For example, as shown in FIG. 4, the rafter stopper 41 generally has a shape in which an L-shaped member 44 is attached to the bottom plate portion 43 a of the base member 43 of the pipe clamp 42, and the L-shaped member 44 is erected. The surface 44a is brought into contact with the side of the rafter of the wooden building, a fixing tool such as a nail or a screw is driven into the nail hole 45, and a pipe material such as a steel pipe used for the temporary scaffolding is supported and fixed by the pipe clamp 42. It is supposed to be possible.

  However, in such a conventional rafter clasp 41, the rafter of the wooden building and the L-shaped member 44 of the rafter clasp 41 are only supported and fixed on one side of the rafter, and the temporary scaffold However, it cannot be said that the steel pipe and other pipe members used in the construction are supported and fixed with sufficient strength, and there is room for improvement in improving the supporting and fixing strength.

  Therefore, for the purpose of improving the support and fixing strength of steel pipes and other pipes used for temporary scaffolds and wooden buildings, the support for fixing steel pipes and other pipes and wooden structures used for temporary scaffolds so far Various ingenuity and improvements have been attempted for metal fittings.

  For example, in order to support the pipe material such as the steel pipe used for the temporary scaffolding on the wooden building side, the pipe material such as the steel pipe used for the temporary scaffolding provided on the outer periphery of the wooden building is exposed to the wooden building. There has been proposed a supporting and fixing bracket that can be easily connected to and supported by a protruding corner of a wooden part (see Patent Document 1). As shown in FIG. 5, the support fixing metal fitting 51 described in Patent Document 1 includes a strip-shaped substrate 52, an L-shaped member 53, and a pipe clamp 54. A nail hole 55 is provided, and the L-shaped member 53 is provided with a second nail hole 56 in a protruding plate portion 53 a that protrudes from the belt-like substrate 52 at a right angle. In this support fixing bracket 51, one end portion of the belt-like substrate 52 having the first nail hole 55 and the L-shaped member 53 are provided at the protruding corner portion S of a suitable wooden portion such as a wooden pillar or a window frame in a wooden building. The second nail hole provided in the first nail hole 55 of the belt-like substrate 52 and the projecting plate part 53a of the L-shaped member 53 after the right-angled corner part s between the projecting plate part 53a and the projecting plate part 53a is fitted. A fixing tool 57 such as a nail or a screw is driven into 56 and fixed.

  For this reason, in the support fixing metal fitting 51 described in Patent Document 1, it is possible to support and fix on two orthogonally arranged surfaces, and a steel pipe used for a temporary scaffold provided on the outer periphery of a wooden building. It is said that a pipe material such as can be easily connected to and supported by a wooden building.

  In the support fixture 51 described in Patent Document 1, the pipe clamp 54 includes a long hole 58 provided in parallel with the length direction of the belt-like substrate 52, and a mounting plate portion 53 b of the L-shaped member 53. It is attached to the L-shaped member 53 so as to be movable and fixed by bolts and nuts 59 and 60 penetrating therethrough.

  For this reason, in the support fixing metal fitting 51 described in Patent Document 1, the pipe clamp 54 and the L-shaped member 53 can be slid together, depending on the width and thickness of the wooden part of the wooden building. The mounting position of the L-shaped member 53 can be adjusted.
