Description

The polygon steel pipe concrete column that reinforcing bar is put more energy into
Technical field
The present invention relates to a kind of steel core concrete column.
Background technology
Square, rectangle or polygon steel pipe concrete are because outside steel pipe to concrete effect of contraction, can effectively improve concrete ductility.Compare with reinforced concrete post square, rectangle or polygon steel pipe concrete have bearing capacity height, ductility good, save advantages such as template, speed of application be fast; Compare with concrete-filled circular steel tube column and to have that the cross section bending rigidity is big, joint structure simple, be easy to characteristics such as finishing, be subjected to numerous owners' welcome, the engineering application is increasing.But because square, rectangle or polygon steel tube section are made up of a plurality of straight flanges, same section steel pipe is inhomogeneous to the effect of contraction of core concrete, the bight constraint is the strongest, the constraint of straight flange middle part is the most weak, so the concrete filled steel tube of square, rectangle or the concrete bearing capacity of polygonal steel pipe, the equal sectional dimension of ductility is low, and cripling easily takes place in tube wall, makes steel and concrete intensity not to make full use of.For avoiding steel plate to occur cripling too early, limit square, rectangle or polygonal steel pipe flakiness ratio, make the steel plate tube wall thicker, increased steel using amount and welding difficulty.Occurred at present adopting the method that steel plate stiffening rib or binding bar are set, prevented steel plate generation cripling and improve the effect of contraction of steel pipe core concrete.But there are shortcomings such as steel using amount is big, processing and fabricating cost height in the steel core concrete column of band steel plate stiffening rib; And the steel core concrete column of belt restraining pull bar exists binding bar cost height, a large amount of perforates of steel pipe, concreting easily to run shortcomings such as slurry, construction complexity, and engineering is used few.
Summary of the invention
Thickness of steel pipe is big in order to solve in common square, rectangle or the polygon steel pipe concrete column, the welding difficulty, steel using amount is big, steel pipe is strong to the concrete effect of contraction, the strength of materials is underutilized, and problems such as band steel plate stiffening rib or binding bar steel core concrete column complex structure, steel using amount are big, cost height the invention provides the polygon steel pipe concrete column that a kind of reinforcing bar is put more energy into.
The present invention includes polygonal steel pipe, reinforcing bar stiffening rib and concrete filled, the steel pipe of filling with concrete filled is a polygonal steel pipe, be welded with the reinforcing bar stiffening rib at the inwall of polygonal steel pipe along the axis direction of polygonal steel pipe, the local configuration after the described reinforcing bar stiffening rib clod wash processing is square, triangle or trapezoidal.
The present invention is that a kind of simple structure, easy construction, cost are low, can effectively prevent square, rectangle or polygonal steel pipe generation cripling, 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, novel square, the rectangle of easy construction, good economy performance or polygon steel pipe concrete column.
That the reinforcing bar that the present invention proposes is put more energy into is square, rectangle or polygon steel pipe concrete column have following advantage:
1, compare with concrete-filled circular steel tube column have that the cross section bending rigidity is big, joint structure is simple, be easy to characteristics such as finishing.
2, improved in common square, rectangle or the polygon steel pipe concrete column steel pipe to the concrete effect of contraction not strong and uneven characteristics, can effectively prevent steel plate generation cripling, thereby increase the flakiness ratio limit value of steel pipe walls, reduce thickness of steel pipe, save steel, reduce the welding difficulty, steel and concrete intensity are fully used.Steel pipe can further improve the bearing capacity and the ductility of square, rectangle or polygon steel pipe concrete column to concrete operative constraint effect, improves its anti-seismic performance.
3, overcome that the belt restraining pull bar is square, rectangle or polygon steel pipe concrete column binding bar cost height, a large amount of perforates of steel pipe, concreting easily run shortcomings such as slurry, construction complexity.
4, square, the rectangle or the shortcomings such as polygon steel pipe concrete column steel using amount is big, processing and fabricating cost height of band steel plate stiffening rib have been overcome, can strengthen collaborative work between steel pipe and concrete by connecting lacing wire simultaneously, its ductility and bearing capacity are further enhanced.
