Adjustable Assembled L-shaped Cast-in-place Concealed Column Formwork Reinforcement Steel Back Corrugation and Its Implementing Method

Abstract

The invention discloses an adjustable assembled L-shaped cast-in-situ cast-in-place formwork steel back corrugated for reinforcement and an implementation method, belonging to the technical field of building formwork support and reinforcement. It includes the inner corner back flute assembly and the male corner back flute assembly, the inner corner back flute assembly includes a first adjustment back flute assembly, a second adjustment back flute assembly and a first connection assembly, the first adjustment back flute assembly The assembly and the second adjustment back flute assembly are detachably connected through a first connection assembly, and the male corner back flute assembly includes a third adjustment back flute assembly, a fourth adjustment back flute assembly and a second connection assembly, and the third adjustment The back flute assembly and the fourth adjustment back flute assembly are detachably connected through the second connection assembly, and the first adjustment back flute assembly, the second adjustment back flute assembly, the third adjustment back flute assembly and the fourth adjustment back flute assembly are all Vertical adjustment. The production is simple and economical, the operation is convenient, the vertical direction can be adjusted, the reliability is high, the construction period is saved, and the quality is guaranteed at the same time.

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 ...

AI Technical Summary

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 is too heavy and difficult to operate; 2. Angle steel welded back flute , to weld the upper and lower parts of the angle steel together, it is required that the pull screws must be on the same level, but in the actual construction process, it is limited by factors such as the processing accuracy and installation accuracy of the prefabricated components, it is difficult to ensure that the screw holes are at the same height, which is As a result, partial back corrugation cannot be installed, resulting in on-site processing such as opening holes, which affects the quality of the project
