Abstract
The utility model discloses a reinforced concrete split column for a multi-story or a high-rise building, comprising two or four rectangle equal cross-section unit columns and a full section transition area which is arranged on the upper end and the lower end of the rectangle equal cross-section unit column, wherein a clapboard is arranged between each unit column and is in 8 to 100 mm thickness. The utility model could greatly improve the anti-seismic performance of the high-rise building and reduce the construction cost.
Description
The utility model more specifically says about multilayer or high-rise building, and the utility model is the support column of using about multilayer or high-rise building.
At present, multilayer and highrise building are increasing in builing industry, and they are very strict for the requirement of structure stress and anti-seismic performance.Reinforced concrete structure is still primary structure in the highrise building now because of its distinctive advantage.When design high-rise building bottom column, often be designed to short column or ultrashort post.Because the mode of failure of short column belongs to brittle fracture, all previous violent earthquake proves that all it is a key factor that causes reinforced concrete structure failure even collapse that short column destroys, and its consequence is catastrophic often.Therefore, the short column problem of easily being damaged has become problem demanding prompt solution in steel concrete multilayer and the highrise building.
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of branch scapus that significantly improves anti-seismic performance, reduces highrise building construction cost is provided.
The purpose of this utility model is achieved by following technical proposals:
Steel concrete of the present utility model divides scapus, is made of two or the transition region in four square equal cross-section body unit posts and whole cross section and the dividing plate between the unit post.Its thickness of dividing plate of described unit intercolumniation is 8-100mm.
Be provided with compound stirrup in the transition region of above-mentioned minute scapus, and its exopodite is than the big 2mm of diameter of interior limb.The height of described transition region is 80-200mm, highly being that 100mm is the best.Must not be less than 3 roads along transition region overall height stirrup, and the spacing between the stirrup is not more than 50mm.Described dividing plate adopts similar materials such as gypsum plank or rubber tile.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model split rod structure schematic diagram;
Fig. 2 is the utility model split column section schematic diagram;
Fig. 3 is that the utility model divides scapus transition region schematic cross-section;
Fig. 4 is that the utility model divides the interior limb structural representation of stirrup in the scapus transition region;
Fig. 5 is that the utility model divides stirrup exopodite structural representation in the scapus transition region.
In the drawings, the utility model divides scapus, is divided into the uniform section body unit post 3 of 4 rectangles by two dividing plates 1, and they can be that square also can be a rectangle, and its appearance and size and vertical muscle reinforcement ratio are identical.The length of side of each unit post 3 should not be less than 400mm, and its aspect ratio should not be greater than 1.5.3 vertical muscle employing symmetric reinforcement is leant in the unit, and its one-sided reinforcement ratio is not less than 0.2%.Should guarantee as far as possible in the construction that each unit post concrete strength equates.Dividing plate 1 its thickness is 8-100mm, is best with 10mm, and dividing plate 1 adopts similar materials such as gypsum plank or rubber tile.
Divide 4 unit post 3 upper/lower terminals of scapus to be provided with transition region 2, it is 80-200mm highly, is best with 100mm.
Transition region 2 adopts compound stirrups, interior limb 4 manufacture respectively with exopodite 5 and the diameter of exopodite 5 reinforcing bars than interior limb 4 big 2mm.In the overall height scope of transition region 2, stirrup must not be less than 3 roads, and the spacing between the stirrup is not more than 50m.。
It is to form by concrete monobloc cast behind the vertical muscle of designing requirement colligation and stirrup and the placement dividing plate with transition region 2 that the utility model divides each unit post 3 of scapus.
Steel concrete divides scapus and divides the seismic design of scapus framework should abide by national standard " concrete design specification " (revised edition in 2000) and " seismic design provision in building code " (revised edition in 2000), also should observe national existing relevant specification and rules.
The utility model compared with prior art has following good effect:
1. the structure of the utility model separated column can improve the anti-seismic performance of skyscraper, displacement Ductility significantly Coefficient can improve 4-8 doubly.
2. the structure of the utility model separated column is conducive to reduce skyscraper construction cost, reduces approximately building and makes Valency 6-9%.
3. the structure of the utility model separated column need not the additional requirements such as special material and special process, is easy to design And construction, do not need Special Training is carried out in design and workmen yet.
