Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

The application provides a roof panel.

In the embodiment of the present application, please refer to fig. 1 to 12, two side edges of the roof panel 100 form a connecting locking edge 112, the middle portion of the roof panel 100 is upwardly bent to form a peak 121, the peak 121 is provided with a bearing surface 123/124, and the bearing surface 123/124 protrudes from the top of the connecting locking edge 112. The connecting locking edge 112 of one roof panel 100 is used to connect with the connecting locking edge 112 of another roof panel 100, and the bearing surface 123/124 is used to support the photovoltaic panel 200 so that the connecting locking edge 112 is located below the photovoltaic panel 200.

In the present embodiment, the shape and size of the roof panel 100 can be selected and designed according to actual needs or industry standards, for example, the overall roof panel 100 may be rectangular, and is not limited herein. The material of the roof panel 100 is not limited to a specific material, and may be, but not limited to, a metal plate, and may be formed by a stamping process, a rolling process, or the like. The metal plate is preferably a plate with a corrosion-resistant layer on the surface to improve the corrosion resistance of the plate, such as but not limited to a steel plate. The corrosion-resistant layer is, for example, but not limited to, a paint layer, a zinc-plated layer, etc.

Connecting locking edges 112 are formed on two side edges of the roof panels 100, that is, the connecting locking edges 112 are arranged on two opposite sides of the roof panels 100, and the connecting locking edge 112 of one roof panel 100 is used for being connected with the connecting locking edge 112 of another roof panel 100, so that when the roof panels 100 are installed, the connecting locking edges 112 of two adjacent roof panels 100 are connected with each other, and therefore splicing of a plurality of roof panels 100 can be achieved, an additional connecting structure is not needed, the connecting mode is simple and rapid, and operation is easy. Typically, the connecting locking edges 112 are arranged on both sides of the roof panel 100 in the width direction, i.e. the connecting locking edges 112 extend along the length direction of the roof panel 100, so that the long sides of two adjacent roof panels 100 are connected to each other by the connecting locking edges 112, improving the overall connection stability.

The connecting locking edge 112 may have many structures and shapes, and usually, the connecting locking edge 112 is bent to ensure the two adjacent connecting locking edges 112 are stably connected. The bending directions of the connecting locking edges 112 on both sides of the same roof panel 100 may be the same or different. As shown in fig. 5 to 7, the connecting locking edges 112 on both sides of the same roof panel 100 are bent in the same direction. The connecting locking edges 112 are arranged in a bent shape, in the same roof panel 100, one of the connecting locking edges 112 is a male rib edge, the other connecting locking edge 112 is a female rib edge, and the male rib edge of one roof panel 100 is buckled with the female rib edge of the other adjacent roof panel 100.

When two adjacent roof panels 100 are connected, the male rib of one of the roof panels 100, the connecting sheet of the side sliding support 410, and the female rib of the other roof panel 100 are turned up by a special tool, so that the two adjacent roof panels 100 and the side sliding support 410 are fixedly connected. To facilitate the connection of the roof panels 100 to the side chocks 410, the roof panels 100 are typically provided with raised locations for connecting locking flanges 112 for receiving the side chocks 410. Thus, the wave trough 110 is formed between the connecting locking edge 112 and the wave crest 121, when the photovoltaic panel 200 is installed on the roof panel 100, the bottom surface of the wave trough 110 has a larger gap with the photovoltaic panel 200, so that the wave trough 110 can be used as a heat dissipation channel to improve the heat dissipation capability of the photovoltaic panel 200. Side brackets 410 may be mechanically attached to the roof runners by self-tapping screws.

Wherein, the bearing surface 123/124 protrudes from the top of the locking edge 112, meaning that the height difference between the bearing surface 123/124 and the wave trough 110 is greater than the height difference between the locking edge 112 and the wave trough 110.

