Change the status quo, the form work engineering amount of job site should be reduced.Prior art has employing prefabricated reinforced concrete hollow column template to make reinforced column, be provided with inside this column template along longitudinally through one or more hollow tunnel；Although using this technology to decrease the form work engineering amount of job site, but the rear pouring concrete in pillar being separated by the precast concrete between hollow tunnel, affects the globality of pillar, and then affects its stress performance.
Summary of the invention
The invention provides the manufacture method of a kind of prefabricated reinforced concrete hollow column template.
The present invention proposes the manufacture method of prefabricated reinforced concrete hollow column template, and described column template is provided with many limbs stirrup, be internally provided with one longitudinally through hollow tunnel, part stirrup pass described hollow tunnel；Described manufacture method comprises the following steps: that (1) assembles the column template being made up of external mold and multiple interior mould, and configuration reinforcement skeleton；Described interior mould includes rigid member and the flexible piece of parcel rigid member at center, is arranged in the region that stirrup surrounds, and interior mould fits together；(2) in the space that column template is formed, concrete, vibration compacting are injected；(3) rigid member of mould in extracting out before concrete final set or after final set, then extract the flexible piece formation hollow tunnel of interior mould out；(4) remove external mold and form prefabricated reinforced concrete hollow column template.Described rigid member can use metal or fibre reinforced composites or timber etc. to make, and described flexible piece can use rubber etc. to make.Stirrup by outer wall drawknot together, improves rigidity and the intensity of outer wall, and strengthens outer wall precast concrete and the globality of the rear pouring concrete poured in column template.The thickness of column template outer wall requires to determine according to making, construction, stress etc..When the hollow tunnel of described prefabricated reinforced concrete hollow column template is circular cross-section, centrifuging is used to make；Centrifuging is currently used for making pile tube etc., technology maturation, can be used for making the column template of the present invention.
Described prefabricated reinforced concrete hollow column template outer wall has split bolt hole, and rise during by arranging split bolt and can prevent casting concrete in column template mould.
The cross-sectional profile of described prefabricated reinforced concrete hollow column template is square or circular or L-shaped or T-shaped or cross or polygon etc..
In described prefabricated reinforced concrete hollow column template, the drift angle of hollow tunnel is arc chord angle or chamfering.
The surface of the hollow tunnel of described prefabricated reinforced concrete hollow column template is matsurface, can increase the globality between precast concrete and rear pouring concrete.
In described prefabricated reinforced concrete hollow column template outer wall, vertical muscle is set.
Feature and the effect of the present invention include:
(1) the prefabricated reinforced concrete hollow column template of the present invention is factorial praluction, and production efficiency is high, quality is good, substantially reduce work on the spot amount, can improve the industrialized level of building structure, saves resource, the energy, beneficially sustainable development.
(2) use the prefabricated reinforced concrete hollow column template of the present invention can substantially reduce the labor intensity of job site, reduce time and manpower consumption.All or part of reinforcing bar of post is placed in prefabricated reinforced concrete hollow column template, substantially reduces the workload of job site；Column template can greatly reduce the workload of job site template, support；The outside flatness of column template is good, and the construction quality of pillar is easily guaranteed that, and can cancel post surface plastering etc..
(3) lateral tie of the prefabricated reinforced concrete hollow column template of the present invention passes hollow tunnel, can improve the strength and stiffness of column template, strengthens the globality of outer wall precast concrete and the rear pouring concrete poured in column template；Rear pouring concrete in column template is an entirety, the pillar good integrity made.
(4) mould in the prefabricated reinforced concrete hollow column template manufacture method that the present invention proposes is extracted out after concrete final set, it is to avoid damage hollow tunnel hole wall concrete, it is ensured that hole quality；And rough hole wall can be formed, water the globality of the concrete in hollow tunnel and precast concrete after raising.
