Thin-wall steel cylinder concrete tower

Abstract

The invention relates to a thin-wall steel cylinder concrete tower. The thin-wall steel cylinder concrete tower comprises a tower cylinder which is formed by a plurality of cylinder wall sheets connected in an end-to-end mode. All the cylinder wall sheets are arranged vertically and are of a cavity structure which is provided with the hollow inside and the open upper and lower ends. The side ends of every two adjacent cylinder wall sheet structures are connected and fixed to each other, and every two adjacent cylinder wall sheet structures communicate with each other via through holes formed in the side ends correspondingly. A reinforcing rib structure is arranged between the inner wall and the outer wall of each cylinder wall sheet structure, and concrete is injected between the inner wall and the outer wall of each cylinder wall sheet structure. A plurality of outer prestress steel strands are vertically arranged on the inner wall of the tower cylinder. The thin-wall steel cylinder concrete tower has the beneficial effects that the structure is simple, assembly is convenient by means of the split type design, the whole tower can be cast in place and can also be prefabricated and installed, the construction period is short, and the engineering cost is low; the reinforcing rib assemblies can enhance the rigidity of the cylinder wall sheet structures, transportation, installation and casting are convenient, and the reinforcing rib assemblies can replace part of concrete reinforcing bars; and the whole device has high structure strength and good safety performance.

Description

technical field [0001] The invention relates to the technical field of steel tube concrete towers of wind power generator sets, in particular to a thin-walled steel tube concrete tower provided with reinforcing ribs. Background technique [0002] Wind power generation equipment has become more powerful and can be applied to low wind speed wind farms. It is more feasible to increase the height of the hub to obtain high-altitude wind resources than to increase the sweeping area of ​​the blades. As the main load-bearing part of the wind turbine, the tower is subjected to various loads, and it is a key factor to ensure the normal operation of the wind turbine. As the height of the tower continues to increase, the importance of the tower in the design and manufacture of wind turbines is also increasing. [0003] The wind turbine tower is subject to a variety of loads. In addition to supporting the weight of the wind turbine nacelle, generator and hub, it must also bear the dynam...
