Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0018] FIG. 1 is a perspective view showing a schematic configuration of a movable housing structure 1 according to an embodiment of the present invention, FIG. 2 is a perspective view showing a schematic configuration of a housing structure 2 according to a first embodiment of the present invention of the movable housing structure 1, and FIG. 3 is a perspective view showing a schematic configuration of a movable structure 3 of the movable housing structure 1. Further, FIG. 4 is an exploded perspective view of the housing structure 2. In FIG. 2, the upper part to be described later is shown transparently. As shown in FIG. 1, the movable housing structure 1 makes the housing space formed by the housing structure 2 movable by the movable structure 3. For example, it is used for trailer houses, movable entertainment facilities such as movable karaoke boxes and saunas, movable practice facilities such as movable golf driving ranges, and movable sanitary facilities such as movable baths and toilets, etc. The housing structure 2 is used, for example, to form a housing space according to the use of the movable housing structure 1 such as a living room. Note that the use of the movable housing structure 1 is not limited to the above uses.

[0019] As shown in FIGS. 1, 2, and 4, the housing structure 2 of the movable housing structure 1 includes a bottom 10, an upper part 20 that is a part facing the bottom 10, and a wall part 30 that extends between the bottom 10 and the upper part 20. At least a part of the wall part 30 uses CLT (Cross Laminated Timber), which is an orthotropic integrated board. Hereinafter, the housing structure 2 will be specifically described.

[0020] As shown in FIGS. 1, 2, and 4, the housing structure 2 is used to form a housing space according to the use of the movable housing structure 1 for forming a living room or housing various devices and facilities. For example, the bottom 10 functions as a floor, the upper part 20 functions as a roof, and the wall part 30 functions as an outer wall. The bottom 10, the upper part 20, and the wall part 30 form a space inside. The bottom 10 can be attached to the movable structure 3, and when the bottom 10 is attached to the movable structure 3, the housing structure 2 is attached to the movable structure 3.

[0021] As shown in FIGS. 2 and 4, the bottom 10 extends along a plane and has a floor surface 11 and a grounding surface 12, which are a pair of opposing surfaces in the housing structure 2. The floor surface 11 is the surface facing upward in the movable housing structure 1, and the grounding surface 12 is the surface facing the side (lower side) of the grounding surface of the movable housing structure 1 in the movable housing structure 1. Hereinafter, for the convenience of explanation, in the housing structure 2, the side where the floor surface 11 of the bottom 10 faces is defined as the upper side, and the side where the grounding surface 12 of the bottom 10 faces is defined as the lower side.

[0022] As shown in FIG. 4, the bottom 10 has, for example, a frame 13 and at least one floor panel 14 as a single bottom member. The frame 13 is formed to support the floor panel 14. The bottom 10 has, for example, two floor panels 14. The number of floor panels 14 of the bottom 10 is not limited to two and may be one or three or more. Also, the two floor panels 14 have the same or substantially the same form, but the floor panels 14 may have different forms from each other.

[0023] The floor panel 14 is configured to form a pair of surfaces, a floor surface 14a and a ground surface 14b. The floor surface 14a and the ground surface 14b are opposite each other and, for example, extend along a plane. The floor panel 14 also has an edge surface 14c that extends around its entire circumference between the edge of the floor surface 14a and the edge of the ground surface 14b. The floor panel 14 is, for example, in the shape of a square or approximately square plate, with the floor surface 14a and the ground surface 14b forming a square or approximately square plane, and the edge surface 14c extends to form four elongated surfaces.

[0024] The frame 13 is capable of supporting the floor panel 14 at its bottom 10 such that the floor surface 14a and the ground surface 14b of the floor panel 14 form the floor surface 11 and the ground surface 12, respectively. The frame 13 forms a housing space 13a capable of housing the floor panel 14, as shown in Figure 4, for example, and the edge surface 13b of the frame 13 defining the housing space 13a faces the edge surface 14c of the floor panel 14 housed in the housing space 13a. The frame 13 also has a fixing part 13c that allows the floor panel 14 housed in the housing space 13a to be fixed to the frame 13. The fixing part 13c is, for example, a flange protruding from the edge surface 13b of the frame 13. A fixing mechanism such as a bolt may be used to fix the fixing part 13c to the floor panel 14. Alternatively, the fixing part 13c may be a different fixing mechanism such as a bolt.

[0025] Furthermore, the frame 13 is attachable to the movable structure 3. For example, the lower surface of the frame 13 is provided with engaging parts, such as recesses or holes (not shown), which can engage with corresponding engaging parts of the movable structure 3, and the movable structure 3 can be fixed to the frame 13 via these engaging parts. The engaging parts are, for example, known engaging parts, specifically, for example, a protrusion and a recess that accommodates the protrusion, or a bolt and nut or screw hole.

[0026] The wall portion 30 has, for example, at least one corner portion 31. The corner portion 31 has a pair of corner wall members 32 and corner wall member 33. The corner wall member 32 has a pair of side ends 32a, 32b that are height-direction (vertical direction) ends extending between the upper portion 20 and the bottom portion 10, facing away from each other. Similarly, the corner wall member 33 has a pair of side ends 33a, 33b that are height-direction (vertical direction) ends extending between the upper portion 20 and the bottom portion 10, facing away from each other. In the housing structure 2, the corner wall members 32 and 33 are connected to each other at one of their respective side ends 32a, 32b and side ends 33a, 33b. In the illustrated example, the corner wall members 32 and 33 are connected to each other at side end 32b and side end 33a. In addition, CLT is used for at least a portion of each of the corner wall members 32 and 33.

