Embodiment Construction

[0020] The preferred examples of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0021] see Figure 1-4 , examples of the invention include:

[0022] A fully assembled three-section anti-buckling energy-dissipating support includes a threaded joint 1, a buckling energy-dissipating section 2, a flange connection 3 and an elastic support section 4.

[0023] In this embodiment, the threaded joint 1 is directly processed from the core energy-dissipating steel pipe 202, and its overall length is slightly larger than the depth of the sleeve at the construction site. Smooth installation in the environment, at the same time, the length of the anti-buckling support can be adjusted by controlling the depth of the thread into the sleeve d...

Abstract

The invention discloses a full-assembly three-section anti-buckling energy dissipation support, and relates to the technical field of anti-seismic disaster prevention of a building structure. The full-assembly three-section anti-buckling energy dissipation support comprises threaded joints, buckling energy dissipation sections at two ends, an elastic supporting section in the middle and a flange connection. The energy dissipation damping of a whole anti-buckling supporting component is mainly realized by core energy dissipation steel pipes and shape memory alloy springs of the buckling energydissipation section; the threaded joints are formed by machining one ends of the core energy dissipation steel pipes; the elastic supporting section is composed of an elastic supporting steel pipe; and the buckling energy dissipation sections and the elastic supporting section are connected by a flange to form a whole anti-buckling energy dissipation support. In this way, the operations of field assembly, installation, maintenance, replacement and the like in adverse environments such as high altitude can be achieved, and meanwhile the partial self-resetting capability is achieved.

Description

technical field [0001] The invention relates to the technical field of earthquake resistance and disaster prevention of building structures, in particular to a fully assembled three-stage buckling-resistant energy-dissipating support. Background technique [0002] Large-span spatial structures are widely used in practical engineering. The members of such large-scale structures may buckle under accidental loads such as earthquakes, which may lead to the destruction of the overall structure. In order to prevent such damage, an effective measure is to set anti-buckling braces in it. Among them, the buckling-resistant bracing with reinforced concrete as the main material is not suitable for long-span spatial structures because of its large self-weight. The anti-buckling support mainly made of traditional metal materials can reduce its own weight, but it is inconvenient to install at high altitude in a long-span space structure, and its length is also inconvenient to adjust. Th...
