  More specifically, the wooden brick 41 is fixed to flange portions 36a and 38a located on the indoor side in the vertical frame member 36 and the first intermediate frame member 38 (see FIG. 3). The flange portions 36 a and 38 a have a plane facing the indoor side, and each plane is an installation surface on which the wooden brick 41 is installed.

  In the vertical frame member 36, a plurality of wooden bricks 41S are arranged in the longitudinal direction of the vertical frame member 36, and the lateral width W1 of these wooden bricks 41S is twice the width (width) of the flange portion 36a. It is set smaller than the dimension W2). The first intermediate frame member 38 is provided with a plurality of wooden bricks 41M arranged in the longitudinal direction of the first intermediate frame member 38. The horizontal width of the wooden bricks 41M is the length of the flange portion 38a. Is set smaller than. And each wooden brick 41S, 41M is arrange | positioned in the center position in the width direction of the said installation surface, and the protrusion from each installation surface is avoided. These wooden bricks 41 are connected blocks.

  An outer heat insulating material 45 is attached to the outer wall frame 35 so as to cover a region surrounded by the outer wall frame 35 from the indoor side. The outer wall frame 35, the wooden brick 41, the outer heat insulating material 45, and the outer wall panel 31. Thus, the outer wall panel unit 30 is configured. The outer heat insulating material 45 is made of a hard foamed urethane foam and is formed in a substantially flat plate shape as a whole. An aluminum sheet (not shown) is affixed to the outer heat insulating material 45 so as to cover the surface on the outdoor side, and the reflectance of heat is increased by the aluminum sheet.

  As shown in FIG. 3, the outer heat insulating material 45 is sandwiched between regions (the vertical frame material 36 and the first intermediate frame material 38) where the wooden brick 41 does not exist when viewed in the width direction (lateral direction) of the outer wall panel 31. 45A, and a narrow heat insulating material 45B covering a region where the wooden bricks 41 are present (a region sandwiched between both wide heat insulating materials 45A).

  Hereinafter, with reference to FIG.2 and FIG.3, the relationship between the wooden brick 41M distribute | arranged to the 1st intermediate | middle frame material 38, 45A of wide heat insulating materials, and 45 B of heat insulating materials is demonstrated.

  The wooden brick 41M is sandwiched by the wide heat insulating material 45A from both sides in the width direction of the outer wall panel 31, and the end surfaces of both the wide heat insulating materials 45A are in contact with the side surface of the wooden brick 41 (more specifically, in close contact). ing. A narrow heat insulating material 45B is disposed above and below the wooden brick 41, and the wooden brick 41 is vertically sandwiched between the two narrow heat insulating materials 45B. The narrow heat insulating material 45B is also disposed such that the end surfaces of the respective narrow heat insulating materials 45B are in contact with the upper and lower surfaces of the wooden brick 41 (specifically, in close contact with each other). That is, the wooden brick 41 </ b> M is surrounded by the wide heat insulating material 45 </ b> A and the narrow heat insulating material 45 </ b> B so that no gap is generated between the wooden brick 41 </ b> M and the outer heat insulating material 45. In the present embodiment, the degree of adhesion between the wooden brick 41 and the end surface of the outer heat insulating material 45 is obtained by bonding the wooden brick 41 and the end surface of the outer heat insulating material 45 using an adhesive or a tape. However, it is not limited to this. It is only necessary that at least the end face of the outer heat insulating material 45 is in contact, and whether or not the two are bonded is arbitrary.

  Further, the end face of the narrow heat insulating material 45B is in contact with the end faces of both wide heat insulating materials 45A sandwiching the narrow heat insulating material 45B (specifically, it is in close contact). Thereby, it is avoided that a clearance gap arises between both heat insulating materials 45A and 45B, and the fall of the heat insulation function resulting from dividing the outer side heat insulating material 45 into several pieces is suppressed.