[0027] The corner wall member 32 is configured to form a pair of surfaces, an inner surface 32c and an outer surface 32d, as shown in Figure 4, for example. The inner surface 32c and the outer surface 32d are opposite each other and, for example, extend along a plane. The side ends 32a and 32b are the ends on the side of the corner wall member 32 in a direction perpendicular to the vertical direction (hereinafter also referred to as the "width direction"), including the side edges 32e and 32f, respectively. The side edges 32e and 32f are edges of the corner wall member 32 that extend in the vertical direction opposite each other. The corner wall member 32 also has an upper edge 32g and a lower edge 32h. The corner wall member 32 is, for example, a rectangular or approximately rectangular plate, with the inner surface 32c and outer surface 32d forming a rectangular or approximately rectangular plane or approximately plane, and the side edges 32e, 32f, upper edge 32g, and lower edge 32h extending to form elongated surfaces.

[0028] Furthermore, the corner wall member 32 is provided with a stepped portion 34 for attaching a beam portion 37, which will be described later, as shown in Figure 4, for example. The stepped portion 34 is formed, for example, at the point where the side edge 32e and the upper edge 32g connect and in the vicinity thereof, and is a portion that forms a step by which a part of the side edge 32e is recessed toward the side edge 32f and a part of the upper edge 32g is recessed toward the lower edge 32h. Specifically, for example, the stepped portion 34 has a stepped surface 34a, which is a surface extending in a direction intersecting the side edge 32e, and a stepped surface 34b, which is a surface extending in a direction intersecting the upper edge 32g. The stepped surface 34a is connected to the side edge 32e at one end and to the stepped surface 34b at the other end. The stepped surface 34b is connected to the upper edge 32g at one end and to the stepped surface 34a at the other end. The stepped surface 34a extends, for example, parallel to or approximately parallel to the upper edge 32g, and the stepped surface 34b extends, for example, parallel to or approximately parallel to the side edge 32e.

[0029] Furthermore, as shown in Figure 4, the corner wall member 32 has two through holes 35a on the lower edge 32h side. The through holes 35a are holes that penetrate the corner wall member 32 between the inner surface 32c and the outer surface 32d. The corner wall member 32 also has two through holes 35b that penetrate from the lower edge 32h to each through hole 35a. The through holes 35b are holes through which bolts 40 for fixing the corner wall member 32 to the bottom 10 are passed, and the through holes 35a form a space that accommodates nuts 43 (see Figure 6) that are fastened to the bolts 40 that protrude into the through holes 35a through the through holes 35b. The bolt 40 has, for example, a support portion 40a that extends along a plane and two bolt portions 40b that protrude from the support portion 40a. The support portion 40a can be fixed to the frame 13 of the bottom 10. The two bolt portions 40b are each insertable into the through holes 35b of the corner wall member 32. Note that the number of through holes 35a and 35b is not limited to two; there may be one or three or more. Similarly, the number of bolt portions 40b of the bolt 40 will correspond to the number of through holes 35a and 35b, and is not limited to two.

[0030] Furthermore, fixing holes 35c are formed in the side end portion 32b of the corner wall member 32, which are recessed holes extending inward from the side edge 32f. The number of fixing holes 35c may be one or more. In the illustrated example, four fixing holes 35c are formed. As will be described later, wedge members 38 for fixing the corner wall member 32 and the corner wall member 33 to each other are press-fitted into the fixing holes 35c.

[0031] The corner wall member 33 has a similar shape to the corner wall member 32, but does not have a stepped portion 34. The vertical length of the corner wall member 33 is the same as or approximately the same as the vertical length of the corner wall member 32. For example, as shown in Figure 4, the corner wall member 33 forms a pair of surfaces, an inner surface 33c and an outer surface 33d. The inner surface 33c and the outer surface 33d are opposite each other and, for example, extend along a plane. The side ends 33a and 33b are the widthwise ends of the corner wall member 33, including the side edges 33e and 33f, respectively. The side edges 33e and 33f are the vertically extending edges of the corner wall member 33 that are opposite each other. The corner wall member 33 also has an upper edge 33g and a lower edge 33h. The corner wall member 33 is, for example, a rectangular or substantially rectangular plate, with the inner surface 33c and outer surface 33d forming a rectangular or substantially rectangular plane, and the side edges 33e, 33f, upper edge 33g, and lower edge 33h extending to form elongated surfaces.

[0032] Furthermore, as shown in Figure 4, the corner wall member 33 has one through hole 36a on the lower edge 33h side. The through hole 36a is a hole that penetrates the corner member 33 between the inner surface 33c and the outer surface 33d. The corner wall member 33 also has one through hole 36b that penetrates from the lower edge 33h to the through hole 36a. The through hole 36b is a hole through which a bolt 41 for fixing the corner wall member 33 to the bottom 10 passes, and the through hole 36a forms a space in which a nut 44 (see Figure 6) that is fastened to the bolt 41 protruding into the through hole 36a passes through the through hole 36b is accommodated. The bolt 41 has, for example, a support portion 41a that extends along a plane and a bolt portion 41b that protrudes from the support portion 41a. The support portion 41a can be fixed to the frame 13 of the bottom 10. The bolt portion 41b is insertable into the through hole 36b of the corner wall member 33. The number of through holes 36a and 36b is not limited to one; there may be two or more. Similarly, the number of bolt portions 41b of the bolt 41 will correspond to the number of through holes 36a and 36b, and is not limited to one.

