(Prior Art) When attaching a plate-shaped heat insulating material to a ceiling, wall, floor, etc. that is in contact with outside air in a house or the like, it is desirable that the plate-like heat insulating material is brought into contact with the ceiling, wall, floor, etc. without any gaps. In particular, at the connection between the floor and the wall where outside air easily flows in, the wall material inserted into the wall is always in contact with the foundation, and the connection between the wall and the girder that fixes the joists on the floor. In the same way, the heat insulating material is in close contact with the body insert.

(Problem that the invention aims to solve) When the insulation material is installed as described above, the insulation effect improves, but the space under the floor and the space inside the wall of the downstairs are blocked by the foundation and the insulation material, and Since the space inside the wall on the lower floor and the space inside the wall on the upper floor are separated by the shell and insulation material, cold air from the bottom of the floor does not flow into the wall, worsening ventilation on the wall and causing condensation inside. There is a problem that corrosion of the wood is likely to occur.

Conventional means for solving these problems have complicated structures and are expensive.

(Means for Solving the Problems) The present invention was made in order to solve the problems of the prior art described above. a horizontal piece that can be fitted into a plurality of recesses formed with appropriate gaps at the abutting part of the horizontal piece, a vertical piece that is continuous from one end of this horizontal piece, and side pieces that are provided at right angles from both sides of the horizontal piece. and vertical pieces provided perpendicularly from both sides of the vertical piece.By fitting the horizontal piece into the recess, the tips of the side pieces can be placed on the top surface of the base or the upper or lower surface of the barrel. By making the ends of the vertical pieces abut against the base or the inner surface of the sill, there is a space between the inner and outer wall boards below the base, between the upper and lower parts of the sill, and between the inside surface of the sill. A ventilation path is formed between the two.
