Description

[Detailed Description of the Invention] This invention relates to a device for connecting studs and sills in a partition.

Conventionally, in the construction of partitions, devices for connecting studs and partition wall panels (hereinafter referred to as panels) or panels to each other have made it possible to easily erect panels using a so-called one-touch method. However, attaching beams to studs, which is one of the preparatory steps before installing panels, still relies on cumbersome methods. That is, for example, first, a receiving bracket, which is a small part made of metal or the like bent into an L shape, is attached to the indicated position of the stud with screws, and a U-shaped channel material, which is a nakasho, is hooked to this, For example, the nakasho and the receiving metal fittings are further screwed together to connect them.

The first defect in this method is the fastening by screws. This poses an obstacle to accurately attaching the nakasho at the required location. In other words, the position of the stud may be misaligned due to misalignment that occurs when cutting a screw, misalignment of the screw hole between the receiving metal fitting, stud, or stud, or a crushed screw thread or misalignment with the thread groove. This is because it is easy.

Nakasho is used for the purpose of reinforcement to form a frame with studs, etc., and to keep the attached panel firm and stable.On the other hand, it is used for the purpose of reinforcement for panels that have become standardized and have lost flexibility. The purpose is to create a space according to the standard, prevent the panels from tilting and unevenness (front and back tilting), and give the partition a beautiful finish, but the method of fixing with screws does not meet this purpose. In addition, the work required a lot of skill and time.

In view of these points, the purpose of the present invention is to make the installation of the Nakasagi etc. accurate and easy, and
This was done in search of a solution that does not use screws.

Hereinafter, an example will be explained with reference to the drawings.
The device of the present invention consists of a stud 1, which is a stud, a channel material 2, which is used as a crosspiece, and a receiving metal fitting 3, which is a connector for fixing these.

The stud 1 is made of a hard metal material (hereinafter the same applies to the channel material 2 and the receiving metal fitting 3), and is made of a hollow rectangular prism with opposing left and right side surfaces 4, 4 (the front and rear sides contact the panel 5, etc.). surface)
, punch out two small vertical rectangular slots symmetrically to the center vertical line of the surface, and make the slits 6,
6 is provided at one or more locations on the side surface portion 4. The position and shape of the slit 6 must be provided equally and precisely on the studs 1, 1, . . .

The stud 1 does not have to have a rectangular cross section, but may have a triangular, pentagonal, etc., or, for example, a C-shape with openings on the sides. Alternatively, the column may be hollow only in the portion where the slit 6 is punched. In these other examples as well, the surface on which the center beam is attached will be similarly referred to as the side surface portion 4.

The channel material 2 is a horizontally elongated frame material having a U-shaped cross section and having an opening at the bottom. On the top surface 7, a small vertically long rectangle is punched out symmetrically to the horizontal center line and parallel to the line of the end 8, leaving the edge piece 14 with a small width from the left and right ends 8, 8. Transparent hole 9,
9. The width of the transparent hole 9 is the same as the stud 1 mentioned above.
This is the width of the slit 6, and the vertical width is approximately equal to the width of the locking claw 11 of the receiving metal fitting 3, which will be described later.

The height of the receiving metal fitting 3 shown in FIG. 2A of the drawing is made approximately equal to the length of the vertical width of the slit 6 in the stud 1, and its wall thickness is made approximately equal to the length of the width of the slit 6. A small horizontally long rectangular member is vertically divided into three sections, with the center section being the center piece 10 and the left and right sections being the wing pieces 12, 12.The width of the center section 10 is equal to the width of the side surface 4 of the stud 1. The length is calculated by subtracting the length that is twice the wall thickness width of the channel material 2 from
Further, on the upper side of the blade 1, a rectangular small protruding locking pawl 11 is provided symmetrically to the vertical center line at a height of a small width.
It is a small part in the shape of parts 2 and 12 bent at a right angle to the rear. The width of the locking pawl 11 is the length of the vertical width of the through hole 9 of the channel material 2, and as shown in FIG. It may be formed. The wing piece 12 has its lower side 1
3 toward the upper side 15, a notch 16 is made along the thickness of the side surface 4 of the stud 1, and the remaining claw-shaped end piece is used as a hanging claw 17. Notch 16
The position to insert the center piece 1 is from the tip of the wing piece 12.
The inner diameter reaching the inner wall of 0 (rear surface in the front and rear surfaces) is W
Then, from this W to the edge piece 14 of the channel material 2
This is the point where the length of the width is subtracted from the inner wall side of the center piece 10, and the notch 16 does not come out up to the upper side 15, and that part (the notch part) is punched out (cut out).

