Bending reinforced concrete simply supported beam

Abstract

The invention relates to the technical field of buildings, in particular to a flexural reinforced concrete simply supported beam which comprises a base, a rotating disc is rotatably connected to the center of the upper end of the base, a first gear is fixedly connected to the lower end of the rotating disc, and second gears are rotatably connected to the positions, close to the four corners, of the interior of the base. A cylinder is fixedly connected to the interior of the second gear, extrusion blocks are rotatably connected to the left side and the right side of the lower end of the cylinder, the outer side of the first gear is in meshed connection with the outer side of the second gear, barbs are fixedly connected to the opposite sides of the extrusion blocks, and a moving rod is slidably connected to the position, close to the left side, of the interior of the rotating disc; the steel bar strut beam can be rapidly fixed, the requirement for manpower is reduced, compared with a steel wire and the like, the steel bar strut beam is more stable, meanwhile, in the upward pulling process, a certain tensile force is exerted on the steel bar, so that a certain prestress can be exerted on the steel bar, and concrete plays a more effective reinforcing role.

[0003] Before pouring concrete, it is necessary to build simply supported beams with steel bars, which can make the entire concrete firm when it solidifies and improve the strength of the concrete. However, when building multiple steel bars, the process is very cumbersome and requires multiple Each steel bar is fixed one by one, which brings a lot of labor to people, and does not necessarily achieve a qualified fixing effect at the same time.
