2a is screwed.

[0006] Next, referring to FIG. 26, a heat insulating material 111 adjusted to the installation position is appropriately pressed against the separator 102, and a mounting hole for inserting the separator 102 into the heat insulating material 111 is marked. According to the marking, a mounting hole 111a is provided in the heat insulating material 112 on the spot. Mounting hole 11
The heat insulating material 111 on which 1a is formed is inserted into each of the separators 102. The female screw of the fastening member 105 is screwed into the male screw 102b of the separator 102 projecting from the mounting hole 111a, and the separator 102 and the fastening member 105 are fixed. At this time, the heat insulating material 111 is fastened and fixed in a state of being sandwiched between the flange 105b and the heat insulating material holding attachment 113.

There is no step. Thereby, as shown in FIG. 6, a highly accurate heat insulating concrete wall can be formed. In addition, since concrete does not easily flow between the adjacent heat insulating panels, the heat insulating property is further improved.

The mounting holes 7d formed in the front plate 7a of the form panel member 7 having high dimensional accuracy are formed at a predetermined interval. Therefore, when a plurality of form panel materials are combined, the mounting holes are regularly arranged. At the position facing each of the regularly arranged mounting holes, the mounting holes 11 are previously formed in the heat insulating composite panel material.
It is easy to process c and 11d. This allows
The work of aligning and processing the mounting holes at each site is omitted. As a result, work efficiency is greatly improved.

By the way, in the related invention , as described above, the fastening member is disclosed in Japanese Patent Application No. 08-152.
Although the fastening member described in 222 is used, a fastening member shown in FIG. 7 may be used in addition thereto.
