Description

[Detailed description of the invention] The present invention relates to a connection structure for a wall corner part, and more specifically, a vertical corner member 1 made of an inorganic material and having a substantially L-shaped cross section has a deep-spread shape on both vertical surfaces 2 on the inside corner side. A longitudinal groove 3 is formed, and a plurality of elastic connecting pieces 5 are cut and raised in the longitudinal direction on both sides of an L-shaped metal fitting 4 made of a metal plate, and a free end portion of the elastic connecting piece 5 is formed. A fitting part 6 curved in a substantially semicircular arc shape is formed in the vertical direction, and the fitting part 6 of each of the plurality of cut and raised elastic connection pieces 5 is shifted in the vertical direction, and the fitting part 6 adjacent to the fitting part 6 in the vertical direction is shifted. Different insertion directions in the horizontal direction into the vertical groove 3,
The fitting part 6 is inserted into the vertical groove 3 to attach the L-shaped fitting 4 to the inside corner of the vertical corner member 1, and the exterior wall 7 that is butted against the side edge of the vertical corner member 1 is connected to the L-shaped fitting 4. This relates to a connection structure of a wall corner portion connected by a tool 8.

In the conventional wall corner connection structure, as shown in FIGS. 1 to 3, a cut-and-raised piece 4a' formed on one side of the mounting piece 4' is fitted by biting into the corner member 1'. The mounting hole 10' formed on the other side of the mounting piece 4' was used to connect the mounting piece 4' to the exterior wall 7' with a connecting tool 8' such as a screw. However, in such a configuration, there is a difference in the thickness of the corner member 1' and the thickness of the exterior wall 7', and a step is created between the inner surface of the corner member 1' and the inner surface of the exterior wall 7'. If this occurs, that is, if the exterior wall 7' is thin as shown in Figure 4a, use a screw-like connector 8' to bring the mounting piece 4' into tight contact with the exterior wall 7'. If this is done, there is a risk that the cut-and-raised piece 4a' of the mounting piece 4' may come off from the corner member 1', and if the exterior wall 7' is thick as shown in FIG. 4b, the mounting piece 4' There was also a risk that the cut-and-raised piece 4a' would come off due to being pushed by the exterior wall 7'. Furthermore, in the conventional example, the mounting piece 4' was divided into left and right parts with respect to the L-shaped corner member 1', and there was a problem that the workability was low. By the way, if the corner member 1' is made of an inorganic material and it is difficult to install it because it bites into the corner member 1', it is necessary to drill a hole for mounting in the corner member 1' made of an inorganic material in advance or use adhesive to install it. There was a problem that the workability was low.

The present invention was developed in view of these problems, and its purpose is to provide a connection structure for wall corner members that is easy to construct and difficult to separate even when there is a difference in thickness. be.

Embodiments of the present invention will be described in detail below with reference to the drawings.

A vertical corner member 1 is made of an inorganic material and has a substantially L-shaped cross section. A central groove 9 is formed at the center of the inside corner of the vertical corner member 1 over the entire length. Furthermore, vertical grooves 3 are formed in both vertical surfaces 2 on the inside corner side of the vertical corner member 1, extending over the entire length. 4 is an L-shaped metal fitting, which is made by bending a metal plate into an L-shape. Both sides of the L-shaped fitting 4 are cut and raised to form elastic connection pieces 5. A fitting portion 6 curved into a substantially semicircular arc shape is formed at the free end of the cut and raised elastic connection piece 5 . The fitting portion 6 is curved so as to be substantially orthogonal to the cut and raised elastic connection piece 5. The cut and raised elastic connection piece 5 is also formed at the center of the corner of the vertical corner member 1. A plurality of such cut and raised elastic connection pieces 5 are formed vertically apart from each other at vertical intervals. Then, a plurality of cut and raised connection pieces 5
The vertical positions of the respective fitting parts 6 are shifted, and the fitting directions in the horizontal direction (groove circumferential direction) of the fitting parts 6 adjacent to each other in the vertical direction into the vertical groove 3 are made different.

As shown in FIG. 8, the L-shaped fitting 4 is attached to the inside corner of the vertical corner member 1 by inserting the fitting part 6 into the vertical groove 3, and is made of the same material and finished with the same material as the vertical corner member 1. The exterior wall 7 that has been made is butted against the vertical corner member 1, and a connector 8 such as a screw inserted into the mounting hole 10 of the L-shaped bracket 4 is attached to the exterior wall 7, and the exterior wall 7 is attached to the L-shaped bracket 4. It is connected to the vertical corner member 1 via. In such a case, in the vertical groove 3 and the central groove 9. The fitting portion 6 is out of position in the circumferential direction of the groove, and does not easily come out.

In summary, the present invention forms deep and widening vertical grooves on both vertical surfaces of the inside corner of a vertical corner member made of an inorganic material and has an approximately L-shaped cross section, and forms deep and widening vertical grooves on both pieces of an L-shaped metal fitting made of a metal plate. A cut-and-raised elastic connecting piece is formed by cutting and bending, and a fitting portion curved in a substantially semicircular arc shape is formed at the free end of the cut-and-raising elastic connecting piece, and the fitting portion is inserted into the vertical groove to form an L.
Since the shaped fittings are attached to the inside corners of the vertical corner members, it is possible to connect L-shaped fittings that are already L-shaped all at once, compared to the conventional method of attaching connecting fittings one by one. It has good workability, and since the connecting piece that connects to the vertical corner member made of inorganic material is cut and raised and is an elastic connecting piece, it can be connected to the L-shaped fitting to the vertical corner member so that it can be elastically displaced in the thickness direction. By changing the position of the L-shaped bracket with respect to the vertical corner member, if the surfaces of the vertical corner member and the exterior wall that butt against the sides are not aligned and there is a step, this step can be removed. It has the advantage that it can be attached tightly to the inner surface of the exterior wall of the L-shaped fitting. In addition, the vertical positions of the insertion portions of the plurality of cut and raised elastic connection pieces are shifted, and the insertion directions in the horizontal direction of the vertical grooves of the insertion portions that are adjacent in the vertical direction are different, so that the plurality of cut and raised elastic connection pieces are This has the advantage that the cut and raised elastic connecting piece can be inserted into the vertical groove at different vertical positions, and the insertion direction in the circumferential direction of the vertical groove can be shifted, allowing for a strong installation. .

In short, for vertical corner members made of inorganic materials, which are difficult to perform digging construction, this method improves workability by avoiding digging construction, solves problems caused by uneven thickness of exterior walls, and improves the connection strength. It is distinctive in that it is elevated.
