Embodiment Construction

[0021] The present invention is described in detail below in conjunction with accompanying drawing:

[0022] Such as figure 1 , figure 2 As shown, a steel structural beam includes a sleeve 10 and an inner sleeve 20 . The sleeve 10 has a sleeve wall 11 which encloses a sleeve lumen 12 . The casing wall 11 is provided with a first through groove 13 , the first through groove 13 runs through the casing wall 11 and communicates with the casing lumen 12 .

[0023] The inner sleeve 20 has an inner sleeve wall 21 which encloses an inner sleeve cavity 22 . The inner casing wall 21 is provided with a second through groove 23 , and the second through groove 23 extends along the length direction of the inner casing wall 21 .

[0024] The inner sleeve 20 is disposed in the sleeve lumen 12 , and the inner sleeve 20 extends for a selected length along the length direction of the sleeve 10 , and its specific length can be determined according to actual use requirements. The inner sleev...

Abstract

The invention discloses a steel structure beam. The steel structure beam is characterized in that the steel structure beam comprises a sleeve and an inner sleeve. The sleeve is provided with a sleeve wall. A sleeve cavity is defined by the sleeve wall. A first through groove is formed in the sleeve wall. The first through groove penetrates through the sleeve wall and communicates with the sleeve cavity. The inner sleeve is arranged in the sleeve cavity. The inner sleeve is connected with the sleeve wall. The inner sleeve extends in the length direction of the sleeve. According to the steel structure beam, the first through groove is formed in the sleeve wall so that a welding device can stretch into the sleeve cavity conveniently to weld the sleeve wall and other structures together; and in addition, the welding area is large, weld joints are long, and the effect that welded connection is firm is guaranteed.

Description

technical field [0001] The invention specifically relates to a steel structure beam. Background technique [0002] Beams are one of the main components of steel structure houses. In the prior art, the length of the beam is determined according to the distance between two columns. Both ends of the beam are supported by columns, so the length of the beam is adapted to the spacing of the columns. The reason why it is set up like this, the first is because the beams of more than two sections cannot be well connected, the connection method in the prior art either makes the appearance of the beam messy, or the connection is not firm, resulting in failure to meet the use requirements. For the product connection of steel structure, welding is the most important connection method except for fastener connection. If the use of fasteners will destroy the appearance of the beam, it still needs to be achieved by welding. However, the structural design of the beams in the prior art mak...
