Synchronous construction platform and method for ultrahigh chimney cylinder and lining

WANG QUNWEI

The invention provides a synchronous construction platform and method for an ultrahigh chimney barrel and a lining. The construction platform comprises a chassis, a transition platform and a top platform; the center of the chassis is fixedly connected to a supporting frame extending in the vertical direction, and the supporting frame is provided with a first climbing mechanism and a second climbing mechanism which are distributed up and down at an interval; the transition platform and the top platform are both connected to the supporting frame in an up-down sliding and sleeving mode and connected to the first climbing mechanism and the second climbing mechanism respectively; and a plurality of open frames used for fixing an inner formwork and an outer formwork in a matched mode are distributed on a bottom frame of the top platform in a circumferential array mode. According to the synchronous construction platform for the ultrahigh chimney barrel and the lining, the chassis and the transition platform can be driven by the first climbing mechanism to climb upwards in sequence, so that the chassis and the transition platform are lapped and fixed on each layer of annular bracket step by step, overall ascending is realized, a climbing supporting rod is not needed, construction consumables can be reduced, the lining is convenient to build, and the whole body can settle to the ground after construction reaches the top.

本发明提供了一种超高烟囱筒体和内衬同步施工平台及方法，施工平台包括底盘、过渡平台，以及顶部平台；其中，底盘的中心固定连接有沿竖直方向延伸的支撑架，支撑架上设有上下间隔分布的第一爬升机构和第二爬升机构；过渡平台和顶部平台均上下滑动套接在支撑架上，且分别与第一爬升机构和第二爬升机构连接，顶部平台的底架上圆周阵列分布有多个用于配合固定内外模板的开字架。本发明提供的超高烟囱筒体和内衬同步施工平台，底盘和过渡平台能够在第一爬升机构的带动下依次向上爬升，从而逐级搭接固定在各层环形牛腿上，实现整体上升，无需爬升支撑杆，能够降低施工耗材，内衬砌筑方便，施工到顶后能够整体沉降至地面。
