Description

[Detailed Description of the Invention] The present invention relates to a heat insulating sash frame material that constitutes a heat insulating sash frame in a fitted window, a casement window, a sliding window, a multiple sash, etc.

The conventionally known heat-insulating sash frame is a frame made of heat-insulating sash frame material in the shape of a quadrangular frame, and the outdoor-side member is made of metal such as aluminum, and the indoor-side member is made of synthetic material. For example, a device made of a material with excellent heat insulation properties such as resin, and having an indoor side member and an outdoor side member connected in the widthwise direction is known, for example, from Japanese Utility Model Application Publication No. 51-133115.

However, with this conventional structure, the insulation sash frame is an internal installation type that is attached to the inner circumferential surface of the frame for mounting the sash frame that forms the window opening. No special measures are required for rain protection, connection strength, and heat insulation performance of the connecting part with the outside member, but this is an external or semi-external type in which the insulating sash frame protrudes from the frame to which the sash frame is attached to the outdoor side. In this case, the connecting portion between the indoor side member and the outdoor side member is exposed to the outside, so special improvements are required in terms of rain protection and strength of the connecting portion.

The present invention has been devised in response to the related art, and its purpose is to provide insulation for a heat-insulating sash frame that is attached to a frame for mounting a sash frame that has an opening and protrudes outward from the frame.

Further, the surface of each of the indoor side members that is exposed to the outside is coated with a coating material F such as a paint having good weather resistance.

That is, in the upper frame a, the lower wall 4 of the indoor member 2 and a portion of the lower wall 12 of the outdoor member 10 are coated with a paint having good weather resistance.

As a result, the surface of the indoor member 2 of the upper frame that is exposed to the outside is covered with the weather-resistant coating material F, so that the synthetic resin outer wall 4 is prevented from deteriorating due to sunlight or other irradiation, making it weather-resistant. Good upper frame a
becomes. In addition, the covering material F also penetrates into the connection part 2 between the lower wall 4 and the lower wall 12 (that is, the connection part between the indoor and outer members 1 and 10) and covers the connection part 2, so that rainwater etc. can leak from the connection part 2. There is no penetration and the sealing effect is improved.

In addition, in the lower frame b, the upper wall 22 of the indoor side member 20 and a part of the upper wall 31 of the outdoor side member 30 are covered, and in the vertical frame c, the inner wall 43 of the indoor side member 40 and the upper wall 31 of the outdoor side member 50 are covered.

03, and in the vertical stile j, the inner wall 83 and outer wall 84 of the indoor member 80 and a part of the outer wall 113 of the outdoor member 110 are covered.

This improves the weather resistance of each indoor member, and improves the sealing effect of the joints E, H, H, J, and I between each indoor member and the outdoor member.

In addition, in the indoor side member 120 of the mullion d, the inside wall 1
23, both side walls 124, 125 and outdoor side member 13
Parts of both side walls 133 and 134 of the indoor side member 120 are coated, thereby improving the weather resistance of the indoor member 120 and improving the sealing effect of the connecting portions 1 and 2.

As mentioned above, each frame a, b, c and each frame h, i,
j is indoor side members 1 and 2 made of synthetic resin with excellent heat insulation properties
0, 40, 60, 70, 80 and the metal outdoor side members 10, 30, 50, 90, 100, 110 are directly connected, so it has excellent heat insulation properties and is easy to assemble. This makes it easy to connect, and also increases the connection strength to provide a stable connection state.

In addition, the exterior surfaces of the indoor side members 1, 20, 40, 60, 70, 80 of each frame a, b, c and each frame h, i, j are coated with a weather-resistant coating material F. Because of this, it has good weather resistance and is suitable for outdoor side members 10,30,50,90,100,11.
It is possible to improve the sealing effect of the connecting parts D, E, H, G, and C to prevent rainwater from entering the inside.

In addition, the connection part i on the outer circumference side of each frame a, b, c,
B and C are extension pieces 1 of the outdoor side members 10, 30, and 50.
1', 32', 51' as indoor side members 1, 20, 40
Since the connecting portions A, B, and C are located close to the frame D, the thickness of the exterior material E is approximately constant and the frames a, b, Even if the width of c becomes wider, the connecting parts A, B, and C on the outer side can be covered with the exterior material E, and rainwater, etc. does not infiltrate into the interior from the connecting parts A, B, and C, resulting in excellent watertightness. It becomes something.

In other words, if the structure is such that the indoor side member and the outdoor side member are simply abutted and connected, the connection part will be connected to the frame D.
The location will be more remote. For this reason, if the width of the frame is widened, the connecting part will be located quite far away from the main frame D, so if the thickness of the exterior material E is constant, the connecting part cannot be covered with the exterior material E, and rainwater etc. will get inside. Water will seep in and the watertightness will deteriorate.

In addition, to connect frames a, b, and c, each extension piece 1
1', 32', 51' are formed in an outwardly expanded state, and the indoor side members 1, 20, 40 and the outdoor side member 1 are formed.
Extension piece 1 when temporarily connected with 0, 30, 50
1', 32', and 51' are caulked inward.

Since the present invention is configured as described above, it has the following effects.

The extension piece covers and protects the fitting and locking part of the indoor member from the outside, and its tip penetrates further into the indoor side than the surface of the exterior material around the insulation sash frame. Since the caulking part around the sash frame enters the indoor side and is located, there is no risk that rainwater, etc. that runs down the exterior material will enter from the fitting and locking part of the indoor side member, and the connection part can be closed from the rain. Get better.

In addition, caulking material can be provided between the metal extension piece and the exterior material, and the caulking material around the insulation sash frame material can be the same as the conventional metal sash frame material, and synthetic resin sash frame material can be used. There is also the effect that there is no need to use a special frame.

In addition, since the fitting and locking parts of the indoor side member and the outdoor side member are offset toward the outdoor side from the center of the expected width of the insulating sash frame material, the expected width of the indoor side member is wider than the expected width of the outdoor side member. As the length of the insulation sash frame material increases, the area that can be covered by the indoor member made of materials with good insulation properties becomes large, so even if the insulation sash frame material used for the external type insulation sash frame material is used, it is necessary to obtain sufficient insulation effect. If you increase the area occupied by indoor side members made of synthetic resin etc. in external or semi-external type insulation sash frames, the frame material will inevitably become weaker due to its material quality. In addition to being reinforced by the pieces, it also protects the outer circumferential side of the indoor member from being directly exposed to the outdoors, and also protects and reinforces the connection and fixation by the fitting and locking portion of the indoor member. Therefore, sufficient frame strength can be guaranteed even though the area occupied by the indoor side member is large in the external type heat insulating sash frame.
