Description

  The present invention relates to an eaves joint joint of an inner joint type that is attached to the inside of an eaves to connect the eaves.

  2. Description of the Related Art Conventionally, as an eaves joint of an inner joint type that is attached to the inner side of an eaves and connects the eaves, for example, as shown in FIG. 8, the outer shape substantially matches the inner shape of the eaves a An eaves-joint joint b composed of a thin plate-like member that is bent and bent is known (for example, see Patent Document 1).

  In this case, in order to connect the eaves eaves a with the eaves eaves joint b of the inner joint type, the eaves eaves joint b with the adhesive c applied to the outer peripheral surface is straddled between the abutted eaves eaves a. The engagement protrusion e of the eaves rib joint b is hooked on the rear ear part d of the eaves bowl a and is fitted so as to be pushed in the direction of the arrow s, and the engagement between the front ear part f of the eaves bowl a and the eaves joint b The stop recess g is engaged and attached and connected along the inner peripheral surface of the eaves a.

  By the way, in the conventional eave ridge connection structure, as shown in FIG. 9 (a), when the eave ridge a is attached to the eave hanger k attached to the eave ridge, The rear ear part d is attached to the rear ear holding part i of the eaves hook hanger k in a narrow space, but in the case of the eaves part a provided with the opening h toward the inside, the rear ear part d is When attached to the rear ear holding part i, as shown in FIG. 9 (b), the pressing spring j of the rear ear holding part i of the eaves hook hanger k is inserted into the opening h and locked. Sometimes. For this reason, it is used as it is when it is mistakenly attached to the eaves hanger k, and the eaves a may be detached from the eaves hanger k during use.

  Therefore, as an eaves rod in which the rear ear portion d is reliably engaged with the rear ear holding portion i of the eaves rod suspension k, a locking protrusion bulging rearward or forward toward the upper end portion of the rear side wall of the eaves rod A part formed is used. Since the eaves rod has a structure in which the opening h is not provided in the rear ear portion, it is not caught by the holding spring j of the rear ear holding portion i of the eaves rod suspension k.

  However, in the case of an eaves with the locking projection of the rear ear facing rearward, the upper end of the rear side wall of the eaves joint cannot be locked. Also, in the case of eaves with the locking projection of the rear ear facing forward, even if it can be hooked against the base of the locking projection, the eaves are expanded and the eaves joint is fitted In some cases, the upper end of the rear side wall of the eaves joint is lifted away from the base, and adhesion between the rear side wall of the eaves joint and the rear side wall of the eaves joint may be insufficient.

  As a result, a gap is created between the connected eaves and the eaves joint, so that rainwater flowing in the eaves infiltrates from this gap, and rainwater leaks from the seam of the abutted eaves. There was a problem of falling.

Therefore, in order to prevent the upper end of the rear side wall of the joint body portion of the eaves joint from floating from the rear side wall of the eaves joint, the applicant assigns the rear ear portion of the eave bar and the upper end of the rear side wall of the joint body portion. An application was made for an invention of holding with a joint clip (gripping tool) (see Patent Document 2).
