By the way, when the heat insulation panel is internally stuck to the surface of the base material on the inner space side as described above, the target base material has a corrugated shape in which ridges and grooves are alternately arranged (corrugated material). ) Is also assumed. Such substrates are often used for containers and the like.

When arranging such a corrugated material as a base material of an outer wall portion such as a wall, it is common to arrange the corrugated portions and the groove portions so that the extending directions of the ridge portions and the groove portions are aligned with the vertical direction.

However, since the corrugated material has various concavo-convex periods, there is a possibility that the heat insulating panel having a fixed width may not be bridged and arranged between the ridges even if it is attempted to be vertically attached. That is, the widthwise end of the heat insulating panel may not be able to be arranged on the ridge. In such a case, at least one end protrudes between the ridges (that is, the space on the front side of the groove), so that the heat insulation panels are connected so that they are adjacent to each other on the top surface of the ridges. You cannot do it.

The fixing structure of the heat insulating panel of the present invention can be applied to, for example, a container 1 that stores an object in the internal space 2, and particularly a container (house) 1 that uses the container 1 for living.

FIG. 1 is a cross-sectional view of a container 1 to which a fixing structure for a heat insulating panel according to an embodiment of the present invention is applied. FIG. 2A is a partial cross-sectional view of the fixing structure, and FIG. 2B is an enlarged view of the X portion of FIG. 2A. FIG. 3A is a partial front view of the same fixing structure, and FIG. 3B is an enlarged view of the Y portion of FIG. 3A. 4A to 4C are front views showing three examples of the heat insulating panel 20 having different sizes.

First, based on these drawings, a schematic structure of the fixing structure of the heat insulation panel will be described.

This fixing structure of the heat insulating panel has a vacuum heat insulating material 21 in the center on a surface of the base material 10 arranged as an outer portion forming the inner space 2 on the inner space 2 side and foams on both sides in the longitudinal direction. This is a fixed structure in which the heat insulating panel 20 having the resin 22 is attached and fixed.

The base material 10 has a corrugated shape in which projecting ridges 11 protruding toward the inner space 2 side and having a substantially flat top surface 12 and grooves 13 parallel to the ridges 11 are arranged alternately. The heat insulating panel 20 is arranged so that its longitudinal direction is orthogonal to the extending direction of the ridge 11, and is attached to the top surface 12 of the ridge 11.

Regarding the continuous installation portions 30 of the adjacent heat insulation panels 20, 20, the side edges 24 in the longitudinal direction of the heat insulation panels 20 are attached so as to be arranged on the top surface 12.

Next, the detailed structure of the fixing structure of the heat insulating panel will be described.

The corrugated material made of metal, in which the ridges 11 and the grooves 13 are alternately arranged as the base material 10, is formed on the two opposing walls 3 and 3 of the outer shell of the container 1 of FIG. It is arranged so that the direction in which 11 extends is the vertical (vertical) direction. Then, the heat insulating panel 20 is fixed so as to come into contact with the top surface 12 of the protruding portion 11 of the base material 10 and to straddle the plurality of protruding portions 11 and 11 (see FIGS. 2 and 3 ). Further, doorways 5, 5 are formed in the other wall portions 4, 4, a flat base material 6 is arranged in other portions of the other wall portion 4, and the heat insulating panel 20 is fixed to the inner surface thereof. ing. In addition, in FIG. 3A, in order to make each part of the corrugated substrate 10 easy to understand in a front view, the top surface 12 of the ridge 11 is cross-hatched.

The corrugated material (base material 10) is, for example, a base corrugated material formed by welding and joining unit corrugated materials in which the protrusions and recesses 11 and the grooves 13 are continuous for two cycles at the protrusions 11 when assembling the container 1. Formed as 10. A unit corrugated material for two cycles of unevenness can be formed in a size that can be easily handled. In the corrugated material according to the present embodiment, as shown in FIGS. 2A and 2B, a linear joint portion 14 is formed substantially at the center of the protrusion 11 in the width direction.

As the heat insulation panel 20, rectangular ones having various dimensions illustrated in FIGS. 4A to 4C are used. The short-side dimension of each of the heat-insulating panels 20, 20, 20 is substantially the same, for example, 900 mm, and the longitudinal dimension is different. As for the heat insulation panels 20, 20, 20 of these various sizes, one type may be used for one container 1, or a plurality of types may be used in combination.

Each of the heat insulating panels 20, 20, 20 has a vacuum heat insulating material 21 in the center portion inside. As described above, the foamed resin 22 is not only arranged on both sides in the longitudinal direction of the central vacuum heat insulating material 21, but also on both sides in the lateral direction and also on the upper and lower sides. It functions as a heat insulating material, and the foamed resin 22 protects the vacuum heat insulating material 21.

