Embodiment Construction

[0037] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0038] The principle of the present invention is that, based on the principle that the column of the frame structure mainly undergoes unidirectional bending deformation below the inflection point during earthquake action, by arranging resistance cables and energy-dissipating cables below the inflection point of the bottom column of the frame structure, the main use of the resistance force The cables apply countermoment to the bottom frame columns to reduce the bending moment of the frame structure bottom columns and beams, and the repeated deformation of the energy-dissipating cables is used to dissipate the energy input by the earthquake into the structure.

[0039] Specifically, the present invention includes an anchor plate 2, a first connecting piece 6, a bolt 7, a spring washer 8, a steel plate stiffener 9, and embedded parts (if it is a re...

Abstract

The invention relates to an energy-consuming shock absorber, belonging to the field of construction. The energy-consuming shock absorber mainly comprises an anchor fixing plate, a power resistance cable and an energy-consuming cable. The anchor fixing plate is welded nearby the underneath of an inflection point of a framework column in a bottom layer, the upper ends of the power resistance cable and the energy-consuming cable are connected with the anchor fixing plate by components of the anchor fixing plate, a cable wire connector and the like, and the lower ends of the power resistance cable and the energy-consuming cable are fixed under ground. The energy-consuming shock absorber has simple structure, convenient construction and reliable power transmission, as well as simple replacement and maintenance in the condition of being destroyed by the earthquake, thus being capable of being used for reducing the earthquake response of the framework structure, and preventing or reducing the damage of the bottom layer column of the framework structure under the earthquake.

Description

technical field [0001] The invention belongs to the field of construction, and relates to an energy-dissipating and shock-absorbing device of a frame structure, which can be used to reduce or avoid the seismic response of the bottom column of the frame structure, thereby reducing or avoiding the shock damage of the bottom column of the frame structure. Background technique [0002] Since the frame structure is dominated by shear deformation, the lateral displacement deformation of the bottom column of the structure is the largest. Therefore, under the action of earthquakes, the bottom column of the frame structure is more likely to be damaged. Judging from the damage of the frame structure in the Sichuan Wenchuan Earthquake on May 12, 2008, many frame structures were damaged at the bottom of the column, and it was very difficult to repair after the earthquake. Therefore, improving the seismic performance of the ground-floor columns of frame structures has become an urgent pr...
