簡単な作業なわりには能率が悪い欠点があつた。 Conventionally, connecting fittings for attaching hollow building materials to steel frames were made by inserting a square nut into the hollow part of the hollow building material, guiding the square nut to the hole for attaching the connecting fitting by hand, and aligning the square nut with the mounting hole. Sometimes they were fixed together with bolts, but it took time to move the square nuts inside the cavity and align them with the bolt holes.
Although it was a simple task, it had the disadvantage of poor efficiency.

圧部１５ａを形成している。(Example) In Fig. 2, reference numeral 10 denotes a jig main body formed in a plate shape, with a through hole 11 provided in the center, and a pin 12 penetrating vertically within the through hole 11 so as to be slidable. ing. A portion of the pin 12 that protrudes downward from the jig body 10 is formed in a flange portion, and this portion is housed in a cylinder 13 provided on the lower surface of the jig body 10, and the bottom wall of the cylinder 13 and the pin 12 The pin 12 is always projected upward by a spring 14 installed between the pin 12 and the pin 12. Note that since the pin 12 is inserted into the screw hole of the square nut when the square nut is placed on the jig body 10, the length protruding from the jig body 10 is formed to be slightly longer than the thickness of the square nut. has been done. Reference numeral 15 denotes a spring seat provided on the upper surface of the jig main body 10, one end of which extends from the jig main body 10, and its tip is bent downward toward the main body, and the tip becomes parallel to the jig main body 10. The pressing portion 15a is formed by bending in this direction.

前進を妨げられる（第４図）。 3 and 4, in order to attach the connecting fitting 2 to the hollow building material 1 using this jig, first,
Fit the pin 12 of the jig main body 10 into the screw hole of the square nut 20, place the square nut 20 on the top surface of the jig main body 10, and place the main body in the hollow part 1a of the hollow building material 1 with the spring seat 15 in front. Insert inside. The jig main body 10 is moved a desired distance by a push rod 17, and a mounting hole 1 for a connecting fitting is drilled in the wall surface of the hollow building material 1.
When reaching point b, the pin 12, which had been lowered against the spring 14 on the upper wall surface of the cavity 1a, moves into the mounting hole 1.
When b and the pin 12 match, the pin 12 is pushed into the mounting hole 1b by the spring 14, and the jig main body 10 is prevented from moving forward (FIG. 4).

前記治具本体１０はバネ座１５の弾力によつて
空洞部１ａの上方に付勢されているので、治具本
体１０を空洞部１ａ内に放置しても本体は一定の
姿勢を保つており、従つてピン１２と取付孔１ｂ
の係合状態を維持することができる。 Since the jig main body 10 is urged upward in the cavity 1a by the elasticity of the spring seat 15, the main body maintains a constant posture even if the jig main body 10 is left in the cavity 1a. , therefore the pin 12 and the mounting hole 1b
The engaged state can be maintained.

次いで連結金具２を前記取付孔１ｂに一致させ

る。 Next, the connecting fitting 2 is aligned with the mounting hole 1b, and the fixing bolt 21 is inserted into the bolt hole of the connecting fitting.
Tighten the square nut 20 inside the cavity. If the length of the square nut 20 is approximately the same as the width of the cavity, the square nut can be fixed without rotating when the fixing bolt 21 is tightened. Further, when the fixing bolt 21 is tightened to the square nut 20, it is pushed down while pushing the pin 12 into the cylinder 13.

ボルトの締付作業終了後は押込棒１７を引抜
き、中空建材１から治具本体１０を除去すれば連
結金具２の取付作業は終了する。 After the bolt tightening work is completed, the push rod 17 is pulled out and the jig main body 10 is removed from the hollow building material 1, thereby completing the installation work of the connecting fitting 2.

このようにして連結金具２が中空建材１に取付
けられた後は、第１図に示すように連結金具２を
鉄骨に結合して中空建材を建造物の外壁あるいは
間仕切壁とする。 After the connecting fittings 2 are attached to the hollow building material 1 in this manner, the connecting fittings 2 are connected to the steel frame as shown in FIG. 1, and the hollow building material becomes an outer wall or a partition wall of a building.

実施例では、前記治具本体１０を上方に付勢す
