Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model.

The photovoltaic tile is installed on the roof as the roof of building, not only is used for realizing solar power generation, but also is used for water prevention and drainage of the roof, and the structural design of the photovoltaic tile has important influence on the full utilization of solar energy and the drainage effect of the roof. Therefore, how to fully utilize solar energy and achieve better waterproof and drainage effects is also a problem that needs to be considered in the design of the photovoltaic tile structure.

Referring to fig. 1 and 2, the tile frame 10 in the present embodiment includes a frame 101 for mounting a photovoltaic panel, where one side of the frame 101 is bent upward, so that the tile frame has a bent structure along a lateral direction, based on the requirements of solar energy full use and roof drainage; as shown in fig. 2, the frame 101 has a V-shaped structure on one side of the bend.

In order to facilitate the overlapping installation of the tile frames with the structure on the roof, a first longitudinal overlapping part 102 and a second longitudinal overlapping part 103 are respectively arranged on two sides of the frame body 101 along the longitudinal direction of the tile frames, so that the overlapping installation of the tile frames on the transverse direction of the roof is realized by forming overlapping fit between two adjacent tile frames along the transverse direction through the first longitudinal overlapping part and the second longitudinal overlapping part; at this time, in the state of the lap joint installation, the frame body 101 is inclined with respect to the horizontal plane in the lateral direction.

By combining the structural characteristics of the tile frame, taking the tile frame provided with the photovoltaic module as an example, it can be seen that the photovoltaic module 20 installed on the frame body is obliquely arranged towards one side in the transverse direction of the roof in the installation state, so that the photovoltaic module can better face the direction of solar irradiation, thereby realizing the full utilization of solar energy and improving the efficiency of the photovoltaic tile. Meanwhile, under the installation state of the tile frame, the V-shaped structure at one bending side of the frame body can form a V-shaped drainage groove structure on the tile surface of the tile frame, so that accumulated water can be directly and rapidly drained away from the tile surface, and the tile frame can achieve better drainage effect.

Due to the arrangement of the special bending structure of the tile frame, in the installation state, one side of the tile frame 10 can form an upward arched state, so that the problem of installation stability of the tile frame is caused during installation; in response to this problem, in one embodiment, a support portion 104 is disposed on the back surface of the frame 101 along the lateral direction, and the support portion 104 is configured to provide stable support in the lateral direction for the frame disposed obliquely during tile frame installation, so as to fill the space of the arch formed between the frame and the batten during tile installation. At this time, the arrangement of the supporting part 104 can well solve the problem of the installation stability of the tile frame, and meanwhile, the tile frame can be conveniently installed through the supporting and positioning of the supporting part on the tile hanging strip; and because of the support provided by the support part, the tile frame can bear direct trampling of an installer during installation, and the installation operation of the tile frame on a roof is more convenient, safer and more efficient.

Referring to fig. 5 and 6, in one embodiment, the support 104 is a hollow frame structure, which allows for better structural strength while reducing the overall weight of the tile frame. As can be seen from the figure, the supporting portion 104 is a triangular hollow box structure, and when the lower end face of the supporting portion is positioned and installed on the batten, the tile frame can be in a required installation state and an inclination angle. It will be appreciated that the support 104 may also be of a trapezoidal configuration, or may be formed of a plurality of spaced apart trapezoidal or triangular configurations, all of which are available depending on the functional requirements of the support.

In an embodiment, a tile claw 105 for positioning the support on the batten is provided on the support 104. When the tile frame is installed, the tile frame is positioned in the longitudinal direction by utilizing the horizontal positioning of the lower end surface of the support part on the upper end surface of the tile hanging strip and the matching of the tile claw and the side surface of the tile hanging strip, so that the positioning and the installation of the tile frame are convenient, and the consistency of the installation position of the tile frame is ensured.

Generally, the supporting part 104 is arranged at the position near the upper end of the back of the tile frame, and at the moment, a mounting hole 106 is arranged on the tile frame at the position corresponding to the supporting part for fixedly mounting the tile frame on the tile hanging strip; at the moment, by means of the positioning function of the tile claw on the supporting part, the mounting hole can be exactly corresponding to the position of the tile hanging strip, and the mounting operation of the tile frame is further facilitated.

