Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel construction method for a daylighting dome.

In recent years, in factories where work is mainly done indoors, domes are being installed on the roofs in order to bring in sunlight and make the work environment brighter, thereby preventing worker fatigue and visual acuity deterioration. However, it has increased.

By the way, to explain a typical conventional daylighting dome by taking a case where it is installed on a folded roof, for example, it uses a molded daylighting material 101 pre-shaped into a predetermined dome shape as shown in Figure 1. In some cases, the lighting material 201 is formed into a predetermined dome shape and attached to the roof at the construction site as shown in FIG.

That is, the daylighting dome shown in FIG. 1 has, as a daylighting material, a wavy, semi-cylindrical short molded daylighting material 101 made of synthetic resin such as acrylic and having horizontal mounting edges 102° 102 on both sides in the width direction.・Using multiple pieces, this lighting material 101...

As a lighting material, a plurality of short and wide concave plate-shaped lighting materials 201 made of FRP etc. with bent edges 202, 202 on both sides in the width direction are used, and the lighting materials 20
1. One bent edge 202 is attached and fixed to the peak part 303 of one folded roof 301 while overlapping and connecting the longitudinal ends of the lighting material 201... The bent edge 202 on the opposite side is bent to form the other folded roof 3.
It is constructed by attaching and fixing it to the 020 mountain top portion 304.

However, since all of these daylighting domes connect short lengths of daylighting material 101 or 201, if sufficient measures are not taken to prevent water leakage at the connection points, rain may leak, especially during heavy rain or downpours. It has the disadvantage of causing
Therefore, it is necessary to connect the lighting material while taking measures to prevent water leakage, such as interposing a suitable leakage prevention material such as a seal, and this connection work is surprisingly troublesome.

This problem arises when constructing a long-length daylighting dome.
This cannot be ignored because the number of connections of lighting materials increases, and it is inevitable that construction efficiency will be considerably reduced.

In theory, to solve this problem, it would be sufficient to use long lighting materials, but in reality, for the following reasons,
At present, no domes using long lighting materials have been constructed yet.

That is, (a) in the case of the molded daylighting material 101 as shown in Fig. 1, it is impossible to obtain a long daylighting material because there is a limit to the size of the mold; (b) Fig. 2 In the case of the concave plate-shaped daylighting material 201, although it is said that a long daylighting material can be obtained by continuous molding, such daylighting material has a bent edge 202 at the side end in the width direction and cannot be rolled. (C) Even if long daylighting materials are used, they must be cut to a size that can be loaded onto a truck bed, etc., since they must be transported to the dome construction site in their concave shape. Even if such long daylighting materials are obtained, the longer they are, the more difficult they are to handle, and with conventional dome construction methods, positioning and installation of the daylighting materials are time-consuming, making it difficult to substantially improve construction efficiency, etc. This seems to be the main reason why long domes with daylighting are actually difficult to construct.

The present invention has been made in view of the above-mentioned current situation, and provides a novel method for efficiently constructing a leak-free lighting dome using a rollable long plate-shaped lighting material. This is what I am trying to do.

Hereinafter, the construction method of the present invention will be explained in detail with reference to the drawings.

3A, 3B and 3C are partial perspective views for explaining the procedure of the construction method of the present invention, FIG. 5
The figure is a partial cross-sectional view of the daylighting dome with a cushion gasket interposed, Figure 6 is a skeletal diagram of the daylighting dome equipped with a long fixture, and Figure 7 A and the opening are the respective positions used in the present invention. FIG. 2 is a sectional view showing an example of a temporary fastener and a lighting fixture in which the temporary fastener is integrally formed.

According to the construction method of the present invention, it begins by arranging and fixing a temporary fixture for positioning the lighting material at one end in the width direction of the location where the elongated lighting dome is to be constructed.

FIG. 3A shows the above-mentioned first procedure when constructing a daylighting dome on a folded roof. Along the line, a plurality of temporary positioning fixtures 4 are arranged at intervals thereon, and one end of a plurality of bridging frames 5 is attached to each temporary fixture 4. Place it on the frame 5...
- Connect one end of the temporary fastener 4 with a bolt nut 6...
- It is collinearly fixed to the peak part 321 of the folded roof 32.

The other end of the frame 5 is directly fixed to the peak portion 311 of the folded roof 31 on the opposite side with bolts and nuts 61.

The temporary positioning fixture 4 used here is a horizontal top plate portion 4 with bolt insertion holes 41, as shown in FIG. 7A.
2, a slanted plate part 43 having an inclination equal to the slope of the folded roof 32, and a folded part 44 at the lower end of the slanted plate part 43, and the temporary fastener 4 of the The plate portion 43 can be stably attached and fixed by abutting against the top and slope portions of the folded roof 32, and the edge 11 of one side in the width direction of the daylighting material 1 can be inserted into the folded portion 44. It has become.

In addition, the bridge frame 5 used here consists of a curved frame main body 51 and acute angle-shaped fittings 52 and 52 integrally welded to opposite ends of the main body 51. A total of three screw holes 511... are drilled near the center and both ends of the mounting tool 52.5.
Bolt insertion holes and screw holes 521 are formed in the horizontal base plate portion and the swash plate portion of No. 2, respectively.

In FIG. 3A, the temporary positioning fixtures 4... and the fittings 52 at one end of the bridge frame 5 are overlapped at the same location, and the bolts and nuts 6... Although they are colinear, it goes without saying that they may be arranged separately and individually attached and fixed to the folded roof 320 and the peak portion 321 with bolts and nuts.

