Tower crane foundation structure applicable to restricted space

Abstract

The invention discloses a tower crane foundation structure applicable to restricted space and relates to the technical field of bridge construction. The tower crane foundation structure applicable tothe restricted space comprises a cushion cap, a pier body arranged on the cushion cap, a steel pipe column and two I-steel beams; one end of the steel pipe column is inclined outwards and mounted ontothe cushion cap through a cushion cap embedded part, the other end of the steel pipe column is connected with the two I-steel beams, and one ends of the two I-steel beams are connected with pier bodyembedded parts to arrange the two I-steel beams onto the same horizontal plane. According to the tower crane foundation structure applicable to the restricted space, the steel pipe column is inclinedoutwards, the two I-steel beams are basically horizontally arranged above the cushion cap, the I-steel beams, the steel pipe column, the cushion cap and the pier body form an inverted trapezoid, so that the structural strength of the tower crane foundation structure applicable to restricted space can be increased; meanwhile, the two horizontal I-steel beams form a mounting surface of a tower crane, so that the weight of the tower crane is directly born by the cushion cap of the restricted space, the support legs of the tower crane can be arranged outside the cushion cap, and the constructiondifficulty of the tower crane foundation structure applicable to the restricted space can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a tower crane foundation structure used in a confined space. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, used to lift construction materials such as steel bars, corrugated wood, concrete, steel pipes and so on. In all kinds of bridge construction applications, the tower crane is usually installed on the foundation cap of the ground, and the embedded parts of the tower crane foundation are directly embedded during the construction of the cap, and fixed by the pre-embedded form of anchor screws, and many standard joints and attachment devices are added. . Due to the large size and heavy weight of the tower crane, it is necessary for the foundation cap to have enough space for the foundation setting of the tower crane. [0003] At present, tower crane foundations cannot be installed directly on pier caps ...

AI Technical Summary

Problems solved by technology

[0004] 1) Large-scale lifting equipment is required to insert and pull steel pipe piles in the water next to the cap, and the construction interference is large. A large number of steel pipe piles need to be inserted into the soil, and there are many construction materials. In addition, the steel pipe pile foundation usually has insufficient rigidity. characteristics;

[0005] 2) The tower crane foundation installed on the cofferdam is only applicable to the double-wall steel cofferdam, and the cofferdam must be fixedly connected to the cap. Long construction period;

[0006] 3) Expanding the foundation is only suitable for land bridges with good geological conditions. The foundation is composed of a large number of steel bars and concrete, and the amount of materials is large, which occupies the space outside the bridge, increases the construction land, and increases the construction cost
