<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, the outer wall panel 15, and the ALC panel 21 are manufactured at the manufacturing factory.
Hereinafter, the lower-floor building unit 3 will be specifically described as an example, but the upper-floor building unit 5 can be manufactured in the same manner.
Outer wall panel 15 is fixed to one surface on the girder side (long side) of outer peripheral unit 3B and one surface on the end side (short side) of outer peripheral unit 3B. Further, the outer wall panel 15 is fixed to one surface on the wife side of the inner peripheral unit 3A. At this time, the outer wall panel is bolted to the framework 13 (manufacturing process).

  Next, as shown in FIG. 2, the ALC panel 21A is temporarily fixed to the inner peripheral unit 3A, and the ALC panel 21B is temporarily fixed to one of the outer peripheral units 3B. At this time, as shown in FIGS. 4 and 5, the ALC panels 21A and 21B are arranged on the outer side of the outer wall panel 15A fixed to the end side of the inner peripheral unit 3A and the outer peripheral unit 3B. Bolts are joined using 32, 33, and 34 (temporary fixing step).

Subsequently, each of the building units 3 and 5 is placed on a loading platform of another truck and transported to the construction site (conveying process). In this transport process, the ALC panels 21A and 21B are transported to the construction site integrally with the inner peripheral unit 3A or the outer 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 3B are separated from the inner peripheral unit 3A to form a separation portion A. Then, as shown in FIG. 2, the ALC panels 21A and 21B are removed from the frame 13 of the inner peripheral unit 3A and the outer peripheral unit 3B, and the ALC panels 21A and 21B are installed in the gaps of the separating part A (site construction process). .
Since the outer peripheral unit 3B and the inner peripheral unit 3A to which the ALC panels 21A and 21B are temporarily fixed are arranged near the separation part A by the site construction fixing, the temporary fixing of the ALC panels 21A and 21B is released. Then, it can be moved in the lateral direction to the next separating part A and fixed.

Further, the upper floor building unit 5 is placed and fixed above the lower floor portion 4 to construct the upper floor portion 6, and in the same manner as the lower floor portion 4, the ALC panel 21 </ b> A, 21B is installed. 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 dimensions of the loading platform of the transporting trucks of the building units 3 and 5 are the width dimension of the one wife side of the building units 3 and 5 and the thickness of the outer wall panel attached to the surface of the one girder side. The dimension that is combined with the length is the maximum. That is, the width dimension is necessary when placing the outer peripheral unit 3B to which the outer wall panel is fixed.
For this reason, in the case of the inner peripheral unit 3A, the outer wall panel and the ALC panel 21 are not fixed to the girder side, so the width dimension on the wife side of the inner peripheral unit 3A becomes smaller than the width dimension of the loading platform, and the There is room in plane space.
In the case of the outer peripheral unit 3B, since the outer wall panel is attached to the surface on one side of the girder, there is no space in the width direction of the loading platform of the transport truck, but there is no space in the length direction of the loading platform. Since there is room, the outer peripheral unit 3B in which the ALC panel 21 is temporarily fixed on the wife side can also be placed on the loading platform.

<Effect of embodiment>
According to the above embodiment, the following effects can be obtained.
(1) The ALC panel 21 is disposed and temporarily fixed on the outside of the outer wall panel 15 of each building unit 3 and 5 provided on the wives side of the frame 13, and the outer wall panel 15 is placed on the truck bed until the construction site. Since it conveys, the building units 3 and 5 and the ALC panel 21 can be efficiently conveyed to a construction site. That is, the space margin in the longitudinal direction of the truck bed can be used effectively.

(2) Since the outer peripheral unit 3B and the inner peripheral unit 3A to which the ALC panel 21 is temporarily fixed are disposed near the separation part A in the site construction fixing, the temporary fixing of the ALC panel 21 is released and immediately adjacent to it. It is possible to move to the separation part A in the horizontal direction and fix the main part.
Therefore, the ALC panel 21 can be simply and efficiently moved to the main installation position (separation part A) and permanently fixed.

(3) Since the ALC panel 21 is temporarily fixed to the outside of the outer wall panel 15 of the building units 3 and 5 via the temporary fixing jig 30, the temporary fixing operation can be easily performed.
In particular, since both the temporary fixing between the temporary fixing jig 30 and the framework 13 and the temporary fixing between the temporary fixing jig 30 and the ALC panel 21 can be performed by bolting, the temporary fixing work and the construction site It is possible to easily perform the work of releasing the temporary fixing.

(4) Since the frame portion 22 of the ALC panel 21 is temporarily fixed in four places with good balance by the four temporary fixing jigs 31, 32, 33, and 34, the building units 3 and 5 are loaded on the truck bed before construction. It is possible to prevent the ALC panel 21 from being detached from the building units 3 and 5 until the installation of the building units 3 and 5 is completed at the site and the temporary fixing of the ALC panel 21 is released.

It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
For example, FIG. 1 shows a case where six building units 3 and 5 are arranged on each floor. However, the unit building 1 of the present invention is not limited to six, and a plurality of building units 3 and 5 are combined. What is necessary is just to be constructed by building at least two of the building units 3 and 5 apart. For example, in the unit type building 1 of FIG. 1, the three building units 3 and 5 arranged in the long-side direction may be formed with the space A between the building units 3 and 5.

In addition, the present invention can be applied even in the case of a unit type building that includes only the outer peripheral unit 3B without arranging the inner peripheral unit 3A.
As a unit type building composed only of the outer peripheral unit 3B, for example, two building units 3, 5 are arranged in the long side direction and the short side direction, and each floor is composed of four building units 3, 5. , A unit type building in which at least two of the building units 3 and 5 are separated from each other.
In this case, since the outer wall panel 15B is fixed to one of the girders of the building units 3 and 5 at the manufacturing factory, the space for temporarily fixing the closing panel 21 to the girders as in the inner peripheral unit 3A. There is no allowance and there is a restriction that the closing panel 21 has to be temporarily fixed on the wife side in order to transport it by truck.
However, even under the restriction, according to the present invention, the closing panel 21 can be temporarily fixed to the end of the outer peripheral unit 3B, so the building unit and the closing panel are efficiently transported to the construction site, And a unit type building can be constructed efficiently.

  Moreover, in the said embodiment, although the ALC panel 21 was temporarily fixed to the outer side of the outer wall panel 15A fixed to the wife side of the building units 3 and 5, the wife side to which the outer wall panel 15A of the building units 3 and 5 is not fixed. Alternatively, the ALC panel 21 may be temporarily fixed.

  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. .

  INDUSTRIAL APPLICABILITY The present invention can be used for a unit type building that is a detached house, an apartment house, and the like and has a separation part.