[0033] Furthermore, a fixing hole 36c is formed in the side end portion 33a of the corner wall member 33, between the inner surface 33c and the outer surface 33d, and penetrates the corner member 33. The fixing hole 36c is positioned in the housing structure 2 to communicate with the fixing hole 35c of the corner wall member 32. The number of fixing holes 36c may be one or more, and the number of fixing holes 36c corresponds to the number of fixing holes 35c of the corner wall member 32. In the illustrated example, four fixing holes 36c are formed. As will be described later, a wedge member 38 for fixing the corner wall member 32 and the corner wall member 33 to each other is press-fitted into the fixing hole 36c.

[0034] Figure 5 shows a fixing structure for fixing corner wall members 32 and 33 to each other. In the housing structure 2, the side edge 32f of corner wall member 32 contacts the inner surface 33c of the side end 33a of corner wall member 33, and a wedge member 38 is press-fitted into the fixing hole 36c of corner wall member 33 and the fixing hole 35c of corner wall member 32, thereby fixing corner wall members 32 and 33 together. The wedge member 38 is, for example, a tapered, substantially columnar or rod-shaped member, and for example, a member having a conical or substantially conical surface. The wedge member 38 is also, for example, made of wood. The fixing hole 36c and fixing hole 35c are formed in a shape that allows the wedge member 38 to be press-fitted. For example, the fixing hole 36c and fixing hole 35c are shaped to correspond to the shape of the corresponding part of the press-fitted wedge member 38. The shape of the wedge member 38 is not limited to the shape described above. In addition, in the housing structure 2, the side edge 33e of the corner wall member 33 may contact the inner surface 32c of the side end 32b of the corner wall member 32, and similarly, the wedge member 38 may be press-fitted to fix the corner wall member 32 and the corner wall member 33 together. In this case, the through hole 35c of the corner wall member 32 is formed in the side edge 33e of the corner wall member 33, and the through hole 36c of the corner wall member 33 is formed in the side end 32b of the corner wall member 32.

[0035] Furthermore, as shown in Figure 5, for example, the wedge members 38 are inserted into the corner wall members 32 and 33 at different angles relative to adjacent wedge members 38. Specifically, for example, the uppermost wedge member 38 is inserted into the corner wall members 32 and 33 at an inclination angle α1 with respect to a direction perpendicular to the outer surface 33d or inner surface 33c of the corner wall member 33, or to a direction perpendicular to the side edge 32f of the corner wall member 32. More specifically, for example, the uppermost wedge member 38 is inserted into the corner wall members 32 and 33 at an inclination in the width direction and vertical direction with respect to a direction perpendicular to the outer surface 33d or inner surface 33c of the corner wall member 33, or to a direction perpendicular to the side edge 32f of the corner wall member 32. Furthermore, the second wedge member 38 from the top, located below the uppermost wedge member 38, is inserted into the corner wall members 32 and 33 at a different inclination angle α2 than the uppermost wedge member 38, in a direction perpendicular to the outer surface 33d or inner surface 33c of the corner wall member 33, or in a direction perpendicular to the side edge 32f of the corner wall member 32. More specifically, for example, the second wedge member 38 from the top is inserted into the corner wall members 32 and 33 at an inclination in the width direction and vertical direction perpendicular to the outer surface 33d or inner surface 33c of the corner wall member 33, or in a direction perpendicular to the side edge 32f of the corner wall member 32. In this way, each wedge member 38 is inserted into the corner wall members 32 and 33, and correspondingly, each fixing hole 35 and fixing hole 36c extends at an inclination perpendicular to the outer surface 33d, inner surface 33c, or side edge 32f, respectively.

[0036] Furthermore, the inclination of the uppermost wedge member 38 in the width direction is on the opposite side to the inclination of the second-to-last wedge member 38 in the width direction. Similarly, the inclination of the uppermost wedge member 38 in the vertical direction is on the opposite side to the inclination of the second-to-last wedge member 38 in the vertical direction. For example, the uppermost wedge member 38 is inclined toward the side end 33b in the width direction and inclined upward in the vertical direction. On the other hand, the second-to-last wedge member 38 is inclined toward the side end 33a in the width direction and inclined downward in the vertical direction. The inclination of the uppermost wedge member 38 may be on the opposite side to the inclination of the second-to-last wedge member 38 in either the width direction or the vertical direction. Also, the inclination of the uppermost wedge member 38 may differ from the inclination of the second-to-last wedge member 38 in either the width direction or the vertical direction. The third wedge member 38 from the top is also inserted into the corner wall members 32 and 33 at a different angle of inclination than the second wedge member 38 from the top. For example, the third wedge member 38 from the top is inserted into the corner wall members 32 and 33 at the same or approximately the same angle of inclination as the uppermost wedge member 38. Similarly, the fourth wedge member 38 from the top is also inserted into the corner wall members 32 and 33 at a different angle of inclination than the third wedge member 38 from the top. For example, the fourth wedge member 38 from the top is inserted into the corner wall members 32 and 33 at the same or approximately the same angle of inclination as the second wedge member 38 from the top.

[0037] As described above, since the wedge members 38 are inserted into the corner wall members 32 and 33 at different angles relative to adjacent wedge members 38, the joint between the corner wall members 32 and 33 by the wedge members 38 is of high joint strength. Adjacent wedge members 38 may be inserted into the corner wall members 32 and 33 facing the same or approximately the same direction. Furthermore, the wedge members 38 are not limited to those that taper as described above. For example, the wedge members 38 may have a constant or approximately constant thickness in the extension direction.

[0038] As shown in Figures 2 and 4, the housing structure 2 has, for example, four corners 31. Specifically, the floor section 10 has four corners 10a, 10b, 10c, and 10d, and the housing structure 2 has corners 31a, 31b, 31c, and 31d that correspond to the corners 10a, 10b, 10c, and 10d of the floor section 10, respectively.

