Embodiments of the present invention will be described below with reference to the accompanying drawings.
First, a basic configuration of a heat insulating material according to an embodiment of the present invention will be described.

  In this heat insulating material 10, a plurality of foams 11, 11,... Obtained by extrusion foaming a foam material are arranged and integrated so that the extrusion direction 13 is the same direction, and in a direction orthogonal to the extrusion direction 13. A heat insulating material having a cut surface 12 that has been cut. The cut surface 12 is a heat insulating surface against heat passage.

  This heat insulating material 10 is a plate-shaped heat insulating material used for floors, walls, ceilings, doors, and the like. For example, the heat insulating material 10 is constructed between the joists 1 and 1 under the floor (see FIG. 2). 2 in FIG. 2 is a large pull that supports the joists 1 and 1 from below.

  The heat insulating material 10 shown in FIG. 1 consists of a plate-like body in which a plurality of foams 11, 11,. That is, as shown in FIG. 1, this plate-like body is formed by arranging a plurality of rod-shaped (columnar) 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 FIGS. 6 and 7 to be described later are schematic views. In these drawings, the foam 11 constituting the heat insulating material 10 is illustrated as having a large diameter. On the other hand, in the heat insulating material 10 shown in FIGS. 3 to 5, the diameter of the foam 11 is smaller than that in FIG. 1, but the foam 11 may have any diameter.

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

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

  The plurality of foams 11, 11,... Constituting the heat insulating material 10 are not easily expanded and contracted in the extrusion direction 13, but are easily expanded and contracted in the direction orthogonal to the extrusion direction 13. Therefore, when the heat insulating material 10 is fitted between the joists 1 and 1, it can be easily shrunk in the lateral direction, and can be easily fitted (see FIGS. 2A to 2C). Further, since the heat insulating material 10 is elastically contracted when fitted between the joists 1 and 1, it is firmly held between the joists 1 and 1 by a restoring force.

  Moreover, since the heat insulating material 10 is easily contracted in any direction as long as it is a direction orthogonal to the extrusion direction 13, the applicable range is wide. If they do not match the dimensions between the frame bodies such as joists 1, 1, etc., they may be cut and used accordingly. Even if the side surface is cut, the ease of contraction does not change, and it can be applied to the dimensions between frames quickly and easily on site.

  Next, a heat insulating material mounting structure for various members will be described with reference to FIGS.

  Each of the heat insulating materials 10, 10, and 10 shown in FIGS. 3A to 3C has a plurality of foams 11, 11,... Obtained by extruding and foaming a foam material so that the extrusion directions 13 are the same direction. It is arranged and integrated. The heat insulating material 10 has the cut surface 12 cut | disconnected in the direction orthogonal to the extrusion direction 13 of the foam 11, 11, .... The mounting structure of these heat insulating materials is such that the cut surface 12 of the heat insulating material 10 is attached to the surface material 22 for mounting.

  Moreover, the attachment structure of the heat insulating material shown in FIGS. 3 (a) and 3 (b) among them is that the heat insulating material 10 having the cut surface 12 cut in the direction orthogonal to the extrusion direction 13 is attached to the frames 21 and 21. It is also the mounting structure of the heat insulating material to be attached. The attachment structure attaches the heat insulating material 10 so that the cut surface 12 is arranged on the opening side of the frames 21 and 21.

  In other words, the heat insulating material mounting structure may be a structure fitted between the frame bodies 21, 21 or may be a structure not using the frame body 21. In FIG. 3A, the face material 22 is individually attached to both the cut surfaces 12, while in FIG. 3B and FIG. 3C, the face material 22 is placed on the entire circumference of the heat insulating material 10. It is stuck to wrap around. That is, in the case of FIG. 3B, the face material 22 is attached to the outer surfaces of both frame bodies 21, 21, and in the case of FIG. It is attached.

  Thus, what attached the heat insulating material 10 to the face material 22 can be used as the integrated heat insulating panel 20. FIG. Such a heat insulating panel 20 is used for various products, and may be used for, for example, a door, a partition, or the like, or all or a part of plate members 31 and 31 constituting a box such as the bag 30 shown in FIG. You may use for.

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

  Moreover, as the heat insulation panel 20 used for the plate material 31 of the eaves 30, any of FIGS. 3A to 3C may be used, or a combination thereof may be used. For example, for the plate member 31 constituting the bottom portion, more robust heat insulating panels 20 and 20 having the frame body 21 (see FIGS. 3A and 3B) may be used.

  As described above, if the plate members 31,... Constituting the heel 30 are formed by the main heat insulating panels 20,. The performance of a cooling agent such as ice can be maintained.

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

  As another attachment structure of the heat insulating material, a structure in which the face material 22 is attached only to the cut surface 12 of the heat insulating material 10 as shown in FIG. That is, the heat insulating material mounting structure (heat insulating panel 20) is different from that shown in FIG. 3C, and the face material 22 is not attached to both outer side surfaces of the heat insulating material 10, and some of the foams. The face material 22 is stuck 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, since both outer side surfaces of the heat insulating material 10 protrude beyond the face material 22, the protruding foam 11 can be contracted by an external force and fitted into the frame bodies 21 and 21. it can. This heat insulation panel 20 can be used as the partition part 41 for partitioning the warm space 42 and the cold space 43 of the portable warm refrigerator 40 as shown in FIG.5 (b), for example.

  If the heat insulating panel 20 shown in FIG. 5A is used as the partitioning portion 41, it is difficult for heat to be transmitted between the warm space 42 and the cold space 43 in one space surrounded by the side plates 44, 44. Can be partitioned easily. In addition, the mounting position of the partition portion 41 can be easily changed. Thus, the portable warm 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.

  Subsequently, the manufacturing method about the heat insulating material 10 mentioned above is demonstrated, referring FIG. 6 and FIG.

  This manufacturing method includes at least a procedure for forming the foam aggregate 15 and a cutting procedure for the foam aggregate 15.

  The foam aggregate 15 is formed by adhering a plurality of foams 11, 11,... Obtained by extruding foam material to each other so that the extrusion direction 13 is the same direction. It is a procedure to do. This procedure is not shown, but as described above, a known manufacturing procedure using a mold (not shown) in which a large number of round holes are formed adjacent to each other may be adopted.

  As shown in FIG. 6, the procedure for cutting the foam aggregate 15 is to cut the foam aggregate 15 in a direction orthogonal to the extrusion direction 13 so that the cut surface 12 becomes a heat insulating surface against heat passage. Thus, the heat insulating material 10 is formed.

  Since the foam aggregate 15 shown in FIG. 6 is a plate-like one in which the rod-shaped foams 11, 11,... Are stacked in four stages, only the heat insulating material 10 having a small width dimension can be formed. In order to form the heat insulating material 10 having a large width dimension, as shown in FIG. 7, after the plurality of plate-like foam aggregates 15, 15, 15 are bonded together, the bonding material 16 is moved in the extrusion direction 13. You may make it cut | disconnect in the orthogonal direction.

  If the manufacturing method shown in FIG. 7 is used, 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 embodiment are plate-like, but may be a thick heat insulating material using a long foam 11, and a cut surface 12 (heat insulating surface). ) Or a heat insulating material with a heat insulating surface inclined. Thus, since the heat insulating surface is formed by a set of cut faces of a plurality of foams, various shapes of heat insulating materials can be formed by variously changing the cutting method.

  In addition, 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.