At this time, based on the arrangement of the structures such as the supporting part, the tile claw, the mounting hole and the like, the stable mounting of the tile frame on the roof can be realized, so that the tile frame has good anti-seismic and windproof effects.

In the design of the mounting hole, as shown in fig. 7, the corresponding position of the mounting hole 106 is set as a boss structure 107, wherein the boss structure 107 adopts a two-stage step structure, the first stage step is set as a trapezoid, the second stage step is set as a cylinder, and the mounting hole 106 is set on the second stage step. Through boss structure's setting, raise the drill way position of mounting hole, avoid ponding to enter into in the mounting hole to prevent to take place to leak in mounting hole position department, and can prevent to form ponding in the mounting hole, lead to the corruption to mounting screw.

In an embodiment, based on the structural characteristics of the tile frame and the arrangement of the supporting portion on the tile frame, when the tile frame is installed, through the installation cooperation between the supporting portion and the batten, a ventilation notch 108 for enabling the lower space of the tile frame to be communicated with the outside is arranged on the supporting portion 104 or on one side of the supporting portion 104. As shown in fig. 5, a ventilation notch is formed on one side of the support part; it will be appreciated that the ventilation notch may also be open to the support portion, also to provide ventilation. In the roof structure formed by the tile frames, the ventilation channels formed by the ventilation gaps can be communicated with the outside, so that hot air formed in the roof lower space can be discharged through the ventilation channels, a good heat dissipation effect on the photovoltaic templates is achieved, and the heat insulation performance of a roof system can be effectively improved.

In an embodiment, as shown in fig. 8 and 9, in the installed state, the overlapping surfaces of the first longitudinal overlapping portion 102 and the second longitudinal overlapping portion 103 are all horizontally arranged, and a clamping fit structure is arranged between the first longitudinal overlapping portion 102 and the second longitudinal overlapping portion 103 for limiting the relative movement between the adjacent overlapping tile frames along the transverse direction. As a specific implementation manner of the snap-fit structure, a lap strap 109 disposed along the longitudinal direction is disposed on the first longitudinal lap portion 102 toward the outside, and correspondingly, a lap slot 110 that mates with the lap strap is disposed on the second longitudinal lap portion 103. Thus, when the lapping surface of the second longitudinal lapping portion is lapped on the lapping surface of the first longitudinal lapping portion, the lapping strip 109 is matched and arranged in the lapping groove 110, so that lapping installation and positioning connection of two adjacent tile frames in the transverse direction are realized.

In the structural design of the second longitudinal lap joint part, the cross section of the second longitudinal lap joint part 103 is set to be a triangular cross section, so that the upper end surface of the second longitudinal lap joint part in the installation state can form a diversion surface inclined to one side, and rainwater can better flow into a V-shaped drainage groove structure formed on the tile surface.

In one embodiment, the first longitudinal lap portion 102 is provided with a longitudinal drainage groove 111 with one end closed and the other end open for drainage of the roof at the lap position; at this time, the lapping strip 109 is disposed in the longitudinal drainage groove 111 along the longitudinal direction, and the height of the lapping strip 109 is smaller than the depth of the longitudinal drainage groove, so that when the accumulated water in the longitudinal drainage groove flows in the outer direction, the lapping strip buffers the water flow, slows down the flow speed of the water flow, and prevents the accumulated water in the drainage groove from overflowing, thereby playing the roles of water prevention and rain leakage prevention.

In an embodiment, as shown in fig. 4, 10 and 11, a first transverse lap portion 112 and a second transverse lap portion 113 are respectively provided at both ends of the frame body 101 in the transverse direction for lap-joint between the tile frames in the longitudinal direction. And a limiting matching structure is arranged between the first transverse lap joint part and the second transverse lap joint part and used for limiting the lap joint position of the tile frame arranged in the adjacent lap joint in the longitudinal direction. As a specific embodiment of a limit fitting structure, a limit step 114 is provided on the first transverse lap joint portion 112 along the longitudinal direction thereof, and a fitting limit protrusion 115 is provided on the second transverse lap joint portion 113 at the end of the frame body.