For convenience of explanation, the following directions all refer to the orientation of a user on the ground when the roof panel 100 is installed on a roof keel, and the roof panel 100 is installed above the roof keel. It will be appreciated that the middle portion of the roof panel 100 is folded upwardly to form the wave crests 121 and the lower portion of the roof panel 100 is formed with the grooves 150 at locations corresponding to the wave crests 121. The grooves 150 of the roof panel 100 may be adapted to the intermediate fixing supports 420, and the intermediate fixing supports 420 may be mechanically connected to the roof runners by self-tapping screws. Thus, when the photovoltaic roof is assembled to form a photovoltaic roof, the roof panels 100 are carried on the roof keel, the middle fixing support 420 and the side sliding mechanism are connected to the roof keel, the middle fixing support 420 extends into the groove 150 below the wave crest 121 to be clamped, and the connecting sheet of the side sliding support 410 is locked with the side edges of two adjacent roof panels 100. The middle part and the two sides of the roof panel 100 are fixedly connected with the roof keel, so that the stress span is reduced, the stress area is increased, the connection stability of the roof panel 100 and the roof keel is improved, the wind-resistant uncovering capability of the roof panel 100 is improved, the middle part of the roof panel 100 is not prone to deformation, and the problem that the photovoltaic panel 200 is hidden and cracked due to wind uncovering of the roof panel 100 is solved.

It should be noted that the extending direction of the wave peak 121 may or may not coincide with the extending direction of the connecting flange 112. In order to facilitate the fixed connection between the roof panel 100, the photovoltaic panel 200 and the roof runners, optionally, the extending direction of the wave crests 121 coincides with the extending direction of the connecting locking edges 112. The number of the peaks 121 may be one or more, and may be specifically selected and designed according to actual requirements, which is not limited herein. The cross-sectional shape of the peak 121 may be many, for example, it may be rectangular, trapezoidal, dovetail, polygonal, etc., and it is not limited herein, but only needs to make the peak 121 have the bearing surface 123/124. It will be appreciated that the bearing surfaces 123/124 are the upper walls of the peaks 121, i.e. the sides remote from the roof runners. The number of the supporting surfaces 123/124 on each peak 121 may be one, and two adjacent photovoltaic panels 200 are overlapped on the same supporting surface 123/124. Of course, the number of the supporting surfaces 123/124 on each peak 121 can also be two or more, so that two adjacent photovoltaic panels 200 are respectively overlapped on one supporting surface 123/124. The specific design and selection can be made according to the actual use situation, and are not limited herein. The bearing surface 123/124 may be planar or curved. In order to make the contact between the photovoltaic surface and the bearing surface 123/124 of the peak 121 more robust, the bearing surface 123/124 is optionally provided as a flat surface.

It should be noted that, when the connecting locking edge 112 protrudes from the photovoltaic panel 200 and encounters heavy rainfall, the photovoltaic panel 200 guides rainwater to the boss below the connecting locking edge 112, and a bearing platform below the connecting locking edge 112 is prone to water accumulation due to untimely drainage, so that the accumulated water easily overflows the connecting locking edge 112 to permeate into a room from the connecting position of the connecting locking edge 112, thereby causing a water leakage hidden danger. And the bearing surface 123/124 protrudes from the top of the connecting locking edge 112, that is, the height of the bearing surface 123/124 is higher than the top surface of the connecting locking edge 112, so that after a plurality of roof panels 100 form a complete roof by the connecting mode of the connecting locking edge 112, the bearing surfaces 123/124 of the wave crests 121 can provide mounting surfaces for the photovoltaic panels 200, and ensure that the photovoltaic panels 200 can be higher than the left and right connecting locking edges 112 of the roof panels 100, so that the connecting locking edge 112 is located below the photovoltaic panels 200 and is spaced from the photovoltaic panels 200. Therefore, the connecting part of the connecting locking edge 112 of the two adjacent roof panels 100 can be shielded by the photovoltaic panel 200, so that the installation of the photovoltaic panel 200 is satisfied, and meanwhile, the connecting locking edge 112 of the roof panels 100 is prevented from being soaked by rainwater in heavy rainfall, and further, the hidden danger of water leakage is reduced.

