Description
Technical field
The present invention relates to a kind of novel braced structures form, the particularly two anti-buckling supports of plate Self-resetting prestressing force of a kind of assembling type steel structure framework of building field application.
Background technology
Tradition supports because its rigidity is large, and under severe earthquake action, tensile stress conventionally surpasses elastic limit and surrenders, and produces expendable permanent set; During 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, the 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 integral body of supporting member or cripling destroy when drawing, pressing; the original power consumption mode by agent structure beam-ends plastic hinge is changed into and only on anti-buckling support component, concentrate power consumption, 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 machining accuracy that concrete peripheral constraint component causes and controls the problems such as difficulty, wet trade workload are large.
Recent years, Chinese scholars to the research of the anti-buckling support of assembling type steel structure Self-resetting prestressing force also seldom, does not really realize quick, the integrated production of industrialization of the anti-buckling support of steel work Self-resetting prestressing force.
Summary of the invention
The object of the invention is to overcome existing above-mentioned defect, provide a kind of novel fabricated steel structure frame two anti-buckling supports of plate Self-resetting prestressing force, 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 compression bearing, 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 two anti-buckling supports of plate Self-resetting prestressing force of assembling type steel structure framework comprise inner power consumption chip, peripheral frame confining part, prestressed cable three parts.It is characterized in that: described inner power consumption chip is two yi word pattern steel plates side by side.For the chip that makes to consume energy is easy to enter plasticity power consumption, weaken chip board middle part, be circular arc.Power consumption chip one end is two vertical junction plates with it: power consumption chip upper junction plate, power consumption chip lower connecting plate.Topmost a junction plate, with bolt hole, is linked together by high-strength bolt and framework.Above and below two junction plates are linked together by double short stiffener.Short stiffener is all vertical with two plates.The power consumption chip other end directly and peripheral frame confining part bottom connecting plate weld together.
Described peripheral frame confining part is upper and lower two frange plates, centre is the monolithic steel diaphragm along elongated direction, middle two ends are double transverse stiffener, all weld together with upper and lower two frange plates, leave respectively the width of a power consumption chip between double transverse stiffener and steel diaphragm.Peripheral frame confining part is arranged transverse stiffener along total length from upper end.The spacing of transverse stiffener is by calculative determination.Spring housing is on support column, and the two ends of support column are connected with the junction plate at two ends respectively.Spring only works when being squeezed plate extruding.Peripheral frame confining part bottom connecting plate is connected with short stiffener with adjacent lateral stiffening intercostal.
Prestressed cable two ends are connected with the lower connecting plate of inside power consumption chip, and two ends are arranged symmetrically with.Tie point is positioned at two adjacent short stiffener district centers of a lattice.
In factory by described inner power consumption chip, peripheral frame confining part, prestressed cable three part assembly and connections together.At the scene the two anti-buckling supports of plate Self-resetting prestressing force of described assembling type steel structure framework are connected with framework with high-strength bolt.When horizontal force action is during in structure, the horizontal force component of the two anti-buckling supports of plate Self-resetting prestressing force of described assembling type steel structure framework 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 standard.
Beneficial effect
The present invention adopts the construction stage can realize quick assembled type the effectively two anti-buckling supports of plate Self-resetting prestressing force of assembling type steel structure framework 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.