As the vacuum heat insulating material 21, for example, a material formed by covering the core material with a packaging material having a gas barrier property and sucking it in vacuum can be used. Particularly, in the example of the present embodiment, a thin panel body having a substantially rectangular shape in plan view is used. As the foamed resin 22, various foam-based (foam-based) resins such as hard foamed urethane, foamed polyethylene, and foamed polystyrene are used.

Any of the heat insulating panels 20, 20, 20 shown in FIGS. 4(a)(b)(c) can be cut at both side end portions 24, 24 in the longitudinal direction so as to be cut parallel to the short side. It has a substitute section 23, 23. The cutting margin portions 23, 23 are portions of the foamed resin 22 around the vacuum heat insulating material 21 that are arranged at the side end portions 24, 24 in the longitudinal direction. Therefore, in the cutting margins 23, 23, the vacuum heat insulating material 21 is not damaged even if cut within the range indicated by the double-headed arrow in the figure, and is used as the heat insulating panel 20 having a smaller longitudinal dimension than the original dimension. be able to. By cutting and removing a part of the outside of the cutting margins 23, 23, the heat insulating panel 20 can be used by changing its length to various lengths while keeping the function of the vacuum heat insulating material 21.

In order to avoid accidentally damaging the vacuum heat insulating material 21, the area of the cutting margins 23, 23, particularly the range where the foamed resin 22 on the side end portions 24, 24 in the longitudinal direction is arranged, can be seen so that the heat insulating panel can be seen. Marking lines are preferably attached to the front and back surfaces of 20. Further, the regions of the cutting margin portions 23, 23 may be different on the left and right, or one of them may not be cut.

As shown in FIG. 2A and FIG. 3A, the heat insulating panel 20 has an internal space 2 of the base material 10 in a state in which the longitudinal direction is laterally oriented so as to be orthogonal to the extending direction of the protrusion 11. It is attached to the side surface. The heat insulating panel 20 is fixed to the base material 10 at the top surface 12 of the protrusion 11.

Further, when the heat insulating panels 20 are arranged in a row in the lateral direction, as shown in FIGS. 2( a) and 3 (a ), the ends of both heat insulating panels 20 and 20 are at the top surface 12 of the ridge 11. It is attached so as to be in a butt state. That is, in the continuous portion 30 of the heat insulating panel 20, the top surface 12 of the protruding portion 11 is fixed to each of the left and right so that the side edges in the longitudinal direction of the two heat insulating panels 20, 20 are adjacent to each other.

In this continuous portion 30, one of the heat insulation panels 20 (the left heat insulation panel 20 in the example of FIG. 2A) is cut at an appropriate position so that the side end portion 24 is arranged on the top surface 12. It is designed to be attached after the length has been adjusted. In this way, the heat insulating panel 20 is fixed so that the cut end portion 25 is arranged on the top surface 12 as shown in FIG.

As for the heat insulating panel 20 on the right side in the continuous portion 30 of FIG. 2A, the cutting of the side end portion 24 is not adjusted as shown in FIG. 3A. Thus, in the example shown in FIG. 2A, one of the side end portions 24, 24 of the two adjacent heat insulating panels 20, 20 in the continuous portion 30 is cut and adjusted, and the other is not cut and adjusted. Of course, both of the side edges 24, 24 adjacent to each other may be cut and adjusted, or both of the side edges 24, 24 adjacent to each other may be adjusted in accordance with the corrugated material (base material 10) having various irregular periods. The cutting may not be adjusted. In addition, various other sized insulation panels 20 may be used.

A double-sided tape 31 and an adhesive 32 are used to fix the heat insulating panel 20 to the top surface 12 of the protrusion 11. The double-sided tape 31 is responsible for initial adhesion, and the adhesive 32 is responsible for long-term adhesion. This specific fixing procedure will be described later in the description of FIG.

In addition, in the joint portion 14 of the base material 10 such as the X portion of FIG. 2A, the welding mark 15 may bulge on the top surface 12 of the ridge portion 11 as shown in FIG. 2B. is there. In such a case, as shown in FIG. 2( b ), double-sided tape 31 may be overlapped on each surface of the top surface 12 on both sides of the welding mark 15 by the bulging height of the welding mark 15. The heat insulating panel 20 can be attached to the ridge 11 so as to avoid the welding mark 15.

The heat insulating panel 20 is fixed to the top surface 12 of the protrusion 11 by using the double-sided tape 31 and the adhesive 32 as described above. Specifically, as shown in FIG. 3B, double-sided tapes 31 are attached at intervals in the up-down direction and adhesives 32 are provided on both surfaces of the top surface 12 at the attachment target site of the heat insulating panel 20. The tape 31 is applied to a proper place on the non-adhered portion. The double-sided tape 31 is used for the purpose of initial adhesion until the adhesive 32 is cured.

