[0002] Precast beams are prefabricated in factories and then transported to the construction site for installation and fixation in the position required by the design. Concrete pouring: pour concrete evenly in the mold, and vibrate it with a vibrator to remove bubbles and impurities inside the concrete. According to the structural requirements of precast beams, steel bars are added when pouring concrete to enhance the bearing capacity and earthquake resistance of precast beams.

Before production, the required precast beam reinforcement frame is lifted by a hoisting device and moved to the top of the production mold body 1, and at the same time, it is lowered until it drops to a suitable depth inside the production mold body 1. At this time, the precast beam reinforcement support mechanism 2 is used to support it. During production, concrete is evenly poured inside the production mold body 1, and a vibrator is used to vibrate to remove bubbles and impurities inside the concrete.

[0029] Among them, any one of the several groups of equally spaced precast beam steel bar support mechanisms 2 includes a first U-shaped support 21 and a second U-shaped support 22 that are symmetrically distributed.
