Arch type steel-concrete combined ceiling structure of large-span giant underground workshop and construction method
The invention discloses an arch type steel-concrete combined ceiling structure of a large-span giant underground workshop and a construction method. The arch type steel-concrete combined ceiling structure absorbs the advantages of a steel structure and a concrete structure, has the advantages of being high in bearing capacity, high in corrosion resistance, good in fireproof performance and the like, and is rapid in installation and convenient to construct. The installed steel structure is also used as a formwork during concrete pouring, steel bar binding is not needed, and therefore construction interference is small, efficiency is high, and the construction period is short. The arch type steel-concrete combined ceiling structure structurally comprises a ceiling supporting system, a ceiling arched beam and a ceiling bottom plate. The ceiling arched beam is erected and fixed through the ceiling supporting system. The ceiling supporting system comprises ceiling supporting columns arranged on the upstream side and the downstream side, ceiling anchor rods and lengthening pull rods, wherein the two ends of the ceiling arched beam are erected on the tops of the ceiling supporting columns; the top ends of the ceiling anchor rods are anchored into a top arch rock mass; the two ends of the lengthening pull rods are connected with the ceiling anchor rods and the ceiling arched beam correspondingly; and the ceiling bottom plate is laid above the ceiling arched beam.
本发明公开了一种大跨度巨型地下厂房拱式钢‑混凝土组合吊顶结构及施工方法，吸取了钢结构和混凝土结构各自的优点，不仅具有承载能力强、抗腐蚀能力强、防火性能好等优点，而且安装快捷、施工方便，安装好的钢结构兼作浇筑混凝土时的模板，无需绑扎钢筋，因而施工干扰小、效率高、工期短。其结构包括吊顶支撑系统、吊顶拱梁和吊顶底板，吊顶拱梁通过吊顶支撑系统架设并固定，所述吊顶支撑系统包括由设置于上下游两侧吊顶支撑柱、吊顶锚杆和接长拉杆，吊顶拱梁的两端架设于吊顶支撑柱的顶部，所述吊顶锚杆的顶端锚入顶拱岩体，接长拉杆两端分别连接吊顶锚杆和吊顶拱梁，吊顶底板铺设于吊顶拱梁上方。
