The invention discloses an annual ring type reinforced high-strength concrete square column, comprising a concrete square column body and a reinforcing cage embedded in the concrete square column body, wherein the reinforcing cage comprises square spiral hoops, circular spiral hoops, first longitudinal bars, second longitudinal bars and transverse radial steel bars; the first longitudinal bars are longitudinally banded or welded on the square spiral hoops to form square reinforcing cages; the second longitudinal bars are longitudinally banded or welded on the circular spiral hoops to form circular reinforcing cages; a plurality of circular reinforcing cages are sleeved sequentially with diameters decreasing in the square reinforcing cages, and the transverse radial steel bars are transversely banded or welded on the square reinforcing cages and each circular reinforcing cage. According to the annual ring type reinforced high-strength concrete square column, the sectional dimension of the column can be reduced, the effective usable area of a building can be increased, and the defect of complex processes in producing a reinforced concrete column with a big cross section in the prior art is overcome. The annual ring type reinforced high-strength concrete square column has the characteristics of simple structure, quick speed of construction and high bearing capacity, and is suitable for substratum columns of high-rise buildings, columns of industrial heavy-duty factory buildings and bridge piers of long-span bridges.
Description
Technical field
The invention belongs to erecting to load-bearing component in field of civil engineering, it is specifically related to year wheeled arrangement of reinforcement high-strength concrete square column.
Background technology
Steel Concrete uses material the most widely in field of civil engineering. Along with the continuous increase of building height and span, pillar cross section size in the load larrying member of building top is also increasing, in Highrise buildings, more than the 1 meter pillar even reaching 2 meters is very common, while pillar cross section increases, in post, the number of steel bars of configuration is also multiplied, and then causing Steel Reinforcement Cage construction technology complicated, stirrup amount of finish increases, the problems such as construction speed is slow. The compound stirrup that wherein the many employings of stirrup part are made up of single closed rectangular stirrup and multiple tension rib, the shaping of this compound stirrup through reinforcement metal straightening, cutting, bending, colligation Deng Duo road manufacturing procedure, to be needed at substantial material resources manpower.
In Highrise buildings, the pillar of huge cross section size also can cut down effective usable floor area in building, and for reducing the cross section of pillar as far as possible, current main flow way adopts high-strength concrete, namely reduces column dimensions by improving concrete strength under identical loading action. But, high-strength concrete has ductility difference that the shortcoming of brittle rupture easily occurs, and can reduce the anti-seismic performance of building structure, for overcoming this problem, solves often through the configuration amount increasing stirrup again. The increase of stirrup consumption, causes steel bar meter amount and complexity to increase severely again, and increases and concrete build difficulty.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of simple structure, speed of application soon, year wheeled arrangement of reinforcement high-strength concrete square column that bearing capacity is high.
The present invention solves the problems of the technologies described above with following technical scheme:
Year wheeled arrangement of reinforcement high-strength concrete square column, the Framework Of Steel Reinforcement comprising concrete square cylinder He being embedded in concrete square cylinder, described Framework Of Steel Reinforcement comprises square spiral stirrups, circular spiral stirrup, the first vertical muscle, the 2nd vertical muscle and transverse direction radial steel reinforcement; First indulges the longitudinal colligation of muscle or is welded on square spiral stirrups to form square Steel Reinforcement Cage; 2nd indulges the longitudinal colligation of muscle or is welded on circular spiral stirrup the circular Steel Reinforcement Cage of composition; Press diameter sheathed multiple circular Steel Reinforcement Cage successively from big to small in square Steel Reinforcement Cage, horizontal radial steel reinforcement transverse binding or be welded on square Steel Reinforcement Cage and each circle Steel Reinforcement Cage.
The described square column length of side >=800mm.
Distance between adjacent two circular spiral stirrups is not less than 100mm.
Distance between square spiral stirrups and adjacent circular spiral stirrup is greater than 10mm and is less than 50mm.
