Description

The present invention relates to a combined structure of a window device in which an outer sash and an inner sash are built in the window frame, respectively.

Window devices are installed at the openings of the building frame for the purpose of daylighting and ventilation. The frame material of the window frame and the frame material for the window shoji that constitute such a window device are generally made of an aluminum alloy. However, since aluminum alloy has high thermal conductivity, the temperature of the surface of the frame material and the frame material on the indoor side becomes close to the temperature of the outside air, which may impair the cooling and heating effect of the room as it is, and also in winter. Condensation may form on the floor and stain the floor and curtains.

In view of such circumstances, Japanese Patent Application Laid-Open No. 10-184199 discloses a structure in which a frame material or a frame material is formed by connecting an outdoor frame made of an aluminum alloy and an indoor frame made of a synthetic resin. Has been done. In the first example of such a conventional structure, since the thermal conductivity of the synthetic resin constituting the indoor frame is low, the temperature of the indoor frame can be easily kept constant regardless of the temperature of the outside air. Therefore, the air-conditioning effect in the room can be improved, and the occurrence of dew condensation can be prevented. However, in the first example of such a conventional structure, the durability and weather resistance are lower than those in the case where the entire frame material and frame material are made of aluminum alloy. Further, for example, when attaching the frame of the window device, it is necessary to consider the influence of sparks and scratches due to welding.

In view of such circumstances, Japanese Patent Application Laid-Open No. 10-196228 describes a frame material and a frame material to be connected to an aluminum alloy outdoor frame and an indoor frame, and these outdoor frames and an indoor frame. A structure composed of a heat insulating material made of synthetic resin is disclosed. In the second example of such a conventional structure, since a heat insulating material made of synthetic resin having a low thermal conductivity exists between the outdoor frame and the indoor frame, both the outdoor frame and the indoor frame are connected to each other. The amount of heat transfer between them is reduced. Therefore, it is possible to easily keep the temperature of the indoor frame constant regardless of the temperature of the outside air. Therefore, the air-conditioning effect in the room can be improved and the occurrence of dew condensation can be prevented. In addition, durability and weather resistance can be improved as compared with the case where the indoor frame is made of synthetic resin. Further, even when the window device is attached to the frame, consideration for the influence of sparks and scratches due to welding is reduced.

By the way, as in the second example of the above-mentioned conventional structure, the outer sash that constitutes the outer shoji is a heat insulating stile in which the outdoor frame and the indoor frame made of aluminum alloy are connected by a heat insulating material made of synthetic resin, respectively. Even in this case, it is difficult to prevent the entire indoor frame from being exposed to the outside. For this reason, it becomes difficult to improve the heat insulating performance as compared with the case where other stile materials are used as heat insulating stiles. In recent years, the height of buildings such as buildings and condominiums has been increasing, and the wind pressure resistance required for the stiles that make up the shoji is increasing. No, the wind pressure resistance is lower than that of a non-insulated frame made entirely of aluminum alloy. For this reason, it may be advantageous in designing the window device to use a non-insulating stile that can increase the wind pressure resistance strength, rather than using a heat insulating stile, for the outer sash that constitutes the external shoji. However, if the outside sill is simply a non-insulated stile, part of the outside sill cooled by the outside air will be exposed indoors, causing a drop in indoor temperature or condensation. there's a possibility that.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to ensure both the strength of the outer mating stile constituting the external shoji and the heat insulating performance of the window device. It is to realize a combination structure.

The combined structure of the window device of the present invention comprises an outer sash that constitutes the outer sash and an inner sash that constitutes the inner sash, which are arranged so as to face each other in the out-of-plane direction in a closed state of the outer sash and the inner sash. Equipped with a stile.
The inner serving stile is a heat insulating stile, and the outdoor inner serving stile arranged on the outdoor side and the indoor inner serving stile arranged on the indoor side are arranged in the out-of-plane direction via a heat insulating material. It is connected.
The outer mating stile is a non-insulating stile that is entirely made of metal and does not have a heat insulating material, and its interior side surface is covered with a synthetic resin cover in the vertical direction. Further, between the portion of the cover protruding in-plane from the outer mating stile and the glass panel constituting the outer sash, a sealing material (integrally molded product with the cover, separate from the cover). (Including packing material, sealing material to be filled between the cover and the glass panel, etc.) is provided.

In the present invention, for example, a drainage channel can be provided in the vertical direction between the indoor side surface of the outer mating stile and the outdoor side surface of the cover.

In the present invention, for example, the sealing material can be provided integrally with the cover.

Alternatively, the sealing material may be provided separately from the cover.

In the present invention, for example, the end on one side in the in-plane direction corresponding to the side where the closed sash is located is positioned on one side in the in-plane direction with the inner sash rather than the outer stile. Can be done.

In the present invention, for example, an opening opened in the in-plane direction is provided in a part of the cover, an auxiliary metal fitting for fixing the crescent receiver is inserted inside the opening, and the auxiliary metal fitting is inserted into the cover. It can be screwed with a fixing screw through which a metal grain plate fixed to the indoor side of the room is inserted.

In the present invention, for example, the airtight material provided on the outdoor side surface of the inner mating stile can be brought into contact with the indoor side surface of the panel.

In the present invention, the outdoor side inner combination stile, the indoor side inner combination stile, and the outer combination stile can each be made of an aluminum alloy.
Examples of the aluminum alloy include A6063S-T5 material (JIS H 4100), that is, 0.20 to 0.6% by weight of Si, 0.35% by weight or less of Fe, and 0.10% by weight or less of Cu.

Those containing the following Ti and unavoidable impurities having an individual content of 0.05% by weight or less and a total of 0.15% by weight or less and the balance being Al can be preferably used.
Further, in the present invention, the heat insulating material may be made of a synthetic resin such as polyamide 6 (nylon 6) and has a strip shape (plate shape).

According to the present invention, it is possible to secure both the strength of the outer mating stile constituting the external shoji and the heat insulating performance of the window device.

The heat insulating material 8d1 (8d2) is provided at a position facing the internal sash 4. In addition, the heat insulating materials 8a1 (8a2) and 8b1 (8b2) constituting the upper frame 5 and the lower frame 6 are provided with respect to the heat insulating material 8c1 (8c2) of the vertical frame 7a and the heat insulating material 8d1 (8d2) of the vertical frame 7b. They are provided in the center of the out-of-plane direction so that they are aligned in the out-of-plane direction. Therefore, in this example, each frame material existing on the outdoor side of the frame-side heat insulating line 9 (outdoor outer frame 10, outdoor lower frame 18, first chamber outer vertical frame 36, second chamber outer vertical frame 39). Each frame material (indoor side upper frame 11, indoor side lower frame 19, first room) existing on the indoor side of the frame side heat insulating line 9 even when the temperature of the air is close to the temperature of the outside air (for example, cooled). It is possible to effectively prevent the temperature of the inner vertical frame 37 and the second indoor vertical frame 40) from changing according to the temperature of the outside air. For this reason, for example, when the heat insulating line is formed only in the portion of the window frame that is consistent with the outer sash in the out-of-plane direction, the entire sash is located on the indoor side of the heat insulating line.
