Mounting method of large-span annular pressure ring single-layer grid steel roof
The invention discloses a mounting method of a large-span annular pressure ring single-layer grid steel roof. The large-span annular pressure ring single-layer grid steel roof is mounted on a plurality of steel columns. The mounting method comprises the following steps of firstly, mounting an outer ring steel beam on the steel columns, and then mounting a supporting bearing platform according to the mounting position of a pressure ring, wherein at least three supporting units are arranged, all the supporting units are located below the pressure ring and evenly distributed along the circumference of the pressure ring, and every two adjacent supporting units are connected through a connecting rod. Each supporting unit comprises a base, supporting frames arranged on the base and top bearing platforms arranged at the top end of the supporting frame, wherein the supporting frames are formed by arranging a plurality of standard sections up and down; and then a jack is placed on each top bearing platform of a supporting bearing platform, the pressure ring is placed on the jack, the working height of the jack is adjusted to enable the pressure ring to reach the designed elevation, and thena full-length main steel beam, an inner ring steel beam, inner side auxiliary steel beams and outer side auxiliary steel beams are sequentially mounted. The mounting method is high in mounting efficiency and low in cost.
本发明公开了一种大跨度环状压力环单层网格钢屋盖的安装方法，在若干钢柱上安装大跨度环状压力环单层网格钢屋盖，包括以下步骤：先在钢柱上安装外环钢梁，然后根据压力环安装位置安装所述支撑承台，包括至少三个支撑单元，所有支撑单元位于压力环下方且沿压力环圆周均匀分布，相邻两支撑单元之间采用连接杆连接；支撑单元包括底座、以及设置在底座上的支撑架和设置在支撑架顶端的顶部承台，支撑架由若干标准节段上下设置组成；然后在支撑承台上的每个顶部承台上放置千斤顶，再将压力环放置在千斤顶上，调节千斤顶的工作高度以使压力环达到设计标高，然后再依次安装通长主钢梁、内环钢梁、内侧次钢梁和外侧次钢梁。该安装方法安装效率高、成本低。
