Description

Technical Field

[0001] The utility model relates to the technical field of assembled subway station construction, in particular to a bolt construction device for side walls and top plates of assembled subway stations. Background Art

[0002] In order to reduce the construction cost of prefabricated stations, most of the fertilizer troughs of prefabricated stations under construction are narrow fertilizer troughs with a designed width of 30 cm. In such a narrow space, it is often difficult to connect the side walls and the top plate with bolts when assembling the components of the prefabricated station. In some places, the fertilizer troughs are too narrow, and personnel cannot climb to the bottom of the side wall connector to install the gasket nut, resulting in the inability to apply torque to the connection between the side wall and the top plate, and the design requirements cannot be met. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] The technical problem to be solved by the utility model is that when assembling prefabricated station components, it is often difficult to connect the side walls and the top plate with bolts. In some places, due to the narrowness of the fat trough, personnel cannot climb to the bottom of the side wall connector to install the gasket nut, resulting in the inability to apply the torque connecting the side wall and the top plate, and the design requirements cannot be met.

[0008] The lower part of the fine-rolled threaded steel is threadedly connected to a lower steel pad, and a fixing bolt connected to the fine-rolled threaded steel is provided on the lower side of the lower steel pad. A hemp rope is wound around the upper rod of the fine-rolled threaded steel, and the top of the hemp rope is connected to the lifting device.

[0009] An upper steel plate is threadedly connected to the top of the fine-rolled threaded steel bar, and two fixing bolts threadedly connected to the fine-rolled threaded steel bar are arranged on the upper side of the upper steel plate. A wire rope locker is arranged on the outer side of the hemp rope, and the wire rope locker locks the hemp rope to the fine-rolled threaded steel bar.

[0010] As an improvement, the wire rope locker is provided with a pair of upper and lower distributed ones.

[0011] As an improvement, the locking end of the wire rope locker matches the thread groove of the precision-rolled threaded steel bar.

[0012] As an improvement, the wire rope locker includes a locking plate and a fixing steel wire. Two fixing grooves are reserved in the locking plate. Both ends of the fixing steel wire pass through the fixing grooves and are fixed to the locking plate.

[0013] As an improvement, an arc-shaped docking plate is provided on the inner side of the fixing wire fixing ring.

[0014] (III) Beneficial effects
