Claims

1. A positioning mechanism for pre-embedded channel steel in the cast-in-place concrete base wall of a precast cabin, comprising a left formwork (1) and a right formwork (2) of the cast-in-place concrete base wall, wherein tied wall reinforcement (3) is provided between the left formwork (1) and the right formwork (2), and a pre-embedded channel steel (4) is provided at the top of the wall reinforcement (3), characterized in that, A horizontal support nut (5) with a vertical lifting screw is installed directly above the pre-embedded channel steel (4). A left horizontal support rod (7) is fixedly connected to the left outer side of the horizontal support nut (5), and a right horizontal support rod (8) is fixedly connected to the right outer side of the horizontal support nut (5). The left end of the left horizontal support rod (7) is set on the top surface of the left template (1), and the right end of the right horizontal support rod (8) is set on the top surface of the right template (2). A vertical lifting screw (9) is screwed into the horizontal support nut (5), and a rotating handwheel (6) is set at the top of the vertical lifting screw (9). The bottom end is movably connected to a lifting connecting block (10); a left horizontal cantilever screw (14) is connected to the left end of the lifting connecting block (10), and a left L-shaped boom (16) is movably suspended on the left horizontal cantilever screw (14). The hook at the bottom end of the left L-shaped boom (16) is connected to the bottom end of the left vertical plate of the pre-embedded channel steel (4); a right horizontal cantilever screw (15) is connected to the right end of the lifting connecting block (10), and a right L-shaped boom (17) is movably suspended on the right horizontal cantilever screw (15). The hook at the bottom end of the right L-shaped boom (17) is connected to the bottom end of the right vertical plate of the pre-embedded channel steel (4).

2. The precast cabin precast concrete base wall embedded channel steel positioning mechanism according to claim 1, characterized in that, A ball (13) is provided at the bottom end of the vertical lifting screw (9). The ball (13) is movably fitted in the spherical cavity (12) inside the lifting connecting block (10). A top through hole (11) communicating with the spherical cavity (12) is provided on the top surface of the lifting connecting block (10). After the vertical lifting screw (9) passes through the top through hole (11), it is connected to the ball (13), thereby realizing the movable connection between the vertical lifting screw (9) and the lifting connecting block (10).

3. The precast cabin pre-embedded channel steel positioning mechanism in a cast-in-place concrete base wall according to claim 1 or 2, characterized in that, A first locking nut (18) is connected to the left horizontal cantilever screw (14) on the left side of the left L-shaped boom (16), and a second locking nut (19) is connected to the left horizontal cantilever screw (14) on the right side of the left L-shaped boom (16); a third locking nut (20) is screwed onto the right horizontal cantilever screw (15) on the left side of the right L-shaped boom (17), and a fourth locking nut (21) is screwed onto the right horizontal cantilever screw (15) on the right side of the right L-shaped boom (17).
