Abstract

This product is a component that constitutes a vertical shaft. The cross section of the corrugated steel is shaped to have high rigidity, and the reinforcing main girders attached to the flanges are bolted to improve the strength and ease of construction when constructing the shaft. In the oblique and front views, the multiple rods attached to the front of the corrugated steel are spacing retainers.
