Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting exterior corner materials used as a decorative material such as a doorway frame, a vertical wall parting, a veranda parting, a foundation parting, and a pillar of a structure such as a house.

[0002]

2. Description of the Related Art Conventionally, for mounting exterior corner materials,
Generally, screws and nails are used. FIG. 4 shows an example of a mounting structure when the exterior corner material is used as a decorative material for the pillar. In the mounting structure shown in the figure, a spar 52 made of foam plastic or the like is first provided around the steel frame 51 (square pipe).
Is attached with urethane adhesive 55 or the like, and then steel nails 53 are struck and fixed.
Is attached to the pier 52 with a urethane adhesive 56 or the like, and then tapping screws 55 are driven to fix the steel frame 51.

[0003]

However, in this mounting structure, since the corner member 54 is fixed to the steel frame 51 and the splint 52 with the screw 55, it does not look good as it is and the structure vibrates. In the case of doing so, the head of the screw 55 may jump out. In addition, in order to hide the head of the screw 55, each work process such as putty filling, leveling, sealer coating, and top coating is required, and even if repairs are performed by this work, the buried mark is completely erased. Is difficult. Further, the corner material 54 needs to be prepared with holes for screws, and by drilling the holes, the strength of the corner material 54 is reduced, or the corner material 5 is attached to the steel frame 51.
4 may be cracked.

On the other hand, when an inorganic (ceramic-based) corner material 54 such as ceramic is used, the weight of the corner material 54 is considerably heavy, which makes screwing work very difficult. In addition, when fixing with screws, it is difficult to remove it once it is fixed, and it is very important to adjust the inclination with the corner material when the steel frame is not horizontal or vertical (unsteady adjustment). Difficult to do. It is possible to make adjustments by using a spacer between the steel frame and the corner material, but it is extremely complicated to fix the corner material and the spacer at the same time with nails while keeping the position of the corner material straight. It is not practical.

As described above, the conventional mounting structure using screws and nails has various problems such as poor appearance, poor workability, and reduced strength of the corner material. Therefore, a technical problem to be solved by the present invention is to provide a mounting structure which is excellent in workability at the time of mounting a corner material and which does not cause deterioration of appearance and material strength after mounting.

[0006]

In order to solve the above technical problems, in the mounting structure of the exterior corner material according to the present invention, the exterior corner material is mounted on the building structure by using the mounting member. The mounting member includes a first board portion fixed to a first surface forming a corner of a building structure and a second board portion fixed to a second surface of the corner.
A first holding portion having a first holding groove and a second holding portion having a second holding groove formed in an L-shape with the substrate portion and having a second holding groove on the second substrate portion. is doing. Each holding groove extends along the longitudinal direction of the building structure and opens in a direction away from the first surface of the building structure.

The exterior corner material has a first convex portion that fits into the first holding groove and a second convex portion that fits into the second holding groove, and each convex portion is located at the open end of each holding groove. It is formed so as to fit into each holding groove by pushing the corner member from the corresponding position toward the first surface side of the building structure. At least one of the first holding portion and the second holding portion is made of an elastic member, and the holding groove of the holding portion is dimensioned so that the corresponding convex portion is press-fitted.

In the above structure, first, the first board portion is fixed to the first surface and the second board portion is fixed to the second surface, and the attachment member is attached to the building structure. At this time, if the building structure is not horizontal or vertical, a spacer can be fitted between the building structure and the mounting member to adjust the unevenness. When the mounting member is fixed to the building structure, the first convex portion and the second convex portion are then fitted into both holding grooves. In order to strengthen the holding force, it is preferable to apply an adhesive to the first holding groove and the second holding groove. In this case, if the adhesive hardens, the exterior corner material is firmly fixed to the building structure, but immediately after fitting, the exterior corner material can be removed and the work can be redone. . Note that the adhesive may not be used when sufficient holding force can be obtained only by fitting the convex portions and the holding grooves, such as when the exterior corner material is relatively lightweight.

According to the present invention, it is not necessary to use screws or nails for the exterior corner material, and it is sufficient to push the corner material in one direction and fit the both convex portions into both the holding grooves of the mounting member. Installation work is extremely easy. Further, since it is not necessary to form mounting holes in the exterior corner material itself, repair work after mounting is unnecessary, and further, deterioration of strength and generation of cracks in the corner material can be prevented.

Further, when a pair of exterior corner materials is used as a decorative material for a column, the above-mentioned configuration is adopted except that the opening direction of the second holding groove is opposite to the opening direction of the first holding groove. A pair of similarly configured attachment members are attached to a pair of diagonally opposite corners of a building structure having a quadrangular cross section, and the first convex portion of one exterior corner material is used as the first holding groove of the one attachment member. The second convex portion may be fitted to the second holding groove of the other mounting member.

According to this structure, in addition to the above-described effects of preventing deterioration of appearance, improving workability, and preventing deterioration of strength of the corner material, the positions of the end portions of both corner materials to be combined are each one. Since it is regulated by the mounting member, it is possible to prevent the displacement of both ends of each corner member.
