Above-mentioned composite structure cable testing bridge strut rail, the stiffening rib of described cable testing bridge crosspiece inside is the two strip metal plates that are parallel to cable testing bridge crosspiece axis, sheet metal is vertical with cable testing bridge crosspiece square tube bottom surface, the top of sheet metal is pipe, the attachment screw of the internal diameter of pipe and cable testing bridge crosspiece is complementary, and the front-end face attachment hole of end face end socket is relative with the top pipe of stiffening rib.
Above-mentioned composite structure cable testing bridge strut rail, the rear and low part of described end face end socket connects a dull and stereotyped card, card is identical material integral production with the end face end socket, distance between distance between the bi-side of card and cable testing bridge crosspiece square tube two madial walls is complementary, in the middle of the card two vertical gap are arranged, two strip metal plates of stiffening rib bottom are clipped in the gap respectively.
Above-mentioned composite structure cable testing bridge strut rail, the thickness of the anticorrosive coat of described cable testing bridge crosspiece outside is 0.1-3mm.
The beneficial effects of the utility model are:
Cable testing bridge crosspiece of the present utility model is made by the section bar of composite structure, there is the sealing of end face end socket at the two ends of cable testing bridge crosspiece, cable testing bridge has been finished whole preservative treatment before the crosspiece assembling, solved whole anti-corrosion cable bridge cable testing bridge lateral wall and cable testing bridge strut rail joint in anticorrosion process and can not accomplish complete corrosion-resistant defective, the generation of the phenomenon such as prevented in use for some time cable testing bridge lateral wall and the joint corrosion of cable testing bridge strut rail of cable testing bridge, come off; When the cable testing bridge strut rail was connected with the cable testing bridge lateral wall, the attachment hole that attachment screw passes the end face end socket was connected in the pipe of stiffening rib, is connected firmly, and had increased the join strength of cable testing bridge strut rail and cable testing bridge lateral wall.
