Abstract

The invention provides a construction method of a high-precision formwork of a cast-in-place fair-faced concrete wind tunnel. The construction method comprises the steps of typesetting and setting out, formwork machining, steel frame welding and flatness adjusting, scaffold building, formwork mounting, high-precision formwork system checking, concrete pouring and the like. According to the construction method of the high-precision formwork of the cast-in-place fair-faced concrete wind tunnel, typesetting analysis is performed by establishing a model, the formwork precision is high, formwork system reinforcing measures are complete, and the situation that deformation is avoided in the pouring process can be guaranteed; besides, the formwork assembling degree is high, an extremely high assembling degree is achieved in a creeping formwork system and a steel frame wood formwork system, the field construction difficulty is low, and the assembling speed is greatly increased while the precision is guaranteed; and the detection and mounting process is implemented in the construction process, adjustment can be made immediately once mounting deviation is found, and the problem that an existing fair-faced concrete construction technology is poor in control precision is solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for a high-precision formwork in a wind tunnel of cast-in-place fair-faced concrete. Background technique [0002] With the vigorous development of the construction industry, more and more iconic buildings are designed and constructed using fair-faced concrete. Fair-faced concrete is an expression of architectural modernism. It is also called decorative concrete because of its great decorative effect. Finally, there is no longer any painting, tiling, stone and other materials to express a kind of bare-faced technique of concrete. At present, the fair-faced concrete construction technology in the industry only meets the appearance effect requirements, and its precision control is poor. Contents of the invention [0003] The embodiment of the present invention provides a high-precision formwork construction method for a cast-in-place fair-fa...