  On the other hand, the wooden bricks 41S arranged on the vertical frame members 36 are arranged so as to straddle the adjacent vertical frame members 36 in a state where the building units are connected to the left and right as described above. It is the structure surrounded by the outer side heat insulating material 45 distribute | arranged to. Specifically, the state is sandwiched from both sides in the parallel arrangement direction of the building units by the wide heat insulating material 45A arranged in one building unit and the wide heat insulating material 45A arranged in the other building unit. Further, the two building units are narrow so as to straddle the mutually connected (adjacent) vertical frame members 36, that is, to close the gaps between the two wide heat insulating materials 45A provided with the wooden brick 41S interposed therebetween. The heat insulating material 45B is disposed, and the wooden brick 41S is sandwiched up and down by the narrow heat insulating material 45B. Since the contact relationship between the wooden brick 41S and each of the heat insulating materials 45A and 45B is the same as that of the wooden brick 41M, the description is cited.

  In addition, the boundary site | part of both the vertical frame materials 36 is covered from the indoor side by the narrow heat insulating material 45B arrange | positioned at the upper and lower sides of the wooden brick 41. FIG. By arranging the narrow heat insulating material 45B in this manner, the narrow heat insulating material 45B suppresses the movement of air through the boundary portion.

  As described in detail above, the wooden brick 41 is surrounded by the outer heat insulating material 45, and the end surface of the outer heat insulating material 45 is brought into contact with the wooden brick 41. It is possible to suppress the movement of the air through the boundary part of this and to suitably exhibit the heat insulating function by the outer heat insulating material 45. In addition, as described above, when a hard foamed urethane foam is used as the outer heat insulating material 45, it is difficult to accurately form a notch or the like according to the wooden brick 41 in the outer heat insulating material 45. Therefore, as described above, if the wooden brick 41 is surrounded by the outer heat insulating material 45 composed of a plurality of pieces, it becomes easy to allow variation in accuracy. Thereby, compared with the case where an outer side heat insulating material is notched according to the wooden brick 41, for example, it is easy to construct a heat insulating structure while preferably avoiding a gap between the outer heat insulating material and the wooden brick 41M. can do.

  Further, as shown in FIG. 2, the wooden brick 41 has a lateral width of the installation surface in the outer wall frame 35 (specifically, the vertical frame member 36 and the first intermediate frame member 38) whose horizontal width W1 is an object to be arranged. It is formed to be smaller than the dimension W2, and installation areas for the wide heat insulating material 45A are secured on both sides of the wooden brick 41 in the width direction on the same installation surface. That is, the wide heat insulating material 45 </ b> A is in contact with the installation surface together with the wooden brick 41. About the boundary part of the wooden brick 41 and the outer side heat insulating material 45, it is covered from the outdoor side by the outer wall frame 35 (specifically installation surface 35a), and the movement of the air through the said boundary part is suppressed more suitably. .

  In addition, about the thickness dimension of the outer side heat insulating material 45, it is set so that it may become equivalent to the thickness dimension (projection amount from the installation surface 35a) of the wooden brick 41, and the thickness of the outer side heat insulating material 45 increases. The contact area between the wooden brick 41 and the outer heat insulating material 45 is suitably ensured while suppressing the above.

  Next, the inner wall panel unit 50 will be described with reference to FIGS. FIG. 4 is a perspective view of the inner wall panel unit 50 as viewed from the back side (outdoor side).

  As shown in FIG. 4, the inner wall panel unit 50 includes a substantially rectangular inner wall panel 51 that forms an indoor surface. The inner wall panel 51 is composed of a gypsum board, and is formed so that its outer shape is slightly smaller than the outer wall panel 31 (see, for example, FIG. 1). An inner wall frame 55 having a lattice shape is fixed to the back surface side (outdoor surface side) of the inner wall panel 51.

