Japanese Unexamined Patent Publication No. 2001-174527 JP-A-2005-120688

However, since the mounting structure of the exterior material described in the above patent document is only configured to fit the protrusions of the mounting bracket into the mounting groove provided on the back surface of the exterior material, the mounting bracket and the exterior material are combined. There was a problem that the fixing strength was weak.

Further, since the exterior material is fixed so as to be in close contact with the mounting surface of the mounting bracket, the curvature of the exterior material is large and the radius is small. Therefore, for example, there is a design restriction that it cannot be used as a corner portion that requires a large curved surface or as a vertical trim attached to a wall surface.

Therefore, the technical problem to be solved by the present invention is to provide an exterior material and a method of constructing the exterior material, which can increase the mounting strength of the connection with the mounting bracket and enable various designs.

The present invention provides an exterior material having the following configuration in order to solve the above technical problems.

According to the first aspect of the present invention, it is an exterior material that is attached to a building mounting frame via mounting brackets.
The mounting bracket is placed in a direction inclined with respect to the wall surface of the external corner, with a fixing surface which contacts the provided with grooves forming rib provided fixed screw support,
The cover that forms the outer surface when installed,
And a pair of mounting grooves formed by a groove formed ribs extending longitudinally on the back side of the cover portion,
The mounting groove provides a sheathing material, characterized in that the opening size is made smaller than the fixed screwed to the locking nut bis projecting from the mounting bracket.

According to the second aspect of the present invention, the mounting groove provides the exterior material of the first aspect, characterized in that the cut surface at an arbitrary height position is configured to have substantially the same shape.

The present invention also provides the following method of constructing an exterior material. It is a construction method of exterior materials that attaches exterior materials to the building frame via mounting brackets.
Disposed inclined orientation with respect to the wall surface of the external corner, the mounting bracket comprising a fixing surface fixed screws are in contact supporting grooves formed ribs provided, arranged so as to protrude the fixing screws on the outer package side , Screw the locking nut on the fixing screw,
Said pair of longitudinally extending on the back side of the cover portion which forms an outer surface of the outer package is formed by a groove formed ribs, the mounting groove opening size is made smaller than the locking nut, the locking nut After inserting from the vertical direction, the locking nut is screwed to connect the exterior material and the mounting bracket.
It is characterized in that a mounting bracket connected to the exterior material is fixed to the mounting frame.

In the above method, it is preferable that the exterior material is formed by extrusion molding, and the cut surface at an arbitrary height position is formed in substantially the same shape.

According to the present invention, the exterior material attached to the mounting skeleton via the metal fitting can be strongly coupled to each other by engaging the nut provided in the fixing screw protruding from the mounting metal fitting with the mounting groove. Further, since the mounting groove is provided so as to extend in the vertical direction, the mounting bracket can be slid in the vertical direction with respect to the exterior material, and the mounting positions of both can be adjusted with high accuracy.

Further, as the exterior material, since the cut surface at an arbitrary height position is configured to have substantially the same shape, it is possible to easily insert the nut from the end of the mounting groove. For example, such an exterior material. The material can be manufactured by extrusion molding. In the case of extrusion molding, the extrusion direction is usually the so-called longitudinal direction, and the longitudinal direction is the longitudinal direction referred to in the present invention.

Further, since the positions of the mounting bracket and the exterior material can be adjusted to arbitrary positions by the mounting grooves formed by the groove forming ribs, the distance from the mounting skeleton can be arbitrarily adjusted. This makes it possible to design a design having a large curve away from the mounting skeleton, for example, when an exterior material is provided at a corner portion, and various designs can be made.

Further, the exterior material of the present invention is provided at the corner portion of the protruding corner for easy mounting work, and in this configuration, the mounting bracket is provided with a fixing surface in a direction inclined with respect to the wall surface of the protruding corner. By contacting and supporting the groove-forming ribs on the fixed surface, the exterior material can be attached with high strength.
