Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is a double window frame that includes an outer window frame, an inner window frame, and a batten that bridges them. , relating to a water-stop structure between an outer window frame and a batten.

0002

[Conventional technology]

In cold regions, double-glazed windows with excellent insulation and high airtightness are often used. However, this double-glazed window is shown in, for example, Japanese Utility Model Publication No. 17499/1983. As shown in Figure 2, external window frames made of metal such as aluminum are installed on the exterior wall facing outdoors. On the inside, an inner window frame made of synthetic resin, which has low thermal conductivity, is lightweight, and is inexpensive, is attached to the outer window frame. It is assembled into a frame-shaped structural material, and glass shoji, Japanese shoji, etc. are assembled on the outer and inner window frames. It is common that it is made to absorb.

0003 In such a double window frame, the bare skin (structure) exposed between the outer window frame and the inner window frame In order to hide the material surface), a synthetic resin such as vinyl chloride is used to bridge the material. A batten board is often arranged.

0004

[Problem that the idea aims to solve]

A double window frame with battens arranged to bridge the outer window frame and the inner window frame as described above. For example, Japanese Patent Laid-Open Publication No. 137387/1987 etc. As shown, push the outdoor end of the batten against the angle of the indoor end of the outer window frame. Glue them together to the surface of the structural material, or under the angle of the outer window frame. Some methods are adopted, such as laying it on the side and tightening it with screws together with the external window frame to fix it to the structural material. It is being

[0005] However, in this arrangement of the battens, condensed water can enter between the battens and the structural members. The battens may peel off and become uneven, resulting in an unsightly appearance, or condensation water may form. They can enter the wall through the battens and cause the cloth to peel off and the wall to become dirty. Problems may arise. In view of this, the present invention prevents peeling of battens and staining of walls due to condensed water. The purpose of the present invention is to provide a water-stop structure for a double-glazed window frame.

[0006]

[Means to solve the problem]

In order to achieve the above-mentioned purpose, the fixing structure of the inner window frame according to the present invention is It is assembled into a metal outer window frame and a frame-shaped structural member placed indoors from this outer window frame. The above-mentioned inner window frame made of synthetic resin is attached so as to bridge the above-mentioned outer window frame and inner window frame. In a double window frame equipped with a synthetic resin batten placed on the structural material, the batten is A tongue-shaped water stopper made of soft synthetic resin is protruded from the upper surface of the outdoor end of the The indoor end of the outer window frame is placed over the batten so as to press against water particles. It is characterized by.

[0007]

[Effect]

In the fixing structure of the inner window frame according to the present invention configured as described above, The indoor end of the outer window frame is placed so as to press against the tongue-shaped water stopper that protrudes from the window frame. Therefore, the tongue-shaped water stopper prevents condensed water from entering between the batten and the outer window frame. be done. Therefore, peeling of the batten, staining of the wall, etc. can be effectively avoided.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view showing the main parts of an embodiment of the waterproof structure for a double-panel window frame according to the present invention. FIG. 2 is a vertical cross-sectional view showing the schematic structure of a double-glazed window to which this method is applied. In Fig. 2, the double-glazed window to which this embodiment is applied has an opening on the outer wall facing outdoors. An external window frame 11 made of metal such as Lumi is assembled, and on the indoor side, it is assembled into a picture frame shape. The structural material 17 made of wood that is assembled into the outer window frame 11 has low thermal conductivity and is lightweight. Inner window frame 23 made of inexpensive synthetic resin is assembled. The outer window frame 11 is made of aluminum A pair of glass shoji doors 13 consisting of a frame 12 and a glass plate 15 fitted into it It is built in a sliding type, and the inner window frame 23 has a frame 19 made of synthetic resin such as vinyl chloride. and a synthetic resin board fitted into it with excellent heat insulation and lighting (also a substitute for Japanese paper) Therefore, for example, both sides of hard acrylic foam can be specially treated with resin containing glass cloth. A Japanese shoji door 20 consisting of a newly constructed shoji door 21 is installed in a sliding type.

[0009] A relatively hard material is placed on the structural member 17 to bridge the outer window frame 11 and the inner window frame 23. A batten 30 made of synthetic resin is arranged. The indoor end of this batten 30 is an inner window. It is laid on the bottom side of the outdoor end of the frame 23, and bent downward of the batten 30. The top surface of the outdoor end extending to the outside end is made of relatively soft synthetic resin such as vinyl chloride. Two tongue-shaped water stop pieces 32 are parallel to each other, and their bases are integrally connected to the battens 30. It is installed protrudingly.

0010 Then, the indoor end of the outer window frame 11 is shaped so as to press the tongue-shaped water stopper piece 32. The angle portion formed is placed on the batten 30, and the screw 34 is placed on the roof of the outer window frame 11. It is screwed into the structural member 17 by passing through the inner end and the outdoor end of the batten 30. child The screws 34 are used to fix the outer window frame 11 and the batten 30 and to fix the indoor end of the outer window frame 11 in a tongue-like manner. It serves to press against the water pieces 32. Note that this role is for connections other than the screw 34. Of course, other means may also be used.

[0011] In the waterproof structure of the double window frame of this embodiment configured as described above, the battens 3 The indoor end of the outer window frame is covered so as to press the tongue-shaped water stopper piece 32 protruding above the outer window frame. Since the tongue-shaped water stopper piece 32 makes the space between the batten and the outer window frame airtight, The tongue-shaped water stopper piece 32 prevents condensed water from entering this area. Therefore, Peeling of the batten 30 from the structural material 17 and staining of the wall portion are effectively avoided.

0012

[Effect of the idea]

As is clear from the above explanation, the water-stopping structure of the double-panel window frame according to the present invention allows the eyes to The indoor end of the outer window frame is placed so as to press against the tongue-shaped water stopper protruding from the board. Therefore, condensation water that tries to enter between the batten and the outer window frame is blocked by the tongue-shaped water stopper. To be reliably prevented and, as a result, to effectively avoid peeling of the battens and staining of walls, etc. I can do it.