[0039] As shown in Figure 2, a corner section 31a is installed at the corner 10a of the floor section 10, and as shown in Figure 4, the corner section 31a has corner wall members 32 and 33 with the configuration described above. Also, as shown in Figures 2 and 4, a corner section 31c is located at the corner 10c diagonally opposite the corner 10a of the floor section 10. The corner section 31c has the same structure as the corner section 31a. In the housing structure 2, the corner section 31c is rotationally symmetric with respect to the corner section 31a with respect to the axis extending in the vertical direction.

[0040] As shown in Figure 2, a corner section 31b is installed at the corner 10b of the floor section 10, and as shown in Figures 2 and 4, the arrangement of corner wall members 32 and 33 at the corner section 31b is symmetrical with respect to the corner section 31a in terms of the plane extending in the vertical direction. For example, the corner wall member 32 of the corner section 31b is installed in the opposite way to the corner wall member 32 of the corner section 31a, with its inner surface 32c facing the outside of the housing structure 2 and its outer surface 32d facing the inside of the housing structure 2. Also, for example, the corner wall member 33 of the corner section 31b is installed in the opposite way to the corner wall member 33 of the corner section 31a, with its inner surface 33c facing the outside of the housing structure 2 and its outer surface 33d facing the inside of the housing structure 2. However, in this case, if the fixing hole 36c of the corner wall member 33 is tapered, at least the direction in which the fixing hole 36c tapers must be opposite to that of the fixing hole 36c of the corner wall member 33 of the corner 31a. Also, for example, the corner wall member 32 of the corner 31b may be formed to be symmetrical with respect to the corner wall member 32 of the corner 31a with respect to the plane facing the side edge 32e or side edge 32f. Similarly, for example, the corner wall member 33 of the corner 31b may be formed to be symmetrical with respect to the corner wall member 33 of the corner 31a with respect to the plane facing the side edge 33e or side edge 33f. In the housing structure 2 according to this embodiment, the corner wall member 32 of corner 31b is symmetrical with respect to the corner wall member 32 of corner 31a with respect to the plane facing the side edge 32e or side edge 32f, and similarly, the corner wall member 33 of corner 31b is symmetrical with respect to the corner wall member 33 of corner 31a with respect to the plane facing the side edge 33e or side edge 33f. Also, as shown in Figures 2 and 4, a corner 31d is located at the corner 10d diagonally opposite the corner 10b of the floor 10. The corner 31d has the same structure as the corner 31b. In the housing structure 2, the corner 31d is rotationally symmetrical with respect to the corner 31b with respect to the axis extending in the vertical direction.

[0041] As described above, the housing structure 2 has two beam sections 37. One beam section 37 extends between one of the corner wall members 32, 33 at one of the paired corner sections 31a, 31b and one of the corner wall members 32, 33 at one of the other paired corner sections 31c, 31d. The other beam section 37 extends between one of the corner wall members 32, 33 at the other of the paired corner sections 31a, 31b and one of the corner wall members 32, 33 at the other of the other paired corner sections 31c, 31d. For the sake of explanation, corner section 31a and corner section 31b are considered a pair, and corner section 31c and corner section 31d are considered a pair.

[0042] Specifically, as shown in Figures 2 and 4, for example, the beam portion 37 extends between the corner wall member 32 of corner 31a and the corner wall member 32 of corner 31d, and also between the corner wall member 32 of corner 31b and the corner wall member 32 of corner 31c. More specifically, the beam portion 37 extends between the stepped portion 34 of the corner wall member 32 of corner 31a and the stepped portion 34 of the corner wall member 32 of corner 31d, and similarly, the beam portion 37 extends between the stepped portion 34 of the corner wall member 32 of corner 31b and the stepped portion 34 of the corner wall member 32 of corner 31c. For example, each end 37a of the beam portion 37 is in contact with the stepped surface 34a of the stepped portion 34 of the corner wall member 32, and each end 37a of the beam portion 37 is fixed to the stepped surface 34a and the stepped surface 34b, and the beam portion 37 is fixed to the corner wall member 32. The beam portion 37 is such that, for example, in the housing structure 2, the upper edge 37b of the beam portion 37 is flush or nearly flush with the upper edge 32g of the corner wall member 32.

[0043] The upper part 20 functions as a ceiling or roof, as shown in Figures 2 and 4, for example, and has an upper body 21 and an upper body 22. The upper body 21 is configured to form a pair of surfaces, an inner surface 21a and an outer surface 21b, as shown in Figures 2 and 4, for example. The inner surface 21a and the outer surface 21b are opposite each other and, for example, extend along a plane. The upper body 21 also forms an edge surface 21c, which is a surface that extends around the entire circumference between the edge of the inner surface 21a and the edge of the outer surface 21b. The upper body 21 is, for example, a rectangular or approximately rectangular plate, with the inner surface 21a and the outer surface 21b forming a rectangular or approximately rectangular plane or approximately plane, and the edge surface 21c extends to form four elongated surfaces.

[0044] The upper body 22 is configured to form a pair of surfaces, an inner surface 22a and an outer surface 22b, as shown in Figures 2 and 4, for example. The inner surface 22a and the outer surface 22b are opposite each other and, for example, extend along a plane. The upper body 22 also forms an edge surface 22c that extends around its entire circumference between the edge of the inner surface 22a and the edge of the outer surface 22b. The upper body 22 is, for example, a rectangular or substantially rectangular plate, with the inner surface 22a and the outer surface 22b forming a rectangular or substantially rectangular plane, and the edge surface 22c extends to form four elongated surfaces. The upper body 21 and the upper body 22 may be the same material, different materials, or materials that are symmetrical with respect to each other. For example, the upper body 22 is symmetrical with respect to the upper body 21 with respect to the surface opposite one of the edge surfaces 21c of the upper body 21.

