Abstract

The invention relates to an indirect assembly concrete-filled steel tube combined special-shaped column and a production method thereof. The structure column comprises steel tubes, a studding piece, aconnecting plate, a bolt and concrete. The special-shaped column is composed by firstly welding the connecting plate on the steel tube, then leading the studding piece to be in bolt connection with t he connecting plate on the steel tube and connecting a plurality of steel tubes to form a steel tube combined special-shaped column with an L-shaped, T-shaped or cross-shaped cross section, and finally casting the concrete in the steel tubes. The method includes the beneficial effects of: the avoidance of a salient angle appearing at an indoor corner with the column wrapped in the wall, adjustablespacing of a single steel tube and the obtainment of large bending rigidity by using the steel tubes with a small cross section, factory-prefabricated components, on-spot bolt connection, fast constr uction speed and high precision. The special-shaped column is applicable to steel structure residences or office buildings.

Description

Indirect assembly concrete-filled steel tube combined special-shaped column and preparation method thereof
Technical field
The present invention relates to a kind of concrete filled steel tube combined special-shaped column, more particularly, relate to a kind of indirect assembly concrete-filled steel tube combined special-shaped column structure and preparation method thereof.
Background technology
Encased structures is that fill concrete constitutes in steel pipe, because the effect of contraction of steel pipe, core concrete is in the three dimension stress state during pressurized, improved concrete bearing capacity, and because concrete filling, prevented the too early flexing of steel pipe tube wall, and then reached the effect of 1+1>2, make it have intensity height, characteristics that anti-seismic performance is good, in addition, concrete filled steel tube also has advantages such as fireproof performance is good, construction is convenient, economic performance is good, and therefore, concrete filled steel tube is used for structural column and has great advantage.
But in dwelling house and office building, usually because excessive pillar cross section makes the building bight salient angle occur, the usable floor area and the furniture that influence the house are arranged.And modern people also more and more pay attention to the house usable floor area more and more higher to interior decoration and environmental requirement, if the bight salient angle problem that can avoid pillar to cause will be a much progress of dwelling house and office building.
Using special-shaped column structure just can avoid the phenomenon of indoor salient angle, and can obtain very big bending rigidity with less cross section, is a kind of pillar form that is suitable for dwelling house, office building.At present using more hetermorphiscal column is the shaped rc columns structure, but concrete is easy to crack, thereby the shearing resistance of post and torsional property are bad, thereby anti-seismic performance exists not enoughly, and construction is complicated, needs the work that installs of a lot of reinforcing bar bindings and template.
In order to solve the problem of indoor-bollard salient angle phenomenon, reinforced concrete post anti-seismic performance deficiency, need seek a kind ofly can guarantee ductility, can bring into play the pillar form of hetermorphiscal column advantage again.
