Triple-level metal rectangular pipe flection restriction support energy-dissipation device

Abstract

The invention relates to a triple metal rectangular pipe bending restricting supporting energy consumer. A core stressed member consists of a core stressed rectangular pipe (1), an inner restricting rectangular pipe (2) and an outer restricting rectangular pipe (3), wherein, the core stressed rectangular pipe (1) is arranged between the inner restricting rectangular pipe (2) and the outer restricting rectangular pipe (3), and the length thereof is larger than the length of the inner restricting rectangular pipe (2) and the outer restricting rectangular pipe (3); pilot pins (4) are used to fix one end of the core stressed rectangular pipe (1), the inner restricting rectangular pipe (2) and the outer restricting rectangular pipe (3); in the middle part of the core stressed rectangular pipe (1), 4 long grooves (4) are arranged along the periphery of the pipe with equal distance; stream guidance holes (102) are arranged on the core stressed rectangular pipe (1). The inner and outer rectangular pipes restrict local bending of the core stressed rectangular pipe and provide bending rigidity for preventing the overall bending of the energy consumer; the pilot pins are used to fix the relative position between the triple metal rectangular pipes.

Description

technical field [0001] The invention relates to a buckling-constrained support energy-dissipating shock absorber, which belongs to the field of civil engineering and can be used to build or reinforce building engineering structures to improve its overall energy-dissipating capacity, thereby improving the structure's anti-seismic capacity and safety. Background technique [0002] Under normal use or under the action of frequent earthquakes, the buckling restrained support energy dissipator is used as a structural component to provide effective support for the structure; under the action of basic intensity earthquakes or rare earthquakes, it will use the yield and hysteresis properties of metals to dissipate energy The energy input by the earthquake reduces the damage of the main structure and can be easily replaced after the earthquake. [0003] Existing buckling-constrained braced dissipators generally consist of core load-bearing components, buckling-constrained components,...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of concrete or mortar, it will adversely affect the production, installation and performance of energy consumers

At the same time, due to the discreteness of the quality of concrete or mortar, it also affects the stable performance of the energy consumption performance of the energy consumer

Another problem with existing buckling-restrained bracing dissipators is to protect the non-buckling section by enlarging the end section, but this often increases the difficulty in manufacturing