[0045] Furthermore, the upper body 21 extends between a pair of corners 31a and 31b in the housing structure 2, and the upper body 22 extends between a pair of corners 31c and 31d in the housing structure 2. Also, for example, in the housing structure 2, the outer edge surface 21c of the upper body 21 facing outwards is flush or nearly flush with the outer surface 32d of the corner wall member 32 of corner 31a, the outer surface 33d of the corner wall member 33 of corner 31a, the outer surface 32d of the corner wall member 32 of corner 31b, and the outer surface 33d of the corner wall member 33 of corner 31b. Similarly, for example, in the housing structure 2, the edge surface 22c of the upper body 22 facing outward is flush with or nearly flush with the outer surface 32d of the corner wall member 32 of the corner 31c, the outer surface 33d of the corner wall member 33 of the corner 31c, the outer surface 32d of the corner wall member 32 of the corner 31d, and the outer surface 33d of the corner wall member 33 of the corner 31d.

[0046] The upper body 21 is made to contact the upper edge 32g of the corner wall member 32 of corner 31a, the upper edge 33g of the corner wall member 33 of corner 31a, the upper edge 32g of the corner wall member 32 of corner 31b, and the upper edge 33g of the corner wall member 33 of corner 31b, thereby being attached to the corner wall members 32 and 33 of corner 31a and corner wall members 32 and 33 of corner 31b. The upper body 22 is made to contact the upper edge 32g of the corner wall member 32 of corner 31c, the upper edge 33g of the corner wall member 33 of corner 31c, the upper edge 32g of the corner wall member 32 of corner 31d, and the upper edge 33g of the corner wall member 33 of corner 31d, thereby being attached to the corner wall members 32 and 33 of corner 31c and corner wall members 32 and 33 of corner 31d. The upper body 21 may be fixed to the corners 31a and 31b in the same manner as the fixing method using the wedge member 38 described above, or it may be fixed by other means. Similarly, the upper body 22 may be fixed to the corners 31c and 31d in the same manner as the fixing method using the wedge member 38 described above, or it may be fixed by other means.

[0047] As described above, at least a portion of the wall section 30 is formed from CLT. In the housing structure 2, for example, the corner wall members 32 and 33 of the corner section 31 are formed from CLT. Specifically, for example, the corner wall members 32 and 33 are formed by cutting and other processing corresponding to the shapes of the corner wall members 32 and 33 onto a CLT panel of a predetermined size. Also, the floor panel 14 of the floor section 10 is formed from CLT. Specifically, for example, the floor panel 14 is formed by cutting and other processing corresponding to the shape of the floor panel 14 onto a CLT panel of a predetermined size. Also, the upper bodies 21 and 22 of the upper section 20 are formed from CLT. Specifically, for example, the upper bodies 21 and 22 are formed by cutting and other processing corresponding to the shapes of the upper bodies 21 and 22 onto a CLT panel of a predetermined size. Similarly, the beam section 37 may also be formed from CLT. Note that the floor panel 14 of the floor section 10 does not have to be formed from CLT. Furthermore, the upper bodies 21 and 22 of the upper part 20 do not necessarily have to be formed from CLT.

[0048] Figure 6 shows a dehumidification structure 39 provided in the corner wall members 32 and 33. The housing structure 2 is provided with a dehumidification structure 39 in order to dehumidify the housing space, make the housing space comfortable, and prevent damage such as decay to the housing structure 2. The dehumidification structure 39 is a space that connects the housing space with the outside of the housing structure 2, and specifically, for example, is a through hole that penetrates the housing structure 2. For example, as shown in Figure 6, the space can be made into a dehumidification structure 39 by creating a space between the through holes 35b and 36b through which the bolt portions 40b and 41b of the bolts 40 and 41 that fix the corner wall members 32 and 33 pass, and the bolt portions 40b and 41b, respectively. The housing space and the outside of the housing structure 2 can be connected through the space between the through holes 35b and 36b and the bolt portions 40b and 41b, respectively.

[0049] The components having the above configuration are assembled to form the housing structure 2. Specifically, the floor panel 14 is housed in the housing space 13a of the frame 13, and the floor panel 14 is fixed to the frame 13 to form the bottom 10. In addition, the corner wall members 32 and 33 are fixed using wedge members 38 to form the corners 31, and the corners 31 are fixed to each corner 10a to 10d of the bottom 10 using bolts 40, 41 and nuts 43, 44. Furthermore, the beam 37 is attached between the stepped portion 34 of the corner wall member 32 at corner 31a and the stepped portion 34 of the corner wall member 32 at corner 31d, and between the stepped portion 34 of the corner wall member 32 at corner 31b and the stepped portion 34 of the corner wall member 32 at corner 31c. This forms the wall 30. Furthermore, the upper body 21 is fixed to the upper edges 32g, 33g of the corner wall members 32, 33 of corner 31a and corner wall members 32, 33 of corner 31b, and the upper body 22 is fixed to the upper edges 32g, 33g of the corner wall members 32, 33 of corner 31c and corner wall members 32, 33 of corner 31d. This forms the upper part 20. The parts are assembled in this way, and the housing structure 2 is assembled. For fixing each part of the housing structure 2, a fixing method similar to the fixing method using the wedge member 38 described above may be used, or other methods may be used.

