Description
Technical field
A kind of performance of concrete column confined manufacturing technology is the utility model is related to, more particularly to it is a kind of for making square column type concrete
The template free of demolition of pier stud.
Background technology
Columnar pier is bridge pier form widely used in current highway bridge；Prior art when making columnar pier,
Pier shaft reinforcing bar and column template are typically built on cushion cap, column template is located at the periphery of pier shaft reinforcing bar, finally by column template
Casting concrete forms bridge pier, after bridge pier shaping, then column template is removed；The problem of existing has：1) common column template one
As be plank sheathing or steel form, plank sheathing is easily damaged in work progress, in work progress may need repeatedly change, punching block
Easily there is corrosion to plate in part under water, can not reuse, spillage of material is larger；2) conventional column template needs to be segmented section by section
Assembly, easily there is defective mounting, cause Construction Joint and deformation crack, if piece is not also easy to spillage situation occur sternly；
3) after after column template is removed, bridge pier surface piece vestige is more, influences pier shaft quality and attractive in appearance, therefore column template is removed, generally
Also moditied processing is carried out to pier shaft surface, it is more troublesome；4) in columnar pier engineering, column template build and dismantling operation all
Relatively complicated, the amount of labour used of occupancy and duration are all more.Generally speaking, existing column template installation, dismounting are all more troublesome, apply
The work cycle is longer, the problems such as pier shaft surface crack easily occurs.
Utility model content
The problem of in background technology, it is used to make exempting from for square column type performance of concrete column confined the utility model proposes a kind of
Template is dismantled, its structure is：The template free of demolition is made up of framework of steel reinforcement, multiple pegs and concrete covering；The reinforcing bar
Skeleton is tubular structure body, and the cross section of tubular structure body is rectangle, and framework of steel reinforcement is wrapped in interior, reinforcing bar by concrete covering
Frame and concrete covering form the tubular reinforced concrete structure that cross section is rectangle；One end of the peg and the reinforcing bar
Frame is fixedly connected, and the other end of peg is prominent from the inner hole wall of the tubular reinforced concrete structure, the exposed segment length of peg
Radial dimension of the degree much smaller than tubular reinforced concrete structure；Multiple pegs are equal on the inner hole wall of tubular reinforced concrete structure
Even distribution.
After the utility model, template free of demolition can pre-production be good in factory, is then transported to job site again；
During construction, template free of demolition is hoisted to above cushion cap, template lower end free of demolition is connected with cushion cap, in template free of demolition and cushion cap
Pier core reinforcing bar is built in enclosed space and (reinforcing bar inside pier stud is typically referred to as pier shaft reinforcing bar in the prior art, in this programme
In, due to set template free of demolition in outside, therefore the reinforcing bar of inside is referred to as pier core reinforcing bar by inventor), then to free of demolition
The endoporus concrete perfusion of template, after pouring, the pier core reinforcing bar and the concrete that newly pours of template free of demolition and its inside are total to
With formation pier stud；Intensive uniform peg can effectively improve template free of demolition and inner concrete as shear connector
Being completely embedded property, improve the stress globality of the armored concrete newly poured and template free of demolition.After the utility model, exempt from
Dismantle template can the pre-production in factory, built without scene, it is more convenient to make, and cost of manufacture is relatively low, and construction is completed
Afterwards, template free of demolition forms a part for pier stud, without removing, can greatly simplify pier stud constructing operation, shorten the duration, this
Outside, the outer wall of template free of demolition just can carry out moditied processing in the lump when making, and the bridge pier produced is repaiied without carrying out surface again
Decorations, it is more convenient, while seam and spillage problem caused by template splicing can also be avoided.
Preferably, the framework of steel reinforcement is made up of a plurality of side's steel hoop and a plurality of vertical bar shaped reinforcing bar；Side's annular steel
Muscle and the tubular structure body are coaxial, and a plurality of side's steel hoop is axially distributed along tubular structure body；The axle of the vertical bar shaped reinforcing bar
To axially in parallel with tubular structure body, wall scroll vertical bar shaped reinforcing bar is fixedly connected with a plurality of side's steel hoop, a plurality of vertical bar shaped steel
Muscle is circumferentially distributed along tubular structure body.Specific reinforcement manner and rebar sizes and concrete grade, people in the art
Member can rationally determine according to existing reinforced concrete structure strength design theory.
Preferably, the upper and lower ends of the template free of demolition are provided with reserving rib.The reserving rib be used for cushion cap and
Embedded ribs connection on bent cap.
Preferably, the concrete covering is using more than compression strength 120MPa, more than rupture strength 30MPa superelevation
Energy concrete (UHPC) makes, and makes concrete covering using this concrete, can effectively reduce the radial direction of template free of demolition
Thickness and weight, it is readily transported and installs.It is recommended that the match ratio of various composition can use following preferred scheme in concrete：Water
Ni ︰ Gui Hui ︰ Shi Ying Sha ︰ Shi Ying Fen ︰ Jian Shui Ji ︰ water=1:0.25:1.1:0.3:0.019:0.225, and 2% is mixed with upper volume
Steel fibre.
Advantageous effects of the present utility model are：Provide a kind of for making the free of demolition of square column type performance of concrete column confined
Template, after this template free of demolition, it can significantly simplify Bridge Pier Construction operation, reduce construction cost, improve construction quality.
