A movable modular assembled tower crane steel bearing platform and its installation method

Abstract

The invention discloses a movable modular assembled tower crane steel bearing platform and an installation method. The steel bearing platform is arranged around a building to be built, and no less than four bearing platform modules pass through connecting pieces and high-strength bolts during installation. combined. Each of the platform modules includes an upper cover plate and a lower supporting plate, and there are corner supports, side supports, inner supports and ring supports for supporting reinforcement between the upper cover plate and the lower supporting plate, and the lower part of the lower supporting plate There is a fixing ring for positioning and fixing. The steel pipe pile passes through the fixing ring and is connected with the annular support in the cap module. The sliding parts are connected to the side supports in the cap module through the spiral braces, and the tower crane foundation section feet are respectively installed and fixed in the sliding parts in the middle of the four cap modules. The invention can freely adjust the number of cap modules according to engineering needs; the on-site installation is quick, and the construction efficiency is high; after installation, the structural rigidity is large and the safety is good; the position of the components can be adjusted according to the size of the actual tower crane foundation section, and the adaptability is strong.

Description

technical field [0001] The invention relates to the technical field of steel caps for tower cranes in civil engineering, in particular to a movable and modular assembled steel caps for tower cranes and an installation method. Background technique [0002] With the continuous acceleration of urban construction in our country, the tower crane that meets the high-altitude transportation function on the construction site has become an indispensable main construction machine in the modern construction industry. Especially driven by prefabricated buildings, the number and quality of components required for construction have greatly increased. The application of tower cranes has played a vital role in speeding up construction progress and reducing project costs. [0003] As an important part of the tower crane, the tower crane cap plays the role of fixing the tower crane and bearing the upper load during use. The reliability of the tower crane cap directly affects the safety of the...

Problems solved by technology

This kind of cap has the following disadvantages: (1) The construction process of the cap is complicated, involving multiple processes such as steel bar binding, formwork support, concrete casting, etc., and the construction period is long; (2) The erection of the cap requires a large amount of steel bars And concrete, the investment cost is huge, and the ecological transformation cannot be carried out after demolition, and the pollution to the environment is relatively large; (3) For high-rise buildings, the height of the cap is close to the height of the basement, and if the two are cross-constructed, it will easily cause construction difficulties
