Thereby, the 1st horizontal member 31 is attached to the outer wall panel 20A-1 for 1st floors. In this manner, by attaching the first horizontal member 31 to the first floor outer wall panel 20A-1, the position of the first floor outer wall panel 20A-1, particularly in the X direction, can be constrained.

Further, a plurality of bolt insertion holes 31Ba are formed in the flange portion 31B. A central bolt 36 extending upward from the center in the Y direction of the base frame portion 2A of the entry / exit portion 2-1 is passed through the bolt insertion hole 31Ba provided in the central portion of the flange portion 31B. As a result, the first horizontal member 31 is positioned in the X direction and the Y direction.
Then, the connecting member 33 is passed through the bolt insertion hole 31Ba from above, and the lower end of the connecting member 33 and the upper end of the anchor bolt 35 are connected by the connection hardware 63. By carrying out like this, the 1st horizontal member 31, the anchor member 21, and the anchor bolt 35 will be mutually fixed.

<Attaching process of second horizontal member 32>
Next, as shown in FIGS. 10 and 11, the second horizontal member 32 is attached to the upper part 11-1 b of the first floor part 11-1 of the housing 6. The upper part 11-1b of the first floor part 11-1 is closer to the beam 6B than the lower part 11-1a.
Specifically, the second horizontal member 32 is attached by installing the second horizontal member 32 and fastening the bolts to the pillars 6A on both sides of the first floor portion 11-1. Thereby, the 2nd horizontal member 32 is attached to the outer wall panel 20A-1 for 1st floors.

Here, as shown in FIGS. 11 to 13, the second horizontal member 32 is a metal member extending in the Y direction and having an L-shaped cross section.
Specifically, the second horizontal member 32 includes an attachment portion 32A to which the first-floor outer wall panel 20A-1 is attached, and a flange portion 32B that is orthogonal to the attachment portion 32A and extends to the indoor side.

A plurality of bolt fastening holes 32Aa are formed in the mounting portion 32A, and bolts extending from the first floor outer wall panel 20A-1 to the indoor side are passed through the bolt fastening holes 32Aa and fastened by nuts. Thereby, the outer wall panel 20A-1 for 1st floors and the 2nd horizontal member 32 are fixed.
And the width of the vertical joint 41 of the panel unit 40 can be adjusted by adjusting the attachment position of the panel unit 40 with respect to the attachment part 32A.

<Formation process of the rising part 2C of the foundation 2 and the third earth 3C>
Next, as shown in FIG. 13, a mold member 60 is disposed on the base frame portion 2A to form a concrete mold for forming the rising portion 2C. Then, the rising portion 2C is formed by placing concrete in the mold.
As shown in FIG. 14, the rising portion 2 </ b> C is formed to a height that reaches the bottom wall portion 21 </ b> A of the anchor member 21.
Here, after the reinforcing bar 37 is also installed in the installation area 5, concrete is poured to form the third soil 3C.
Thus, the waiting time until the concrete is hardened can be shortened by simultaneously forming the rising portion 2C and the third soil 3C.

<Fixing process of anchor member 21 and rising part 2C of outer wall panel 20A-1 for the first floor>
Next, after the rising portion 2C is cured, the first horizontal member 31 and the second horizontal member 32 are removed. Then, as shown in FIG. 15, the mortar 64 is filled and cured between the anchor member 21 of the first-floor outer wall panel 20 </ b> A- 1 and the rising portion 2 </ b> C, and then the nut 62 is tightened against the anchor bolt 35. And fix. Thereby, as shown in FIG. 16, the anchor member 21 and the rising portion 2C of the first-floor outer wall panel 20A-1 are fixed.

According to the construction method of the building 1 described above, the crane 50 is carried into the foundation forming region 4 that forms the foundation 2 of the building 1, and the installation work of the frame 6 and the outer wall panel 20 is performed using the crane 50. it can. And about the installation area 5 of the crane 50 and the 1st side surface part 11 for carrying out the crane 50, after carrying out the crane 50, the attachment operation | work of 20 A of 1st outer wall panels can be implemented efficiently.
By carrying out like this, even if it is difficult to install the crane 50 on the front road R for a long period of time, the crane 50 can be used efficiently and labor saving of construction can be achieved.
Moreover, when attaching the 1st floor outer wall panel 20A-1 to the 1st floor part 11-1 of the 1st side part 11, the 1st floor outer wall is used by using the 1st horizontal member 31 and the 2nd horizontal member 32. The position of panel 20A-1 can be restrained. Thereby, the rising part 2C of the foundation 2 can be formed in a state where the position of the outer wall panel 20A-1 for the first floor is fixed. Therefore, the workability of construction for fixing the rising portion 2C of the foundation 2 and the first-floor outer wall panel 20A-1 can be improved.
