BEAM MATERIAL FOR GUARD RAIL AND CONNECTING STRUCTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To more effectively prevent adhesion of beam materials adjacent to each other by inserting a metal piece in a gap of a joint part where crest parts and valley parts are overlayingly engaged with each other.

SOLUTION: In a guard fence for a road where the beam materials 42 are joined to the supports erected at predetermined spaces, when the two corrugated beam materials 42 adjacent to each other are connected to each other with the crest parts 61 and the valley parts 62 overlaid in the longitudinal direction, both right and left ends of the beam materials 42 are cut obliquely at the same angle to the horizontal direction and also linearly.