[0050] As described above, the housing structure 2 uses CLT, which has a lower specific gravity than metal. Therefore, the weight of the housing structure 2 can be reduced compared to conventional metal housing structures. This improves the mobility of the movable housing structure 1 and reduces the energy required to move the movable housing structure 1. In addition, the load on the movable structure 3 can be reduced, which helps prevent malfunctions of the movable structure 3.

[0051] Furthermore, in the housing structure 2, the wall section 30 has a corner section 31, and the corner section 31 has corner wall members 32 and 33 made from CLT, and the corner wall members 32 and 33 are connected at the side ends 32b and 33a. Thus, the corner section 31 is formed by having the corner wall members 32 and 33 made from CLT erected on the bottom section 10, and the corner wall members 32 and 33 fixed so as to intersect each other in the width direction. These corner sections 31 (31a to 31d) are provided at the corners 10a to 10d of the floor section 10, respectively. As a result, the strength of the wall section 30 can be increased, and the strength of the housing structure 2 can be improved compared to the strength of conventional housing structures.

[0052] Furthermore, the containment structure 2 utilizes CLT, which has high strength compared to metal, as well as high heat resistance and heat insulation properties. Therefore, the strength of containment structure 2 can be improved compared to conventional metal containment structures. Additionally, the heat resistance and heat insulation properties of containment structure 2 can be improved compared to conventional metal containment structures.

[0053] As described above, according to the first embodiment of the present invention, the weight of the storage structure 2 can be reduced compared to the weight of a conventional storage structure.

[0054] As described above, the storage structure 2 is used to form a storage space according to the intended use of the movable storage structure 1, such as a living room. Depending on the intended use of the movable storage structure 1, various devices and components are provided in the storage structure 2 to form a storage space corresponding to the intended use of the movable storage structure 1. For example, if the intended use of the movable storage structure 1 is a trailer house, devices and components for forming a floor are attached to the bottom 10, devices and components for forming a roof are attached to the upper 20, and devices and components for forming walls, windows, entrances, etc. are attached to the wall section 30. In addition, devices and components for forming a living room are attached within the storage space enclosed by the floor section 10, the upper section 20, and the wall section 30.

[0055] Next, a description will be given of a second embodiment of the present invention: a housing structure 4.

[0056] The housing structure 4 according to the second embodiment of the present invention differs from the housing structure 2 according to the first embodiment of the present invention described above in the structure of the members formed from CLT. Specifically, in the housing structure 2, the corner wall members 32 and 33 of the corner portion 31 of the wall portion 30 are formed from CLT, but in the housing structure 4, the corner wall members 32 and 33 are formed from a hollow CLT layer 50 using CLT as wood according to the embodiment of the present invention. The housing structure 4 will be described in detail below. Note that components of the housing structure 4 that have the same or similar functions as the housing structure 2 are denoted by the same reference numerals and their descriptions are omitted.

[0057] Figure 7 is a cross-sectional view of the hollow CLT layer 50, and Figure 8 is an exploded perspective view of the hollow CLT layer 50. As shown in Figures 7 and 8, the hollow CLT layer 50 has a layer member 51 and a layer member 52, which are layer members made of a pair of CLT, and a gap-forming member group 53 having at least one gap-forming member 54. In the hollow CLT layer 50 according to this embodiment, a plurality of gap-forming members 54 are provided. In the hollow CLT layer 50, the layer member 51 and the layer member 52 face each other. The gap-forming member 54 of the gap-forming member group 53 is a member that extends along the layer member 51 and the layer member 52, respectively, so as to form a space S between the layer member 51 and the layer member 52 in the hollow CLT layer 50. The hollow CLT layer 50 will be described in detail below.

[0058] The layer member 51 is made of CLT, and is a CLT panel of a predetermined size. The layer member 51 has a pair of faces 51a and 51b, which are opposite to each other and extend in the longitudinal and width directions of the CLT. Faces 51a and 51b each extend along a plane, and are, for example, flat or substantially flat. The thickness of the layer member 51, that is, the thickness of the CLT forming the layer member 51, is thickness T1.

[0059] The layer member 52 is a CLT panel of a predetermined size, having the same or substantially the same shape as the layer member 51. The layer member 52 has a pair of opposing surfaces, surface 52a and surface 52b, which extend in the longitudinal and width directions of the CLT. Surfaces 52a and 52b each extend along a plane, and are, for example, flat or substantially flat. The thickness of the layer member 52, that is, the thickness of the CLT forming the layer member 52, is thickness T2.

[0060] The gap-forming member 54 is, for example, a prismatic member formed to extend along the fiber direction of the CLT, and has a pair of opposing surfaces 54a and 54b. Surfaces 54a and 54b each extend along a plane, and are, for example, planar or substantially planar. Surface 54a is, for example, in contact with surface 51a or surface 51b of layer member 51, and surface 54b is, for example, in contact with surface 52a or surface 52b of layer member 52.

[0061] The gap-forming member group 53 of the hollow CLT body layer 50 specifically includes, for example, multiple types of gap-forming members 54, and as shown in Figure 8, for example, there are three types of gap-forming members 55, 56, and 57 as gap-forming members 54. The gap-forming members 55 are attached to the vertical ends of the layer members 51 and 52 so as to extend along the weak axis direction of the CLT. In other words, the hollow CLT body layer 50 has two gap-forming members 55, and in the corner wall members 32 and 33 made of the intermediate CLT body layer 50, one gap-forming member 55 extends along the upper edges 32g and 33g, and the other gap-forming member 55 extends along the lower edges 32h and 33h. The length L3 of the gap-forming member 55 in the extension direction is the same as or approximately the same as the width W1 of the layer member 51, and also the same as or approximately the same as the width W2 of the layer member 52. As shown in Figure 8, the length L1 of the layer member 51 is the length of the CLT of the layer member 51 (dimension in the strong axis direction), and similarly, the length L2 of the layer member 52 is the length of the CLT of the layer member 52. Also, as shown in Figure 8, the width W1 of the layer member 51 is the width of the CLT of the layer member 51 (dimension in the weak axis direction), and similarly, the width W2 of the layer member 52 is the width of the CLT of the layer member 52.

