設置したスペーサで支持している。(Prior art) Conventionally, in the installation work of balconies, etc. of concrete buildings, the installation of step formwork to provide steps for waterproofing has been done by using step formwork using square batten material as the formwork material. Cantilever support is provided at the tip of a crosspiece whose base is fixed to the formwork board at the outer end of the cantilever slab. Additionally, the reinforcing bars of the slab are supported by spacers installed on the formwork.
（発明が解決しようとする問題点）
上記桟木による支持方法によると、段差型枠を長い桟木

分な対応ができず、段差レベルの低下が起き易い状態に
ある。(Problems to be Solved by the Invention) According to the support method using crosspieces, the step formwork is supported cantilevered by long crosspieces, so the formwork lacks vertical stability. Since the fixed end of the crosspiece is based on the slab form board at the outer end of the cantilevered slab, which has relatively low strength, it cannot adequately respond to the concrete lateral pressure acting on the step form, resulting in a decrease in the step level. is likely to occur.
更に上記桟木が、スラブ型枠上に架橋した状態となるた

設作業等の障害となっていた。捷だスペーサ全設置する
作業が省略でき扛ば、施工の省力化となる。Furthermore, the crosspieces are in a state of being bridged over the slab formwork, which obstructs slab formwork work, slab reinforcement work, concrete pouring work, and the like. If the work of installing all the spacers can be omitted, construction labor will be saved.