  The inner wall frame 55 is configured by connecting a plurality of frame materials made of wooden square materials to each other. Specifically, the inner wall frame 55 is disposed along the vertical frame members 56 provided along both ends of the inner wall panel 51 in the width direction of the inner wall panel 51 and along both ends of the inner wall panel 51 in the vertical direction. And a horizontal frame member 57 that connects the vertical frame members 56 and an intermediate frame member 58 that is provided between the vertical frame members 56 and connects the horizontal frame members 57.

  The vertical frame member 56 and the intermediate frame member 58 face each other from the indoor side with respect to the vertical frame member 36 and the first intermediate frame member 38 of the outer wall frame 35 in the attached state of the inner wall panel unit 50. In each frame member 56 to 58 of the inner wall frame 55, a bulging portion 59 that bulges to the wooden brick 41 side (outdoor side) is paired to each wooden brick 41 at a portion facing the wooden brick 41 from the indoor side. 1 to correspond to each other. The bulging portion 59 and the wooden brick 41 are fixed using nails or the like in a state where the bulging portion 59 is in contact with the wooden brick 41, so that the inner wall panel unit is attached to the outer wall panel unit 30. 50 is assembled (see FIG. 2).

  An in-frame region surrounded by the vertical frame member 56 and the horizontal frame member 57 is divided into two by an intermediate frame member 58. In each of the divided areas, a hard inner heat insulating material 65 having a flat plate shape is disposed. The outer heat insulating material 45 and the inner heat insulating material 65 constitute a heat insulating portion of the wall 20.

  The inner heat insulating material 65 is made of rigid urethane foam, and its outer shape is determined in accordance with the inner region of the frame so that almost the entire area of the edge portion is in contact with the inner surface of the inner wall frame 55. And the surface facing the inner wall panel 51 in the inner heat insulating material 65 is bonded to the inner wall panel 51 so as to be integrated with the inner wall panel 51. In addition, although the aluminum sheet is affixed on both the plate | board surfaces of the inner side heat insulating material 65, the description and illustration regarding the said aluminum sheet are abbreviate | omitted.

  As shown in FIG. 2, the thickness dimension T of the inner heat insulating material 65 is set to be smaller than the thickness dimension (dimension in the wall thickness direction) S of the inner wall frame 55 from the inner wall panel 51. The region is accommodated in a state in which the protrusion to the outer wall panel unit 30 side is suppressed. As already described, the thickness dimension of the wooden brick 41 is set to be equal to the thickness dimension of the outer heat insulating material (see FIG. 2), and the inner wall panel unit 50 with respect to the outer wall panel unit 30. In a state where is assembled, a predetermined gap (intra-wall space) is formed between a portion where the bulging portion 59 is not formed on the outer surface of the inner wall frame 55 and the outer heat insulating material 45. Yes. That is, the thickness dimension T of the inner heat insulating material 65 is set to be smaller than the separation dimension D between the outer heat insulating material 45 and the inner wall panel 51, and the inner heat insulating material 65 is disposed closer to the inner wall panel 51. A predetermined gap is formed between the inner heat insulating material 65 and the outer heat insulating material 45.

  In the present embodiment, this gap is utilized as an arrangement area for the electric wiring WH, and means for restricting the arrangement area for the electric wiring WH so as not to be smaller than a preset size is employed. It is one of the features. Hereinafter, such means will be described with reference to FIG. 2, FIG. 3 and FIG. FIG. 5 is a schematic view showing the relationship between the outer heat insulating material and the wiring.

  As shown in FIG. 3, a plurality of protrusions 48 projecting toward the inner heat insulating material 65 are formed on the surface facing the indoor side of the outer heat insulating material 45. The protrusions 48 are arranged along the periphery of the outer heat insulating material 45, and the tip portions of the protrusions 48 are in contact with the outer surface of the inner heat insulating material 65 so that the gap is not reduced. (See FIG. 2). That is, the protrusion 48 has a function as a spacer.

