The fixing structure of the heat insulating panel of the present invention can be applied to, for example, a container 1 for storing objects in the internal space 2, 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 heat insulating panel fixing structure according to an embodiment of the present invention is applied. 2A is a partial cross-sectional view of the fixing structure, and FIG. 2B is an enlarged view of a portion X in FIG. 2A. FIG. 3A is a partial front view of the fixing structure, and FIG. 3B is an enlarged view of a portion Y in FIG. 3A. 4A to 4C are front views showing three examples of the heat insulating panel 20 having different dimensions.

  First, a schematic configuration of the heat insulating panel fixing structure will be described with reference to these drawings.

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

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

  Adjacent portions 30 of the adjacent heat insulating panels 20 and 20 are attached so that the longitudinal side ends 24 of the heat insulating panels 20 are arranged on the top surface 12.

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

  A metal corrugated material in which ridges 11 and grooves 13 are alternately arranged as a base material 10 is provided on two opposing walls 3 and 3 of the outer shell of the container 1 in FIG. It is arranged so that the direction in which 11 extends is the vertical (vertical) direction. The heat insulating panel 20 is fixed so as to be in contact with the top surface 12 of the ridge 11 of the base material 10 and to straddle between the plurality of ridges 11 (see FIGS. 2 and 3). Doors 5 and 5 are formed in the other walls 4 and 4, and a flat base material 6 is disposed in other portions of the other walls 4, and the heat insulating panel 20 is fixed to the inner surface thereof. ing. In FIG. 3A, the top surface 12 of the ridge 11 is cross-hatched in order to make each part of the corrugated base material 10 easily understandable from a front view.

  The corrugated material (base material 10) is formed by welding and joining unit corrugated materials in which, for example, the ridge portions 11 and the groove portions 13 have two concavo-convex periods for two periods at the time of assembling the container 1. It is formed as 10. If it is a unit corrugated material for two periods of irregularities, it can be formed in a size that can be easily handled. As shown in FIGS. 2A and 2B, the corrugated material according to the present embodiment has a linear joint 14 formed substantially at the center of the ridge 11 in the width direction.

  As the heat insulating panel 20, rectangular panels having various dimensions illustrated in FIGS. 4A to 4C are used. The short 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. One type of the heat insulating panels 20, 20, 20 of these various sizes 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 at a substantially central portion inside. As described above, the foamed resin 22 is arranged not only on both sides in the longitudinal direction of the central vacuum heat insulating material 21 but also on both sides in the transverse direction and up and down. It functions as a heat insulating material, and the vacuum heat insulating material 21 is protected by the foamed resin 22.

  As the vacuum heat insulating material 21, a material formed by externally covering a core material with a gas barrier packaging material and performing vacuum suction can be used. In particular, 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 (foamed) foams such as hard urethane foam, foamed polyethylene, and foamed polystyrene are used.

  4 (a), (b), and (c), any of the heat insulating panels 20, 20, 20 can be cut at both side ends 24, 24 in the longitudinal direction so as to be cut in parallel with the short side. It has substitute parts 23 and 23. The cutting margins 23, 23 are portions of the foamed resin 22 around the vacuum heat insulating material 21 which are disposed at the longitudinal side ends 24, 24. Therefore, the vacuum heat insulating material 21 is not damaged even if it is cut within the range indicated by the double-headed arrow in the drawing at the cutting margins 23, 23, and is used as the heat insulating panel 20 whose longitudinal dimension is smaller than the original dimension. be able to. In this way, by cutting and removing a part of the outside of the cutting margins 23, 23, the heat insulating panel 20 can be changed to various lengths and used while keeping the function of the vacuum heat insulating material 21.

  In order to prevent the vacuum heat insulating material 21 from being erroneously damaged, the heat insulating panel is shown so that the area of the cutting margins 23, 23, in particular, the area where the foamed resin 22 on the side ends 24, 24 side in the longitudinal direction is arranged can be understood. It is desirable that a mark line is provided on the front and back surfaces of the surface of the substrate 20, and the like. In addition, the area of the cutting margins 23 may be different between the left and right, or one of the cutting margins 23 may not be cut.

  As shown in FIGS. 2 (a) and 3 (a), the heat insulating panel 20 has the internal space 2 of the base material 10 in a state where the longitudinal direction is transverse to the direction in which the ridge 11 extends. It is attached to the side surface. The heat insulating panel 20 is fixed to the base material 10 on the top surface 12 of the ridge 11.

  In addition, when the heat insulating panels 20 are connected in a horizontal direction, the ends of the heat insulating panels 20, 20 are connected to each other on the top surface 12 of the ridge 11, as shown in FIGS. 2 (a) and 3 (a). 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 ridge portion 11 is fixed to each of the left and right sides such that the longitudinal ends of the two heat insulating panels 20, 20 are adjacent to each other.

