Upper-layer and lower-layer steel truss web member composite beam suitable for urban overhead and construction method of upper-layer and lower-layer steel truss web member composite beam
The invention discloses a construction method suitable for an upper-layer and lower-layer steel truss web member composite beam of an overhead in an urban area, and solves the problem that in the prior art, upper and lower chord members and upper and lower bridge decks are converted into prestressed concrete structures by a large-span truss beam, and stress is complex. The structure comprises an upper-layer panel and a lower-layer panel, the upper-layer panel and the lower-layer panel are connected through a plurality of web members which are evenly arranged, an anti-collision guardrail is arranged on the upper portion of the upper-layer panel, an upper chord member used for fixing the upper portions of the web members is arranged in the upper-layer panel, a lower chord member used for fixing the web members is arranged in the lower-layer panel, and pier columns are arranged on the lower portion of the lower-layer panel. A bearing platform is arranged on the lower portion of the pier column, and a pouring pile is arranged on the lower portion of the bearing platform. The structure is stable, the construction efficiency is high, the steel consumption of the steel truss web members is small, materials are saved, the occupied construction area is small, the plate buckle support material consumption is small, and the construction period is short.
本发明公开了一种适用于市区高架上下两层钢桁腹杆组合梁的施工方法，解决了现有技术中大跨度桁架梁将上下弦杆、上下桥面板转换为预应力混凝土结构，受力复杂的问题。本发明包括上层面板和下层面板，上层面板与下层面板之间通过若干均匀设置的腹杆连接，上层面板的上部设有防撞护栏，上侧面板内设有与用于固定腹杆上部的上弦杆，下层面板内设有用于固定腹杆的下弦杆，下层面板的下部设有墩柱，墩柱的下部设有承台，承台下部设有浇灌桩。本发明结构稳定，施工效率快，钢桁腹杆用钢量少，节约材料，施工占地少，盘扣支架材料用量少，工期快。
