Hereinafter, embodiments of the present invention will be described based on the attached drawings.
First, the basic configuration of a heat insulating material according to an embodiment of the present invention will be described.

  In the heat insulating material 10, a plurality of foam bodies 11, 11, ... obtained by extrusion foaming of a foam material are disposed and integrated such that the extrusion direction 13 is in the same direction, and in a direction orthogonal to the extrusion direction 13 It is a heat insulating material having a cut surface 12 which has been cut. The cut surface 12 is a heat insulation surface for heat passage.

  The heat insulating material 10 is a plate-like heat insulating material used for a floor, a wall, a ceiling, a door or the like. For example, the heat insulating material 10 is applied between the joists 1 and 1 below the floor (see FIG. 2). In addition, 3 in FIG. 2 is a rough pull which supports the joists 1, 1 from the lower side.

  The heat insulating material 10 shown in FIG. 1 is a plate-like body in which a plurality of foams 11, 11,... That is, as shown in FIG. 1, this plate-like body is a plate-like shape in which a plurality of rod-like (cylindrical) foams 11, 11,... . Although the manufacturing method of this heat insulating material 10 is mentioned later, what is necessary is just to manufacture using the metal mold | die (not shown) in which many round holes were formed adjacently. By doing so, the heat insulating material 10 which made the extrusion direction 13 the same direction like FIG. 1 can be manufactured.

  1 and 2 and later-described FIGS. 6 and 7 are schematic views, and in these figures, the foam 11 constituting the heat insulating material 10 has a large diameter. On the other hand, although the diameter of the foam body 11 of the heat insulating material 10 shown to FIGS. 3-5 is small compared with the thing of FIG. 1, the foam body 11 may be a thing of what diameter.

  As the foam material constituting the foams 11, 11, ..., for example, a polyolefin resin containing cellulose and starch is used. More specifically, for example, a foamed material containing polypropylene, paper, starch is used. Moreover, what used polyvinyl chloride (polyvinyl chloride) instead of the polypropylene, and what used wood instead of paper may be used.

  The heat insulating material 10 shown in FIG. 1 has a rectangular shape in a plan view, and can be fitted between frames such as joists 1 and 1 with the cut surface 12 directed vertically. That is, the upper and lower cut surfaces 12 of the heat insulating material 10 are the heat insulating surfaces for the heat passage between the floor and the room.

  The plurality of foams 11 11 constituting the heat insulating material 10 do not easily expand and contract in the extrusion direction 13 but easily expand and contract in the direction orthogonal to the extrusion direction 13. Therefore, when the heat insulating material 10 is inserted between the joists 1, it can be easily shrunk in the lateral direction, and the insertion can be carried out easily (see FIGS. 2A to 2C). Moreover, since the heat insulating material 10 is elastically shrunk at the time of fitting in between the joists 1, 1, it is firmly held between the joists 1, 1 by a restoring force.

  Moreover, since the heat insulating material 10 is easily shrunk in any direction if it is a direction orthogonal to the extrusion direction 13, the application range is wide. If it does not match the dimensions between the frames such as the joists 1, 1, etc., they may be cut and used accordingly. Even if the side panels are cut, the ease of contraction does not change, and the construction can be performed according to the size between the frames quickly and easily on site or the like.

  Subsequently, the attachment structure of the heat insulating material with respect to various members is demonstrated, referring FIGS. 3-5.

  In each of the heat insulating materials 10, 10, 10 shown in FIGS. 3 (a) to 3 (c), a plurality of foam bodies 11, 11,. Distributed and integrated. The heat insulating material 10 has a cut surface 12 cut in a direction orthogonal to the extrusion direction 13 of the foams 11, 11,. The attachment structure of these heat insulating materials is such that the cut surface 12 of the heat insulating material 10 is attached to the face material 22 and attached.

  Among them, the mounting structure of the heat insulating material shown in FIGS. 3 (a) and 3 (b) has the heat insulating material 10 having the cut surface 12 cut in the direction orthogonal to the extrusion direction 13 as the frames 21 and 21. It is also a mounting structure of the heat insulating material to be mounted. The mounting structure is such that the heat insulating material 10 is mounted such that the cut surface 12 is disposed on the opening side of the frames 21, 21.

  That is, as an attachment structure of a heat insulating material, the thing of the structure put in between frame 21 and 21 may be used, and the thing of the structure which does not use frame 21 may be used. 3 (a), the face material 22 is adhered to both the cutting surfaces 12 individually, while the face material 22 in FIG. 3 (b) (c) is all around the heat insulating material 10. It is stuck to be wound. That is, in the case of FIG. 3 (b), the facings 22 are attached to the outer surfaces of both the frames 21 and 21, and in FIG. 3 (c), the facings 22 are also on both outer sides of the heat insulating material 10. It is attached.

