Pressurizing and fixing device and reinforcing method for adhered steel plate of reinforced concrete beam
The invention discloses a pressurizing and fixing device and a reinforcing method for an adhered steel plate of a reinforced concrete beam. The pressurizing and fixing device comprises the reinforced steel plate and a pressurizing assembly. The reinforced steel plate is adhered on the surface of a to-be-reinforced beam, can be fixed at an earlier stage by the aid of the pressurizing assembly and is adhered on the surface of the to-be-reinforced beam by a structural adhesive layer; the pressurizing assembly comprises a bottom fixing steel member and beam rib fixing reinforcing steel bars, the beam rib fixing reinforcing steel bars are positioned on two wings, one end of each beam rib fixing reinforcing steel bar is connected with the bottom fixing steel member by a fastener, and the other end of each beam rib fixing reinforcing steel bar is fixed to the surface of the to-be-reinforced beam. The reinforcing method includes preliminarily anchoring the two beam rib fixing reinforcing steel bars in the middles of two sides of the to-be-reinforced beam; brushing the structural adhesive layer on the bottom surface of the beam, and adhering the high-strength reinforced steel plate on the bottom surface of the to-be-reinforced beam; connecting the bottom fixing steel member with the two beam rib fixing reinforcing steel bars by fixing bolts, and jacking the reinforced steel plates by the aid of the bottom fixing steel member and the beam rib fixing reinforcing steel bars; relaxing the reinforced steel plate after the requirement on the designed strength is met, disassembling the pressurizing assembly and completing a reinforcing procedure. The pressurizing and fixing device and the reinforcing method have the advantages of simple structure, low cost, good reinforcing effects, convenience in mounting and construction and the like.
