Construction method of super-large-span dry coal shed grid structure
The invention provides a construction method of a super-large-span dry coal shed grid structure, which comprises the following steps of: laying a sliding track, and arranging a plurality of rolling bearings vertical to the track direction on the sliding track at intervals; an operation platform used for construction of the dry coal shed grid structure is arranged at the end of the sliding rail; construction of all the net rack units is conducted on the operation platform in sequence, the constructed net rack units slide by a preset distance in the direction away from the operation platform along the rails, and after the net rack units of a certain net rack module are constructed and spliced in a sliding mode, the net rack module slides to a preset position along the sliding rails through the rolling bearings on the sliding rails; through the design of the linear rolling bearings, surface-to-surface friction between a net rack support and a steel rail in a traditional sliding construction technology is changed into rolling friction between the net rack support and a track beam by the bearing rods, so that the sliding friction resistance is effectively reduced, the construction procedures are optimized, the construction procedures of mounting and dismounting the sliding steel rail are omitted, and the construction efficiency is improved. And a net rack hydraulic jacking in-place procedure is omitted, and the construction efficiency is improved.
本发明提供了一种超大跨度干煤棚网架结构施工方法，铺设滑移轨道，所述滑移轨道上间隔设有多根垂直于轨道方向的滚动轴承；在滑移轨道的端部设置用于干煤棚网架结构施工的操作平台；在操作平台依次进行各网架单元施工，完成施工的网架单元沿轨道向远离操作平台的方向滑移预设距离，待某一网架模块的网架单元施工且滑移拼接后，此网架模块利用滑轨上的滚动轴承沿滑轨滑移到预设位置；本发明通过直线滚动轴承的设计，将传统滑移施工技术中网架支座与钢轨之间的面与面之间摩擦变成轴承棒在网架支座与轨道梁之间滚动摩擦，有效的减小了滑移摩阻力，优化了施工工序，取消滑移钢轨安装和拆除施工工序，取消网架液压顶升就位工序，提高了施工效率。
