Problems solved by technology

However, most of the current replaceable coupling beams reduce energy consumption through sliding friction. The coupling beam mechanism in the sliding friction energy consumption mode is not stable enough, and it is still prone to structural damage during earthquakes, and the existing replaceable couplings The beam also does not have any self-resetting ability

Embodiment 1

[0034] Such as Figure 1-6As shown, this embodiment provides a self-resetting replaceable connecting beam, which includes two sets of replaceable sections and short beam sections placed at both ends of the replaceable sections, and the two sets of replaceable sections are arranged side by side with the short beam sections connection; the short beam section includes a short beam 1, a pre-embedded steel plate 2, an end plate 3 and two sets of short steel plates 4; one end of the short steel plate 4 has a round hole; one side of the end plate 3 is connected to two One end of the short steel plate 4 without holes is connected, and the other side is connected to the end of the embedded steel plate 2. The short beam 1 is provided with two groups, which are respectively arranged on the end plate 3 and connected with the embedded steel plate 2. On the adjacent sides of the end, the pre-embedded steel plate 2 is pre-embedded in the short beam 1 and extends to the end of the short beam ...

Embodiment 2

[0046] Such as Figure 5-9 As shown, this embodiment provides a self-resetting replaceable connecting beam, the overall structure of which is the same as that of the self-resetting replaceable connecting beam in Embodiment 1, the only difference is that the short steel plate 4 and the friction backing plate in this embodiment 10 are connected by a plurality of small bolts. Adaptive selection can be made according to specific conditions during construction.

[0047] Such as Figure 9 As shown, the present invention provides a self-resetting replaceable coupling beam, in which the friction backing plate 10 is connected with the short steel plate 4 through a plurality of small bolts, and when an earthquake occurs, the short steel plate 4 and the friction backing plate 10 are simultaneously Rotate around the bolt 5, and the plane where the friction backing plate 10 is in contact with the long steel plate 11 produces rotational friction. The rotational friction generated during t...

Abstract

The invention discloses a self-resetting replaceable coupling beam which comprises two groups of replaceable sections and short beam sections arranged at the two ends of each replaceable section. Thetwo groups of replaceable sections are connected with the short beam sections side by side; each short beam section comprises a short beam, a pre-buried steel plate, an end plate and two groups of short steel plates; each replaceable section comprises a long steel plate, a bolt, a nut, a friction base plate, a disc spring and a shape memory alloy wire harness, the disc spring, the long steel plate, the friction base plate and the short steel plate are connected through the bolt and fixed by the nut, and the shape memory alloy wire harness is arranged at the outer end of one or two sides of thebolt in a crossed mode and is fixed by the nut. The self-resetting replaceable coupling beam can be applied to important building structures of high-intensity earthquake regions, has high energy consumption capability, the replaceable capability and the excellent self-resetting capability, and is high in structure stability and capable of being widely applied to the field of various building structures with recoverable functions.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structural systems, in particular to a self-resetting replaceable connecting beam. Background technique [0002] Combined shear wall is a lateral force-resisting structural system widely used in high-rise building structures, and coupling beams are important energy-dissipating components in combined shear wall structures. safety. However, it is difficult and expensive to repair or replace the shear brittle failure or bending failure of the traditional reinforced concrete coupling beam, steel coupling beam or steel concrete composite coupling beam. In recent years, some scholars at home and abroad have begun to study replaceable coupling beams, so that the coupling beams can be easily repaired or replaced after damage, and the cost of coupling beam repairs can be reduced. However, most of the current replaceable coupling beams reduce energy consumption through sliding friction. The coupling ...
