Description

  The present invention relates to a building corner material that is attached to a corner portion of a wall surface of a building where vertical ribs and horizontal ribs cross at a predetermined crossing angle.

For example, when a wall covering material such as wallpaper, fabric, or synthetic resin cloth is attached to the wall of a building, in order to clean the finish, it is necessary to finish the base surface to a flat surface without unevenness. Therefore, a thin synthetic resin flat plate is integrally connected to the left and right sides in the longitudinal direction of the bent portion formed of a soft synthetic resin material at the corners such as the protruding corner portion and the corner portion of the wall of the building. Corner material is used (see, for example, Patent Documents 1 and 2).
Then, paint or putty (hereinafter collectively referred to as “putty”) is applied to the wall surface and the surface of the corner material so as to form a flat surface without a step with the corner material on the wall surface. A cloth is attached (see, for example, Patent Documents 3 and 4).

FIG. 4A is a perspective view showing an example of a known corner material having transverse ribs and vertical ribs orthogonal to each other, and FIG. 4B is a sectional view of the corner material of FIG. 4A cut in a direction crossing the longitudinal direction. is there.
In this corner material 1, strip-like horizontal ribs 2 and vertical ribs 3 are integrally formed by extrusion molding or the like, and a corner portion 5 where the horizontal ribs 2 and the vertical ribs 3 intersect each other has an edge shape or a corner shape. .
In addition, a large number of through holes 2a and 3a are formed in the horizontal rib 2 and the vertical rib 3 so that the putty applied to the surfaces 2b and 3b of the corner material 1 is favorably held on the corner material 1 and the wall surface. Yes.

The putty is applied by placing an appropriate amount of putty on the plate and applying the putty on the wall surface in one direction, and then finishing to a certain thickness (about 0.3 mm to 0.5 mm). FIG. 5 shows how the putty is applied to the conventional corner material 1 described above.
When the putty 7 on the surface 2b of the lateral rib 2 is extended in one direction toward the corner 5 with the plate 6 (see FIG. 5A), the excess putty 7 is pushed toward the corner 5 side. Then, a part thereof hangs down from the corner 5 to the vertical rib 3 side (see FIG. 5 (b)), and when the heel plate 6 is further escaped from the corner 2 to the side 2b of the lateral rib 2, a highly viscous putty is obtained. 7 extends from the corner portion 5 so as to follow the saddle plate 6 (see FIG. 5C), and causes a phenomenon such as stringing or “hanging” (see FIG. 5D). Therefore, there is a problem that a skilled technique is required to finish the surface with a clean finish.
The present invention has been made to solve such problems, and it is an object of the present invention to provide a building corner material capable of neatly finishing a finished surface by a putty without being an expert.

In order to solve the above-mentioned problems, a building corner material according to the present invention is a building corner material in which vertical ribs and horizontal ribs cross at a predetermined crossing angle, and the surface is formed as an application surface on which paint or putty is applied. The projections projecting from the intersections between the vertical ribs and the horizontal ribs on the extended surfaces of both the vertical ribs and the horizontal ribs are provided.
The protrusions only need to be able to cut the putty by applying a putty and rubbing it while moving the plate in the direction of applying the putty.
In addition, the present invention can be applied to any of the obtuse angle and the acute angle, and may be a right angle. Then, by providing the protrusion on the axis that bisects the crossing angle, the protrusion height of the protrusion from the surface is the same in both the vertical rib and the horizontal rib with a single protrusion. be able to. The protruding height from the extended surface is within a range that does not adversely affect the finished state and appearance, such as a protrusion protruding greatly with respect to the finished surface, and within the range where the putty cutting can be performed well, Specifically, it may be within a range of 0.3 mm to 0.8 mm.
Since the corner material for building of the present invention is configured as described above, it is possible to easily cut the putty simply by rubbing the plate or the like against the protrusion while moving the plate or the like in the direction of applying the putty. It is possible to prevent the stringing of the putty and snare. Therefore, a clean finished surface can be easily obtained even if it is not an expert.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
1A and 1B are schematic views of a corner member according to an embodiment of the present invention. FIG. 1A is an overall perspective view of the corner member partially broken, and FIG. 1B crosses the corner member of FIG. It is sectional drawing cut | disconnected in the direction. In the following description, the same parts and members as those of the conventional corner member 1 shown in FIG.
In the corner member 10 of this embodiment, protrusions 15 are formed at the intersections where the transverse ribs 2 and the longitudinal ribs 3 intersect each other. The protrusion 15 is formed over the entire length of the corner member 10 along the longitudinal direction of the intersection.

