Assembly type oblique stiffening thin-walled steel plate shear wall reinforcing structure and construction method thereof

Abstract

The invention provides an assembly type oblique stiffening thin-walled steel plate shear wall reinforcing structure and a construction method thereof, and relates to the technical field of building reinforcement. The assembly type oblique stiffening thin-walled steel plate shear wall reinforcing structure comprises a thin-walled steel plate arranged on the inner side of an RC frame, the outer edgeof the thin-walled steel plate is connected with the RC frame through a light steel constraint frame, the inner edge of the thin-walled steel plate is connected with a tension ring, a plurality of oblique stiffening ribs which can be slidably connected through bolts are arranged between the light steel constraint frame and the tension ring, a plurality of dividing lines extending along the oblique stiffening ribs divide the thin-walled steel plate into a plurality of thin-walled special-shaped steel plate blocks constrained by the oblique stiffening ribs, and the side edges, close to the dividing lines, of the thin-walled special-shaped steel plate blocks are connected with the oblique stiffening ribs; and the tension ring comprises a reinforcing outer ring, first reinforcing pieces are distributed and connected along the periphery of the reinforcing outer ring, and second reinforcing pieces are connected to the inner side of the reinforcing outer ring. The problems that a building reinforcing structure in the prior art is large in influence, long in construction period, large in wet operation face and the like are solved, and reversibility and identifiability of reinforced ancient buildings and historical buildings are improved.

Description

technical field [0001] The invention relates to the technical field of building reinforcement, in particular to an assembled obliquely stiffened thin-wall steel plate shear wall reinforcement structure suitable for old reinforced concrete buildings and a construction method thereof. Background technique [0002] With the passage of time, the reinforced concrete (RC) frame houses built in the last century, as industrial cultural heritage, carry the glory and dreams of China's efforts to catch up with the world for a hundred years, and have important social value. How to protect these historical relics for a long time is the key to restoration An important research topic for reinforcement. The protection of historical buildings should adhere to the principle of "preservation at the original site, key protection, and differential treatment". Compared with a specific building, due to its particularity, its common reinforcement scheme needs to be designed and adjusted according ...