In addition, in place of the positioning temporary stop 4 as described above, a seventh
Lighting fixture 5 with integrally formed temporary fasteners as shown in the figure
3 may be used.

This fixture 53 consists of a horizontal board part 531 with bolt insertion holes 5311 and a swash plate part 53 with screw holes 5321.
The horizontal board portion 5 of the acute angle-shaped fixture body consisting of 2
31 and further provide screw holes 53 on the outside of the swash plate portion 532.
31 are provided in parallel and a temporary fastener is integrally formed, and both swash plate parts 532 and 53 are provided in parallel.
The lighting material 1 can be inserted between the spaces 3 and 3.

Although such a fixture 53 may be arranged separately from the bridge frame 5, it is possible to install it at the same time by simply welding the swash plate portion 532 to one end of the bridge frame 5 and arranging and fixing the frame 5 to the folded roof. It is desirable that the fixture 53 can also be arranged and fixed, as this will save time and effort.

Once the framework of the daylighting dome is completed in this way, the second step is to position the daylighting material.

The opening in Figure 3 shows the procedure for positioning, and here, while unwinding the long daylighting material 1 that has been transported to the construction site in a rolled state, one end edge 1 in the width direction of the daylighting material 1 is are sequentially inserted into the folded portions 44 of the temporary positioning fixtures 4, and held by the folded portions 44 to temporarily fix the lighting material 1. It is positioned so that it is arranged parallel to the peaks and valleys of the roof 32 without being biased.

When positioning in this manner, even one worker can perform quick and accurate positioning very easily.

Of course, this positioning can also be performed after rewinding all of the daylighting material 1, and it is up to the worker's preference whether to position it while rewinding the daylighting material 1 or after rewinding it. All you have to do is decide.

The lighting material 1 used here is sufficient as long as it has good translucency and physical properties that allow it to be rolled in the form of a long plate; ,price,
Overall, from various viewpoints such as ease of handling, a long polycarbonate plate with a thickness of approximately 1 to 5 mm is most desirable.

However, if the polycarbonate plate is slightly curved in the width direction to an extent that does not impair the winding characteristics, it will not wave when unwinding and positioning will be easier.

When the positioning of the daylighting material 1 is completed, the daylighting material 1 is attached as a third step.

Basically, to install this lighting material 1, as shown in Figure 3, first, use screws 7 and washers 8 to tighten the temporarily fastened edge 11 of the lighting material 1. Cross-linked frame 5...

What is necessary is just to attach and fix it to the mountain top part 311.

However, if further strength is required to further improve the mounting strength of the lighting material 1, as shown in FIG. The lighting material 1 is held between the holding frame 50 which has screw holes 501 and has almost the same curvature and length as the frame body 51, and the screws 80...
The bridging frame 5..., the daylighting material 1, and the holding frame 50... may be fixed on the same line.

FIG. 4 is a partial perspective view of a long daylighting dome constructed by the construction procedure described above.

Similarly, this dome is shown with both longitudinal ends removed, giving the impression of a tunnel-shaped dome with an open end, but in reality, synthetic resin end closing members are connected. It is something that

In addition, this lighting dome does not have any vibration-proof cushion packing, but it is of course possible to insert such a packing if necessary.

FIG. 5 shows an example of a dome in which such a cushion packing is interposed. Cushion packings 91, 92 and 93 are interposed between the top portion 311 of the folded roof 31 and the top portion 311 of the folded roof 31, respectively.

In addition, in this daylighting dome, there are no members connecting the bridge frames 5 at the peak parts 311 and 321 of the folded roofs 31 and 32, but this will improve the installation strength and prevent leakage. If necessary, the bridging frame 5 as shown in FIG.
A long fixture 54 with the same cross-sectional shape as the one welded to the bridge frame 5 is inserted between the peaks 31L and 321 between the peaks 31L and 321, and the skeleton with the long fixtures 54 attached and fixed to the peaks 311 and 321 is inserted. If the lighting material 1 is attached and fixed to the long fixture 54, the folded roof 31, 32 and the lighting material 1 will be in close contact with each other over the entire length of the folded roof 31, 32 by the long fixture 54, completely preventing rain leakage. prevention and increase installation strength.

As described above, according to the lighting dome construction method of the present invention,
A temporary fixture for positioning the daylighting material is installed and fixed at one end in the width direction of the dome construction area, and the long plate-like daylighting material that has been selected for the construction site in a rolled state is unwound or rolled. After returning the lighting material, one side edge in the width direction of the lighting material is temporarily fixed with the temporary fastener to position the entire lighting material, making it easy to handle and transport even though it is a long lighting material. Even one worker can quickly and accurately position the lighting material.

Then, in this temporarily fixed state, the temporarily fixed edge of the daylighting material is attached and fixed to one end of the construction area, and then an external force is applied to the opposite edge of the daylighting material to tighten the daylighting material. Since it is curved in the width direction and the opposite edge is attached and fixed to the opposite end of the construction site, it is possible to quickly fix the lighting material board over the entire length without causing any displacement of the lighting material, which is different from conventional methods. The troublesome method of connecting short daylighting materials one by one through leakage prevention material and positioning them while fixing them,
Complexity can be sufficiently eliminated.

The above-mentioned effects are particularly noticeable when a long polycarbonate plate of about 1 to 5 mm, which has good winding properties and bending properties and is easy to handle, is used as the lighting material.

In addition, since the daylighting dome constructed by the method of the present invention has a long daylighting material and no opening, there is no need to worry about rain leakage like in conventional domes, and there is no need for a leakage prevention material. It is possible to save materials and is economically advantageous.
