Description
Technical field
The utility model relates to a kind of curvature-prevention support component.
Background technology
Traditional structural seismic method is that the strength and stiffness by improving structure itself resist geological process, utilizes ductility and the plastic strain of structure simultaneously, consumes the energy of Seismic input.The shortcoming of this method is in earthquake, mainly rely on the damage of structure self to carry out consumed energy, and geological process is uncertain often, and a large amount of seimic disaster census research also shows, though structure is not collapsed after shake, but serious breakage causes result cannot continue to use, reinforcement cost is high, and reinforcing and reconstruction face a difficult selection and select.Therefore, traditional, passive seismic countermeasures is also inadvisable, particularly in middle and high degree seismic fortification intensity district.Arranging curvature-prevention support component is in the structure the active and effective measure of one improving structural seismic performance.Curvature-prevention support component both can be used for newly-built structure, was applicable to again the seismic hardening of existing structure, simultaneously more obvious to the control effects of highrise building, therefore, was widely used in Practical Project.
Typical curvature-prevention support component is made up of inner core, outsourcing confining part and adhesive-less layer set between the two or gap three part.Wherein support inner core and only bear axle power, only produce axial deformation, confining part then prevents bracing members pressurized lateral buckling by its bending rigidity and anti-bending bearing capacity.At present, conventional on the market main clean steel type of curvature-prevention support component and grouting-type.Wherein, anti-buckling being supported for of clean steel type prevents inner core member self pressurized from surrendering, General Requirements inner core member radius of gyration is larger, mostly be welding compound section, and welded stress and welding residual deformation often affect the overall package of support, welding operation can change the design yield force of inner core, even reduces the low cycle facigue performance of inner core member, and it is higher that clean steel supports general expenses; And the normally internal coreboard of grouting-type curvature-prevention support component carries out gas flame cuttiug process, geometry plane being formed variable cross-section weakens, the power consumption being easy to surrender is formed interval at cross section weakening area, supporting with clean steel, the secondary operations of inner core member reduces mechanical property and the anti-fatigue performance of inner core member.In addition, existing supporting member, connect to meet the strong node in end, general end junction plate all does strengthens process, and namely the thickening of junction plate local or junction plate local size amplify, and this secondary operations have impact on the overall performance of support equally.
Summary of the invention
The purpose of this utility model is to provide a kind of curvature-prevention support component, there is to solve the curvature-prevention support component that existing market uses the overall package that welded stress that secondary operations produces and welding residual deformation often affect support, reduce the problem of the anti-flexion capabilities of inner core member.
The utility model is solve the problems of the technologies described above the technical scheme taked to be:
A kind of curvature-prevention support component, it comprises inner core member, constraint housing, two end plates and four end junction plates, inner core member is steel plate, the thickness of described inner core member is increased progressively to two ends by center, constraint housing is hollow cuboid, the two ends of constraint housing are respectively fixedly connected with an end plate, inner core member is arranged on the end plate that in constraint housing and its two ends are each passed through constraint housing two ends, the often end of inner core member is provided with two end junction plates, an end connecting member in two end connecting member is fixedly connected with the upper surface of inner core member through end plate, another end connecting member in two end connecting member is fixedly connected with the lower surface of inner core member through end plate.
The utility model compared with prior art has following beneficial effect:
In the utility model, inner core member is yi word pattern variable-thickness steel plate, simple structure, installation steps simple and convenient, inner core section form is yi word pattern, variable-thickness steel plate is factory's finished steel plate, and inner core member, without the need to secondary operations, is conducive to the original mechanical property retaining inner core member, improve the anti-flexion capabilities of inner core member, meanwhile, inner core member cross section is less, and the steel using amount of inner core member reduces, be convenient to saving steel, cheap.
