  As shown in FIG. 3, the one wall panel 1 includes a plate-like interior surface material 11 such as a stone kou board and a vertical frame 12 such as a so-called 2 × 6 material attached to the interior surface material 11. And the plate-like lower ground material 13 attached to the interior surface material 11 via the vertical frames 12,... And the surface of the base surface material 13 opposite to the vertical frames 12,. .., A plate-like exterior surface material 15 attached to the base surface material 13 via the body edges 14,..., An edge of the base surface material 13, and an edge of the exterior surface material 15 An edge material 16 attached between the interior surface material 11 and the base surface material 13 and a heat insulating material 17 such as glass wool filled between the interior surface material 11 and the base surface material 13 and a waterproof sheet affixed on the outdoor side of the base surface material 13 18.

  The base surface material 13 is formed in a plate shape by a particle board or the like, and is attached so as to be substantially parallel to the interior surface material 11 via the vertical frame 12. And the frame | frame which supports the load which acts on the wall panel 1 by the interior surface material 11, the vertical frame 12, ..., and the base surface material 13 is comprised.

  Further, the trunk edge 14 is formed in a thin plate shape having a rectangular cross section with wood or the like, and one side surface is opposite to the surface on which the vertical frames 12,. Attached to the surface with a nail or the like, an exterior surface material 15 is attached to the other side surface with a nail or the like.

  Therefore, a ventilation layer 19 having the same width as the height of the trunk edge 14 is formed between the base surface material 13 and the exterior surface material 15 to ensure air permeability inside the wall panel 1. Although not shown, an air inlet and an air outlet are provided at the upper end and the lower end of the ventilation layer 19.

  Further, the exterior surface material 15 is formed in a plate shape by a wood cement board or the like, and is attached to the side surface of the trunk edge 14 with a nail 53 or the like so as to be substantially parallel to the base surface material 13 through the ventilation layer 19. It has been. In addition, the exterior side of the exterior face material 15 is painted for the sake of beauty. Further, the width of the exterior surface material 15 in the horizontal direction is formed to be narrower than the width of the base surface material 13 described above.

  Further, an end surface 161 (see FIG. 1) of the end edge member 16 facing the building unit 2 is opposed to the outer surface member 15 side toward the base surface member 13 side. Since it is cut so as to spread, it is formed to have a trapezoidal cross section.

  The other wall panel 2 has a configuration substantially similar to that of the wall panel 1 described above, and thus the description thereof is omitted.

  And the joint structure C between the building units of this Embodiment is formed between the wall panel 1 of one building unit 1, and the wall panel 2 of the other building unit 2, as shown in FIG. The gasket 4 is inserted into the end face space 3.

  As shown in FIG. 1, the end surface space 3 is formed between the fixed space 31 that is located closest to the indoor side, the reserved space 33 that is positioned closest to the outdoor side, and the fixed space 31 and the reserved space 33. Adjustment space 32.

  The fixed space 31 is formed between the end surface 131 of the one lower ground material 13 and the end surface 231 of the other lower ground material 23, and is sandwiched between the end surfaces 131 and 231 parallel to each other. The width B1 is constant over the outdoor 62 side.

  Further, the adjustment space 32 is formed between the end surface 161 of one end edge member 16 and the end surface 261 of the other end edge member 26 continuously to the outdoor 62 side of the fixed space 31 described above. And since the cross section of these edge materials 16 and 26 is cut and formed in trapezoid shape, the width | variety B2 becomes wide toward the outdoor 62 side from the indoor 61 side.

  That is, the width B2 of the adjustment space is formed so as to interpolate between the narrow width B1 of the fixed space 31 and the wide width B3 of the reserve space 33 described later. The width B2 increases linearly toward the outdoor 62 side.

  Further, the storage space 33 is formed between the end surface 151 of the one exterior surface material 15 and the end surface 251 of the other exterior surface material 25 continuously to the outdoor 62 side of the adjustment space 32 described above. And since it is pinched | interposed between the end surfaces 151 and 251 parallel to each other, the width B3 is constant from the indoor 61 side to the outdoor 62 side. In addition, the width B <b> 3 of the reserved space 33 is wider than the width B <b> 1 of the fixed space 31 corresponding to the width of the exterior surface material 15 being narrower than the width of the base surface material 13.

