Description

Technical Field

[0001] The invention relates to a tower crane foundation embedded part position regulating device. Background Art

[0002] Tower cranes are large-scale construction equipment widely used in civil construction. A good foundation is a crucial factor in their safe operation. Tower crane verticality is a crucial operational monitoring parameter, and the maximum height difference of embedded foundation components is a key factor affecting verticality.

[0003] Tower crane foundation embedded parts are placed and adjusted after the tower crane's cap reinforcement is tied. Typically, the embedded parts are placed on a dedicated saddle, which in turn rests on the underlying reinforcement. For larger tower cranes, the mass of the embedded parts, or due to construction issues like vibration, can cause excessive pressure on the cap formwork directly below the embedded parts before the concrete solidifies, leading to minor deformation and settlement. Once settlement exceeds the specified limit, since the cap concrete has already solidified, verticality adjustment is often performed using standard correction sections, which wastes significant manpower, material, and financial resources and increases safety risks for the tower crane.

[0004] The current problems with this process are:

[0005] 1. The bearing capacity of the bottom of the pedestal is limited, and it is difficult to ensure that it will not deform;

[0006] 2. It is difficult to ensure that the embedded parts are not affected while fully vibrating the concrete of the tower crane foundation;

[0007] 3. Using embedded parts supports such as horse stools cannot quickly and accurately adjust the position of embedded parts. Therefore, for the lattice column tower crane base system, it is necessary to find a component with high rigidity as the load-bearing body and a device that can quickly and accurately adjust the embedded parts.
