BACKGROUND OF THE INVENTION
The present invention relates to a method for manufacturing a window frame of a wooden sash window.
[0002]
[Prior art]
Insulated aluminum sashes have good heat insulation and dew proofing performance, so they have been widely used instead of non-insulated aluminum sashes. On the other hand, in a wooden sash, if water accumulates in the glass groove of the lower sash and lower frame of the sash, it causes corrosion, so that a technique for preventing the retention of rain and condensed water is known. For example, it is a technique of Unexamined-Japanese-Patent No. 8-333966. This prior art wooden sash has a drainage hole in the vertical direction below the window glass of the lower window frame, and even if rain or condensation water flows into the glass groove in the window frame, it flows out of the drainage hole and the water stays I was prevented from doing it.
[0003]
[Problems to be solved by the invention]
However, the conventional aluminum sash has an environmental problem because it consumes a large amount of energy when manufacturing aluminum. In addition, the aluminum sash has an artificial exterior appearance. In particular, when the aluminum sash is attached to a wooden house, there is a problem in that the harmony between the metal and the wood is poor and the design is inferior. In addition, even with conventional wooden sashes, even if it prevents rain and condensation water from staying in the window frame, the water collected in the close contact area will not dry quickly, and it will be corroded by decaying bacteria for a long period of time. However, the sash function was deteriorated. Thus, although antiseptic treatment is effective and necessary, there is a problem that environmentally strong chemicals cannot be used.

The window frame 35 is made of a laminated material of plate material and a synthetic resin, and an unnecessary portion is cut to form a window frame of a desired shape. In this embodiment, the portion where the peripheral edge of the window glass 6 is in contact is condensed. When rainwater is generated, water drops fall and soak, and the portion of the tree rots. Therefore, a synthetic resin is provided at the contact portion to prevent rot due to condensation. That is, as shown in FIG. 5 (a), a cross section is obtained by laminating a wooden part 35g, which is a laminated material obtained by laminating a plurality of plate members 35j, 35j,... A rectangular block member 35 'is formed. Then, as shown in FIG. 5 (b), portions 70, 71, and 72 that do not require the block member 35 ', that is, the portion 70 into which the window glass 6 is fitted, and the portion 71 into which the window frame aluminum clad 36 is fitted. 72 is removed using a cutting tool. In this way, a resin portion 35k having a substantially L shape in side view is formed in accordance with the position of the concave portion 35a into which the lower end portion of the window glass 6 is fitted.
[0017]
With this configuration, water drops fall along the window surface and a part of the water enters the concave portion 35a and accumulates on the resin portion 35k. However, since the water does not penetrate into the wooden portion 35g, the wooden portion 35g is rotted. The durability can be improved. The accumulated water can be drained from a drain hole 35h provided in the lower window frame, and the remaining water is evaporated and dried as the temperature rises. It should be noted that the resin portion 35k is made inconspicuous by making the resin portion 35k thin, and can be made to appear almost made of wood. In this way, the window frame is formed by scraping from the block where the laminated material and resin are pasted, so it can be easily made into a resin compared to the conventional process of forming the glass groove bottom and pasting the resin, and deterioration due to decay Can be prevented. In addition, the resin part 35k serves as a core material to increase the strength of the block member 35 ', and the resin part 35k and the wood part 35g are integrated to prevent water from penetrating into the gap and prevent deterioration due to decay. It can be done. Also, compared to the case where the resin part and the wood part are attached later, the work efficiency at the time of manufacture is good, and the block member 35 'is made by sticking the wood together, so that an inexpensive material can be used and the cost can be kept low. Can do. Moreover, environmental deterioration can also be prevented by comprising synthetic resin with synthetic resins which do not contain chlorine, such as a styrene resin.
