Description
Technical Field
[0001] The utility model relates to the technical field of tower crane foundation assembly, and specifically relates to a tower crane foundation assembly structure. Background Art
[0002] A tower crane, also known as a tower hoist, is an important construction machinery, widely used in various construction projects, especially playing a crucial role in high-rise building construction. With its unique structure and high lifting height, the tower crane provides great convenience for construction. There are various types of tower cranes, which can be classified into multiple types according to different classification methods. For example, according to the slewing mode of the tower body structure, it can be divided into top-slewing and bottom-slewing tower cranes, and according to the luffing mode, it can be divided into luffing jib and trolley jib tower cranes, etc. And the assembly of the tower crane foundation is an important construction task, involving steps such as foundation preparation, installation of tower crane components, connection and commissioning. To ensure construction safety and quality, the construction process needs to be carefully planned and organized. Before construction, the tower crane foundation needs to be strictly inspected to ensure that the concrete strength meets the design requirements, and the flatness and levelness of the foundation are also inspected. In addition, necessary construction tools and materials need to be prepared, such as a truck crane, wrenches, adjustable wrenches, socket wrenches, slings, hemp ropes, etc. During construction, safety operation procedures should be strictly followed, and safety protection equipment such as safety helmets and safety belts should be worn. At the same time, obvious safety warning signs should be set up at the construction site to remind people to pay attention to safety. For high-altitude operations, anti-falling measures should be taken, such as erecting scaffolding and using safety belts.
[0003] In the assembly of the tower crane foundation, when the base of the tower crane is connected to the reserved threaded rod through a nut, the overall connection is prone to leakage in rainy days, resulting in damage to the internal connection state and posing a risk of collapse of the whole.
