(Operation and effect of the first embodiment)
Next, the operation and effect of this embodiment will be described.

  Here, the operation and effect of the present embodiment will be described using the proportionality shown in FIGS. In addition, about the same component as this embodiment, the same number is attached | subjected and the description is abbreviate | omitted.

  As shown in FIG. 7, the building unit 100 includes a housing frame 101, an outer wall panel 102 attached to the outer side of the building frame 101, and an inner wall panel 104 attached to the inner side of the outer wall panel 102 via a block 117. It is set as the structure provided with.

  The outer wall panel 102 includes an outer wall member 106 and an outer wall frame 108 fixed to the back side of the outer wall member 106, and the outer wall frame 108 is attached to the ceiling beam 110 and the floor beam 112 of the building unit 100. An outer wall panel 102 is attached to the housing frame 101. The inner wall panel 104 includes an inner wall surface material 114, an inner wall frame 116 fixed to the back surface side of the inner wall surface material 114, and an inner heat insulating material 118 incorporated in the frame of the inner wall frame 116. Is attached to the outer wall frame 108 via the block 117, so that the inner wall panel 104 is attached to the housing frame 101.

  Usually, the attaching operation of the outer wall panel 102 and the inner wall panel 104 to the frame 101 of the building unit 100 is performed in a factory. From the factory to the building site of the unit building constituted by the building unit 100, the vehicle is transported by a vehicle such as a truck 82 as shown in FIG. Specifically, the building unit 100 is transported in a state where the building unit 100 is mounted on the loading platform 84 of the truck 82. For this reason, the size of the building unit 100 needs to be equal to or less than the transportation limit value of the load according to the Road Traffic Law.

  The transport limit value of the loading section under the Road Traffic Law is a width larger than the length dimension when the vehicle traveling direction is the length of the load and the direction perpendicular to the vehicle traveling direction on the horizontal plane is the width of the load. The dimension of is shorter. For this reason, the building unit 100 having a rectangular parallelepiped shape is mounted in a direction in which the girder direction is the longitudinal direction of the loading platform 84 of the truck 82. As a result, compared to the size of the building unit 100 in the girder direction, the size D in the wife direction has no margin for the size limit value of the load in the road traffic law.

  On the other hand, it is desirable for the building unit 100 to increase the size of the building unit 100 as much as possible in order to increase the interior space of the interior. Therefore, the dimension D in the wife direction of the building unit 100 is substantially the same as long as it does not exceed the transportation limit value of the load under the Road Traffic Act in a state where the outer wall panel 102 which is in the factory shipment state is attached to the housing frame 101. ing.

  In order to improve the heat insulation performance of the building unit 100 to which the outer wall panel 102 is attached, it is desirable to provide a heat insulating material on the building outer surface of the ceiling beam 110, the floor beam 112 and the column 120 of the building unit 100. However, as described above, the dimension of the building unit 100 in the wife direction is substantially the same as long as it does not exceed the transport limit value according to the Road Traffic Law. Therefore, when the outer wall panel 102 is provided with a heat insulating material, the dimensions of the building unit 100 in the girder direction and the wife direction increase, and particularly in the case of the wife direction, the dimension exceeds the transport limit value. A heat insulating material cannot be provided between the frame 108. As a result, the heat insulation performance of the building unit 100 cannot be improved.

  On the other hand, as shown in FIG. 4, according to the present invention, the building unit 10 at the time of transportation is placed on one girder side surface 35 of the frame 12 so that the dimension on the wife side is within the transportation limit value. Only the outer wall panel 24 composed of the outer wall material 24, the outer wall frame 22 and the heat insulating material 26 is attached, and the outer wall panel 14 is not attached to the opposite side face 35 of the girder and is transported. The dimensions of the building unit 10 are not more than the transport limit value in a state where the outer wall surface material 24 and the outer wall frame 22 are attached to one girder side surface 35 and the other girder side surface 35 of the frame 12. For this reason, the outside wall panel 14 having the outer wall surface material 24 and the outer wall frame 22 is not attached to the other girder side surface 35, so that there is a margin in size, and the heat insulating material having the same thickness as the margin size. 26 can be attached to one girder side surface 35 of the frame 12 as the outer wall panel 14 together with the outer wall surface material 24 and the outer wall frame 22. Therefore, the heat insulating material 26 can be provided on the building outer surface of the ceiling beam 18, the floor beam 20 and the column 16 without exceeding the transport limit value when the building unit 10 is transported. Further, the outer wall panel 15 transported by another truck 82 or the like is attached to the other girder side surface 35 of the building unit 10 in the building site of the unit building, so that one girder side surface of the building unit 10 in a completed state. Similarly to 35, the heat insulating material 26 can be provided on the outside of the building of the ceiling girder 18, the floor girder 20 and the column 16 on the other girder side surface 35. Of course, not only the girder side surface 35 of the building unit 10 but also the wife side surface 37 whose transportation limit value is relatively loose can be provided with the outer wall panel 14 including the heat insulating material 26 in the same manner as the girder side surface 35. Thereby, a heat insulating material can be provided in the building outer surface 48 of the ceiling large beam 18 and the floor large beam 20 of all the side surfaces of the building unit 10 and the building outer surface 74 of the column 16 in a completed state without exceeding the transport limit value.

  Moreover, since the heat insulating material 26 is provided between the outer wall frame 22 and the outer wall surface material 24, conduction of heat inside and outside the building unit 10 through the frame 12 can be suppressed.

  Furthermore, when the outer wall surface material 24 and the outer wall frame 22 are attached to one girder side surface 35 and the other girder side surface 35 of the building unit 10, the dimension D on the wife side is set to be equal to or less than the transport limit value. Therefore, without attaching the outer wall panel 14 having the outer wall surface material 24 and the outer wall frame 22 to one girder side surface 35, a heat insulating material 26 equivalent to the thickness of the outer wall surface material 24 is applied to the other girder side surface 35.