  Further, as shown in FIG. 5, by arranging the protrusions 48 vertically and horizontally, the degree of freedom in setting the wiring path is improved when the electric wiring WH is disposed in the gap. In the present embodiment, the electric wiring WH1 as the power line and the electric wiring WH2 as the signal line are provided in the same gap, but the wiring paths are connected to each other by using the protrusions 48. By arranging so as not to cross each other, the distance between the electric wires WH1 and WH2 is prevented from becoming excessively small. As a result, the inconvenience that noise is generated in the electric wiring WH2 due to the influence of the electric wiring WH1 is less likely to occur.

  Here, the manufacturing and assembling work of the wall 20 will be described with reference to FIG. 3 again. In the following description, the case where the wall 20 is configured by one outer wall panel unit 30 and one inner wall panel unit 50 will be described for convenience.

  First, each panel unit 30 and 50 is manufactured in a factory. Specifically, the outer wall frame 35 is fixed to the outer wall panel 31, and a part (the wooden brick 41 </ b> M) of the plurality of wooden bricks 41 is attached to the outer wall frame 35. Thereafter, the outer heat insulating materials 45A and 45B are arranged so as to surround the wooden brick 41, and the outer heat insulating materials 45A and 45B are attached to the outer wall frame 35 to construct the outer wall panel unit 30. Further, the inner wall panel 55 is constructed by attaching the inner wall frame 55 and the inner heat insulating material 65 to the inner wall panel 51.

  The outer wall panel unit 30 and the inner wall panel unit 50 manufactured at the factory are transported to a construction site or the like, and the outer wall panel unit 30 is fixed to the building 10 (specifically, the floor beam 11 and the ceiling beam 12).

  Next, the electric wiring WH is hooked (attached) to the protrusion 48. As a result, the electric wiring WH is supported by the protrusions 48, and the electric wiring WH is prevented from dropping off from the outer wall panel unit 30 (protrusions 48).

  After completing the arrangement of the electrical wiring WH, the inner wall panel unit 50 formed by fixing the inner wall frame 55 and the inner heat insulating material 65 to the inner wall panel 51 is attached to the outer wall panel unit 30. Thereby, the front-end | tip of the processus | protrusion 48 contact | abuts with respect to the inner side heat insulating material 65, and the accommodation area | region for electrical wiring WH will be formed.

  As mentioned above, according to the structure of this embodiment explained in full detail, there exist the following outstanding effects.

  By arranging the outer heat insulating material 45 and the inner heat insulating material 65 side by side between the outer wall panel 31 and the inner wall panel 51 and forming a gap between the two heat insulating materials 45, 65, the same gap is formed in the electric wiring WH. It can be used as an installation area.

  The electrical wiring WH arranged in the gap between the both heat insulating materials 45 and 65 is drawn into the room through a through hole 68 formed in the inner heat insulating material 65. That is, the through hole for introducing the electric wiring WH is formed in the inner heat insulating material 65 but not formed in the outer heat insulating material 45. By adopting such a configuration, it is possible to avoid the region on the outer wall panel 31 side and the region on the inner wall panel side from being connected through the through hole, and to suppress a decrease in the heat insulating function.

  Particularly in the present embodiment, since the thickness dimension T of the inner heat insulating material 65 is set smaller than the separation dimension D between the outer heat insulating material 45 and the inner wall panel 51, the following specification changes and the like on the wall 20 are suitable. Acceptable. Specifically, the outer heat insulating material 45 is disposed so that the surface on which the protrusion 48 is formed faces the indoor side, but this is reversed so that the surface on which the protrusion 48 is formed faces the outdoor side. By disposing, the inner heat insulating material 65 can be disposed in a state where the inner heat insulating material 65 comes into contact with the outer heat insulating material 45. In other words, when a gap is to be formed between the inner wall panel 51 and the inner heat insulating material 65 in accordance with the building specifications, for example, a fixed object (fixed panel or the like) for fixing a speaker, a shelf or the like to the inner wall is desired. In this case, the object to be fixed can be disposed in the gap between the inner wall panel 51 and the inner heat insulating material 65. Thereby, a heat insulating material and the other structure arrange | positioned in a wall can coexist suitably.

