Concrete structural beam shear-resistant reinforcing method and concrete structural beam shear-resistant reinforcing structure
The invention provides a shear-resistant reinforcing method for a concrete structural beam. The shear-resistant reinforcing method comprises the specific steps that a first steel plate is laid on a concrete floor; mounting holes allowing the U-shaped steel plate hoops to penetrate through are formed in the target position of the concrete floor, and the target position is the position within the target range of the side face of the newly-added steel beam; the concrete structural beam and the anchor plate are wrapped with a U-shaped steel plate hoop, the U-shaped steel plate hoop penetrates through the mounting hole to abut against the first steel plate, and the U-shaped steel plate hoop is arranged in a manner of avoiding the rear anchoring anchor bolt; the U-shaped steel plate hoop is welded to the first steel plate to form a closed steel plate hoop; the space between the U-shaped steel plate hoop and the concrete structural beam and the space between the U-shaped steel plate hoop and the anchor plate are filled with structural adhesives, so that the U-shaped steel plate hoop and the concrete structural beam are bonded, the U-shaped steel plate hoop and the anchor plate are bonded, and the U-shaped steel plate hoop, the first steel plate, the concrete structural beam and the concrete floor slab are combined into a whole; therefore, the shear bearing capacity of the original concrete structural beam is effectively improved.
本发明提供了一种混凝土结构梁抗剪加固方法，具体步骤包括：在混凝土楼板上铺设第一钢板；在混凝土楼板的目标位置开设用于U型钢板箍穿设的安装孔，其中，目标位置为新增钢梁侧面目标范围之内的位置；将U型钢板箍包裹混凝土结构梁及锚板，并穿过安装孔，以与第一钢板抵接，其中，所述U型钢板箍避让所述后锚固锚栓设置；将U型钢板箍焊接于第一钢板，以形成封闭钢板箍；在U型钢板箍与混凝土结构梁之间，以及U型钢板箍与锚板之间填充结构胶，以使U型钢板箍与混凝土结构梁之间，以及U型钢板箍与锚板之间粘接，以使U型钢板箍及第一钢板与混凝土结构梁和混凝土楼板结合为一体，从而有效地提高了原混凝土结构梁的抗剪承载力。
