Angle steel reinforcing structure outside reinforced concrete beam and method thereof

Abstract

The invention provides an angle steel reinforcing structure outside a reinforced concrete beam and a method thereof. The angle steel reinforcing structure outside the reinforced concrete beam comprises lower reinforcing angle steel (1), upper reinforcing angle steel (2) and a U-shaped hoop (3), the lower reinforcing angle steel (1) can be matched and attached to a lower external corner of the reinforced concrete beam (21), the upper reinforcing angle steel (2) can be matched and attached to an upper internal corner of the reinforced concrete beam (21), the lower reinforcing angle steel (1) and the upper reinforcing angle steel (2) can be located between the U-shaped hoop (3) and the reinforced concrete beam (21), and the U-shaped hoop (3) can be fixedly connected with the reinforced concrete beam (21). According to the angle steel reinforcing structure outside the reinforced concrete beam and the method thereof, welding, floor penetrating and wet operation can be avoided, construction in a narrow space is facilitated, and the bearing capacity of the beam can be greatly improved.

Description

technical field [0001] The invention relates to the field of building structure reinforcement, in particular to an angle steel reinforcement structure outside a reinforced concrete beam, and a method for reinforcing an angle steel outside a reinforced concrete beam. Background technique [0002] Reinforced concrete beams are often used in frame structures as the main force-bearing members to bear the static and live loads transmitted from the floor, so it is very important to ensure the bearing capacity of the beams. Since changing the structural use or increasing the load requires increasing the bearing capacity of the original beams, it is necessary to reinforce the structural beams. Beam reinforcement methods include enlarging section method, pasting fiber composite material method, pasting steel plate reinforcement method, etc. However, the above methods have limitations when there is no wet operation, no welding, no influence on the waterproof layer or floor decoration...