  Thus, what attached the heat insulating material 10 to the surface material 22 can be used as a heat insulation panel 20 integrated. Such a heat insulation panel 20 is used for various products, for example, may be used for a door, a partition, etc., or all or a part of the plate members 31, 31 constituting a box such as the weir 30 shown in FIG. It may be used for

  As the heat insulation panel 20 used for a door, the thing of the structure of FIG.3 (b) (c) made into the structure which covers the perimeter with a makeup material (face material 22) is aesthetically appropriate. Moreover, if the heat insulation panel 20 of FIG.3 (c) is used, since the frames 21 and 21 are not used, weight reduction and cost reduction of a door are realizable.

  Further, as the heat insulating panels 20 used for the plate members 31 of the weir 30, any of FIGS. 3A to 3C may be used, or may be used in combination. For example, as the plate member 31 constituting the bottom portion, the more robust heat insulating panels 20, 20 (see FIGS. 3A and 3B) having the frame 21 may be used.

  As described above, when the plate members 31 constituting the crucible 30 are formed by the main heat insulation panels 20, the heat insulating effect of the crucible 30 can be improved, and the dry condition is achieved over a long period of time as compared with the conventional cage. It is possible to maintain the performance of a coolant such as ice.

  Moreover, the heat insulation panel 20 is applicable also to box bodies, such as a food storage (not shown) which stores perishables, and the portable temperature refrigerator 40 (refer FIG.5 (b)).

  As another attachment structure of a heat insulating material, as shown to Fig.5 (a), what stuck the surface material 22 only to the cut surface 12 of the heat insulating material 10 is mentioned. That is, the mounting structure of the heat insulating material (the heat insulating panel 20) is different from that of FIG. 3C, and the face material 22 is not attached to both outer side surfaces of the heat insulating material 10, and a part of the foam is The face material 22 is attached to the upper and lower cut surfaces 12 so that 11 protrudes to the side of the face material 22.

  According to such a heat insulating panel 20, both outer side surfaces of the heat insulating material 10 protrude beyond the face material 22, so that the expanded foam 11 is shrunk by an external force and fitted into the frames 21, 21 or the like. it can. The heat insulation panel 20 can be used, for example, as a partition portion 41 for partitioning the hot space 42 and the cold space 43 of the portable refrigerator 40 as shown in FIG. 5B.

  If the heat insulating panel 20 shown in FIG. 5A is used as the partition portion 41, it is difficult for heat to be transmitted to the hot space 42 and the cold space 43 in a single space surrounded by the side plates 44, 44. Can easily be divided into Moreover, the mounting position of the partition 41 can be easily changed. Thus, the portable temperature refrigerator 40 can be easily formed. In addition, if the heat insulation panel 20 shown to FIG. 3 (a)-(c) is used as the side plates 44 and 44, a heat insulation effect can be improved further.

  Next, a method of manufacturing the above-described heat insulating material 10 will be described with reference to FIGS. 6 and 7.

  This manufacturing method is formed by executing at least a forming procedure of the foam aggregate 15 and a cutting procedure of the foam aggregate 15.

  The procedure for forming the foam aggregate 15 is such that the foam aggregate 15 is formed by adhering a plurality of foams 11, 11,... Obtained by extruding and foaming foam materials so that the extrusion direction 13 becomes the same direction. Procedure. Although this procedure is not illustrated, as described above, a known manufacturing procedure using a mold (not illustrated) in which a large number of circular holes are formed adjacent to each other may be employed.

  The cutting procedure of the foam aggregate 15 is to cut the foam aggregate 15 in the direction orthogonal to the extrusion direction 13 as shown in FIG. Thus, the heat insulating material 10 is formed.

  Since the foam aggregate 15 shown in FIG. 6 is in the form of a plate in which rod-like foams 11, 11,... Are overlapped in four steps, only the heat insulating material 10 having a small width can be formed. In order to form the heat insulating material 10 having a large width dimension, as shown in FIG. 7, after pasting a plurality of plate-like foam aggregate members 15, 15, 15 in the extrusion direction 13 It may be cut in the orthogonal direction.

  By using the manufacturing method shown in FIG. 7, the heat insulating material 10 having a large heat insulating surface can be manufactured.

  The various heat insulating materials 10, 10,... According to the above embodiments are plate-like, but may be a thick heat insulating material formed by using a longer foam 11, and the cut surface 12 (heat insulating surface The heat insulating material which has a level | step difference may be the heat insulating material which the heat insulation surface inclined. As described above, since the heat insulating surface is formed of a collection of a plurality of foam kerfs, it is possible to form a heat insulating material of various shapes by variously changing the cutting method.

  Moreover, the plurality of foams 11, 11,... Constituting the heat insulating material 10 are not limited to rod-like ones, and may be plate-like ones.
