Abstract
The invention discloses an annual ring type reinforced high-strength concrete circular column, comprising a concrete circular column body and a reinforcing cage embedded in the concrete circular column body, wherein the reinforcing cage comprises spiral hoops, longitudinal bars and transverse radial steel bars; the longitudinal bars are banded or welded with the spiral hoops to form a plurality of single-tube reinforcing cages with different diameters, and the single-tube reinforcing cages are sleeved sequentially with diameters decreasing and are respectively banded or welded with the transverse radial steel bars to form a reinforcing cage of a tube-in-tube structure. The high-strength concrete circular column disclosed by the invention 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 the vertical member of load larrying member in field of civil engineering, it is specifically related to year wheeled arrangement of reinforcement high-strength concrete cylinder.
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 will through reinforcement metal straightening, cutting, bending, colligation Deng Duo road manufacturing procedure, and shaping efficiency is lower.
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 cylinder 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 cylinder, the Framework Of Steel Reinforcement comprising concrete cylindrical He being embedded in concrete cylindrical, described Framework Of Steel Reinforcement comprises spiral stirrup, vertical muscle and transverse direction radial steel reinforcement; Indulge muscle and spiral stirrup colligation or it is welded to form monotubular Steel Reinforcement Cage; Monotubular Steel Reinforcement Cage has different multiple, sheathed successively from big to small of diameter, and respectively with horizontal radial steel reinforcement colligation or be welded to form in cylinder barrel structure Steel Reinforcement Cage.
Described body diameter >=600mm.
The distance of adjacent two monotubular Steel Reinforcement Cages is not less than 100mm.
The pitch of described spiral stirrup is 50mm～200mm, and is not more than 1/5th of screw diameter.
The diameter of described monotubular Steel Reinforcement Cage is 0.3～0.95 times of body diameter.
Central shaft and cylindrical center's axle of each monotubular Steel Reinforcement Cage overlap.
Substantive distinguishing features and the advantage of the present invention are:
The year of the present invention wheeled arrangement of reinforcement high-strength concrete cylinder, the distribution rule of inner steel bar copies the annual ring of trees trunk, in cylinder, high-strength concrete is provided multiple constraint effect by barrel structure Steel Reinforcement Cage, effectively improve the ductility of high-strength concrete, the cross section size of pillar can be effectively reduced under certain loading action, save material of construction, increase building usage space; Integral construction is simple, and the major part course of processing completes by automatic forming equipment, reduces comprehensive cost; It is applicable to the bridge pier of Highrise buildings bottom pillar, industrial heavy factory building pillar and long span bridge beam.
