The device according to the invention consists in the fact that the outer surface is protected by a robust outer envelope and a filling material between the component to be coated and the outer envelope.
摘要:
Method of constructing a cable-stayed bridge whose deck (1) is composed ofwo parallel series of voussoirs connected together by connecting members known as deltas (7) which carry at their top part (8) the anchorage points for the cable stays (12). When they are placed in position the bottom parts (9) of the successive deltas are fastened to rigid filling members (14), and auxiliary prestressing cables (13) are preferably installed which connect the top part (8) of a delta to the bottom part (9) of the following delta (7), said cables being approximately in line with the cable stays.
摘要:
Bridge comprising a bridge floor, said floor consisting of an upper boom (4) which may form a road section, a lower boom (5) which may be formed by a tubular succession of sections, and diagonal linking girders (6), joining the booms, their axes converging on that of the lower boom. Those elements subjected to high stress are preferably to be provided with individual pretensioning elements. The gussets (15) linking the diagonals with the upper boom carry advantageously the attachment elements of the supporting stay cables (2).
