Refuge storey cantilever formwork support construction method and cantilever formwork support of refuge storey cantilever formwork support construction method
The invention provides a construction method of a refuge floor cantilever formwork support. The construction method comprises the following steps that (1) proper model selection is conducted on main beams and coupling beams according to working conditions; (2) an anchor ring is pre-buried in the construction of a lower floor of the refuge floor, and a through-wall hole box and a steel wire rope through-wall hole are pre-buried in a wall column; (3) building a refuge floor cantilever formwork support; (4) an outer side protection single-row outer scaffold is erected; and (5) the steel pipes at the fixed ends of the main beams are jacked back, and construction of the refuge floor cantilever formwork support is completed. Meanwhile, the invention discloses a refuge floor overhanging formwork support which comprises a main beam, a connecting beam, a steel pipe and a single-row external scaffold, one end of the main beam is fixed to a refuge floor lower floor, the other end of the main beam penetrates through a current-layer wall column to be overhung outside the current-layer wall column, the connecting beam is fixed to the main beam at intervals, and a back-jacking steel pipe is arranged at the end, fixed to the refuge floor lower floor, of the main beam. The single-row external scaffolds are arranged on the main beams and the connecting beams. The construction method has the advantages of convenience and low cost, and the cantilever formwork support has the advantages of high safety, neatness, attractiveness and good integrity.
本发明提供一种避难层悬挑支模架施工方法，包括以下步骤：步骤1）主梁和联梁根据工况进行合适选型；步骤2）于避难层下层楼板施工中预埋锚环，墙柱内预埋穿墙洞口盒子和钢丝绳穿墙洞口；步骤3）避难层悬挑支模架搭设；步骤4）搭设外侧防护单排外脚手架；步骤5）主梁固定端钢管回顶，完成避难层悬挑支模架施工。同时公开了一种避难层悬挑支模架，包括主梁、联梁、钢管和单排外脚手架，主梁一端固定于避难层下层楼板，主梁另一端穿过当层墙柱悬挑于当层墙柱外，联梁间隔固定于于主梁，主梁固定于避难层下层楼板端上设回顶钢管，单排外脚手架设置于主梁和联梁。本发明施工方法具有便捷，成本低的优点，悬挑支模架具有安全性高，整洁美观，整体性好的优点。
