Description

Universal assembly type equipment foundation

Technical Field

The invention relates to the technical field of tower cranes, in particular to a universal assembly type equipment foundation.

Background

The tower crane is the most common hoisting equipment on the construction site, is also called as a tower crane, is lengthened section by section (called as a standard section for short), is used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like for construction, and is indispensable equipment on the construction site.

The tower crane foundation is the foundation of the tower crane and is a necessary condition for keeping the safe operation of the tower crane. Because the weight is hung by the hanging arm which is hung out, the tower crane has very large dumping moment, so the tower crane foundation needs to meet the requirements of the tower crane on overturning stability, foundation bearing capacity and base crack resistance. During the actual application, be connected through pre-buried bolt and four ring flanges of tower crane bottom on the tower crane basis, realize the fixed of tower crane, four ring flanges of tower crane bottom distribute on same circle usually.

The traditional tower crane foundation is mostly cast-in-place concrete, and after construction, large amount of waste of reinforced concrete can not be effectively converted ecologically, so that heavy load is caused to the environment. And in each construction of the cast-in-place concrete foundation, a large amount of steel bars and concrete need to be added into each tower crane, so that the tower crane cannot be recycled, and the resource waste is caused. In addition, the long time for concrete preparation and maintenance is a big adverse factor that hinders the progress of the construction period.

Therefore, at present, the assembly type tower crane foundation is adopted, prefabricated concrete base blocks are transported to the site to be assembled, the mode is convenient to install, the tower crane foundation can be detached and taken away after construction is finished, and the load of the environment is relieved. However, the radius of the circle surrounded by the four flange plates at the bottoms of the tower cranes of different models is different, namely the center distance of the flange plates is different, the conversion performance of the conversion of the existing tower crane foundation between tower cranes of different models is weak, the existing tower crane foundation cannot be suitable for the installation of different tower cranes, the tower crane foundation cannot be reused after being disassembled, and the cost is still very high.

Disclosure of Invention

The invention aims to provide a universal assembly type equipment foundation so as to solve the problem that the existing tower crane foundation cannot be suitable for installation of tower cranes of different models.

In order to achieve the purpose, the invention provides the following technical scheme:
