Abstract

Abstract A warning, marking and/or barrier arrangement in which trestle barriers, barrier planks and mountings for signboards are combined into units for warning, marking and/or barring purposes. A trestle barrier is constructed of plastic material and has the shape of a hollow double pyramid. The latter has a hollow connecting web, and the parts are arranged on a hollow support. The top of each pyramid has grooves extending in two normal directions. The barrier planks have plugs or recesses at their end portions, as well as holes and/or mountings for the placement of signboards. The mountings are adapted to the grooves in their lowermost portions, and have lugs in their center portions. In the upper portions, the mountings are provided with a hole to which a slide bar is secured. This slide bar has a slot and an upper edge shaped to engage over the edge of a sign board. The top of each pyramid is removably and pivotally mounted on the remaining part of the trestle barrier.