This application roof boarding 100 is installed between roofing fossil fragments and photovoltaic board 200, can make the photovoltaic roof have fine fire behavior. And the wave crests 121 are formed by bending the roof panel 100 of the roof panel 100 upwards in the middle, the wave crests 121 having a bearing surface 123/124, the bearing surface 123/124 protruding the connecting locking edges 112 on both sides of the roof panel 100. After a plurality of roof panels 100 are connected by the connecting locking edges 112 to form a complete roof, the photovoltaic panel 200 is installed on the bearing surface 123/124 of the wave crest 121, and it is ensured that the photovoltaic panel 200 can be higher than the left and right connecting locking edges 112 of the roof panels 100, so that the connecting locking edges 112 are located below the photovoltaic panel 200 and spaced apart from the photovoltaic panel 200. So, accessible photovoltaic board 200 shelters from the junction of the connection lockstitch 112 of two adjacent roof boarding 100, avoids the connection lockstitch 112 of roof boarding 100 to suffer the rainwater when raining by force when satisfying the installation of photovoltaic board 200 and soaks, and then reduces the hidden danger of leaking, improves roofing photovoltaic system's leak protection water effect. In addition, the middle part of the roof panel 100 is folded upwards to form the wave crest 121, and the lower part of the roof panel 100 corresponding to the position of the wave crest 121 forms the groove 150 which can be connected with the middle fixing support 420 in a matching way. So, when the equipment formed the photovoltaic roof, the middle part and both sides of roof boarding 100 all with roofing fossil fragments fixed connection, reduced the atress span, increase lifting surface area has promoted roof boarding 100 and roofing fossil fragments's the steadiness of being connected, and then has improved roof boarding 100's anti-wind ability of taking off, and makes roof boarding 100's middle part be difficult for taking place to warp, and then has solved roof boarding 100 and has taken off the hidden problem of splitting of photovoltaic board 200 that leads to because of wind.

In practical terms, as shown in fig. 2, 9, 12, 15 and 16, the roofing photovoltaic system includes at least two roof panels 100, two adjacent roof panels 100 are connected by two adjacent connecting locking edges 112, the two adjacent connecting locking edges 112 cooperate to form a locking structure 111, and the locking structure 111 is located between two adjacent peaks 121 and below the bearing surface 123/124, that is, the bearing surface 123/124 is higher than the highest point of the locking structure 111. In practice, the number and size of roof panels 100 may be selected based on the area of the roof. So that the connecting locking edges 112 of two adjacent roof panels 100 are connected to form the locking structure 111, after a plurality of roof panels 100 are connected to form a complete roof through the locking structure 111, the photovoltaic panel 200 is shielded above the locking structure 111 to prevent water leakage at the locking structure 111.

Referring to fig. 3, 4, and 8 to 17, the peak 121 is bent in multiple sections to have two spaced shoulders 125 and a supporting protrusion 126 protruding from the top of the shoulder 125, the supporting protrusion 126 connects the two shoulders 125, the supporting surface 123 is formed on the top surface of the shoulder 125, the supporting surface 123 is used to support the side of the photovoltaic panel 200, and each supporting surface 123 on two adjacent peaks 121 forms a first mounting position.

In the present embodiment, the bearing surface 123 is a plane. The first mounting location is for mounting the photovoltaic panel 200. Each peak 121 is provided with two bearing surfaces 123, the side edges of two adjacent photovoltaic panels 200 are respectively lapped on one bearing surface 123, so that the two bearing surfaces 123 are distributed on two sides of the peak 121, and the side edges of two adjacent photovoltaic panels 200 can be simultaneously installed on one peak 121. Two sides of each photovoltaic panel 200 are respectively lapped on one bearing surface 123 of two adjacent wave crests 121, so that the two photovoltaic panels 200 can be installed by three wave crests 121, each wave crest 121 can be fully utilized, the number of the wave crests 121 can be reduced, and the photovoltaic panels 200 can be conveniently positioned and installed on the wave crests 121.

