Semi-automatic protective shed frame used during viaduct construction across railway and erecting method
The invention discloses a semi-automatic protective shed frame for viaduct construction across a railway and an erecting method. The shed frame comprises a half shed frame assembly. The half-range shed frame assembly comprises main stand columns, a half-width type profile steel ceiling and side nets, each main stand column comprises an inner sub-column, an outer sub-column and a top cover, and main sliding grooves are formed in the main stand columns. A main shaft of the half-width type section steel ceiling is matched in the two main sliding grooves in a sliding manner; the top cover is provided with a full-circle shaft hole; a trolley is arranged at the top end of the main stand column and internally provided with a gear ring. Each end of the main shaft is provided with a gear; a wedge-shaped cushion block is arranged on a top beam of the half-width type section steel ceiling; top hard rods of the side nets are rotatably connected with the main shaft, and bottom hard rods of the sidenets are provided with limiting convex beams; and the main stand column is provided with limiting blocks. The method is characterized in that installation of a side structure is completed while the half-width type section steel ceiling is lifted up, and the half-width type section steel ceiling is rotated through a trolley gear ring to abut against each other. According to the shed frame and theerecting method, a crane does not need to be used for hoisting the profile steel ceiling above the rail.
本发明公开了一种跨越铁路的高架桥施工时用的半自动防护棚架及搭设方法，该棚架包括半幅棚架组件；半幅棚架组件包括主立柱、半幅式型钢顶棚和侧网，每根主立柱包括内分柱、外分柱和顶盖，主立柱设有主滑槽；半幅式型钢顶棚的主轴滑动配合在两主滑槽内；顶盖设有整圆轴孔；主立柱顶端设有小车，小车内部设有齿圈；主轴每端设有齿轮；半幅式型钢顶棚的顶梁上设有楔形垫块；侧网的顶部硬杆与主轴可转动连接，侧网的底部硬杆设有限位凸梁；主立柱设有限位块；该方法的关键在于：上提半幅式型钢顶棚同时完成侧部结构的安装，且利用小车齿圈旋转半幅式型钢顶棚使其相互抵靠。该棚架及搭设方法无需使用吊机从铁轨上方吊运型钢顶棚。
