Description
Technical field:
This utility model relates to Construction Anti-earthquake and energy-dissipating and shock-absorbing technical field, particularly relates to a kind of assembled anti-buckling support of high-mechanic type.
Background technology:
A large amount of along with China's infrastructure build and high speed development, and the structure such as high-rise building, Loads of Long-span Bridges is constantly emerged in large numbers in China area of providing fortification against earthquakes.Owing to China is one of country of taking place frequently most of earthquake in the world, almost there is ruinous earthquake to occur every year, the safety of life property and infrastructure will be brought huge harm.High-rise building carries critical effect with long-span bridges etc. in social and economic development, alleviates the damage under earthquake of this class formation and has great importance.
Curvature-prevention support component is a kind of lateral resistant member with energy-dissipating and shock-absorbing effect, is typically made up of with peripheral constraint component two parts kernel core component.Size is unified along length in the cross section of component, and uses commaterial to be uniformly distributed.This building method, in high-rise building or Loads of Long-span Bridges, needs to be designed to the buckling restrained brace of super-tonnage and length.Further result in supporting member easily to form stress in centre and concentrate, and ultimately resulted in that out-of-plane deformation is excessive and disabler.
In the Aseismic Design of modern heavy construction structure, it is desirable to strictly control the permanent damage of agent structure.Accordingly, it would be desirable to huge energy-dissipating and shock-absorbing component can replace structure to undertake earthquake load effectively.One effective solution is to be uniformly embedded into some antivibrators along buckling restrained brace length direction so that it is alongst homogeneous deformation, significantly reduces the probability that complete buckling occurs, adds deformation and energy dissipation capacity simultaneously.
Utility model content:
The purpose of this utility model is to solve the problems of the prior art, one is provided to can be applicable in building structure, play and undertake seismic force, the effect of dissipation seismic energy, meet super-high building structure and large-span structure to bearing capacity and the assembled anti-buckling support of high-mechanic type of power consumption demand.
In order to achieve the above object, the technical solution of the utility model is:
The anti-buckling support of assembled high-mechanic type, including anti-buckling support body, described anti-buckling support body includes dissipative member and the buckling-restrained bracing member installed at coaxial and interval, and the two ends of described anti-buckling support body are all coaxially installed with dissipative member；Described buckling-restrained bracing member includes that outer steel pipe, described outer steel duct are filled with high-strength concrete layer；The two ends of described dissipative member and buckling-restrained bracing member are mounted on cover plate, are weldingly connected by cover plate between adjacent described dissipative member and buckling-restrained bracing member；Described anti-buckling support body interior is provided with prestressed cable, and described prestressed cable is axially through dissipative member and buckling-restrained bracing member, and is connected with the cover plate anchoring of the dissipative member at anti-buckling support body two ends by high-strength bolt.
Described dissipative member is metal damper.
Described dissipative member is the short steel pipes that Low Yield Point Steel is made.
The sectional area of described buckling-restrained bracing member is less than the sectional area of dissipative member.
The cross section of described buckling-restrained bracing member is circular or square-section, and the cross section of described dissipative member is square-section.
The beneficial effects of the utility model are: the assembled anti-buckling support of high-mechanic type of the present utility model, use the direct load of steel pipe and the building method of power consumption, have saved steel and constructions cost；By using multistage separate type to construct, reducing the overall collapse concentrated and occur due to stress, improve buckling restrained brace has the advantage of high bearing capacity in the case of large deformation, adds the component suitability under big shake effect and overall stability；Dissipative member and buckling-restrained bracing member coaxial spaced are installed, has coordinated the rigidity of buckling-restrained bracing member and the relation of bearing capacity neatly.
