ケーブル保護管及びケーブル保護管路

Japanese Patent JP7271153

B2

To provide a cable protection pipe capable of preventing rotation of a separator relative to a central axis of a straight pipe, easily chamfering an inner peripheral surface of the straight pipe and capable of fabricating end parts of the straight pipe into a desired shape.SOLUTION: A cable protection pipe 102 comprises a straight pipe 101 and a separator 120 that compartmentalizes an inner space of the straight pipe in the vertical direction. The separator comprises a separating section 122 extending in the lateral direction in a cross-section orthogonal to a central axis 110, and leg parts 162-1, 162-2 descending from both sides of the separating section in the lateral direction along an inner peripheral surface 105 of the straight pipe. A corner whose cross-section is convex outward in a radial direction of the straight pipe is formed at a position where the lower end of the leg part touches the inner peripheral surface. The corner is composed of an inner peripheral surface on the upper side relative to the corner and an inner peripheral surface located on the lower side relative to the corner. The inner peripheral surface on the upper side which forms the corner in its cross-section extends in the vertical direction, and the inner peripheral surface on the lower side which forms the corner is inclined toward the central axis side of the straight pipe relative to the vertical direction.SELECTED DRAWING: Figure 3
