A theft prevention cross beam of bridge railing is provided to absorb the impact applied to a cross beam dually through the cross beam cover and the cores beam fixing plate and to make the separation of the cross beam difficult so as to prevent theft. A theft prevention cross beam of bridge railing is composed of a crossbeam fixing plate(10) and a crossbeam cover(20) which are separately manufactured. A coupling hole(a) for connection of a post(A) is bored in a vertical plate(11) of the cross beam fixing plate. Narrow plates(12,13) are installed on the top and bottom of the vertical plate so that cross beam insertion grooves(14,15) are formed inside, and support plates(16,17) are made into one body. Fixing holes(18,19) are bored in the narrow plates and insertion pieces(22,23) are extended on the top and bottom of the cross beam cover, in which an opening(21) is formed, to be connected and fixed. |
