Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure for attaching a door frame to a wall panel, which allows the attachment piece of the door frame to be easily attached and detached from the front side of the wall panel.

[Background technology]

Conventionally, when attaching a door frame to a wall panel, as shown in FIG. 8 from the front side of the door frame 9, fit the nut 3 into the tip of this screw 12 on the back side of the wall panel 7, and tighten the screw 1.
2, the door frame 9 and wall panel 7 were fixed together. However, in this case, if it becomes necessary to remove the door from the wall panel 7 for maintenance after the door frame 9 is attached to the wall panel 7, turn the screw 12 from the front side of the door frame 9 in the loosening direction. Also, nut 3 is spinning idle and screw 1
2 may not come out, and screw 1 may not come out properly.
Even if it were possible to pull out the nuts 3, when reattaching the door frame 9 to the wall panel 7, it would not be possible to fit the nuts 3 into the screws 12 by turning the hand to the back side of the wall panel 7, and in the end, the building would be damaged. There was a problem that the work had to be done by tearing down the wall. In addition, as another method for attaching the wall panel 7 to the door frame 9,
As shown in FIG. 2, there is also a method of welding or gluing a nut 3 to the back of the wall panel 7 in advance, and then screwing a screw 12 passed through the front side of the door frame 9 into this nut 3. With this method, the adhesive 13 etc. may enter the threaded part of the nut 3 and cause screwing failure, and the position of the nut 3 is fixed, so if the nut 3 is misaligned, the door frame 9 There was a drawback that the screw 12 could not be screwed into the screw hole 4 of the nut 3 from the front side.

[Effect of idea]

The present invention has been developed in view of the above points, and provides a structure for attaching a door frame to a wall panel, which allows the door frame to be attached to or detached from the wall panel by turning screws from the front side of the door frame. The purpose is to provide the following.

[Disclosure of invention]

That is, the present invention has screw insertion holes 2, 2 facing each other in the bottom and top surfaces of the nut storage box 1,
A nut 3 is housed in the box 1 so that the nut 3 can be moved vertically and horizontally but not rotated, with its screw hole 4 corresponding to the screw insertion hole 2, and a mounting piece 5 is extended to the bottom of the box 1. to form a door mounting bracket 6,
Attach the door mounting bracket 6 to the back side of the wall panel 7, and drill a wall panel screw hole 8 in the wall panel 7 at a position corresponding to the screw insertion hole 2 of the door mounting bracket 6, and attach it to the front side of the wall panel 7. Mounting plate 10 for door frame 9
Door frame screw hole 1 drilled in mounting plate 10 by arranging
1 into the wall panel from the front side, and the tip of the screw 12 is inserted into the wall panel screw hole 8 and the screw insertion opening 2, and is screwed into the screw hole 4 of the nut 3. The above objective has been achieved by the mounting structure of the door frame.

The present invention will be explained in detail below with reference to Examples. As shown in FIGS. 5a and 5b, the door mounting bracket 6 is formed by providing a plurality of nut storage boxes 1 on a mounting piece 5 having an L-shaped cross section. Screw insertion holes 2, 2 are formed opposite to each other in the bottom and top surfaces of the nut storage box 1, and a nut 3 is movably housed in the box 1. In this embodiment, the box 1 is formed into a rectangular shape in front, and the nut 3 is formed into a square whose size is slightly smaller than that of the box 1, so that the nut 3 can be moved vertically and horizontally within the box 1. It is set as. Further, the length of the diagonal line of the nut 3 is set longer than the width or the length of the inside of the box body 1, so that the nut 3 cannot rotate around its screw hole 4.
Further, when the nut 3 moves inside the box body 1, the screw hole 4 of the nut 3 is always visible from the outside through the screw insertion hole 2 of the box body 1, so that it corresponds to the screw insertion hole 2 and is inserted into the box body 1. It's stored. In the figure, reference numeral 14 denotes a double-sided adhesive tape, and when attaching this door mounting bracket 6 to the back side of the wall panel 7, use this double-sided adhesive tape 1.
4, the door mounting bracket 6 is attached to the wall panel 7 as shown in FIGS. 3 and 4. A fixing piece 15 is bent and extended on the side of the wall panel 7, and a wall panel screw hole 8 is bored in the fixing piece 15 at a position corresponding to the screw insertion hole 2 of the door mounting bracket 6. It has been set up. Fixed piece 1 of wall panel 7
5 A mounting plate 10 for the door frame 9 is arranged on the front side, and a door frame screw hole 11 is bored in this mounting plate 10 at a position corresponding to the screw insertion hole 2 of the door fixture 6. be. In the figure, 16 is a foam. Screw 1 screwed into door frame screw hole 11 from the front side of door frame 9
2 is inserted into the wall panel screw hole 8 and the screw insertion hole 2 of the door mounting bracket 6, and its tip is inserted into the nut 3.
It is screwed into the screw hole 4 of. In the figure, 17 is a door attached to the door frame 9 so as to be openable and closable, 18 is a sealing material, and 19 is a glass plate.

Therefore, when attaching the door frame 9 to the wall panel 7 with screws, attach the door mounting bracket 6 to the back side of the wall panel 7 in advance. )Twist screw 12 into door frame screw hole 1
1 and into the wall panel screw hole 8, and then tighten the tip of the screw 12 into the screw hole 4 of the nut 3.
Here, since the nut 3 can freely move vertically and horizontally within the box 1 of the door mounting bracket 6, there may be slight errors in the mounting position of the wall panel 7 and door frame 9 and the pitch of the screw holes 8 and 11. By moving the nut 3 within the box body 1, the screw 12 can be screwed into the nut 3 without any problem. Furthermore, when removing the door frame 9 from the wall panel 7 in order to change the layout of the room, etc., the nut 3 is prevented from rotating within the box body (1), so the nut 3 will not rotate idly. Instead, the door frame 9 can be removed simply by turning the screw 12 from the front side of the door frame 9. Furthermore, this door mounting bracket 6
has a plurality of boxes 1, 1 spaced apart from each other, and therefore, by attaching the door mounting bracket 6 to the wall panel 7, a plurality of nuts 3 can be simultaneously arranged on the back side of the wall panel 7. Since it is possible to do this, there is no need to install the nuts 3 one by one, and the installation work can be easily performed. Further, the door mounting bracket 6 is formed of a long L-shaped member, and can also reinforce the wall panel 7 at the door mounting portion.

[Effect of idea]

As described above, the present invention has screw insertion holes that are opposed to each other in the bottom and top surfaces of the nut storage box, and the nuts are inserted into the box in such a manner that the screw holes correspond to the screw insertion holes in the upper, lower, left, and right directions. It is stored so that it can be moved and not rotated, and a mounting piece is extended to the bottom of the box to form a door mounting bracket.The door mounting bracket is attached to the back side of the wall panel, and the door is attached to the front side of the wall panel. After arranging the frame mounting plate, screw the screw into the door frame screw hole from the front side, insert the tip of the screw into the wall panel screw hole and screw insertion hole, and screw it into the screw hole of the nut. When turning, the screw can be screwed into the nut without the nut turning idly, and the door frame can be attached to or removed from the wall panel by turning the screw without seeing the front of the door frame. In addition, the nut can be moved inside the box and fitted to the screw, so even if there is a misalignment between the door frame and the wall panel, you can move the nut and finely adjust the nut position to fit the screw into the nut. It can be screwed into a screw hole without any problem.
