Embodiment 1

[0032] Such as Figure 1 ~ Figure 3 As shown, a combined anti-seismic bolt connection node includes a square steel pipe 1, a connecting end plate 2, a steel beam 3, a low-yield spacer 5 and a single-sided bolt 6, wherein the connecting end plate 2 is rectangular, and its number is Two pieces, the two connecting end plates 2 are respectively parallel to and in contact with the outer side walls of the opposite sides of the square steel pipe 1 . The steel beam 3 of this embodiment is I-shaped or H-shaped, and the number of steel beams 3 is two. One end of the steel beam 3 is vertically fixedly connected to the side wall of the other side of the connecting end plate 2 that is in contact with the side of the square steel pipe 1. , the two steel beams 3 are connected to the two connecting end plates 2 in one-to-one correspondence, and the flange plates of the steel beams 3 are perpendicular to the axial direction of the square steel pipe 1 . In this embodiment, when specifically co...

Embodiment 2

[0044] Such as Figure 4 As shown, the present embodiment has made the following improvements on the basis of Embodiment 1: the present embodiment also includes an angle steel limit piece 4, wherein the angle steel limit piece 4 includes a limit tube 41 and an angle steel 42, and a piece of the angle steel 42 The rectangular panel is in contact with the web of the steel beam 3 and is fixed on the web of the steel beam 3 by positioning bolts 43 , and the other rectangular panel is parallel to the connecting end plate 2 . In this embodiment, the limiting tube 41 is vertically fixedly connected to the angle steel 42 parallel to the outer sidewall of the rectangular panel connecting the end plate 2 , and one end of the limiting tube 41 not connected to the angle steel 42 is facing the connecting end plate 2 . In this embodiment, each steel beam 3 is connected with an angle steel limit piece 4, and the end of the low yield locator 5 is embedded in the limit tube 41, specifically, t...

Abstract

The invention discloses a combined type damping bolted connection joint. The combined type damping bolted connection joint comprises a square steel tube, two connection end plates, two steel beams, a low-yield positioning piece and an unilateral bolt, wherein the two connection end plates are in contact with the outer side walls of the two opposite sides of the square steel tube. The steel beams are in an I shape or an H shape, one end of each steel beam is vertically and fixedly connected to the side wall of another side, opposite to the side in contact with the square steel tube, of the corresponding connection end plate, the two steel beams are connected with the two connection end plates in a one-to-one corresponding mode, and flange plates of the steel beams are perpendicular to the axis direction of the square steel tube. The low-yield positioning piece penetrates through the square steel tube and the two connection end plates, the unilateral bolt penetrates through one connection end plate and the side wall, in contact with the connection end plate, of the square steel tube, and is inlaid in the square steel tube. The distance between the low-yield positioning piece and a web of each steel beam is shorter than the distance between the unilateral bolt and the web of each steel beam. The combined type damping bolted connection joint is simple in the whole structure, convenient to achieve, and low in cost, and has good ductility, earthquake dissipating capability and bearing capability when being applied.

Description

technical field [0001] The invention relates to the technical field of building anti-seismic connection, in particular to a combined anti-seismic bolt connection node. Background technique [0002] In recent years, the frame system of civil and industrial construction projects is often applied to square steel pipes. Compared with traditional hot-rolled H-shaped steel, square steel pipes can avoid the difference in flexural modulus between the strong axis and the weak axis, and can be better in the frame system. It exerts its bearing capacity and saves steel, and its smaller external area makes its anti-corrosion and fire resistance better. At present, the fixed common joint forms of square steel pipes in the frame system are as follows: (1) Chinese Patent Publication No. CN 103510626A disclosed a top-bottom angle steel H-shaped steel beam and a rectangular pipe column unilateral bolt connection joint on January 15, 2014. It includes a rectangular pipe column, an H-shaped st...
