Embodiment 1

[0022] Embodiment one, as Figure 1-2 As shown, the frame beam-column rigid joints of a single-story steel structure factory building site include frame columns and frame beams, where the frame columns include outer column flanges 1, column webs 2, and inner column flanges 3; frame beams include cantilever beams section and middle beam section; the frame column is connected with a cantilever beam section, and the cantilever beam section includes the upper flange 4 of the cantilever beam section, the web plate 5 of the cantilever beam section, and the lower flange 6 of the cantilever beam section; the upper flange 4 of the cantilever beam section and the inner The column flange 3 and the top of the column web 2 are in contact with the outer column flange 1 with groove penetration welds; the lower flange 6 of the cantilever beam section is welded with the inner column flange 3 with groove penetration welds; The upper flange 4 of the cantilever beam section is welded to the upper ...

Embodiment 2

[0023] Embodiment two, such as image 3 As shown, the difference from Embodiment 1 lies in: the splicing seam between the upper flange of the cantilever beam section and the upper flange of the middle beam section, the splicing seam between the lower flange of the cantilever beam section and the lower flange of the middle beam section, and the web of the cantilever beam section The joints between the slab and the web of the middle beam section are not in the same vertical plane, and the extension length of the lower flange of the cantilever beam section from the flange of the inner column is greater than the extension length of the web of the cantilever beam section from the flange of the inner column , the extension length of the web of the cantilever beam section from the inner column flange is greater than that of the upper flange from the inner column flange.

Embodiment 3

[0024] Embodiment three, as Figure 4 As shown, the difference from Embodiment 1 is that the cantilever beam section and the middle beam section are inclined: the cantilever beam section and the middle beam section are inclined upward along the mid-span direction to facilitate drainage; or the cantilever beam section and the middle beam section are downward along the mid-span direction Inclined to form a single slope roof.

Abstract

The invention relates to a construction site-spliced rigid node of a frame beam and a frame column for a single-layer steel structure workshop, comprising a frame column and a frame beam. The construction site-spliced rigid node is characterized in that the frame column comprises an outer column flange, a column webplate and an inner column flange; the frame beam comprises a cantilever beam section and a middle beam section; the frame column is connected with the cantilever beam section comprising a cantilever beam section upper flange, a cantilever beam section webplate and a cantilever beamsection lower flange; the cantilever beam section upper flange is in contact with the tops of the inner column flange and the column webplate and is welded with the outer column flange; the cantilever beam section upper flange is welded with the upper flange of the middle beam section; the cantilever beam section lower flange is welded with the lower flange of the middle beam section; and the cantilever beam section webplate is in frictional connection with a middle beam section webplate through double clamp plates by adopting high-strength bolts. The node has the advantages of safety and reliability, definite force transfer, simple structure, convenient construction and the like.

Description

technical field [0001] The invention relates to a building node, in particular to a frame beam-column node of a single-story steel structure factory building, which can be widely used in the steel structure single-layer industrial factory building. Background technique [0002] At present, single-story industrial plants mostly adopt steel structures, and their structural systems are generally horizontal plane frames and vertical column support systems. The beams and columns of horizontal plane frames are generally welded H-shaped steel. In order to improve the anti-sway stiffness of the frame, reduce the deflection of the beam, give full play to the material strength of the steel, and reduce the amount of steel used in the frame, it is more reasonable to design the splicing nodes of the beam and the column as a rigid connection, which is now a common method. For: the beams and columns are made separately, the ends of the beams are provided with end plates, and the flanges of...
