Description
Technical field
The utility model belongs to the Structural Engineering field in the civil engineering, particularly a kind of high level and super highrise building concrete filled steel tube zeugopodium formula truss combination construction.
Background technology
China is built or at the forefront in the world at the high level of building or super highrise building number of bits at present, according to incompletely statistics, ends 2011, and the built or mansion of calculated height above 300 meters reached 15.The design of these high levels or super highrise building and building course have also played huge promotion and innovation effect to the development of Building technology and construction theory.
In existing high level and super-high building structural system, along with the structural system type is different, and because the increase of height, sectional dimension of members has the trend of increase, in the huge trussed construction such as Hong Kong Bank of China Tower, the sectional dimension of the solid corner post of steel concrete is 4.8 meters * 4.1 meters, and the steel truss sectional dimension in Tokyo town hall No. 1 building of mansion is 6.4 meters * 6.4 meters, and the huge column cross-section size of the steel reinforced concrete at center, Shanghai is 3.7 meters * 5.3 meters.Utilize solid concrete member or real abdomen formula steel member just to relate to problems such as casting of concrete in mass and the processing of steel work slab at this yardstick, and the scantling size still is restricted, is unfavorable for further improving structure height.
Concrete filled steel tube is the structure that fill concrete forms in steel pipe.When stressed, the outer steel pipe of concrete filled steel tube has formed effective constraint to core concrete common.Owing to take full advantage of the material behavior of steel tension and concrete anti-compression, encased structures has the advantages such as bearing capacity height, rigidity are large than the steel work of same cross-sectional size or concrete structure.Therefore the characteristics such as in addition, encased structures also has the saving template, and speed of application is fast, and antidetonation, fire resistance are good just more and more are applied in high level and Super High structure.The characteristics such as the steel pipe concrete truss structure of development utilizes concrete filled steel tube as chord member on this basis, and empty steel tubular structure has the cross section and carries out as web member, and rigidity is large, and non-deformability is strong.The web member of existing trussed construction mostly is sky steel pipe or steel work, destroys mostly to be web member cripling or weld seam destruction, and the strength capabilities of chord member can not be not fully exerted.Therefore in the urgent need to a kind of cross section carry out, intensity is high, rigidity is large, construction is convenient, anti-seismic performance good, from the structural element of heavy and light and accordingly form of structure adapt to the higher demand of high level and Super High Structural Engineering aspect.
Summary of the invention
The purpose of this utility model is can adapt to high-rise and super-high building structure higher requirement aspect use function and structure height for following design high-rise and super-high building structural system provides a solution.
The purpose of this utility model is achieved through the following technical solutions, consisted of by concrete filled steel tube zeugopodium formula girder truss, concrete filled steel tube zeugopodium formula truss support and concrete filled steel tube zeugopodium formula truss leg, some concrete filled steel tube zeugopodium formula girder trusses and some concrete filled steel tube zeugopodium formula truss leg cross arrangements consist of the quadrangle array, and a concrete filled steel tube zeugopodium formula truss support that angle point is connected with quadrangle is set in each quadrangle;
Described concrete filled steel tube zeugopodium formula girder truss, concrete filled steel tube zeugopodium formula truss support and concrete filled steel tube zeugopodium formula truss leg are concrete filled steel tube zeugopodium formula truss, concrete filled steel tube zeugopodium formula truss by 2 ~ 10 concrete filled steel tube chord members along its length by flange or be welded to connect formation, between the different concrete filled steel tube chord members by concrete-filled tube web with flange or be welded to connect.
The cross section of described concrete filled steel tube chord member is rectangle, circle or oval.
The cross section of described concrete-filled tube web is rectangle, circle or oval.
The outer tube material of described concrete filled steel tube chord member and concrete-filled tube web is common iron, high-strength steel or stainless steel.
The core concrete material of described concrete filled steel tube chord member and concrete-filled tube web is ordinary concrete or high-strength concrete.
The limb number of the concrete filled steel tube chord member of described single concrete filled steel tube zeugopodium formula girder truss, concrete filled steel tube zeugopodium formula truss support or concrete filled steel tube zeugopodium formula truss leg is 2 ~ 8 limbs.
The utility model can be done following improvement:
Concrete filled steel tube zeugopodium formula truss combination construction can combined with steel reinforced concrete shear wall and Reinforced Concrete Core Walls Structure, forms outside framework and adopts concrete filled steel tube zeugopodium truss, the inner combination construction that adopts reinforced concrete shear wall or Core Walls Structure.
The periphery of concrete filled steel tube zeugopodium trussmember own can the combined with steel reinforced concrete member, buries the steel concrete wall member of concrete filled steel tube zeugopodium truss in the formation, to obtain larger rigidity and bearing capacity.
The beneficial effects of the utility model are:
(1) this structure Path of Force Transfer is clear and definite, and rigidity is large, and good stability is applicable to the building of high altitude and span more.
(2) the zeugopodium trussmember with effective distribution of material around, carry out in the cross section, chord member and web member all adopt concrete filled steel tube, rigidity is large, bearing capacity is high.Owing to adopt trussed construction, compare with common solid component and in same section area situation, avoided ultra-large volume concrete the work such as to build, also can more effectively utilize the performance of material.Because zeugopodium has been filled concrete, has effectively avoided the steel pipe flexing, has improved rigidity, can reduce or partly substitute the application of shear wall.
(3) antidetonation, wind resistance, fire resistance are good.Because chord member inside is fill concrete also, higher than conventional steel concrete truss supporting capacity, rigidity is larger, effectively improves the node region performance.Larger than conventional steel structural damping, wind resistance is good, and better fire resistance is arranged.
(4) space availability ratio is high.The inner space of girder truss and truss leg can be utilized effectively, such as escalator etc. is set.Floor system can directly be built on main frame, also can adopt and hang floor slab structure etc., and layout can be versatile and flexible.
(5) the structural system deadweight is lighter, and damping ratio is larger.
(6) speed of application is fast.The agent structure basic building block can be prefabricated, on-the-spot substantially do not need assembling reinforcement when building main structure and build the work such as concrete blinding.
