Description

[Detailed description of the invention] Industrial application field This invention relates to a mounting device for a daylighting dome installed on the roof of a building.

Conventional technology Daylighting domes, especially plastic daylighting domes, are subject to safety considerations under the Building Standards Act.
It is required that a non-combustible or semi-non-combustible material be placed below the plastic dome plate to form at least a double structure.

However, such a double-structured lighting dome is composed of a plastic dome, a wired glass plate, and a mounting frame material for attaching them to the building frame as its main components. However, with conventional mounting devices, the plastic dome plate holder is placed horizontally outward on the top of the frame made of a shaped material attached to the building frame, and the glass holder is placed inward on the bottom of the same. A structure is adopted in which the plastic dome plates and the wired glass plates are respectively protruded horizontally and supported, and if necessary, they are restrained and fixed from above with screws, etc., in combination with a holding member. For example, Jikko No. 55-44974).

Problems to be solved by the invention However, in the conventional mounting device as described above, both the plastic dome plate and the glass plate below it are fixed to the mounting frame by external screws. Because they were designed to be installed in the building, all of them could be removed from outside, which caused some problems in terms of security.

Therefore, this invention aims to improve security by making the inner wired glass plate in particular impossible to remove from the outside, and when replacing the dome plate or glass plate if it is damaged, it can be replaced in the same way as conventional products. To provide a lighting dome mounting device which enables easy replacement of the mounting frame while keeping the mounting frame attached to the frame.

Means for solving the problem This invention aims to solve the problem by
, an eave part 3 extending outward and diagonally downward from the lower end thereof, a dome receiving part 4 projecting horizontally outward from the upper end of the rising wall 2 , and a lower part of the rising wall 2 or from a position below it. A mounting frame 1 having a glass receiving part 6 extending inward is made of a shaped material such as aluminum, and on the dome receiving part 4 at least one plastic dome plate 10 is attached at its periphery upward through a packing 11. While being fixed with screws 12 from above, a wired glass plate 14 is supported at its peripheral edge on the inner supporting edge 6a of the glass receiving part 6 through packing 13, and has a substantially square-shaped cross section. The glass holding frame 15 has its upper horizontal portion 15a stacked on the glass plate 14 via the packing 11, and the lower mounting portion 15c.
The gist is a lighting dome mounting device in which the glass plate 14 is restrained and fixed by being stacked on the inner base end 6b of the glass receiving part 6 and fixed with screws 16 from below or from the inside. It is something to do.

Function: In the above structure according to this invention, the plastic dome plate 10 is connected to the mounting screws 12 from the outdoor side.
However, the wired glass plate 14 cannot be removed from the same outside. Therefore, illegal intrusion by people from outside can be prevented. On the other hand, the wired glass plate 14 can also be removed from the indoor side by removing the screws 16. That is, although it is impossible to remove it from the indoor side, the wired glass plate 14 can also be removed when necessary while maintaining the attached state of the mounting frame 1. Therefore, in the event that not only the plastic dome plate 10 but also the wired glass plate 14 is damaged or significantly soiled, they can be replaced without any trouble and with a simple operation.

Embodiments Hereinafter, this invention will be further explained based on illustrated embodiments.

The dome mounting device according to this invention has a mounting frame 1
The main components are two plastic dome plates 10 and 20, an outer and an inner one, and a wired glass plate 14.