  And the gasket 4 used for the joint structure C between the building units of this Embodiment is formed in elongate by resin, such as rubber | gum, as shown in FIG. 4, The axial part 40 used as the whole axis | shaft. And inner deformation fin portions 41 and 41 as deformation fin portions, outer deformation fin portions 42 and 42 as deformation fin portions, and a surface fin portion 43.

  The shaft portion 40 is formed to be thicker than an inner deformation fin portion 41, an outer deformation fin portion 42, and a surface fin portion 43, which will be described later, and transmits the force in the pushing direction when inserted into the end face space 3. It is formed to be able to.

  Further, the inner fin portion 41 is formed in a thin wing shape that protrudes from the tip of the shaft portion 40 to both sides, and is linked to an outer fin portion 42 described later via a linkage portion 44. Further, the width W1 of the inner fin portion 41 is formed wider than the expected maximum width B1 including the installation error of the fixed space 31, and is inclined so as to fall toward the surface fin portion 43 side. ing.

  As shown in FIG. 1, in the installed state, it is inserted into the fixed space 31 and deformed so as to fall down to the surface fin portion 43 side, thereby contacting the end surfaces 131, 231 of the base surface materials 13, 23. Yes. In addition, the end surfaces 161 and 261 of the end edge members 16 and 26 are not easily pulled out by being hooked on the sharp return portions.

  Similarly, the outer fin portion 42 is formed in a thin wing shape protruding from the intermediate portion of the shaft portion 40 on both sides, and is linked to the inner fin portion 41 described above via the linkage portion 44. Further, the width W2 of the outer fin portion 42 is formed wider than the expected maximum width B1 including the installation error of the fixed space 31 described above, and is inclined so as to fall toward the surface fin portion 43 side. ing.

  Further, as shown in FIG. 1, in the installed state, the end faces 131 of the base surface materials 13 and 23 are inserted into the fixed space 31 and the adjustment space 32 and are deformed so as to fall to the surface fin portion 43 side. 231 and the end surfaces 161 and 261 of the edge members 16 and 26 are in contact with each other.

  Here, the width W <b> 2 of the outer fin portion 42 is formed to be narrower than the width W <b> 1 of the inner fin portion 41, and in contact with the adjustment space 32 when the inner fin portion 41 is inserted into the fixed space 31. .

  Further, the surface fin portion 43 is attached to the base portion of the shaft portion 40 in a T-shape, and includes a thick portion 431 near the center and thin portions 432 and 432 at the periphery. Further, the width W3 of the surface fin portion 43 is formed wider than the expected maximum width B1 including the installation error of the fixed space 31 described above.

  Since the thick portion 431 is connected to the thick shaft portion 40 and formed thick, it is easy to transmit an axial force when it is struck when the gasket 4 is inserted, and the surface 431a has a surface 431a. It is easy to be processed.

  And since this surface 431a is formed so that it may have the same design as the exterior surface material 15 and the edge material 16 described above, the end surface space 3 is a groove formed in the exterior surface material 15 when viewed from the front. looks like.

  Further, since the thin portion 432 is formed thinner than the thick portion 431 and is provided at the periphery of the thick portion 431, the thin portion 432 is easily deformed in contact with the adjustment space 32 or the like.

  And in the installed state, as shown in FIG. 1, the thin part 432 was inserted into the adjustment space 32 and deformed so as to fall to the outdoor 62 side, so that the edge members 16 and 26 were cut obliquely. It is in contact with the end surfaces 161 and 261.

  Next, the construction method of the joint structure C between the building units of this Embodiment is demonstrated using FIG.

  First, building units U1 and U2 are manufactured by assembling wall panels 1 and 2 and a floor panel (not shown) in a factory.

  Subsequently, each building unit U1, U2 is mounted on a trailer and transported to the site, and is lifted and placed on a reinforced concrete foundation 91 constructed on the site by a crane or the like and fixed by an anchor bolt or the like. At this time, the position is adjusted so that the building units U1 and U2 do not approach too much by the spacer 51 installed between the wall panels 1 and 2 of the adjacent building units U1 and U2.

  Next, in the end face space 3, the waterproof sheet 18 of one wall panel 1 and the waterproof sheet 28 of the other wall panel 2 are joined together with an adhesive or the like, and the indoor space 61 side (see FIG. 1) of the fixed space 31 (see FIG. 1). 3).

  Then, as shown in FIG. 5A, the gasket 4 is pushed into the end face space 3 from the upper end by the hand 74. Here, the depth to be pushed in is set to such a depth that the surface fin 43 (see FIG. 4) of the gasket 4 is flush with the surfaces of the wall panels 1 and 2. Then, the excess part is cut off by the scissors 72.

