Abstract
A cross steel angle assembly type steel structure self-resetting buckling-restrained brace comprises an internal cross energy dissipation inner core, peripheral steel pipe restriction components and springs. An internal cross energy dissipation inner core plate is a cross biplate steel plate. Two straight steel plates are welded together in a perpendicular mode to form a cross biplate steel angle. The middle of a chip board is weakened to form a circular arc shape. One end of the energy dissipation inner core is provided with two connecting plates which are perpendicular to the energy dissipation inner core, namely, the upper connecting plate and the lower connecting plate are connected with the energy dissipation inner core in a perpendicular welding mode. The outermost connecting plate of the end of a supporting component is provided with bolt holes to connect a high-strength bolt together with a frame. The upper connecting plate and the lower connecting plate are welded and connected together through short stiffening ribs. The short stiffening ribs are perpendicular to the two plates. When horizontal force acts on a structure, the horizontal force component of the cross steel angle assembly type steel structure self-resetting buckling-restrained brace reduces and even offsets the horizontal force acting on the structure, story drift of the structure is made to be small, and requirements of specifications are met.
Description
Technical field
The present invention relates to a kind of novel braced structures form, particularly the cross angle steel assembling type steel structure of the one self reset curvature-prevention of building field application supports.
Background technology
Tradition supports because its rigidity is large, and under severe earthquake action, tensile stress conventionally exceedes elastic limit and surrenders, and produces expendable permanent set; When pressurized, easily be there is lateral deflection song.Under earthquake repeated action, its energy consumption effect is little, is also difficult to protect preferably agent structure not to be damaged.
Curvature-prevention support component is many as being applied to, lateral resisting energy-dissipating device in high-level structure; under middle shake or large shake effect; curvature-prevention support component all can be realized total cross-section and fully surrenders and do not occur that the entirety of supporting member or cripling destroy in the time drawing, press; make originally to change into and only on anti-buckling support component, concentrate power consumption by the power consumption mode of agent structure beam-ends plastic hinge, thereby protected preferably agent structure.But tradition is anti-buckling, to be supported on the permanent set producing under severe earthquake action still irrecoverable, and traditional anti-buckling support also has the problems such as machining accuracy control difficulty, wet trade workload that concrete peripheral constraint component causes are large.
Recent years, the research that Chinese scholars supports assembling type steel structure self reset curvature-prevention is also little, does not really realize quick, the integrated production of industrialization that steel work self reset curvature-prevention supports, and embodies the advantage of steel work.
Summary of the invention
The object of the invention is to overcome existing above-mentioned defect, provide a kind of novel cross angle steel assembling type steel structure self reset curvature-prevention to support, this invention can realization body steel work and supporting member fast, reasonable installation.And under little shake, there is very strong bearing capacity, pass through to improve its initial tensile capacity, reduce even to eliminate its permanent set under large shake, there is very strong energy dissipation capacity.
In order to achieve the above object, the present invention adopts following technical scheme:
Cross angle steel assembling type steel structure self reset curvature-prevention supports and comprises inner cross energy-consumption inner core, peripheral steel tube confinement member, spring three parts.
It is characterized in that: described inner cross energy-consumption inner core plates is cross biplate steel plate.Two yi word pattern steel plates are intersected vertically and welded together, form cross biplate angle steel; For making energy consumption inner core be easy to enter plasticity power consumption, weaken chip board middle part, be circular arc.Energy consumption inner core one end is two vertical junction plates with it: upper junction plate, lower connecting plate are connected with energy consumption inner core vertical welding.Supporting member end outermost junction plate, with bolt hole, links together high-strength bolt and framework.Upper junction plate, lower connecting plate are welded together by short stiffener.Short stiffener is all vertical with two plates.
Described peripheral angle steel confining part is four angle steel, and four angle steel are lined up cross, and the limb back of the body facing each other connects with bolt, between relative limb, connects with bolt.Each bolt sleeve has sleeve pipe, and casing length is identical with energy consumption inner core thickness.Sleeve is positioned between the bolted two limb back ofs the body.Between two limbs of each angle steel, be all connected with transverse stiffener.One section of square steel pipe is respectively inserted at angle steel two ends, and square steel pipe one end adds two fixed heads, and with fixed support post, by spring housing, on support column, cross inner energy consumption inner core is inserted in the intermediate gaps of peripheral angle steel confining part.
In factory by described inner cross energy-consumption inner core, peripheral steel tube confinement member two parts assembly and connection together.At the scene described I shape assembling type steel structure self reset curvature-prevention support is connected with framework with high-strength bolt.When horizontal force action is during in structure, the horizontal force component that described cross angle steel assembling type steel structure self reset curvature-prevention supports reduces even negative function in the horizontal force of structure, and making the relative storey displacement of structure is smaller value, meets the requirement of specification.
Beneficial effect
The present invention adopts the construction stage can realize quick assembled type the effective high-rise steel structure Self-resetting support system of the horizontal sidesway of opposing.This form of structure not only can effectively realize the industrialization of steel structure member processing and can greatly improve speed of application and significantly reduce steel using amount.
