Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to a connection structure between a steel structure column and a steel structure beam. Background Art

[0002] Steel structure buildings are a type of building that has developed rapidly in recent years. Compared with traditional reinforced concrete buildings, the components of steel structure buildings can be manufactured in factories and installed on site, which helps to greatly reduce the construction period. In addition, the steel can be reused, resulting in relatively less construction waste.

[0003] In the prior art, steel structure buildings are usually assembled and connected by welding or direct bolt connection;

[0004] Welding construction needs to be carried out on site, and its construction quality is highly dependent on the operator's operating level. High-altitude welding is inevitable during welding, which not only increases the risk, but also requires cutting of the steel for demolition, which affects the size and mechanical properties of the steel.

[0005] Although the bolt connection method is convenient, most of the steel structure beams and steel structure columns are directly fixed and supported by bolts, which has poor stability. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a connection structure between a steel structure column and a steel structure beam, so as to solve the technical problems mentioned in the above background technology.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A connection structure between a steel structure column and a steel structure beam, comprising a steel column, a support member and a steel beam;

[0009] The steel column is an I-steel, and the two side walls of the steel column are provided with a concave layer. The wall of the concave layer is provided with a plurality of column screw holes for installing fixing bolts, and the support member is inserted into the inner part of the concave layer;

[0010] The support member includes a connecting block, and fixing members are provided on both sides of the connecting block. The fixing members are arranged in a U-shaped shape, and support screw holes are provided on both side walls of the fixing members.

[0011] The steel beam is an I-beam, and a mounting plate is provided at one end of the steel beam and on both sides of the waist plate. The mounting plate is provided with beam screw holes. The side of the support away from the steel column is inserted between the two side plates of the steel beam, and the waist plate of the steel beam is inserted between the two fixing parts.

[0012] Furthermore, the support screw holes on both sides of the fixing member correspond to the column screw holes and the beam screw holes respectively.

[0013] Furthermore, the distance between the two fixing members is equal to the thickness of the waist plate of the steel column and the waist plate of the steel beam.

[0014] Furthermore, the height of the connecting block is equal to the height of the concave layer.

[0015] Furthermore, reinforcements are provided on both sides of the steel column and at the edges of the inner concave layer, and a column waist plate extends inside the inner concave layer.

[0016] Furthermore, the reinforcement includes a right-angle support plate, the inner corners of the right-angle support plate are provided with triangular reinforcement ribs, and the two side walls of the right-angle support plate are respectively fitted with the side plates of the steel beam and the steel column.

[0017] In summary, the present invention has at least one of the following beneficial technical effects:

[0018] 1. This connection structure of steel columns and steel beams fixes the steel columns and steel beams through support members. Compared with the welding connection method, the combination of bolts and support members can effectively facilitate the disassembly of the steel structure, reduce the duration of high-altitude operations, and effectively improve the safety of the operation. Compared with the direct bolt connection method, the support members can also provide good support for the connection between the steel beams and steel columns, thereby providing good stability to the steel structure.

[0019] 2. This connection structure between a steel structure column and a steel structure beam uses bolts to install the right-angle support plate at the corner where the steel beam and the steel column are connected, and the strength of the right-angle support plate is increased by setting triangular reinforcement ribs to further improve the stability of the steel structure connection.

[0029] Reference Figure 1 - Figure 5 The utility model discloses a connection structure between a steel column and a steel beam, comprising a steel column 1, a support member 2 and a steel beam 3;

[0030] The steel column 1 is an I-steel, and the two side walls of the steel column 1 are provided with a concave layer 11. The wall of the concave layer 11 is provided with a plurality of column screw holes 12 for installing fixing bolts, and the support member 2 is inserted into the inner part of the concave layer 11;

[0032] The steel beam 3 is an I-beam, and a mounting plate 31 is provided at one end of the steel beam 3 and on both sides of the waist plate. The mounting plate 31 is provided with a beam screw hole 32. The side of the support member 2 away from the steel column 1 is inserted between the two side plates of the steel beam 3, and the waist plate of the steel beam 3 is inserted between the two fixing members 22.

[0033] After the bolts 12 are inserted into the holes 12 and 13 of the support 2, the support 2 is fixed to the steel column 1. Then, one end of the steel beam 3 is aligned with the support 2, and the waist plate of the steel beam 3 is inserted between the two fixing parts 22. At this time, the fixing part 22 is in contact with the mounting plate 31. Then, the beam screw holes 32 and the support screw holes 23 are connected by bolts and the bolts are tightened. At this time, the fixed connection between the steel beam 3 and the steel column 1 is completed. Compared with the welding connection method, the combination of bolts and support members 2 can effectively make the steel structure easy to disassemble, reduce the duration of high-altitude operations, and effectively improve the safety of the operation. Compared with the direct bolt connection method, the support member 2 can also provide good support for the connection between the steel beam 3 and the steel column 1, thereby providing good stability for the steel structure.

[0036] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the distance between the two fixing members 22 is equal to the thickness of the waist plate of the steel column 1 and the waist plate of the steel beam 3.

[0037] In this embodiment, since the distance between the two fixing members 22 is equal to the width of the waist plate of the steel column 1 and the waist plate of the steel beam 3, when the support member 2 is connected to the steel column 1 and the steel beam 3, the waist plate part can be inserted between the two fixing members 22 to achieve the purpose of improving the stability of the connection.

[0038] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the height of the connecting block 21 is equal to the height of the concave layer 11 .

[0039] In this embodiment, the height of the connecting block 21 is equal to the height of the inner concave layer 11. Therefore, during installation, the top and bottom ends of the connecting block 21 can contact the top and bottom surfaces of the inner concave layer 11 to further improve the stability of the steel structure.

[0041] In this embodiment, the reinforcement 13 is provided to improve the stability of the connection between the steel column 1 and the steel beam 3, and the column waist plate 14 is equal in thickness to the waist plate of the steel column 1. When the support member 2 is inserted into the inner concave layer 11, it cooperates with the gap between the two fixing members 22 to facilitate the installation of the support member 2.

[0042] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the reinforcement 13 includes a right-angle support plate 131, and a triangular reinforcement rib 132 is provided at the inner corner of the right-angle support plate 131. The two side walls of the right-angle support plate 131 are respectively fitted with the side plates of the steel beam 3 and the steel column 1.
