Large-area net rack overall incremental launching construction method
The invention relates to a large-area net rack overall incremental launching construction method. The large-area net rack overall incremental launching construction method comprises the steps that construction simulation analysis is carried out, and the jacking position and the stress condition of a net rack are determined according to an analysis result; the net rack is assembled on the ground; a jacking part is installed at each jacking position, and the assembled net rack is in butt joint with the jacking parts; the jacking parts comprise jacking bases and jacks erected on the jacking bases; the jacks are started to enable telescopic rods of the jacks to extend, then the net rack is jacked, standard knots are installed at the upper end of an existing formed jacking part, and the telescopic rods of the jacks are controlled to retract so that the jacks can move and be supported on the installed standard knot; the steps are repeated until the net rack is jacked to preset heights; and when the standard knots are installed on the existing formed jacking part one by one, an inclined supporting framework is installed according to the stress condition, and the inclined supporting framework is connected with the jacking parts. According to the large-area net rack overall incremental launching construction method, the net rack is convenient and fast to perform incremental launching construction and has better stability.
本申请涉及一种大面积网架整体顶推施工工法，包括：施工模拟分析，根据分析结果确定网架的顶升位置及受力情况；地面拼装网架；在每个顶升位置安装顶升构件，并将拼装完成的网架与顶升构件对接；顶升构件包括顶升底座及架设在顶升底座上的千斤顶；启动千斤顶以使得千斤顶的伸缩杆伸长，进而将网架顶升，将标准节安装至现有成形的顶升构件的上端，控制千斤顶的伸缩杆回缩，以使得千斤顶移动并被支撑在安装的标准节上；重复上述步骤，直至网架被顶升至预设高度；其中，在将标准节逐节安装至现有成形的顶升构件上时，根据受力情况安装斜支撑架构，斜支撑架构与顶升构件连接。通过上述设置，使得网架在顶推施工时方便快捷且具有更好的稳定性。
