The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and are not limiting of the invention. It should be noted that, for convenience of description, only the relevant portions of the related inventions are shown in the drawings.

It should be noted that, in accordance with industry-related standard terminology, reference herein to "electrically connected" may also be referred to as "electrically connected". In addition, without conflict, the embodiments and features of the embodiments of the present invention may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Please refer to fig. 1, which illustrates a partial structural schematic diagram of an embodiment of a lightning protection device for a daylighting roof according to the present invention. As shown in fig. 1, the lightning protection device in the present embodiment may include a plurality of supporting bodies 1, a plurality of stay cords 4, and a wire 6.

It will be appreciated that existing daylighting roofs are typically constructed using multiple panels that are joined together. In order to mount and fix the panel, a plurality of metal keels are generally arranged on the lighting roof. In addition, in order to realize the lighting function of the daylighting roof, the panel of the daylighting roof is usually made of a light-transmitting material, such as a glass panel, a resin panel, and the like.

In this embodiment, the supporting bodies 1 may be respectively disposed at the position of the splice seam of the panel 2 of the daylighting roof. As can be seen from fig. 1, the supports 1 can each be passed through a panel 2 of the daylighting roof. I.e. part of each support 1 may be located inside the panel 2 and part may be located outside the panel 2. The inner side mainly refers to the side of the panel 2 facing the ground (or indoors). In some application scenarios, the inner side may also comprise a splice gap between adjacent panels 2. Whereas the outer side mainly refers to the side of the panel 2 facing away from the ground, i.e. towards the outside. Here, the portions of the supporting bodies 1 located inside the panel 2 may be connected to the metal joists 3 of the daylighting roof, respectively, so that the supporting bodies 1 may be fixed.

In the present embodiment, both ends of each cable 4 may be provided with a cable head 5. In this way, both ends of each cable 4 can be respectively connected with the parts of the two adjacent supporting bodies 1 outside the panel 2 through the cable heads 5. As shown in fig. 1, the stay 4 may be connected to a portion of the supporting body 1 located outside the panel 2 through a head 5. Thereby, the fixing of the cable 4 can be achieved. And each guy cable 4 can extend along the splicing seams of the panel 2 of the daylighting roof respectively, thereby forming a lightning protection lightning receiving grid. That is to say, utilize the cable to replace traditional round steel, form the lightning protection and connect the net of dodging in the outside of daylighting top. And the lightning protection lightning receiving grids formed by the guys can be arranged along the splicing seams of the panel of the daylighting roof. This helps to improve the visual appearance of people inside and outside the building.

In the present embodiment, in order to realize the lightning protection function of the lightning protection device, as shown in fig. 1, each stay 4 may be electrically connected to at least one corresponding support body 1 through a wire 6. It should be noted that each cable 4 is generally connected to two adjacent support bodies 1. In order to simplify the structure and reduce the production cost of the lightning protection device, each stay cable 4 can be electrically connected with one support body 1 connected with the stay cable. Thus, the electrical connection between the stay cable 4 and the support body 1 can be realized, and the reliable electrical connection of the lightning protection device is ensured. Here, in order to further improve the reliability of the electrical connection, each cable 4 may be connected to the support body 1 connected thereto via the lead wire 6.

It can be understood that, under the condition that the relevant requirements such as the supporting strength and the lightning protection grade are satisfied, the material, the structural shape and the size of the supporting body 1, the guy cable 4 and the wire 6, and the connection mode among the components are not limited in the utility model discloses. For example, in order to ensure the firmness of the connection, the support body 1 may be welded to the metal keel 3 of the daylighting roof. For example, the cable head 5 may be detachably connected to the support body 1 to facilitate maintenance and replacement of the cable 4. Here again, the structure of the cable head 5 and the manner of detachable connection are not limited. As an example, the structure of the cable head 5 can be seen in fig. 4. At this time, the cable head 5 may be detachably connected to the portion of the support body 1 located outside the panel by a bolt.

The lightning protection device for the daylighting roof provided by the embodiment can be provided with a plurality of supporting bodies at the position of the panel splicing seam of the daylighting roof. Meanwhile, a plurality of inhaul cables extending along the panel splicing seams of the daylighting roof can be arranged. Therefore, the two ends of each stay cable can be respectively connected with the parts, positioned outside the panel, of the two adjacent supporting bodies through cable heads, so that a lightning protection lightning receiving network is formed. This embodiment provides a new lightning protection device, can expand the lightning protection mode of building. Meanwhile, the lightning protection device can help to improve the appearance visual effect of the daylighting roof (the whole building).

The lighting roof may be formed by splicing panels of various shapes according to various arrangement modes. For example, as shown in fig. 2, triangular panels 2 may be arranged as shown in fig. 2 to form a daylighting roof. It can be seen that the support body 1 (particularly the part located outside the panel) can adopt various structural shapes in order to allow the guy cable 4 to extend along the splicing seam of the panel 2 to adapt to different daylighting roofs. In some embodiments, the cross-sectional shape of the support body 1 may include (but is not limited to) at least one of: cross, T-shaped, L-shaped, Y-shaped, straight, and the like.

In practical engineering, the panels 2 of the daylighting roof are often quadrilateral (e.g., square or rectangular) for ease of manufacture and installation. And typically will be arranged in an array. The panels 2 of the daylighting roof may be arranged in an array of rows and columns, as shown in fig. 3, for example. I.e. the extension directions of the splicing seams between two adjacent rows of panels 2 coincide. And the extension directions of the splicing seams between the two adjacent rows of panels 2 are overlapped.

