Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] figure 1 It is a structural schematic diagram of the present invention, which is composed of an end restraint section 1 , an energy dissipation section 2 and a casing 3 . The end restraint section 1 is fixed between the beam-column node and the energy dissipation section 2 .

[0022] Such as figure 2 As shown, the end restraint section 1 is composed of a square steel plate 4, a T-shaped short steel beam 5, and a connecting plate 6 reserved for components such as beams and columns. The square steel plate 4 is welded to the end of the energy dissipation section 2. Two T-shaped short steel The beam 5 is welded to the square steel plate 4, and the square steel plate 4 and the T-shaped short steel beam 5 are respectively shown in Figure 5 , 6 shown. The connecting plate 6 is sandwiched between two T-shaped short steel beams 5, and the connecting plate 6 and th...

Abstract

The invention discloses a sleeve restraint anti-buckling support provided with bidirectional pyramid-shaped energy dissipation units. The sleeve restraint anti-buckling support provided with the bidirectional pyramid-shaped energy dissipation units is characterized in that the sleeve restraint anti-buckling support is composed of end restraint sections, energy dissipation sections and a sleeve, and the two ends are connected into with beam or column components or joints into a whole through bolts, so that the purpose of increasing the resistant-lateral rigidity of a component is achieved. By the adoption of the sleeve restraint anti-buckling support provided with the bidirectional pyramid-shaped energy dissipation units, under the small shock action, the sleeve restraint anti-buckling support can be kept elastic; and under the medium or great shock action, the energy dissipation sections are switched to the buckling stage, and a damper effect can be achieved through the good hysteretic energy dissipation performance of the energy dissipation sections. The sleeve restraint anti-buckling support provided with the bidirectional pyramid-shaped energy dissipation units can be prefabricated in a factory, the quality of the component is guaranteed, the field construction workload is reduced, energy is saved, and environmental friendliness is achieved.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a casing-constrained anti-buckling support with bidirectional pyramid-shaped energy-dissipating units, which is suitable for steel structures or concrete structures with buckling-constrained supports. Background technique [0002] During the use of steel structures or reinforced concrete structures, ordinary supports will buckle under compression. When the supports buckle under compression, the stiffness and bearing capacity will decrease sharply. Under the action of earthquake or wind, the internal force of the support changes back and forth under the two states of compression and tension. When the support gradually changes from the buckling state to the tension state, the internal force and stiffness of the support are close to zero. Therefore, the hysteretic performance of ordinary supports is poor under repeated loads. In order to solve the problem o...
