Installation and construction method for skylight keel of inner roof of large-span structure
The invention discloses a large-span structure inner roof skylight keel installation and construction method. The method comprises the following steps that S100, an assembly jig frame is installed; s200, roof structure upper-layer purlines are installed, and lower-layer purlines are in place in a jig frame; s300, mounting upper and lower full-length cross beams and skylight facade small splicing units; step S400, connecting and mounting the main and secondary structural beams of the skylight; step S500, arranging a lifting system; step S600, overall lifting is carried out; and S700, the rod piece is inlayed. According to the structural characteristics of an arc-shaped truss inner court and a connecting truss area between an outer side arc-shaped truss and a floor arch, an arc-shaped truss inner court skylight is segmented according to a primary truss, the outer side connecting truss area is segmented according to a secondary truss, and segmented small splicing units are assembled and welded on the ground through a jig frame. The integral lifting is realized by repeatedly changing the stress direction through the electric winching and the fixed pulley.
本发明公开了一种大跨度结构内屋面天窗龙骨安装施工方法，包括以下步骤：步骤S100、拼装胎架安装；步骤S200、屋面结构上层檩条安装、下层檩条胎架内就位；步骤S300、上下通长横梁、天窗立面小拼单元安装；步骤S400、天窗主次结构梁连接安装；步骤S500、提升系统布置；步骤S600、整体提升；步骤S700、嵌补杆件。根据弧形桁架内庭及外侧弧形桁架与落地大拱之间连系桁架区结构特点，将弧形桁架内庭天窗根据主桁架分段，外侧连系桁架区根据次桁架分段，将分段的小拼单元在地面使用胎架组装焊接完成，借助电动绞磨及定滑轮多次转换受力方向而整体提升。
