Self-resetting anti-buckling support under tension and compression

An anti-buckling support and self-resetting technology, which is applied in the direction of earthquake resistance and building components, can solve the problems that the anti-buckling support has no self-resetting function, cannot self-reset the main structure, and deforms between layers of the main structure, so as to achieve applicable safety and reduce Interlayer displacement angle, effect of prolonging service life

Problems solved by technology

[0002] Under the action of moderate earthquake and large earthquake, the main structure of the engineering building will produce certain interstory deformation. Although the use of traditional anti-buckling bracing can consume part of the energy of the earthquake, the main structure will still have interstory deformation. Due to the traditional anti-buckling The support has no self-resetting function, and it cannot make the main structure self-reset by relying on the anti-buckling support members after being deformed. However, the existing self-resetting anti-buckling supports can only have self-resetting function after tension, and cannot be reset under compression, and the structure quite complicated

Embodiment 1

[0021] A self-resetting anti-buckling support under tension and compression, including a core material, the middle section 101 of the core material is a "one"-shaped structure, and the two ends are reinforcement sections 102 with a "ten"-shaped structure. The anti-buckling support also includes a left end plate 3. The right end plate 11, the front T-shaped steel plate 7, the rear T-shaped steel plate 10, four force-transmitting steel pipes and the reset rib 5 located in the middle cavity of the force-transmitting steel pipe. The structures of the left and right end plates are the same, and there are four The lead-out hole for the protruding end of the reset rib and the cross groove for the "ten" shaped core material of the reinforced section to protrude. The left and right end plates are respectively located at the two ends of the core material and set on the reinforced section at both ends of the core material. 102 on the end of the "ten" shaped core material.

Embodiment 2

[0028] A self-resetting anti-buckling brace under tension and compression, the basic structure of which is the same as that of Embodiment 1, except that the shape of the cross-section of the force-transmitting steel pipe is rectangular.

Embodiment 3

[0030] A self-resetting anti-buckling support under tension and compression, the basic structure of which is the same as that of Embodiment 1, except that the shape of the cross-section of the force-transmitting steel pipe is circular.

[0031] working principle:

[0032] When the anti-buckling support is subjected to tension and compression axial force, under the action of the restraint unit composed of the front and rear T-shaped steel plates and the middle plate, the core material can fully yield when it is under tension and compression, and it will not buckle under compression, thus giving full play to the hysteresis of the steel. Return energy consumption.

[0033] Since the two ends of the force transmission steel pipe are welded diagonally to the two ends of the core material, when the core material is pulled, the welded ends of the two sets of force transmission steel pipes move toward the two sides together with the ends of the core material. When the displacement is...

Abstract

A tension and compression self-resetting anti-bending support comprises a core material, a left end plate, a right end plate, a front T-shaped steel plate, a rear T-shaped steel plate, four force-transmitting steel pipes and resetting ribs located in middle cavities of the force-transmitting steel pipes. The left end plate and the right end plate are respectively sleeved at the ends of cross core materials positioned at two ends of the core material, the force-transmitting steel pipes are respectively located in four right-angle areas of the cross core materials and adhere to a facade of the core material, the left ends of the force-transmitting steel pipes located on in the upper left right-angle area and the lower right right-angle area are fixedly welded to the adjacent cross core materials, the front T-shaped steel plate and the rear T-shaped steel plate are installed in a middle section of the core material and connected through a bolt assembly to clamp a --shaped core material, and two ends of the resetting ribs respectively penetrate out of the left end plate and the right end plate and are fixedly connected with the left end plate and the right end plate through locking nuts. The tension and compression self-resetting anti-bending support is reasonable in design, transmits force evenly and is safe and reliable, and self-resetting can be achieved through elastic deformation capability of the tension and compression self-resetting anti-bending support.
