By using the special-shaped composite concrete-filled steel tube column with the spiral stirrups, the bearing capacity and the ductility of a member are improved, and meanwhile, the modularized production and assembly of the special-shaped composite concrete-filled steel tube column are realized.
Description
Technical field
The invention belongs to the building structural member technical field, be specifically related to a kind of combined steel pipe concrete profiled pile and preparation method of joining spiral stirrup.
Background technology
Concrete filled steel tube is a fill concrete and forming in the steel pipe, and steel pipe and core concrete thereof can bear the structural element of external load effect jointly.Because the supporting role of fill concrete can prevent that the steel pipe tube wall from too early flexing taking place in advance, steel pipe is to the effect of contraction of core concrete simultaneously, thereby makes concrete filled steel tube have very high bearing capacity; Advantages such as concrete filled steel tube also has plasticity and good toughness simultaneously, and shock resistance is strong.Therefore, concrete filled steel tube has broad application prospects.
Avoid the outstanding influence of room corner post corner angle for satisfying building requirements in the architectural design to sighting within doors and taking up room; Improve the flexibility that premises furniture is arranged; Post jamb and infilled wall have obtained using widely with thick shaped rc columns structure; But concrete is easy to crack, thereby the shearing resistance of post and antitorque bearing capacity are relatively poor, so shock resistance is not enough.Also have at present some scholars to propose the section form of multiple steel pipe concrete profiled pile, but when flakiness ratio is big, exist steel pipe not strong to the concrete restriction ability, easily too early flexing reduces bearing of component.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, overcome the defective of existing shaped rc columns, provide a kind of ductility good, the hetermorphiscal column that bearing capacity is higher antidetonation ability and steel core concrete column.Technical scheme of the present invention is following:
A kind of combined steel pipe concrete profiled pile of joining spiral stirrup; Comprise the steel pipe more than three or three; With one of them steel pipe is the center steel pipe, links to each other through junction plate between other each steel pipes and the center steel pipe, in each steel pipe, is placed with spiral stirrup; And being cast with concrete, each junction plate is provided with many stiffening ribs.
As preferred implementation, the stiffening rib that is arranged on each junction plate is vertical each other with junction plate, and many stiffening ribs are Z-shaped; Described steel pipe is square steel pipe or round steel pipe; The cross sectional shape of described combined steel pipe concrete profiled pile is L shaped, T shape or cross.
The present invention provides a kind of above-mentioned preparation method of joining the combined steel pipe concrete profiled pile of spiral stirrup simultaneously, and step is following:
1) prefabricated steel pipe, junction plate, stiffening rib and spiral stirrup;
2) on the different edge of center steel pipe or different parts, be welded to connect plate respectively, again other steel pipes be welded in the other end of different junction plates respectively;
3) between the steel pipe of junction plate both sides, weld some stiffening ribs perpendicular to junction plate;
4) in each steel pipe, place spiral stirrup and middle concreting maintenance in steel pipe, form the combined steel pipe concrete profiled pile of joining spiral stirrup.
The present invention has overcome the deficiency of the hetermorphiscal column of existing concrete filled steel tube; Particularly overcome in the bigger concrete filled steel tube of flakiness ratio steel pipe to the deficiency of core concrete restriction ability; Thereby improved bearing of component and ductility, realized the production of steel pipe concrete profiled pile, the modularization of assembling simultaneously.Construction is made, and designs also simple relatively.Specify as follows:
(1) spiral reinforcement of configuration has strengthened the effect of contraction of steel pipe to core concrete, and concrete plasticity is fully played, and has strengthened the bearing capacity and the ductility of steel pipe concrete profiled pile;
(2) single concrete filled steel tube intercolumniation can be adjusted, and realizes bigger bending rigidity easily, and realizes the equistability of two main shafts easily;
(3) production of steel pipe concrete profiled pile, the modularization of assembling have been realized.Construction is made, and designs also simple relatively.
