A length control type steel pipe strut is provided to carry and operate easily by using a steel pipe strut as a strut and regulating the length of a steel pipe strut, to reduce an economic loss by recycling a steel pipe strut at sheathing work and to simplify field assembly work by having no necessity for processing a long steel pipe strut in a field. The invention relates to a length control type steel pipe strut capable of regulating the length of a steel pipe strut by forming steel pipe struts(100,300) on the two sides to be slidable from a steel pipe strut(200) on the center. The two steel pipe struts have enough diameters to be inserted to the center steel pipe strut, and a two-side frictional joint structure is formed by fixing nuts to the inside of the two steel pipe struts having a small diameter with a pipe-shaped connector(400) and a fastener(500), inserting to the center steel pipe strut having a large diameter and passing bolts through the steel pipe struts of two sides or the steel pipe strut of the center to have sufficient structural stiffness against compression of the steel pipe struts. |
