Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a structure of a roof material for a bay window provided in a building.

[Prior Art] Conventionally, as this type of bay window roof material, various types such as a type having a single inclined surface and a type having a plurality of inclined surfaces have been used. Is entirely formed of an aluminum plate material or an aluminum cast body, or a glass plate is incorporated in a frame made of an aluminum material.

[Problems to be Solved by the Invention] However, in any of the conventional roofing materials for bay windows, the skylight is not attached, and it is not possible to perform ventilation or daylighting in this roofing material portion. This is because if you try to attach a skylight to the roofing material, the whole product will not fit properly, and you will need to provide an opening to install the skylight, and you must also provide a separate means to prevent water leakage from the opening. This is because there are many problems such as difficulty in opening the opening because a heat insulating material for preventing dew condensation is generally attached to the lower portion of the roof material.

The purpose of the present invention is not only to install a skylight on the roofing material main body for lighting and ventilation, but also to prevent water leakage from the installation part of the skylight. An object of the present invention is to provide a roof material for a bay window that can reliably support a skylight.

[Means for Solving the Problems] Therefore, in order to achieve the above-mentioned object, the present invention provides a roof material main body which is attached to a wall and covers the upper part of a bay window with an opening for communicating the inside and the outside thereof, and An annular mounting portion is provided on the peripheral portion so as to project upward, and a flat portion extending inward is provided at an upper end portion of the annular mounting portion so as to cover the mounting portion and the flat portion and to overlap the flat portion. The gist of the invention is to provide a bayonet roofing material in which a lower surface of an annular pedestal frame is attached to and supported so that an upper surface corresponding to a flat portion of the pedestal frame and a lower surface of a skylight are in surface contact with each other.

Then, it is preferable that the roof material main body and the mounting portion are integrally formed by an aluminum cast body.

[Operation] The roofing material main body is provided with an opening communicating with the inside and outside thereof, and further, a ring-shaped mounting portion is provided so as to project upward at the peripheral edge portion of the opening, and further, an inward direction is provided at the upper end of the ring-shaped mounting portion. A flat portion extending to the flat portion is provided, and the lower surface of the annular pedestal frame is attached so as to cover the attachment portion and the flat portion and to overlap the flat portion. The upper surface corresponding to the flat portion of the pedestal frame and the lower surface of the skylight are supported so as to be in surface contact with each other. Therefore, it is possible to not only perform daylighting and ventilation, but also to prevent water leakage from the attachment portion of the skylight, and to reliably support the skylight.

Further, since the roof material main body and the mounting portion are integrally formed by the aluminum cast body, the number of parts and the number of assembling steps are smaller than in the case where the both are formed by separate members, and further, the mounting portion and the roof material. There is no gap between the main body and the unit due to mounting, and there is no water leakage at this part.

[Embodiment] An embodiment embodying the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 2, between the pillar 2 provided on the wall 1 of the building and the upper frame 3 arranged at a position separated from the wall 1 by the aluminum cast body. A molded roofing material body 4 is installed. This roofing material body 4 is the second, the third
As shown in the figure, the front part 4a has a substantially rectangular shape that is long on the left and right (upper and lower sides in FIG. 3), and is formed to be lower toward the front side.
And side surfaces 4b that are integrally formed on both the left and right sides and that are inclined so as to be lower toward the front right or the front left.

As shown in FIGS. 1 and 3, vertical portions 4c are formed by bending on the lower end edges of the front surface portion 4a and the left and right side surface portions 4b.
4c is attached to the bracket 5 of the upper frame 3. Also,
A bent portion 4d having an L-shaped cross section is integrally formed at the rear end edges of the front surface portion 4a and the left and right side surface portions 4b, and the bent portion 4d is fixed to the column 2 by a plurality of wood screws 6. There is.

A rectangular opening 7 that communicates the inside and outside of the front portion 4a is formed in a substantially central portion of the front portion 4a of the roofing material main body 4, and a peripheral edge portion thereof is formed so as to be orthogonal to the front portion 4a. A rectangular ring-shaped mounting portion 8 which projects upward and has a low height is integrally formed. Then, in the roofing material configured as described above, the pedestal frame 9 is fixed by the screw 10 to the bent portion 8a which is a flat portion bent inward at the upper end of the mounting portion 8. .

