Inverted-V-shaped assembly type combined energy-dissipating, damping and supporting device

Abstract

The invention discloses an inverted-V-shaped assembly type combined energy-dissipating, damping and supporting device. The inverted-V-shaped assembly type combined energy-dissipating, damping and supporting device comprises a primary supporting part (1), wherein one side of any one end of the primary supporting part (1) is movably equipped with a secondary supporting part (2); the other side of any one end of the primary supporting part (1) is movably equipped with a viscous damper (3). The curved-shaped secondary supporting part of the damping supporting device and the viscous damper can separately generate distortion flexion and axial telescopic deformation under action of an earthquake, and can co-dissipate earthquake energy; compared with a conventional soft steel damping support and the viscous damper, the inverted-V-shaped assembly type combined energy-dissipating, damping and supporting device has greater energy-dissipating ability and design flexibility, can be applied to energy-dissipating and damping of reinforcement concrete and a steel framework structure better; and meanwhile, the inverted-V-shaped assembly type combined energy-dissipating, damping and supporting device has the characteristics of full assembly type, mixed damping, simple and convenient mounting, easy replacement after earthquake damages, small mounting difficulty, low manufacturing cost and easy transportation, and is applicable to energy-dissipating, damping and supporting of the reinforcement concrete and the steel framework structure.

Description

technical field [0001] The invention relates to a shock-absorbing support device, in particular to a herringbone-shaped assembled combined energy-dissipating and shock-absorbing support device, which is mainly used in energy-dissipating and shock-absorbing structures such as buildings, bridges, and railways, to achieve energy dissipation that is difficult to dissipate. The expected earthquake energy belongs to the field of anti-seismic technology of construction engineering. Background technique [0002] Generally speaking, due to the acceleration of the urbanization process in our country, the urban population density continues to increase, and the height, breadth and complexity of urban buildings have been constantly breaking records. In order to avoid or reduce the impact of earthquake disasters on building structures, since the 1970s, people have gradually applied mild steel and viscous dampers to structural projects such as buildings, bridges, and railways. , using dam...

[0005] And a utility model patent whose notification number is CN2725397 proposes a kind of small eight-shaped bell crank support type frame, and the fixed connection of each bolt of this small eight-character figure eight bell crank support type frame is a rigid fixed connection, when the building is subjected to horizontal When the force is applied, the connection node between the support and the building is easily damaged, and it is cumbersome to replace after damage. While increasing the labor intensity of the construction personnel, it cannot achieve a good shock absorption effect, and more importantly, there is a greater safety hazard; The damper of the small figure-eight bellcrank bracing frame is arranged at the corner of the building frame, the displacement stroke of the damper deformation is limited, and the advantages of the large stroke of the damper cannot be effectively utilized, so the small figure-eight bellcrank is installed Buildings with bracing frames cannot effectively resist large earthquakes, which is unfavorable for energy dissipation and shock absorption of buildings; at the same time, the small eight-shaped crank-crank bracing frame is only arranged with one type of damper, which belongs to single-function damping Shock device, single function
