Problems solved by technology

[0005] The purpose of this invention is to create a new type of column-column-beam integrated assembly joint and its construction method suitable for square steel pipe columns and H-beam frame systems. It is expected to solve the column-column-beam integrated assembly at the same time through one node Solve the problem that the existing nodes can only achieve a single column-column or column-beam assembly connection, realize the pure assembly connection in the true sense of this type of system, and increase the convenience of node construction to a greater extent

specific Embodiment approach 1

[0034] refer to Figure 1-6 , in an embodiment of the present invention, a column-column-beam assembly type integrated variable beam height node, the node includes a steel pipe column section 1 above the node area, a steel pipe column section 2 below the node area, and an H-shaped steel beam section 3 in the node area and connectors, the connectors include T-shaped flange plate 4, lower column square flange plate 5, ear plate 6, end plate 7 and independently arranged connector 8; T-shaped flange plate 4 is welded to the upper steel pipe column section 1 , the square flange plate 5 and ear plate 6 are welded to the lower steel pipe column section 2, and the end plate 7 is welded to the H-shaped beam section 3; cutting to avoid collision between the square flange plate 5 and the H-shaped steel beam during installation.

specific Embodiment approach 2

[0036] The T-shaped flange plate 4 of the upper column and the square flange plate 5 of the lower column are connected by high-strength bolts, and the axial force, shear force and bending moment of the upper column are transmitted to the lower column section to realize the connection of the upper and lower steel pipe columns. The H-shaped beam 2 The upper flange is connected to the T-shaped flange plate 4 of the upper column through high-strength bolts, and the lower flange is connected to the ear plate 6 on the column side through the connecting piece 8 and high-strength bolts, so as to transmit the bending moment and shear force of the beam section to the ear plate, realizing the H-shaped The steel beam is connected to the square steel pipe column, and then the integrated connection of column-column-beam assembly is realized at the same time.

specific Embodiment approach 3

[0038] The ear plates 6 are symmetrically welded on both sides of the lower steel pipe column 2, aligned with the outer edge of the column, and the ribs are welded inside the column, and connected with the connector 8 through high-strength bolts. The connecting piece 8 is groove-shaped, and its width is equal to the difference between the width of the column and the thickness of the ear plate. The connecting piece 8 is arranged between two ear plates 6, and forms a reliable connection with the ear plate 6 on the column side and the lower flange of the steel beam through high-strength bolts; The lug plate 6 has an oblong hole 9, and the bolt connected to the connector 8 can slide freely up and down in the oblong hole. During implementation, the installation elevation of the connector 8 can be freely adjusted according to the height of the H-shaped beam 2, so that the same node can be adapted to different heights. The connection of H-shaped beams increases the versatility of the ...

Abstract

The invention relates to a column-column-beam assembly type integrated variable beam height node and a construction method thereof. The node includes a steel pipe column section above the node area, a steel pipe column section below, an H-shaped steel beam section in the node area and independently arranged connectors. The end of the upper steel pipe column is equipped with a T-shaped flange plate, the end of the lower steel pipe column is equipped with a square flange cover plate and the side is provided with an ear plate, and the flange plate of the upper column is connected with the flange plate of the lower column through high-strength bolts to realize Column-column assembly connection; the upper flange of the H-shaped steel beam is connected to the T-shaped flange plate of the upper column through high-strength bolts, and the lower flange is connected to the ear plate of the lower column through high-strength bolts and connectors to realize the prefabricated connection of column-beam. And the lower part of the lug plate is provided with a long round hole, the height of the bolts connected to it can be adjusted to realize the assembled connection of H-shaped steel beams of different heights, with zero welding on site, and the assembled connection of column-column and column-beam can be realized at the same time. It has a series of advantages such as good versatility, no damage to steel pipes, and more convenient construction and transportation.

Description

technical field [0001] The invention relates to a building steel structure node and a construction method thereof, in particular to a column-column-beam integrated assembled node of a square steel pipe column and an H-shaped steel beam in a steel structure and a construction method thereof. Background technique [0002] The prefabricated steel structure has a series of advantages such as light weight, high strength, good seismic performance, quick construction, short cycle, reusable use, and less pollution. It is an important part of my country's construction industrialization and has good application prospects and market potential. The degree of assembly of the steel structure mainly depends on the connection form of its component nodes. [0003] Square steel pipe is the main vertical force member often used in steel structures, and "H" steel is also the most commonly used transverse force member. The column-to-column connection of square steel pipes is mainly welded. The ...
