従来、鉄骨鉄筋コンクリート構造(SRC造)又は鉄筋コンクリート構造(RC造)の躯体工事において壁を構築する場合、例えば、建て方ヤードに仮設足場を設置し、この仮設足場を利用して、壁の構築箇所に壁鉄筋を組み立てて、この壁鉄筋の外側に壁鉄筋を内外から挟むように型枠を建て込み、この型枠の内側にコンクリートを打設することにより壁を構築し、このような作業を各階毎に繰り返し行うことにより、躯体の各階の壁を構築している。   Conventionally, when constructing a wall in a steel reinforced concrete structure (SRC structure) or reinforced concrete structure (RC structure) frame construction, for example, a temporary scaffolding is installed in the building yard, and this temporary scaffolding is used to construct a wall construction location. Assemble the wall rebars, lay the formwork outside the wall rebars so that the wall rebars are sandwiched from inside and outside, and construct the wall by placing concrete inside the formwork, and perform such work By repeating each floor, the walls of each floor of the building are constructed.
ところで、上記のような方法によって躯体の壁を構築する場合、仮設足場を各階毎に設置し、撤去することを繰り返し行う必要があるため、その作業に時間と手間がかかり、全体としての工期が長くなってしまう。   By the way, when building the wall of the frame by the method as described above, it is necessary to repeatedly install and remove the temporary scaffolding for each floor, so it takes time and labor for the work, and the construction period as a whole It will be long.
また、下階の柱、壁、床を構築した後に、足場、型枠等の部材を吊り上げて下階から上階へ移動させる必要があり、その作業に手間がかかる。さらに、大型パネル化した型枠を用いる場合には、小さいユニットに分割して吊り上げなければならず、その作業に手間がかかる。   In addition, after building the pillars, walls, and floors on the lower floor, it is necessary to lift members such as scaffolding and formwork and move them from the lower floor to the upper floor, which is troublesome. Furthermore, when using a large panel formwork, it must be divided into small units and lifted, which takes time.

Furthermore, since the upper end portion of the first fixing member is connected to the steel frame of the frame via the second connection member, it is possible to prevent the first formwork from being deformed inward by the concrete placing pressure. Therefore, each floor of the frame can be constructed with high accuracy.
さらに、型枠ユニットの第1固定部材及び第2固定部材を躯体の構築箇所を挟んで対向配置したときに、第1固定部材及び第2固定部材が躯体の各階の全高に対応し、第1型枠及び第2型枠が躯体の各階の半分の高さに対応することになるので、躯体の各階を下半分と上半分の2層に分けて構築することができる。従って、階高の異なる各種の躯体の構築に対応することが可能となる。   Furthermore, when the first fixing member and the second fixing member of the formwork unit are arranged to face each other across the building construction position, the first fixing member and the second fixing member correspond to the total height of each floor of the casing, Since the formwork and the second formwork correspond to half the height of each floor of the housing, each floor of the housing can be constructed by dividing it into two layers, a lower half and an upper half. Therefore, it is possible to cope with the construction of various types of frames having different floor heights.
