Forked steel box arch rib and construction method thereof
The invention discloses a forked steel box arch rib and a construction method thereof. The forked steel box arch rib comprises a first single-limb arch rib, a second single-limb arch rib and a combined arch rib, and a gap is formed between the first end of the first single-limb arch rib and the first end of the second single-limb arch rib; a small gap not larger than 6 cm exists between the second end of the first single-limb arch rib and the second end of the second single-limb arch rib, and the second end of the first single-limb arch rib and the second end of the second single-limb arch rib are both fixedly connected with the first end of the combined arch rib, that is, the first single-limb arch rib, the second single-limb arch rib and the combined arch rib form a herringbone structure. The mode that the two inner side webs and the middle web are in butt welding is adopted, effective transmission of web force is achieved, the full-length continuity of various plates of the forked steel box arch rib is guaranteed to the maximum extent, the forked point connecting structure does not need to be specially provided with local stiffening plates, the number of weld joints is reduced, the construction steps are simplified, the construction difficulty is reduced, and the construction efficiency is improved. The landscape effect that the two steel box arch ribs are completely tangent and combined into the single steel box arch rib is achieved while the structural stress is met.
本发明公开了一种分叉式的钢箱拱肋及其施工方法，包括第一单肢拱肋、第二单肢拱肋和合并拱肋，且第一单肢拱肋的第一端与第二单肢拱肋的第一端之间设置有间隙；第一单肢拱肋的第二端与第二单肢拱肋的第二端之间有不超过6cm的微小间隙，且均与合并拱肋的第一端固定连接，即第一单肢拱肋、第二单肢拱肋和合并拱肋构成“人”型结构；本发明采用两道内侧腹板与一道中间腹板对接焊的形式，实现了腹板力的有效传递，最大限度保证了分叉钢箱拱肋各类板件的通长连续性，分叉点连接构造无需特别设置局部加劲板件，减少了焊缝的数量，简化了施工步骤，减小了施工难度，在满足结构受力的同时，实现了两肢钢箱拱肋完全相切结合成单肢钢箱拱肋的景观效果。
