Abstract

The utility model belongs to wind power equipment, in particular to a wind power tower without a foundation ring. The wind power tower without the foundation ring comprises a first concrete layer (8), a second concrete layer (7) and a tower bottom section (4); a splicing upper flange (3) is fixedly installed on the tower bottom section (4), reinforcing ribs (2) are fixed to the tower bottom section (4) and the splicing upper flange (3) for reinforcement, the lower ends of ground anchor bolts (5) are embedded in the first concrete layer (8), wherein the ground anchor bolts (5) are installed in a splicing lower flange (1) and the splicing upper flange (3) in a penetrating mode respectively and fixed through nuts (6) in a locked mode, and the upper ends of the ground anchor bolts (5), the splicing lower flange (1), the splicing upper flange (3), the nuts (6) and the reinforcing ribs (2) are all embedded in the second concrete layer (7). By the improvement of a traditional foundation ring installation process, a first tower section is installed directly, so that installation steps are reduced, and the number of forged flanges is reduced by one.

Description

Foundation-free ring wind power tower

Technical field

The utility model belongs to wind power plant, particularly a kind of foundation-free ring wind power tower.

Background technology

Wind-power electricity generation is the renewable energy resource of tool practicality potentiality in new forms of energy, wind-force pylon is one of wind-power electricity generation equipment chief component, wind power tower is generally comprised of discharge ring and three sections of shell rings, during construction by the Installation and Debugging of discharge ring part qualified rear with concreting to basis, other shell ring is installed on top, the weak point of this kind of structure is subject to the restriction of discharge ring field time while being to construct, the impact of evolution during discharge ring installation after-pouring concrete, and the secondary of installing after discharge ring is built duration impact etc.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of convenient installation is provided, and reduces installation period, and can reduce the foundation-free ring wind power tower of manufacturing cost.

The technical scheme that the utility model technical solution problem adopts is: foundation-free ring wind power tower comprises section at the bottom of first floor concrete, second layer concrete, pylon, being characterized in splicing upper flange is installed at the bottom of pylon in section, at the bottom of reinforcing rib is fixed to pylon, section is reinforced with splicing on upper flange, implant in first floor concrete ground anchor bolt lower end, ground anchor bolt is installed on respectively on splicing lower flange and splicing upper flange and nut check is fixed, and ground anchor bolt upper end, splicing lower flange, splicing upper flange, nut, reinforcing rib are all implanted in second layer concrete.

The beneficial effects of the utility model are: utilize the technique of conventional mounting discharge ring to be improved, become direct installation first paragraph pylon, reduce fixing link and save a slice forged flange.
