Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a lighting window (skylight) on a roof.
The present invention relates to a method used for constructing an interior duct for a lighting window which is attached so as to extend from a roof to a ceiling when it is provided.

[0002]

2. Description of the Related Art Conventionally, when this kind of duct is constructed,
Measure the dimensions of each part of the construction site at the site, cut around the panels that make up the four circumferential walls of the duct according to these dimensions, assemble the panels cut to the predetermined dimensions to form the duct, And between the ceiling.

[0003]

However, in such a conventional example, it is necessary to actually measure the dimensions of each part on site, and it is necessary to cut out a complicated shape by inking in accordance with the actually measured dimensions. There is a problem that it takes a long working time. The present invention has been made in view of the above-described problems, and the object of the present invention does not require dimensional measurement on site, and the cutting may be a simple straight cut in which the lower portion is aligned with the horizontal plane of the ceiling. An object of the present invention is to provide a method for constructing an interior duct for a lighting window which can shorten a working time.

[0004]

To achieve the above object, the present invention provides a method for constructing an interior duct for a daylighting window, comprising the steps of: forming a rectangular side panel 1 having an upper edge inclined along a roof slope and a lower edge horizontal. Is disposed below the lighting window opening 3 of the roof 2 and the upper end of the side panel 1 is temporarily fixed to the frame 4 of the lighting window opening 3, and the ceiling panel is fixed to the side panel 1 in this temporarily fixed state.
Along the side panel, then remove the temporary fixing of the side panel 1
Then, with the side panel 1 lowered, follow the marking line
To cut the lower part of the side panel 1, cut the lower part of the rectangular ridge side panel 5 and the eave side panel 6 in accordance with the side panel 1, and then connect the side ends of the pair of side panels 1 to the ridge side panel 5 and the eave side. A rectangular tubular duct A is assembled by joining to the side end of the side panel 6, and then the upper end of the side panel 1 and the upper ends of the ridge side panel 5 and the eaves side panel 6 are permanently fixed to the frame 4. I do.

[0005]

According to the above construction, the upper end of the side panel 1 is temporarily fixed to the frame 4 and the ceiling panel is fixed to the side panel 1 in this temporarily fixed state.
Ink along the bell, then temporarily fix the side panel 1
With the side panel 1 down and along the marking line
By cutting the lower portion of the side panel 1 and cutting the lower portions of the ridge side panel 5 and the eaves side panel 6 in accordance with the side panel 1, it is possible to cut the place to be constructed without actually measuring the dimensions of the place to be constructed. The size can be easily adjusted, and the cutting can be easily performed only by cutting straight and horizontally.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A side panel 1 is formed in a rectangular shape in which an upper edge is an inclined edge along a predetermined roof gradient and a lower edge is horizontal. The upper edge of the side panel 1 and the ridge side edge of the side panel 1 are at right angles, and the lower edge of the side panel 1 and the eave side edge of the side panel 1 are at right angles. The ridge-side panel 5 and the eave-side panel 6 have a rectangular shape, and an upper reinforcement 7 and both side reinforcements 8 are attached to the back of the ridge-side panel 5 and the eave-side panel 6. The roof 2 is provided with a rectangular lighting window opening 3, and a lighting window peripheral wall 10 is erected on the lighting window opening 3.
A lighting window door 11 is attached to the upper end of the camera. Lighting window opening 3
A rectangular frame 4 is mounted on the roof side around the. A ceiling edge 13 for attaching a ceiling plate 12 is attached to the ceiling.

[0007] When the interior duct for the lighting window is constructed between the roof 2 and the ceiling, the following is performed. First, as shown in FIG.
And the upper end of the side panel 1 is temporarily
Then, a water thread 15 is stretched along the lower surface of the ceiling edge 13 to raise the ceiling level, and ink is drawn out along the ceiling level. Then, the temporary fixation of the side panel 1 is removed, and the side panel 1 is cut down along the marking line in a state of being lowered (the cross-hatched portion is a portion to be cut and removed). The side panel 1 may be temporarily fixed to both or one of the pair of side panels 1 (in one case, the other side panel 1 is cut in accordance with the cut and cut side panel 1). ). Next, the lower portions of the ridge-side panel 5 and the eave-side panel 6 are cut in accordance with the side panel 1 as shown in FIG. 3 (cross-hatched portions are portions to be cut and removed), and the ridge-side panel 5 and the eave-side panel 6 are cut off. The lower reinforcing member 16 is attached to the lower part of. Next, a pair of side panels 1 and a ridge side panel 5
The eaves-side panel 6 is arranged in a predetermined state, and the joining nail 17 is driven into the side ends of the ridge-side panel 5 and the eaves-side panel 6 from the side end of the side panel 1 to assemble the duct A. Next, as shown in FIG. 4, the receiving hardware 18 is attached to the frame 4, the entire duct A is lifted, and the upper ends of the side panel 1 and the ridge side panel 5 are permanently fixed to the frame 4 with the permanent fixing nails 24. At this time, the eaves side panel 6 is attached via the receiving hardware 18 and the duct A
Is attached to the frame 4 via a packing 19. The duct bezel 20 is attached to the lower four sides of the duct A thus attached with the fixing nail 23. A duct edge 20 is attached to a lower end of the ridge side panel 6 via a fixing hardware 21. Next, the ceiling panel 12 is attached using the ceiling edge 13 and the duct edge 20, and the frame is fitted to the lower end of the duct A and attached.

FIGS. 1 (a) and 1 (b) show an interior duct for a lighting window constructed as described above. FIG. 1A shows a case where the inclination of the upper edge of the side panel 1 is the same as that of the roof, and FIG. 1C shows a case where the inclination of the roof is lower than the inclination of the upper edge of the side panel 1. In any case, the two angles θ ₁ and θ _{2 on the} daylighting window side are constant, and θ ₁ is a right angle. In the case shown in FIG. 1A, the angle of θ ₃ on the ceiling side is a right angle because the roof slope and the angle of the upper edge of the side panel 1 are the same. Angle when theta ₃ the angle of the upper edge of the roof slope and the side panel 1 changes varies.

According to the present invention temporarily stops the upper end of the side panel to the frame of the light-receiving window opening as narrative, the side in the temporarily fixed state
Ink on the front panel along the ceiling level and then on the side panel
Remove the temporary fixing of the flannel, and with the side panel down
Cut the lower part of the side panel along the marking line, cut the lower part of the rectangular ridge side panel and the eaves side panel according to the side panel, and then cut the side edges of the pair of side panels to the ridge side panel and the eaves side. Assemble the rectangular tubular duct by connecting to the side edge of the panel, and then permanently fix the upper edge of the side panel, the upper edge of the ridge side panel and the upper edge of the eaves panel to the above frame, so do not actually measure the dimensions of the installation place Can be easily adjusted to the dimensions of the place where it is to be installed, and can be easily cut only by cutting it horizontally horizontally, greatly reducing on-site labor compared to conventional methods. It is possible to shorten the working time.
