Embodiment Construction
[0022] see Figure 1 to Figure 5 , in the embodiment of a pre-tensioned prestressed reinforced concrete prefabricated beam given in the present invention, the beam body is an inverted T-shaped structure composed of a horizontal rectangular compression part 1 and a vertical rectangular shear part 2, and the vertical The rectangular shear part 2 is provided with a stirrup 21, and the part of the stirrup 21 protrudes from the upper surface of the shear part 2, and the horizontal rectangular compression part is also provided with a stirrup 12, and the steel strand 4 is longitudinally Embedded in the concrete of the compression part 1 . The beam body in the present invention is designed as a structure composed of the compression part 1 and the shear part 2. This structure can well solve the problem that the concrete compression resistance and the shear resistance do not match in the existing beam body, so that the beam body The structure is more reasonable and the mechanical perfo...
