Description

TECHNICAL FIELD The present invention relates to a front construction method for a wooden building and a front structure for a wooden building.

2. Description of the Related Art Conventionally, a wooden framework construction method is known as a front construction method for wooden buildings (see, for example, Patent Document 1).
As shown in FIG. 6, in such a conventional construction method, first, for example, a first pillar 51 is erected on a foundation or foundation stone, and one end of a first horizontal member 61 is passed through a through hole 51a of the first pillar 51. Let In this case, three first horizontal members 61 are provided at intervals in the vertical direction.

Subsequently, by sliding the intermediate post 55 in the horizontal direction, the first horizontal member 61 is passed through the through hole 55 a of the intermediate post 55 . Subsequently, by sliding the second column 52 in the horizontal direction, the other end 61 a of the first horizontal member 61 is passed through the through hole 52 a of the second column 52 .

Subsequently, one end of the third horizontal member 63 is passed through the through hole 51 b of the first column 51 . In this case, three third horizontal members 63 are provided at intervals in the vertical direction.
Subsequently, by sliding the third column 53 in the horizontal direction, the through hole 53b of the third column 53 is made to pass through the other end 63a of the third horizontal member 63 .

Subsequently, by sliding the intermediate post 55 in the horizontal direction, the second horizontal member 62 is passed through the through hole 55 a of the intermediate post 55 .

Subsequently, one end of the fourth horizontal member 64 is passed through the through hole 52 b of the second column 52 . In this case, four fourth horizontal members 64 are provided at intervals in the vertical direction.
When the pillars and horizontal members are assembled one by one in this way, the fourth pillar 54 indicated by the chain double-dashed line in the figure is the last pillar to be assembled. At this time, by sliding the fourth column 54 in the horizontal direction, the other end 62a of the second horizontal member 62 is passed through the through hole 54a of the fourth column 54, and the other end 64a of the fourth horizontal member 64 is inserted. cannot pass through the through hole (not shown) of the fourth column 54 . In other words, it is not possible to pass the horizontal member through the column to be assembled last from two directions perpendicular to each other.

Therefore, in the conventional construction method and construction structure, the other end 64a of the fourth horizontal member 64 is shortened, and the fourth pillar 54 is slightly tilted in the vertical direction so that the other end 64a becomes the fourth pillar. It is slightly inserted into the through hole of 54 .

JP 2016-56647 A
