Description

[Detailed Description of the Invention] This invention relates to a connection device for connecting a partition panel (hereinafter referred to as a panel) and a hollow square stud (hereinafter referred to as a stud), which is used in a large wall method of partitioning.

Conventionally, the large wall method of partitioning was used, in which panels were lined up on both sides of the studs (front and back) with multiple studs interposed between them, leaving joint grooves on the studs, or without leaving any grooves. In the method of connecting studs without exposing them to the front surface of the wall, connecting metal fittings, such as fittings or latches, are used between the studs and the panel, or between the back surfaces of the panels. It is made by attaching metal fittings.

However, panels, especially large walls, are large in both weight and shape, so minute differences in position and level (height and low) during installation (misalignment of studs and metal fittings installed on panels, differences in the shape of the metal fittings themselves) (or the tilt of the installation) are a major hindrance,
This has caused problems such as interfering with the fitting of the connecting fittings, making it impossible to continue holding the panel, and requiring time and effort to correct the position of the fittings.

Since the connecting fittings bear the weight of the panel, the structure of the fittings must be solid in terms of mass, and must be uniform and precise in order to avoid the above-mentioned curling. Since the top and bottom (especially the bottom), left and right, and front and back of the panel are fixed, the number of force parts increases and the shape tends to be complicated. The method of fastening is not easy as the screw holes do not match up. When fastening with a single screw, the metal fitting tends to tilt to the left and right, and when using two screws, in addition to the screw holes mentioned above, the metal fitting will be fixed at an angle, and you will have to worry about fixing it. .

As seen in general examples of latching, the latching pieces of the metal fittings are one pair on the left and right, and the panel is latched on either the left or right side, so a single screw is insufficient, and the light mass You can't avoid being vulnerable if you have something like this.

There were many problems with the structure of the connecting fittings, how to attach them, the stability of the panels, and the improvement of workability.

The present invention has realized a connecting fitting that does not shift, does not tilt or play, can withstand the weight of a large wall, and has good work efficiency as follows.

To explain this with drawings, 1 is Stud,
2 is a locking piece, and 3 is a panel. The device of the present invention is composed of these three components.

Stud 1 is a hollow rectangular prism made of metal,
On the surface portion (front surface 5, rear surface 6), symmetrically with respect to the vertical center line of the surface portion, the horizontal spacing (W) of the locking portion 2 is set, and the thickness of the locking portion is the width. A vertically long rectangular shape whose width is the height of the base part 7 and the hook 13 is drawn on the left and right sides, and this is punched into the hollow part to form transparent holes 8, 8. Placed above and below the
A transparent screw hole 9 is punched in the center between the transparent holes 8 and 8 (on the vertical center line), and an opening (opening 4 ), and its cross section is angular C-shaped.

The locking piece 2 has a horizontally long rectangle as a base part 7, which is vertically divided into three parts, with the center part being a middle piece 11 having a width of (W), and the left and right parts sandwiching it having the same size. As the wing pieces 12, 12, put a right-angled trapezoid on a part of the upper end of the wing piece 12 with the edges (lines) aligned, and attach the hanging claw 1.
3, 13, punch out a small flat metal plate with considerable wall thickness, bend the left and right wing pieces 12, 12 at right angles above the flat plate, and insert a screw hole 14 in the center of the middle piece 11. It is a small part made by cutting.

The panel 3 is constructed by pasting a metal top plate 16 on the surface of a thick panel-shaped backing material 15, bending the top plate 16 at right angles along the left and right ends of the backing material 15, and then Align the surface with the back surface of the backing material 15, bend it slightly outward at a right angle, and then bend the tip slightly at a right angle toward the top plate 16 to form a joint part 17 with an L-shaped cross section. 1
7 is horizontally cut out at a position corresponding to the transparent holes 8, 8 in the stud 1, with a width (V) or more equal to the height of the hook 13 added to the base part 7, to form an abutting part 18. It is something.

In order to connect the panel 3 to the stud 1 using the present invention, first, the stud 1, which is fixed upright, is
1. Attach the locking piece 2 to the opening 4 of the stud 1.
Insert it into the transparent holes 8, 8 of the stud 1 with the hooks 13, 13 facing up, and insert the wing piece 1.
1 and 11 on the surface, press the middle piece 11 tightly against the inner wall of the stud, pass the screw 19 through the screw hole 9 of the stud 1, turn the screw, and screw it into the screw hole 14 of the locking piece 2. Tighten and secure.

From one side of the studs 1, 1 to which the locking pieces 2 are attached, first lift up the first panel 3 a little, and insert the abutment part 1 of the joint part 17 on the first side.
8 and 18 on the hook 1 on the other side of the stud 1.
3, 13, the contact part 18 of the joint part 17 on the other side,
18 on one side of the other stud 1,
13, lower the first panel 3 a little and hang it in place. Repeat this pattern in turn and do the same on the other side to create a large wall panel.

According to the present invention, the wing pieces 12 and the hook 13 of the locking piece 2 are connected to the middle piece 11 and the through hole 8 of the stud 1.
8, it is firmly attached to the stud 1 so that screw 19 is almost not required, and the transparent screw hole 9 and screw hole 14 do not move toward each other correctly, so tightening with screw 19 is extremely easy. It is.

In addition, since there are no other inclusions on the surface of the stud 1 other than the protruding hook 13, this, combined with the simple shape of the abutment part 18, makes the construction work extremely efficient. was made into

The position of the locking piece 2 is the position of the through hole 8 of the stud 1, and it can be installed by simply inserting it without causing any confusion in the position. Even if it has a high strength, the ease of manufacturing and installation remains the same.

In addition, in the case of conventional fixing with a single screw, etc., we pointed out earlier that there is a failure due to latching on one side of the left and right locking pieces, but in the present invention, the case where the screw acts as a fulcrum for a lever to support an unbalance. does not occur at all.

The joint portion 17 of the panel 3 has a right-angled small frame shape (L
The firm shape of the panel 3 is brought into contact with the hook 13, and the trapezoidal slope of the hook 13 is directed toward the stud 1 to facilitate the entry of the panel 3 from above. Holding forward motion, wing piece 12
regulates vertical movement. Therefore, it is sufficient to fix the panel 3 left and right, top and bottom, and front and back.

Note that part of the panel 3 can be easily removed or replaced by, for example, slightly lifting the panel 3 in the above-mentioned state from below.

As a connecting device for large wall panels, this invention has achieved the outstanding effects described above and is extremely useful industrially.
