Description
Technical field
The present invention relates to the anti-buckling support of a kind of all steel lattice, belong to technical field of structural engineering.
Background technology
Since Japanese Osaka-Kobe earthquake and U.S.'s north ridge earthquake, curvature-prevention support component, with its outstanding energy-dissipating and shock-absorbing performance, is applied gradually, and is obtained great popularization in some developed countries in some heavy construction structures.Traditional curvature-prevention support component is made up of inner core component and peripheral constraint component two parts, and under little shake effect, the inner core component of curvature-prevention support component keeps elasticity, and the lateral resistant member as agent structure uses; Under middle shake and large shake effect, the inner core component rate of anti-buckling support is introduced into surrender, plays the effect of protection main body frame, consumes a large amount of inputting seismic energies simultaneously, have very full hysteresis loop.Have " support " and " power consumption " two function of aspect concurrently just because of it, make it as one of best energy-dissipating and shock-absorbing component, by the middle of the high building structure that widely uses gradually with China.
The peripheral constraint component of curvature-prevention support component generally can be divided into following three classes: steel concrete restraining tube, steel concrete combination restraining tube and all steel restraining tube.Its inner core component then generally adopts the steel of low-yield, high ductility, and by inner core component surface mount vulcanie, to prevent the hard component damage contacting generation in curvature-prevention support component loading process between kernel with peripheral constraint component.In the design process of anti-buckling support, certain gap can be left between peripheral constraint component and inner core component, to prevent from being filled in during inner core component pressurized generation lateral expansion extremely.
Tradition curvature-prevention support component generally adopts steel concrete restraining tube, and adopt global sections form, there is following shortcoming: (1) pouring concrete and strength developing required time longer, and there is the trouble of wet trade, be difficult to form High-efficient Production and intense industrialization; (2) concrete placement precision is lower, is difficult to the required precision meeting anti-buckling support manufacture process, therefore can increases extra cost in precision controlling process; (3) large-tonnage curvature-prevention support component is according to the cross section of integral form, and section area must be caused excessive, and cause waste of material, cost of manufacture promotes greatly; (4) peripheral member adopts the large-tonnage curvature-prevention support component of steel concrete from great, will produce the difficulty in transport after entire plant machine-shaping.
Summary of the invention
The anti-buckling support of all steel lattice proposed by the invention adopts all steel component, avoids the inconvenience that concrete wet trade brings, is more convenient to carry out intense industrialization production; Connecting overhanging section of two inner core components by connecting floor, avoiding the situation that the hinged anti-buckling supporting base end portion of tradition is easy to occur local failure; Adopt a point limb formula cross section, the interior nuclear cross section of curvature-prevention support component is launched more, and bending rigidity promotes greatly, more saves material, remarkable in economical benefits in the design of the anti-buckling support of large-tonnage.
The anti-buckling support of a kind of all steel lattice, it is characterized in that, described anti-buckling support forms by with lower component: two in-line kernel steel plate, two confining parts, batten plate, vulcanie, connection floors.
Described curvature-prevention support component is made up of two points of limbs, and described point of limb comprises a confining part and parcel in-line kernel steel plate therein; Described in-line kernel steel plate totally two, pastes vulcanie in the region surface of its restrained component parcel.
Described confining part totally two, measure-alike, its length is less than the length of in-line kernel steel plate; Described confining part adopts four pieces of plate welding compositions, and wherein two pieces of flat boards are longer, form overhanging section of confining part plate.
Described batten plate is rectangle plain plate, is equidistantly arranged between two points of limbs along anti-buckling bearing length direction, forms axis bilateral symmetry arrange in pairs at two points of limbs; Batten plate and the confining part of both sides overhanging section of plate adopts three leg fillet welds to be connected.
Described connection floor is rectangle plain plate, and its length is equal with the overhanging certain distance of two in-line kernel steel plate; Connecting floor adopts twin fillet wolt to be connected with overhanging section of kernel one word steel plate; Connect between floor and confining part and there is certain spacing, spacing size is determined according to connecting floor deformation limit value under axial pressure effect.
Described connection floor is connected with structural framing with hinged or the form that just connect; Describedly being articulated and connected, by opening single pin hole on connection floor, and being realized by pinned connection with the otic placode be fixed on described structural framing; Describedly just to connect in succession, by opening bolt hole on connection floor, and to be connected by high-strength bolt with the cover plate be fixed on described structural framing and to realize.
The present invention proposes a kind of novel anti-buckling support of all steel lattice, have the following advantages:
(1) adopt a point limb formula cross section, the interior nuclear cross section of curvature-prevention support component is launched more, and bending rigidity promotes greatly, more saves material, remarkable in economical benefits in the design of the anti-buckling support of large-tonnage;
(2) adopt all steel component, adopt between its parts and be welded to connect, can be shaping at entire plant, not only avoid the inconvenience that concrete wet trade brings, be more convenient to carry out intense industrialization production;
(3) connecting overhanging section of two inner core components by connecting floor, adding the bending rigidity of overhanging section of kernel, avoid the situation that the hinged anti-buckling supporting base end portion of tradition is easy to occur local failure.
