Abstract
The invention discloses a tubular crossed plate assembly type steel-structure self-resetting pre-stressed buckling restrained brace. The brace consists of an interior-crossed energy dissipation inner core, a peripheral steel tube restrained member and pre-stressed cables. The interior energy dissipation inner core is inserted into a middle gap of the peripheral steel tube restrained member. The pre-stressed cables are symmetrically arranged on two sides of the energy dissipation inner core and pass through horizontal stiffening ribs. In order to enable the interior energy dissipation inner core to be subjected to axial deformation and energy dissipation, the interior energy dissipation inner core is longer than the peripheral steel tube restrained member by a distance D. Two ends of the tubular crossed plate assembly type steel-structure self-resetting pre-stressed buckling restrained brace are structurally identical. The tubular crossed plate assembly type steel-structure self-resetting pre-stressed buckling restrained brace can be used for realizing quick assembly and can be used for effectively resisting horizontal lateral sway in a construction stage. In a member form, industrialization of steel-structure member processing can be effectively realized, the construction speed can be greatly increased, and the steel consumption is greatly reduced.
Description
Technical field
The present invention relates to a kind of novel braced structures form, particularly the tubular cross plate assembling type steel structure of the one self reset curvature-prevention of building field application supports.
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, the research that Chinese scholars supports assembling type steel structure self reset curvature-prevention is also little, does not really realize quick, the integrated production of industrialization that steel work self reset curvature-prevention supports, and 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 New pipe saltire shape 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 cross plate assembling type steel structure Self-resetting prestressing force comprises inner cross energy-consumption inner core, peripheral steel tube confinement member two parts.
It is characterized in that: described inner cross energy-consumption inner core is two vertical cross strip steel plates.For making energy consumption inner core be easy to enter plasticity power consumption, weaken inner core plates middle part, be circular arc.Cross 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 cross 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 internal cruciform 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 cross cavity in the middle of four dividing plates, and cavity size is identical with cross energy-consumption inner core cross section.Clapboard spacing is by calculative determination.
In factory by described inner cross 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 cross 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 cross 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.
