Concrete beam section increasing reinforcing structure and construction method thereof
The invention discloses a reinforcing structure for increasing the section of a concrete beam and a construction method thereof. The reinforcing structure comprises a plurality of embedded steel bar connecting pieces, a plurality of transverse perforated steel plates, a plurality of longitudinal steel bars and self-compacting concrete. A plurality of embedded steel bar connecting pieces which are arranged in an array mode are embedded in a bottom plate of a concrete beam, a plurality of transverse perforated steel plates which are arranged on the bottom plate of the concrete beam in parallel in the direction parallel to the cross section of the concrete beam are welded to the embedded steel bar connecting pieces, and the bottom plate of the concrete beam is divided into a plurality of pouring areas through the transverse perforated steel plates; a plurality of longitudinal steel bars sequentially penetrate through a plurality of round holes, located in the same longitudinal direction, in a plurality of transverse perforated steel plates, the plurality of longitudinal steel bars and the plurality of transverse perforated steel plates jointly form a steel framework, self-compacting concrete is sequentially poured on the outer side of a concrete beam bottom plate along a plurality of pouring areas, and the steel framework and the concrete beam form a whole. According to the method, the concrete pouring construction quality of the section-increasing reinforcing method is improved, and the application effect of reinforcing the concrete beam by adopting the section-increasing reinforcing method is improved.
