Description

  The present invention relates to an exterior material mounting tool and an exterior material mounting structure for mounting an exterior material on the outer wall of a building such as a general house or an apartment house.

Conventionally, various exterior materials have been used in order to improve the aesthetics such as the outer wall of a building and the breezes. As a method for fastening the exterior material to the outer wall (base), a construction method in which it is directly attached to the base with screws or nails and fastened is generally used. However, with this method, the screws and nail heads, which are fastening materials, are visible from the outside, and the aesthetics of the building are impaired. Therefore, in recent years, the mounting of the exterior material has shifted to a construction method in which the exterior material is attached via the exterior material attachment after the exterior material attachment is attached to the base.
As such an exterior material fixture, a latching portion having elasticity is provided on the exterior material fixture, and the latching portion is elastically deformed by fitting an engagement protrusion of the exterior material to the latching portion. There is known one that presses an exterior material toward the base and fixes the exterior material to the ground (see, for example, Patent Document 1).

However, in the above-described exterior material mounting tool, since the locking portion is elastically deformed and presses and fixes the exterior material, the elastic force between the engagement projection of the exterior material and the locking portion of the exterior material mounting tool If it is weak, the exterior material may fall off accidentally after construction or cause backlash. Further, when the elastic force between the engagement protrusion of the exterior material and the engaging portion of the exterior material attachment tool is increased, a large force is required when attaching the exterior material, and workability is deteriorated. Here, if the locking part is not elastically deformed, there will be no problem that the exterior material will accidentally drop off after construction or a large force will be required when attaching the exterior material. When engaging the engaging projection of the exterior material that is smaller than the size with the engaging portion of the exterior material mounting tool, a gap is generated between the engaging projection of the exterior material and the engaging portion, which causes backlash. There are concerns.
Therefore, the exterior material fixture is engaged with the exterior material to restrict the forward movement of the exterior material, and is engaged with the exterior material and elastically presses the exterior material toward the ground side. An exterior material fixture that is provided with an elastic pressing portion has been proposed (see, for example, Patent Document 2). According to such an exterior material fixture, the exterior material can be attached to the base without rattling.
