Abstract
The invention belongs to the technical field of building construction and discloses a self-resetting and prestressed buckling-restrained brace of an I-shaped angle steel assembled-type steel structure. The self-resetting and prestressed buckling-restrained brace comprises an inside crossed energy-consuming inner core, peripheral steel pipe restraining components and prestressed ropes, the inside crossed energy-consuming inner core is a single plate, the middle portion of a chip plate is reduced to be circular-arc-shaped in order to enable the energy-consuming inner core to enter easily for plastic energy consuming, an upper connecting plate and a lower connecting plate which are perpendicular to the energy-consuming inner core are arranged at one end of the same and perpendicularly connected in a welded manner, a supporting component is connected with a frame, each upper connecting plate and the corresponding lower connecting plate are connected in a welded manner by short reinforcing ribs which are perpendicular to the two connecting plates, and spring extruding plates are used for restraining supporting columns and compressing springs along with drawing of the inner core plate. When a horizontal force acts on the structure, horizontal force component of the self-resetting and prestressed buckling-restrained brace is reduced or even offsets the horizontal force acting on the structure, so that interlayer displacement of the structure is enabled to be small to meet standard requirements.
Description
Technical field
The present invention relates to a kind of novel braced structures form, particularly the anti-buckling support of a kind of yi word pattern angle steel assembling type steel structure 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, 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 yi word pattern 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:
Yi word pattern angle steel assembling type steel structure self reset curvature-prevention supports and comprises inner cross energy-consumption inner core, peripheral steel tube confinement member, prestressed cable three parts.
Described inner yi word pattern energy consumption inner core plates is a veneer, for making energy consumption inner core be easy to enter plasticity power consumption, weakens chip board middle part, is circular arc; Energy consumption inner core one end is two vertical junction plates with it: upper junction plate, lower connecting plate, be connected with energy consumption inner core vertical welding.The junction plate of supporting member end, with bolt hole, is linked together by high-strength bolt and framework.Upper junction plate, lower connecting plate are welded together by short stiffener.Short stiffener is all vertical with two junction plates.Spring stripper plate is used for retraining support column, and carrys out Compress Spring with the twitch of inner core plates;
Described peripheral angle steel confining part is four angle steel, and first limb welds together back to it between two, the T font being down.Again the edge of a wing of two T fonts is bolted together.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 welded 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, inner energy consumption inner core is inserted in the intermediate gaps of peripheral angle steel confining part.Prestressed cable is arranged symmetrically in the both sides of energy consumption inner core; Through the transverse stiffener in the middle of external frame confining part (angle steel), its two ends are connected with the upper junction plate of inner energy consumption inner core fine strain of millet end respectively.
In factory by described inner yi word pattern energy consumption inner core, peripheral constraint component 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 tubular in-line plate 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 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.