[0062] The gap-forming members 56 are attached to the widthwise ends of the layer members 51 and 52 and to the middle or approximately middle of this widthwise direction, extending along the strong axis direction of the CLT. In other words, the hollow CLT body layer 50 has three gap-forming members 56, and in the corner wall members 32 and 33 made of the intermediate CLT body layer 50, one gap-forming member 56 extends along the side edges 32e and 33e, one gap-forming member 56 extends along the side edges 32f and 33f, and one gap-forming member 56 extends to the middle or approximately middle of the side edges 32e and 33e and the side edges 32f and 33f, respectively. At both ends, the gap-forming members 56 are in contact with or facing the gap-forming members 55 with a small gap between them, and the length L4 of the gap-forming member 56 in the extending direction is smaller than the length L1 of the layer member 51 and also smaller than the length L2 of the layer member 52.

[0063] The gap-forming members 57 extend parallel to or approximately parallel to the gap-forming members 55 and between two adjacent gap-forming members 56. For example, as shown in Figure 8, the hollow CLT layer 50 has eight gap-forming members 57, with four gap-forming members 57 arranged at equal or approximately equal intervals in the strong axis direction between a gap-forming member 56 extending along the side edges 32e, 33e and a gap-forming member 56 adjacent to it, and four gap-forming members 57 arranged at equal or approximately equal intervals in the strong axis direction between a gap-forming member 56 extending along the side edges 32f, 33f and a gap-forming member 56 adjacent to it. The gap-forming members 57 are in contact with or facing the gap-forming members 56 at both ends with a small space between them.

[0064] As shown in Figures 7 and 8, in the hollow CLT layer 50, layer members 51 and 52 face each other, with either surface 51a or 51b facing either surface 52a or 52b. In the illustrated example, surfaces 51b and 52b face each other. In the hollow CLT layer 50, gap-forming members 54 (55, 56, 57) are arranged side by side between the opposing surfaces 51b and 52b. The surfaces 54a and 54b of each gap-forming member 54 (55, 56, 57) are in contact with the opposing surfaces of the layer members 51 and 52. In the illustrated example, surface 54a is in contact with surface 51b of layer member 51, and surface 54b is in contact with surface 52b of layer member 52. Thus, a space S with a thickness T3 of the gap-forming members 54 (55, 56, 57) is formed between layer member 51 and layer member 52.

[0065] In the hollow CLT layer 50, the gap-forming members 54(55, 56, 57) are fixed to the layer members 51 and 52. For example, the surfaces 54a and 54b of the gap-forming members 54(55, 56, 57) are bonded to the surface 51b of the layer member 51 and the surface 52b of the layer member 52, respectively, thereby fixing the gap-forming members 54(55, 56, 57) to the layer members 51 and 52. For bonding the gap-forming members 54(55, 56, 57), for example, an aqueous polymer isocyanate resin adhesive is used. However, the adhesive used for bonding the gap-forming members 54(55, 56, 57) is not limited to an aqueous polymer isocyanate resin adhesive. The gap-forming members 54(55, 56, 57) may also be fixed to the layer members 51 and 52 by other fixing means.

[0066] The gap-forming members 54 (55, 56, 57) are arranged between the layer members 51 and 52 as described above, but the gap-forming members 54 (55, 56, 57) may be arranged in a different manner than described above. For example, the gap-forming member 55 may extend along the side edges 32e, 33e and side edges 32f, 33f, respectively, and the gap-forming member 56 may extend along the upper edges 32g, 33g, the lower edges 32h, 33h, and the midpoint or approximately midpoint between the upper edges 32g, 33g and the lower edges 32h, 33h, respectively. In addition, in the hollow CLT layer 50, the gap-forming members 54 (55, 56, 57) may be arranged to extend diagonally in the direction of the CLT fibers. Furthermore, in the corner wall members 32 and 33, the gap-forming members 54 may be formed along each end. For example, a gap-forming member 54 may be provided along the stepped surfaces 34a and 34b of the stepped portion 34 of the corner wall member 32.

[0067] As described above, the corner wall members 32 and 33 of the corner 31 are formed from a hollow CLT layer 50. Specifically, the corner wall members 32 and 33 are formed by cutting and other processing a panel of a hollow CLT layer 50 of a predetermined size to correspond to the shapes of the corner wall members 32 and 33. Alternatively, a layer member 51 corresponding to the corner wall members 32 and 33 may be created by cutting and other processing a panel of CLT of a predetermined size to correspond to the shapes of the corner wall members 32 and 33. Similarly, a layer member 52 corresponding to the corner wall members 32 and 33 may be created by cutting and other processing a panel of CLT of a predetermined size to correspond to the shapes of the corner wall members 32 and 33. In addition, gap-forming members 54 (55, 56, 57) corresponding to the corner wall members 32 and 33 may be created, and these may be combined to form a hollow CLT layer 50 corresponding to the shapes of the corner wall members 32 and 33. One of the surfaces 51a and 52a of the hollow CLT layer 50 becomes the inner surface 32c of the corner wall member 32, and the other surface 51a and 52a becomes the outer surface 32d of the corner wall member 32. Similarly, one of the surfaces 51a and 52a of the hollow CLT layer 50 becomes the inner surface 33c of the corner wall member 33, and the other surface 51a and 52a becomes the outer surface 33d of the corner wall member 33.

