Description
Technical field
The utility model belongs to field of civil engineering, relates to building structure, relates in particular to a kind of aluminium alloy sleeve barrel constraining anti-buckling steel pipe braced structures.
Background technology
It is a kind of principal mode that steel work supports that steel pipe supports, because its easy construction, good looking appearance, power transmission are clear and definite, is being applied in a large amount of engineering practices at present.
Under the geological process, the steel pipe support is mainly born repeatedly and is axially drawn, the pressure effect, and under the axial compression effect, steel pipe supports easy generation partial buckling destruction and low order integral body buckling instability destroys, thereby morning, destruction was deactivated, and can't play the energy-dissipating and shock-absorbing effect.For effectively improving low order that steel pipe the supports defective of buckling, both at home and abroad consider to adopt external wrapping concrete sleeves, mortar sleeve and steel bushing to come steel pipe supported to apply radial constraint more, forming does not have the bonding steel pipe and supports or prevent that the flexing steel pipe supports, and generally is called for short BRB and supports.At present, applicable cases shows, adopt concrete sleeve, mortar sleeve construction cumbersome, and adopt the steel bushing construction also pretty troublesome, and the steel bushing deadweight is big and the very poor brushing corrosion resistant coating that needs of decay resistance, therefore, at present, concrete sleeve, mortar sleeve and steel bushing steel pipe support on the high side at present and use also fewer.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of aluminium alloy sleeve barrel constraining anti-buckling steel pipe braced structures, it is by supporting external surface suit aluminium alloy sleeve barrel at tradition steel pipe commonly used, make steel pipe support the good radial constraint effect that is subjected to, prevent that steel pipe is supported on following cripling and the whole unstable failure of low order of taking place of the effect of axial compression repeatedly that geological process produces, effectively improve steel pipe and support energy dissipation capacity and supporting capacity, thereby make all types of structures of laying aluminium alloy sleeve barrel steel pipe support of the present utility model have the good resistance shock stability, improve the engineering structures antidetonation ability of taking precautions against natural calamities, have construction install convenience, excellent earthquake resistance, the characteristics of corrosion resistance and good.
In order to achieve the above object, the technical solution adopted in the utility model is:
Aluminium alloy sleeve barrel constraining anti-buckling steel pipe braced structures, comprise steel pipe braced structures 1, be coated with at the external surface of steel pipe braced structures 1 and be brushed with lubrication oil, the suit aluminium alloy sleeve barrel 2 then, the length of described steel pipe braced structures 1 is greater than the length of suit aluminium alloy sleeve barrel 2, expose at the two ends of steel pipe braced structures 1 behind the suit, fixing with steel pipe braced structures 1 with latch 4 at any end of aluminium alloy sleeve barrel 2.
The two ends that described steel pipe braced structures 1 exposes are provided with junction plate 3.
The utility model compared with prior art has the following advantages:
1) excellent earthquake resistance: because steel pipe supports the aluminium alloy sleeve barrel that the outside is with very big radial constraint rigidity in the utility model, and almost be in no bond state between aluminium alloy sleeve barrel and the steel pipe, therefore, steel pipe supports to bear again and can be subjected to the good radial constraint effect of aluminium alloy sleeve barrel under the axial compression effect repeatedly, cripling and whole unstable failure can not take place, thereby can effectively utilize and bring into play steel pipe and support the energy-dissipating and shock-absorbing effect, support employing low-yield steel as steel pipe, the aluminium alloy sleeve barrel steel pipe supports will have excellent more energy-dissipating and shock-absorbing effect.
2) easy construction: make because aluminium alloy sleeve barrel can carry out extrusion modling by mould, therefore, the aluminium alloys outer sleeve is easy to make, precision is higher; The steel pipe stayed surface only needs brushing lubrication oil simultaneously, need not to paste non-cohesive material, and the slit does not have strict restriction between steel pipe support and the aluminium alloy sleeve barrel, therefore, aluminium alloy sleeve barrel constraining anti-buckling steel pipe support production process of the present utility model is simple, precision is controlled easily, assemble easy.
3) corrosion resistance and good: what the aluminum alloy sleeve tube outer surface had one deck densification is to modify passivation layer, under various atmospheric environments, all has the good corrosion resistance energy, therefore, the utlity model has excellent corrosion resisting performance, under various corrosive environments, adopt to have advantage more.
4) repair conveniently: behind violent earthquake, generally be that steel pipe supports damage, aluminium alloy sleeve barrel does not have apparent damage, generally can reuse, therefore, can be when after shake, repairing with whole support dismounting, extract the steel pipe support out replacing, utilize the anti-flexing steel pipe support of aluminium alloy sleeve barrel making new aluminum alloy restraining sleeve of dismantling to be changed again and get final product.
5) draw materials conveniently: the aluminium alloy sleeve barrel processing and fabricating that the utility model adopts is convenient, and common steel tube is wide in variety, complete in specifications, purchase is convenient; Domestic very big steel mill can make the low-yield steel pipe.
6) applied range: be applicable to the various form of structure that adopt steel to support, comprise that construction steel supports, bridge supports with steel with steel support, electric power pylon and ocean platform and all can adopt steel pipe of the present utility model to support, range of application is extremely extensive.
