Cantilever steel platform penetrating through light well area and construction method of cantilever steel platform
The invention discloses an overhanging steel platform penetrating through a light well area and a construction method, the overhanging steel platform comprises a plurality of overhanging beams, the upper portion, penetrating through the light well area, of one end of each overhanging beam is an anchoring section, and the other end of each overhanging beam is an overhanging free section; coping profile steel is fixedly arranged above the area, penetrating through the light well, of the anchoring section, limiting profile steel is arranged on the inner wall of the well in an abutting mode, and the upper surface of the limiting profile steel is fixedly connected with the cantilever beam. The cantilever beam is anchored through a U-shaped ring bolt; inclined struts are arranged between the free sections of the cantilever beams and the lower layer. The problem that the anchoring section is difficult to fix when the overhanging I-shaped steel platform with large load passes through the light well is solved. A piece of horizontal limiting profile steel is installed in the hoistway, one side of the limiting profile steel abuts against the inner wall of the hoistway, the upper portion of the limiting profile steel is fixedly welded to the bottom of the cantilever I-shaped steel, and it is guaranteed that horizontal and vertical stress of the cantilever I-shaped steel is stable.
本发明公开了一种穿越采光井区域的悬挑钢平台及施工方法，包括若干悬挑梁，其中，悬挑梁的一端穿越采光井区域的上部为锚固段，另一端为悬挑自由段；锚固段穿越采光井区域的上方固定设置压顶型钢，井道内壁紧靠设置限位型钢，限位型钢的上表面与悬挑梁固定连接；悬挑梁通过U型环螺栓进行锚固；悬挑梁自由段与下层之间设置斜撑。解决了存在较大荷载的悬挑工字钢平台穿越采光井道时锚固段难以固定问题。在井道内安装一根水平限位型钢，限位型钢一侧顶靠在井道内壁，上部与悬挑工字钢底部焊接固定，确保了悬挑工字钢水平和竖向受力稳定。
