Description

[Technical Field] The present invention relates to a door frame structure, and more particularly to a technique for performing a strong frame structure without creating a gap.

[Background Art] Conventionally, in a door frame structure, as shown in FIG. 5, the holding plates 1a, 1a formed on the vertical frame 1 are cut off over a length corresponding to the height of the horizontal frame 2, The end face of the horizontal frame 2 is brought into contact with the inner surface of the vertical frame 1 at the cutting point, and the tapping screw 8 inserted into the through hole 7 of the vertical frame 1 is attached to the horizontal frame 2 side tapping hole 9
The vertical and horizontal stiles 1 and 2 are connected by screwing in, but at the connection point, the vertical and horizontal stiles 1 and 2 are simply butted together. There is a problem that the horizontal frame 2 is conspicuous and the positioning of the horizontal frame 2 in the thickness direction is insufficient, and a shift easily occurs in this direction.

[Object of the Invention] The present invention has been made in view of the above problems,
It is an object of the present invention to provide a frame structure for a door that does not cause a gap in the abutting direction and can increase the connection strength in the thickness direction.

DISCLOSURE OF THE INVENTION A door frame structure of the present invention has a pair of sandwiching plates 1 on the inner side of each of the vertical frame 1 and the horizontal frame 2 over the entire length in the frame length direction.
a, 1a and sandwiching plates 2a, 2a are provided so as to face each other, and the sandwiching plate 1a is provided up to the longitudinal end edge of the vertical frame 1, and the cap 1 for closing the end opening of the vertical frame 1.
1, the insertion member 11a is provided with the sandwiching plates 1a, 1
It is inserted through a and fitted, and for butt connection at substantially right angles at the ends of the vertical frame 1 and the horizontal frame 2, the horizontal frame 2 on the side where the end faces in the frame length direction butt, A pair of inserting pieces 4 and 4 to be externally inserted on the outer surfaces of the holding plates 1a and 1a of the vertical frame 1 on the mating side are extended, and the tips of the inserting pieces 4 and 4 are brought into contact with the inner surface of the vertical frame 1. The vertical frame 1 and the horizontal frame 2 are connected by connecting means 6, and the outer peripheral portion of the door face plate 5 is clamped by the holding plates 1a, 1a and the holding plates 2a, 2a of the vertical frame 1 and the horizontal frame 2. This is a characteristic feature, and the above-mentioned object is achieved by such a configuration. That is, the horizontal frame 2 or the vertical frame 1 on the side where the end faces in the frame length direction are butted against each other.
A pair of insertion pieces 4 and 4 to be externally attached to the outer surfaces of the holding plates 1a, 1a of the vertical frame 1 or the horizontal frame 2 on the other side.
By vertically inserting 4 into the sandwiching plates 1a, 1a, the vertical frame 1
And the horizontal frame 2 at the abutting position, the holding plate 1a is internally provided.
1a is present, no gap is generated at the butting position, and since the insertion pieces 4 and 4 are externally attached to the sandwiching plates 1a and 1a, the vertical frame 1 and the horizontal frame 2 are positioned in the thickness direction. It is possible to improve the connection strength at the abutting point.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

The door A is constructed by assembling the left and right vertical frames 1 and 1 and the upper and lower horizontal frames 2 and 2 in a square frame shape, and holding the peripheral portion of the door face plate 5 in such a square frame 10. There is. The vertical frame 1 and the horizontal frame 2 are each provided with a pair of sandwiching plates 1a, 1a; 2a, 2a facing the entire length in the frame length direction on the inner surface of each of the frame main bodies of hollow rectangular pipes, respectively. . Although the vertical frame 1 and the horizontal frame 2 are butt-connected at substantially right angles to each other, the holding plates 1a, 1a of the vertical frame 1 on the mating side are attached to the horizontal frame 2 on the side where the end faces in the frame length direction are butted. A pair of insertion pieces 4 and 4 to be extrapolated to the outer surface of the. The distance between the insertion pieces 4 and 4 is substantially equal to the distance between the outer surfaces of the holding plates 1a and 1a. The lengths of the insertion pieces 4 and 4 are substantially equal to the protruding width of the holding plates 1a and 1a. The vertical frame 1 and the horizontal frame 2 thus configured are extruded products made of aluminum and synthetic resin.

Then, the insertion pieces 4 and 4 are externally attached to the sandwiching plates 1a and 1a, and the tips of the insertion pieces 4 and 4 are brought into contact with the inner surface of the vertical frame 1,
A tapping screw 8 which penetrates the fool hole 7a and the through hole 7b of the vertical frame 1 is screwed into a tapping hole 9 formed in the horizontal frame 2, and the vertical frame 1 and the horizontal frame 2 are connected by such connecting means 6. Of. And the end opening of the vertical frame 1 is the cap 1
Insertion member 11 closed at 1 and formed on the cap 11
A is inserted between the sandwiching pieces 1a, 1a, and the tapping screw 8 is inserted through the through hole 11b and fixed.

In this way, a pair of inserting pieces 4 and 4 for externally inserting the outer side of the sandwiching plates 1a, 1a of the other vertical frame 1 on the opposite side of the horizontal frame 2 where the end faces in the frame length direction are butted are extended and inserted. Holding plate 1, 4
By externally inserting into the a and 1a, the sandwiching plates 1a and 1a are present inside at the abutting position of the vertical frame 1 and the horizontal frame 2, and a gap is formed so as to penetrate the inside and outside of the door A at the abutting position. Never. Then, the sandwiching plates 1 and 4 are sandwiched by the holding plate 1.
By extrapolating to a and 1a, the vertical frame 1 and the horizontal frame 2 are positioned in the thickness direction, and the connection strength at the butted portions is increased.

In addition, although the insertion pieces 4 and 4 are formed on the horizontal frame 2 in the embodiment, the insertion pieces 4 and 4 may be formed on the vertical frame 1.

[Effects of the Invention] In summary, the present invention has an insert piece that is externally attached to an outer surface of a vertical frame or a horizontal frame holding plate of a mating side on a horizontal frame or a vertical frame on a side where end faces in the frame length direction are butted. Since the pair of pieces are extended and the insertion piece is externally inserted on the sandwiching plate, the sandwiching plate is present inside the abutting portion of the vertical frame and the horizontal frame, and there is a gap that penetrates the inner and outer surfaces of the door at the abutting portion. Since it does not occur and the insertion piece is externally attached to the sandwiching plate, the vertical frame and the horizontal frame can be positioned in the thickness direction, and the connection strength at the butted portion can be increased. The frame holding plate is provided up to the longitudinal edge of the vertical frame, and the insertion member provided in the cap that closes the end opening of the vertical frame is inserted between the vertical frame holding plates. Since they are fitted together, the end of the vertical frame can be efficiently processed with a simple cutting operation. Further, there is an advantage that the vertical frame holding plate on which the inserting piece is externally inserted is not bent inward, and the strength of the vertical frame holding plate in the thickness direction can be improved.
