Description

[Detailed Description of the Invention] The present invention relates to a frame structure such as a door frame structure.

Conventionally, when a vertical frame made of synthetic resin requires strength, metal plates are inserted inside the frame, but insert molding is technically difficult, and it is difficult to assemble to connect it to the horizontal frame. The drawback was that it was bad.

The present invention was developed in view of the above points, and the purpose of the present invention is to easily attach a metal core material inside the vertical stile after molding the vertical stile of synthetic resin to strengthen it. To provide a stile assembly structure in which the stile can be reinforced with the same member even if the length of the stile changes somewhat, and furthermore, a horizontal board can be easily attached.

The present invention will be explained in detail below. The stile assembly structure of the present invention has a metal core material 2 vertically installed inside hollow cylindrical vertical stile 1 made of synthetic resin arranged to face each other, and a substantially L-shaped metal connection. The material 3 is inserted into the end of the vertical stile 1, and a piece 3a of the connecting material 3 is fixed with a screw 4 screwed into the outer surface of the end of the vertical stile 1, and a piece 3a is inserted between this piece 3a and the inner surface of the vertical stile 1. A horizontal board 5 is installed between the ends of the pair of vertical frames 1, which are arranged so as to sandwich the ends of the core material 2 and face each other, and connect both ends of the horizontal board 5 to the other piece 3b of the connecting member 3. It is fixed with screw 4. Next, the present invention will be explained in more detail with reference to Examples. Reference numeral 1 designates a vertical frame formed by extrusion molding of synthetic resin, and has a face plate fitting groove 6 recessed in one side surface over the entire length in the longitudinal direction. The core material 2 is a metal plate having a thickness of 0.6 to 0.3 mm, and has a U-shaped cross section. The connecting member 3 is also made of a metal plate having the same thickness as the core member 2, and has a substantially L-shape and a U-shaped cross section.
A mounting hole 7 having a smaller diameter than the screw 4 is bored in b. This approximately L-shaped connecting member 3 may be formed by integral bending as shown in FIG. 6a, or by butt welding 10 as shown in FIG. 6b, or by spot welding as shown in FIG. 6c. It may be 8. Further, the horizontal plate 5 is made of synthetic resin and is formed into an elongated plate shape. When assembling a stile using the members constructed as described above, it is carried out as follows. A core material 2 is placed inside the vertical stile 1 in the longitudinal direction, a connecting material 3 is placed inside each end of the vertical stile 1,
Screw the outer screw 4 of the vertical stile 1 into the mounting hole 7 of the piece 3a of the connecting member 3 to fix the piece 3a of the connecting member 3,
The end of the core material 2 is held between this piece 3a and the inner surface of the vertical stile 1. At this time, the length at which the piece 3a and the core material 2 overlap can be changed, so that even if the length of the vertical stile 1 changes somewhat, it can be accommodated. Two vertical frames 1 are arranged so as to face each other, both side edges of the face plate 9 are fitted into the face plate fitting grooves 6, and a horizontal plate 5 is constructed between the ends of the vertical frame 1. The horizontal plate 5 is attached by screwing the screw 4 into the attachment hole 7 of the other piece 3b of the connecting member 3. At this time, when the other piece 3b of the connecting member 3 is attached to the end face of the vertical stile 1 with screws 4, the sealing performance can be improved.

As described above, the present invention includes a metal core material installed vertically inside a hollow cylindrical vertical stile, and a metal approximately L-shaped connecting member inserted into the end of the vertical stile. One piece of the connecting material is fixed with a screw screwed in from the outside of the frame, and the end of the core material is sandwiched between this piece and the inner surface of the stile, so the stile is molded from synthetic resin. The core material can be easily installed and reinforced inside the rear stile, and by changing the length of overlap between one piece of the connecting material and the end of the core material, the same member can be used even if the length of the stile is slightly different. It can be reinforced with Because of this, the horizontal plates can be easily attached using connecting materials.
