Plastering-free curved concrete wall section steel back rib composite template and construction method

Abstract

The invention discloses a plastering-free curved concrete wall section steel back rib composite template and a construction method. The plastering-free curved concrete wall section steel back rib composite template comprises split bolts, steel pipe key keels, shaped channel steel, a wood glue boards, square pillars and galvanized iron sheets. The galvanized iron sheets are arranged between the curved concrete wall and the wood glue boards, and the wood glue boards are internally coated with the galvanized iron sheets. Two ends of the split bolts which penetrate through the curved concrete wallsequentially penetrate through the galvanized iron sheets, the wood glue boards, the shaped channel steel and the steel pipe key keels to be connected with nuts through threads. The construction method comprises the steps of positioning and paying off, shaped template manufacturing, reinforcing steel binding and concealed check acceptance, template assembling, template reinforcement, concrete pouring, form removal and maintenance. According to the plastering-free curved concrete wall section steel back rib composite template and the construction method, the template is completed and concreteis poured in the middle, so that the concrete structure is positioned accurately, the molding quality is good, the surface does not need to be plastered, and the operation is simple and easy; and theparts are subjected to batch processing, the construction speed is higher, the cost is low, the construction requirements can be met, and the economical and practical property is achieved.

Description

technical field [0001] The invention relates to a building construction method, in particular to a plaster-free curved concrete wall-shaped steel-back corrugated composite template and a construction method. Background technique [0002] With the continuous increase of architectural shapes, more and more curved concrete cast-in-situ walls are used in projects. Such walls are usually designed with fair-faced concrete without a plastering surface layer. The formwork requires high precision and difficult construction. If the finished shaped steel mold is used, the cost is high and the processing cycle is long; if the sliding form is used, it is not suitable for projects with small building heights, and the cost is extremely high. Therefore, there are defects in the above traditional formwork methods.
