Problems solved by technology

[0002] Prefabricated buildings have the advantages of environmental protection and fast construction speed, and become one of the important directions of future building development. Prefabricated steel structures are one of the important components of prefabricated buildings. In the past, in prefabricated steel structures, beam-column joints mainly used Welding connection relies on the weld to transfer the force between beams and columns. This kind of joint has high requirements for welding quality, complex construction, large welding quality affected by human factors, large residual stress in the weld and around the weld, and strong seismic performance affected by the weld.

Embodiment 1

[0033] like Figure 1-7 As shown, an object of the present invention is to provide a beam-column tenon-mortise joint structure of a fabricated steel structure, which can include:

[0034]The connecting column 10 includes a vertical column body 11 arranged through the vertical column body 11, and four connecting grooves 12 are evenly arranged around the vertical column body 11; The clamping block 21 that penetrates into the vertical column body 11; the top side longitudinal beam 30, the bottom side of the top side longitudinal beam 30 is provided with a first connecting column bump 31 and a first cross beam bump 32, and the first connecting column bump 31 and The first connecting column clamping groove 33 on the top side of the vertical column body 11 is clamped and arranged, and the first beam protrusion 32 is clamped and arranged with the first beam clamping groove 34 on the top side of the beam 20, and extends through the connection groove 12; The side longitudinal beam 40 ...

Embodiment 2

[0037] In a preferred embodiment, the side of the clamping block 21 away from the vertical column body 11 is arranged in an arc-shaped structure; the top side longitudinal beam 30 and the bottom side longitudinal beam 40 are also symmetrically provided with a structural plate 50, and the structural plate 50 is vertically fixed On the inner side of the vertical column 11, a rectangular column 51 is arranged between the two structural plates 50, the rectangular column 51 is fixedly connected to the structural plate 50, and four sides of the rectangular column 51 are provided with guide grooves 52, and the inner side of the guide groove 52 is provided with a first Spring 53, a sliding block 54 is slidably connected to one side of the first spring 53; when the sliding block 54 moves to the side of the blocking block 21, the sliding block 54 moves along the inner side of the guide groove 52 until the sliding block 54 moves to the other side of the blocking block 21. On one side, the...

Embodiment 3

[0040] In another preferred embodiment, the bottom side of the rectangular column 51 of the top side rail 30 has a convex column 55 , the top side of the rectangular column 51 of the bottom side rail 40 has a groove 56 , and the convex column 55 is clamped in the groove 56 .

[0041] Wherein, the beam-column tenon-mortise joint structure of the assembled steel structure of the present application is clamped in the groove 56 by the convex column 55, so that the top side longitudinal beam 30 and the bottom side longitudinal beam 40 are connected to form a whole, so that the whole structure forms a whole.

Abstract

The invention provides a beam-column tenon-and-mortise joint structure and method for an assembly type steel structure, and the structure comprises a connecting column which comprises a vertical column body arranged in a penetrating manner, and four connecting grooves are uniformly formed in the periphery of the vertical column body; the cross beams are respectively clamped on the outer sides of the connecting grooves and are provided with clamping blocks extending and penetrating into the vertical column bodies; the bottom side of the top side longitudinal beam is provided with a first connecting column protruding block and a first cross beam protruding block, the first connecting column protruding block is connected with the first connecting column clamping groove in the top side of the vertical column body in a clamped mode, and the first cross beam protruding block is connected with the first cross beam clamping groove in the top side of the cross beam in a clamped mode and extends to penetrate into the connecting groove. Compared with welding construction, the beam column tenon-and-mortise joint structure and method of the assembly type steel structure are simpler and more convenient to operate, butt joint and fixation of the beam columns of the steel structure can be achieved without carrying more tools, the labor amount of workers is reduced, and the requirement for professional skills of the workers is lowered.

Description

technical field [0001] The invention relates to the technical field of beam-column structures, in particular to a beam-column tenon-mortise joint structure of an assembled steel structure and an installation method. Background technique [0002] Prefabricated buildings have the advantages of environmental protection and fast construction speed, and have become one of the important directions of future building development. Prefabricated steel structures are one of the important components of prefabricated buildings.
