主筋３ａ，３ｂが収められている。 Here, the installation state of both PC formworks 5 and 6 will be explained. The PC formworks 5 and 6 are installed in correspondence with each other, and the joint 11 of the horizontal parts 5a and 6a is located on a straight line passing through the web 1a of the beam steel frame in this example. Further, the ribs 7 and 8 are opposed to each other as shown in FIG. And ribs 7... and 8...
was hung on the inner surface of the flange 1b on the lower side of the beam steel frame, and was installed horizontally passing through the web 1a.
The vertical portions 5a, 6a of the PC formwork are supported at both ends of a connecting rod 12, which is a means for connecting and fixing the PC formwork, so that the PC formworks 5, 6 are held on the beam steel frame 1. Therefore, the ribs 7 and 8 function as ribs for latching the PC formworks 5 and 6, and the lower surfaces of the ribs serve as surfaces to be latched to the upper surface of the lower flange 1b. As shown in FIG. 1, the space surrounded by the PC formworks 5 and 6 contains the beam steel frame 1, the main part of the stirrup, and the lower beam main reinforcements 3a and 3b.

との一体性が確保される。 To explain the construction of the beam, as shown in Figure 1, reinforcements 3 and 4 are placed on the beam steel frame 1 in advance, and PC forms 5 and 6 are attached, and the beam steel frame is erected on the column 1. At the same time as concrete pouring
Concrete is poured into the PC forms 5 and 6 and the beams are constructed. In this way, the PC formwork 5, 6, beam steel frame 1, lower beam main reinforcements 3a, 3b, and stirrup 4 are integrated with concrete to form a beam, and at the same time, the beam, indoor slab S, and cantilever slab Sa are integrated.
The integrity of the project is ensured.
勿論、先に梁鉄骨を架設しておいてから、後か
らPC型枠５，６を取り付け、コンクリートを打
設してもよい。 Of course, the beam steel frame may be erected first, then the PC forms 5 and 6 may be attached and concrete poured.
いずれの場合においても、一節の柱に３層分の

The angle members 14, 15 may be attached to the inner surfaces of the angle members by bolts 13, 13, etc., and other angle members 16, 16a, 17, 17a may be attached to the upper and lower ends of each angle member, respectively. Note that the angle members 14, 15 are replaced with the angle members 16, 16a, 1.
As a method of attaching 7, 17a, for example, bolts, welding, etc. are used. At the construction stage, it is a connecting and fixing means. The angle members 16 and 17 are fixed to the flange 1c of the beam steel frame 1 with bolts, and the angle members 16a and 17a are supported on the other flange 1b.
またPC型枠の形状も上例に限られず、第７図
