Large-span assembly type combined arched heavy roof structure and construction method thereof
The invention provides a large-span assembly type combined arched heavy roof structure and a construction method thereof, and relates to the technical field of building design, a lower supporting structure is mounted, and prestress is applied to a supporting frame connected with a steel-concrete combined arch rib, so that the supporting frame generates inward contraction deformation under the action of the prestress; a steel-concrete combined arch rib is hoisted above the lower supporting structure; inter-arch connecting beams are installed on the steel-concrete combined arch ribs in the first direction; concrete is poured in the steel-concrete combined arch rib in the second direction, and a roof panel is formed in the second direction; the steel-concrete combined arch rib comprises a box-type steel arch with an overhanging flange and a concrete arch filled in the box-type steel arch. The condition that the span exceeds 60 meters can be achieved, the construction difficulty is small, the safety risk is low, and the cost is low.
本发明提供一种大跨度装配式组合拱形重屋顶结构及其施工方法，涉及建筑设计技术领域，安装下部支承结构，对与钢‑混凝土组合拱肋连接的支撑框架施加预应力，使支撑框架在预应力的作用下产生向内收变形；在下部支承结构上方吊装钢‑混凝土组合拱肋；在钢‑混凝土组合拱肋上沿第一方向安装拱间联系梁；沿第二方向在钢‑混凝土组合拱肋内浇筑混凝土，沿第二方向形成屋面板；钢‑混凝土组合拱肋包括：带有外伸翼缘的箱型钢拱以及填充在箱型钢拱内的混凝土拱。本发明可以实现跨度超过60米的情况，且施工难度小，安全风险低，成本低。
