Abstract

The invention discloses a steel formwork and a manufacturing method thereof. The steel formwork comprises first L-shaped steel supporting formworks and second L-shaped steel supporting formworks whichare the same in structure and size, and each first L-shaped steel supporting formwork sequentially comprises an L-shaped steel face plate, a secondary rib layer, a primary rib layer and a reinforcinglayer from inside to outside. The manufacturing method comprises the steps that first, the specifications of the steel formwork are planned; second, the total load borne by the steel formwork is obtained; third, the design deformation amount of the steel formwork is calculated; fourth, a finite element model of the steel formwork is established, and the strength and the deflection of the steel formwork are verified; and fifth, the steel formwork is manufactured. The steel formwork with the four sealed walls is formed by the first L-shaped steel supporting formworks and the second L-shaped steel supporting formworks in an assembled mode, the steel formwork is fastened to the connection positions of the first L-shaped steel supporting formworks and the second L-shaped steel supporting formworks through a plurality of tie bars, through design of double L-shaped transverse pressure-bearing plates, the self weight of the steel formwork is decreased while the lateral pressure is ensured, and a gap between the L-shaped transverse pressure-bearing plates allows the tie bars to be inserted.

Description

technical field

[0001] The invention belongs to the technical field of steel formwork, and in particular relates to a steel formwork and a manufacturing method thereof. Background technique

[0002] With the development of my country's economy, there are more and more large-scale industrial plants and logistics warehouses in engineering construction, and more steel structures, PC, and cast-in-place concrete composite structures are used. The cast-in-place concrete columns are used as the main load-bearing columns, and the speed of on-site fabrication becomes a constraint The key to the installation of PC components and roof trusses. The traditional construction techniques of scaffolding, formwork and concrete pouring are no longer suitable for the construction of large industrial plants and logistics warehouses. Traditional cast-in-place column construction requires erection of operational scaffolding, steel bar binding, formwork support, etc. to be completed at the construc...
