Description

Technical Field

[0001] The invention relates to an improvement of a suspension bridge installation technology, belongs to the field of bridges, and in particular to a combined roller type cable saddle. Background Art

[0002] A suspension bridge includes anchors, main cables, main towers, main cable saddles, and loose cable saddles. The anchors are mainly used to fix the main cables and provide a foundation for the main cable anchoring. The cable saddle is a structure specially designed for the suspension cables to pass around the top of the tower and change the direction of the main cables smoothly. The upper seat of the cable saddle is composed of rib-shaped cast steel blocks with cable grooves for placing the suspension cables. The cable saddle in the rigid bridge tower generally has a row of rollers under the upper seat and a lower seat bottom plate under the rollers to better distribute the concentrated load transmitted from the rollers on the tower column. The main cable saddle is used to support the main cable and smoothly change the direction of the main cable. It is generally located on the top of the main tower. At present, conventional suspension bridges are equipped with two main cables on the left and right. The two main cables on the left and right are respectively equipped with two independent main saddles, loose saddles and two anchor points. When the ambient temperature changes, the main cables will be displaced due to the thermal expansion and contraction effect; at the same time, wind and vibration will also cause dynamic displacement of the main cables. The existing saddles and anchors are fixed and cannot be moved, which to a certain extent limits the free displacement of the main cables, thereby generating additional additional forces in the main cables, resulting in excessive local stress in the main cables, excessive pressure on the saddles, and thus damage to the bridge structure.

[0003] The Chinese patent application with application number CN 202110358360.9 and application date April 1, 2021 discloses a ground-anchored suspension bridge structure suitable for special terrain, one end of which is fixed on a relatively flat shore and the other end is fixed on a steep shore, including a first force-bearing system, a second force-bearing system and a third force-bearing system; the first force-bearing system is composed of a main cable, a cable tower, a new roller-type cable saddle, a main cable saddle, a loose cable saddle, a tunnel-type anchor and a gravity anchor; the second force-bearing system is composed of a steel truss stiffening beam and a sling; the third force-bearing system is composed of a steel truss stiffening beam and a sling; The system consists of an anchor structure, vertical anchor cables, central cable stays and cable clamps. The first and second force systems participate in the overall force of the structure. The third force system bears the live load and transfers the load to the steel truss stiffening beam. This scheme is a novel structural form, strong spanning capacity, less excavation and blasting, short construction period, considerable economic benefits, and environmentally friendly suspension bridge type. However, it does not solve the problem that the main cable cannot move, so that the external force causes additional pressure on the main cable, affecting the safety of the bridge structure.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of this patent application, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in this field.