[0068] In the housing structure 2, the through holes 35a, 35b and fixing holes 35c of the corner wall member 32 formed from the hollow CLT layer 50 may be provided in either the layer member 51 or the layer member 52 of the hollow CLT layer 50, or in both. When the through holes 35a, 35b and fixing holes 35c are provided in both the layer member 51 and the layer member 52 of the hollow CLT layer 50, for example, two sets of bolts 40 and nuts 43 are used in the corner 31. The two bolts 40 may be fixed to the frame 13, or one may be fixed to the floor panel 14.

[0069] Similarly, in the housing structure 2, the through holes 36a, 36b and fixing holes 36c of the corner wall member 33 formed from the hollow CLT layer 50 may be provided in either the layer member 51 or the layer member 52 of the hollow CLT layer 50, or in both. When the through holes 36a, 36b and fixing holes 36c are provided in both the layer member 51 and the layer member 52 of the hollow CLT layer 50, for example, two sets of bolts 41 and nuts are used in the corner 31. The two bolts 41 may be fixed to the frame 13, or one may be fixed to the floor panel 14.

[0070] The hollow CLT layer 50 is made up of layers of CLT, and the corner wall members 32 and 33 formed from the hollow CLT layer 50 can have their strength further improved. Furthermore, the hollow CLT layer 50 is made up of layers of CLT with spaces S interposed between them, and the corner wall members 32 and 33 formed from the hollow CLT layer 50 can have their thermal insulation and heat resistance further improved. In addition, the hollow CLT layer 50 is made up of layers of CLT with spaces S interposed between them, and has high sound insulation and soundproofing performance.

[0071] Furthermore, although the corner wall members 32 and 33 of the housing structure 4 are made of layered CLT, CLT has a lower specific gravity than metal, and the housing structure 4 having corner wall members 32 and 33 formed from hollow CLT layers 50 can also have a reduced weight compared to conventional housing structures made of metal.

[0072] As described above, according to the second embodiment of the present invention, the weight of the housing structure 4 can be reduced compared to the weight of a conventional housing structure, similar to the housing structure 2, the strength of the housing structure 4 can be further improved, and the heat insulation and heat resistance can be further improved. Furthermore, according to the hollow CLT layer 50 (wood) according to the embodiment of the present invention, the weight of the wood can be reduced.

[0073] The movable structure 3 of the movable housing structure 1 is a conventionally known chassis, and as shown in Figure 3 for example, it has a frame 61 on which housing structures 2 and 4 can be mounted and fixed, wheels 62 attached to the frame 61, and a towing part 63 that makes it possible to tow the movable structure 3 attached to the frame 61.

[0074] As shown in Figure 1, the movable housing structure 1 includes a housing structure 2 or a housing structure 4 and a movable structure 3. The housing structure 2 or housing structure 4 is attached to the movable structure 3, making the housing structure 2 or housing structure 4 movable.

[0075] As described above, the weight of the housing structure 2 or housing structure 4 has been reduced. Therefore, the mobility of the movable housing structure 1 can be improved, and the energy required to move the movable housing structure 1 can be reduced. Furthermore, the load on the movable structure 3 can be reduced, thereby preventing malfunctions and other problems with the movable structure 3.

[0076] Although embodiments of the present invention have been described above, the present invention is not limited to the movable housing structure 1, housing structures 2 and 4, movable structure 3, and hollow CLT layer 50 according to the above embodiments of the present invention, but includes all embodiments included in the concept and claims of the present invention. Furthermore, each configuration may be selectively combined as appropriate to achieve at least some of the above-described problems and effects. For example, the shape, material, arrangement, size, etc. of each configuration in the above embodiments may be appropriately changed depending on the specific use of the present invention.

[0077] For example, the vertical dimensions of the corner wall members 32 and 33 of corners 31a and 31b may differ from those of the corner wall members 32 and 33 of corners 31c and 31d. For example, the vertical dimensions of the corner wall members 32 and 33 of corners 31a and 31b may be longer than those of the corner wall members 32 and 33 of corners 31c and 31d. In this case, for example, the upper edge 32g of the corner wall member 32 of corners 31a and 31b is positioned above the upper edge 32g of the corner wall member 32 of corners 31c and 31d, and the upper edge 33g of the corner wall member 33 of corners 31a and 31b is positioned above the upper edge 33 of the corner wall member 33 of corners 31c and 31d. In this case, the upper body 21 is located above the upper body 22.

[0078] Furthermore, for example, the corner wall members 32 and 33 of corners 31a and 31d may have different vertical dimensions than the corner wall members 32 and 33 of corners 31b and 31c. Also, the corner wall members 32 and 33 of corner 31a, corner wall members 32 and 33 of corner 31b, corner wall members 32 and 33 of corner 31c, and corner wall members 32 and 33 of corner 31d may each have different vertical dimensions, and at least two of them may be the same as each other.

[0079] Furthermore, while the hollow CLT layer 50 as wood according to the above-described embodiment of the present invention has two layer members 51 and 52 and a group of gap-forming members 53 provided between these two layer members 51 and 52, the hollow CLT layer as wood according to the present invention may have three or more layer members and two or more groups of gap-forming members. In this case as well, each group of gap-forming members is provided between the layer members that face each other.
