Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to an exterior material connecting fitting. More specifically, the present invention relates to an exterior material connecting fitting that can firmly hold and fix an exterior material for construction and that is easy to mount and install.

(Prior Art) Conventionally, exterior materials such as cement-based inorganic boards having excellent properties such as heat insulation and sound insulation have been widely used. These exterior materials are installed from the base side of the outer wall toward the eaves. The so-called horizontal lining method, in which the parts are sequentially spliced together and fixed, has become popular as the most common mounting method.

In this construction method, the exterior material has been attached and fixed directly by nailing, but it is easy for the exterior material to be damaged by nailing and the nail head is exposed on the surface. Since it is not desirable for the construction appearance, dedicated mounting metal fittings have come to be used for mounting and fixing.

As the fitting for connecting and fixing the exterior material, for example, the shape illustrated in FIG. 4 is provided so as to support the weight of the exterior material and not to damage it or to expose the nail head. Known so far.

The connection metal fitting (a) for connecting and fixing the exterior material has a vertical piece (a) for abutting the outer wall surface and a hanging piece (c) which is bent at the upper end and is opposed to the vertical piece (c). A bent piece (d) is formed by extending a part of the portion upward. The hanging piece (c) is provided with an inclined surface, and a nail hole (e) is provided therein. Corresponding to this nail hole (e), a nail hole is also formed in the vertical piece (a).

This connection fitting (a) has an exterior material (f) (ki) connected and fixed, for example, as the structure shown in FIG. That is, first, the upper end portion of the exterior material (F) is inserted and sandwiched between the vertical piece (A) and the hanging piece (C) of the connecting fitting (A), and the vertical piece ( A) is brought into contact with the furring strip (K) of the outer wall surface, and a nail (K) is driven in and fixed from the nail hole (E) provided on the inclined surface of the hanging piece (C). Next, the exterior material (K) is attached from above the connection fitting (A) so that the bent piece (D) of the connection fitting (A) is inserted into the groove of the lower end portion. The exterior material (K) is connected by the elastic force of the bent piece (D).

In this way, by using the connection metal fitting (a), the exterior material (f) and (ki) can be firmly connected and firmly fixed, and the head of the fixing nail (ke) is exposed on the surface. Nor.

(Problems to be solved by the invention) However, in the case of the conventional connecting metal fitting (a) as described above, as illustrated in FIG. 5, the nail (ke) is driven obliquely to the outer wall surface. Therefore, when the driving angle of the nail (ke) deviates from a predetermined angle, the nail head may protrude from the inclined surface of the hanging piece (c), or the top of the nail may bend, etc. There is a drawback that it is not possible to attach g) to the connection fitting (a), or the fixing force of the connection fitting (a) itself to the outer wall surface tends to decrease. Also, in this mounting structure, rattling is likely to occur due to the weight of the exterior material (g).

For this reason, when attaching and installing the exterior material using the conventional connecting metal fittings (a), mounting and fixing the connecting metal fittings (a) becomes a troublesome work, and many of the connecting metal fittings are nailed at a constant angle. It was difficult to fix it, which was an obstacle to improving the construction efficiency. Moreover, there was still a problem with the fixing strength.

The present invention has been made in view of the circumstances as described above, and it is possible to eliminate the drawbacks of the conventional exterior material connecting metal fittings, to facilitate the installation work, and to make the exterior material installation strong. It is an object of the present invention to provide an improved exterior material connecting metal fitting.