At the rear end of the pedestal frame 9, a rear end of a skylight 11 capable of opening and closing the opening 7 of the roofing material body 4 is rotatably supported by a shaft 12. In the upper half of the skylight 11, a multi-layered glass 15 is arranged, and in the lower half, a single glass 13 is arranged apart from each other.
14 is installed. With this blind 14, it is possible to adjust the angle of the slats. As shown in FIG. 4, when the skylight 11 is closed, the skylight 11 is closed.
The lower half part of the lower part enters the pedestal frame 9 to close the opening part 7.

As described above, in this embodiment, the roofing material main body 4 having a plurality of inclined portions is integrally formed by the aluminum casting, and the opening portion 7 is provided in the front surface portion 4a which constitutes one inclined portion, and the opening portion is formed. Since the mounting portion 8 in the form of a square ring is integrally formed on the peripheral edge portion of 7, the skylight 11 can be mounted on the mounting portion 8 via the pedestal frame 9.

In this embodiment, since the skylight 11 is attached to the pedestal frame 9 so as to be openable and closable, ventilation can be performed by opening the skylight 11. In addition, the double glazing 15 and the glass on the skylight 11.
Since 13 is incorporated, it is possible to perform daylighting through these glasses 13 and 15, and further, by adjusting the slat angle of the blind 14 mounted in the skylight 11, the amount of daylighting into the bay window is changed. You can also

By the way, when a commonly used double sash is applied to the skylight 11, the glass surface may be contaminated due to dew condensation depending on the conditions, but in this embodiment, the portion of the skylight 11 that is directly exposed to the outside air. Since the multi-layer glass 15 is arranged in the upper half part, it is possible to prevent the occurrence of dew condensation and the stain on the glass surface due to the dew condensation.

When the opening 7 is closed by the lower half of the skylight 11 (see FIG. 4), even if rainwater or the like falls on the roofing material body 4 or the skylight 11, an annular mounting portion 8 and a pedestal frame 9 are formed. It is blocked by and is prevented from entering the opening 7.

In the roof material of the present embodiment, since the mounting portion 8 is integrally formed with the roof material main body 4 as described above, the number of parts and the number of assembling steps can be smaller than those of the roof material formed by separate members. Not only is it possible to reduce the manufacturing cost, but there is no gap between the mounting portion 8 and the roofing material body 4 due to mounting, and watertightness is further improved.

The present invention is not limited to the configuration of the above embodiment,
For example, attaching the skylight 11 to the pedestal frame 9 so as not to rotate,
Mounted so that it can slide laterally, or skylight 11
The whole structure can be lifted so that it can be lifted from the pedestal frame 9, and the shape of the opening 7 and the mounting portion 8 can be changed as appropriate without departing from the spirit of the invention. You can also do it.

Further, the mounting portion 8 may be configured by a member different from the roofing material main body 4.

Further, the pedestal frame 9 may be formed of ceramics which is less likely to cause dew condensation, and may be attached to the roofing material main body 4 in a structure as shown in FIG. That is, the mounting cylinder portion 16 may be formed on the inner surface of the roof material main body 4, and the pedestal frame 9 may be fixed to the roof material main body 4 by the bolts 18 inserted into the holes 17 provided in the inner bottom portion thereof. In this case, it is preferable to fill the mounting tube portion 16 with the sealing material 19 after tightening with the bolts 18. In the embodiment shown in FIG. 5, the connecting structure between the mounting portion 8 and the pedestal frame 9 is the same.

It is also possible to embody the present invention in a roofing material having a single inclined surface.

[Effects of the Invention] As described in detail above, according to the present invention, not only can a roof window be attached to the roofing material main body to perform daylighting and ventilation, but also water can be supplied from the attachment portion of the skylight. It is possible to prevent the occurrence of leakage, and it is possible to reliably support the skylight.

Further, since the roof material main body and the mounting portion are integrally formed of an aluminum cast body, the number of parts and the number of assembling steps can be reduced as compared with the case where the both are formed by separate members, and further, between the mounting portion and the roof material main body. It also has the effect of preventing water leakage.
