A suspension bridge scatter cable saddle

Abstract

The invention discloses a splay saddle of a suspension bridge. The splay saddle comprises a saddle body and a compression beam, wherein the saddle body comprises a U-shaped saddle groove; one end of the saddle groove faces to an anchorage and is in an externally expanded arc-shaped conical surface structure; a plurality of baffles are arranged in the saddle groove of the saddle body at intervals; one end of the compression beam faces to the anchorage and is in an externally expanded arc-shaped conical surface structure; the compression beam is fixed on the top of the saddle body through a plurality of fastening bolts; the top of the saddle groove of the saddle body is plugged by the compression beam; and one end of the whole splay saddle faces to the anchorage and is in a horn mouth structure expanding from inside to outside gradually. With the adoption of the splay saddle of the suspension bridge, symmetrical splay structures are ensured to be arranged in a horizontal direction and a vertical direction of the splay saddle under the premise that a cable strand can be easily and conveniently anchored, so that not only is reliable and stable floating realized, but also the excavated volume on the anchorage is low, and the manufacturing cost of the suspension bridge is effectively reduced.

Description

technical field [0001] The invention relates to a main cable erecting member of a suspension bridge, in particular to a loose cable saddle of a suspension bridge. Background technique [0002] The main load-bearing component of the suspension bridge is the main cable, and the reliability of the anchorage of the main cable on the anchorage directly determines the safety of the suspension bridge. In order to ensure the anchoring reliability of the main cable on the anchorage, it is usually realized by enlarging the anchorage area of ​​the main cable, that is, the main cable is divided into several divergent strands by using loose cable saddles, and each strand is Anchoring on the anchorage. [0003] see Figure 1 to Figure 5 : The traditional loose cable saddle is mainly composed of a saddle body 01 and a compression beam 04; the saddle body 01 has a saddle groove in a "U" shape, and the end of the saddle groove facing the anchor is an outwardly expanding arc-shaped conical s...

AI Technical Summary

Problems solved by technology

However, since the above-mentioned scatter saddle only has a single downward divergent structure in the vertical direction, the component force of the cable strand 06 in the vertical direction is always downward, and the downward component force needs to rely on sliding or swinging. base 07 for balancing (eg Figure 4 shown), in this case, it is necessary to design and process the base while designing and processing the loose cable saddle, which will inevitably increase the construction cost of the suspension bridge; in addition, because there is only a single downward divergent structure in the vertical direction, the entire anchorage body 08 The lower part of the anchorage body 08 not only limits the arrangement of other structures under the anchorage body 08, but also will inevitably cause a large amount of excavation of the anchorage body 09 (such as Figure 5 shown), further greatly increasing the construction cost of the suspension bridge
