Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
The present embodiment provides a cross beam assembly for connection with a main cable, connected with a main cable 1, comprising a cross beam 2 and an end fixing device 3. The longitudinal direction of the main cable 1 is used as the longitudinal direction.
Based on the strong tension capability of the main cable 1, as shown in fig. 1 and 2, the main cable 1 is used as a main load-bearing member. The two main cables 1 are parallel to each other and fixedly connected with external anchor seats positioned on two sides of a river bank through cable saddle anchors, and the anchor seats provide anchoring resistance for the main cables through prestressed anchor cables planted on rock strata, so that the main cables 1 have certain initial tension. The cross beams 2 are arranged at intervals along the length direction of the main cables 1, and meanwhile, two ends of each cross beam 2 are fixedly connected with the main cables 1 on two sides through end fixing devices 3 respectively; and then the bridge deck bearing plate is arranged on the cross beam 2 to form the bridge deck.