To use the device of the present invention having the above configuration, the receiving metal fittings 3, 3, . Insert the hooks 17, 17 of the receiving metal fitting 3 into the slits 6, 6 of the stud 1 with the locking claws 11 facing upward, catch the side surface 4 at the notch 16, and lower it as it is to lock it.

In this case, since the vertical cross section of the hook 17 of the receiving metal fitting 3 has approximately the same size and shape as the vertically elongated rectangle formed by the slit 6, insertion can be easily performed, and the groove width of the notch 16 Since is equal to the wall thickness width of the side surface portion 4, the connection and fixation by the hanging claws 17 is very firm. That is, the connection between the stud 1 and the receiving metal fitting 3 is easy and strong.

Next, interpose the channel material 2 between the two studs 1, 1, place the channel material 2 with its opening 18 facing down, and lift the other end 8 a little. Fit one transparent hole 9 into the locking pawl 11, lower the other end 8, and keep it in a horizontal state. Fit the hole 9 and the installation is completed.

In the above, for convenience of explanation, the order was given as one first and then the other, but in practice, the channel material 2 is attached to the two studs 1, 1 at the same time, and therefore the stability of the studs 1, 1 is It was obtained quickly and the work efficiency was outstanding.

Also, the through hole 9 of the channel material 2 is connected to the receiving metal fitting 3.
snugly fit onto the locking claw 11 of the channel material 2.
By fitting the edge piece 14 between the receiving metal fitting 3 and the stud 1 without a gap, the channel material 2
Since the left-right, front-back, and downward movements of the studs 1, 1 (and the studs 1, 1) are strictly controlled, the connection between the channel material 2 and the studs 1, 1 is strong.

The other most significant effect of the present invention is that the position and attachment state of the channel material 2 can be maintained accurately. As previously mentioned, the difficulty of maintaining accurate positioning in conventional methods such as screw fixing is difficult, but in the present invention, both the drilling of the slit 6 in the stud 1 and the drilling of the transparent hole 9 in the channel material 2, It can be applied accurately in position and shape, does not require any modification later, and the structure of the receiving metal fitting 3 is simple and the mass (wall thickness, etc.) is also strong, so it can be made accurately. I can do it. Therefore, for example,
The channel material 2 will not protrude too much from the side surface 4 of the stud 1, or will not be recessed or misaligned. In addition, the distance between the two studs 1, 1 can always be maintained correctly by connecting the channel material 2, whereas in the conventional method, the distance between the studs 1, 1 is different on the top and bottom, and the panel 5 This solves the problem of obstructing the locking means.

In addition, the reinforcement of the stud 1 should not be effective only by connecting the left and right sides as described above. In the conventional method, even if reinforced with the channel material 2, it was not possible to prevent the studs 1, 1 from tilting back and forth, and there were cases where the panel 5 could not be hung smoothly, but in the implementation of the present invention. These studs 1,1
This allows the user to easily and stably stand upright without worrying about tilting forward or backward.

Next, I still have an explanation. Regarding the receiving metal fitting 3 in Figure 2B of the drawing, in this case, the central piece 10
Of the two locking claws 11 on the top, the channel material 2 is attached only to the one on the panel 5 side, and other parts on the other side - in this case, it is possible to fill with the sound absorbing material 19. It can be used with various other contents. The part where the channel material 2 and the receiving metal fitting 3 overlap (the part where the width from the end part 8 to the extension line 21 of the through hole 9 is taken vertically and vertically to one side of the leg side 20)
is used at this point.

The channel material 2 of the present invention can be used as a window frame or a rolling frame.
