Tool type ultra-large-gradient inclined roof construction formwork and construction method

SUN RUIJIA / LI YONGSHENG / LI HONGMEI / LI CHENYANG

The invention discloses a tool type ultra-large-gradient inclined roof construction formwork and construction method. The construction formwork comprises an inner layer roof aluminum alloy formwork, an outer layer roof aluminum alloy formwork and a scaffold. The top of the scaffold is fixedly connected with a set of adjustable telescopic ejection rods. The adjustable telescopic ejection rods are supported to the bottom of the inner layer roof aluminum alloy formwork. The outer layer roof aluminum alloy formwork is arranged on the inner layer roof aluminum alloy formwork in parallel. The innerlayer roof aluminum alloy formwork and the outer layer roof aluminum alloy formwork are fixedly connected together through connection assemblies. By means of the double interlayer aluminum alloy formworks, the problems that large-gradient inclined roof concrete is large in liquidity and not likely to be formed are effectively solved, the quality problems such as honeycombs, pitted surfaces and exposed ribs are reduced, the problems that roof leakage is caused and a large amount of repair needs to be conducted in the later period are reduced, the construction progress is accelerated, and safe and efficient construction is achieved.

本发明公开了一种工具式超大坡度斜屋面施工模板及施工方法，该施工模板包括内层屋面铝合金模板、外层屋面铝合金模板以及脚手架，在脚手架的顶部固定连接有一组可调节伸缩顶杆，所述的可调节伸缩顶杆支撑在内层屋面铝合金模板的底部，在内层屋面铝合金模板上平行地设置有外层屋面铝合金模板，且内层屋面铝合金模板和外层屋面铝合金模板之间通过连接组件固定连接在一起。本发明的双夹层铝合金模板有效地解决了大坡度斜屋面混凝土流动性大、不易成型的难题，减少蜂窝、麻面、露筋等质量问题出现，减少了屋面渗漏以及后期进行大量修补的问题，加快施工进度，达到安全高效施工。
