Embodiment Construction
[0047] Below in conjunction with accompanying drawing, the present invention is described in detail.
[0048] 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.
[0049] Such as Figure 1-11 As shown, it is a schematic diagram of each component of the assembled cast tower base described in this embodiment, an assembled cast tower base, the cast tower base includes the bottom foot plate in contact with the ground, the ring plate 4 and the top of the base from bottom to top. Platform ring beam 1, the angle between the ring plate and the bottom foot plate is 10-30°; the bottom foot plate is ring-shaped, and the entire tower base is divided into four identical p...

Abstract
The invention discloses an assembled cast tower foundation. The cast tower foundation comprises a bottom foot plate contacted with the ground, an annular plate and a bearing platform ring beam at the top from bottom to top; an included angle between the annular plate and the bottom foot plate is 10-30 degrees; the bottom foot plate is annular; the whole tower foundation is divided into four identical parts along an axial section; and the four parts are annularly assembled as a whole in use. The assembled cast tower foundation is characterized in that the surface of the annular plate is arched; and the center of the bearing platform ring beam is perforated, so that a through hole is formed in the tower foundation in the vertical direction from top to bottom. The tower foundation is balanced and stabilized according to designed pressure / counterweight. The tower foundation can be disassembled and recycled by multiple times, can be suffered from thousands of collision to achieve high adaptability, is high in recycling value, is simple and fast in disassembly, transportation and installation, saves resources, reduces wastes, and accords with green construction requirements.
Description
technical field [0001] The invention belongs to the technical field of construction machinery, in particular to a detachable and assembled casting tower base. Background technique [0002] There are nearly 300,000 building tower cranes in the country. The tower foundations have been continuously updated on the basis of traditional cross-beam foundations, track foundations, square foundations, and pier foundations, but most of them are large-volume tower foundations that cannot be reused. The cost of the traditional one-time cast-in-place tower base is about 26,000 yuan / unit, and it will be scrapped once it is used, leaving obstacles underground. It will cost 12,000 yuan / unit to remove it, and at least 38,000 yuan / unit will be required for the whole tower, of which 10 tons / unit of cement will be used. Platform, gravel 75 tons / set, steel 1.5 tons / set. If it is popularized to 80% and turns over once a year, about 300,000 units x 0.8 x 38,000 yuan per unit = 9.1 billion yuan wi...
