Also, formwork construction is generally not very accurate. Precasting can improve the accuracy and shorten the construction period, but the transport cost is high because the precast plate is heavy and the loading efficiency is low. When a steel structure is adopted as the structure type, the construction period can be shortened as compared with the RC (or SRC) structure, but the processing becomes complicated. In particular, in the case of a building with a door border, such as an apartment house, if it is made of a steel frame and has a brace structure, the processing becomes complicated, and the thickness of the door border wall requires the thickness of the sound insulation material in addition to the brace arrangement space Become thick.

壁用型枠の設置を一層精度良く行える。The system formwork of the present invention is a system formwork for forming one side of a reinforced concrete wall which is used to face another wall formwork, and comprises a plurality of standardized sheets arranged side by side. It is provided with a wall form, and a plurality of horizontal and vertical ends supporting the wall form. These wall forms, the horizontal and vertical ends can be divided and assembled mutually. I do. Some of the lateral ends are joined at both ends to a steel column and also serve as a joint material when the steel column is erected, and the wall form supports the load of a half precast slab of an upper floor. Is possible. As the other wall form, any structure such as a general wooden form can be used. For example, the wall form of the system form is fixed to the wall form by a separator. In this way, by systematizing the wall formwork and by itself having the function of a joining material when constructing a steel frame, the number of members can be reduced and work can be saved. In addition, since it is supported by a steel column that has been erected in advance, the arrangement accuracy of the wall form is improved, and the accuracy of the reinforced concrete wall to be constructed is improved. By arranging the rebar for a wall with the system formwork thus accurately installed as a guide, the covering accuracy of the rebar is improved. Since the wall formwork can support the half precast slab of the upper floor, the construction of the upper floor can be performed easily. This system formwork needs to be provided on only one side, and the cost can be reduced as compared with the case where both sides are used as the system formwork. Also, since this system formwork can be disassembled, it can be moved to the upper floor of the same building and used. In this system formwork, a truss may be used as the horizontal end and the vertical end which also serve as the joint material. Only a part of the truss may be used as the vertical end. In this way, by using the truss as the horizontal end and the vertical end, a lightweight and firm end can be obtained, and the wall formwork can be installed more accurately.