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

  Further, regarding the right heat insulating panel 20 in the continuous portion 30 in FIG. 2A, the cutting of the side end 24 is not adjusted as shown in FIG. 3A. As described above, in the example illustrated in FIG. 2A, one of the side end portions 24 of the adjacent heat insulating panels 20 in the continuous portion 30 is cut and adjusted, and the other is not adjusted. Of course, depending on the corrugated material (base material 10) having various irregularities, both of the adjacent side ends 24, 24 may be cut and adjusted, or both of the adjacent side ends 24, 24 may be both cut and adjusted. The cutting adjustment need not be performed. Further, other various sizes of heat insulating panels 20 may be used.

  The heat-insulating panel 20 is fixed to the top surface 12 of the ridge 11 using a double-sided tape 31 and an adhesive 32. The double-sided tape 31 performs initial bonding, and the adhesive 32 performs long-term bonding. This specific fixing procedure will be described later in the description of FIG.

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

  The heat insulating panel 20 is fixed to the top surface 12 of the ridge 11 using the double-sided tape 31 and the adhesive 32 as described above. Specifically, as shown in FIG. 3B, the double-sided tape 31 is attached at intervals in the vertical direction at the portion of the top surface 12 where the heat insulating panel 20 is to be attached, and the adhesive 32 is The tape 31 is applied to an appropriate portion of the non-sticking portion. The double-sided tape 31 is used for the purpose of initial bonding until the adhesive 32 is cured.

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

  First, an operator measures whether or not both side end portions 24 of the heat insulating panel 20 in the longitudinal direction can be arranged on the ridge portion 11 by judging dimensions. Next, when the longitudinal side end 24 of the heat insulating panel 20 protrudes toward the groove 13, one of the portions (cut allowance 23) of the foamed resin 22 located on the longitudinal side end 24 side. Cut and remove the part. Then, the length of the heat insulating panel 20 is adjusted so that the side end 24 to be the cut end 25 is disposed on the top surface 12 of the ridge 11. Of course, in the case where the side end portion 24 has such a size that does not protrude toward the groove portion 13, the cutting is unnecessary.

  After performing the length adjusting step, a fixing step of arranging the heat insulating panel 20 so that its longitudinal direction is orthogonal to the direction of the ridge 11 and attaching the heat insulating panel 20 to the top surface 12 of the ridge 11 is performed. When the length is adjusted by cutting, the side end 24 that is to be the cut 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) Side end 24 is affixed to top surface 12.

  Before the fixing step, a pasting preparation step may be performed. That is, in the pasting preparation step, the double-sided tape 31 and the adhesive 32 are separated from each other at a position corresponding to the width dimension of the heat insulating panel 20 on the top surface 12 as shown in FIG. It may be provided in advance. FIG. 3B shows an example in which the heat insulating panel 20 is attached to the joint 14 of the ridge 11 of the base material 10. The same applies to the ridge 11 without the joint 14. .

  If the double-sided tape 31 and the adhesive 32 are prepared and arranged in advance on the side of the base material 10 as described above, the double-sided tape 31 and the adhesive 32 come into contact with each other when the heat insulating panel 20 is attached. 31 can be prevented from becoming unable to be initially bonded.

  In addition, the paste preparation step may be performed at least before the fixing step. That is, the attaching preparation step may be performed before the execution of the length adjustment step or after the execution of the length adjustment step. Further, the application of the adhesive 32 may be performed in a divided manner, for example, only the application of the double-sided tape 31 is performed before the execution of the length adjustment step, and the application of the adhesive 32 is performed after the execution of the length adjustment step.

  Further, the fixing method of the heat insulating panel is a procedure of fixing the heat insulating panel 20 in a horizontal direction, and since the heat insulating panel 20 has a constant short dimension even when cut, the double-sided tape 31 and the adhesive 32 Can be easily determined in the ridge portion 11 where the arrangement is prepared. As a result, the work of attaching the heat insulating panel 20 to the ridge 11 can be performed reliably and efficiently.

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

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

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

  In addition, since the heat insulating panel 20 includes the cutting margin 23 that can be cut and removed at the side end portions 24, 24, the fixing is performed in accordance with the base material 10 having various projections and depressions of the ridge 11 and the groove 13. The method can be performed. That is, as shown in FIGS. 4A to 4C, since the cutting margin 23 has a certain length in the longitudinal direction, the cutting length may be variously changed in accordance with the uneven period of the base material 10. .

  In the above embodiment, the case where the heat insulating panel 20 is provided on the wall portion 3 is exemplified. However, even in the case of the outer portion other than the wall portion 3 such as a floor portion or a ceiling portion, the fixing method and the fixing structure for the corrugated material are not limited. The same as described above can be applied.
