Description
Technical field
The utility model is related to bridge structure component technology field, more particularly to a kind of column with spiral hooping.
Background technology
Bridge pier is the important feature of bridge, and its major function is supporting bridge superstructure, and is made by basis by various
With and dead weight pass to ground.The reinforced concrete pile of round screw thread stirrup has under repeatedly positive and negative repeated load effect
Good ductility and bearing capacity stability, is a kind of preferable structural elements.Under moment of flexure and shearing action, the circular spiral shell in stake
Rotation stirrup has following two effects：Effect of contraction has been deformed to the lateral expansion that curved compressive concrete is produced due to compression,
The stress performance of the compressive region concrete is significantly improved, that is, play the effect of lateral confinement muscle；Play the anti-of resistance shearing
Cut the effect of stirrup.
Application publication number discloses a kind of built-in tie hoop steel-enclosed concrete members for CN103615072A Chinese invention
Post, including sole bar angle, transverse connection, tie hoop, longitudinal reinforcement and core concrete, each angle of post set one
Connected between sole bar angle, sole bar angle with transverse connection, transverse connection is welded in the inner side or outer of sole bar angle flange plate
Side, forms outsourcing steel skeleton, sets longitudinal reinforcement to constitute spiral reinforcement cage in tie hoop inwall, spiral reinforcement cage is placed in outer
Core concrete is filled up in frame center of Baogang, Covered with Angles skeletal internal space.The spiral shell of built-in tie hoop steel-enclosed concrete members post
Rotation stirrup has diametric requirements in selection, but is difficult to turn around curl using the big stirrup of diameter, and uses diameter small
Stirrup then structural strength not enough, specially manufactures diameter suitable stirrup and then can increase quantities again.
Utility model content
The purpose of this utility model is to provide a kind of column with spiral hooping, can meet requirement, the reduction hoop of structural strength
Muscle difficulty, can save the trouble for remanufacturing stirrup again.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of column with spiral hooping, including
Longitudinal reinforcement and concrete bodies, also including tie hoop group, tie hoop group include at least about two it is parallel and be close to arrange
Hoop rib, hoop rib helically structure setting, longitudinal reinforcement is uniformly distributed along the inner ring of hoop rib, longitudinal reinforcement and hoop rib
Form steel reinforcement cage, the inside of concrete bodies filling steel reinforcement cage and the outside for wrapping up steel reinforcement cage.
By using above-mentioned technical proposal, the reinforcing bar as hoop rib be one-level reinforcing bar, that is, wire rod, one-level reinforcing bar
Diameter dimension is not more than 12mm, and single one-level reinforcing bar is used as low intensity during hoop rib, and the reinforcing bar with diameter greater than 12mm is two grades
Reinforcing bar, two grades of reinforcing bars are difficult to turn around into hoop rib, therefore to meet the requirement of structural strength to remanufacture the one of major diameter
Level reinforcing bar, but produce a kind of steel project of diameter again and can increase again.This programme less one-level reinforcing bar of several diameters
Arranged in parallel and be wound in helical structure, in stirrup, the big reinforcing bar of the small reinforcing bar diameter group of diameter is easier curved coiling
Shape；The small reinforcing bar of diameter does not allow frangibility compared with the big reinforcing bar of diameter simultaneously so that pact of the tie hoop group to concrete bodies
Shu Zuoyong can be protected；On the other hand, the reinforcing bar for replacing major diameter with the reinforcing bar of several minor diameters may be omitted with again
Manufacture a kind of trouble of the reinforcing bar of special diameter.Therefore structure can be reached by turning around into helical structure with several one-level parallel reinforced steel bars
Intensity requirement, again will not be because diameter be too big and can not turn around, less with specially going to manufacture a kind of reinforcing bar of special diameter.
It is preferred that, the hoop rib quantity of tie hoop group is 2.
By using above-mentioned technical proposal, hoop rib quantity can reach column with spiral hooping to structural strength from 2
It is required that, the acquisition restriction ability good to concrete bodies and the enhancing to structural strength.
It is preferred that, a diameter of 8mm or 10mm of hoop rib.
By using above-mentioned technical proposal, the diameter dimension of one-level reinforcing bar has 6.5mm, 8mm, 10mm and 12mm, works as use
When two one-level reinforcing bars are as hoop rib, 8mm and 10mm provide enough structural strengths and supported, and have reached stirrup difficulty again
Little requirement.
It is preferred that, the hoop rib quantity of tie hoop group is 3.
By using above-mentioned technical proposal, hoop rib quantity can both reach that the constraint to concrete bodies was made when selecting 3
It is required that, while making stirrup difficulty be maintained in suitable extent and scope again.
It is preferred that, a diameter of 6.5mm or 8mm of hoop rib.
By using above-mentioned technical proposal, compared to two one-level reinforcing bars, three one-level reinforcing bars are main in diameter choosing value
In view of stirrup operation difficulty, therefore the less diameter of selection reduces the performance performance that stirrup difficulty can guarantee that hoop rib again.
It is preferred that, the angle between the initiating terminal and horizontal plane of hoop rib is 5 ° ~ 10 °.
By using above-mentioned technical proposal, model of the angle control at 5 ° ~ 10 ° between the initiating terminal and horizontal plane of hoop rib
In enclosing, it is ensured that tie hoop group possesses enough spiral number of turns, enough number of turns can provide foot for column with spiral hooping
Enough bearing capacitys and structural strength.
It is preferred that, hoop rib is respectively arranged at two ends with one section of connection reinforcing bar parallel to horizontal plane.
By using above-mentioned technical proposal, one section of connection reinforcing bar is set respectively at the two ends of hoop rib, and horizontal plane is to level
The active force that produces of connection reinforcing bar do not result in stress concentration at certain point, therefore the two ends of hoop rib are not easily broken.
It is preferred that, the vertical range d that hoop rib is located between two circles up and down of the same side is 10mm.
By using above-mentioned technical proposal, the vertical range between two circle hoop ribs is 10mm up and down, up and down two circle stirrups
Bar distance both will not be oversize or will not be too short, column with spiral hooping is possessed enough bearing capacitys and structural strength,
Tie hoop group can give play to the effect of contraction to concrete bodies, on the other hand there will not be too big quantities.
It is preferred that, the quantity of longitudinal reinforcement is no less than 4.
By using above-mentioned technical proposal, longitudinal reinforcement has supporting role to tie hoop and concrete bodies, makes spiral
Stirrup and concrete bodies have uniform bearing capacity.
It is preferred that, a diameter of 12mm ~ 16mm of longitudinal reinforcement.
By using above-mentioned technical proposal, longitudinal reinforcement is when in use without bending, therefore in order to ensure its support strength
The reinforcing bar being relatively large in diameter can be selected.
To sum up, a kind of column with spiral hooping described in the utility model, is easier to reach stirrup ratio, and meeting Aseismic Design will
Ask, reduce stirrup difficulty of construction；Without processing the reinforcing bar of special diameter in addition, quantities is reduced；It can possess uniform
Bearing capacity and good shock resistance.
