Description

[Detailed Description of the Invention] The present invention aims to provide a bay window for use in cold regions that has particularly excellent heat insulation structure.

Hereinafter, one embodiment of the present invention will be described based on the drawings. As shown in FIG. 2, upper and lower frames 1a, lb, left and right side frames 1c,
A window frame 1 is constituted by the lc, and a front window section of a bay window main body 3 is constituted by fitting window shoji 2, 2 into this window frame 1, and a required insulation space 4 is provided for this front window section. Upper and lower frames 5a, 5b and left and right side frames 5c, 5c are provided on the base side of the bay window main body.
A window frame 5 is constructed, and a window sash 6.degree. 6 is fitted within this window frame 5.

A top plate 7 is installed between the upper frames 1a and 5c of both window frames 1 and 5, and a roof plate 8 made of a heat insulating wall material (for example, Styrofoam sandwiched between plywood and metal plates) is installed on top of the top plate 7. The roof board 8 is placed on the roof plate 8 through the upper frame 1a.
Nails 9 are driven into the roof board 8 through the spacer 10 between the top board 7 and the roof board 8, and nails are driven 11 into the roof board 8 through the spacer 10 from the top board 7 side, and between the roof board 8 and the upper frame 5a. A support fitting 12 is interposed between the support fittings 12, and both ends of this support fitting 12 are nailed 13 and screwed 14 to the roof plate 8 and the upper frame 5a, so that the roof plate 8 is placed on the front and rear window frames 1 and 5 at an appropriate slope. It is fixed with

Further, from the upper frame 5a, there is a supporting leg piece 1 that supports the base of the roof board 8.
A frame 16 is attached to the top base of the roof board 8 in correspondence with the tips of the supporting leg pieces.

In this installation, the frame 16 has an engaging groove 16b on the lower surface, and the cylindrical nut 17 with washer is installed so that the washer 18 engages with the engaging groove 16b, and the roof plate is attached from the supporting leg piece 15 side. The frame 16 is fixed to the roof board 8 by screwing a screw 19 passing through the roof plate 8 into the cylinder nut 17.

In this installation, from the frame 16, the connecting piece 1 with the building side structure is attached.
6a is formed by an upper mold, and a connecting piece 20 for the same purpose is also formed to hang down from the upper frame 5a.

On the other hand, a fitting groove 21 is formed on the back of the lower frame 1b of the front window frame 1, and a base plate 22 is formed of the same type of heat insulating wall material as the roof plate 8.
The tip of the main plate 22 is thrust into engagement with the fitting groove 21, and the base plate 22 is fixed to the lower frame 1b by nailing 23 at the curved portion, and the rear end of the base plate 22 is brought into contact with the lower surface of the lower frame 5b of the rear window frame 5. and the lower frame 5b is placed between the base of the main plate 22 and the main plate 22 is sandwiched between the base plate 22 and the lower frame 5b.
For installation, a frame 24 is attached correspondingly.

An engagement groove 25 is formed on the lower surface of the lower frame 5b, and the cylindrical nut 17 with a washer is engaged with the engagement groove 25 by the washer 18, and the mounting is done by penetrating the base plate 22 from the frame 24 side. Screw the screw 26 into the cylinder nut 17 and attach the lower frame 5b.
The base plate 22 and the mounting frame 24 are integrally fixed.

For installation, connect the frame 24 to the building side structure using the piece 24a.
is formed to hang down, and a connecting piece 27 for the same purpose is also formed in a single character shape on the lower frame 5b.

At the sleeve part of the bay window main body 3, a side plate 28 cut out from the insulating wall material is applied between the outer surfaces of the side frames 1c and 5c of the front and rear window frames 1 and 5, and nails 47 (fourth
(Fig.), and on the rear window frame 5 side, screws 31.32 (Fig. 3) are screwed into the screw pockets) 29.30 (Fig. 2) of the upper and lower frames 5a and 5b (Fig. 2) through the side plate 28. The side plate 28 is fixed.

Further, an edge member 33a (FIG. 3) made of synthetic resin and having a U-shaped cross section is attached to the lower surface of the roof plate 8 by nailing 34 or adhesive, and when fixing the side plate 2B, the upper edge of the side plate 28 is attached. is fitted into the edge member 33a.

Similarly, an edge member 33b is attached to the inner surface of the side plate 28, and when the side plate 28 is fixed, the side edge of the main plate 22 is attached to the edge member 33b.
3b.

These edge members 33a and 33b are the roof plate 8 and the side plate 2.
8. This is useful for sealing the joint between the side plate 28 and the main plate 22.

As shown in FIG. 4, a frame 3 is attached to the outer surface of the base of the side plate 28.
5 is abutted against this, an engagement groove 36 is formed on the outer surface of the side frame 5c of the rear window frame 5, and this engagement groove 3
A cylindrical nut 17 with a washer 6 is engaged with the washer 18, and the installation is done with a screw 19 passing through the side plate 28 from the frame 35 side.
The frame 35 is fixed to the side plate 28 by screwing it into the cylinder nut 17.

For installation, connect the frame 35 to the building side structure using the piece 35a.
is formed, and a connecting piece 37 for the same purpose is also formed on the side frame 5c.

The bay window main body 3 configured in this manner is applied to the building from the outdoor side, and the connecting pieces 20, 27, 27, 27, 27, 27, 27, 27, 27, 27, 27 of the rear window frame 5 are attached to the lintel material 39a, the sill material 39b, and the side pillar 39c surrounding the window opening 38. 37. For installation, fix the connecting pieces 16a, 24a = 35a of the frames 16, 24.
Apply.

In this bay window, the roof plate 8 is made of insulating wall material on all four sides, and the base plate 2
2 and the side plates 28, and the window portion is provided with a required heat insulating space 4 between the inside and the outside, so an excellent heat insulating effect is exhibited.

In order to further enhance the heat insulation effect of the bay window, another outer panel 43 may be placed under the base plate 22 to make the base plate structure double, as shown by the imaginary line in FIG.

Reference numeral 44 denotes an engaging portion for attaching the tip of the outer panel 43 to the lower frame 1b, and 45 indicates a fitting used to fix the base of the outer panel 43 to the building side.

Further, in the same figure, the skirt wall 46 attached to the lower surface of the lower frame 1b is provided for the purpose of making the thickness of the lower frame in front of the bay window appear larger and giving a sense of weight.

As detailed above, the present invention has been developed to construct a bay window with excellent heat insulation performance by constructing the four peripheral walls surrounding the front window from heat insulating wall materials, and to fix the bay window itself to the building side. The installation method used is to attach the frame to the bay window body by sandwiching a heat insulating board on the base side and attaching it to the inside and outside, and for these inside and outside installations, the frame is screwed together with bolts and nuts that pass through the heat insulating wall board. Since the frame is not manufactured as one piece, there is less heat transfer between the frames when installing the inside and outside, and therefore when the bay window itself is installed on a building structure, the structure has excellent insulation properties, and when installed inside, there is no risk of condensation on the frame. can be prevented.
