Description
Technical field
The present invention relates to a kind of new structure system, particularly a kind of industrialization assembling type steel structure of building field applicationHerringbone support system.
Background technology
The construction of common steel construction is used welding at the scene in a large number, not only affects speed of application but also construction quality also veryDifficult control, the qualitative problems of construction causing due to Construction of Steel Structure quality occurring recent years is too numerous to enumerate, and Site Welding isThe factor that one of them is important, Site Welding quality is wayward, and environment is caused to very large pollution.
Traditional reinforced concrete structure needs on-the-spot assembling reinforcement, cast concrete, needs a large amount of artificial and maintenancesTime, 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 speed of application just slightlyReduce, really do not realize the Fast Installation of steel construction, embody the advantage of steel construction.
Curvature-prevention support component is many as being applied to, lateral resisting energy-dissipating device in high-level structure, does in middle shake or large shakeWith under, curvature-prevention support component in the time drawing, press, all can realize total cross-section fully surrender and do not occur supporting member entirety or officePortion's buckling failure, makes originally only to be changed into and collected on anti-buckling support component by the power consumption mode of agent structure beam-ends plastic hingeMiddle power consumption, thus agent structure protected preferably. But the anti-buckling residual deformation producing under severe earthquake action that is supported on of traditionStill irrecoverable, and traditional anti-buckling support also has the machining accuracy control that concrete peripheral constraint component (2-3) causesThe problems such as system is difficult, wet trade workload is large.
Summary of the invention
The object of the invention is to overcome the above-mentioned defect of existing engineering, a kind of many, high-rise steel structure rapid construction is providedStructural system, this structural system can realization body steel construction and the Fast Installation of Self-resetting supporting member, and can supportAnti-high-intensity earthquake, ideally embodies the advantage of steel construction.
In order to achieve the above object, the present invention adopts following technical scheme:
Industrialization assembled is many, the tubular cross plate self reset curvature-prevention of high-rise steel structure herringbone support system comprises steelMain structure body grillage, Self-resetting supporting member, pillar system, is characterized in that: described steel construction main body grillage comprises soleplateFrame, 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 tubular veneerForm. Pipeline passes through between the tubular veneer of web of wide beam and narrow beam, thereby forms A basis grillage, B basis grillage and C basisGrillage. With bolts at described soleplate frame plate and described column base connecting portion, described wide beam and described narrow beam junctionAnd part welding (only limiting in factory). Between described column base and described pillar, adopt bolt to be connected by flange.
Described Self-resetting supporting member can be spring, and logical being enclosed within on support column of described spring is connected with connecting plate. Work as waterWhen flat masterpiece is used for structure, described Self-resetting supporting member horizontal force component reduces even negative function in the horizontal force of structure,Making the relative storey displacement of structure is smaller value, meets the requirement of specification.
Beneficial effect
The present invention adopts the construction stage can realize quick assembled type the effective Tall Steel knot of the horizontal sidesway of opposingStructure Self-resetting support system. This version not only can effectively realize steel structure member processing industrialization and also canGreatly improve speed of application and significantly reduce steel using amount.
Find by engineering practice and the experiment of 1:10 shake table, described new structure system is than ordinary construction system construction speedDegree has improved 500%, and steel using amount reduction by 50%, and realizes " anhydrous, the nothing fire, dustless " of job site, has reduced existingThe potential safety hazard of field construction, reduces environmental pollution.
