Description
Technical field
The invention belongs to a kind of building structural element, particularly a kind of steel core concrete column.
Background technology
Odd-shaped cross section post post limb thickness and infilled wall be with thick, can avoid indoor occur post stupefied, be convenient to indoor layout, increase usable floor area, in rising trend in the application percentage of dwelling house and office building.Traditional hetermorphiscal column adopts steel concrete more, expose some problems in popularization and practical engineering application: the directionality to horizontal loading is very responsive, be the load action direction its bearing capacity difference is not bigger simultaneously, bearing capacity is lower, the strength of materials fails to make full use of; For guaranteeing the requirement of pillar ductility, need join a large amount of stirrups and strict restrictive axes pressure ratio; Cast in situs difficulty, node arrangement of reinforcement are more, concrete pouring quality is difficult to guarantee etc., have limited the promotion and application of hetermorphiscal column.Element bearing capacity improves special-shaped steel pipe concrete, ductility improves because outside steel pipe to concrete effect of contraction, can make, but need take measures to prevent that steel pipe generation cripling and cross section inner corner trim place's steel pipe and concrete break away from.The normal at present method that steel plate stiffening rib or binding bar are set that adopts, but there are shortcomings such as steel using amount is big, processing and fabricating cost height in the special-shaped steel pipe concrete post of band steel plate stiffening rib, and belt restraining pull bar special-shaped steel pipe concrete post exists binding bar cost height, a large amount of perforates of chapped pipe, concreting easily to run shortcomings such as slurry, construction complexity, and engineering is used all seldom.
Summary of the invention
For solve the shaped rc columns poor seismic behavior, bearing capacity is low, construction is complicated and traditional special-shaped steel pipe concrete post complex structure, steel using amount is big, cost is high problem, the invention provides the special-shaped steel pipe concrete post that a kind of reinforcing bar is put more energy into.
The present invention includes chapped pipe, reinforcing bar stiffening rib and concrete filled, the steel pipe of filling with concrete filled is a chapped pipe, is welded with the reinforcing bar stiffening rib at the inwall of chapped pipe along the axis direction of chapped pipe.
The present invention is that a kind of simple structure, easy construction, cost are low, can prevent effectively that steel pipe generation cripling and cross section inner corner trim place's steel pipe and concrete filled break away from, strengthen the construction measure of steel pipe and concrete collaborative work, thereby obtain a kind of bearing capacity height, ductility is good, anti-seismic performance is superior, the novel special-shaped steel pipe concrete post of easy construction, good economy performance.
The special-shaped steel pipe concrete post that the reinforcing bar that the present invention proposes is put more energy into has following advantage:
1, post limb thickness and infilled wall be with thick, can avoid indoor occur post stupefied, be convenient to indoor layout, increase usable floor area.
2, shortcomings such as shaped rc columns court of a feudal ruler property is poor, limit value of axial compression ratio is little, arrangement of reinforcement is many, concreting is difficult, construction complexity have been overcome, but chapped pipe double as concrete blinding and construction skeleton, steel pipe can significantly improve the bearing capacity of pillar and improve its ductility concrete operative constraint effect.
3, overcome belt restraining pull bar special-shaped steel pipe concrete post binding bar cost height, a large amount of perforates of chapped pipe, concreting and easily run shortcomings such as slurry, construction complexity, strengthened the collaborative work between steel pipe and concrete simultaneously, its ductility is further improved.
4, shortcomings such as the special-shaped steel pipe concrete post steel using amount of being with the steel plate stiffening rib is big, processing and fabricating cost height have been overcome.
