Abstract
The utility model discloses a joist steel regionally confined concrete column with longitudinal bars. The joist steel regionally confined concrete column comprises a concrete column (1), wherein a group of joist steel (2) used for confining the overall dimension of the concrete column (1) is arranged at the two sides in the concrete column (1); a group of stirrups or steel plate hoops (3) which are uniformly distributed along the concrete column (1) axially are arranged outside the joist steel (2); and a group of longitudinal bars (4) are arranged between the joist steel (2) and the stirrups or steel plate hoops (3). The joist steel regionally confined concrete column has the beneficial effects that the joist steel is used instead of partial longitudinal bars in the existing concrete columns, serves as the longitudinal carrying bar and simultaneously connects the stirrups or steel plate hoops, the longitudinal bars and profile steel into a steel framework by way of regional confinement to well confine the concrete among the stirrups or steel plate hoops, the longitudinal bars and the profile steel so as to improve the bearing capacity and anti-seismic property of the component; and meanwhile, the quantity of reinforcement and reinforcement difficulty in the concrete column are greatly reduced.
Description
Technical field
The utility model relates to a kind of i iron region constrained concrete post with vertical muscle.Belong to building concrete post technical field of construction.
Background technology
Along with the develop rapidly of building trade, various high levels, super highrise building get more and more, and the load of pillar is also increasing, and the pillar cross section is also increasing.For this reason, the existing concrete post generally all is with adopting steel reinforced concrete or strengthening concrete partly to substitute reinforcing bar, to reach the purpose in control cross section, when shaped steel is configured in the pillar middle part, effect to the pillar bending resistance is little, and causing quantity of reinforcement increases, and outsourcing steel concrete pillar is not owing to consider effect of contraction, and its operating efficiency is not high yet.
Summary of the invention
The purpose of this utility model is, discloses a kind of i iron region constrained concrete post with vertical muscle.Give full play to the efficient of shaped steel and constraint, solve that the existing concrete column section is big, quantity of reinforcement greatly and do not bring into play the problem of binding effect, to overcome the deficiencies in the prior art.
The technical solution of the utility model:
A kind of i iron region constrained concrete post with vertical muscle comprises concrete column, and the two sides in the concrete column are provided with one group of i iron that is used for confined concrete post appearance and size, and i iron is provided with one group outward along axial uniform stirrup or the steel plate hoop of concrete column; Between i iron and stirrup or steel plate hoop, be provided with one group of vertical muscle.
In the aforementioned concrete column, the cross section of described concrete column is square or the rectangle of different sizes, is provided with at least four i iron in the concrete column.
In the aforementioned concrete column, described stirrup or steel plate hoop are straight-flanked ring, and stirrup or steel plate hoop are enclosed within the outer and i iron welding of i iron of two symmetries.
In the aforementioned concrete column, described along vertical arrangement between the axial uniform stirrup of concrete column or steel plate hoop layer and the layer.
In the aforementioned concrete column, described vertical muscle is located at the intersection point place, space of vertical arrangement stirrup or steel plate hoop.
Compared with prior art, the utility model is indulged muscle with the part that i iron substitutes in the existing concrete pillar, utilize i iron as the longitudinal stress reinforcing bar, with the range constraint mode stirrup or steel plate hoop, vertical muscle and shaped steel are connected into steel frame simultaneously, and concrete therebetween formed good constraint, to improve bearing of component and anti-seismic performance.Quantity of reinforcement and arrangement of reinforcement difficulty in the concrete post have also been reduced simultaneously greatly.
