Problems solved by technology

That is, when prestressing the prestressed tendon at the uppermost part, a large stress concentration occurs at the uppermost and lower fixing parts, resulting in local failure.
[0007] Moreover, when prestressing needs to be reapplied due to prestress loss after construction, if prestressing tendons are only applied to the uppermost end as mentioned above, it will be due to the upper part of the generator set (Turbine) and the like. The structure interferes and is not easy to reapply the prestress

Embodiment Construction

[0033] The present invention relies on the multi-stage prestressed modular wind power tower to be stacked and assembled into a wind power tower by a plurality of modules that are prestressed through internal prestressed tendons. The above modules include: a plurality of stacked modules with prestressed tendons running through Tendon; a plurality of stretching modules, having a stretching introduction part through which the prestressing tendon is penetrated and the prestressing tendon is stretched and placed.

[0034] That is, in the present invention, modules are stacked to form a wind tower and a plurality of tensile modules are arranged among the stacked modules, so that prestress is not only applied to the uppermost end, but also prestress is applied in a multi-stage manner to prevent stress from concentrating on a specific area. position for structural stability.

[0035] Moreover, the above-mentioned module includes a concrete part constituting the main body and a hollow ...

Abstract

A modular wind power tower using multi-stage prestressing tendons of the present invention is assembled by stacking a plurality of modules prestressed by interior tendons. The modules comprise: a plurality of stack modules through which the interior tendons penetrate; and a plurality of tension modules which are comprised of a tension induction unit capable of applying tension to the tendons and fixing the tendons passing through the inside of the tension induction unit.

Description

technical field [0001] The present invention relates to a prestressed modular wind power tower. More specifically, the present invention applies prestress to multiple locations of stacked and assembled modular wind power towers by means of a multi-stage prestressed modular wind power tower In order to prevent stress concentration, prestress is applied to the hollow part of the module and installed, so that maintenance management such as reapplying prestress can be easily performed. Background technique [0002] Generally speaking, as the main structure of the wind turbine, the wind tower supports the wind rotor blades and the nacelle, and is mainly made of steel pipes. In particular, wind power towers of large steel pipes are manufactured through complex fabrication processes after many welding processes. That is, when manufacturing a large-scale steel pipe wind power tower, due to the influence of factors such as its own weight, the workability is significantly reduced. M...
