能率的であつた。(Prior art and its problems) In the construction of conventional concrete buildings, when assembling formwork for girders and slabs, first, the part shown by the dotted line in Figure 3 is opened, and then the formwork for the girder is opened.
Attach the PC cable support hardware 1, or install the sheath 2.
The work of installing the formwork is done from the side using this opening, and the framework of this opening is later constructed, which results in the work of assembling the formwork being divided into two steps, which is inefficient and Ta.

貫通してシース止め筋を設けた点にある。(Purpose of the invention and its features) The present invention can be installed by being inserted into the formwork of the girder from above, so that the assembly work of the formwork of the girder and slab can be done in one time, and the sheath can be installed from above. The purpose of this project is to provide a PC cable support hardware for a girder that can be installed from above, and its structural features include: A large protruding edge is provided to be fixed to the slab formwork, and a small protruding edge for forming a sheath accommodating portion is protruded inward from the midsection and lower part of both side walls. The point is that a sheath stopper is provided passing through the tip of the edge and the bottom wall of the main body.

小突起の突設位置を変化させて所定位置にシース
収容部があるようにする。 The PC cable support hardware for girders of the present invention is installed at intervals in the length direction of the girder formwork and holds the sheath in a predetermined position, but the sheath is placed vertically in the longitudinal direction. Since the sheath accommodating portion is located at a predetermined position, the height of the side wall and the protruding position of the intermediate small protrusion are changed according to the change.

（実施例）以下、図面（第１図と第２図）に基いて本考案
を具体的に説明する。(Example) Hereinafter, the present invention will be specifically explained based on the drawings (FIGS. 1 and 2).

外方に大突縁５，５′が突設されている。この大
突縁５，５′は第２図に示すようにスラブ型枠６
に固定され、大梁型枠７内に本体３を図示の状態
で保持するのに役立つ。 Main body 3 of the PC cable support hardware for girders of the present invention
has a U-shaped cross section, and has large projecting edges 5, 5' projecting outward from the upper ends of its side walls 4, 4'. These large projecting edges 5, 5' are connected to the slab formwork 6 as shown in Fig. 2.
, which serves to hold the body 3 in the state shown within the girder formwork 7.

側壁４，４′の中腹部と下方部には内方に小突
縁８，８′が突設されており、中腹部においては
上下２段の小突縁により、下方部においては小突
