The plate-like heat insulating material 6 such as glass wool board or rock wool board is fixed, and is made of metal plate or synthetic resin.

  This heat insulating material fixture 10 is, for example, a plate-shaped vertical piece 11 that is in close contact with the side surface of the joist 5 that is a shaft set, and is inserted in the middle of the plate-shaped heat insulating material 6 in the thickness direction, extending to the lower end of the vertical piece 11 A plate-like insertion piece 12 and a plate-like upper piece 13 that extends from the upper end of the vertical piece 11 and is placed and supported on the upper surface of the joist 5 that is a shaft set, for example, bending a metal plate material Thus, it is configured in a substantially Z shape.

That is, in this heat insulating material fixture 10, the lower surface of the plate-shaped heat insulating material 6 is not supported, but the insertion piece 2 is inserted and supported on the side end surface in the thickness direction of the plate-shaped heat insulating material 6.
For this reason, the tip of the insertion piece 12 of the heat insulating material fixture 10 is formed to be sharpened in an isosceles triangular shape protruding forward, so that it can be easily inserted into the plate heat insulating material 6. In addition, the shape which sharpens the front-end | tip of the insertion piece 12 is not restricted to an isosceles triangle shape, Other shapes, such as cutting off diagonally, may be sufficient.
And this heat insulating material fixture 10 is made into the substantially Z shape, for example, the angle which the vertical piece 11 and the insertion piece 12 make, and the angle which the vertical piece 11 and the upper piece 13 make are right angle, respectively.

  Further, the insertion piece 12 is formed with a projecting piece 14 formed by forming two triangular cuts and bent downward from the bottom, making it easy to insert and difficult to remove as an acute angle with respect to the insertion direction.

In the heat insulating material fixture 10, the upper piece 13 supported by the shaft set 5 is configured such that the vertical piece 11 extends only at one end of the upper piece 13.
In this heat insulating material fixing tool 10, the insertion piece 12 is inserted into the plate-shaped heat insulating material 6, so that the joist 5 or the like that is a shaft set in advance as a substantially U-shape like the conventional heat insulating support metal fittings and receiving tools, etc. The heat insulating material fixture 10 is inserted into the plate heat insulating material 6 first, and then attached to the shaft assembly 5 for use.

  As shown in FIG. 2, the heat insulating material fixture 10 configured as described above first inserts the insertion piece 12 into the middle in the thickness direction of the side end surface of the plate-shaped heat insulating material 6 when attached to the shaft assembly 5.