  Next, as shown in FIG. 5 (b), the thick strip 713 of the insertion jig 71 is applied to the surface fin portion 43 (see FIG. 4) of the gasket 4 and is struck with a hammer 73, so that the gasket 4 is end space. 3 is inserted.

  Here, as shown in FIG. 6, the insertion jig 71 is made of wood or the like, and includes a main body plate 711 and strips 712 and thick strips 713 protruding on both sides thereof.

  The width t1 of the strip 712 is formed narrower than the width t2 of the thick strip 713, and the height h1 of the strip 712 is formed higher than the height h2 of the thick strip 713.

  Normally, a thick strip 713 with a wide width t2 is inserted against the gasket 4, but when the gasket 4 is shallow and the gasket 4 is not loosely fixed, it is thin with a high height h1. The strip 712 is applied to the gasket 4 and inserted to the back of the end space 3.

  In any case, since the insertion tool 71 can be used to insert the inner fin portion 41 and the outer fin portion 42 to the base surface materials 13 and 23, the edge material 16, 26 can be reliably brought into contact.

  Thus, the construction of the joint structure C between the building units is completed by inserting the gasket 4 into the end face space 3.

  Next, the operation of the joint structure C between the building units of the present embodiment will be described with reference to FIGS.

  In this way, the joint structure C between the building units of the present invention is adjusted such that the end face space 3 gradually increases in width B2 toward the fixed space 31 having the constant width B1 and the outdoor 62 as shown in FIG. The gasket 4 includes an inner deformation fin portion 41, an outer deformation fin portion 42, and a surface fin portion 43 as deformation fin portions having widths W1 and W2 wider than the fixed space 31, and an inner deformation fin portion. 41 and the outer deformation fin part 42 are inserted into the fixed space 31, and the surface fin part 43 is inserted into the adjustment space 32.

  Accordingly, the surface fin portion 43 can contact the adjustment space 32 without being greatly deformed, and the inner deformation fin portion 41 and the outer deformation fin portion 42 as the deformation fin portions are inserted into the fixed space 31 and deformed. Since it can be reliably waterproofed, it is possible to improve waterproofness while providing an excellent aesthetic appearance.

  That is, when the building units U1 and U2 are installed and there are no installation errors and the widths B1, B2, and B3 are as designed, the surface fin portion 43 is adjusted to the adjustment space 32 as shown in FIG. And the end surfaces 161 and 261 of the edge members 16 and 26 can be brought into contact with each other in the vicinity of the boundary position between the storage space 33 and the storage space 33.

  Further, when the building units U1 and U2 are installed and the widths B1, B2 and B3 are narrower than the design values due to installation errors, as shown in FIG. It can deform | transform and can be made to contact | abut to the end surfaces 161 and 261 of the edge materials 16 and 26 in the boundary position vicinity of the adjustment space 32 and the storage space 33. FIG.

  Furthermore, when the building units U1, U2 are installed and the widths B1, B2, B3 are wider than the design values due to installation errors, as shown in FIG. 7 (c), by inserting the gasket 4 deeply, The surface fin portion 43 can be brought into contact with the end surfaces 161 and 261 of the end edge members 16 and 26 at an intermediate position of the adjustment space 32.

  Thus, by adjusting the insertion depth of the gasket 4 in accordance with the widths of the widths B1, B2, and B3 due to installation errors, the surface fin portion 43 can be brought into contact with the inclined adjustment space 32. .

  Moreover, since the inner deformation fin part 41 and the outer deformation fin part 42 as the deformation fin parts are formed so that the widths W1 and W2 (see FIG. 4) are wider than the width B1 of the fixed space 31, an installation error occurs. Also, the end surfaces 131 and 231 of the base surface materials 13 and 23 constituting the fixed space 31 and the end surfaces 161 and 261 of the end edge materials 16 and 26 constituting the adjustment space 32 can be reliably brought into contact with each other.

  Therefore, even when an installation error occurs, the surface fin portion 43, the inner deformation fin portion 41, and the outer deformation fin portion 42 are surely waterproof, thereby blocking rainwater entering from the end face space 3 and waterproofing. Can be increased.

  Moreover, if the surface fin part 43 can be made to contact | abut reliably to the adjustment space 32, even if it sees the end surface space 3 from the front, a clearance gap will be lose | eliminated, and the aesthetics will improve even if a certain installation error arises.

