Reinforcing structure of existing structural beam and construction method thereof
The invention discloses a reinforcing structure of an existing structural beam. The reinforcing structure of the existing structural beam comprises the structural beam. Two ends of the structural beam are respectively connected with a structure column, an outer wrapping steel sleeve is arranged on the structural beam, multiple reinforcing ribs are arranged between the bottom of the structural beam and the outer wrapping steel sleeve, and the end portions of the reinforcing ribs are embedded in the structure columns. Two sides of the outer wrapping steel sleeve are provided with grouting tunnels, and angle steels are symmetrically arranged on the two sides of the outer wrapping steel sleeve and the beam plate junction. The vertical portions of the angle steels are connected with the structural beam through anchor bolts, and the horizontal portions are provided with high-strength bolts which penetrate through the beam plate. A connecting hoop plate is arranged between the tops of every two high-strength bolts which are located on the same plane, and the position, corresponds to the structural beam, between each connecting plate and the beam plate is provided with a hogging moment steel plate. Due to the fact that the existing structural beam increases the section and is provided with the outer wrapping steel sleeve, the anti-bending and anti-shearing capability of the existing structural beam is greatly improved, the bearing capability for the integrated extra-large load of the applied local portion is satisfied, and the hidden danger after completion and the economic loss due to removing and reconstruction are effectively avoided.