  By disposing the protrusions 48 as spacers between the two heat insulating materials 45 and 65, it is avoided that the gap between the heat insulating materials 45 and 65 becomes smaller than a preset size. Thereby, even if it is set as the structure which distribute | arranges the electrical wiring WH in the clearance gap between both the heat insulating materials 45 and 65, it can make it difficult to produce the problem that the said electrical wiring is compressed by the reduction | decrease etc. of a clearance gap. The protrusions 48 are scattered throughout the outer heat insulating material 45. Thereby, the gap maintenance function mentioned above is exhibited suitably.

  When the wall 20 is assembled, the inner wall panel unit 50 is attached to the outer wall panel unit 30. At this time, a protrusion 48 is provided on the outer wall panel unit 30 side fixed to the housing, and the electric wiring WH is entangled with the protrusion 48 so that the electric wiring WH is supported by a hand or the like when the inner wall panel unit 50 is attached. There is no need. Therefore, it is possible to contribute to facilitating the assembly work of the wall 20.

  The outer heat insulating material 45 is divided into a plurality of pieces (wide heat insulating material 45 </ b> A and narrow heat insulating material 45 </ b> B), and the end surfaces of these pieces are in contact with the peripheral surface of the wooden brick 41. Thereby, it is avoided that a clearance gap arises between the wooden brick 41 and the outer side heat insulating material 45, and the fall of a heat insulation function is suppressed.

  In particular, when the outer heat insulating material 45 is made of rigid urethane foam, the outer heat insulating material 45 is molded when compared with a pattern in which a cutout or the like is formed in the outer heat insulating material 45 in accordance with the outer shape of the wooden brick 41. It can be a factor that makes it difficult. Furthermore, it is assumed that it becomes difficult to wipe the gap between the wooden brick 41 and the outer heat insulating material 45 due to dimensional variations of the outer heat insulating material 45, and it becomes difficult to improve the heat insulating function.

  In this respect, as shown in the above embodiment, if the outer heat insulating material 45 is divided into a plurality of pieces and each piece comes into contact with the wooden brick 41, the outer heat insulating material 45 can be easily formed. And the said clearance gap can be wiped off suitably.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows. Incidentally, the configuration of another embodiment described below may be applied individually to the configuration in the above embodiment, or may be applied in combination with each other.

  (A) In the above embodiment, a gap is formed between the outer heat insulating material 45 as the “first heat insulating material” and the inner heat insulating material 65 as the “second heat insulating material”. A gap may be formed between the heat insulating material 65 and the inner wall panel 51. When making such a change, for example, as described above, the outer heat insulating material 45 may be used inside out. Thereby, the inner and outer heat insulating materials 45 and 65 can be brought into close contact with each other, and the gap can be secured.

  Further, the protrusion 48 as the “spacer portion” may be omitted, and the wall 20 may have no spacer portion, and the gap may be secured without depending on the spacer portion. In the case of adopting such a configuration, the inner heat insulating material 65 is not attached to the inner wall panel 51 or the like so as to be movable, but is attached in a state where the inner heat insulating material 65 is movable in the thickness direction of the wall 20. By allowing movement to a position closer to the heat insulating material 45 and movement to a position closer to the inner wall panel 51, the specification of the wall 20 is changed after the fact (for example, after both panel units 30 and 50 are assembled). (Electric wiring, use of soundproofing material, etc., or change of arrangement) are possible.

  (B) It is also possible to form gaps between the inner heat insulating material 65, the outer heat insulating material 45, and the inner wall panel 51, respectively. When such a change is made, a protrusion 48 is provided on the surface facing the indoor side of the outer heat insulating material 45 and a protrusion or the like as a “spacer portion” is provided on the surface facing the indoor side of the inner heat insulating material 65. Further, it is preferable to provide protrusions or the like as “spacer portions” on both plate surfaces of the inner heat insulating material 65.

