Problems solved by technology

[0004] However, since the rectangular CFST column is a closed solid section, it cannot be operated from the inside of the column when it is connected to the H-shaped steel beam by ordinary high-strength bolts, resulting in difficulties in design and construction. Therefore, there is still a lack of simple and efficient rectangular CFST columns and H-shaped beams The prefabricated joint form of steel beams seriously hinders the popularization and application of prefabricated steel structure residential systems

Embodiment 1

[0047] Such as Figure 1-7 As shown, the bending damper 9 is an S-shaped bending damper, and the bending energy dissipation plate 11 is an S-shaped energy dissipation plate with a bending angle of 90 degrees. The S-shaped energy dissipation plate is provided with a gap at one end connecting the side plate 10 with the damper. Convenient high-strength bolt 8 installation. The damper connects the side plate 10 and the channel steel connector 4 at the beam end to leave a gap required for node rotation.

Embodiment 2

[0049] Such as Figure 8-11 As shown, the bending damper 9 is an S-shaped bending damper, the bending energy dissipation plate 11 is an S-shaped energy dissipation plate, and the bending angle is 60 degrees. The S-shaped energy-dissipating plate is provided with a gap at one end connecting the side plate 10 with a damper to facilitate the installation of the high-strength bolt 8 . The damper connects the side plate 10 and the channel steel connector 4 at the beam end to leave a gap required for node rotation.

Embodiment 3

[0051] Such as Figure 12-16 As shown, the curved damper 9 is a U-shaped curved damper, the curved energy dissipation plate 11 is a U-shaped energy dissipation plate, and the arc convex surface of the U-shaped energy dissipation plate faces the rectangular CFST column 1 . The space required for deformation is left between the U-shaped energy dissipation plate and the rectangular CFST column 1, and the damper connecting side plate 10 is only welded to one end of the U-shaped energy dissipation plate.

[0052] A method for installing beam-column joints of an easily repairable assembled steel structure with a damper, step (1): welding the plate-mounted connector 3 at the column end to both sides of the rectangular CFST column 1, and welding the channel-steel connector 4 at the beam end to the H The upper flange, lower flange and web end of the shaped steel beam 2;

[0053] Step (2): The column-end plate-mounted connector 3 is connected to the beam-end channel-steel connector 4 t...

Abstract

The invention discloses an easy-to-repair assembly type steel structure beam-column joint with a damper and a mounting method. The easy-to-repair assembly type steel structure beam-column joint comprises a rectangular concrete filled steel tube (CFST) column, an H-shaped steel beam, connecting pieces and the bent dampers, the connecting pieces comprise column end flitch connecting pieces, beam end channel steel connecting pieces, bolts and hinge pins, the column end flitch connecting pieces are welded to the two sides of the column, the beam end channel steel connecting piece is welded to an upper flange, a lower flange and the web end of the H-shaped steel beam, the column end flitch connecting piece is connected with the beam end channel steel connecting piece through a hinge pin, the upper side and the lower side of the beam end are each provided with one bent damper, and the two ends of the beam end are connected with the column end flitch connecting piece and the flanges of the H-shaped steel beam correspondingly. The joint is connected only through two side plates at the column end, so that the bent damper is convenient to replace, and meanwhile, processing, manufacturing and on-site installation are very convenient; and the hinge pin and the bending type damper work together, and organic combination of the three functions of bearing, energy consumption and easy repairing is achieved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an easily repairable assembled steel structure beam-column node with a damper and an installation method. Background technique [0002] The prefabricated steel structure has the advantages of light structure weight, small cross-sectional size, good seismic performance, fast construction speed, green recyclability, and convenient component replacement and maintenance. It is a structural form vigorously promoted in my country. Recoverable functional structure refers to the structure that can restore its function without repair or minor repair after the earthquake. Prefabricated steel structure nodes often adopt the method of on-site bolt splicing, which is convenient for setting replaceable energy-consuming parts at the node position, forming a node with good energy dissipation performance and quick repair. This kind of steel structure with good energy consumption...
