Reinforcement Method of Secondary Structural Columns

Abstract

The invention discloses a secondary structure column reinforcing method. The method comprises the steps that a structure column center line and an elevation control line are snapped; structure column bars are bound; an opposite-pull threaded rod and a wall horizontal tying bar are welded; a T-shaped locating steel bar is welded to the portion, 5 cm away from the root of a structure column, of a structure column main bar, and the section and axis position of the structure column are controlled; a wide sponge strip is pasted to the position about 5 mm away from the outer side of the skin of the structure column; a structure column formwork is mounted; a structure column hoop is mounted; the structure column formwork is corrected and reinforced; column concrete is poured; the formwork is detached, the portion, stretching out, of the threaded rod is cut off along the surface of the structure column, and the cut-off end of the threaded rod is subjected to antirust treatment. According to the method, the wall horizontal tying bar and the wall-penetrating opposite-pull threaded rod of the structure column are welded, the threaded rod is combined with a butterfly clasp to lock a steel tube for reinforcing a batten back edge at the end of the structure column, the pull force of the horizontal bar is utilized for providing horizontal constraint required for reinforcing the end of the structure column, and therefore stability is higher; the defect that a masonry structure causes reduction of wall integrity and compressive strength due to structure column formwork perforation is overcome.

Description

technical field [0001] The invention relates to the fields of building construction and secondary structure construction, in particular to a method for reinforcing structural columns of a secondary structure. Background technique [0002] In the current construction industry, the masonry structure needs to add structural columns to enhance the integrity of the masonry. The formwork reinforcement of the structural columns mainly adopts the traditional method of punching holes on the masonry structure and combining wooden corrugated and steel pipe reinforcement formwork. The disadvantage is that drilling holes in the masonry wall will destroy the integrity and compressive strength of the masonry structure, reduce the stability of the wall, and cause hollowing, cracks and other quality defects in the subsequent plastering process. [0003] Reference document 1 with the application number 201420504673.6 discloses a structural column formwork block. The structural column formwork...
