Abstract
The invention discloses a pillar plastic formwork construction method for buildings. The method comprises the following steps of: (1) arranging two plastic pillar external corner formworks at each external corner part in four external corners of a square pillar body bound with reinforcing steel bars in a mutually vertical corner butt joint way, and utilizing profiled clips to connect assembling holes on ribs of the two plastic pillar external corner formworks in a clip connection way; (2) adopting the profiled clips to connect a pillar side formwork between the two plastic pillar external corner formworks located on the same side wall; (3) connecting a plurality of formwork back ridges arranged on plastic formworks on the periphery of the square pillar body along a horizontal direction at intervals; and (4) pouring concrete on the square pillar body. Due to the adoption of the method, the installation efficiency of the formwork is improved, the bearing capacity for the assembled and formed pillar plastic formwork when the pillar body is high in a vertical direction is high, the deformation is not easy to occur, the stability performances are good, the formworks are pieced closely, the safety and the reliability are achieved, and a pillar face can completely achieve an effect of bare concrete.
Description
Technical field
The present invention relates to a kind of plastic formwork job practices, relate in particular to a kind of post of post vertical height when higher of building with the job practices of plastic formwork.
Background technology
Construction formwork is a kind of temporary structure, and it is made by designing requirement, and concrete structure, member position, physical dimension in accordance with regulations is shaped, and keeps its tram, and bears construction formwork deadweight and effect load thereon.And construction formwork is the important tool of concrete structure engineering construction.The expert points out that in Cast-in-situ Concrete Structural Engineering, form work engineering generally accounts for 20%～30% of concrete structure engineering cost, accounts for 30%～40% of the engineering amount of labour used, accounts for about 50% of the duration.Mould plate technique directly affects quality, cost and the benefit of engineering construction, so it is an important content that promotes China's Building technology progress.Plastic formwork is a kind of New Type Architecture Mode in construction formwork, can replace traditional steel form, wooden form, the lumps of wood fully.Can repeatedly have enough to meet the need use, energy-conserving and environment-protective.
