Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and in particular relates to a connection structure of steel structure frame beams. Background Art

[0002] Steel structure buildings are buildings that use construction steel to form a load-bearing structure. They are usually composed of beams, columns, trusses and other components made of steel and steel plates. Due to their simple construction, steel structure buildings are widely used in large factories, venues, super high-rise buildings and other fields.

[0003] At present, in steel structure buildings, columns are a common load-bearing component, while frame beams are used to connect columns and bear lateral loads. At present, most frame beams and columns are welded to the columns on site by welding the connection structure, and the crossbeams and columns are connected by multiple bolts and connecting plates. However, since the quality of welding depends on the skills of the construction workers, on-site welding may cause welding defects, welding deformation, welding joint fatigue and other problems, affecting the efficiency of construction; in addition, in the process of using external connection structure, the frame beam and the weight above are all pressed on the connection structure welded outside the column. When there is a problem with the welding, the connection of the frame beam is relatively fragile and prone to breakage and collapse. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing columns and beams need to be welded on site before being connected, which cannot guarantee the quality and will affect the construction efficiency. In addition, the beams are connected by a welded connection structure, which cannot guarantee the strength between the connection structure and the columns and is prone to breakage and collapse.

[0006] As an improvement, the width of the opening on the column on one side of the installation cavity is the same as the width of the widest part of the frame beam body, and the height of the opening on the column is the same as the height of the frame beam body.

[0007] As an improvement, a buffer pad is provided between the limiting plate and the frame beam body, and the buffer pad is a rubber pad.

[0008] As an improvement, the filling frame is a frame structure, and one side of the filling frame is against the side wall of the installation cavity, and the other side matches the side shape of the frame beam body. A mounting opening is provided above the filling frame, and the diameter of the mounting opening is greater than the width of the second bolt.

[0009] As an improvement, the reinforcement plate matches the outer shape of the column, and a block matching the shape of the installation cavity is provided at the installation cavity of the reinforcement plate, and the side of the reinforcement plate abutting against the frame beam body matches the shape of the side surface of the frame beam body.

[0010] As an improvement, a plurality of the first bolts are inserted from one end of the reinforcing plate, and pass through the filling frame and the frame beam body in the middle and come out from the reinforcing plate on the other side. The other end of the first bolt is threadedly connected with a first nut.

[0013] As an improvement, a plurality of the third bolts are inserted from one end of the reinforcing plate, and pass through the reinforcing plate and the frame beam body in the middle and come out from the reinforcing plate on the other side. The other end of the third bolt is threadedly connected to a third nut.

[0014] The advantages of the utility model compared with the prior art are:

[0015] The steel structure frame beam is prefabricated by welding a limit plate and a reinforcement column inside one side of the column to form an installation cavity. During the connection and installation of the frame beam, the filling frame, the reinforcement plate and the strengthening plate are combined and fixed by the cooperation of bolts and nuts. The overall installation is relatively fast and stable. The bolt assembly method can effectively avoid the problems of low work efficiency and fragile connection of the frame beam due to welding.
