Building material coupling device, coupling structure thereof, and coupling method thereof

A building material coupling structure for coupling two building materials arranged at an interval by a plurality of couplers,

• each of the plurality of couplers including a foundation member arranged on one building material of the two building materials, and a coupling member having a length extending from the foundation member to a side of the other building material and joined to the other building material by a joint,
• wherein at least two couplers are provided on the one building material in a direction orthogonal to a direction of the interval and a thickness direction of the one building material, the foundation member of each coupler is provided with a guide portion configured to guide the coupling member movably in a direction having a component in the thickness direction of the one building material, the foundation members of the at least two couplers are arranged on the one building material while the guide portions of the foundation members of the at least two couplers have different tilting directions or tilting angles with respect to the direction orthogonal to the direction of the interval and the thickness direction of the one building material, before the coupling member arranged for each foundation member is joined to the other building material by the joint, each coupling member is guided by the guide portion to be movable, and since each coupling member is joined to the other building material by the joint, each coupling member cannot be guided by the guide portion and moved.

A building material coupling method for coupling two building materials arranged at an interval by a plurality of couplers,

• each of the plurality of couplers including a foundation member arranged on one building material of the two building materials, and a coupling member having a length extending from the foundation member to a side of the other building material and joined to the other building material by a joint,
• the method comprising:
• a first work step of arranging the foundation members of at least two couplers on the one building material in a direction orthogonal to a direction of the interval and a thickness direction of the one building material, performing an arrangement work for the foundation members to the one building material while causing guide portions provided on the foundation members to guide the coupling members movably in a direction having a component in the thickness direction of the one building material to have different tilting directions or tilting angles with respect to the direction orthogonal to the direction of the interval and the thickness direction of the one building material, and causing the guide portion to guide and movably arrange the coupling member for each foundation member;
• a second work step of adjusting an arrangement position of the coupling member on the foundation member in the direction having the component in the thickness direction of the one building material by causing the guide portion to guide and move each coupling member;
• and
• a third work step of joining each coupling member to the other building material by the joint.
