Problems solved by technology

[0003] However, in general conventional ground-anchored suspension bridges, it is necessary to build bulky anchors to anchor the main cable, which results in a very large amount of foundation work for the anchorage structure in places with poor geological conditions, which often becomes a difficult point in the project; The anchorage and anchorage foundation of the anchor suspension bridge occupy a considerable part of the project cost, and become an important aspect affecting the structural economy of the suspension bridge; in urban areas or tourist areas, the construction of bulky anchorages will also have a negative impact on the aesthetics of the environment

Abstract

The invention discloses an inner self-anchorage suspension bridge. The inner self-anchorage suspension bridge is mainly composed of main cables, slings, cable bent towers, oblique columns, horizontal rods, auxiliary piers and a main beam. The end portion of each main cable is sequentially wound around a cable saddle at the top of the corresponding cable bent tower, a steering block I at the end portion of the corresponding horizontal rod, a steering block II at the bottom of the corresponding cable bent tower and a steering block III at the bottom of the corresponding oblique column and then anchored to the main beam. Each oblique column and the corresponding horizontal rod are arranged on the two sides of the corresponding cable bent tower and have one common end point which is arranged at the middle point of the corresponding cable bent tower. By the adoption of the inner self-anchorage suspension bridge, anchorages large in size are removed, the calculated length of the main cables for connecting the anchorages is reduced, and the stress and the amplitude of the main cables under the dead load effect are reduced; the cables are wound around cable bent tower foundations, and compared with an original ground anchor suspension bridge, the pressure applied to a foundation by the cable bent towers is reduced; the cables are installed and fixed to the main beam, the main beam supplies the axial force to balance part of horizontal components of the cables, the anti-wind performance of the suspension bridge is improved, meanwhile, the foundation horizontal thrust is reduced, and investment is reduced; and compared with an self-anchorage suspension bridge, the suspension bridge has the span much larger than that of the self-anchorage suspension bridge.

Description

technical field [0001] The invention belongs to a suspension bridge, in particular to an internal self-anchored suspension bridge. Background technique [0002] The suspension bridge structure has the characteristics of good mechanical performance, large spanning capacity, light and beautiful appearance, strong earthquake resistance, various structural forms, and good adaptability to terrain. It is often used as a Preferred bridge type. Therefore, people have also designed various suspension bridge structures. For example, Chinese patent application No. 201510012845.7 discloses a suspension bridge with high torsional rigidity, including a main girder, a cable tower, a main cable and a suspender. The two sides are used to suspend the main girder through the main cable, so that the main cable, boom and main girder form a structure with a triangular cross-section in space; the present invention utilizes the stability of the triangle to form a structure similar to a triangular...
