Description

  The present invention relates to a heat insulating panel used for forming an outer wall of a building or a house.

  Conventionally, a heat insulating panel in which a core material is filled between two metal shells has been proposed. This heat insulation panel is juxtaposed in the vertical and horizontal directions and used as a wall such as an outer wall of a building.

  In such a heat-insulating panel, when the temperature rises due to being exposed to a flame in the event of a fire, the metal outer shell and the core material may come off and the metal outer shell may fall off. For this reason, two metal shells constituting the heat insulation panel are connected by a connecting member to prevent the metal shell from coming off the core material and dropping off (see, for example, Patent Document 1).

  In FIG. 8, an example of the structure of the heat insulation panel provided with the conventional connection member is shown. The heat insulation panel A is formed by including two metal skins (first metal skin 1 and second metal skin 2), a core material 3, a refractory material 5, a connecting member 6, and the like. The connecting member 6 is disposed between the inner side surface 5Z of the refractory material 5 provided at the end of the heat insulating panel A and the outer side surface 3Y of the core material 3 adjacent to the refractory material 5. And the 1st connection fixing piece 15 provided in the 1st metal shell 1 and the connection member 6 are couple | bonded by fixing tools 30, such as a screw | thread. Moreover, the 2nd connection fixing piece 25 provided in the 2nd metal shell 2 and the connection member 6 are couple | bonded by fixing tools 30, such as a screw. The fixture 30 penetrates the refractory material 5 from the outside of the heat insulation panel A and is driven into the connecting member 6. Thus, the first metal skin 1 and the second metal skin 2 are connected by the connecting member 6. In this heat insulation panel A, the refractory material 5 is interposed between the first connection fixing piece 15 and the second connection fixing piece 25 and the connection member 6, and the first connection fixing piece 15, the second connection fixing piece 25 and the connection member. 6 to prevent contact. Thereby, the heat conduction (what is called a heat bridge) which arises when the 1st connection fixing piece 15 and the 2nd connection fixing piece 25 and the connection member 6 contact is made small, and the heat insulation of the heat insulation panel A is ensured.

  However, this connecting member is provided between the refractory material and the core material constituting the heat insulating panel, that is, inside the heat insulating panel. Therefore, there is a problem that it is difficult to understand the installation position of the connecting member from the outside of the heat insulating panel, and it is difficult to drive the fixture toward the connecting member.
