In order to reach above purpose, the solution that the present invention adopts is:
A kind of high-strength concrete column, comprise the conventional peripheral concrete post of forming by longitudinal reinforcement and stirrup, be characterised in that also to comprise the high-strength concrete stem stem that is positioned at peripheral concrete post centre position, the high-strength concrete stem stem is made up of high-grade longitudinal reinforcement and high-grade spiral stirrup.
High-strength concrete column as mentioned above, wherein the ratio of the cross section diameter of a circle that surrounded of stem stem spiral stirrup and peripheral concrete column section width is between 1/4~1/3.
High-strength concrete column as mentioned above, stem stem and peripheral conventional concrete column all adopt the high-strength concrete of strength grade between C50~C100.
High-strength concrete column as mentioned above, wherein the high-strength concrete stem stem is fixedlyed connected with the compound stirrup on the peripheral concrete post.
High-strength concrete column as mentioned above, wherein said being fixedly connected as pricked silk colligation or spot welding.
Selecting for use of above-mentioned peripheral pillar longitudinal reinforcement and compound stirrup is identical with conventional concrete column.
Innovation of the present invention is: the core at conventional concrete column adopts the stem stem of being furnished with high-grade vertical muscle and high-grade spiral stirrup, axial compressive strength and flexural strength have so promptly been improved, also make in the joint core zone simultaneously, the reinforcing bar of beam column can pass through smoothly, do not need special structure to handle, compare the reduction cost with steel reinforced concrete, save material, the reduction of erection time.
Vertical muscle of stem stem and stem stem spiral stirrup adopt HRB400 and HRB335 grade reinforcing steel, and concrete intensity parameter is seen " Code for design of concrete structures " (GB50010-2002).
The cross section of concrete column of the present invention is thought of as square or rectangle.
The difference of the present invention and prior art is: on the basis of conventional concrete column, also be furnished with high-grade vertical muscle and high-grade spiral stirrup formation stem stem in the central area of post, do not appear in the newspapers before this new reinforcing steel bar concrete column.
Owing to adopted above method, the present invention has following characteristics: spiral stirrup makes the core concrete three dimension stress improve the axial compressive strength of core concrete; Bear a power with the core longitudinal reinforcement and be better than bearing a power with peripheral reinforcing bar, peripheral reinforcing bar need be resisted the effect of moment of flexure, and moment of flexure is little to the influence of core reinforcing bar; After concrete cover ftractureed, peels off, peripheral reinforcing bar and concrete bonding weakened, and still have good bonding between core reinforcing bar and the concrete; The core reinforcing bar can not buckled; Even peripheral concrete destroys, be furnished with the stem stem of reinforcing bar and still can resist vertical load and certain horizontal loading, prevent big shake structural collapse down.The stem stem size of arrangement of reinforcement is less simultaneously, and the reinforcing bar that is easy to beam passes frame joint, and it is simple that node area reinforced concrete beam column arrangement of reinforcement structure is handled, greatly convenient construction.
