Double-core prestressed tension self-restoring energy dissipation supporting device

Abstract

The invention relates to a double-core prestressed tension self-restoring energy dissipation supporting device, which is installed on a building and comprises a fist core component, a second core component, an outer component, two inner bottom boards, two outer bottom boards, a plurality of prestressed tension components and an energy dissipation unit. The outer component covers the first core component and the second core component. The two inner bottom boards are disposed at two ends of the first core component respectively, and the two outer bottom boards are disposed at two ends of the outer component respectively. The energy dissipation unit is used for dissipating energy of relative displacement between the first core component and the outer component. The prestressed tension components with two end fixation forms respectively generate elongation delta when stressed, so that relative displacement between the first core component and the outer component reaches 2delta, and seismic energy is dissipated through the energy dissipation unit.

Description

technical field [0001] The invention relates to an energy-dissipating support device, in particular to a double-core pre-stress stretching self-resetting energy-dissipating support device with increased extension. Background technique [0002] In the current earthquake-resistant design, in addition to having sufficient allowable strength, it is also desirable to have good toughness in order to achieve more economical and safer goals. As far as structural systems that use buckling to dissipate energy usually cause residual permanent deformation after large deformations, the building will have residual stress and cause potential danger, requiring future repairs to solve this problem. At present, the common support system is mainly based on the buckling or buckling of structural members to dissipate energy. However, under repeated loads, the deformation caused by buckling or buckling will affect the safety of the building structure and the difficulty in rescue. Spend. The res...

However, limited by the material properties of the tension rod, the axial deformation of the device is limited to δ

[0008] It can be seen that the above-mentioned existing self-resetting energy-dissipating support device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
