  Next, an operation procedure for constructing the outer wall 34 by assembling the outer wall panels 50, 60, 70 to the building units 20X, 20Y will be described. Here, the description will focus on the work procedure when the outer wall panel 60 is assembled to the building unit 20X. FIG. 9 is a diagram for explaining the work procedure.

  In the unit manufacturing factory, first, an operation of assembling each outer wall panel 50X to the building unit 20X is performed.

  Next, as shown in FIG. 9A, the work of fixing the vertical members 63 to the ceiling beams 22A and the floor beams 23A of the building unit 20X with bolts 76 and 77 is performed. At this time, the work of assembling the temporary beam 43 to the beam defect 36 is also performed. The temporary beam 43 is assembled by temporarily fixing the connecting plates 43a at both ends thereof to the lower beam 41 and the floor large beam 23A with bolts 75 and 77, respectively. In this case, the connecting plate 43a of the temporary beam 43 is (temporarily) fixed (temporarily) to the floor large beam 23A by the bolt 77 together with the vertical member 63 on the floor large beam 23A side. Specifically, both the members 43a and 63 are temporarily fixed to the floor beam 23A with the connecting plate 43a as the inner side and the vertical member 63 as the outer side.

  Although not shown, the temporary beam 43 is also assembled to the beam defect portion 35 by fixing each connecting plate 43a to the lower beam 41 with a bolt.

  Next, as shown in FIG. 9B, an operation of assembling the frame main body 64 between the vertical member 63 and the base frame 52 of the outer wall panel 50X is performed. In this operation, the vertical frame member 81 of the frame main body 64 is fixed to the vertical member 63 with bolts 86, and the vertical frame member 82 is fixed to the vertical frame member 52 a of the base frame 52 with bolts 88. Thereby, the vertical member 63 and the frame main body 64 are integrated to form the base frame 62, and the base frame 62 is assembled to the building unit 20X. In this fixing operation, the fastening by the bolts 86 and 88 is performed from the inside of the frame main body 64 (laterally).

  On the other hand, for the building unit 20Y side, the operation of assembling the outer wall panels 50Y and 70 to the side surface portion 28 of the unit 20Y is performed. Thereby, the outer wall 33 is constructed | assembled in the said side part 28 of the building unit 20Y.

  Thereafter, each building unit 20X, 20Y is transported to a construction site by a truck or the like. At the construction site, the building units 20X and 20Y are installed side by side at predetermined positions.

  After installing each building unit 20X, 20Y, the work which removes the temporary beam 43 from the building unit 20X first is performed. In this operation, the temporary beam 43 is removed from the lower beam 41 and the large floor beam 23A by removing the bolts 75 and 77, respectively. At this time, on the floor large beam 23A side, after removing the bolt 77, the connecting plate 43a of the temporary beam 43 is slid from between the vertical member 63 and the floor large beam 23A and removed.

  Next, as shown in FIG. 9C, an operation of fixing the outer wall surface member 61 to the base frame 62 assembled to the building unit 20X with screws. Thereby, the outer wall panel 60 is assembled | attached to the building unit 20X, and the outer wall 31 is constructed | assembled by each outer wall panel 50X, 60. And the outer wall 34 is constructed | assembled by the outer walls 31 and 33 of each building unit 20X and 20Y continuing.

  Here, when the outer wall surface (outer surface) is deviated between the adjacent outer wall panels 60 and 70 (specifically, outer wall surface materials 61 and 71) of the building units 20X and 20Y, the deviation is eliminated. Therefore, the work of finely adjusting the position of the outer wall panel 60 (specifically, the position of the end of the panel 60 on the outer wall panel 70 side) in the wall thickness direction is performed (see FIG. 8). In this operation, first, the outer wall surface member 61 of the outer wall panel 60 is removed, and the bolts 76 and 77 that fix the vertical member 63 to each of the large beams 22A and 23A are loosened. In this state, the position of the longitudinal member 63 is finely adjusted in the longitudinal direction of the large beams 22 and 23. In this fine adjustment, for example, the outer surface (surface on the outer wall surface material 61 side) of the web 63a of the vertical member 63 is the outer surface (surface on the outer wall surface material 71 side) of the base frame 72 (vertical frame material 72b) of the outer wall panel 70. The position of the longitudinal member 63 is finely adjusted so as to be located on the same plane as ().

  After the fine adjustment is finished, the bolts 76 and 77 are tightened again to fix the longitudinal member 63 to the large beams 22A and 23A. Thereafter, the outer wall surface member 61 is attached to the base frame 62 again. Thereby, the outer surface of the outer wall panel 60 continues in the same plane as the outer surface of the outer wall panel 70.

