Abstract: A conduit pipe is installed within a cable tunnel and telecommunication cables are disposed in the conduit pipe. The conduit pipe is divided longitudinally into a plurality of divided bodies. Each divided body is equipped at one longitudinal side with a retaining part and at the other longitudinal side with a protruded part. A single conduit pipe is formed when the divided bodies are connected to each other along the longitudinal side. Since the divided bodies can be wound around a small-diameter bobbin to be carried, the space for their custody is reduced and the carriage thereof is easier. Further, since connection parts on surfaces of the conduit pipes can be arranged such that they occupy empty spaces between conduit pipes, the space occupied by the connection parts can be minimized, thereby comparatively larger number of telecommunication cables being able to be disposed within the cable tunnel.

Abstract: Tubular components for use in modular fencing systems are manufactured utilizing die-forming of a flat plastic sheet, rather than by profile extrusion of a tubular form. This approach is made feasible by an aesthetically acceptable and structurally sound longitudinal edge joint configuration. The joint is formed by cooperating clip members formed along opposing longitudinal edges of the sheet. The clip members are interlocked with each other in overlapping relation following the die-forming operations. The clip members are substantially concealed by peripheral side portions of the component that are held in closely spaced or abutted relation. Structural integrity is assured by staking overlapping portions of the clip members to each other at longitudinally spaced locations. This can be accomplished with a thin circular blade having teeth that rotate to pass between the peripheral side portions and to press against and deform the overlapping portions, one into the other.
