Problems solved by technology

However, the integrity of the prefabricated cross-shaped tower crane foundation is poor, and the foundation pressure is not easy to control, resulting in foundation damage; at the same time, this foundation has an obvious weak axis, which greatly weakens its ability to resist overturning. Such problems have also occurred in recent years
In addition, it is troublesome to assemble and construct through prestressed tensioning, and the technical requirements for on-site tensioning are also high, and prestressed steel bars cannot be reused, resulting in waste

Embodiment Construction

[0024] As shown in the figure: a bolt-connected box-shaped prefabricated concrete tower crane foundation, the tower crane foundation includes a plurality of box-shaped components composed of three structural forms, the middle position of the foundation has a central box-shaped component 1, and the center box A box-shaped member 2 is arranged on the front, rear, left, and right sides of the shaped member 1, and a box-shaped member 3 is arranged on one side of the box-shaped member 2. There are bolt holes 5 on the side walls of each box-shaped member, and each box-shaped member passes through its side wall. Insert the bolt welding body 8 into the bolt hole 5 for connection after the groove 6-1 and the protrusion 6-2 fit together.

[0025] The central box-shaped member 1 is a hollow box-shaped structure, the concrete plate on the top of the box has bolt holes 4, and each surface around the central box-shaped member 1 has grooves 6-1 respectively.

[0026] The box-shaped member 2 ...

Abstract

The invention relates to a precast concrete tower crane foundation, in particular to a prefabricated precast concrete tower crane foundation in the shape of a bolt connecting box, belonging to the technical field of the constructional machinery. The prefabricated precast concrete tower crane foundation in the shape of a bolt connecting box comprises a plurality of box-shaped components in three structural forms. The box-shaped components are connected into a whole body by bolts. Solid or liquid is filled in the box-shaped components so as to be used weight balancing material. The prefabricated precast concrete tower crane foundation can be installed conveniently and constructed easily on the site and has low manufacturing cost. The weight balancing material can be filled and removed conveniently. The prefabricated precast concrete tower crane foundation can meet the requirement of the tower cranes of various types and models, has similar stability in all directions, has no weak axis and has good overturning resisting ability. The bolts for connecting the box-shaped components can be used repeatedly.

Description

technical field [0001] The invention relates to a concrete tower crane foundation, in particular to a bolt-connected box-shaped prefabricated concrete tower crane foundation, which is suitable for tower cranes of various types and models, and belongs to the technical field of construction machinery equipment. Background technique [0002] Tower crane is an important equipment for construction hoisting and transportation operations in the construction industry. Most of the vertical transportation of building materials is completed by tower cranes. In order to ensure the normal operation of the tower crane, the tower crane must be installed on the tower crane foundation. The tower crane foundation must have sufficient anti-overturning ability and ensure that the foundation is not damaged; at the same time, the tower crane foundation should be easy to manufacture, transport and load. There are various forms of tower crane foundations. Currently, the most widely used tower crane...
