For example, a load-bearing wall made of a steel plate concrete structure has steel plates 1 and 1', which also serve as concrete formwork, arranged on both sides of the wall as shown in FIG.
1' are connected by vertical or horizontal steel plate webs 2 to form a steel plate block 3, and the inside is filled with concrete 4. Further, the floor is constructed by placing reinforcing bars 7 on a steel plate 5 with a shear connector 6 such as a stud dowel projecting thereon, and pouring concrete 4 to an appropriate thickness. These walls and floors have improved structural safety due to the combined effect of steel and concrete, and the composition of the structural system greatly contributes to the rationalization of construction, making them ideal for building large structures such as nuclear power plants and silos. Are suitable.

補強筋などを配筋するものである。 By the way, if we take the example of row buildings at a nuclear power plant, most of them have conventionally been constructed using RC (reinforced concrete) structures.For example, when it comes to load-bearing walls and floors made of RC, pipe penetration points are constructed after the formwork has been constructed. A piping sleeve is installed within the formwork, and opening reinforcing bars are placed around it.

It is the same as Figure 7. The steel plate blocks are manufactured in a factory or the like, transported to the site, assembled together as described below, and filled with concrete to form a load-bearing wall.

もので、該ウエブ２を介して鋼板１，１′に沿つ
て予め設けられることになる。 The steel plate web 2 has a role as a reinforcing rib in the steel plate block 3, and in the present invention, a steel pipe 8 for piping is arranged in the center of the steel plate web 2 of the steel plate block 3. The steel pipe 8 is made by dividing the steel plate web 2 into two parts and welding them into one piece, and is provided in advance along the steel plates 1 and 1' via the web 2.
さらに、必要がある場合には、鋼板１，１′を

鋼板１０を取付ける。この鋼管９は、前記長尺な
鋼管８と直交して連通している。 Furthermore, if necessary, a short piping steel pipe 9 is installed so as to pass orthogonally through the steel plates 1 and 1', and a reinforcing steel plate 10 is installed around the opening of the steel pipe 9 for correction. This steel pipe 9 communicates orthogonally with the long steel pipe 8.

At the site, the upper steel plate block 3 is lifted by a crane or the like, assembled on the lower block 3, joined by welding or the like, and concrete is poured inside to obtain a load-bearing wall of the steel plate concrete structure.

As shown in the figure, reinforcing ribs 11 are provided vertically or horizontally by welding or the like so as to stand up vertically from the steel plate 5.
A steel pipe 12 for piping was attached by welding along the reinforcing rib 11. In the figure, 13 is steel pipe 1
The piping outlet connected to 2 is shown.

となる。 In addition, in the above embodiment, the steel pipes 8, 9,
12 are all shown as cylinders, but rectangular tubes may also be used as shown in FIGS. 5 and 6. Even a circular pipe functions as a shear connector by integrating with the web 2 and ribs 11, and connects the concrete 4 and the steel plate 1,
It helps to improve unity with 1' or 5, but
If this is a rectangular tube, the effect will be even greater.

As described above, the method of constructing a steel plate concrete structure of the present invention not only provides a high-strength structure due to the combined effect of steel plates and concrete, but also allows for all piping setup to be done on-site at the factory. This improves the construction process, eliminates the need for complicated formwork, shortens the process, and reduces costs. Furthermore, the effect of reinforcement on strength is ensured, and quality can also be improved.
