Closed steel structure of double-cable-coil spoke arch coal shed
The invention discloses a closed steel structure of a double-cable-coil spoke arch coal shed. The closed steel structure comprises spoke arch closed steel, a longitudinal coupling beam and an arch reticulated shell, the spoke arch closed steel comprises a steel arch, at least seven prestressed inhaul cables and two cable coils (a) and (b) which are symmetrically arranged on the same horizontal plane along the central axis of the steel arch, the cable coil (a) and the cable coil (b) are connected through the prestressed inhaul cables, and the cable discs (a) and (b) are respectively connected with the steel arch through at least three prestressed cables; and the two closest prestressed inhaul cables of the steel arch and the cable discs (a) and (b) are arranged in a crossed mode, and the two closest prestressed inhaul cables and the second adjacent prestressed inhaul cable on the other cable disc are connected to the same point of the steel arch. According to the closed steel structure of the double-cable-coil spoke arch coal shed, on one hand, the rigidity and the bearing capacity of the steel arch can be greatly improved, and the sensitivity of the steel arch to geometric initial defects is reduced; and on the other hand, the double-cable-disc design can enlarge the indoor space, the requirement of the technology for indoor clearance is easily met, and the structure is more suitable for a large-span coal shed.
本发明公开了一种双索盘车辐拱煤棚封闭钢结构，包括车辐拱封闭钢、纵向连梁及拱形网壳，所述车辐拱封闭钢包括钢拱、至少7根预应力拉索及沿钢拱中轴线对称布置于同一水平面上两个索盘(a)、(b)，所述索盘(a)与索盘(b)通过预应力拉索连接，所述索盘(a)、(b)分别通过至少三根预应力拉索与钢拱连接；所述连接钢拱与索盘(a)、(b)的预应力拉索中最邻近的两根成交叉布置，且分别与另一索盘上的第二邻近的预应力拉索连接在钢拱上的同一点。本发明所述双索盘车辐拱煤棚封闭钢结构，一方面可以大幅提高钢拱的刚度和承载力，降低钢拱对几何初始缺陷的敏感性；另一方面，双索盘设计可以扩大室内空间，易于满足工艺对室内净空的要求，更适用于大跨度煤棚。
