Construction method of rapid formwork support for cylindrical hoop-type paired wood formwork

Abstract

The invention relates to a quick formwork construction method for a cylindrical strap type butt splicing wooden template and belongs to the technical field of a building construction method. The method comprises the following steps: positioning an elastic column; placing a slurry blocking base plate; leveling the range of a cylindrical mold; placing a reinforcing steel bar cushion block; checking and accepting concealed engineering; mounting a cylindrical template; segmentally adjusting the verticality of the template; segmentally fixing hoops; supporting and strengthening the cylindrical template; blocking slurry at the root part; pre-checking; pouring concrete; cleaning the root; and detaching the mould. By the technology, concavo-convex rabbets are formed on the sides of two semi-circular wooden plates of the cylindrical strap type butt splicing wooden template; special construction machinery and equipment are not needed in the construction process; when the templates are spliced, a fixed hoop and a locking bolt are directly used for reinforcing; assembling and disassembling are convenient; the surface does not have bolt holes; the appearance quality of concrete is greatly improved; the obtained cylinder has smooth surface; the comprehensive effects of good impression, low manufacturing cost, high precision, simple and convenient construction and the like are achieved; and the method is suitable for construction of reinforced concrete independent cylinders of industrial and civil buildings and municipal bridge engineering.

Description

technical field [0001] The invention belongs to the technical field of building construction methods, and in particular relates to a construction method for rapid formwork support of cylindrical hoop-type paired wood formwork with flexible assembly and convenient construction. Background technique [0002] The traditional concrete cylindrical formwork generally has the following types: it is made of circular arcs made of wooden strips or piece-by-piece welding of steel plates or made of glass fiber reinforced plastics; the steel cylindrical formwork is installed in sections with flanges, so There are many joint marks on the surface of the obtained concrete column, and the size of the steel formwork is relatively conventional, and the self-heavyness makes it difficult to process and splice on-site, the custom processing time is long, and the use cost is high; the concrete surface of the conventional splicing formwork with wooden strips is not smooth Not supple, labor-intensiv...

[0002] The traditional concrete cylindrical formwork generally has the following types: it is made of circular arcs made of wooden strips or piece-by-piece welding of steel plates or made of glass fiber reinforced plastics; the steel cylindrical formwork is installed in sections with flanges, so There are many joint marks on the surface of the obtained concrete column, and the size of the steel formwork is relatively conventional, and the self-heavyness makes it difficult to process and splice on-site, the custom processing time is long, and the use cost is high; the concrete surface of the conventional splicing formwork with wooden strips is not smooth Not supple, labor-intensive, time-consuming, and material-intensive; while the FRP cylindrical formwork can make the concrete appearance round and smooth, and the quality is good, but the operation technology requirements are high, and the formwork cleaning and maintenance requirements are high, and a little improperness will easily affect the service life