The mounting frame 1 is made of extruded aluminum, for example, and includes a vertical rising wall 2, an eaves portion 3 extending outward and diagonally downward from the lower end thereof, and an eaves portion 3 extending horizontally outward from the upper end of the rising wall 2. It has a dome receiving part 4, a hanging wall part 5 extending perpendicularly downward from the inner end of the eave part 3, and a glass receiving part 6 extending inward from the upper end thereof. The eave portion 3 has a pair of L facing each other on its lower surface.
An anchor mounting rail 3a consisting of a letter-shaped ridge is provided, and by engaging the rail 3a with the head 7a of the anchor 7 buried in the concrete dome structure A side, the mounting frame 1 can be attached to the structure A side. It is designed to be able to be fixed. In addition, in this fixed state, by hanging the stopper projection 8 provided on the upper part of the outer surface of the hanging wall part 5 on the upper surface of the frame body A, the mounting frame 1 can be held in a predetermined horizontal position. Note that if the frame A side is made of wood, it is also possible to attach the frame 1 by fixing the hanging wall portion 5 with wood screws 9. Note that the hanging wall 5 may be formed continuously at the lower end of the rising wall 2, and the glass receiving portion 6 may be formed so as to protrude inward from the lower part of the rising wall 2 or the upper part of the hanging wall 5. Good as a thing. In the glass receiving part 6 in the embodiment, the outer base end part 6b is inclined obliquely upward, while the inner support edge part 6a is formed upward in a substantially inverted L-shape, and the tip part thereof is formed to have a substantially inverted L-shape. A water receiving groove 17 can be formed therein. Note that 18 is a channel-shaped water receiving portion formed at the lower end of the hanging wall portion 5 so as to protrude inward.

In the attached state of the frame 1 as described above, the two plastic dome plates 10 and 20 have their peripheral edges placed on the dome receiving portion 4 of the frame 1 via the packing 11 as appropriate, and are positioned upwardly, i.e. It is integrally fixed to the dome receiving part 4 from the outside with a mounting screw 12.

On the other hand, the wired glass plate 14 has its peripheral edge placed on the inner supporting edge 6a of the glass receiving part 6 via packing 13 made of synthetic rubber, etc. Fixed. The glass holding frame 15 has a substantially square cross section, and has a vertical part 15b, a horizontal part 15a connected in a T-shape at the upper end, and an inclined mounting part 15c at the lower end. 15a is stacked on the glass plate 14 via the packing 11 as appropriate, and the mounting portion 15c at the lower end is stacked on the outer base end 6b of the glass receiving portion 6, and a set screw is inserted from the inside of the dome, that is, from the indoor side. By fixing the mounting portion 15c to the base end portion 6b of the glass receiving portion 6 with 16, the wired glass plate 14 is restrained and fixed.

In addition, in the figure, in the case of a rectangular dome, 21 is a corner connecting plate 23 that is L-shaped in plan view for connecting the glass holding frames 15, 15 to each other at the corner where adjacent mounting frames 1, 1 intersect. 24 and 25 are dew condensation prevention tapes attached to the exposed inner surface of the mounting frame 1 with an appropriate adhesive.

In the lighting dome mounting structure shown in the above embodiment, in addition to the matters described in the section of the above-mentioned function, the mounting frame 1 is not only attached to the concrete frame A, but also when the frame is made of wood. Even in such cases, it is possible to install it without any problem using nails or wood screws, and in the case of a wooden roof,
After assembling the dome plates 10, 20 and the wired glass plate 14 to the mounting frame 1 in advance, the assembly can be placed on the opening of the roof, fastened with screws, and a sealant applied. In addition, the two plastic dome plates 10, 20 and the wired glass plate 14 can be installed on-site.
The three-layer structure is advantageous in that it can reduce the occurrence of dew condensation.

Effects of the invention As described above, this invention has a structure in which the plastic dome plate can be removed from the outside, that is, from the outdoor side, but the wired glass plate 14 can only be removed from the indoor side. ing. Therefore, it is possible to eliminate the fear of people illegally entering through the roof opening of the daylighting dome, and it is possible to further improve safety from a crime prevention viewpoint compared to the conventional daylighting dome. In addition, even though the wired glass plate 14 can only be removed from the indoor side, the peripheral edge of the glass plate is supported on the inner supporting edge of the glass holder of the mounting frame, The glass holding frame is stacked on top of the outer proximal end of the glass holder and fixed from the inside with screws, so in the unlikely event that the glass plate is damaged, the mounting frame should be replaced. It is convenient to be able to replace the glass plate without having to remove it.
