The plurality of building boards 2 in the first stage are arranged so that their lower portions overlap with the front side of the starter 6, and the fixtures 4 are inserted into each of the plurality of insertion holes 20 of each building board 2 and driven into the base 3. , Fixed to the base 3. Here, using two fixtures 4 located in the center in the left-right direction of the four fixtures 4 inserted through each building board 2, two supports 5 are placed in the center in the left-right direction of each building plate 2. Fix it.

Each of the two supports 5 is arranged so that the flat plate portion 500 of the fixing portion 50 is brought into contact with the front surface of each building board 2 and the insertion hole 502 is located in front of the corresponding insertion hole 20 of each building board 2. In this state, the fixture 4 is driven from the front side (outdoor side) to be fixed to the base 3 and each building board 2.

Next, the builder fixes the plurality of building boards 2 in the second stage to the base 3 from above the plurality of building boards 2 in the first stage. The lower part of the second-stage plurality of building boards 2 overlaps the front side of the upper part of the first-stage plurality of building boards 2, and each second-stage building board 2 is relative to each first-stage building board 2. It is arranged so as to be displaced in the left-right direction by half the length of the building board 2. At this time, the left and right ends of the lower ends of each of the second-stage building boards 2 are placed on the support portions 51 of the support tools 5 fixed to the two left and right building boards 2 located below the building boards 2. Arrange as follows. As a result, each of the second-stage building boards 2 is temporarily supported by the support 5 fixed to each of the first-stage building boards 2.

Next, as shown in FIGS. 4A and 5A, the fixture 4 is inserted into each of the plurality of insertion holes 20 of each of the second-stage building boards 2 to fix each building board 2 to the base 3. At this time, also for each of the second-stage building boards 2, the two supports 5 are fixed to the central portion in the left-right direction in the same manner as for each of the first-stage building boards 2. Each of the second-stage building boards 2 is fixed in an inclined posture slightly downward with respect to the front surface of the base 3.

Next, as shown in FIGS. 4B and 5B, the builder fixes the plurality of building boards 2 in the third stage to the base 3 from above the plurality of building boards 2 in the second stage. The lower part of the third-tier building board 2 overlaps the front side of the upper part of the second-tier building board 2, and each third-tier building board 2 becomes each second-tier building board 2. On the other hand, it is arranged so as to be displaced in the left-right direction by half the length of the building board 2. At this time, the left and right ends of the lower ends of each of the third-stage building boards 2 are placed on the support portions 51 of the support tools 5 fixed to the two left and right building boards 2 located below the building boards 2. Arrange as follows. As a result, each of the third-stage building boards 2 is temporarily supported by the support 5 fixed to each of the second-stage building boards 2.

Next, as shown in FIGS. 1 and 5C, the fixture 4 is inserted into each of the plurality of insertion holes 20 of each building board 2 in the third stage, and each building board 2 is fixed to the base 3. At this time, the two supports 5 are fixed to the central portion in the left-right direction of each of the third-stage building boards 2 as well as each of the first-stage and second-stage building boards 2. Each building board 2 in the third stage is fixed in an inclined posture slightly downward with respect to the front surface of the base 3.

By attaching a plurality of stages of building boards 2 from the fourth stage onward to the base 3 in the same manner as the construction method described above, an outer wall having the staggered armored construction structure 1 of the present embodiment is formed.
