[0028] The utility model provides a prefabricated beam outer formwork, an outer formwork bottom plate 2 is arranged on a base 1, the two opposite sides of the outer formwork bottom plate 2 along the width direction are connecting sides, two outer formwork side plates 3 are arranged on the opposite sides of the outer formwork bottom plate 2 along the width direction, the two outer formwork side plates 3 correspond to the two connecting sides one by one, the lower ends of the outer formwork side plates 3 are connected to the connecting sides by screw connectors 6, and an installation gap is provided between the end faces of the lower ends of the outer formwork side plates 3 and the connecting sides; two sealing members 4 correspond to the two installation gaps one by one, the sealing members 4 are arranged in the installation gap, and the opposite sides are respectively abutted against the outer formwork bottom plate 2 and the outer formwork bottom plate 2, so that the outer formwork bottom plate 2 and the outer formwork side plates 3 are sealed and matched, and such an arrangement can seal the gap between the outer formwork side plates 3 and the outer formwork bottom plate 2 to avoid leakage of slurry.

[0029] Furthermore, the outer mold bottom plate 2 has two opposite ends in the width direction protruding downward to form a first connecting portion, the first connecting plate is penetrated with a first through hole, the bottom of the outer mold side plate 3 is protruding downward to form a second connecting portion, the second connecting portion is penetrated with a second through hole, the first connecting portion corresponds to the second connecting portion, the screw connection 6 passes through the first through hole and the second through hole to install the outer mold side plate 3 on the connecting side, and the installation gap is located above the first connecting plate. With this arrangement, the seal 4 and the screw connection 6 do not interfere with each other, thereby improving the sealing effect of the seal 4.

[0030] Furthermore, since the outer form side plate 3 is tilted, when concrete is injected, the outer form side plate 3 will be subjected to an outward force, thereby increasing the installation gap. In this embodiment, the precast beam outer form also includes two abutting components 5, which are arranged on opposite sides of the outer form bottom plate 2 along the width direction. Each abutting component 5 is arranged on the base 1 and abuts against the outer form side plate 3 to abut the lower end of the outer form side plate 3 against the connection side.
