Description

TECHNICAL FIELD The present invention relates to an auxiliary metal fitting used when attaching wall materials to the structural frame of a building, and a method of attaching wall materials to the structural frame of a building.

2. Description of the Related Art In a building, particularly a residential building, an exterior wall is constructed by fastening an exterior wall material manufactured in a factory to the outside of a structural framework. In addition, the structural frame is the part corresponding to the frame that supports the building structure, and is a concept that is opposed to interior materials and exterior materials. The exterior wall material is a plate-like member made of cement, metal, or the like, and is generally called siding.

It is known to attach a component called a starter fitting to the structural frame prior to fastening the exterior wall material to the structural frame (for example, Patent Literature 1). The starter fitting is a metal component having a substantially L-shaped cross section, and includes a base portion fixed to the structural frame and a bearing portion engaged with the lower end of the outer wall material to support the outer wall material. there is The outer wall material is positioned with respect to the starter fitting by engaging its lower end with a bearing portion of the starter fitting. Therefore, if the starter metal fitting is accurately positioned and attached to the structural skeleton, the exterior wall material can be accurately positioned relative to the structural skeleton. In addition, after the outer wall material is fastened to the structural frame by the starter fitting, it is fixed to the structural frame using nails, screws, or the like.

In the lower horizontal panel 4, the weight of the wall material acts in the out-of-plane direction of the lower horizontal panel 4, whereas in the support arm 20, the weight of the wall material acts in the in-plane direction of the support arm 20. do. Therefore, the support arm 20 is less likely to bend than the lower horizontal surface member 4 . That is, the support arm 20 has higher rigidity than the lower horizontal surface member 4 . Therefore, if the wall material is supported by the auxiliary metal fittings 1E, displacement is less likely to occur than when the wall material is supported by the auxiliary metal fittings 1A, so that the positioning accuracy of the wall material is improved.

Since it is configured in this way, the auxiliary metal fitting 1E is positioned on the base 12 only by attaching the auxiliary metal fitting 1E to the base 12.例文帳に追加Then, the starter metal fitting 15 is positioned with respect to the base 12 simply by bringing the starter metal fitting 15 into contact with the supporting arm 20 of the auxiliary metal fitting 1E. Therefore, it is not necessary to form a reference line for positioning the outer wall material 14 or the starter fitting 15 on the structural skeleton S'.

As described above, according to the above-described embodiment, the reference line for positioning the bearing surface material 13, the outer wall material 14, or the starter fitting 15 with respect to the structural frame S or the structural frame S' It does not need to be formed on the skeleton S'. Therefore, the positioning of the auxiliary fittings 1A, 1B, 1C, 1D, and 1E with respect to the structural frame S or the structural frame S' and the positioning of the load-bearing face material 13 or the outer wall material 14 with respect to the structural frame S or the structural frame S' are facilitated. .

However, the technical scope of the present invention is not limited by the above embodiments. The present invention can be freely applied, modified,
Or it can improve and implement.

The auxiliary metal fittings according to the present invention are not limited to those used in combination with the starter metal fittings. The auxiliary metal fitting according to the present invention may be one in which the lower end of the wall material (bearing surface material 13) is brought into direct contact with the lower horizontal surface material 4, like the auxiliary metal fitting 1C described above.

In the above, an example in which the auxiliary metal fitting is manufactured by bending a thin steel plate has been shown, but the auxiliary metal fitting is not limited to that manufactured by bending. The auxiliary fitting may be manufactured by casting, forging or press working. In the above description, the marking lines 7 are formed by laser processing, but the marking lines 7 may be formed by press processing.

The shape of the starter fitting used in combination with the auxiliary fitting is not limited to those illustrated in FIGS. The shape of the starter fitting is arbitrary. Further, the auxiliary metal fitting according to the present invention may be configured integrally with the starter metal fitting.

In the above description, the base 12 is illustrated as a specific example of the horizontal member, but the horizontal member is not limited to the base 12 . A horizontal member is a structural member that constitutes the structural frame of a building, and it is sufficient if it is a member that spans in the horizontal direction, and is not limited by its name or the mounting position in the structural frame.

In the above, an example in which the base 12, that is, the horizontal member is made of wood is shown, but the horizontal member is not limited to a wooden material. The horizontal members may be composed of, for example, lightweight steel frames. If the horizontal members are made of lightweight steel, the auxiliary metal fittings may be fixed to the horizontal members by adhesion or welding.
