The prefabricated reinforced concrete open tubular column template outer wall split bolt hole the utility model proposes, by arranging the mould that rises when split bolt can prevent in column template casting concrete.
The cross-sectional profile of the prefabricated reinforced concrete open tubular column template the utility model proposes is square circular or L shaped or T shape or cross or polygon etc.
In the prefabricated reinforced concrete open tubular column template the utility model proposes, the drift angle in hollow duct is arc chord angle or chamfering.
The surface in the hollow duct of the prefabricated reinforced concrete open tubular column template the utility model proposes is matsurface, can increase the globality between precast concrete and rear pouring concrete.
In the prefabricated reinforced concrete open tubular column template outer wall that invention proposes, vertical muscle is set.
The preparation method of prefabricated reinforced concrete open tubular column template, comprises the following steps:
(1) column template that assembling is comprised of external mold and a plurality of internal mold, configuration stirrup and vertical muscle; Described internal mold comprises the rigid member at center and the flexible piece of parcel rigid member, is arranged in the region that stirrup surrounds; Stirrup through hollow duct is divided into several regions by pillar, and an internal mold is set in each region, and each internal mold fits together.Can the good stirrup of first colligation and vertical muscle, then internal mold is penetrated to the region that stirrup surrounds; Described rigid member adopts metal or fibre reinforced composites or timber etc. to make, and described flexible piece adopts rubber to make; .
(2) in the space forming at column template, inject concrete, vibration compacting; .
(3) before concrete final set or extract the rigid member of internal mold after final set out, then the flexible piece of extracting internal mold out forms hollow duct; .
(4) remove external mold and form prefabricated reinforced concrete open tubular column template.
Feature of the present utility model and effect comprise:.
(1) prefabricated reinforced concrete open tubular column template of the present utility model is that batch production is produced, and production efficiency is high, quality good, significantly reduce work on the spot amount, can improve the industrialized level of building structure, and saving resource, the energy, be conducive to sustainable development.
(2) adopt prefabricated reinforced concrete open tubular column template of the present utility model can significantly reduce the labour intensity of job site, minimizing time and manpower consumption.The all or part of reinforcing bar of post is placed in prefabricated reinforced concrete open tubular column template, significantly 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 easily guarantees, and can cancel post surface plastering etc.
(3) lateral tie of prefabricated reinforced concrete open tubular column template of the present utility model, through hollow duct, can improve the strength and stiffness of column template, strengthens outer wall precast concrete and the globality of building the rear pouring concrete in column template; Rear pouring concrete in column template is an integral body, the pillar good integrity of making.
