Formwork reinforcing system replacing wood with steel and construction technology thereof in external wall construction

Abstract

The invention belongs to the field of building construction, and provides a formwork reinforcing system replacing wood with steel and a construction technology thereof in external wall construction. The formwork reinforcing system replacing the wood with the steel is characterized in that a steel keel support assembly is arranged on a concrete structural wall body and composed of vertical battens and horizontal battens, the vertical battens are fixed to waterproof-bolt holes in the uppermost row of the two sides of the concrete structural wall body, the horizontal battens are horizontally arranged on the vertical battens, vertical keels are perpendicularly arranged on the horizontal battens, and the vertical keels are fixedly connected with a wooden formwork through steel nails. The construction technology of the formwork reinforcing system replacing the wood with the steel comprises the following steps of scaffold erection, aerial supporting construction of the external wall vertical steel keels, seam splicing construction of an external wall formwork, steel keel installation construction and external wall reinforcing construction. According to the formwork reinforcing system replacing the wood with the steel and the construction technology thereof in the external wall construction, the technology is simple, operation is convenient, and the construction problem existing in an existing construction technology is effectively solved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a construction process of a formwork reinforcement system using steel instead of wood in the construction of an external wall in the construction of a cast-in-place concrete structure. Background technique [0002] At present, with the gradual scarcity of wood resources, the country pays more and more attention to the use of low-carbon, environmentally friendly, renewable and recyclable new materials, and the construction field is also one of the high energy-consuming industries. Green construction is already a new normal. The construction of cast-in-place concrete structures in China has become more common. In the construction of cast-in-place structures, the traditional formwork reinforcement system mostly uses wooden squares as the secondary keel. In recent years, because the mechanical properties of steel pipes are far superior to traditional wooden squares, ...

AI Technical Summary

Problems solved by technology

In recent years, because the mechanical properties of steel pipes are far superior to traditional wooden squares, workers can prevent workers from cutting at will during construction, and construction costs can be effectively controlled. Therefore, the construction concept of replacing wood with steel has been increasingly adopted by most construction units, but However, there are several construction problems in the construction of square steel pipes: the weight of square steel pipes is relatively large, especially in the construction of some ultra-high external walls, the vertical weight of steel pipes is much greater than that of wooden squares, and it cannot be suspended in the air; square steel pipes and wood glue The traditional technique of driving iron nails cannot be used to fix the connection between the boards; the steel pipes in the super high and super long parts cannot be lengthened at will and other construction technical problems
