The present invention also relates to a joining structure of heat insulating panels in which fixing tools 11 passing through the ends of the heat insulating materials 5 of both heat insulating panels 6 are fixed to the mounting structure material 12.

The purpose of the present invention is to provide a connection structure for heat insulation panels that can firmly connect heat insulation panels to each other and that has excellent heat insulation properties at the joints of the heat insulation panels.

The present invention will be explained in detail below using examples.

The front metal plate 3 has a plurality of peaks 1 and valleys 2 as shown in Fig. 2.
It is bent over the entire length in the longitudinal direction and is made of galvanized steel plate or the like, and is shaped so that the peaks 1 are located at both ends.

A part of the peak 1 located at the left end of the front metal plate 3 is cut out, and the upper surface piece of this peak 1 is used as the joint piece 9, and the peak located at the left end of the front metal plate 3 is used as a joint piece 9. A part of the portion 1 is cut out and the upper surface piece of the peak portion 1 is used as a joint protrusion 10, and a bent piece 13 extends from the tip of the joint protrusion 10.

The back side metal plate 4 is made of a galvanized steel plate or the like with small corrugated irregularities or a flat surface as shown in FIG.

At the left end of the back metal plate 4, there is provided a lower overlapping piece 7 formed by folding the end of the back metal plate 4 upward and inward, and at the right end of the back metal plate 4, the back side An upper overlapping piece 8 is provided by folding the end of the metal plate 4 upward and inward.

A recessed step 14 is formed on the lower surface of the upper stacked piece 8.

A foamed polyurethane, foamed isocyanurate, foamed phenol, etc. is injected between the front side metal plate 3 and the back side metal plate 4, and is foamed and hardened, so that a heat insulating material 5 is enclosed between the two metal plates 3 and 4, as shown in Fig. 1. This forms a heat insulating panel 6.

At this time, a heat insulating material 5 is placed inside the lower stacked piece 7 and the upper stacked piece 8.
The insulation material 5 is filled so that the joint piece 9
The end of the heat insulating material 5 should also be applied to the lower surface of the housing.

The joining protrusion 10 is made to protrude outward from the heat insulating material 5,
A fitting recess 15 is formed inside the joint protrusion 10.

The end faces of both side ends of the heat insulating material 5 are each made into an inclined surface, and these two inclined surfaces are set in a substantially parallel relationship.

Therefore, the heat insulation panels 6 are used as roofing materials by laying a large number of them on the mounting structure material 12 such as a roof structure material, but the joining of the heat insulation panels 6 and the mounting structure material 12 is difficult.
The fixing is done as follows.

That is, as shown in FIG. 4, of the adjacent heat insulating panels 6.6 placed on the mounting structure material 12, the lower stacked piece 7 of one of the heat insulated panels 6 has a concave step on the upper stacked piece 8 of the other heat insulated panel 6. Part 1
4 and stack the upper stacked piece 8 on the upper surface of the lower stacked piece 7, and then fit one heat insulation panel 6 into the fitting recess 15 of the other heat insulation panel 6 to form a joint piece of one heat insulation panel 6. The joining protrusion 10 of the other heat insulating panel 6 is placed on top of 9.

At this time, a gap 16 is formed on the lower surface of the bent piece 13 at the tip of the joining protrusion 10 to block capillary action.

Thereafter, a fixing tool 11 such as a self-drilling screw having a drilled portion 17 at its tip is screwed into the mounting structure member 12 from above the joining protrusion 10.

The fixing tool 11 includes a joint projecting piece 10, a joint piece 9, a heat insulating material 5 on the lower surface of the joint piece 9, a heat insulating material 5 on the upper surface of the upper stacked piece 8, and an upper stacked piece 8.
, the lower stacked piece 7 in this order and screwed into the mounting structure member 12.

In this way, the fixing tool 11 penetrates a total of six metal plates: the joining piece 9, the joining protrusion 10, the upper and lower pieces of the upper stacked piece 8, and the upper and lower pieces of the lower stacked piece 7, and connects them to each other. Adjacent heat insulating panels 6 can be joined together, and the heat insulating panels 6 can be firmly joined by a large number of metal plates.

In particular, when wind blows up from below, a force that lifts the insulation panel 6 as shown by the arrow in Fig. At the bottom of the joining part of the panel 6.6, the fixing tool 11 penetrates the four metal plates, the upper and lower pieces of the upper stacked piece 8 and the upper and lower pieces of the lower stacked piece 7, so that a strong joint is created between the multiple metal plates. In addition, since the upper and lower stacked pieces 7 and 8 are shaped like folded metal plates, they are difficult to deform.
As a result, the above-mentioned forces can be effectively dealt with.

In addition, since the heat insulating material 5 is present on the lower surface of the joint piece 9, and the heat insulating material 5 is further present in the lower stacked piece 7 and the upper stacked piece 8, the joints of the adjacent heat insulation panels 6 and 6 are The heat insulating materials 5 can be overlapped in the inner and outer directions, and the ends of the heat insulating materials 5.5 of both the heat insulating panels 6.6, which are sloped surfaces at this joint, can be made to overlap in the inner and outer directions, This makes it possible to ensure heat insulation at the joints of the heat insulating panels 6.6.

At this time, in order to make the ends of the insulation materials 5, 5 of the adjacent insulation panels 6.6 overlap in the inside and outside directions,
A protrusion or step is formed at the end of the heat insulating material 5 of one heat insulating panel 6, and a recess or step is formed at the end of the heat insulating material 5 of the other heat insulating panel 6. It is also possible to make the ends of the heat insulating materials 5 overlap each other in the inner and outer directions by fitting the protrusion and the recess or fitting the protrusion and the recess.

However, when the protrusion and the recess are fitted together or the protrusion and the recess are fitted together in this way,
These fitting operations need to be performed when connecting the insulation panels 6.6, which takes time and effort, and furthermore, the dimensional relationship between the protrusion and the recess and the dimensional relationship between the protrusion and the recess are difficult. If there is a large error in the dimensions, it may not be possible to fit them together, and the insulation panel 6 will be required to be manufactured with accurate dimensions, which is extremely disadvantageous.

In FIG. 5, the heat insulating panel 6 is bonded and fixed in the same manner as described above using bolts and nuts as the fasteners 11.

18 is a rubber gasket, and 19 is a plastic cap.

Since the joining structure of the heat insulating panels of the present invention has the above-mentioned configuration, the heat insulating panels can be connected by penetrating the fasteners through a large number of metal plates, and a strong connection can be achieved. At the joint of the panel, the insulation material on the inner surface of the joint piece, the insulation material inside the lower stacked piece and the upper stacked piece, and the side edges of the insulation material are located so that they overlap in the inside and outside direction, and the insulation panel It has excellent heat insulation properties at the joints.

Moreover, by forming the end faces of the ends of the heat insulating material into inclined surfaces, the side ends of the heat insulating material overlap each other in the inner and outer directions as described above, so that the protrusions and recesses, the protrusions and the recesses, etc. Unlike the case where the heat insulating panel is provided with a heat insulating material, there is no need for effort for fitting, and the construction is easy, and the dimensions of the heat insulating panel are not required to be particularly accurate.
