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
From Japanese slope, celestially since the ridge earthquake of Zhen Yu U.S. north, curvature-prevention support component, with its outstanding energy-dissipating and shock-absorbing performance, is applied gradually, and has been obtained great popularization in some developed countries in some heavy construction structures.Traditional curvature-prevention support component is comprised 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, as the lateral resistant member of 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, has very full hysteresis loop.The function that has " support " and " power consumption " two aspects concurrently just because of it, makes it as one of best energy-dissipating and shock-absorbing member, is widely used gradually in the middle of the high building structure 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 generally adopts the steel of low-yield, high ductility, and by paste vulcanie on inner core component surface, to prevent the hard component damage producing that contacts between kernel and peripheral constraint component in curvature-prevention support component loading process.In the design process of anti-buckling support, can between peripheral constraint component and inner core component, leave certain gap, filled in when preventing inner core component pressurized generation lateral expansion dead.
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 are longer, and have the trouble of wet trade, be difficult to form High-efficient Production and intense industrialization; (2) concrete placement precision is lower, is difficult to meet the required precision of anti-buckling support manufacture process, therefore in precision control procedure, can increase extra cost; (3) if large-tonnage curvature-prevention support component adopts the cross section of integral form, must cause section area excessive, 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, after the whole machine-shaping of factory, will produce the difficulty in transportation.
Summary of the invention
The anti-buckling support of all steel lattice proposed by the invention adopts all steel member, and the inconvenience of having avoided concrete wet trade to bring, is convenient to carry out intense industrialization production more; By connecting floor, connect overhanging section of two inner core components, avoided traditional hinged anti-buckling supporting base end portion to be easy to occur the situation of local failure; Adopt a minute limb formula cross section, the interior nuclear cross section of curvature-prevention support component is launched more, 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 all steel lattice, is characterized in that, described anti-buckling support is by forming with lower member: two in-line kernel steel plate, two confining parts, batten plate, vulcanie, connection floor.
Described curvature-prevention support component is comprised of two minutes limbs, and within described minute, limb comprises a confining part and is wrapped in its inner in-line kernel steel plate; Totally two of described in-line kernel steel plate, paste vulcanie in the area surfaces of its restrained member parcel.
Totally two of described confining parts, measure-alike, its length is less than the length of in-line kernel steel plate; Described confining part adopts four plate weldings to form, and wherein two flat boards are longer, forms overhanging section of confining part plate.
Described batten plate is rectangle plain plate, along anti-buckling bearing length direction, is equidistantly arranged between two minutes limbs, forms axis bilateral symmetry arrange in pairs at two minutes limbs; Batten plate adopts three corner weld seams to be connected with overhanging section of plate of confining part of both sides.
Described connection floor is rectangle plain plate, and its length equates with the overhanging intersegmental 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 have 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 rigidly connects; Described being articulated and connected, by open single pin hole on connection floor, and is connected realization with the otic placode being fixed on described structural framing by bearing pin; Describedly rigidly connect connection, by opening bolt hole connecting on floor, and by high-strength bolt, be connected realization with the cover plate being fixed on described structural framing.
The present invention proposes a kind of novel anti-buckling support of all steel lattice, have the following advantages:
(1) adopt a minute limb formula cross section, the interior nuclear cross section of curvature-prevention support component is launched more, 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 member, between its parts, adopt and be welded to connect, Ke factory global formation, the inconvenience of not only having avoided concrete wet trade to bring, is convenient to carry out intense industrialization production more;
(3) by connecting floor, connect overhanging section of two inner core components, increased the bending rigidity of overhanging section of kernel, avoided traditional hinged anti-buckling supporting base end portion to be easy to occur the situation of local failure.
