Connecting mechanism for connecting ALC light partition wall and PC component, and using method

The invention discloses a connecting mechanism for connecting an ALC light partition wall and a PC component and a using method, and belongs to the technical field of building construction. The connecting mechanism comprises an ALC light partition wall, a horizontal PC component, a floor slab and a vertical PC component, and the ALC light partition wall body and the vertical PC component are connected through connection rivets; the ALC light partition wall is connected with the horizontal PC component and the floor slab through pipe clamp units; cement mortar is filled between the ALC light partition wall and the horizontal PC component and between the floor slab and the vertical PC component. The connection rivets are screwed into mounting holes, meanwhile, cement mortar is pre-laid on the ALC light partition wall, the ALC light partition wall is fixed to the vertical PC component, the top end and the bottom end of the ALC light partition wall are fixed through shooting nails, therefore, the ALC light partit
