Why is the tower crane attached to the wall hinged?

The tower crane attached to the wall is hinged, because the tower crane is attached to resist wind pressure and torque, so the hinged way can play a buffering role. The use of hinges is correct and cannot transmit torque. If it is a rigid connection, under the action of wind load, this force will be transferred to the main structure through the buttress rod, which will easily cause the connection between the embedded parts and the main structure to be destroyed.

Matters needing attention in making attached wall of tower crane

When hoisting the tower top at the construction site, it is necessary to connect the buttress reinforcement. We can see that each construction site is connected in a different way. Some are only connected with the tower crane hoop and the embedded parts of the wall, and hinged with the tower crane hoop and the embedded parts of the wall.

Traditional tower cranes are often attached directly to the main structure, and then added to climb. However, with the development of the construction industry, the modeling design of the main structure is becoming more and more complicated, which leads to the limitation of the layout of tower cranes in the construction site, making it difficult to arrange the position of tower cranes attached to the wall of the main structure.

When the double-deck platform meets the tower crane attached to the wall in the process of ascending or descending, the flap is turned up along the hinge to a vertical position to form a fence, and the telescopic support device is recycled inward to form a gap, so that the double-deck platform is attached to the wall through the tower crane.
