Adjustable arc building wood formwork

Abstract

The invention relates to an adjustable arc building wood formwork. The adjustable arc building wood formwork comprises a plurality of adjusting supports and wood formwork bodies, wherein the adjustingsupports are sequentially connected end to end, and the wood formwork bodies are placed on the adjusting supports; each adjusting support comprises a back ridge and two adjusting pieces; the two adjusting pieces are fixedly arranged on the two sides of the back ridge correspondingly; each adjusting piece comprises two adjusting plates; the two adjusting plates are fixed to one side of the back ridge in parallel and provided with a first hinge hole and a second hinge hole correspondingly; the two adjusting plates in one adjusting support are clamped in the two adjusting plates in the other adjusting support, and the two adjusting supports are connected through a first hinge shaft inserted in the first hinge hole; second hinge shafts are arranged in the second hinge holes; each second hingeshaft is detachably provided with a fixing base; each fixing base is provided with a threaded hole; and a lead screw sleeved with a nut is connected between the threaded hole in one adjusting supportand the threaded hole in the other adjusting support. The purposes that the structure is simple, and the angle between every two connected formwork bodies can be adjusted in a stepless manner are achieved.

Description

technical field [0001] The invention relates to the field of formwork, in particular to an adjustable form circular arc building wooden formwork. Background technique [0002] Highway bridges are built for the passage of vehicles on elevated highways. Highway bridges are made of steel, reinforced concrete or wood. With the rapid development of bridge construction, steel-concrete bridge beams are not uncommon. The formwork is the main component of the steel-concrete bridge beam, and the formwork becomes an important component in the construction of the steel-concrete bridge. Since most parts of the expressway have been turned over, the formwork to be built sometimes needs to present a certain angle, and the existing technology needs to add adjustment components to adjust the angle between two adjacent formwork, while the traditional The structure of the adjustment assembly in the fuselage is complex and cannot achieve the purpose of infinitely adjusting the angle. Therefore...

AI Technical Summary

Problems solved by technology

Due to the fact that most parts of the expressway have been completed, the templates that need to be built sometimes need to present a certain angle, but in the existing technology, adjustment components need to be added to adjust the angle between two adjacent templates, while the traditional The structure of the adjustment components in the device is complicated, and the purpose of stepless adjustment of the angle cannot be achieved. Therefore, a device is urgently needed to solve the existing problems
