Abstract
The invention relates to a tubular double-plate self-resetting prestressing anti-buckling support for an assembled steel structure. The tubular double-plate self-resetting prestressing anti-buckling support is formed by an inside energy consumption inner core, a peripheral steel tube restrained member and prestressing cables. The prestressing cables are arranged on the two sides of the energy consumption inner core symmetrically and penetrate through transverse ribbed stiffeners. The inside energy consumption inner core is inserted into middle interspace of the peripheral steel tube restrained member. The inside energy consumption inner core is D longer than the peripheral steel tube restrained member in order to enable the inside energy consumption inner core to perform axial deformation energy consumption. Two ends of the tubular double-plate self-resetting prestressing anti-buckling support for the assembled steel structure are completely identical in the structure. The bottom of the peripheral steel tube restrained member is welded with lower connection plates. The tubular double-plate self-resetting prestressing anti-buckling support for the assembled steel structure can perform assembly quickly and resist to horizontal sideway effectively and is applied to a construction period. By means of the tubular double-plate self-resetting prestressing anti-buckling support for the assembled steel structure, industrialization of manufacture of steel structure members can be achieved effectively, construction speed is quickened, and the amount steel is decreased greatly.
Description
Technical field
The present invention relates to a kind of novel braced structures form, particularly the anti-buckling support of tubular pair of plate assembling type steel structure Self-resetting prestressing force of one 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, Chinese scholars is also little to the research of the anti-buckling support of assembling type steel structure Self-resetting prestressing force, does not really realize quick, the integrated production of industrialization of the anti-buckling support of steel work Self-resetting prestressing force, 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 tubular pair of plate assembling type steel structure Self-resetting prestressing force anti-buckling 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:
The anti-buckling support of tubular pair of plate assembling type steel structure Self-resetting prestressing force comprises inner dual panel-type energy consumption inner core, peripheral steel tube confinement member two parts.
It is characterized in that: described inner dual panel-type energy consumption inner core is two two plate shape strip steel plates arranged side by side.For making energy consumption inner core be easy to enter plasticity power consumption, weaken inner core plates middle part, be circular arc.Dual panel-type energy consumption inner core one end is connected with a vertical square connecting plate with it, is welded to connect.Spring housing is on support column, and the two ends of support column are connected with square connecting plate and lower connecting plate respectively.The alignment of three's kernel of section welds together.Upper junction plate, with bolt hole, is linked together by high-strength bolt and framework; There is yi word pattern cavity lower connecting plate plate face center, and empty area size is identical with dual panel-type energy consumption inner core.Energy consumption inner core other end structure holds full form same therewith.
Prestressed cable two ends are connected with the two ends lower connecting plate of inner two plate shape energy consumption inner core, are connected.Tie point is positioned at two adjacent short stiffener district centers of a lattice.
Described peripheral steel tube confinement member is square steel pipe (or round steel pipe), and bottom and lower connecting plate weld together.Steel duct is welded with four angle steel steel diaphragms, leaves dual panel-type cavity in the middle of four dividing plates, and cavity size is identical with dual panel-type energy consumption inner core cross section.Clapboard spacing is by calculative determination.
In factory by described inner dual panel-type energy consumption inner core, peripheral steel tube confinement member two parts assembly and connection together.At the scene the anti-buckling support of described I shape assembling type steel structure Self-resetting prestressing force is connected with framework with high-strength bolt.When horizontal force action is during in structure, the horizontal force component of the anti-buckling support of described tubular pair of plate assembling type steel structure Self-resetting prestressing force 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.
Beneficial effect
The present invention adopts the construction stage can realize quick assembled type the effectively anti-buckling support of tubular pair of plate assembling type steel structure Self-resetting prestressing force of the horizontal sidesway of opposing.This component form not only can effectively be realized the industrialization of steel structure member processing and can greatly improve speed of application and significantly reduce steel using amount.
