Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in the joining structure of a daylighting roof made by combining a plurality of resin daylighting plates in the longitudinal direction.

[Prior Art] Traditionally, factories and other facilities have installed a portion of their steel plate roof, also known as a folded roof, for the purpose of daylighting.
It is being replaced with FRP lighting panels.

Most of these lighting panels are generally semi-cylindrical and made of FRP, and as shown in FIG. 1, they are joined one after another using flanges 2 and 2' formed at both ends. This lighting plate 1 is joined by firmly fastening the opposing flanges 2 and 2' with bolts 5 with the packing 3 and sealing material 4 interposed.
Waterproofing properties will not be compromised in areas with little temperature change.

[Problems to be solved by the invention] However, in such a conventional joint structure, the linear expansion coefficients of FRP and steel plate 7 are significantly different, so in areas where temperature changes are large, the amount of expansion and
The difference in the amount of shrinkage is large and stress concentrates at the joint, especially at the corner R, which may cause cracks 6 and leakage. Furthermore, there is a problem in that joining the lighting panels using bolts is complicated.

The present invention was developed in order to solve the drawbacks and problems associated with the above-mentioned conventional technology, and the purpose is to provide a joint structure for a daylighting roof that does not cause cracks or leaks and is easy to work with. shall be.

[Means for Solving the Problems] The present invention to achieve the above object includes a plurality of approximately semi-cylindrical daylighting plates each made of translucent resin to cover a band-shaped opening formed in the roof. attached to the roof along the longitudinal direction of the opening;
In a joint structure of a daylighting roof in which the longitudinal ends of each daylighting board are overlapped and joined, at the longitudinal end of one of the two mutually adjacent daylighting boards, A bead-shaped bulge protruding toward the outdoors is formed along the width direction of the opening, and the bead-shaped bulge is formed into a base that rises at a steep slope and continues from the main body of the one daylighting plate. a side rising portion; a horizontal portion that is continuous with the side portion and has a curved surface portion that is approximately semicircular in cross section and protrudes toward the outdoors;
A continuous rising part on the front end side extends from the horizontal part toward the end surface of the lighting plate, and the one of the lighting plates is formed at the longitudinal end of the other of the two adjacent lighting plates. A bead-shaped bulge having a shape similar to the bead-shaped bulge formed at the longitudinal end of the lighting plate, and having a gap with respect to the bead-shaped bulge at least to the extent that capillarity does not occur. A bent portion for narrowing the entrance of the gap is formed in the rising portion formed on the tip side of the bead-shaped bulging portion of the other lighting plate, and each of the bead-shaped bulging portions This is a joining structure of a daylighting roof characterized by interposing a seal in the gap. [Function] In the daylighting roof joining structure of the present invention having the above configuration, the daylighting plates are connected to each other with similar shapes formed on each other. By polymerizing and connecting the bead-shaped bulges,
They can be easily connected, making the work easier. Furthermore, the intrusion of rainwater is suppressed by a bent part that narrows the gap communicating with the outdoors, and in addition, the rising part, horizontal part, and curved part reduce the force of rainwater, change its direction, and prevent it from entering. It will be completely blocked.

[Example] Hereinafter, an example of the present invention illustrated in the drawings will be described.

Fig. 2a is a partially sectional side view showing the joint structure of the daylighting roof according to the present invention, and Fig. 2b is a B--B in Fig. 2a.
A sectional view taken along line B, and FIG. 3 is an enlarged sectional view of section C in FIG.

As shown in FIG. 2a, this lighting roof consists of lighting panels 10 adjacent to each other and bead-shaped bulges 11, 11 formed at the ends of each longitudinal direction.
They are elastically joined by fitting a.

The lighting plate 10 is made of a transparent resin such as glass fiber reinforced resin (hereinafter referred to as FRP) using a thermosetting resin such as unsaturated polyester, and is formed into a semi-cylindrical shape as shown in FIG. 2b. As mentioned above, the shape of the lighting board 10 has excellent aesthetics, strength, and
Although a semi-cylindrical shape with excellent lighting and drainage is adopted, the shape is not limited to this, and a shape with a triangular or trapezoidal cross section may also be adopted.

In addition, the lighting board 10, as shown in FIG. 2b,
Both sides of the folded plate roof 12 are fixed to a frame 13 supporting the folded plate roof 12 via waterproof rubber 14 so as to cover a band-shaped opening 17 formed in the folded plate roof 12.
It forms a continuous ridge that is folded back as part of the roof.

As shown in FIG. 3, the bead-shaped bulge 11 protruding toward the outdoors is formed at the longitudinal end of one of the mutually adjacent lighting plates 10. has been done.

The bead-shaped bulging portion 11 includes a base-side rising portion 20 that is continuous with the main body portion 19 located at the center of the one daylighting plate 10 and rises at a steep slope in order to prevent rainwater from blowing up and infiltrating. a horizontal part 22 that has a curved surface part 21 with a substantially semicircular cross section that protrudes toward the outdoors and provides resistance to invading rainwater by changing the flow direction; It is formed from a distal end side rising portion 23 that continues toward the end surface of the plate 10.

Further, at the longitudinal end of the other lighting board 10 among the mutually adjacent lighting boards 10,
Similarly, as shown in FIG. 3, it has a cross-sectional shape corresponding to the cross-sectional shape of the bead-shaped bulging portion 11,
The bead-like swollen portion 11a is formed in such a size that it overlaps the bead-like swollen portion 11 with at least a gap S that does not cause capillary action.

