Description
Technical field
The present invention relates to a kind of all steel curvature-prevention support component, specifically, be a kind of T-shaped assembled anti-buckling support structure
Part, is mainly used in construction of structures to dissipate seismic energy and significantly improving the uniaxial force component of structural seismic performance.
Background technology
Owing to the anti-buckling support of all steel type has from heavy and light, the outstanding advantages such as processing is easy, obtain a large amount of in engineering
Application, wherein use yi word patterns and cross section shaped steel as inner core more.Cut owing to not producing cross inner core on market
Face, it is therefore desirable to use three block plates to be welded, the core space of yi word pattern cross section inner core and the variable cross-section of transition region are the most also
Needing to be completed by welding, this processing method has the disadvantage in that
(1) initial geometrical defect of inner core
Cross inner core can produce four weld seams in the course of processing, in the produced a large amount of high-temperature hot stress of welding are easily caused
Core produces bigger welding residual deformation, and this residual deformation can cause bracing members inner core to be difficult to insert steel duct, especially
When bearing length is longer, the assembling to supporting brings technical difficulty.Additionally, this welding residual deformation also can reduce steel
Moulding, also the stability supported can be adversely affected；
(2) actual performance and the discordance of design performance
The design surrender axle that the actual measurement surrender axle force rate of cross inner core all steel curvature-prevention support component obtains according to material test
Li Gaoyue 40%, analyzes and shows that this result is primarily due to the existence of section of weld joint area and actual inner core area of section is increased
Adding, the yield stress of weld seam is typically high than core yield strength simultaneously, thus causes the inconsistent of measured performance and design performance
Property.The deviation of this actual performance may result in anti-buckling support can not in the earthquake intensity that designer is estimated just
There is surrender power consumption, and then affect the actual anti-seismic performance of structure；
(3) adverse effect welded
Cross and yi word pattern inner core curvature-prevention support component the inner core of existing various constraint type uses welding to be connected
Structure, its low cycle fatigue property can be had a negative impact thus cause the moulding energy dissipation capacity of inner core to play and do not fill by inner core welding
Point, low-cycle fatigue fracture is occurred to early.The inner core using welding processing to make is lower than the low cycle fatigue property of welding inner core,
It addition, the welding of trocar sheath and while strengthening being welded on and bury hidden danger of quality of district, too increase difficulty of construction and make work
Phase；
Due to the cross of existing employing solder technology and yi word pattern innercore construction all can to the assembling of supporting member, stability,
Mechanical property and low cycle fatigue property have a negative impact, and the inner core one Machining Technology used in order to avoid welding
Cost is the highest, the most necessary substantial improvements and innovation of carrying out prior art, introduces full assembling, holotype steel
Theory, on the basis of ensureing the anti-buckling support performance of all steel, replaces welding solder technology with full mounting technology, uses shaped steel combination
Inner core replaces tradition yi word pattern or cross inner core, makes curvature-prevention support component processing convenient, and cost is the cheapest.
Summary of the invention
The present invention is to solve that in the support of existing concrete filled steel tube constraining anti-buckling, the cast-in-place of concrete was constructed with vibrating
Journey easily causes the displacement of special soft material plate and the local damage of non-cohesive material and the problem of production cycle length, solves simultaneously
The anti-buckling support of existing all steel is owing to welding the processing cost height caused and cannot guarantee that it has reliable low cycle fatigue property
Etc. problem, it is proposed that a kind of T-shaped assembled curvature-prevention support component.
The technical solution adopted for the present invention to solve the technical problems is: a kind of T-shaped assembled curvature-prevention support component, its
