Embodiment 1

[0029] Example 1: Such as Figures 1 to 4 As shown, a steel platform tower crane foundation includes bored piles, steel lattice columns and steel caps;

[0030] The number of the bored cast-in-situ piles is four, and the connecting line of the pile positions is square, the pile diameter is 0.8m, the distance between adjacent piles is 2.4m, and the effective pile length is 26m.

[0031] The steel lattice columns are welded by four L140×140×14mm angle steels and 440×200×12mm slabs. The cross section is 480mm×480mm square, 11.9m long, and the center distance of slabs is 500mm.

[0032] The top of the steel lattice column is fixed with a steel backing plate, the steel backing plate is Q235 grade steel, the specific size is 760mm×760mm×20mm, the axis of the steel backing plate overlaps with the axis of the steel lattice column, and its The parts protruding from the steel lattice columns around are provided with screw holes for connecting with the lower steel beams; the top four ...

Abstract

The invention discloses a steel platform tower crane foundation and a construction method thereof. The steel platform tower crane foundation comprises bored piles, steel latticework columns and a steel bearing platform. The steel latticework columns are fixed on the bored piles, and the steel bearing platform comprises four steel beams, wherein two of the four steel beams are lower steel beams, and the other two steel beams are upper steel beams. The upper steel beams are fixed on the lower steel beams to form a #-shaped structure, the lower steel beams are fixed on the steel latticework columns, and a tower crane is fixed on the upper steel beams. The steel platform tower crane foundation has the advantages that the tower crane foundation steel beams are machined in a factory, preformed bolt holes are drilled in a lofting mode according to the sizes of tower crane standard section bolts, and accuracy of the bolt holes is high; on-site assembling and disassembling are convenient, the tower crane can be installed as long as the foundation is installed, and maintenance time of concrete is eliminated; in the foundation disassembling process, only the bots need to be detached for hoisting, concrete does not need to be crushed, and disassembling is convenient; disassembled steel beams can be repeatedly used, and construction cost is saved.

Description

technical field [0001] The invention relates to a tower crane foundation, in particular to a steel platform tower crane foundation and a construction method thereof, belonging to the technical field of building construction. Background technique [0002] For large-scale foundation pits, the tower crane needs to be placed in the foundation pit to meet the needs of vertical transportation, and the foundation pit area is relatively large. The foundation pit enclosure is designed with reinforced concrete internal support. The tower crane needs to be installed before the earthwork excavation. After the earthwork excavation, the tower crane Installation and hoisting are difficult, and tower cranes are also required for reinforced concrete support construction. [0003] Generally, the tower crane foundation adopts pile-bearing lattice column concrete foundation. The foundation construction is relatively conventional steel bar, formwork, and concrete technology, and the constructio...
