Construction method of assembling high turnover rate steel-coated plywood lightweight formwork system

Abstract

The invention discloses a construction method of an assembling high turnover rate steel-coated plywood lightweight formwork system. The construction method comprises the following steps of formwork design, formwork preparation, panel coating, formwork installation, correction reinforcement and formwork removing, wherein the step of formwork design is design of standard formworks, non-standard formworks, external corner formworks and internal corner formworks. The construction method has the advantages of flexible assembly, good impression quality, fast construction progress and high turnover rate.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and construction engineering, and in particular relates to a construction method for an assembleable high-turnover section steel-film-coated plywood lightweight formwork system. Background technique [0002] Formwork is the forming mold for pouring concrete in building construction. It is an important part of cast-in-place concrete structure engineering. Traditional formwork includes wood formwork, bamboo formwork, steel formwork, plastic formwork, cast aluminum alloy formwork, etc. Due to material limitations, single material formwork Formwork has its own disadvantages, such as high one-time investment cost of large steel formwork, long time of tower crane occupation, vertical structure and horizontal structure cannot be constructed at the same time, small steel formwork has small single block area, many joints, poor visual quality, and poor construction quality. Slow speed, single-piec...

[0002] Formwork is the forming mold for pouring concrete in building construction. It is an important part of cast-in-place concrete structure engineering. Traditional formwork includes wood formwork, bamboo formwork, steel formwork, plastic formwork, cast aluminum alloy formwork, etc. Due to material limitations, single material formwork Formwork has its own disadvantages, such as high one-time investment cost of large steel formwork, long time of tower crane occupation, vertical structure and horizontal structure cannot be constructed at the same time, small steel formwork has small single block area, many joints, poor visual quality, and poor construction quality. Slow speed, single-piece assembled wooden formwork, less turnover times, poor rigidity, and poor operability, the strength and rigidity of plastic building formwork are too small, and the cost of aluminum alloy formwork is relatively high. Therefore, people gradually realize the necessity of using combined formwork. Formwork has the advantages of high manufacturing precision, high combination rigidity, and long service life. However, the splicing and construction of traditional combination formwork is more complicated, the assembly speed is slow, disassembly is difficult, and the turnover rate is low. With the implementation of the national green and environmental protection construction concept, it is urgent to adopt New combination template technology to solve the above problems
