Abstract

The invention provides a structural reinforcing construction method. The structural reinforcing construction method comprises the following steps of removing decoration layers of a frame column and astructural beam; arranging steel angles at the four corners of the frame column, adjusting the perpendicularity of the steel angles and uniformly welding a plurality of short flat steels between the two adjacent steel angles; arranging a plurality of U-shaped flat steels on the structural beam in a sleeved mode; and connecting the U-shaped flat steels into a whole through long flat steels; and filling structural adhesives and conducting plastering construction on the frame column and the structural beam. The four steel angles are wrapped outside the frame column, so that the bearing capacity of a steel structure is high, the bearing capacity and ductility of the stand column to an inner floor slab are improved, and the bearing capacity and durability are improved. The two ends of the shortflat steels are welded to the steel angles at intervals in sequence, and the integrity and bearing capacity of the whole structure are improved. The flat steels are fixed to an original frame columnthrough anchor bolts for anchoring construction, and the strength, stiffness and stability of a column body are improved. The section steel surface is subjected to anticorrosion and shot blasting treatment to prevent the steel structure from being corroded, and the service life of the reinforced structure is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a structure reinforcement construction method. Background technique [0002] At present, in the frame structure, concrete beams and columns, as the main force-bearing components, play an important role in bearing and transmitting loads, and are important components that affect the collapse and damage of building structures, and their safety directly determines the safety performance of the entire concrete structure . Due to the influence of man-made or natural disaster factors such as construction and reconstruction projects, poor construction quality, long test time, structural overload, fatigue load, and structural performance degradation caused by steel bar corrosion in erosive environments, the building structure is extremely vulnerable to moderate and large earthquakes. Collapse and damage caused loss of people's property safety. Therefore, in order to prolon...
