Description

  The present invention relates to a heat insulating panel connection structure that can be used when forming a wall such as an outer wall.

  Conventionally, sandwich panels have been used as heat insulation panels such as wall panels (see, for example, Patent Document 1). FIG. 7A shows an example of the heat insulation panel A ′. The heat insulating panel A ′ is formed by sandwiching a heat insulating material 3 such as rock wool between two metal surface plates 1 and a back plate 2. Moreover, the fitting convex part 5 is formed in the upper end part of heat insulation panel A ', and the fitting recessed part 4 is formed in the lower end part of heat insulation panel A'. In this heat insulating panel A ′, the lower end portions of the front surface plate 1 and the back surface plate 2 are bent upward to bend upward and downward to form bent portions 6 and 7 having a substantially U-shaped cross section. A space between the portions 6 and 7 is formed as the fitting recess 4. In addition, a head receiving recess 15 is provided on the surface side of the fitting protrusion 5.

  Further, a reinforcing tool 10 is provided on the heat insulation panel A ′ for reinforcement. That is, as shown in FIG. 7B, one side piece of the metal reinforcing tool 10 having a U-shaped cross section or a U-shaped cross section is inserted as an insertion piece 26 inside the bent portion 6 of the surface plate 1. By inserting the other side piece of the reinforcing tool 10 into the bent portion 7 of the back plate 2 as an insertion piece 26, the reinforcing tool 10 is arranged on the fitting recess 4 side of the heat insulating panel A ′. The fitting recess 4 can be reinforced by the reinforcing tool 10 formed by the pair of insertion pieces 26 and 26 and the connecting piece 27 connecting them.

  In constructing the heat insulation panel A ′, the heat insulation panel A ′ is disposed on the surface of the base material 25 such as the trunk edge, and a fixing tool 24 such as a nail or a screw is driven from the bottom surface of the head housing recess 15. Then, the base material 25 is penetrated. After attaching the heat insulation panel A ′ in this way, another heat insulation panel A ′ is brought closer from the upper side thereof, and the fitting recess 4 of the upper heat insulation panel A ′ is moved to the lower heat insulation panel A as shown in FIG. It fits in the fitting convex part 5 of '. In this way, a plurality of heat insulation panels A ′ can be arranged side by side in the vertical and horizontal directions while connecting the heat insulation panels A ′ and A ′ adjacent in the vertical direction to form a wall.

  However, when a negative pressure is applied to the heat insulating panel A ′ provided with the reinforcing tool 10, a force acts in a direction in which the heat insulating panel A ′ is peeled off from the base material 25. Therefore, as shown in FIG. When the bending occurs and the bending becomes very large, the bent portion 7 of the back plate 2 gets over the fitting convex portion 5 and the fitting concave portion 4 and the fitting convex portion 5 are disengaged. There was a risk that the insulation panels A ′ and A ′ would be disconnected.

In addition, heat transfer (so-called heat bridge) occurs between the front and back of the heat insulation panel A ′ through the reinforcing tool 10, and there is a fear that the heat insulating performance may be reduced as compared with the case where the reinforcing tool 10 is not provided. .

It becomes difficult to peel off from the heat insulating material 3, and damage to the heat insulating panel A due to negative pressure can be prevented.

  In the present invention, the surface plates of the adjacent heat insulation panels are connected by the engagement of the engagement pieces and the engagement pieces without using a reinforcing tool for connecting the front surface plate and the back surface plate as in the conventional example. As a result, even if a negative pressure is applied to the heat insulation panel and the bending occurs, it is difficult for the negative pressure force to be applied to the back plate, so that the fitting recess can be prevented from being damaged. The fitting recesses and the fitting projections 5 can be prevented from being completely disengaged, and the adjacent heat insulation panels can be prevented from being disconnected. Moreover, since the surface plates of the adjacent heat insulating panels are connected by the engagement of the engaging pieces and the engaged pieces, there is no need to separately prepare other members such as a conventional reinforcing tool. It is possible to prevent heat from moving between the front and back through the reinforcing tool, and to prevent a decrease in heat insulation performance.

The reinforcing piece portion 33 protrudes from the upper end portion of the concave step portion 32 toward the inner surface side (the surface side facing the heat insulating material 3 side), and the tip thereof is bent downward. The bent portion 7 is formed by bending inwardly (inner surface side) into a U-shaped section that is shorter in the vertical direction than the bent portion 6 of the surface plate 1, and a reinforcing piece 35 projects from the tip. It is installed.
