取り外して何回でも転用することができる。The fastening jig of the present invention is installed using the beam main reinforcement on the opposite side of the concrete casting side of the net formwork installed at the new and old joints of beam concrete. It prevents the formwork from moving and leaking around the rebar, and can be removed and reused any number of times after the cast concrete has hardened.
（図面による説明） 図面において、１は本考案の一実施例である留め金具
を示している。(Description by Drawing) In the drawings, reference numeral 1 denotes a fastener which is an embodiment of the present invention.
留め金具１は、１対の半メガネ状金具2,2と締付けボ
ルト３とから成り、各半メガネ状金具２の両端部には梁
主筋を掴むための半円弧状部4,4′が形成され、また、
中間部５には締付けボルト３を通すためのボルト孔６が
穿設されている（第１図参照）。The clasp 1 is composed of a pair of semi-spectacle-shaped metal fittings 2 and 2 and a tightening bolt 3. Semi-circular arc-shaped parts 4, 4 'for gripping a beam main bar are formed at both ends of each semi-glass-shaped metal fitting 2. And also
A bolt hole 6 for passing the tightening bolt 3 is formed in the intermediate portion 5 (see FIG. 1).
留め金具１を所定位置に取り付けるときは、半円弧状
部4,4と４′,4′でそれぞれ隣接の梁主筋の全周を囲
み、ボルト孔６に通した締付けボルト３で半メガネ状金
具2,2を一体的に接合すればよい。When the fastener 1 is to be mounted at a predetermined position, the semicircular portions 4, 4 and 4 ', 4' respectively surround the entire circumference of the adjacent beam main reinforcement, and the semi-eyeglass-like metal fitting is fastened by the tightening bolt 3 passed through the bolt hole 6. What is necessary is just to join 2 and 2 integrally.
留め金具１の一使用態様を示す第２図において、７は

段上ば主筋9,9同士であってもよい。In FIG. 2 showing one use mode of the fastener 1, 7 is a semi-precast concrete beam (hereinafter, simply referred to as a beam), 8 is a main reinforcing bar in the upper stage of the beam 7, 9 is a main reinforcing bar in the upper stage of the same, and 10 is a net type. The frame 11 is a slab stop form, and the net form 10 is a concrete joint at the top half of the beam 7 formed by cast-in-place concrete 12.
The clasp 1 is installed before the casting of the concrete 12 and is attached as described above in contact with the surface of the net form 10 opposite to the side where the concrete 12 is cast. The main bar may be a combination of the main bar 8 at the upper stage and the main bar 9 at the lower stage, or may be the main bars 8, 8 at the upper stage or the main bars 9, 9 at the upper stage.
（考案の効果） 本考案の留め治具は、以上のようなものであるから、

きる。(Effects of the invention) Since the fastening jig of the invention is as described above,
It can be easily installed using the beam main reinforcement, and can reliably prevent the movement of the net form due to the lateral pressure of the poured concrete. Leakage can be effectively prevented.
