FIELD: construction engineering.
SUBSTANCE: hollow screw body is made of one circular-coiled strip with its turns being interconnected in the tips. The strip is bent along bend lines inclined to its edges to form along the external and internal surfaces the one-way multiangular pocket-shaped spirals and helixes. And the bend line distance is equal to the length of each multiangular element, and the pockets of the internal surface can differ from those of the external surface both in shape and dimensions.
EFFECT: technological enhancement.
