Four-beam steel structure tower crane foundation provided with counterweights and capable of being folded and moving quickly

Abstract

The invention relates to the field of building construction machines, in particular to a four-beam steel structure tower crane foundation provided with counterweights and capable of being folded and moving quickly. The four-beam steel structure tower crane foundation mainly comprises main beams (1), a cross-shaped supporting frame (4), the main counterweights (2), the main beam counterweights (3)and ground anchors (1101) and is characterized in that the four steel structure main beams (1) and the adjacent main beams are matched through lug plates (15) with holes and hinged through pin shafts(16), wherein the lug plates (15) with the holes are arranged on the two sides of the front ends of the four steel structure main beams (1); the four steel structure main beams are distributed in a cross shape; the cross-shaped supporting frame (4) is arranged among the four main beams and connected with front blocks (14) of the four main beams through bolts (7) correspondingly, and a set of correction sizing blocks (5) is arranged between the cross-shaped supporting frame (4) and the front block (14) of each of the four main beams; and each main counterweight (2) is arranged between the two corresponding adjacent main beams and pressed on rib plates (17 and 18) at the bottoms of the main beams, and the main beam counterweights (3) are arranged in a main beam box body structure. The four-beam steel structure tower crane foundation is stable in structure, simple in manufacturing process, convenient and fast to move and transport and high in repetition utilization rate, compared with anexisting tower crane foundation, resource waste is reduced, the cost is saved, and the environment is protected.

Description

Technical field: [0001] The invention relates to a tower crane foundation, in particular to a tower crane foundation with a four-beam steel structure and a counterweight that can be quickly folded and moved, and belongs to the field of construction engineering hoisting machinery. Background technique: [0002] Tower cranes are important mechanical equipment in construction projects. They are often used in the construction of large and medium-sized projects such as high-rise or multi-storey buildings, factory buildings, large warehouses, industrial towers, and bridges. The use of tower cranes is inseparable from the tower crane foundation. The tower crane foundation is an important guarantee for the normal operation of the tower crane. The traditional tower crane foundation is made of reinforced concrete weighing dozens of tons. When the project is completed or partially completed, the tower crane needs to be dismantled or moved. location, and the tower crane foundation made ...

AI Technical Summary

Problems solved by technology

The new composite tower foundation changes the traditional reinforced concrete monolithic pouring into multiple reinforced concrete prefabricated parts assembled on site, connected and fixed together by steel strands. After the project is completed, the tower crane foundation is disassembled and transported to the next place of use. The type of tower base has improved the reuse rate and reduced waste, but some shortcomings have gradually emerged in the process of promotion and use

[0003] First, these concrete prefabricated parts contain many reserved holes and embedded parts with different and complicated shapes, which are difficult to manufacture and require special molds;

[0004] Second, even if the original integral pouring of the new composite tower base is changed to a multi-part assembly, each part still has a relatively large weight. It is easy to cause bump damage and affect the use;

[0005] Third, on-site assembly requires multiple people to cooperate with the crane, which is not convenient and quick enough;

[0006] Fourth, the connection between the prefabricated parts of the new concrete composite tower foundation is usually steel strands. The tower crane foundation must balance the shear force and torsion force from the tower crane. The steel strands bear a large load, and the confinement devices at both ends are loose. risks of