The second transverse lap joint part 113 of one tile frame is erected on the first transverse lap joint part 112 of the other tile frame, and the lap joint position of the second transverse lap joint part on the first transverse lap joint part is limited by forming a fit between the limit convex strip 115 on the second transverse lap joint part and the limit step 114; therefore, the positioning installation between the tile frames is realized, the consistency of the installation positions of the tile frames is ensured, and the problem that the power generation efficiency of the photovoltaic modules is influenced due to the shielding of the tile frames on the photovoltaic modules installed on the frame body at the transverse lap joint positions can be avoided.

In one embodiment, a lateral drainage groove 116 is formed on the first lateral overlapping portion 112 outside the limit step and is open at one end for drainage operation of the tile frame. When raining, a small amount of rainwater which cannot be timely discharged on the roof enters the transverse drainage groove and is discharged through the transverse drainage groove. The cross section of the bottom of the transverse drainage groove 116 is inclined downwards towards the outer side, and the installation state of the tile frame is combined, so that better drainage and rain leakage prevention effects can be realized.

In this embodiment, as shown in fig. 5, a drainage slope 117 is disposed in the transverse drainage groove 116 at a position corresponding to the bending position of the frame, and one end of the drainage slope 117 extends to the position of the limiting step and is disposed obliquely toward the upper end surface of the limiting step. As a specific implementation structure, the drainage slope surface may be set such that one end of the drainage slope surface extending to the position of the limiting step is flush or nearly flush with the upper end surface of the limiting step. Based on the structural characteristics of the tile frame in the installation state, accumulated water entering the transverse drainage groove can flow to the bending position of the tile frame, and at the moment, the accumulated water at the position can flow into the V-shaped drainage groove structure on the tile surface through the drainage slope surface, so that the accumulated water is directly drained from the tile surface.

In an embodiment, considering the errors of the tile frames in the machining size and assembly, in order to facilitate the installation of the tile frames, the interference between the tile frames during the lapping is avoided, and a yielding gap 118 which can be used for the opening end of the first longitudinal lapping part to extend into is arranged at the opening end of the first transverse lapping part on the frame body 101, so as to ensure the assembly gap between the tile frames during the lapping installation, and ensure that the tile frames have enough adjustment space.

Accordingly, referring to fig. 13, a dovetail joint 119 is disposed at an open end of the first transverse lap joint 112, and a dovetail groove 120 engaged with the dovetail joint is disposed at an open end of the first longitudinal lap joint 102, so that two tile frames disposed along a diagonal direction in a longitudinal direction are engaged with the dovetail groove 120 through the dovetail joint 119 to form a better engaged installation.

In an embodiment, as shown in fig. 3, a mounting groove 121 for mounting a photovoltaic module is provided on the frame 101, and the depth of the mounting groove 121 is set to be smaller than the thickness of the photovoltaic module 20, so that the upper end surface of the photovoltaic module mounted in the mounting groove can protrude from the upper surface of the frame. The advantage of this is that can avoid being located on the terminal surface of photovoltaic module and form the deposition with the hookup location department of framework, and influence photovoltaic module's power generation effect.

In this embodiment, as shown in fig. 3, the frame body 101 is disposed in the mounting groove 121 and is in a hollow structure, so that the weight of the tile frame can be reduced, and the photovoltaic module can better dissipate heat.

Two circles of annular sealing grooves 122 are arranged at the bottom of the mounting groove of the frame body 101, and a communication channel is arranged between the two circles of sealing grooves 122, so that communication is formed between the sealing grooves. When the photovoltaic module is bonded and fixed by the sealant, the sufficient dosage of the sealant can be ensured, so that a good sealing effect is achieved, and sealant overflow caused by too much sealant injection can be avoided.

The tile frame in the above embodiment not only can be used for installing a photovoltaic module and is used as a photovoltaic tile, but also can be used for installing tile modules with different types and materials, such as metal tiles, stone tiles, glass tiles and the like, in the installation groove of the tile frame according to actual use requirements, so as to form roof tiles with different characteristics, thereby meeting the use requirements of different roof systems.

On the other hand, the utility model also provides a roof tile, and the roof tile adopts the tile frame in the embodiment. Referring to fig. 12, taking as an example a roofing tile to which a photovoltaic module is mounted, the roofing tile includes a photovoltaic module 20 and a tile frame 10, and the photovoltaic module 20 is disposed on the photovoltaic tile frame 10 to form a photovoltaic tile.
