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 and the angle steel 42 are vertically fixedly connected 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 faces 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, the...

Abstract

The invention discloses a combined anti-seismic bolt connection node, comprising a square steel pipe, a connecting end plate, a steel beam, a low-yield positioning piece and a single-sided bolt, wherein the number of connecting end plates is two, and the two connecting end plates are respectively In contact with the outer sidewalls on opposite sides of the square steel pipe. The steel beam is I-shaped or H-shaped, and the number of steel beams is two. One end of the steel beam is vertically fixedly connected to the side wall on the other side of the connecting end plate opposite to the side that contacts the square steel pipe. The two steel beams are connected to the two The end plates are connected one by one, and the flange plate of the steel beam is perpendicular to the axial direction of the square steel pipe. The low-yield positioning piece passes through the square steel pipe and two connecting end plates, and the unilateral bolt passes through a connecting end plate and the side wall of the square steel pipe in contact with the connecting end plate and is embedded in the square steel pipe. The distance between the low-yielding positioning piece and the steel beam The distance between the webs is smaller than the distance between the unilateral bolts and the web of the steel beam. The overall structure of the invention is simple, easy to realize, low in cost, and has good ductility, dissipative earthquake capacity and bearing capacity in application.

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...
