であった。2. Description of the Related Art Conventionally, a steel sheet concrete structure (SC structure) is a structural type having superior proof strength and deformability by integrating a surface steel sheet and concrete as compared with a conventional reinforced concrete structure. In addition, since the SC structure can be used as a structural material that doubles as a temporary formwork when placing concrete, the SC steel plate that becomes the surface steel plate eliminates the need for reinforcing bars and stencil, which are required in a reinforced concrete structure. It was possible to reduce the time required and the construction period could be shortened.

Then, the SC steel plate units were joined together by in-situ welding. Further, the SC steel plates were directly assembled at the construction site, and the SC steel plates were welded to each other for attachment. In any case, after being assembled and joined by welding means, the inside of which is filled with concrete and the concrete is hardened, whereby a structural type that exhibits the required strength as a composite integrated structure consisting of surface steel plate and concrete Met.

A joining means such as bolt joining of the C steel plate unit or the SC steel plate is also conceivable, but it is not realistic in the following points and there is a problem in practical use. (1) It is necessary to tighten a huge amount of bolts, which increases man-hours at the construction site. (2) When the wall thickness is thin, it is difficult to work from the inside and bolts cannot be tightened. (3) The heads of the bolts are exposed to the outside of the surface steel plate, which is noticeable in appearance and reduces the effective volume of the space to be constructed.

ため、以下の解決すべき課題を有していた。As described above, the steel plate concrete structure (SC structure) generally has an extremely excellent performance in terms of structure, but in terms of construction, SC steel plate units are used together at the construction site. It is necessary to weld and join, and therefore, there are the following problems to be solved.

(1) In order to join SC steel plate units to each other, it is necessary to perform an enormous amount (welding length) of on-site welding (Y portion in FIGS. 21 and 22), which increases man-hours at the construction site. . (2) All the joints of the surface steel plates of the enormous units, which are enormous, must be welded on site, and the workability is poor. (3) In the field welding, it is impossible to secure a good construction environment similar to factory welding, which makes it difficult to secure reliability.
Welding control over the entire process to confirm the welding status is essential. In addition, man-hours for welding management are added.

The accuracy of the welded joint interval, misalignment, etc. is determined by the installation accuracy of the unit, so it is difficult to ensure accuracy. (5) Since the units are welded to each other, it is necessary to absorb the error due to the installation accuracy of each unit by on-site welding in construction. However, the on-site welding has a limit to the error absorption width. Particularly, when the surface steel sheets around the entire unit are joined by in-situ welding, the absorption becomes difficult. (6) The reliability and construction accuracy of on-site welding depend on the construction environment, and the workable days are limited depending on the climate, or appropriate curing is required.

(3) Since the welding required to attach the SC steel plate units to each other can be performed by factory welding, reliability is improved. In addition, no special welding control is required to check the on-site welding status, and the number of man-hours at the construction site for welding control is greatly reduced.
【００４３】（４）ＳＣ鋼板ユニット相互の間隔、目違
い等の据え付け精度による誤差及び部材の製作上の誤差
等の誤差吸収が容易となり施工性が飛躍的に向上した。
（５）気候によって施工可能日が限定されず、特別の養
生が必要でなくなった。(4) It is easy to absorb the error due to the installation accuracy such as the distance between the SC steel plate units and the misalignment and the error in the manufacturing of the member, and the workability is improved dramatically. (5) Due to the climate, construction days are not limited, and no special curing is required.
