Abstract
The invention provides a service-period cracking beam reinforced by steel plate anchoring fiber cloth and a reinforcing method of the service-period cracking beam. The cracking beam comprises a beam body, wherein the beam body comprises a front side surface, a bottom surface and a rear side surface which are sequentially connected; the longitudinal carbon fiber cloth is adhered to the bottom surface; the longitudinal carbon fiber cloth extends to the front side surface and the rear side surface; the longitudinal carbon fiber cloth is arranged at intervals and away from the center line of the beam body; the transverse carbon fiber cloth is adhered to the front side surface and the rear side surface and adhered to the surface of the longitudinal carbon fiber cloth; the transverse carbon fiber cloth is arranged in the length direction of the beam body; one section, which is away from the center line, of basalt fiber cloth is adhered to the longitudinal carbon fiber cloth close to the basalt fiber cloth; the basalt fiber cloth is adhered to the lower surface, which is back to the bottom surface of the beam body, of the longitudinal carbon fiber cloth; steel plates are arranged at intervals along the width direction of the beam body; the steel plate is fixed on the bottom surface; and the steel plate is attached to the lower surface of the basalt fiber cloth. By improving the beam reinforcing mode, the bearing capacity of the beam is improved, and meanwhile, effective control over crack development is achieved.
Description
technical field [0001] The invention belongs to the technical field of bridge reinforcement, and in particular relates to a service cracked beam reinforced by steel plate anchor fiber cloth and a reinforcement method thereof. Background technique [0002] Because the reinforced concrete beam structure has the advantages of good fire resistance, good durability, high integrity, convenient prefabrication, economical materials, easy factory and standardized construction, it is widely used in industrial buildings, civil buildings, water conservancy facilities and small bridges. [0003] However, during the long-term use of the reinforced concrete beam structure, due to the dual effects of the natural environment and the use environment, the reinforced concrete beam structure will deteriorate, and cracks will appear on the surface of the reinforced concrete beam structure, which will lead to a decrease in the bearing capacity. structural failures etc. Contents of the invention ...
