Abstract
The utility model discloses a channel steel area confined concrete column. The channel steel area confined concrete column comprises a concrete column (1), channel steel (2) for confining the appearance size of the concrete column (1), and a group of stirrups or steel plate hoops (3) axially and evenly distributed along with the concrete column (1) are arranged outside the channel steel (2). According to the channel steel area confined concrete column, the channel steel replaces longitudinal bars in the existing concrete column, and the stirrups, the longitudinal bars or steel plate hoops and profile steel are connected into a steel framework in an area confinement manner by utilizing the channel steel as longitudinally stressed reinforcement bars, good confinement on the concrete is formed, so that the bearing capacity and anti-shock performance of members can be improved. In addition, the reinforcement quantity in the concrete column can also be greatly reduced.
Description
Technical field
The utility model relates to a kind of channel-section steel region constrained concrete post.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 channel-section steel region constrained concrete post.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 channel-section steel region constrained concrete post comprises concrete column, is provided with the channel-section steel for confined concrete post appearance and size in the concrete column, and channel-section steel is provided with one group outward along axial uniform stirrup or the steel plate hoop of concrete column.
In the aforementioned concrete column, described channel-section steel is symmetrical arranged in twos, constitutes the opening rectangle.
In the aforementioned concrete column, the cross section of described concrete column is square or the rectangle of different sizes, is provided with the channel-section steel of at least two pairs of symmetries 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 outside two pairs of opening rectangles and with channel-section steel and weld.
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.
Compared with prior art, the utility model substitutes vertical muscle in the existing concrete pillar with channel-section steel, utilize channel-section steel 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.Also reduced simultaneously the quantity of reinforcement in the concrete post greatly.