  The fine adjustment described above may be performed before the outer wall surface member 61 is fixed to the base frame 62. That is, at the time when each building unit 20X, 20Y is installed, if there is a deviation between the outer surface of the vertical member 63 and the outer surface of the base frame 72 (vertical frame member 72b), at that point A fine adjustment operation may be performed.

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

  In the building unit 20X, a vertical member 63 is provided on the side surface 29 on the side facing the building unit 20Y in a state of being bridged between the ceiling large beam 22A and the floor large beam 23, and the vertical member 63 is bolted to the side surface of each large beam 22A, 23A. 76,77. In this case, unlike the conventional technique (the technique of Patent Document 1) in which the vertical member (reinforcing column) is bolted to the end plate fixed to the notched end of the beam, the fixing position of the vertical member 63 is set to the large beam. Fine adjustment in the longitudinal direction of 22A and 23A becomes possible. In such a configuration, among the outer wall panels 50X and 70 on the building unit 20X side, the base frame 62 of the outer wall panel 60 adjacent to the outer wall panel 70 on the building unit 20Y side is part of the vertical member 63. Constructed including. In this case, the position of the outer wall panel 60 can be finely adjusted in the same direction by finely adjusting the fixing position of the vertical member 63 in the longitudinal direction of the large beams 22A and 23A. Fine adjustment in the thickness direction is possible. Thereby, since the outer surface (outer wall surface) of the outer wall panel 60 can be continued on the same surface as the outer surface (outer wall surface) of the outer wall panel 70, it is suppressed that an external appearance is impaired between these both outer wall panels 60 and 70. can do.

  By the way, the above effect can be obtained by providing the vertical member 63 separately from the base frame 62 and attaching the base frame 62 to the vertical member 63. In that respect, in the above embodiment, the vertical member 63 is configured as a part of the base frame 62, so that the vertical member 63 is provided with a function as a base of the outer wall surface member 61 in addition to the position adjusting function of the outer wall panel 60. can do. Thereby, the multi-function of the vertical member 63 can be achieved.

  Since the vertical members 63 are disposed closer to the building unit 20Y than the ceiling beams 22A and the floor beams 23A, the vertical members 63 can be disposed at positions close to the outer wall panel 70 on the building unit 20Y side. In this case, since the fixing position of the vertical member 63 and thus the position of the outer wall panel 60 can be finely adjusted in the wall thickness direction at a position close to the outer wall panel 70, the outer surface of the outer wall panel 60 faces the outer surface of the outer wall panel 70. It can be made easier to match.

  Since the vertical member 63 is assembled to the building unit 20X so as not to exceed the unit boundary line (docking line) of each building unit 20X, 20Y, the building unit 20X even when the vertical member 63 is assembled to the building unit 20X at the unit manufacturing factory. Can be suitably transported to the construction site.

  The base frame 62 of the outer wall panel 60 includes a vertical member 63 and a frame main body portion 64 disposed between the vertical member 63 and the base frame 52 of the outer wall panel 50X. And the frame main-body part 64 was each fixed to the vertical member 63 and the base frame 52 which were arrange | positioned at the both sides. In this case, the frame main body 64 is arranged between the ceiling large beam 22A and the floor large beam 23A, and the frame main body 64 can be suitably supported.

  Further, since the frame main body portion 64 is arranged to be spaced apart upward from the floor large beam 23A, it is possible to suppress the temporary beam 43 from interfering with the frame main body portion 64 when the temporary beam 43 is removed from the floor large beam 23A at the construction site.

  When one of the two adjacent building units 20X and 20Y is installed so as to protrude from the other building unit 20Y and the alcove 11 is formed in the overhanging portion 13, the back of the alcove 11 in the building unit 20X It is conceivable to provide the outer wall 34 across the side surface and the side surface portion 28 (offset side surface portion) of the building unit 20Y. In that case, since the outer wall panels 60 and 70 of each building unit 20A and 20Y will mutually adjoin, in the said embodiment, the above-mentioned structure using the vertical material 63 was applied to such an outer wall structure. In this case, in such an outer wall structure, it is possible to suppress the appearance from being damaged between the outer wall panels 60 and 70 adjacent to each other.

