] The utility model utilizes the cooperation of structures such as the U-shaped card plate, the inclined support rod, the first U-shaped card frame and the second U-shaped card frame, so that the connection between the column and the beams on both sides thereof is mostly mortise and tenon connection, and the mortise and tenon connection usually transmits the load through the large area contact of the joint surface. This load distribution is more uniform and will not be concentrated at a specific point like a bolt connection. Therefore, the overall structure is more evenly stressed, reducing the risk of stress concentration. BRIEF DESCRIPTION OF THE DRAWINGS
