Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to window openings in unit baths.

[Conventional technology]

FIG. 1 shows the structure of a window opening in a conventional unit bath. In the figure, 1 is a building wall,
2 is a window frame member, and 3 is a window frame. The window frame 3 is fitted into the mounting opening 5 surrounded by the unit wall 4 as shown in FIG. 2 until the front flange 3a contacts the unit wall 4, and the rear flange 3b is fixed to the window frame member 2 with screws or the like. However, because the unit wall 4 is assembled with a gap between the building wall 1 during construction and is only backed by the reinforcing rib 6 on the back of the unit wall, the front flange 3a may be damaged due to construction errors. A gap often occurs between the unit wall 4 and the unit wall 4, causing water leakage, and the unit wall 4 and reinforcing rib 6 may deteriorate over time.
This has the disadvantage that the waterproof properties and appearance deteriorate due to the adhesive coming off, and there is also the disadvantage that it bends when pressed against the unit wall, giving people a sense of instability.

[Means for solving problems]

This invention was made to eliminate the above-mentioned conventional drawbacks, and its configuration will be explained below based on one embodiment of this invention.

In Fig. 3, 7 is a U-shaped metal fitting for the front leg 7a.
A boss portion 8 with a screw hole is fixed outwardly,
A hole 7b communicating with this screw hole is provided.
The metal fitting 7 is attached to the rear leg 7 with the screw hole facing the building wall 1.
c is supported by fixing it to the back surface of the unit wall 4 near the mounting opening 5 with rivets 10 or the like. The metal fittings 7 are normally attached to the unit wall 4 above and below the mounting opening 5, two on each side.

Reference numeral 11 is a spacer bolt that is screwed into the boss part 8 with the head facing toward the building wall 1 and the threaded part facing inside the metal fitting 7.

In this configuration, the unit bath is assembled and installed so that the unit wall 4 is positioned with a gap slightly narrower than a predetermined gap from the building wall 1. Next, the head of the spacer bolt 11 is brought into contact with the building wall 1 and rotated further, thereby expanding the gap between the unit wall 4 and the building wall 1 so that the unit wall 4 is supported by the spacer bolt 11. to prevent the unit wall 4 from bending unnecessarily. and,
The rear flange 3b connects the front marnge 3a of the window frame 3 fixed to the window frame member 2 near the window opening of the building wall 1, and the front marnge 3a of the window frame 3 is fixed to the window frame member 2 near the mounting opening 5 of the unit wall 4 stably supported by the spacer bolts 11. The window is placed in close contact with the inside of the window, creating a window that does not leak water as a whole.

Note that the window frame 3 may be divided into several parts so that they can be connected at the time of construction, or may be configured to also serve as the window frame member 2.

[Effect of idea]

As described above, according to this invention, a spacer bolt is interposed between the building wall and the unit wall, and by rotating and rubbing the spacer bolt, the unit wall is stably supported by the spacer bolt, and the unit wall and window frame are The flanges of the unit should be brought into close contact to improve waterproofness and airtightness.Since the unit wall is supported by the spacer bolts, there will be no unsteady feeling even when pushed by hand, giving people a sense of instability. I have nothing to give.

According to this invention, the head of the spacer bolt is brought into contact with the building wall, so the building wall is less likely to be damaged and construction is easier.
