Abstract

The invention relates to the field of civil engineering, in particular to an adjustable frame column formwork back arris system. The method for building the system is characterized by comprising the steps of 1, determining the number of cycling sets of black laminated timber formworks according to the type of a frame column; 2, determining the size of each steel channel back arris plate, the diameters of openings and the number of the openings according to the size and height of the section of the frame column; 3, determining the distance between vertical steel pipe back arrises according to the size of the section of the frame column; 4, arranging a pull screw with a diameter of 16 mm on each horizontal back arris of the frame column, wherein the distance between the pull screws is identical with that between steel channels; 5, installing a frame column formwork system; 6, pouring concrete onto the frame column; 7, removing the formwork system; 8, reusing the formwork after the formwork is cleaned. According to the system, the adopted technical principle is simple, and operation is convenient; the built formwork system can be reused, construction efficiency is improved, and construction cost is reduced.

Description

technical field

[0001] The invention relates to the field of civil engineering, in particular to an adjustable frame column formwork back corrugated system. Background technique

[0002] Frame columns are widely used in frame structures, frame-shear structures, and frame-tube structures. The setting method of frame column formwork system has an important influence on the geometric dimensions of frame columns and the quality of concrete perception. The common practice of frame column formwork system is to use wood formwork, wooden vertical back flute, steel pipe horizontal back flute and pull bolt system. This method has a large amount of installation and removal of the formwork system, which is time-consuming and labor-intensive, and it is easy to increase the consumption of materials, resulting in waste of materials. Contents of the invention

[0003] The object of the present invention is to provide a formwork back flute system for frame columns that effectively ens...
