Description

Industrialization assembled is many, high-rise steel structure tubular pair of plate self reset curvature-prevention timbering with rafter arch sets's system

Technical field

The present invention relates to a kind of new structural systen, particularly a kind of industrialization assembling type steel structure timbering with rafter arch sets's system of building field application.

Background technology

The construction of common steel construction uses welding in a large number at scene, 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 environment causes very big pollution.

Traditional skeleton construction needs on-the-spot assembling reinforcement, deposit concrete, it is necessary to 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 assembling type steel structure is only limitted to multilayer by domestic scholars, and speed of application just slightly reduces, and does not really realize the Fast Installation of steel construction, embodies the advantage of steel construction.

Curvature-prevention support component is as the lateral resisting energy-dissipating device being applied in Rotating fields many, high; under middle shake or big shake effect; curvature-prevention support component all can realize entirety or the local buckling failure that total cross section is fully surrendered and bracing member do not occur when drawing, press; make originally to be changed into by the power consumption mode of agent structure beam-ends plastic hinge on anti-buckling support component, only concentrate power consumption, thus protect agent structure preferably. But the residual set that tradition is anti-buckling to be supported under severe earthquake action to produce is still irrecoverable, and traditional anti-buckling support also has the problems such as working accuracy control difficulty that concrete peripheral constraint component (2-3) causes, wet trade workload are big.

Summary of the invention

It is an object of the invention to overcome the above-mentioned defect of existing engineering, the structural system of a kind of many, high-rise steel structure rapid construction is provided, this structural system can realization body steel construction and the Fast Installation from reset bracing member, and high-intensity earthquake can be resisted, embody the advantage of steel construction perfectly.

In order to achieve the above object, the present invention adopts following technical scheme:

Industrialization assembled is many, high-rise steel structure tubular pair of plate self reset curvature-prevention timbering with rafter arch sets's system comprises steel construction main body grillage, reset bracing member, pillar system certainly, it is characterised in that: described steel construction main body grillage comprises basis grillage, floor. Described wide beam, narrow beam, floor being 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 basis grillage plate with described column base connecting portion, described wide beam is with bolts with described narrow beam junction and partly welds (being only limitted in factory). Bolt is adopted to pass through Flange joint between described column base and described pillar.

Described can be spring from reset bracing member, and the logical cover of described spring is connected with web plate on the support columns. When horizontal force action is in structure, described reduce even to offset from reset bracing member horizontal force component act on the horizontal force of structure, make displacement between the layer of structure be smaller value, meet the requirement of specification.

Useful effect

The present invention adopts high-rise steel structure that the construction stage can realize quick assembled type and can effectively resist horizontal comparison from resetting support system. This kind of structure formation can not only effectively 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 reduces by 50%, and realize working-yard " anhydrous, without fire, without dirt ", reduce the potential safety hazard of site operation, reduce environmental pollution.