Further, as shown in fig. 1 to 19, the peak 121 further includes a supporting protrusion 126 protruding from the top of the shoulder 125, and the supporting protrusion 126 is located between the two bearing surfaces 123, so that each first mounting position is formed between two adjacent supporting protrusions 126. The support protrusion 126 may be protruded from the top surface of the shoulder 125, or may be protruded upward from the top surface of the shoulder 125. Alternatively, the support protrusion 126 is formed by upwardly protruding the top surface of the shoulder 125. So, support the below of protruding 126 and form joint groove 152, can with middle fixing support 420 adaptation joint, further promote the roof boarding 100 and the roof keel between be connected the steadiness. Optionally, the notch of the clamping groove 152 is a reduced opening, the middle fixing support 420 has a clamping portion, and the clamping portion is located in the clamping groove 152 and is matched with the clamping groove 152 to prevent the middle fixing support 420 from being separated. The cross-sectional shape of the support protrusion 126 may be rectangular, hexagonal, circular, oval, etc., and is not particularly limited thereto. Correspondingly, the cross-sectional shape of the intermediate fixing mount 420 is substantially the same as the cross-sectional shape of the support protrusion 126. The same here means the same shape and different size. By positioning the supporting protrusions 126 between the two bearing surfaces 123 and forming each first mounting position between two adjacent supporting protrusions 126, the supporting protrusions 126 can limit and position the side edges of the photovoltaic panel 200, so that the photovoltaic panel 200 is prevented from moving between the two wave crests 121, and the photovoltaic panel 200 can be mounted on the roof panel 100 more conveniently and quickly.

Further, each of the shoulders 125 includes a second sidewall 141 and a second top wall 142, the second sidewall 141 extends up and down and is connected to the wave bottom 110110, and one end of the second top wall 142 is connected to the second sidewall 141 and the other end is connected to the supporting protrusion 126. Optionally, the second side walls 141 of the two shoulders 125 are close to each other from bottom to top, and the two second side walls 141 make the notches of the connecting slots 151 flared, thereby facilitating the insertion of the middle fixing support 420. In some embodiments, the groove 150 has a connecting groove 151 and a clamping groove 152 arranged from bottom to top, wherein the notch of the connecting groove 151 is flared so that the middle fixing support 420 extends into the connecting groove 151.

In an embodiment, referring to fig. 1 to 4, 8, 9, 12, and 15 to 20, the side surface of the supporting protrusion 126 forms a clamping corner 122.

It will be appreciated that the snap corner 122 may be formed by a side portion of the support protrusion 126 protruding outward, i.e., a groove side wall of the snap groove 152 is recessed outward to form the snap corner. The snap corner 122 makes the notch of the snap groove 152 a reduced mouth, for example, making the cross section of the support protrusion 126 hexagonal; the side portions of the support protrusions 126 may also be recessed inwardly to form the snap-in corners 122, for example, to give the support protrusions 126 a cross-sectional shape resembling an hourglass.

In some embodiments, the clamping angle 122 can be realized in a manner that the supporting protrusion 126 has a first top wall 131 and two opposite first side walls 132, each of the first side walls 132 has a first bending section 133 and a second bending section 134 connected thereto, lower ends of the two first bending sections 133 are connected to the two shoulders in a one-to-one correspondence manner, an upper end of the second bending section 134 is connected to the first top wall 131, and the first bending section 133 and the second bending section 134 are arranged at an included angle to form the clamping angle.

Optionally, the distance between the lower ends of the two first bending sections 133 is smaller than the distance between the upper ends thereof; the distance between the lower ends of the two second bending sections 134 is greater than the distance between the upper ends thereof. In this way, a throat is formed between the lower ends of the two first bending sections 133, thereby preventing the middle fixing support 420 from being detached.

Referring to fig. 18 to 20 together, the top surfaces of the peaks 121 form the supporting surface 124. In combination with the above-mentioned embodiment with the supporting protrusion 126, further, referring to fig. 18 to fig. 20, the supporting surfaces 124 are formed on the top surface of the supporting protrusion 126, and two adjacent supporting surfaces 124 together form a second mounting position. The bearing surface 124 is embodied as a plane. The second mounting location is for mounting the photovoltaic panel 200. The supporting surfaces 124 are formed on the top surfaces of the supporting protrusions 126, and two adjacent supporting surfaces 124 together form a second mounting position, so that the photovoltaic panel 200 can be directly placed on the top surfaces of the supporting protrusions 126 of two adjacent wave crests 121, which is more convenient for mounting the photovoltaic panel 200. By forming the shoulder 125 with the bearing surface 123 or forming the supporting protrusion 126 with the bearing surface 124, a user can select to mount the photovoltaic panel 200 on the shoulder 125 or the supporting protrusion 126 according to the use requirement, so as to meet different mounting requirements of the user and improve the use experience of the user.
