Dorsal bar system

Abstract

The invention discloses a dorsal bar system. The dorsal bar system comprises a plurality of dorsal bar single bodies, a plurality of U-shaped fixtures, a plurality of large internal corner connectors,a plurality of small internal corner connectors and a plurality of external corner connectors; and the dorsal bar single bodies comprise rectangular pipes, and at least one I-shaped structural memberis installed on the pipe wall of each rectangular pipe. The dorsal bar rectangular pipes use 300 as the modulus, and have a length of 300 / 600 / 900-3000 and other specifications. The rectangular pipescan be used alone or in combination to meet the requirements of different formworks; welding is almost not required in the machining process, after the pipes are cut, the dorsal bar system can be usedthrough combination of the U-shaped fixtures, the internal corner connectors, the external corner connectors and other connecting pieces, for internal corner and external corner position connection,fixed angle parts and diagonal draw rods are mounted, and the angle can be adjusted to ensure the 90-degree right angle forming requirements; and according to the cost, the novel dorsal bar system saves the cost of refurbishment during secondary use, almost no waste or customized part exists, and after cleaning and counting, the materials can be combined again for the next project.

Description

technical field [0001] The invention belongs to the technical field of formwork building construction, and in particular relates to a corrugated backing system. Background technique [0002] The back corrugated system is one of the building formwork systems. Its main function is to fasten the formwork and prevent deformation as a support system to ensure the molding quality and size of the building. The traditional back flutes include wooden square back flutes (the back flutes are connected by nails), round steel pipe back flutes (the back flutes are connected by buckles), square tube back flutes (the back flutes are connected by welding), back flute It is usually fixedly connected with the formwork by through-wall bolts. Square tube corrugation is the latest practice in the market in recent years. Square tube corrugation is mainly combined with aluminum alloy formwork, and other wood formwork and steel formwork are also gradually being used. The original square tube back ...

AI Technical Summary

Problems solved by technology

The original square tube back flute is made by design, cutting and welding. The production is basically the same as that of the formwork. Its utilization rate is low, the loss is large, and the loss rate is more than 30%, and the construction convenience is not very good.
