Abstract
A noise barrier fence includes vertical eye section steel upright posts each presenting open channels facing along the length of the fence, horizontal rails located in these open channels and vertical boards fastened to the horizontals, the boards being butted side by side with the joints covered by small overlapping cover strips. The vertical boards also fit into the channels of the upright posts and their upper and lower ends are sandwiched between pairs of horizontal boards at the top and bottom of the fence. The construction is readily adapted to sloping ground and effectively closes all gaps through the fence.
Claims9
A barrier including a number of spaced upright posts, with inter-connecting horizontal rails and vertical boards, in which each of the upright posts is an integral rolled steel member of I-section providing grooves in opposite faces directed along the length of the fence, and the ends of the horizontal rails and the edges of adjacent boards, together with further vertical packing elements, are tightly fitted into the said grooves.
A barrier comprising a number of spaced upright posts with interconnecting horizontal rails and vertical boards, in which the lower ends of the boards are sandwiched between a pair of horizontal gravel boards extending along the bottom of the fence on opposite sides thereof, the said two boards being of different heights.
A barrier comprising a number of spaced upright posts with interconnecting horizontal rails and vertical boards, in which the lower ends of the boards are sandwiched between a pair of horizontal gravel boards extending along the bottom of the fence on opposite sides thereof, and the said posts are formed with vertical grooves in opposite faces extending in the direction of the fence and the ends of one of the said two gravel boards fit into the respective grooves.
A fence comprising a number of spaced upright posts with interconnecting horizontal rails and vertical boards, in which the upper ends of the said boards are received in a cap structure comprising two vertical flanges extending respectively along the opposite faces of the upper ends of said boards, the said flanges being of different vertical heights, and a unitary horizontal flange overlying the tops of the boards and being integral with said vertical flanges.
A barrier including a number of spaced upright posts with interconnecting horizontal rails and vertical boards, in which the boards are arranged closely adjacent side by side in non-overlapping relationship and at each joint between two boards a cover strip is secured by fastenings passing through the said joint between the said two boards.
