Abstract
The invention discloses an I-shaped double-board self-restoration anti-buckling support of a fabricated steel structure and belongs to the technical field of building construction. The I-shaped double-board self-restoration anti-buckling support of the fabricated steel structure comprises an internal energy-consumption inner core, a peripheral frame type restraint component and springs, wherein the internal energy-consumption inner core is a linear double-piece steel plate and is in the shape of a circular arc. Spring squeezing plates are symmetrically arranged certain distances away from the ends of the inner core and used for squeezing the springs on supporting pillars. Each end of the internal energy-consumption inner core is connected with two connecting plates which are arranged side by side and are perpendicular to the end of the internal energy-consumption inner core. The connecting plates comprise the internal energy-consumption inner core upper connecting plates and the internal energy-consumption inner core lower connecting plates. The lower connecting plates are provided with bolt holes and are connected with a frame through high-strength bolts. Each upper connecting plate and the corresponding lower connecting plate are connected in a welded mode through short stiffening ribs. The short stiffening ribs are perpendicular to the upper connecting plates and the lower connecting plates. The structures of the two ends of the internal energy-consumption inner core are completely identical. When horizontal force is exerted on the structure, the component of the horizontal force of the self-restoration anti-buckling support of the fabricated steel structure can reduce or even neutralize the horizontal force exerted on the structure, as a result, the inter-story displacement of the structure is small, and standard requirements are met.
Description
Technical field
The present invention relates to a kind of novel braced structures form, the particularly two anti-buckling supports in sheet reset position of a kind of I shape 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 prestressing force, does not really realize quick, the integrated production of industrialization of the anti-buckling support of steel work prestressing force.
Summary of the invention
The object of the invention is to overcome existing above-mentioned defect, provide the two plate self reset curvature-preventions of a kind of novel fabricated steel work I shape 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 bearing 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:
The two plate assembling type steel structure self reset curvature-preventions of I shape support and comprise inner energy consumption inner core, peripheral frame confining part, spring three parts.
It is characterized in that: described inner energy consumption inner core is yi word pattern biplate steel plate.For making energy consumption inner core be easy to enter plasticity power consumption, weaken chip board middle part, be circular arc.Be arranged symmetrically with spring stripper plate apart from a distance, inner core end, be used for pushing the spring on support column.Inner energy consumption inner core end connects two vertical junction plates with it side by side: inner energy consumption inner core upper junction plate, inner energy consumption inner core lower connecting plate.Lower connecting plate, with bolt hole, is linked together by high-strength bolt and framework.Upper and lower two junction plates are welded together by short stiffener.Short stiffener is all vertical with upper and lower two junction plates.Inner energy consumption inner core two ends structure is identical.
Described peripheral frame confining part is channel-section steel, and arranges up and down two blocks of frange plates, i.e. external frame confining part top flange plate, external frame confining part bottom wing listrium; Between upper and lower frange plate, be welded with I shape web, channel-section steel outward opening, back to placement, leaves certain width between two channel-section steel webs.There is I shape web centre, is symmetrical arranged two energy consumption inner core plates between channel-section steel and web, between channel-section steel limb, arranges transverse stiffener along total length.Transverse stiffener and channel-section steel welding.The edge of a wing welding of upper bottom flange and web channel-section steel or be connected with bolt.Channel-section steel certain length in the middle of upper and lower two edges of a wing need grow, arrange junction plate at top flange and channel-section steel end, be edge of a wing end plate and channel-section steel end plate, by spring housing on support column, the two ends of support column are separately fixed between edge of a wing end plate and channel-section steel end plate, spring is located between channel-section steel end plate and spring stripper plate, spring at pressurized, draw Shi Junneng to play Self-resetting effect.In factory by described inner energy consumption inner core, peripheral frame confining part 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 I shape 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.
The present invention can obtain following beneficial effect:
The present invention adopts the construction stage can realize quick assembled type the effectively I shape assembling type steel structure self reset curvature-prevention support 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.
