Description

[Detailed description of the invention] - Industrial field of application - This invention relates to a fixture used to attach and fix a door frame to a C-channel pillar of an assembly house or the like from the front.

-Prior Art- A conventionally known fixture for a door frame for an assembled house is described in Japanese Utility Model Publication No. 55-22149. This fixture is a short channel-shaped door frame with a screw fitted with a roughly diamond-shaped tightening piece that can be positioned inside the hollow part of the C channel where the door frame is attached, and the tightening piece is attached to the opening of the C channel. By inserting from C and rotating the screw,
Front plates located on both sides of the channel opening are clamped and fixed between the fastening pieces and the door frame.

-Problems that the invention attempts to solve- This fixture is convenient because the door frame can be fixed to the C channel simply by turning the screw, but both ends of the tightening piece are completely attached to the C channel. It is not possible to confirm whether or not it is installed on the back of the front panel, and if the installation is incomplete, there is a risk that the fastening piece may rotate and come off due to vibrations that occur when the door opens and closes. Since the C-channel and the door frame are fixed with the fastening pieces slanted, the door frame and the C-channel will not connect if an impact force is applied from a direction parallel to the front plate of the C-channel (lateral direction). There is a risk of it shifting.

SUMMARY OF THE INVENTION The object of the present invention is to provide a new door frame fixture that is simple in structure and does not have the above-mentioned drawbacks.

- Means for Solving the Problems - Explaining using the reference numerals in the drawings, the fixture 11 according to the present invention consists of a pair of fixing devices interposed from both sides between the door frame 7 and the C channel 2. Boards 12 and 1
A structure is adopted in which the door frame 7 is fixed with 3. Each of the fixing plates 12 and 13 has a stepped portion 15, 22 at its tip that abuts against the edge 5R, 5L of the C channel 2, and a convex piece 16 extending from the stepped portion to the back side of the front plate 6R, 6L of the C channel. 23, and has holding pieces 18 and 29 at the base end that abut against the side surface of the door frame 7, and its cross section is L-shaped with a hook-shaped portion at the tip.

The fixing plates 12 and 13 are provided with a screw hole 24 in the center of at least one of them, and when the screw hole 24 is provided in only one fixing plate, the screw hole 24 is provided in the other fixing plate or both fixing plates. In this case, the door frame 7 is provided with a horizontally long elongated hole 19 through which the screw 20 screwed into the screw hole 24 is inserted. That is, according to the embodiment in which the fixing plates 12 and 13 are mounted by overlapping each other, the fixing plate 13 on the C channel 2 side is provided with a screw hole 24, the other fixing plate 12 is provided with a long hole 19, and the other fixing plate 12 is provided with a long hole 19. A fixing plate 12 is fixed to the door frame 7 with fixing bolts 14. Further, according to an embodiment in which the fixing plates 12 and 13 are not overlapped, screw holes 24 are provided in both the fixing plates 12 and 13, and the long holes 19 are provided in the door frame 7.
established in

-Function- The fixing plates 12 and 13 attached to the door frame 7 with the screw 20 or the screw 20 and the fixing bolt 14 are
By loosely fastening them, at least one of them 13 can swing laterally along the elongated hole 19. Therefore, when the fixing plates 12 and 13 are attached to the door frame 7 and the distance between the fixing plates is widened, the projecting piece 16 of one of the fixing plates 12 is attached to the front plate 6R of the C channel.
By sliding the other fixing plate 13 toward the fixing plate 12, the protruding piece 23 of the fixing plate is inserted into the back side of the front plate 6L on the opposite side of the C channel 2, and in this state By tightening the screw 20, the fixing plates 12 and 13 are fixed to the C channel 2. The door frame 7 is fixed to this fixing plate by fixing bolts 14 or to fixing plates 12 and 13 by the screws 20 themselves.

If the door frame 7 is fixed to the C channel 2 as described above, the convex pieces 16 of the fixing plates 12 and 13,
23 are fastened to the back surfaces of the front plates 6R and 6L of the C channel, so that the fixture 11 can be securely locked to the C channel 2, and there is no risk that the fixture will come off due to vibrations caused by the opening and closing operations of the door. . Further, the stepped portions 15 and 22 of the fixing plates 12 and 13 are brought into contact with the edges 5R and 5L of the C channel, and the holding pieces 18 and 29
Since the C channel 2 and the door frame 7 are fixed in contact with both sides of the door frame 7, even if a lateral impact force is applied to the door frame 7, the C channel 2 and the door frame 7 will not be displaced.
