Accordingly, the position of the outer wall support member can be adjusted, and the case where the interval between the building frame and the outer wall of the building is different can be dealt with.
Moreover, the position in the axial direction can be adjusted by turning the outer wall support member, and the position can be easily adjusted.
Further, the building outer wall is sandwiched between one outer wall support member and the other outer wall support member, and the tightening force of the nut member is transmitted to the other outer wall support member. Therefore, even if the building outer wall is weak in rigidity and easily deformed by external force The nut member is not deformed (for example, crushed) by the tightening force of the nut member.

As shown in FIG. 1, there is a ventilation space (air layer) 3 between a building housing 1 and a building outer wall 2, and the building outer wall 2 is not in contact with the building housing 1 and is separated. Actually, a plurality of attachment materials such as a trunk edge are provided at intervals in the building housing 1, and the building outer wall 2 is attached over the plurality of attachment materials. Part 3 is formed.
An axial base end portion of a bolt member 10 is attached to the building housing 1, and an axial front end portion of the bolt member 10 is inserted through the hole 4 of the building outer wall 2 and protrudes to the outside, and a nut member is formed on the protruding portion. 20 is screwed.
By tightening the nut member 20, the attachment portion of the structure, for example, the fixture 30 is attached to the surface position of the building outer wall 2 (that is, the outdoor surface).
An outer wall support member 40 is provided in the middle of the bolt member 10 in the axial direction, and the rear surface position of the building outer wall 2 (that is, so as to contact the indoor surface of the building outer wall 2). It is transmitted to the bolt member 10 via the support member 40 and supported.

  Thus, even when the tightening force of the nut member 20 is supported by the bolt member 10 via the outer wall support member 40 and the building outer wall 2 is not in contact with the building housing 1 and is separated, the nut member 20. The structure mounting portion of the building outer wall 2 is not deformed toward the building housing 1 by the tightening force, and the structure mounting portion is not recessed or cracked.