  Furthermore, the end surfaces 161 and 261 of the edge members 16 and 26 are cut obliquely so that the adjustment space 32 is formed to expand toward the outdoor 62 side, so that the insertion depth is slightly adjusted. Since the surface fin portion 43 of the gasket 4 can be brought into contact with the adjustment space 32, the depth from the surfaces 152 and 252 (see FIG. 7) of the exterior face materials 15 and 25 can be kept substantially constant. Thus, if the depth can be kept almost constant regardless of the installation error, the appearance is unified and the aesthetics are improved.

  And since the surface 431a of the thick part 431 of the surface fin part 43 of the gasket 4 of this Embodiment is formed in the same design as the exterior face materials 15 and 25 and the edge materials 16 and 26, on the external appearance A sense of unity is born and aesthetics improve.

  Further, since the reaction force for fixing the gasket 4 is obtained by the elastic reaction force when the inner deformation fin portion 41 and the outer deformation fin portion 42 are deformed, the surface fin portion 43 is not greatly deformed and is adjusted. 32 can be brought into contact with each other. Therefore, the durability of the surface fin portion 43 can be improved.

  In addition, since the surface fin portion 43 is not greatly deformed in this way, even when the same design as the exterior face materials 15 and 25 is applied to the surface 431a of the thick portion 431, the design applied to the surface 431a is deformed. It can be prevented from being damaged.

  Further, the end face space 3 of the present embodiment includes a reserve space 33 having a constant width B3 on the outdoor 62 side of the adjustment space 32, and the surface fin portion 43 has a width W3 substantially the same as the width B3 of the reserve space 33. By being formed, it becomes difficult for rainwater to enter from the side of the surface fin portion 43, and a sense of depth appears in the end face space 3 to improve the aesthetic appearance.

  That is, the surface fin portion 43 has entered the indoor 61 side from the outdoor 62 side at least by the same distance as the thickness of the exterior face materials 15 and 25, so that rainwater wraps around from the side of the thin portion 432 of the surface fin portion 43. It has a structure that prevents intrusion.

  In addition, the surface 431 a of the thick wall portion 431 of the surface fin portion 43 of the gasket 4 has the same design as the exterior face materials 15 and 25 and the edge materials 16 and 26, and is provided with the reserved space 33. Thus, since the end face space 3 looks like a groove provided in the exterior face materials 15 and 25, a high-class feeling is born and the aesthetics are further improved.

  In this case, since the width W3 of the surface fin portion 43 is formed to be substantially the same as the width B3 of the storage space 33 formed by the spacer 51, the width W3 of the surface fin portion 43 can be maximized.

  Further, the fixed space 31 is formed between the end surfaces 131 and 231 of the base surface materials 13 and 23, the reserved space 33 is formed between the end surfaces 151 and 251 of the exterior surface materials 15 and 25, and the adjustment space 32 is the edge material 16. , 26 between the end surfaces 161, 261 cut obliquely, the waterproof structure and the aesthetics can be enhanced with a simple structure without substantially changing the structure of a normal building unit.

  That is, in the wall panel 1, the end face 161 is cut obliquely and the width of the exterior face material 15 is narrowed without changing the configuration of the vertical frame 12 and the base face material 13 at all, thereby reducing the end face. A space 3 can be formed. Therefore, the joint structure C between the building units can be constructed using the production line of the conventional factory as it is.

  And since the gasket 4 is provided with the inner side deformation fin part 41 and the outer side deformation fin part 42 as a some deformation fin part, since rain water can be interrupted | blocked in multiple steps, it can improve waterproofness.

  In addition, the waterproof sheet 18 is affixed on the outdoor 62 side of the base surface material 13, and the waterproof sheet is the end face space 3 on the indoor 61 side from the inner deformation fin part 41 and the outer deformation fin part 42 as the deformation fin part. Are joined together.

  Therefore, after the primary waterproofing by the gasket 4 and the secondary waterproofing by the waterproof sheet 18, even if rainwater enters from the gap of the gasket 4, the infiltrated rainwater can be blocked by the waterproof sheet 18. Can be increased.

  And the unit building S of this invention can be made into the unit building provided with the appearance with a high-class feeling while being excellent in waterproofness by providing the joint structure C between the above-mentioned building units.

  Hereinafter, the unit building S including the joint structure C1 between building units in a form different from that of the above embodiment will be described with reference to FIG.

  The description of the same or equivalent parts as those described in the above embodiment will be given the same reference numerals.

