Description

[Detailed Description of the Invention] This invention relates to a window structure provided on a sloped surface of a building, such as a skylight on a sloped roof of a house, a sunroom, a greenhouse, etc.

The proposed window structure on the slope of the building is designed to effectively drain rainwater flowing down from above the window and improve the watertightness of the window.The details of this proposal are explained below with reference to the drawings. .

Figures 1 and 2 show an operable window installed on the sloping roof of a building, and a window frame 5 consisting of upper and lower frames 1°2 and left and right vertical frames 3 and 4 is fixed to the window opening P provided in the roof frame F. Then, a shoji 10 consisting of upper and lower frames 6°7 and left and right vertical frames 8 and 9 is brought into contact with the outside surface of the opening edge of the window frame 5, and the upper frame 6 is hinged to the upper frame 1 of the window frame. 11.11 are connected so that they can be opened and closed.

12 is the glass of the shoji.

Regarding the upper frame 1, the means for fixing the window frame 5 is to fix the base of the connecting plate 13, which has a roughly L-shaped cross section, to the upper surface of the upper frame 1 with screws 35 as shown in the third figure. The connection plate 13
With the rising part 13' extended along the outer surface of the frame F, both ends of the connection plate are welded to the reinforcing bars of the frame, and the connection plates are welded to the lower surface of the lower frame 2 and the left and right sides of the left and right vertical frames 3 and 4. It has a structure in which screwed connecting plates 14 and 15, 16 are welded to the reinforcing bars of the building frame, respectively.

An eaves structure is provided above the upper stile 6 of the shoji 10, and the eaves structure is as follows.

First, on the upper surface of the upper stile 6, there is a channel-shaped groove 17 that opens upward over the entire length of the upper stile.

On the other hand, the draining eave 18 has its upper end fixed to the outer surface of the intermediate portion of the rising portion 13' of the connecting plate 13 with screws 19, and extends linearly over the groove 17 of the upper stile 6. A lower end 20 of the eave protrudes into the groove 17.

In this way, rainwater flowing down the sloped roof surface is guided into the groove 17 of the upper stile along the draining eaves 18, flows through the groove 17, and is discharged onto the roof from the left and right ends of the groove 17. That will happen.

Furthermore, a double outer sole 21 is provided on the outside of the draining eave 18, and the upper end of the outer sole 21 is connected to the connecting plate 18.
It is fixed to the outer surface of the upper end of the rising part 13' with screws 22... and extends linearly to the outside of the upper stile 6, and the upper end of the shielding plate 23 made of an elastic material such as neoprene rubber is attached to the lower end thereof. It is fixed with screws 24, and the tip of the shield plate is elastically pressed against the outdoor side surface of the upper stile 6.

Due to this double eave structure, watertightness is further improved.

25 is the roof frame F, the outer bottom 21, and the connecting plate rising portion 13'
This is mortar that provides a watertight seal between the upper end of the

Note that the left and right opening ends of both soles 18 and 21 are closed with appropriate lids.

A watertight structure is provided between the window frame 5 and the shoji 10,
The watertight structure is as follows.

Attach auxiliary members 26, 27, 28 with chevron-shaped cross sections to the inner faces of the upper frame 1 and left and right vertical frames 3, 4 with screws 29..., 3, respectively.
0..., 31..., and place one side of each auxiliary material on the same plane as the outdoor surface of each frame material, and each of these auxiliary materials 2
Backings 34 are fixed to each of the outdoor surfaces of 6.27, 28 and the frame material 1.3.4, and the outdoor surface of the lower frame 2 so as to form a frame shape, and these backings 3
4 is made of an elastic material such as rubber or synthetic resin and has a roughly L-shaped cross section consisting of a flat part 32 and a rising part 33, and the rising part 33 is located inside the window frame opening. In addition, the flat portion 32 is fixed with the rising portion protruding toward the outside of the room.

Backing 34 arranged in this way... Shoji 10 is placed on the surface
When the shoji top, lower stile 6, 7, and left and right vertical stile 8, 9 are closed, the interior side surfaces of the shoji top, lower stile 6, 7, and left and right vertical stile 8, 9 are placed on the flat part 32 of the backing, as shown in Figure 3.4.5. At the same time, the rising part 33 of the backing protrudes within the frame consisting of the upper and lower frames 6 and 7 and the left and right vertical frames 8 and 9, thereby making the shoji 10
Even if rainwater infiltrates between each stile and the backing 34..., the backing rising portions 33... prevent further infiltration.

Furthermore, in this example, the upper and lower frames 6 and 7 and the backing plane part 32
．． 32, but there is a slight gap d, d between the left and right vertical frames 8, 9 and the backing flat part 32.32, and each frame 6°7.8, 9 and the backing rising part 33. There is also a slight gap d' between...
By doing this, when rainwater flows between the left and right stiles 8 and 9 and the left and right stiles 3 and 4 of the window frame in Fig. 5, the rainwater infiltrates into the gaps d and d by capillary action. This creates a water film that prevents further rainwater from entering.

When condensed water forms on the surface of the glass 12, the condensed water flows down the glass 12, passes through the gap d' between the lower stile 7 and the backing rising portion 33, and flows to the left of the lower stile 7 and the backing rising portion 33 in FIG. The right end is then discharged to the outside through the gap d.

In the present invention, an example is also obtained in which the upper backing 34 is directly fixed to the outside surface of the room at the edge of the window opening provided on the inclined surface without providing a window frame, and the other structure is substantially the same as that of the upper side.

According to the window structure on the slope of the building of this invention, rainwater flowing down the slope falls onto the outdoor side of the upper stile through the outer base, and rainwater leaking from the outer base and other parts is guided into the groove of the upper stile by the draining eaves. The groove allows rainwater to drain left and right, and this double eave structure further improves the watertightness of the window, and the presence of the shield plate allows rainwater to drain from between the outer bottom and the window. It prevents rainwater from entering and does not follow the window when it is opened or closed, causing no hindrance to the opening or closing of the window, and is extremely effective in practice.