  (1) In the above embodiment, the vertical members 63 are arranged on the building unit 20Y side (in other words, on the outside of the unit) with respect to the large beams 22A and 23A, and on the outside of the units of the large beams 22A and 23A (webs 22a and 23a) Although fixed to the side, this may be changed. For example, when each of the large beams 22A and 23A is disposed with the webs 22a and 23a facing the inside of the unit, the longitudinal member 63 is disposed inside the unit with respect to the large beams 22A and 23A, and the large beams 22A and 23A are disposed. It is conceivable to fix to the side surface inside the unit. Even in such a case, the fixing position of the longitudinal member 63 with respect to the large beams 22A and 23A can be finely adjusted in the longitudinal direction of the large beams 22A and 23A. Therefore, the position of the outer wall panel 60 can be finely adjusted in the same direction by such fine adjustment. Can do.

  (2) In the above embodiment, the vertical member 63 is configured as a part of the base frame 62, but the vertical member 63 may be provided separately from the base frame 62. In that case, for example, the base frame 62 is formed in a rectangular frame shape, and a vertical member 63 is disposed on the back side of the base frame 62 (on the side opposite to the outer wall surface member 61) and fixed to the side surfaces of the respective large beams 22A and 23A. . Then, the base frame 62 is fixed to the vertical member 63 with a bolt or the like. Also in this case, the position of the outer wall panel 60 can be finely adjusted in the same direction by finely adjusting the fixing position of the vertical member 63 with respect to the respective large beams 22A and 23A in the longitudinal direction of the large beam. Therefore, the outer surface of the outer wall panel 60 can be flush with the outer surface of the outer wall panel 70, and the appearance can be prevented from being damaged between the outer wall panels 60 and 70.

  Moreover, in the said embodiment, although the vertical member 63 and the frame main-body part 64 were assembled | attached to the building unit 20X in the unit manufacturing factory, at least any one of these both members 63 and 64 is attached to the building unit 20X at a construction site. It may be assembled.

  (4) In the above embodiment, the outer wall structure of the present invention is applied to a configuration in which the building unit 20X is set back (retracted) with respect to the building unit 20Y. However, the present invention is not necessarily applied to such a unit configuration. Is not to be done. For example, as shown in FIG. 10, the outer wall structure of the present invention may be applied to a configuration in which two building units 20A and 20B having the same long side length are arranged in parallel. In the example of FIG. 10, an inner garage 105 that can park the vehicle across the building units 20 </ b> A and 20 </ b> B is provided. The inner garage 105 is formed on one side of the building unit 20A, 20B in a direction perpendicular to the unit arrangement direction. The inner garage 105 is partitioned on three sides by partition walls 106 to 108, and a vehicle doorway 109 is formed on one side surface thereof. In this case, the inner garage 105 is opened to the outside through the vehicle entrance / exit 109. In this example, the inner garage 105 corresponds to an outdoor open space. The building unit 20A corresponds to the first unit, and the building unit 20B corresponds to the second unit.

  Of the partition walls 106 to 108, the two partition walls 106 and 107 facing each other across the inner garage 105 are provided across the building units 20A and 20B, and the unit alignment direction (building units 20A and 20B). (Short direction). Moreover, the partition wall 108 is provided in the back | inner side of the inner garage 105 in the building unit 20A, and is extended in the longitudinal direction of building unit 20A, 20B.

  Here, among the partition walls 106 to 108, the partition wall 106 is provided with an outer wall 111 facing the garage 105 on the inner garage 105 side. The outer wall 111 includes a plurality of outer wall panels 112 arranged side by side in the unit arrangement direction, and among these outer wall panels 112, the building unit 20A is provided with an outer wall panel 112A (corresponding to a first outer wall panel). The unit 20B is provided with an outer wall panel 112B (corresponding to a second outer wall panel). Accordingly, even in such a configuration, the outer wall panels 112A and 112B of the building units 20A and 20B are arranged adjacent to each other. Therefore, if the outer wall structure of the present invention is applied to such a configuration, that is, among the outer wall panels 112A, When the present invention is applied to the outer wall panel 112A (corresponding to the adjacent outer wall panel) adjacent to the outer wall panel 112B, it is possible to suppress the appearance from being damaged between the outer wall panels 112A and 112B.

  (5) In the above embodiment, the alcove 11 is formed as an outdoor open space in the building unit 20X. However, an open outdoor space other than the alcove 11 such as a balcony, a veranda, or a terrace may be formed. For example, when a balcony is formed as an outdoor open space, a balcony floor may be provided on the balcony. In that case, since the floor of the balcony is formed by laying floor materials or the like on the floor beams 23 and 25 of the building unit 20X constituting the balcony, the floor beams of the building unit 20X have four sides. 23 will be disposed. Therefore, in such a case, the vertical member 63 is fixed to the floor big beam 23 (corresponding to the lower beam) having no defect.
