Description

Adjustable polygonal mixed tower barrel template and tower barrel segment manufacturing method

Technical Field

The invention relates to the technical field of manufacturing of concrete tower cylinder pipes of wind driven generators, in particular to an adjustable polygonal mixed tower cylinder template and a manufacturing method of tower cylinder pipes.

Background

At present, the main structural form of the wind power concrete tower barrel adopts a whole ring or segmented (2-4) segments, the main reason is that the segments are limited by connecting and splicing nodes and pouring templates, the connecting nodes are too many due to too many segments, the later inspection and maintenance cost is high, the rigidity and the manufacturing precision of the templates need to be improved in order to control deformation during segmented maintenance, and therefore the investment cost of the templates is high.

The template that concrete tower adopted among the wind generating set at present is customized usually, and the tower section of thick bamboo diameter, tower section of thick bamboo wall thickness, the tapering of tower section of thick bamboo that pour are the constant value promptly, can't adjust according to the power size of unit, the height of fan, the frequency demand of fan, and the tower market adaptability that this kind of template produced is relatively poor, and there is almost no adjustment space after the template is stereotyped.

The reason is analyzed, and the thickness, the angle, the height and the width of the template adopted when the duct piece is poured can not be adjusted, so that one template can only produce the duct piece of one concrete tower barrel.
