Embodiment Construction

[0038] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] Such as Figure 1-9 As shown, it is a schematic diagram of each component of the assembled tower foundation described in this embodiment. An assembled tower foundation is divided into a bottom foot plate in contact with the ground, an arch shell 14, and a cap ring beam 13 on the top, and an arch shell 14 It is arc-shaped, and the angle α between it and the bottom foot plate is 45-75°, and the thickness of the arch shell plate is 150-200mm; the bottom foot plate is ring-shaped, and the enti...

Abstract

The invention discloses a fabricated tower footing which consists of a bottom foot plate which contacted with the ground, an arch shell and a pile cap ring beam arranged at the top. The arch shell is arch-shaped and the angle Alpha between the arch shell and the bottom foot plate is 45-75 degrees; the thickness of the arch shell is 150-200mm; and the bottom foot plate is annular. The entire tower footing is divided into four identical parts along the axial section, and when the tower footing is used, the four parts are fabricated in the shape of the arch shell to form an integral body. The tower footing is added with a counterweight equilibrium and stabilizing column foot according to design; and the tower footing can be dismantled, can be used repeatedly for multiple times, is strong in adaptability, simple to dismantle and assemble, resources are saved and waste is reduced.

Description

technical field [0001] The invention belongs to the technical field of construction machinery, in particular to a detachable assembled tower base. Background technique [0002] There are nearly 300,000 building tower cranes in the country. The tower foundations have been continuously updated from the traditional cross-beam foundation, track foundation, square foundation, and pier foundation, but most of them are large-volume tower foundations that cannot be reused. The cost of a traditional one-time tower foundation is about 38,000 yuan / unit. If the penetration rate is 80% and the annual turnover is calculated, it will consume about 240,000 units×38,000 yuan / unit=9.1 billion yuan a year. [0003] The applicable conditions of different tower foundations can be classified into two types: 1. Tower foundations for small high-rise, high-rise and super high-rise towers, mainly with vertical force, with attachment devices, and various horizontal loads, overturning moments and torqu...
