Description

[Detailed Description of the Invention] The present invention relates to a structure of a part of a corner of a wall, which is constructed by attaching a corner member having a road-like cross section to the corner of a pillar material such as a pillar or a rim.

When attaching a corner member with a cross-sectional road shape to the corner of a pillar material and closing the space between the wall materials that are attached to two adjacent sides of the pillar material, conventionally, the corner material was attached to the pillar material by nailing or gluing. It was done with drugs.

However, when fixing a corner part by directly nailing it, the nail head is exposed and the corner part, which must be functionally hard, is likely to crack, so it is necessary to drill a pilot hole in advance. Not only is it time-consuming to install, but the exposed nail heads also worsen the appearance.

And even when adhesives are used, the workability is poor,
There were disadvantages in that adhesive strength varied and the cost of the adhesive was high.

The present invention was devised in view of these points, and its purpose is to fix the pillar material of the corner material without directly nailing the corner material or using adhesive. The installation can be carried out in the corner of the wall to provide some structure.

To explain the present invention below, the present invention provides a locking recess at the inner corner of a corner member having a road-like cross section, and also provides a notch on the inner surface of the side end of the corner member, thereby locking the corner member. A plate-shaped connector having a locking piece and a projecting piece that are respectively locked in the recessed part and the notch part and protruding from the surface side is fixed to the pillar material, and a corner part is attached to the corner of the pillar material. With this configuration, one corner member is attached to a column member via a connecting tool without driving a nail into the corner member.The present invention will be described in detail below based on the illustrated embodiment. do.

In the figure, 1 is a corner member, 4 is a connector, and 3 is a pillar member such as a pillar or a rim.The corner member 1 has a road-like cross section, and the inside corner has an actual part extending over almost the entire length in the longitudinal direction. A locking recess 2 having a T-shaped cross section is formed with a T-shaped cross section that widens on both sides, and a notch 7 is formed on the inner surface of the side end portion over substantially the entire length in the longitudinal direction.

One surface of the corner of this notch 7 reaching the inner surface of the member 1 is
The corner is inclined so that the angle between the inner surface of the member 1 and the inner surface of the corner member 1 is an acute angle.

The connector 4 made of a metal plate is provided with a locking piece 5 protruding from the surface side and having a cross-section with a base piece 5a and a tip piece 5b forming a substantially right angle on the negative side. A friction engagement protrusion 6a is provided on the outer surface of the base piece 5a, which is the protruding base side of the stopper piece 5.

The connector 4 also has a plurality of holes 9.9 at the other end,
As shown in FIG. 2, projecting pieces 8, 8 are cut and raised in a substantially rectangular shape between the hole 9 and the locking piece 5, and have tips protruding toward the surface side.
It is equipped with

Therefore, when attaching the corner member 1 to the corner of the pillar member 3, the locking piece 5 of the connector 4 is inserted and locked into the locking recess 2 of the corner member 1, and the protruding piece 8 is engaged with the notch 7. Then, the connecting tool 4 is attached to a predetermined position in the longitudinal direction of the corner member 1 by being held by the locking piece 5 and the projecting piece 8.

At this time, the frictional engagement protrusion 6a provided on the locking piece 5 frictionally engages with the inner wall of the locking recess 2, thereby making the attachment of the connector 4 to the corner member 1 more secure.

Next, the connecting tool 4 is placed in such a way that the large corner of the corner member 1 is brought into close contact with the corner of the pillar material 3, and the back surface is brought into contact with one surface of the pillar material 3.
The corner member 1 is fixed to the column 3 by driving a nail 10 into the column 3 through a hole 9 located at a position protruding from the side end.

The corner member 1 is attached to a pillar member 3 via a connector 4.

Thereafter, a wall material 11 is erected in connection with the corner member 1 to hide the nail 10 and one side end of the connector 4.

Incidentally, the connector 4 may be first fixed to the pillar member 3, and then the corner member 1 may be attached to the connector 4.

If the locking piece 5 is provided over the entire length of one side edge of the connector 4 as shown in the illustration, and a plurality of protruding pieces 8 are provided, the locking piece 5 will extend over the pair of corner members 1, 1 disposed above and below. Since a single connector 4 can be attached, it is possible to improve the fit of the joint between the corner members 1.

The one shown in FIG. 3 has a base piece 5a with a locking piece 5 at the tip so that the effect of the frictional engagement protrusion 6a described above is stronger.
A frictional engagement piece 6b is cut and raised from the connector 4 toward the back side, and a frictional engagement protrusion 6a is provided on the outer surface of the tip of the frictional engagement piece 6b. An example is shown in which the frictional engagement between the frictional engagement projection 6a and the frictional engagement protrusion 6a is made stronger.

As described above, in the present invention, the corner member is attached to the corner of the column material via the connector, and the connection between the connector and the corner member is achieved by a lock provided on the corner member. This is done by locking the locking piece and protruding piece of the connector in the recess and notch, respectively, and there is no need to nail the corner member, making it easy to attach the corner member to the pillar member. It is something that can be done.