The method of fixing the heat insulation panel 20 for attaching the heat insulation panel 20 to the base material 10 as described above includes performing the following procedure (process).

First, the operator measures the dimensions to determine whether or not both side end portions 24 in the longitudinal direction of the heat insulating panel 20 are arranged on the ridge 11. Next, when the side end 24 in the longitudinal direction of the heat insulating panel 20 projects toward the groove 13 side, one of the portions (cutting margin 23) of the foamed resin 22 located on the side end 24 side in the longitudinal direction. Cut off parts. Then, the length of the heat insulating panel 20 is adjusted so that the side end portion 24 serving as the cut end portion 25 is arranged on the top surface 12 of the protruding portion 11. Of course, if the side end portion 24 has a size that does not project to the groove portion 13 side, the cutting is unnecessary.

After this length adjusting step is performed, a fixing step is performed in which the heat insulating panel 20 is arranged so that its longitudinal direction is orthogonal to the direction of the protruding portion 11 and is attached to the top surface 12 of the protruding portion 11. When the length is adjusted by cutting, the side end 24 which becomes the cutting end 25 is attached to the top surface 12, and when the cutting is not performed, (the original state where the cutting is not performed is performed. The side end portion 24 is attached to the top surface 12.

Further, the sticking preparation step may be performed before the fixing step. That is, in the sticking preparation step, the double-sided tape 31 and the adhesive 32 are arranged so as to be separated from each other at a portion of the top surface 12 corresponding to the width dimension of the heat insulating panel 20, as shown in FIG. 3B. It may be arranged in advance. Although FIG. 3B shows an example of attaching the heat insulating panel 20 to the joint portion 14 of the protrusion portion 11 of the base material 10, the same applies to the protrusion portion 11 without the joint portion 14. ..

If the double-sided tape 31 and the adhesive 32 are preliminarily arranged on the base material 10 side in this way, the double-sided tape 31 and the adhesive 32 come into contact with each other when the heat insulating panel 20 is attached. It is possible to avoid that 31 cannot be initially bonded.

Further, the attaching preparation step may be performed at least before the fixing step is performed. That is, the sticking preparation step may be performed either before the length adjusting step or after the length adjusting step. Furthermore, the double-sided tape 31 may be attached only before the length adjustment step is performed, and the adhesive 32 may be applied after the length adjustment step.

Further, the fixing method of the present heat insulation panel is a procedure of fixing the heat insulation panel 20 in a horizontal direction, and since the heat insulation panel 20 has a constant lateral dimension even when cut, the double-sided tape 31 and the adhesive 32 are used. It is possible to easily determine the position in the ridge portion 11 where is prepared and arranged. As a result, it is possible to reliably and efficiently carry out the attaching work on the ridge portion 11 of the heat insulating panel 20.

Further, as shown in FIG. 3B, when the heat insulating panel 20 is attached to the top surface 12 of the ridge 11 having the bulged welding mark 15, the double-sided tape 31 is used to adjust the bulging height of the welding mark 15. The adhesive 32 may be applied so as to exceed the bulging height of the welding mark 15 so as to be overlaid.

As described above, the heat insulation panel 20 can be attached to the wall portion 3 from, for example, left to right, and further, for example, from bottom to top, so that the heat insulation panel 20 can be disposed on the entire surface of the wall portion 3.

According to the method of fixing the heat insulating panel described above, the length of the heat insulating panel 20 can be adjusted by cutting the cutting margin portion 23 (the foamed resin 22 arranged on the side end portion 24 side in the longitudinal direction). The heat insulation panel 20 can be reliably connected in the part 11. Particularly, the pasting work can be extremely efficient as compared with the vertical pasting method. Further, according to the fixing structure of the heat insulation panel described above, the heat insulation panel 20 can be firmly fixed to the corrugated base material 10 in which the ridges 11 and the grooves 13 are alternately arranged.

Further, since the heat insulating panel 20 includes the cutting margin portions 23 that can be cut and removed at the side end portions 24, 24, this fixing is made corresponding to the base material 10 of various convex and concave periods of the ridges 11 and the grooves 13. The method can be carried out. That is, as shown in FIGS. 4A to 4C, since the cutting margin portion 23 has a certain length in the longitudinal direction, the cutting length may be variously changed according to the concave-convex cycle of the base material 10. ..

Although the heat insulating panel 20 is provided on the wall portion 3 in the above-described embodiment, the fixing method and the fixing structure for the corrugated material are not limited to the wall portion 3 and the outer wall portion such as the floor portion and the ceiling portion. The same as described above may be applied.