  If the thickness dimension of the inner heat insulating material is set at least smaller than the gap dimension between the outer heat insulating material and the inner wall panel, the arrangement of the individual inner heat insulating materials can be changed according to the specifications of the wall 20. is there. For example, as shown in the schematic diagram of FIG. 6 (transverse cross-sectional view of the wall 20V), one inner heat insulating material 65V arranged in parallel in the width direction is brought into contact with the outer heat insulating material 45V. (A gap is formed between the inner heat insulating material 65V and the inner wall panel 51), and another inner heat insulating material 65V is brought into contact with the inner wall panel 51 (the inner heat insulating material 65V and the outer heat insulating material 45V. It is also possible to form a gap between them.

  Thus, in the case where the formation position of the gap in the wall 20V is different for each part, the protrusion 69V corresponding to the “spacer portion” is formed not on the outer heat insulating material 45V side but on one plate surface of the inner heat insulating material 65. Good. Thereby, it becomes possible to suitably exhibit the gap maintaining function by changing the direction of the inner heat insulating material 65 according to the specification.

  (C) It is good also as a structure which provides the structure equivalent to the protrusion 48 in the inner side heat insulating material 65, and ensures the clearance gap between both the heat insulating materials 45 and 65 by the protrusion of both heat insulating materials 45 and 65. FIG.

  (D) As shown in the schematic view of FIG. 7 (cross-sectional view of the wall 20W), by placing the inner heat insulating material 65W in a state where the intermediate portion is bent, a gap is formed between the heat insulating materials 45W and 65W. It is also possible to form. That is, the inner heat insulating material 65W formed in a plate shape is arranged so that a flat surface portion 65aW that contacts the outer heat insulating material 45W and a flat surface portion 65bW that contacts the inner wall panel 51 are generated. Is also possible. For example, by setting the width dimension of the inner heat insulating material 65W to be larger than the distance between the vertical frame member 56 and the intermediate frame member 58 in the inner wall frame 55, the bent portion can be easily formed.

  (E) In the above-described embodiment, the inner heat insulating material 65 is brought into contact with the inner wall panel 51 while the thickness T of the inner heat insulating material 65 is set smaller than the distance D between the outer heat insulating material 45 and the inner wall panel 51. By arranging in this manner, a gap was formed between the two heat insulating materials 45, 65 so that the electrical wiring could be arranged, but at least if a gap could be formed between the two heat insulating materials 45, 65 The specific configuration can be changed as follows.

  That is, as shown in the schematic diagram of FIG. 8 (cross-sectional view of the wall 20X), a groove-like recess 71X is formed in a portion of the inner heat insulating material 65X facing the outer heat insulating material 45X, and the outer side of the concave portion 71X is formed. It is also possible to ensure an arrangement route for electric wiring or the like by covering the open portion toward the heat insulating material 45X with the outer heat insulating material 45X. By providing a plurality of the recesses 71X, it is possible to divide the arrangement route of the electric wirings WH1 and WH2 described above. In addition, you may provide the structure corresponded to the recessed part 71X in the outer side heat insulating material 45X side.

  Further, the technical idea shown in the present modification can also be applied to the case where a gap is formed between the inner heat insulating material and the inner wall panel. For example, a groove-shaped recess is formed in the inner heat insulating material on the surface facing the inner wall panel side, and an open portion to the inner wall panel 51 side in the recess is covered with the inner wall panel 51, thereby arranging electric wiring and the like. An installation route can be secured.

  (F) In the above-described embodiment, the protrusion 48 is employed as the “spacer portion”. However, the shape of the spacer portion is arbitrary as long as at least the function of securing the arrangement area of the electric wiring or the like can be exhibited.

  For example, as shown in the schematic diagram of FIG. 9 (a perspective view showing the internal structure of the wall 20Y), the outer heat insulating material 45Y extends in a predetermined direction (for example, the vertical direction) on the surface facing the inner heat insulating material 65 side. The protrusion 49Y may be provided. By partitioning the gap formed between the two heat insulating materials 45Y and 65 by the protrusion 49Y into a plurality of regions, for example, the arrangement route of the electric wiring can be divided into a plurality. That is, it is possible to give the spacer part a function of partitioning the gap into a plurality of regions.

