Problems solved by technology

The formwork reinforcement of the concealed column of the prefabricated structure generally adopts the drawing die holes reserved on both sides of the PC wall, and the tensioning screws are reinforced. In fact, due to the manufacturing errors of the PC components and the installation errors of the on-site components, the drawing die holes are often not on the same level. Cause back flute can not be installed
At present, there are two main types of L-shaped cast-in-situ cast-in-place formwork for prefabricated structures: 1. Two 50*50*3 square tubes are used as the back flute, which i

Abstract

The invention discloses an adjustable steel back arris for formwork reinforcing of a fabricated L-shaped cast-in-situ embedded column and an implementing method of the adjustable steel back arris, andbelongs to the technical field of supporting and reinforcing of building formworks. The adjustable steel back arris comprises an internal corner back arris assembly and an external corner back arrisassembly, the internal corner back arris assembly comprises a first adjusting back arris component, a second adjusting back arris component and a first connecting component, the first adjusting back arris component and the second adjusting back arris component are detachably connected through the first connecting component, the external corner back arris assembly comprises a third adjusting back arris component, a fourth adjusting back arris component and a second connecting component, the third adjusting back arris component and the fourth adjusting back arris component are detachably connected through the second connecting component, and the first adjusting back arris component, the second adjusting back arris component, the third adjusting back arris component and the fourth adjusting back arris component are all adjusted in the vertical direction. Manufacturing is easy, convenient and economical, operation is convenient, adjustability is realized in the vertical direction, reliability is high, the construction period is shortened, and meanwhile the quality is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of support and reinforcement of building formwork, and in particular relates to an adjustable assembled L-shaped cast-in-place concealed column formwork reinforcement steel back corrugated and an implementation method. Background technique [0002] Assembled structure means that the components are industrially produced in the factory and transported to the site for direct assembly. The components are produced in a standardized manner in the factory to achieve standardized quality, which is conducive to on-site dust and noise reduction, reduces solid waste generation, reduces on-site staffing, reduces turnover material allocation, and achieves on-site green construction. The prefabricated components of the external wall have their own insulation layer, and the construction of the main building does not require traditional external scaffolding. Compared with the traditional cast-in-place structure, it is more ...
