Non-back-ridge built-up type all-steel big shuttering

Abstract

The invention relates to a non-backridge repetitive all-steel large formwork, which comprises a panel, frames and support ribs, wherein, the frame has a ridge and fold bends in the middle and the cross section of the frame is of a brace shape; four frames form a rectangular framework; the support ribs have a plurality of pieces and are arranged between the two long frames of the rectangular framework equidistantly; both ends of each support rib is fixedly and respectively connected with the two long frames; the panel is arranged on one side of the rectangular framework and the support rib andis fixed with the rectangular framework and the support rib by rational intermittent welding. The formwork has the advantages that the overall strength and stiffness of the formwork are reliable, thestructure is simple, the assembly is fast, the joints are free from dislocation, the jointing is compact, leakage is not easy to occur. In addition, the formwork achieves the effect of good rinsing on the surface of the concrete and mobile use times the same as the backridge repetitive all-steel large formwork, facilitates to arrange regular decoration strips on the surface of the concrete and meets the requirement of open joint decoration on the surface of the concrete wall.

Description

technical field The invention relates to an assembled all-steel large formwork, in particular to an assembled all-steel large formwork without back corrugation, which belongs to the field of building formwork. Background technique In modern construction engineering, there are mainly two types of concrete wall formwork, one is the large all-steel formwork with back corrugated assembly, which is mainly used in domestic projects; the other is wood formwork with no back corrugated steel frame, which is mainly used in foreign projects and domestic requirements Concrete works with advanced clean water effect. However, as modern large-scale venues and some buildings are developing toward new, strange, and special diversifications, clear water projects with decorative strips continue to increase. The existing formwork varieties can meet the design requirements in terms of clear water effects, but there are problems in combining the performance of decorative strips. Serious defects,...

Problems solved by technology

However, as modern large-scale venues and some buildings are developing toward new, strange, and special diversifications, clear water projects with decorative strips continue to increase. The existing formwork varieties can meet the design requirements in terms of clear water effects, but there are problems in combining the performance of decorative strips. Serious flaws, difficult to achieve design requirements

In addition, the assembled all-steel large formwork with back corrugated is suitable for engineering configuration, and it is troublesome to disassemble and reassemble. It must be carried out by a professional formwork company, and the construction unit cannot configure it by itself; The party requires a new type of formwork that can be conveniently configured by the construction party. There is no concrete wall formwork that can meet the requirements of these two aspects at the same time.