  (G) In the above embodiment, each of the heat insulating materials 45 and 65 is made of rigid urethane foam. However, it is sufficient if at least the plate shape can be maintained, and the heat insulating materials 45 and 65 are made of polystyrene foam, phenol foam, carbonized foam cork. It is also possible to form by.

  Note that the inner heat insulating material as the “second heat insulating material” does not need to be a hard heat insulating material, and may be a soft heat insulating material (for example, glass wool). In the case of embodying such a modification, for example, a bag body in which a polyethylene film having moisture resistance or the like is formed in a bag shape and a fiber-based heat insulating material such as glass wool is filled may be employed.

  (H) In the above embodiment, after the outer wall panel unit 30 is fixed to the beams 11 and 12 as the “casing”, the inner wall panel unit 50 is assembled to the outer wall panel unit 30. The order is not limited to this. For example, after the inner wall panel unit 50 is fixed to the beams 11 and 12, the outer wall panel unit 30 may be assembled to the inner wall panel unit 50. When making such a change, it is desirable to arrange the configuration corresponding to the protrusion 48 not on the outer heat insulating material 45 but on the inner heat insulating material 65.

  Further, the outer wall panel 31, the outer wall frame 35, and the outer heat insulating material 45 are not necessarily unitized, and the inner wall panel 51, the inner wall frame 55, and the inner heat insulating material 65 are not necessarily unitized. That is, the wall 20 can be formed by sequentially assembling the individual components.

  (I) In the above embodiment, the outer heat insulating material 45 is attached to the outer wall panel 31 and the inner heat insulating material 65 is attached to the inner wall panel 51. However, at least between the inner heat insulating material 65 and the outer heat insulating material 45 or the inner wall panel 51. As long as a gap can be formed, the attachment targets of these heat insulating materials 45 and 65 are arbitrary. For example, it is possible to attach the inner heat insulating material 65 to the protrusion 48 and to attach both heat insulating materials 45, 65 to the outer wall panel 31.

  (J) As shown in the above-described embodiment, in the configuration in which the region where the inner heat insulating material 65 is disposed is partitioned by the intermediate frame member 58, the through hole 68 for electric wiring formed in each region is provided. The upper limit of the number of is preferably one. The intermediate frame member 58 can suppress the circulation of air between the two arrangement regions, and can suitably suppress the deterioration of the heat insulating function due to the formation of the through hole 68.

  (K) In the above-described embodiment, the gap formed between the two heat insulating materials 45 and 65 is used as an arrangement area for electric wiring. However, the present invention is not limited to this. For example, the gap can be used as an arrangement area for a sound insulating material such as a sound insulating sheet or a sound insulating plate. Furthermore, it is also possible to utilize the space sandwiched between the heat insulating materials as an arrangement area for water distribution pipes and the like. By utilizing the region surrounded by the heat insulating material as a water distribution route, it is possible to make it difficult to cause inconvenience that water freezes in winter.

  Further, in the configuration in which a gap is formed between the inner wall panel 51 and the inner heat insulating material 65, it is also possible to dispose the sound insulating material or the like in the gap.

  (L) Rather than forming the bulging portion 59 on the inner wall frame 55, the thickness dimension of the wooden bricks is made larger than the thickness dimension of the outer heat insulating material 45, so that the electricity between the intermediate frame materials 38 and 58 is increased. A path for the wiring WH may be secured. Further, by making the thickness of the narrow heat insulating material 45B thinner than the thickness of the wooden brick 41 (wide heat insulating material 45A), it is also possible to secure a path for the electric wiring WH.

  (M) In the above embodiment, an example of application to a unit type building has been described. However, the present invention is also applied to buildings having other structures such as a building constructed by a steel frame construction method and a building constructed by a conventional wooden construction method. The invention can be applied.
