Description
Technical field
The present invention relates to a kind of novel braced structures form, particularly the anti-buckling support of a kind of assembling type steel structure framework veneer Self-resetting prestressing force of building field application.
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, Chinese scholars is also little to the research of the anti-buckling support of assembling type steel structure Self-resetting prestressing force, does not really realize quick, the integrated production of industrialization of the anti-buckling support of steel work Self-resetting prestressing force.
Summary of the invention
The object of the invention is to overcome existing above-mentioned defect, provide a kind of novel fabricated steel structure frame veneer Self-resetting prestressing force anti-buckling 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 compression bearing, 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:
The anti-buckling support of assembling type steel structure framework veneer Self-resetting prestressing force comprises inner power consumption chip, peripheral frame confining part, prestressed cable three parts.It is characterized in that: described inner power consumption chip is yi word pattern single steel plate.For the chip that makes to consume energy is easy to enter plasticity power consumption, weaken chip board middle part, be circular arc.Power consumption chip one end is two vertical junction plates with it: power consumption chip upper junction plate, power consumption chip lower connecting plate.Topmost a junction plate, with bolt hole, is linked together by high-strength bolt and framework.Above and below two junction plates are linked together by double short stiffener.Short stiffener is all vertical with two plates.The power consumption chip other end directly and peripheral frame confining part bottom connecting plate weld together.
Described peripheral frame confining part is upper and lower two frange plates, and middle double transverse stiffener welds together, and double lateral stiffening intercostal leaves the width of a power consumption chip.Peripheral frame confining part is arranged transverse stiffener along total length from upper end.The spacing of transverse stiffener is by calculative determination.Spring housing is on support column, and the two ends of support column are connected with the junction plate at two ends respectively.Spring only works in the time being squeezed plate extruding.Peripheral frame confining part bottom connecting plate is connected with short stiffener with adjacent lateral stiffening intercostal.
Prestressed cable two ends are connected with the lower connecting plate of inside power consumption chip.Tie point is positioned at two adjacent short stiffener district centers of a lattice.
In factory by described inner power consumption chip, peripheral frame confining part, prestressed cable three part assembly and connections together.At the scene the anti-buckling support of described assembling type steel structure framework veneer Self-resetting prestressing force is connected with framework with high-strength bolt.When horizontal force action is during in structure, the horizontal force component of the anti-buckling support of described assembling type steel structure framework veneer Self-resetting prestressing force 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 effectively anti-buckling support of assembling type steel structure framework veneer Self-resetting prestressing force of the horizontal sidesway of opposing.This component form not only can effectively be realized the industrialization of steel structure member processing and can greatly improve speed of application and significantly reduce steel using amount.
