Abstract

(57) [Abstract] [Purpose] Even if the area of the glass panel 3 is widened, the manufacturing cost of the skylight and the increase in weight are prevented. [Structure] Among a plurality of frame members constituting a window frame, a support frame member 9 is bridged between the middle portions of two frame members which are parallel to each other.
The support frame member 9 supports the lower surface of the intermediate portion of the glass panel 3. Since the supporting frame member 9 is not exposed on the upper surface of the glass panel 3, it does not deteriorate the design when the skylight is viewed from above.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The glass panel supporting device for a skylight according to the present invention is incorporated in a skylight for lighting called a top light to support the lower surface of a glass panel having a large area.

[0002]

[Prior art]

 For example, when using the space between a pair of adjacent buildings as a terrace, a skylight called a toplight is installed between the walls of this pair of buildings. As shown in FIG. 2, this skylight is constructed by supporting four sides of a plurality of glass panels 3 and 3 with a window frame 2 formed by combining a plurality of frame members 1a, 1b, 1c and 1d. ing.

As shown in FIG. 3, each of the frame members 1 a, 1 b, 1 c, 1 d has a main portion 4 a, 4 b whose ends are connected to each other, and screws 6, 6 for connecting the main portions 4 a, 4 b. It consists of sub-parts 5a, 5b joined together. The peripheral portions of the glass panels 3 and 3 are supported by the window frame 2 by being sandwiched between the main portions 4a and 4b and the sub portions 5a and 5b. Packing 7, 7 is provided between the lower surface outer peripheral portion of each glass panel 3, 3 and each main portion 4a, 4b, and the upper surface outer peripheral portion of each glass panel 3, 3 and each sub portion 5a, 5b. Caulking materials 8 and 8 are provided between them to keep each part watertight.

[Problems to be solved by the device]

 The glass panel supporting device for a skylight of the present invention prevents the manufacturing cost and weight of the skylight from increasing even when the area of the glass panel is increased.

In order to clean the design when the skylight is viewed from above, one glass panel having a large area is used as the glass panel 3 and a frame material for partitioning adjacent glass panels 3 and 3 from each other. It is preferable to reduce the number of 1b and 1b.

On the other hand, when the area of each glass panel 3, 3 is widened, the amount of deflection of each glass panel 3, 3 becomes large. In addition to its own weight, each glass panel 3 and 3 bends due to the pressure difference between the upper and lower surfaces of the skylight, so when the area is wide, each glass panel 3, It is necessary to provide the glass panel 3 with sufficient rigidity to prevent the glass panels 3 and 3 from being damaged. Therefore, conventionally, when the glass panels 3 and 3 having a large area are used, the thickness of the glass panels 3 and 3 is increased to improve the rigidity of the glass panels 3 and 3.

However, when the thickness of the glass panels 3 and 3 is increased, the weight of each glass panel 3 and 3 is increased, and the frame members 1a and 1b for supporting the glass panels 3 and 3 are It is necessary to use durable materials as 1c and 1d. As a result, not only the weight of the glass panels 3 and 3, but also the weight of the window frame 2 is considerably increased, and the weight of the entire skylight is considerably increased. When the weight of the skylight increases, the strength of the part that supports the skylight must be improved. As a result, the manufacturing cost of the skylight portion is considerably increased.

The glass panel supporting device for a skylight of the present invention was devised in view of the above circumstances.

[0009]

[Means for Solving the Problems]

 The glass panel supporting device for a skylight of the present invention is made by combining a glass panel and a plurality of frame members, and a window frame that supports the four sides of the glass panel and the above-mentioned plurality of window frames that constitute the window frame. The frame member is provided with a support frame member which is hung between the middles of two parallel frame members to support the lower surface of the middle portion of the glass panel.

[0010]

[Action]

 In the case of the glass panel supporting device for a skylight of the present invention configured as described above, since the supporting frame member supports the lower surface of the middle portion of the glass panel, a glass panel having a large area and a small thickness is used. However, this glass panel does not bend significantly and damage to this glass panel can be prevented.

Further, since the supporting frame member is not exposed on the upper surface of the glass panel, the design when the skylight is viewed from above is neat.

[0012]

【Example】

 FIG. 1 shows an embodiment of the present invention. The skylight in which the supporting device of the present invention is incorporated is a window frame 2 formed by combining a plurality of frame members 1a and 1b as shown in FIG. It is constructed by supporting the three sides of three and three.

Of the plurality of frame members 1a, 1b, 1c, 1d forming the window frame 2, two frame members 1d, 1d (see FIG. 2) arranged in an inclined direction and parallel to each other are provided. A support frame member 9 is bridged between the intermediate portions. In the case of the illustrated embodiment, the support frame member 9 is fixed to the upper surface of a reinforcing frame member 10 made of iron and having an E-shaped cross section by bolts 11 and 11 and nuts 12 and 12. In addition, the gap between the upper surface of the supporting frame member 9 and the lower surface of the intermediate portion of the glass panel 3 is filled and solidified with an adhesive 13, 13 such as structural silicon, and the supporting frame member 9 causes the glass panel to be covered. 3 supports the lower surface of the middle part. 14 is a backup material.

In the case of the glass panel supporting device for a skylight of the present invention configured as described above, since the supporting frame member 9 supports the lower surface of the middle portion of the glass panel 3, the glass panel 3 has a large area and a large thickness. Even if the glass panel 3 having a small size is used, the glass panel 3 is not largely bent, and the glass panel 3 can be prevented from being damaged.

Further, since the supporting frame member 9 and the reinforcing frame member 10 are not exposed on the upper surface of the glass panel 3, the design when the skylight is viewed from above is neat. Further, since the middle portion of the glass panel 3 is adhered to the supporting frame member 9 with the adhesives 13, 13, even when the pressure on the lower surface of the glass panel 3 becomes higher than the pressure on the upper surface, the glass panel 3 is lifted up. Can be reliably prevented.

[0016]

[Effect of device]

 Since the glass panel supporting device for a skylight of the present invention is constructed and operates as described above, even if the area of the glass panel is widened according to the design requirement, the manufacturing cost and weight of the skylight will increase. It can be prevented.
