GUARD FENCE CAPABLE OF BEING INSTALLED ON SLOPE

摘要

PROBLEM TO BE SOLVED: To provide a guard fence capable of being installed on a slope wherein a horizontal beam and a vertical piece can be fixed at a reference position of vertically crossing with each other and the angle of the vertical piece with respect to the horizontal beam can be adjusted according to the inclination of an installation site without applying a large force. SOLUTION: The guard fence is constituted by securing to erected struts a guard fence frame wherein a plurality of the vertical pieces 3 are turnably installed between the upper and lower horizontal beams 2. A horizontal frame 2 and the vertical piece 3 inserted into the horizontal frame 2 through a slot hole 5 made in the horizontal frame 2 are joined by a pin 4. The vertical piece 3 is secured to the vicinity of a first end part of the slot hole 5 so that the vertical piece 3 cannot be turned to the first end part side from the reference position due to interference of the vertical piece 3 with the first end part. The vertical piece 3 can be turned to the second end part side opposite to the first end part side until the vertical piece 3 gets into contact with the second end part on the opposite side.
