Description
Technical field:
The utility model relates to a kind of building structural element, and particularly a kind of no flexing energy dissipating is supported.
Background technology:
As everyone knows, modern building structure all will be considered the antidetonation of structure, especially is built in the building of earthquake zone, and structure Design also needs to consider wind resistance in addition, and steel work is widely used in many civil engineerings owing to good material property.Along with expanding economy and quickening of urbanization process, the quantity of high-rise building is constantly increasing, and wherein with steel work and steel and concrete combined structure proportion maximum.The existing building structural system adopts bending resistance steel frame system, support frame structure and dual structure architecture mostly, and wherein commonly used with the moment resisting system.But for the highrise building of moment resisting system, become gentle relatively owing to the height of building makes its structure, the distortion of structure often surpasses the sidesway limit value of regulation and stipulation, so structure just needs to improve whole rigidity.In addition, under the effect of violent earthquake, structure can produce excessive nonlinear deformation, often causes shake back structure repair difficulty or rehabilitation cost too high, thereby does not meet economic requirement.Support frame structure has better economic, but because traditional support steel structure system can produce flexing when supporting pressurized, so often need to strengthen the section of support to meet design requirement, from and reduced its economy, nonetheless, still can not guarantee under strong motion, to avoid the generation of flexing.In view of this, the member that more external software engineering researchers invent do not have flexing to take place when going out a kind of pressurized, be called buckling-restrained support (Buckling-Restrained Braces) or do not have flexing energy dissipating support, they are used in high building structure as damper.At present, no flexing energy dissipating is supported and has been obtained extensive use in countries such as Japan, the U.S., Canada.
Common be supported on to bear when axial compression reaches certain limit the flexing phenomenon will take place, after flexing takes place, support and just lost supporting capacity, no flexing energy dissipating is supported flexing can not taken place when bearing axial compression, but surrender the same with tension, thereby can absorb the energy of the whole system of input in a large number, therefore can be used as a damping unit.
No flexing energy dissipating is supported and generally is made up of following three essential parts: axle power member unit, buckling-restrained unit and linkage unit.Axle power member unit is positioned at the axle center, buckling-restrained cell rings wrap in it around, linkage unit is at two ends of axle power member unit.
When axle power member unit pressurized,, make a power member unit flexing can not take place owing to be subjected to the constraint of outside buckling-restrained unit.When pressure reaches certain limit, thereby axle power member unit can be surrendered the energy of dissipation input system.It generally is to be connected on the bean column node of steel structure frame with the form that the axle center is supported that no flexing energy dissipating is supported, and it mainly is used as horizontal force resistant (wind or the earthquake) member of structure.Under horizontal loads, flexing does not take place as long as support, the energy that it just can absorb input system has played the effect of the damper of structure.
1988, disclosed a kind of common no flexing energy dissipating in the paper that publishes on the constructionism collected works 34B of the Architectural Institute of Japan volume " by the research of the no bonding support of buckling-restrained concrete and steel tube confinement parcel " (A study on the unbondedbrance encased in buckling-restraining concrete and steel tube) and supported, Fig. 1 and Fig. 2 are seen in its structure and installation.The axle power member unit 11 that no flexing energy dissipating support 10 shown in the figure is made of steel plate, the buckling-restrained unit 12 that square steel pipe constitutes, the filler cells 13 that concrete constitutes, unsticking order unit 14 and the linkage unit 15 that chemical material constitutes are formed, the one end is connected on the node of the post 20 of steel work and beam 30, and its other end is connected on another node of this steel frame.Steel plate 11 bears a power load; Flexing takes place from steel plate 11 being formed constraint on every side to prevent steel plate 11 in square steel pipe 12 and concrete 13 when being carried to certain limit; Unsticking order unit 14 can cut off steel plate 11 and concrete 13, so that can free telescopic slide during steel plate 11 pressurizeds and deform when surrender; Steel plate 11 extends the outside of square steel pipe 12, and vertically is welded with upright strengthening steel slab 16 in its end, to prevent not having external constraint and issuable flexing.Thereby the extension end of steel plate 11 and strengthening steel slab 16 have just formed the section (seeing Fig. 2 A-A section) of "+" font have constituted linkage unit 15 like this, and the two orthogonal junction plates that are made of steel plate that stretch out on this linkage unit 15 and the steel structure node are by being connected batten plate and bolt couples together.The topmost shortcomings that 10 existence are supported in above-mentioned existing no flexing energy dissipating are that the syndeton of end is very complicated, bean column node must stretch out two orthogonal junction plates, need 8 to connect batten plate, at least 16 connecting bolts in addition altogether, linkage unit 15 and junction plate are connected and fixed.This has expended a large amount of connection material and artificial on the one hand, on the other hand owing to very high to the required precision that connects, thereby has also strengthened manufacturing and mounting hardness.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the utility model provides a kind of double steel plate easy to manufacture, easy to connect, that save cost to connect no flexing energy dissipating and has supported.
The technical scheme in the invention for solving the technical problem is:
A kind of double steel plate connects no flexing energy dissipating to be supported, include a power member unit, buckling-restrained unit and linkage unit, this power member unit is made of steel plate, described linkage unit is made of two block plates, one end of this two steel plate is welded on the top and bottom of the steel plate end of a power member unit abreast, its other end stretch out buckling-restrained unit the outside and above offer connecting through hole, have between this two steel plate one equidistant at interval.
Double steel plate described in the utility model connects no flexing energy dissipating support and also includes unsticking order unit, and this unsticking order unit is a silica gel; Described buckling-restrained unit can be the steel pipe of fill concrete, also can be to be made of steel concrete or fibrous concrete.
Compared with prior art, linkage unit of the present utility model is made of two parallel steel plates that are welded on a power member unit end, therefore only needing to insert the framework that can be connected to structure in the interval between two steel plates by the monolithic junction plate gets on, thereby simplified the labyrinth of the linkage unit of existing no flexing energy dissipating support, not only saved lot of materials and artificial, and simplified manufacturing process, made things convenient for to install to connect.