The protrusion 15 is formed so as to protrude from the surfaces 2 b and 3 b of both the horizontal rib 2 and the vertical rib 3 by a height h. For example, as shown in FIG. 1B, the cross section having the apex on the axis C that bisects the crossing angle θ (90 degrees in this embodiment) between the horizontal rib 2 and the vertical rib 3 is substantially triangular. If the projection 15 having the shape is formed, the projection 15 protrudes from the surfaces 2 b and 3 b of both the horizontal rib 2 and the vertical rib 3 by the same height h.
The dimension of the height h may adversely affect the finished state and appearance, such as the protrusion 15 protruding greatly from the finished surface after applying putty on the surfaces 2b and 3b or pasting wallpaper. And within the range where the putty can be cut well. The specific dimension depends on the thickness of the putty applied to the surfaces 2b and 3b of the horizontal rib 2 and the vertical rib 3 after finishing, but is preferably slightly larger than the thickness. It may be within the range of 3 mm to 0.8 mm. Further, the top of the protrusion 15 is preferably as narrow as possible in order to enhance the putty cutting effect of the plate, and more preferably has an edge shape as shown.

The present invention is not limited to an L-shaped extruded product in which the transverse rib 2 and the longitudinal rib 3 intersect at a right angle, but the substantially rib-shaped section in which the transverse rib 2 and the longitudinal rib 3 intersect at an acute angle or an obtuse angle other than a right angle. The present invention can also be applied to a mold for an extruded product.
2A and 2B show another embodiment of the corner material of the present invention. FIG. 2A is a sectional view of the corner material when the crossing angle θ is an obtuse angle, and FIG. 2B is a corner when the crossing angle θ is an acute angle. A cross-sectional view of the material is shown. In either case, the apexes of the protrusions 25 and 35 having a substantially triangular cross section are positioned on the axis C that bisects the crossing angle θ.

The operation of the corner member 10 having the above configuration will be described with reference to FIG.
When the putty 7 on the surface 2b of the lateral rib 2 is extended in one direction toward the projection 15 with the gutter plate 6, the surplus putty 7 is pushed toward the projection 15, but the projection 15 moves toward the vertical rib 3 side. Is suppressed (see FIG. 3A). Further, when the collar plate 6 is further escaped from the projection 15 to the outside of the surface 2b of the lateral rib 2 (see FIG. 3 (b)), the putty 7 at the tip of the collar plate 6 is cut by the top of the projection 15, The putty follows the tip of 6 and does not cause stringing or snagging (see FIG. 3C). Therefore, the finished surface can be easily finished cleanly.

Although the preferred embodiments of the present invention have been described, the present invention is not limited to the above description.
For example, although the shape of the protrusion 15 is triangular in the above description, it may be other shapes such as a rectangular shape as long as putty cutting can be performed and stringing and snare can be suppressed.
Further, the corner material is not limited to resin and may be made of metal or paper.
In the above description, the protrusion 15 is provided on the axis that bisects the crossing angle θ. This is based on the premise that the thickness of the putty applied to the horizontal rib 2 and the vertical rib 3 is the same. For example, when the thickness of the putty is different between the horizontal rib 2 and the vertical rib 3, the protrusion height h of the projection 15 is different between the horizontal rib 2 and the vertical rib 3 according to this difference. Therefore, the protrusion 15 may be provided on an axis that appropriately divides the crossing angle θ.

  The present invention can be widely applied to a corner material attached to a corner portion of a wall surface of a building.
