[0003] The prefabricated steel structure buildings have the inherent advantages of prefabricated buildings. The fundamental factor for the development of prefabricated buildings is the cost. The rectangular beam has good structural stability and can be used as preferred structural material for steel structure buildings. The rectangular beams and columns with embedded walls will give the whole building an improved wind and earthquake resistance while reducing the supporting components and the construction cost.

A part of the inner lining bushing is embedded in the first section of the rectangular column, and the other part of the inner lining bushing is embedded in the second section of the rectangular column. The rectangular column and the inner lining bushing are then fixed by fasteners, thereby achieving internal connection of the nodes. But generally speaking, in order to facilitate the movement of the inner lining bushing in the rectangular column, a gap of about 1 mm needs to be reserved. However, due to the existence of the gap, the stability will be weakened after assembly.
[0005] In summary, how to solve the problem of poor stability of the reinforcement structure of the rectangular column and beam connecting node in prefabricated steel structure building has become a technical problem urgently needed to be solved by those skilled in the art.
[0006] The objective of this utility model is to provide a reinforcement structure of the rectangular column and beam connecting node in prefabricated steel structure building, so as to solve the problem of poor stability of the existing reinforcement structure of the rectangular column and the beam connection in prefabricated steel structure building.
[0007] In order to achieve the objective, the utility model provides a reinforcement structure of a rectangular column and beam connecting node in prefabricated steel structure building, which is applied to a rectangular column node.

The flexible end plate is provided with a first connecting bit connected with the first lining plate, a second connecting bit connected with the second lining plate, a third connecting bit connected with the third lining plate, and a fourth connecting bit connected with the fourth lining plate.
[0008] Preferably, the first lining plate, the second lining plate, the third lining plate, and the fourth lining plate are provided with threaded holes for connecting the rectangular column nodes.
[0009] Preferably, the first lining plate, the second lining plate, the third lining plate, and the fourth lining plate are provided with prefabricated nuts formed by hot melting or hot forging, and the prefabricated nuts are provided with threaded holes.
[0010] Preferably, the first connection bit, the second connection bit, the third connection bit, and the fourth connection bit are all flexible connection bits.
[0011] Preferably, the flexible connection bits are of flexible shrapnel structure.
[0012] Preferably, the node area of the rectangular column node is the area between a column and a column, between a beam and a beam, or the area between a column and a beam.
[0013] Preferably, the structure further comprises an enclosing plate disposed on the circumferential outer side of the node area of the rectangular column node, the enclosing plate being simultaneously connected to the first section of the rectangular column and the second section of the rectangular column, or the enclosing plate alone being connected to the second section of the rectangular column in a column node area.
[0014] Preferably, the enclosing plate is formed by splicing four rectangular plates in an end-to-end manner; the enclosing plate is first formed either by connecting the rectangular plate with the first section of rectangular column and the second section of rectangular column with fasteners, or by connecting the rectangular plate with the second section of rectangular column with fasteners and connecting any adjacent rectangular plates with welding, which connects the rectangular column and the corresponding rectangular plate to form a stable unity.
[0015] Preferably, at least one of the rectangular plate is provided with bracket disposed perpendicular to the rectangular plate.
[0016] Compared with the existing structures introduced in the background technology, the reinforcement structure of the rectangular column and beam connection node in prefabricated steel structure building is applied to the reinforcement structure of the rectangular column node, including rectangular lining structure enclosed by the first lining plate, the second lining plate, the third lining plate, and the fourth lining plate and flexible end plates located at both ends of the rectangular lining structure; there is a preset splicing gap between any adjacent two of the first lining plate, the second lining plate, the third lining plate, and the fourth lining plate; the flexible end plate is provided with a first connection bit connected to the first lining plate, a second connection bit connected to the second lining plate, a third connection bit connected to the third lining plate and a fourth connection bit connected with the fourth lining plate. In its application, the lining structure can be used for the connection of rectangular column nodes, such as the connection between the columns, or the connection between the beams. The front and rear end plates of the above lining structure being flexible type gives the entire lining structure a certain circumferential deformability. Therefore, the first lining plate, the second lining plate, the third lining plate, and the fourth lining plate of the lining structure can be fitted much closer to the inner walls of the column, which effectively reduces the fit clearance between the inner lining plate and the inner wall of the rectangular column, thereby greatly improving the stability of the inner lining plates and the inner walls of the rectangular column after connection.
