Description
Technical field
The present invention relates to a kind of new structure system, particularly a kind of industrialization assembling type steel structure eccentrical braces of building field application.
Background technology
The construction of common steel work is used welding at the scene in a large number, not only affecting speed of application but also construction quality is also difficult to control, the qualitative problems of construction causing due to Construction of Steel Structure quality occurring recent years is too numerous to enumerate, Site Welding is one of them important factor, Site Welding quality is wayward, and environment is caused to very large pollution.
Traditional reinforced concrete structure needs on-the-spot assembling reinforcement, fluid concrete, needs a large amount of artificial and curing times, and construction costs improves greatly.And when building demolition, cause a large amount of building wastes.
Recent years, domestic scholars only limits to multilayer to the research of assembling type steel structure, and just slightly minimizing of speed of application, does not really realize the Fast Installation of steel work, embodies the advantage of steel work.
Prestress steel member is only used in a beam string structure at present, also in high-level structure, does not use, and adopts prestress steel member in engineering, also not have realization as high-rise lateral resisting structure.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.The problems such as to be supported on the permanent set producing under severe earthquake action still irrecoverable but tradition is anti-buckling, and traditional anti-buckling support also has concrete peripheral constraint component, and the machining accuracy control difficulty, the wet trade workload that cause are large.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect of existing engineering, a kind of structural system of many, high-rise steel structure rapid construction is provided, this structural system can realization body steel work and the Fast Installation of Self-resetting prestressing force supporting member, and can resist high-intensity earthquake, ideally embody the advantage of steel work.
In order to achieve the above object, the present invention adopts following technical scheme:
Industrialization assembling is many, the anti-buckling eccentrical braces of high-rise steel structure framework veneer Self-resetting prestressing force comprises steel work main body grillage, Self-resetting prestressing force supporting member, pillar system, it is characterized in that: described steel work main body grillage comprises basic grillage, floor.In factory, described wide beam, narrow beam, floor are made of one, wide beam and narrow beam are in factory and are welded by framework veneer.Pipeline passes through between the web framework veneer of wide beam and narrow beam, thereby forms A basis grillage, B basis grillage and C basis grillage.At described foundation slab frame plate and described column base connecting portion, described wide beam and described narrow beam junction are with bolts and part welding (only limiting in factory).Between described column base and described pillar, adopt bolt to be connected by flange.
Described Self-resetting prestressing force supporting member can be spring, and logical being enclosed within on support column of described spring is connected with junction plate; Also have prestressed cable or prestressing force steel pole and be connected otic placode, described otic placode is connected with described mainboard by high-strength bolt.When horizontal force action is during in structure, described Self-resetting prestressing force supporting member horizontal force component 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.Spring mainly acts in the time of pressurized, and presstressed reinforcing steel works in the time of tension.
Beneficial effect
The present invention adopts the construction stage can realize quick assembled type the effective high-rise steel structure Self-resetting prestressing force 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.And supporting member has very strong bearing capacity under little shake, by improving its initial pressurized, drawing bearing capacity, reduce even to eliminate its permanent set under large shake, there is very strong energy dissipation capacity.
Find by engineering practice and the experiment of 1:10 vibroplatform, described new structure system has improved 500% than ordinary construction system speed of application, and steel using amount reduce by 50%, and realize job site " anhydrous, without fire, dustless ", the potential safety hazard that has reduced site operation, reduces environment pollution.
