Description
Technical field
The present invention relates to a kind of all steel curvature-prevention support component, is a kind of anti-buckling support structure of T-shaped assembled specifically
Part, being mainly used in can dissipating in construction of structures seismic energy and significantly improves the uniaxial force component of structural seismic performance.
Background technology
Because the anti-buckling support of all steel type has from heavy and light, outstanding advantages of simple processing, obtained in engineering a large amount of
Application, wherein it is more using yi word pattern and cross section shaped steel as inner core.Cut because in the market does not produce cross inner core
Face, it is therefore desirable to be welded using three blocks of steel plates, the core space of yi word pattern section inner core and the variable cross-section of transition region are often
Need to complete by welding, this processing method has the following disadvantages：
（1）The initial geometrical defect of inner core
Cross inner core can produce four weld seams in process, and a large amount of high temperature thermal stress caused by welding are easily led
Inner core is caused to produce larger welding residual deformation, this residual deformation can cause bracing members inner core to be difficult to insert steel duct, especially
It is when bearing length is longer, carrys out technical difficulty to the assembled belt of support.In addition, this welding residual deformation can also reduce steel
Material it is moulding, the stability of support can also be adversely affected；
（2）The inconsistency of actual performance and design performance
The actual measurement surrender axle power of cross inner core all steel curvature-prevention support component is bent than the design for testing to obtain according to material
Take that axle power is high by about 40%, the presence that this result of analysis shows is primarily due to section of weld joint area causes core section face in reality
Product increase, while the yield stress of weld seam is typically higher than core yield strength, so as to cause measured performance and design performance not
Uniformity.The deviation of this actual performance may result in anti-buckling support can not be in the earthquake intensity that designer is expected
Surrender power consumption just occurs, and then influences the actual anti-seismic performance of structure；
（3）The adverse effect of welding
The cross and inner core of yi word pattern inner core curvature-prevention support component of existing various constraint types is more using welding
Fixing mechanism, inner core welding can have a negative impact to its low cycle fatigue property so as to cause the moulding energy dissipation capacity of inner core to play not
Fully, low-cycle fatigue fracture occurs to early.Will than the low cycle fatigue property of welding inner core using the inner core that welding processing makes
It is low, in addition, the welding of outer tube and strengthening being welded on while bury hidden danger of quality of area, also increase difficulty of construction and making
Duration；
Because the existing cross and yi word pattern innercore construction using welding technique can assembling, stably to supporting member
Property, mechanical property and low cycle fatigue property have a negative impact, and the inner core used in order to avoid welding is integrally machined
Technology cost is again higher, therefore necessary to prior art progress substantial improvements and innovation, introduces full assembling, holotype
The theory of steel, on the basis of the anti-buckling support performance of all steel is ensured, replaced welding welding technique with full mounting technology, use shaped steel
Combination inner core replaces traditional yi word pattern or cross inner core, curvature-prevention support component processing is more facilitated, cost is more cheap.
The content of the invention

Including constraint cover plate at the top of core space, the both sides that cover plate lower plane is constrained at the top of core space are respectively equipped with one piece of core space edge of a wing about
Beam filler strip, core space constraint angle steel is respectively provided with core space Restraint of flange filler strip lower plane, is constrained in two core spaces under angle steel
Clamping core space web constraint filler strip, the front and back ends that cover plate is constrained at the top of core space are set at the top of transition region respectively on the inside of portion
Cover plate is constrained, the lower section both sides that cover plate is constrained at the top of transition region are respectively provided with transition region constraint angle steel；The T-shaped anti-buckling support of assembled
The inner core double angle clamping yi word pattern steel plate of inner core is placed in anti-buckling outsourcing confining part, constraint cover plate, core at the top of core space
The limb back of the body of heart district Restraint of flange filler strip and core space constraint angle steel is bolted, the acropodium of two core spaces constraint angle steel and
Core space web constraint filler strip therebetween is bolted, the acropodium of two transition regions constraint angle steel and yi word pattern steel plate and interior
Core double angle is bolted；The limb back of the body and yi word pattern steel plate and inner core double angle and transition region of two transition region constraint angle steel
Top constraint cover plate is bolted.
Advantages of the present invention is embodied in：1st, the present invention is using full assembled, i.e., no-welding-seam on curvature-prevention support component,
Avoid welding residual stress and residual deformation to the adverse effect of support performance while, be also convenient for transporting；2nd, it is of the invention
Anti-buckling support inner core and confining part be the section bar such as common angle steel and the steel plate of regular shape, be easy to buy, and only
Simple cutting processing is needed, without welding and machining, processing technology is simple, and stable performance is cheap；3rd, the present invention is all steel
The anti-buckling support of type, wet trade is avoided, production and construction is easy, production cost is relatively low, with short production cycle, stable performance.
