我在长期施工中发现,现浇钢筋混凝土楼梯的传统支模方法不仅浪费材料,而且模板使用次数少。针对这种情况,我试制了套管三角模具,通过工程使用,取得了良好的效果。现将套管三角模具的制作和 In my long-term construction work, I discovered that the conventional formwork method of cast-in-place reinforced concrete staircases not only wastes materials, but also uses less template. In response to this situation, I tried the casing triangle mold and achieved good results through the use of engineering. The casing triangle mold is now produced and
