Problems solved by technology
The movable jib tower crane with an independent foundation has a heavy weight and high anti-overturning ability, and the design and calculation of the tower crane piles and caps are required, which is more complicated than the design and calculation of the conventional small tower crane with flat arms
The construction cost of the tower crane pile is high, the amount of concrete used for the cap is large, the foundation construction is complicated, and the input cost of materials and labor is high

The invention relates to a movable arm tower crane fixed type foundation construction method and a movable arm type tower crane structure. The method comprises the steps that the model of a movable arm tower crane is selected; the position of the movable arm tower crane is determined, and a BIM technology is used for simulating and checking the positioning rationality; an existing engineering pileis selected, and the bearing platform range is determined; a bearing platform beam is designed according to the selected engineering pile; a calculation foundation model of an engineering pile and bearing platform beam combined structure is established; whether the structural safety of the basic model meets a structural safety preset condition or not is judged; if the structural safety of the basic model meets the structural safety preset condition, construction is carried out; a movable arm tower crane foundation section is pre-buried; bearing platform beam steel bars are installed; bearingplatform beam concrete is poured and cured; and if the structural safety of the foundation model does not meet the structural safety preset condition, the selection of the existing engineering pile isre-executed and the bearing platform range is determined. According to the movable arm tower crane fixed type foundation construction method, the tower crane foundation construction work amount is reduced, the material consumption is reduced, the labor cost is saved, and the whole tower crane structure is high in safety.
Description
technical field [0001] The invention relates to the technical field of building tower crane foundation construction, and more specifically refers to a construction method for a fixed foundation of a boom tower crane and a structure of a boom tower crane. Background technique [0002] In recent years, with the development of the economy and the progress of urbanization, the height and number of high-rise buildings in my country have increased rapidly, forming a boom in skyscraper construction. Wire. The foundation of super high-rise buildings is usually in the form of piled raft foundation, and the main structure has a high steel content. It needs to be hoisted by a large boom tower crane to ensure the lifting and installation of components. The economy, safety and applicability of large boom tower cranes are particularly important. [0003] In the case of super high-rise construction, the jib tower crane can be installed before or after the construction of the raft foundati...
