Description
Technical field
The present invention relates to a kind of building energy-dissipating and shock-absorbing constraint steel supporting component, be specifically related to the buckling-restrained steel supporting component of a kind of large supporting capacity.
Background technology
Buckling restrained brace is by conventional steel brace being taked the constraint measure, and by central layer, non-cohesive material forms in outer sleeve and the sleeve, and it can avoid central layer pressurized flexing fully, is the very high structural element of efficient; Simultaneously buckling restrained brace all surrenders under pressure and pulling force effect, and hysteresis loop is full, is the energy dissipative device of superior performance.
Buckling restrained brace central layer form can be divided into two large types at present: the first type is open cross-sections, for example " one ", " ten " or " H " type, the second type is the closed type cross section, for example round steel pipe, square steel pipe.The open cross-sections central layer is easy to make, and can adopt plain plate to weld splicing, and the closed type cross section will be made into pipe or square tube with plain plate by task equipment, makes to require height.What application was maximum at present is that central layer is the buckling restrained brace of open type.Yet open type buckling restrained brace commonly used exists problem separately.Because thickness of slab restriction, " one " font and " ten " font buckling restrained brace are mainly used in the buckling restrained brace of less bearing capacity, this is because " one " font and " ten " font second moment of area are less, and because thickness of slab restriction, as increasing supporting capacity, need the enlarging section size, thereby can have influence on building function.The buckling restrained brace in " H " type cross section has larger supporting capacity, and than " one " font and " ten " font cross section, " H " type second moment of area is larger." yet H " core plate moment of inertia on two major axes orientations differs greatly, and needs the larger outer addition of constraints sleeve of rigidity on weak direction of principal axis.Thereby invent a kind of " king " font central layer section form, and increase stressed section area, only increase simultaneously the moment of inertia on the weak direction of principal axis.This " king " font central layer cross section is compared with " H " shape, on the less situation of strong direction of principal axis moment of inertia impact, has increased weak axial moment of inertia, can increase the section area of central layer again simultaneously, thereby improve the bearing capacity of buckling restrained brace." king " font central layer cross section buckling restrained brace will be the technology of a kind of economy and superior performance, and it can reduce the constraint rigidity of outer sleeve, thereby reduces buckling-restrained apparent size.
The constraint type that buckling restrained brace is commonly used is steel concrete, Steel-Concrete Composite Sections and steel tube confinement form.The present invention increases the constraint plate at steel tube confinement in form, and whole constraint rigidity both is provided, and retrains again the cripling on the edge of a wing.
Summary of the invention
The present invention be to provide a kind of and be easy to make, supporting capacity is large, " king " font cross section large bearing capacity buckling-restrained bracing member of saving steel, it is too little to be used for solving " one " font " ten " font buckling-restrained bracing member bearing capacity, and H type cross section buckling-restrained bracing member both direction retrains the inconsistent problem of rigidity requirement, also can reduce the outward appearance cross-sectional sizes of buckling restrained brace.
For achieving the above object, technical scheme of the present invention is: a kind of " king " font cross section large bearing capacity buckling-restrained bracing member, comprise the central layer web, the central layer top flange, the edge of a wing in the central layer, the central layer bottom flange, end web stiffener, top flange, end stiffener, edge of a wing stiffener in the end, bottom flange, end stiffener, the sleeve top board, the cover tube end plate, stretch plate in first to fourth sleeve, the outer vertical plate of sleeve, stiffener in the sleeve, without the bonding spacer material layer, be characterized in: central layer web and central layer top flange, the edge of a wing is by being welded to form " king " font section structural member in central layer bottom flange and the central layer, be welded with respectively end web stiffener in the middle of " king " font section structural member two ends, be positioned at the central layer top flange of web stiffener both sides, end, the edge of a wing and central layer bottom flange front end are welded with respectively top flange, end stiffener in the central layer, edge of a wing stiffener and bottom flange, end stiffener in the end, be respectively equipped with sleeve top board and cover tube end plate on the upper surface, central layer top flange and the lower surface, central layer bottom flange, lower surface, central layer top flange, in the central layer on the edge of a wing, lower surface and upper surface, central layer bottom flange are respectively equipped with in first to fourth sleeve stretches plate, stretch in the first sleeve to stretch between the plate in plate and the second sleeve and stretch in the 3rd sleeve to stretch between the plate in plate and the quadruplet cylinder and be respectively equipped with stiffener in several sleeves along central layer web length direction, two outsides are respectively equipped with the outer vertical plate of sleeve, and stretch plate and sleeve top board in the outer vertical plate of sleeve and first to fourth sleeve, the cover tube end plate is by being welded to connect into the integral sleeve of " king " font section structural member.
The area surfaces of wrapping up between the integral sleeve of " king " font section structural member and " king " font section structural member is pasted without the bonding spacer material layer.
Stretching the clear distance of stretching in plate and the 3rd sleeve between the plate in the second sleeve is central layer wing centre section edge thickness and two times of nothing bonding isolated material layer thickness sums; The distance of stretching in the first sleeve between plate and the sleeve top board is central layer top flange thickness and two times of nothing bonding isolated material layer thickness sums; The distance of stretching in the quadruplet cylinder between plate and the cover tube end plate is central layer bottom flange thickness and two times of nothing bonding isolated material layer thickness sums; Stretching plate in first to fourth sleeve is one times of nothing bonding isolated material layer thickness apart from central layer web clear distance.
Sleeve top board and sleeve bottom end are respectively equipped with in advance cracks, be used for end web stiffener and pass respectively sleeve top board and cover tube end plate, the cracking length of sleeve top board and cover tube end plate is greater than the deformation length of end web stiffener in the axial tension deformation process; Crack in advance in the centre of top flange, end stiffener and bottom flange, end stiffener and web stiffener intersection location place, end, stitch wide should than the large 2mm-3mm of end web stiffener thickness, being convenient to end web stiffener and passing top flange stiffener and bottom flange, end stiffener.
