Description

[Detailed description of the invention] The present invention relates to a corner joint, and more specifically, it is a joint for arranging a bar member at each corner for attaching wall materials such as boards, and especially for pillars. The present invention aims to provide a new corner joint that greatly simplifies the installation of wall materials that intersect at right angles in a room with many protruding parts.

For example, as is well known, walls are constructed using predetermined wall materials such as various types of plywood and other boards, and at the corners, frame materials for attaching wall materials are adjusted to a predetermined length, and each end is The parts are welded so that they intersect at exactly right angles.

For this reason, in work where there are many protruding parts due to pillars, etc., and therefore many corners, it is time-consuming and requires skill to match the dimensions of frame materials and accurately weld, making it uneconomical and difficult to carry out the work. There were drawbacks such as an increase in costs.

The present invention relates to a new corner joint proposed to improve the above-mentioned drawbacks.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a frame material for arranging a wall material 2 in one direction; 3 is a frame material for arranging a wall material 2 in one direction;
A frame member 5 for arranging the wall member 4 orthogonal to the frame member 5 is a joint fitting that can connect the frame members 1 and 3 from the right angle direction.

The joint fitting 5 has both long and short arms 6, 7 bent into a substantially hole-shaped shape, and each arm 6, 7 has spring plates 8, 9 cut and raised facing toward the ends 5a, 7a, respectively. It is.

10.11 is an opening formed by cutting up the spring plates 8, 9, and the spring plates 8, 9 have convex portions 8a, 9a extruded from the inside to provide strength. Moreover, as is clear from the illustration, the ends 6a and 7a are designed to have a small diameter.

Note that the arm portions 6 and 7 may not be configured to be long or short, but may be configured to have approximately the same length.

The frame members 1 and 3 have a U-shaped cross section, and correspondingly, the cross-sectional shape of the joint fitting 5 is also approximately U-shaped.
Since it has a letter shape, each arm part 5a, 7a as shown in the figure.
Insert each end of the frame members 1 and 3 from the direction of the end so that it is positioned inside the spring plates 8 and 9.

With this, the back of each insertion member of the frame members 1 and 3 is attached to the spring plate 8,
Since the frame members 9 press, the frame members 1 and 3 are firmly held in their positions.

Of course, in this case, the frame members 1, 3 may be inserted deeply to the base ends of the arms 6, 7 depending on the dimensions of the location where they are arranged, or conversely, they may be inserted shallowly. , spring plates 8, 9
Since the frame members 1 and 3 are strongly pressed against the back side, the frame members 1 and 3 may move unnecessarily, interfering with the wall construction work, preventing the wall installation from becoming unstable, and preventing the cut dimensions of the frame members 1 and 3 from being Errors are allowed to some extent.

Further, the corner portion 12 of the joint fitting 5 is provided with elongated holes 13 and 14 in the right angle direction, respectively.
Numerals 3 and 14 are elongated holes into which a clip 16 for fixing the bar member 15 is inserted.

That is, the clip 16 has an ear portion 17 at the tip as shown in the figure.
It has an engaging part 19 consisting of a, 17 b and a constricted part 18, and a bent part 20 at an appropriate position on the base side.

Clips 16 are inserted into the long holes 13 and 14 of the joint fitting 5.
Insert the base side of the long hole 13.1 through the bent part 20.
Fold it inside 4 and lock it.

Now, the ears 17 a and 17 b of the slip 16 are as follows.
It is made to protrude slightly from the outer edge 5a of the joint fitting 5.

On the other hand, the bar member 15 has a U-shaped cross section and has bent locking portions 15 a and 15 b at both ends, and when the buck member 15 is inserted into the retaining portion 19 of the clip 16 , the above-mentioned The bending locking parts 15a, 15b are the ear parts 17a, 17
b engages with the constricted portion 18 and is securely fixed.

The corner joint of the present invention has the above-mentioned configuration, and its usage will be explained below. First, the joint fitting 5
The frame members 1 and 3 are inserted into the arm portions 6 and 7 at an appropriate depth from a right angle direction, and are held down with spring plates 8 and 9.

Then, the clips 16 are inserted into the elongated holes 13 and 14 through their base sides, the bent portions 20 are bent inward and fixed, and the bar member 15 is inserted into the retaining portion 19 and engaged, A wall material 2,
Fix the wall materials 2 and 4 with nails, screws, etc. so that the side edges of 4 are perpendicular to each other.

For example, as shown in the second figure, the frame members 1 and 3 are arranged using the joint fittings 5 horizontally, and the bar members 15 and 15 are arranged vertically via the clips 16, so that the wall members 2° 4 can be installed.

Since the corner joint of the present invention has the above configuration, it has the following effects.

In other words, the approximately L-shaped joint fitting 5 has arm portions 6 and 7 into which the frame members 1 and 3 can be inserted and connected from a right angle direction.
Moreover, since the frame members 1 and 3 can be held in place by pressing with the spring plates 8 and 9, if the frame members 1 and 3 are cut to approximately predetermined dimensions, the arms can be Dimensional adjustments can be made by suitably adjusting the depth of insertion into the holes 6 and 7, so the length of the frame material 1 can be easily adjusted to a predetermined exact size.

Therefore, it is possible to save the time and effort required for welding as in the past, and it does not require any skill to perform the work.In addition, if there is a dimensional error, the frame materials 1 and 3 must be cut or replaced with other materials and welding must be repeated. Such inconveniences will be resolved.

Further, the same effect can be achieved with the buck member 15, and the buck member 15 can be attached extremely easily via the clip 16.

As described above, by using the present invention, the efficiency of construction work involving many corners can be greatly improved compared to the conventional work.
