Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a window frame connection device that improves the strength and watertightness of the right-angled connection portions of window frame members.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
The drawings show an embodiment in which the present invention is applied to a bay window, and 1 shows an example in which the upper, lower, left, and right outer frame members 1a to 1c are made of shapes with the same cross-sectional shape, and these outer frame members 1a to IC are connected in a rectangular frame shape. This is the outer frame.

That is, the outer frame members 1a to 1c are provided with a hanging wall portion 3 at the front edge of a slanted wall 2, and a mounting piece portion 4 is formed by bending the lower edge of this hanging wall portion 3 into an L-shape toward the back side. A leg portion 5 is bent outward at the base of the inclined wall 2, and a mounting piece 6 is extended from the inner surface of the base.

Further, a connecting fitting 7 as shown in FIG. 6 is manufactured separately.

This connecting fitting 7 is an L-shaped fitting, and both walls thereof are slanted walls 8a and 8b, and a connecting flange portion 9° 10 is bent at a substantially right angle along both edges of the connecting fitting 7. A plurality of screw holes 11 are formed in each of the connecting flange portions 9 and 10.

When connecting the outer frame members, for example, the outer frame members 1
The ends of a and 1c are cut diagonally at 45 degrees, and screw insertion holes 12 are bored in the mounting pieces 4 and 6 on this end side of each outer frame material 1a and 1c, and then the outside Frame material 1
The diagonally cut ends of a and lc are butted together in a fastening joint structure, and the connecting fitting 7 is abutted against the inside of the joint portion of both outer frame members that are butted at right angles, and the mounting piece portion 4 and the joining flange portion are abutted against each other. Screw insertion holes 12 with holes 3, 6 and 10 provided here.
The screws 13 are fixed using the screw holes 11.

As a result, the outer frame members 1a and 1c are connected by the connecting fitting 7, and the gap created between the outer frame members 1a, 1c and the connecting fitting 7 is filled with foaming synthetic resin 14 (Fig. 4). and Figure 5).

Through such a procedure, the outer frame 1 is constructed by connecting the outer frame members 1a to 1c.

Next, the inner frame members 15a, 1
An inner frame 15 extending from 5b is attached to the inner peripheral portion of the outer frame 1 in the same square frame shape.

In order to attach this inner frame 15, as shown in Fig. 2, the outer frame material 1
Using the mounting pieces 4 and 6 of a to 1c, support hardware 16 to 1 is attached.
9 is fixed with screws 20... and this supporting metal fittings 16 to 1 are fixed.
9, the inner frame material 15a.

15b is fixed by means including screws 21.

The integral part of the outer frame 1 and the inner frame 15 is the window part 2 of the building 22.
3 from outside, and is attached by welding with a mounting hardware 26 interposed between the anchor hardware 25 fixed to the building 22 side by an anchor bolt 24 and the support hardware 17, 19.

Reference numeral 27 indicates a window sash installed in the inner frame 15, 28 indicates each caulking agent, 29 indicates a decorative cover plate, and 30 indicates a drain hole provided in the outer frame material 1b.

That is, conventionally, when connecting window frame members, an L-shaped plate-shaped corner fitting is inserted between the window frame members at the joint portion of both window frame members that are butted at right angles, and the window frame members are connected to each other. This was done by inserting a screw into one window frame member from the outside and screwing it into the screw pocket of the other window frame member using a screw pocket provided in the window frame member.

Therefore, the above-mentioned corner fittings are not fixed to the window frame members, which poses a problem in connection strength, and the two window frame members cannot be completely sealed, causing rainwater to enter through the joints. It has become.

Furthermore, the heads of the screws are exposed to the outside, which is unsightly, and rainwater also enters through the screw heads.

However, according to the present invention, when connecting the outer frame members 1a to 1c, the mounting pieces 4 and 6 are provided on the indoor side and the inner surface of the outer frame members, and L-shaped fittings are provided on both ends of the mounting pieces 4 and 6. The connecting flange portions 9 and 10 are approximately perpendicular to each other along the edge of the shape.
A connecting fitting 7 formed by bending is installed between the mounting piece parts 4 and 6 at the joint part of the circular outer frame material 1atlc to form the mounting piece part 4.
, 6 are fixed to the connecting flanges 9, 10, thereby forming the outer frame member 1a.

Synthetic resin 1 is placed in the gap formed between 1c and the connecting fitting 7.
4 is filled with foam, the connection strength between the outer frame materials 1a and lc is dramatically improved by the outer frame material 1a and the connecting fittings 7 fixed to the IC, making it extremely resistant to shock and vibration. An outer frame 1 is constructed.

Furthermore, since the fastening joints of the circular outer frame members 1a and lc are sealed from the inside by the foam filling of the synthetic resin 14, rainwater is prevented from entering the outer frame 1 from the fastening joints, that is, the outer frame corners. At the same time, it is possible to prevent rainwater from entering between the outer frame 1 and the inner frame 15 from flowing out from the fastening joints of the outer frame members 1a and lc. The water will definitely be drained to the outside.

Furthermore, since the screw heads are not exposed to the outside, the appearance is good, and rainwater does not enter through the screw heads, resulting in a connection structure with even better watertightness.

Therefore, the present invention provides a window frame that is useful in terms of strength, watertightness, and drainage.
