Description
Technical field
The present invention relates to a kind of new structural systen, a kind of industrialization assembling type steel structure timbering with rafter arch sets system of particularly building field application.
Background technology
The construction of common steel work uses welding at the scene in a large number, not only affect speed of application but also construction quality also very difficult control, the qualitative problems of construction caused due to Construction of Steel Structure quality occurred recent years is too numerous to enumerate, Site Welding is one of them important factor, Site Welding quality is wayward, and causes very large pollution to environment.
Traditional reinforced concrete structure needs on-the-spot assembling reinforcement, fluid concrete, and need a large amount of artificial and curing times, construction costs improves greatly.And cause a large amount of building wastes during building demolition.
Recent years, the research of domestic scholars to assembling type steel structure is only limitted to multilayer, and speed of application just slightly reduces, and does not really realize the Fast Installation of steel work, embodies the advantage of steel work.
Curvature-prevention support component is as the lateral resisting energy-dissipating device be applied in many, high-level structure; under middle shake or large shake effect; curvature-prevention support component all can realize total cross-section drawing, when pressing and fully surrenders and do not occur that the entirety of supporting member or cripling are destroyed; make originally to be changed into by the power consumption mode of agent structure beam-ends plastic hinge only on anti-buckling support component, to concentrate power consumption, thus protect agent structure preferably.But tradition is anti-buckling be supported on severe earthquake action under the permanent set that produces still irrecoverable, and traditional anti-buckling support also has machining accuracy that concrete peripheral constraint component (2-3) causes controls the problems such as difficulty, wet trade workload are large.
Summary of the invention
The object of the invention is to the above-mentioned defect overcoming existing engineering, a kind of structural system of many, high-rise steel structure rapid construction is provided, this structural system can the Fast Installation of realization body steel work and Self-resetting supporting member, and can high-intensity earthquake be resisted, 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, high-rise steel structure tubular veneer self reset curvature-prevention timbering with rafter arch sets system comprises steel work main body grillage, Self-resetting supporting member, pillar system, it is characterized in that: described steel work main body grillage comprises basic grillage, floor.Described wide beam, narrow beam, floor are made of one in factory, wide beam and narrow beam are and are welded by tubular veneer in factory.Pipeline passes through between the tubular veneer of web of wide beam and narrow beam, thus 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 part with bolts with described narrow beam junction is welded (being only limitted in factory).Bolt is adopted to pass through Flange joint between described column base and described pillar.
Described Self-resetting supporting member can be spring, and the logical cover of described spring is connected with junction plate on the support columns.When horizontal force action is in structure, described Self-resetting supporting member horizontal force component reduces even negative function in the horizontal force of structure, and the relative storey displacement making structure is smaller value, meets the requirement of specification.
Beneficial effect
The present invention adopts the construction stage can realize quick assembled type and effectively can resist the high-rise steel structure Self-resetting support system of horizontal comparison.This form of structure effectively can not only realize the industrialization of steel structure member processing and greatly can improve speed of application and significantly reduce steel using amount.
Found by engineering practice and 1:10 vibrostand experiment, described new structural systen improves 500% than ordinary construction system speed of application, and steel using amount reduce by 50%, and realize job site " anhydrous, without fire, dustless ", reduce the potential safety hazard of site operation, reduce environment pollution.
