Accordingly, in such a configuration, the mounting jig is bolted to the framework, so that the mounting jig can be easily attached and detached. Further, since the ALC panel 21 is bolted to the mounting jig while the mounting jig is fixed to the framework, the ALC panel 21 can be easily attached and detached.

<Construction method of unit type building>
Next, the construction method of the above unit type building 1 is demonstrated.
First, the lower-floor building unit 3, the upper-floor building unit 5, and the ALC panel 21 are manufactured at the manufacturing factory. An outer wall panel is fixed to one surface on the long side of the outer peripheral unit 3 </ b> A among the building units 3 and 5. Moreover, the outer wall panel 15 is also fixed to the short side of the building units 3 and 5 as appropriate. At this time, the outer wall panel is bolted to the framework 13 (manufacturing process).
Next, as shown in FIGS. 4 and 8, the ALC panel 21 is temporarily fixed to the inner peripheral unit 3 </ b> B in which the outer wall panel 15 is not fixed to the long side surface of the building units 3 and 5. At this time, as shown in FIGS. 5 and 9, the ALC panels 21A and 21B are arranged outside the framework 13 of the inner peripheral unit 3B, and the upper and lower mounting jigs 31, 32, 35, and 36 are used for bolting. (Temporary fixing step)

Subsequently, each of the building units 3 and 5 is placed on the truck bed and transported to the construction site (transport process). In this transport process, the ALC panel 21 is transported to the construction site integrally with the inner peripheral unit 3B.
At the construction site, first, the lower floor building unit 3 is placed and fixed on the foundation 2 to construct the lower floor portion 4. At this time, as shown in FIG. 2, the two outer peripheral units 3A are separated from the inner peripheral unit 3B to form a separation portion A. Then, as shown in FIG. 3, the ALC panel 21 is removed from the framework 13 of the inner peripheral unit 3 </ b> B, and the ALC panel 21 is installed in the gap of the separating portion A (site construction process).
In this on-site construction process, as shown in FIG. 1, the temporarily fixed ALC panel 21 is disposed in the vicinity of the separating part A. Therefore, the ALC panel 21 can be efficiently moved to the main installation position and permanently fixed.

In addition, the upper floor building unit 5 is placed and fixed above the lower floor portion 4 to construct the upper floor portion 6 and, similarly to the lower floor portion 4, an ALC panel is installed in the gap of the formed separating portion. To do. Then, a roof panel etc. are provided above the upper floor part 6 via a shed frame, the roof part 7 is comprised, and the unit type building 1 is completed.
In this way, the construction of the unit type building 1 provided with the closing panel installed in the separating part A is completed.

In the transporting process described above, the width of the loading platform of the transporting truck of the building units 3 and 5 is the width dimension of one short side of the building units 3 and 5 and the outer wall panel attached to the surface of one long side. The dimension that is combined with the thickness dimension is the maximum. That is, the width dimension is necessary when placing the outer peripheral unit 3A to which the outer wall panel is fixed. For this reason, in the case of the inner peripheral unit 3B, since the outer wall panel is not fixed to the surface on the long side, the width dimension on the short side of the inner peripheral unit 3B is smaller than the width dimension of the loading platform, and the There is room in plane space.
On the other hand, when the separating portion A is formed, the transport amount increases by the amount of the ALC panel 21, so when the building units 3, 5 and the ALC panel 21 are transported separately as in the conventional construction method, The number of times the conveyance truck is conveyed increases.

  In the present embodiment, the ALC panel 21 is temporarily installed as a closing panel on either one of the long side surfaces with respect to the inner peripheral unit 3B where the outer wall panel is not attached to any of the long side surfaces. Transport in a fixed manner. As described above, the ALC panel 21 is temporarily fixed to the side surface on the long side of one of the inner peripheral units by effectively using the planar space during transport in the inner peripheral unit 3B, and the inner peripheral unit 3B and the ALC panel 21 are temporarily fixed. Since these are conveyed together, the number of times of conveyance can be reduced. Therefore, the conveyance efficiency can be improved and the conveyance cost can be reduced. Further, even when the interval dimension L is increased, the number of times of conveyance can be similarly reduced, and the conveyance efficiency can be improved.

  In addition, if the separation part A is formed, the living room space area can be increased without increasing the number of building units 3 and 5 installed, but the installation work of the ALC panel 21 to the separation part A is performed on site. Therefore, there was a demerit that the work of construction increased. On the other hand, in the present embodiment, the temporarily fixed ALC panel 21 is integrally moved at the construction site until the inner peripheral unit 3B is placed at a predetermined position integrally with the temporarily fixed ALC panel 21. The work of moving the ALC panel 21 alone is reduced, and the work load at the construction site can be reduced.

According to this embodiment, the following effects can be achieved.
(1) By temporarily fixing the ALC panel 21 to the skeleton 13 of the inner peripheral unit 3B, the ALC panel 21 and the inner peripheral unit 3B can be simultaneously transported on one track, thereby improving the transport efficiency. be able to.

(2) Since the bolts 24 can be used to temporarily fix the ALC panel 21 and the skeleton 13, it is possible to easily perform the temporary fixing work and the work for releasing the temporary fixing at the construction site. In addition, since the ALC panel 21 is temporarily fixed to the framework 13 via the attachment jigs 31, 32, 35, and 36, the temporary fixing operation can be easily performed.

(3) The ALC panel 21 is removed from the inner peripheral unit 3B provided at a predetermined position at the construction site, and the ALC panel 21 is attached to the clearance of the separating portion A, thereby building units 3, 5 at the construction site. The building units 3 and 5 and the ALC panel 21 can be assembled in order and efficiently without changing the order of the installation work.

[Modification of the present invention]
It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, in the above embodiment, the ALC panel 21 that is a closing panel is temporarily fixed to the long side surface of the building unit. However, the closing panel may be temporarily fixed to the short side surface of the building unit. In this way, not only the inner peripheral unit 3B but also the outer peripheral unit 3A (the building unit in which the surface on the long side constitutes the outer wall surface) with the outer wall panel fixed on the long side is closed. Can be transported efficiently by temporarily fixing the panel.
Further, the same effect can be obtained even if the closing panel is temporarily fixed to a building unit arranged near the building unit to be separated.
The closing panel of the present invention is not limited to the ALC panel 21 as the outer wall material described in the above embodiment, and can also be applied to various panels installed in the separating portion A such as a floor panel or a ceiling panel. .

  The present invention is a detached house, an apartment house, etc., and can be used for a unit type building.