At this time, each support body can be respectively arranged at the position of the top corner splicing seam of the adjacent panels 2. Therefore, the connecting function of the support body can be fully exerted, and the installation quantity of the support body is reduced. As can be seen in fig. 3, the cross-sectional shape of the support at the edge of the array of panels 2 may include, but is not limited to, a T-shape (e.g., T-shaped support 12) and/or an L-shape (e.g., L-shaped support 11). And the cross-sectional shape of the support located at a non-edge location of the array of panels 2 may comprise a cruciform shape (e.g. a cruciform support 14). At this time, as shown in fig. 4, the support body (cross shape) 1 can be simultaneously connected with four cables. In some application scenarios, the cross-sectional shape of the support at the edge of the array of panels 2 may also include a straight support (such as the straight support 13 shown in fig. 3) according to actual design requirements.

Alternatively, the mounting spacing between adjacent supports may be set according to relevant industry code requirements. Therefore, the lightning protection lightning receiving grid formed by the guy cables meets the relevant size requirements. Furthermore, in order to meet the relevant specification requirements, as shown in fig. 1, the vertical distance between each stay 4 and the panel 2 of the daylighting roof may be not less than 150 mm. And the lead 6 with corresponding size can be selected according to the lightning protection grade of the daylighting roof, so that the cross section area of the lead can meet the requirement.

Further, if there is higher requirement to the amount of deflection of cable in engineering project, then the utility model provides a lightning protection device can also include the connector. As shown in fig. 5, the connecting body 8 may be disposed between adjacent supporting bodies and may pass through the panel 2 of the sunroof. That is, the connecting body 8 is also partly located on the inner side of the panel 2 and partly on the outer side of the panel 2. At this time, the portion of the connector 8 located inside the panel 2 may be connected with the metal keel 3 of the daylighting roof. And the portion of the connecting body 8 located outside the panel 2 can be connected with the corresponding pulling cable 4. The corresponding cable here is generally a cable connected to the adjacent support body where the connecting body is located. In this way, the connecting body 8 may provide additional support to the cable 4. That is, when the span between two adjacent support bodies is large so that the cable connecting the two is long, the connecting body may be disposed at a position where the cable is largely deformed. Therefore, the flexibility of the stay cable can be reduced, and the overall connection firmness of the lightning protection device can be improved.

Here, the connection manner of the connecting body 8, the metal keel 3, and the cable 4 is also not limited. For example, the portions of the connectors 8 located on the inner side of the panel 2 may be welded to the metal studs 3 to improve the security of the connection. For another example, in order to further improve the flexibility of installation and adjustment, a detachable connection may be adopted between the connecting body 8 and the metal keel 3. Like this, can be convenient for adjust the hookup location between connector 8 and the cable 4 to satisfy the in-service use demand. And the part of the connecting body 8 positioned outside the panel 2 can be detachably connected with the inhaul cable 4, so that the inhaul cable can be conveniently dismounted and maintained.

As an example, as shown in fig. 5, the connecting body 8 may be connected to the cable 4 by a clip. In particular, the clip may be nested on the cable 4. Meanwhile, the clamping piece and the connecting body 8 can be provided with fixing holes. Thus, when the connecting body 8 is positioned between the clips and the fixing holes on the two are overlapped, the clips can be clamped and connected with the cable 4 and the connecting body 8 respectively by screwing the bolts penetrating through the fixing holes.

Alternatively, as shown in fig. 1, the wires 6 may also be connected to the corresponding cables 4 and the corresponding support body 1 through the clips 7. I.e. both ends of the wire 6 may likewise be provided with clips 7, respectively. The clamping piece 7 at one end of the wire 6 can be sleeved on the inhaul cable 4. While the clips 7 at the other end can be clamped on both sides of the support body 1. Thereby can realize the clamping connection of clamping piece and cable, supporter through the bolt. Can realize like this that the wire is connected with dismantling of cable, supporter to the dismouting maintenance of the lightning protection device of being convenient for.

It should be noted that, in order to improve the lightning protection effect of the lightning protection device, the above-mentioned wire may be a copper wire, so as to improve the conductivity. In order to prolong the service life of the lightning protection device, the support body 1 may be made of steel. Meanwhile, the stay cable 4 can be made of stainless steel. Compared with the traditional galvanized round steel, the stay cable made of the material has better corrosion resistance. Thereby helping to reduce the occurrence of the situation that the daylighting roof is polluted due to the rusting of the material. In addition, in the practical use process, the inhaul cable in the embodiment can also be used as a connecting structure of the anti-falling device. For example, the worker can fixedly connect the anti-falling safety belt worn by the worker with the inhaul cable. Thereby providing safety guarantee for workers who overhaul, clean and the like.

The utility model also provides a daylighting top. The lighting roof may be provided with a lightning protection device for the lighting roof as described in the embodiments above.

It is understood that the lighting roof in this embodiment may be a lightning protection system separately designed for the lightning protection device. In some embodiments, an embedment may also be provided in the daylighting roof. The positions of the embedded parts can be set according to actual conditions. Therefore, the metal keel of the daylighting roof can be electrically connected with the integral lightning protection system of the building of the daylighting roof through the embedded part. As shown in fig. 6, the embedments 9 may be welded to the reinforcing bars 10 of the lightning protection system of the building as a whole before the concrete is poured. Therefore, the metal keel of the lighting roof is connected with the support body of the lightning protection device. Therefore, the lightning protection device can be connected to the lightning protection system of the whole building, and the construction cost of the lighting roof is favorably reduced.
