A connection lock for prefabricated components includes an auxiliary part and a main part which are each provided with a fixing structure for connecting with a prefabricated component in an anchoring fit manner. The auxiliary part includes an auxiliary part body, an auxiliary part transmission structure, and a lock pin structure which is movably mounted to the auxiliary part body. The auxiliary part transmission structure is in transmission fit with the lock pin structure. The main part includes a main part body, a main part transmission structure, and a locking structure. An inserting channel fitted with the lock pin structure is formed in the main part body. The locking structure is adjustably mounted in the main part body. The main part transmission structure is in transmission fit with the locking structure. It is rapid and convenient to operate, and the construction efficiency is higher than traditional construction methods.

Mechanical lock for building component connection

An assembled subway station and a construction method thereof are provided. The assembled subway station includes a plurality of components combined in a ring shape, comprising a bottom plate component, two bottom corner components, two side wall components, a middle plate component, two top corner components, and a top plate component. Connection surfaces of each component are each provided with a concave-convex structure being matched with another concave-convex structure on a relevant connection surface of an adjacent component. Butt joint positions of two adjacent components are filled with sealing structures. The embedded grooves of two adjacent components are oppositely arranged, and connecting members for exerting opposite fastening forces on the two adjacent components are installed in the oppositely arranged embedded grooves. The opposite fastening forces are exerted on the two adjacent components through connecting members to ensure sealing structures at the butt joint position and achieve better sealing effects.

Assembled subway station and construction method thereof

A connection assembly for prefabricated components provided herein includes two C-shaped groove members and an H-shaped connection member. The C-shaped groove members are each provided with a component connecting part for fixedly connecting with a component, the H-shaped connection member includes a middle web and two side flanges, notches of the C-shaped groove members are in clearance fit with the web, and the side flanges are in stop fit with inverted edges of the C-shaped groove members when the H-shaped connection member is inserted between the C-shaped groove members. The C-shaped groove members and/or the H-shaped connection member are each provided with wedge members, and the wedge members have wedge surfaces for guiding the two C-shaped groove members to be fastened oppositely.