This bead-shaped bulging portion 11a includes a base-side rising portion 20a that rises at a steep incline continuously from the main body portion 19 located at the center of the other lighting plate 10, and a cross-section that continues with this and protrudes toward the outdoors. It is formed of a horizontal portion 22a having a semicircular curved surface portion 21a, and a tip side rising portion 23a that continues from the horizontal portion 22a toward the end surface of the other lighting plate 10. A bent portion 25 is formed at the tip of the tip side rising portion 23a to narrow the entrance 24 of the gap S in order to prevent rainwater and dust from entering the gap S from outdoors.

Therefore, the mutually adjacent lighting plates 10
When connecting the lighting plates 10 to each other, if the bead-shaped bulging part 11 of the one lighting plate 10 and the bead-shaped bulging part 11a of the other lighting plate 10 overlap, the lighting plates 10 can be connected to each other. They can be easily joined without being constrained by each other.

Furthermore, the gap S formed by joining these bead-shaped bulges 11 and 11a is filled with plastic, plastic, or the like to block rainwater that enters through the gap S and prevent it from leaking indoors. A packing 15 made of a water-impermeable elastic material is interposed. This packing 15 is located at the top where the force of the water entering from the gap S is the weakest, that is, the curved surface portion 2 of one of the bead-shaped bulges 11 located on the inside in FIG.
It is glued to the surface of 1 to prevent it from slipping off.

In addition, in the case of this embodiment, this gasket 15 is attached to the curved surface portion 21 of the inner bead-shaped bulge 11, and the third
The other bead-shaped bulge 11 located on the outside in the figure
It may also be attached to the horizontal portions 22, 22a formed on the sides 22 and 22a, respectively. In this case, even when the gap S changes due to expansion or contraction of the daylighting plate 10, the gap S between the horizontal parts 22 and 22a does not change, so the sealing effect is not reduced. In addition, in order to prevent water from entering from the sides of the inner and outer bead-shaped bulges 11 and 11a, a A packing 16 is interposed between the two. Both bead-shaped bulges 11, 11a
The gasket 16 in between may be installed only in the gap S partitioned by the gasket 15 that connects to the indoor space. In this case, the packing 16 does not obstruct drainage from the sides of both bead-shaped bulges 11, 11a.

According to the joint structure of the present invention constructed as described above, infiltration of rainwater is prevented in the following manner. First, even if rainwater is blown up and tries to infiltrate, the tip side rising portion 2 of the bead-shaped bulge portion 11a on the outdoor side
A large amount of rainwater is prevented from entering at the entrance 23 of the gap S narrowed by the bent portion 25 of 3a. Next, the momentum of rainwater blown up at the proximal rising portion 20 and the distal rising portion 23a of both bead-shaped bulging portions 11, 11a is reduced to prevent infiltration. Furthermore, the rainwater that has not been intercepted in both the rising parts 20 and 23a loses momentum due to loss when the flow direction is changed in both the horizontal parts 22 and 22a (loss head in the pipe), and infiltration is blocked. It will be done. Even if rainwater infiltrates further, its momentum is reduced and the direction is changed at the curved surfaces 21, 21a, and the gap S is completely blocked by the packing 15, so no further infiltration occurs and rain leakage occurs. It does not cause

Furthermore, even if the lighting board 10 expands or contracts due to changes in temperature, the joints of the lighting board 10 will
Since the lighting plates 10 are joined so that they are not restrained and can move freely within the gap S between the inner bead-shaped bulge 11 and the outer bead-shaped bulge 11a, stress concentration etc. It will not cause any damage. Moreover, both bead-shaped bulges 11, 11
Since a also serves as a reinforcing rib, the rigidity of the lighting plate 10 is increased.

Furthermore, the assembly work is performed by assembling the lighting panels 1 that are adjacent to each other.
The lighting board 10 is arranged so that the bulges 11 and 11a at both ends in the longitudinal direction overlap each other, and both sides of the lighting board 10 are bolted to the frame 13 of the steel folding plate roof 12.

[Effects of the invention] As described above, according to the invention, a bead-shaped bulge protruding toward the outdoors is provided at the longitudinal end of one of the two adjacent lighting boards. is formed along the width direction of the opening, and the bead-shaped bulging part is connected to a base side rising part that is continuous with the main body part of the one daylighting plate and rises at a steep slope, and a base side rising part that is continuous with this and faces outdoors. The lighting plate is formed by a horizontal portion having a curved surface portion with an approximately semicircular cross section protruding from the horizontal portion, and a rising portion on the tip side that continues from the horizontal portion toward the end surface of the lighting plate, and is formed of two mutually adjacent lighting plates. The other one of the daylighting plates has a shape similar to the bead-shaped bulge formed at the longitudinal end of the one daylighting plate, and has a shape similar to the bead-like bulge formed at the longitudinal end of the one daylighting plate. a bead-shaped bulge having at least a gap that does not cause capillary action, and a rising part formed on the tip side of the bead-shaped bulge of the other lighting plate communicates with the outdoors; By forming a bent part that narrows the entrance of the window and inserting a gasket between the respective bead-shaped bulging parts, it becomes possible to easily connect the lighting panels to each other, and the assembly work is quick and easy. Take things,
Furthermore, the lighting board does not crack or leak due to expansion and contraction. In addition, the intrusion of rainwater