  In the present embodiment, unlike the embodiment described above, a case where the gasket 4 is inserted into the end face space 3 in a state where a step d is generated between the wall panels 1 and 2 will be described.

  First, from the configuration, the joint structure C1 between the building units of the present embodiment is formed in the end face space 3 formed between the wall panel 1 of one building unit 1 and the wall panel 2 of the other building unit 2. A gasket 4 is inserted and configured.

  Then, the surface 152 of the exterior surface material 15 of one wall panel 1 and the surface 252 of the exterior surface material 25 of the other wall panel 2 of this embodiment are different from each other in FIG. As shown in FIG.

  That is, when the building units U1 and U2 are installed, if the widths B1, B2, and B3 are as designed but have a step d, as shown in FIG. The part 43 is brought into contact with the end face 151 of the exterior face material 15, and the other surface fin part 43 is brought into contact with the end faces 161 and 261 of the edge members 16 and 26 in the vicinity of the boundary position between the adjustment space 32 and the storage space 33. .

  Also, when the building units U1 and U2 are installed, if the widths B1, B2 and B3 are narrower than the design value due to installation errors and a step d is generated, as shown in FIG. The surface fin portion 43 is brought into contact with the end surface 151 of the exterior face member 15, and the thin wall portion 432 of the other surface fin portion 43 is deformed so that the edge material 16, in the vicinity of the boundary position between the adjustment space 32 and the storage space 33, 26 are brought into contact with the end surfaces 161 and 261 of the plate.

  Further, when the building units U1 and U2 are installed and the widths B1, B2 and B3 are wider than the design values due to installation errors, a gasket 4 is formed as shown in FIG. Insert deeply so that one surface fin portion 43 does not abut against any member, and the other surface fin portion 43 abuts against the end surfaces 161, 261 of the edge members 16, 26 at an intermediate position of the adjustment space 32. Let

  Thus, even if one surface fin part 43 is in a floating state without contacting any member, the adjustment space 32 is narrowed toward the indoor 61 side, so that a gap can be seen from the front. There is no end.

  In any of the above cases, the inner deformation fin portion 41 and the outer deformation fin portion 42 as the deformation fin portions are inserted into the fixed space 31, and the end surfaces 131, 231 and the edge material of the base surface materials 13, 23 are inserted. 16 and 26 are in contact with the end surfaces 161 and 261.

  Therefore, when the level difference d occurs due to an installation error, the waterproof property is slightly inferior to that of the above-described embodiment, but by waterproofing with the inner deformation fin portion 41 and the outer deformation fin portion 42, It can block rainwater from entering and improve waterproofness.

  Other configurations and operational effects are substantially the same as those in the above-described embodiment, and thus the description thereof is omitted.

  The preferred embodiments and examples of the present invention have been described in detail with reference to the drawings, but the specific configuration is not limited to the embodiments or examples, and does not depart from the gist of the present invention. A degree of design change is included in the present invention.

  For example, in the present embodiment and example, the case where the reserve space 33 is provided in the end surface space 3 has been described, but the present invention is not limited to this, and the reserve space 33 may not be provided.

  Moreover, in this Embodiment and the Example, although the gasket 4 which has two deformation fin parts as a some deformation fin part was demonstrated, it is not limited to this, The gasket which has one deformation fin part Alternatively, a gasket having three or more deformed fins may be used.

  Further, in the present embodiment and example, a fixed space 31 is formed between the end surfaces 131, 231 of the base surface materials 13, 23 facing each other, and a reserved space 33 is formed between the end surfaces 151, 251 of the exterior surface materials 15, 25 facing each other. Although the case where the adjustment space 32 is formed between the end surfaces 161 and 261 that are formed and cut obliquely and face each other has been described, the present invention is not limited to this. Any member on the end face may be provided with a fixed space, a reserved space, or an adjustment space.

  And in this Embodiment and the Example, although the waterproof sheet 18 and 28 was provided and the joint structure C and C1 between the building units joined on the indoor 61 side of the fixed space 31 was demonstrated, it is not limited to this. Alternatively, a joint structure between building units without a waterproof sheet may be used.

  Moreover, although this Embodiment and the Example demonstrated the case where the surface 431a of the thick part 431 of the surface fin part 43 of the gasket 4 has the same design as the exterior surface materials 15 and 25, it is limited to this. Instead, they may have the same saturation and different lightness, or may have an entirely different design and serve as an accent.
