Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

As shown in fig. 1, a roof photovoltaic support installation device that side cable supported includes: the roof 1, bracket component and fixed subassembly triplex.

For convenience of description, the roof 1 in this embodiment and fig. 1 is a light steel roof having a V-shaped cross section. However, for those skilled in the art, the roof in the present invention is not limited to a light steel sloping roof, but may be a coiled flat roof, a rigid flat roof, a flat tile sloping roof, a glass fiber reinforced plastic sloping roof, etc., which are not further illustrated herein.

The bracket assembly includes: shaped steel ground beam 2 and photovoltaic sandalwood strip 3. The external profile of the profile steel ground beam 2 is matched with the profile of the roof 1 and arranged on the roof 1, and the photovoltaic sandalwood strips 3 are uniformly fixed on the profile steel ground beam 2 by adopting blind rivets. For the weight and the cost of shaped steel ground beam 2, shaped steel ground beam 2 is by the support frame that a plurality of I shape section bars are constituteed, and install a plurality of triangle-shaped strengthening ribs between the support frame, form a plurality of triangle-shaped space reinforcing structural stability. The fixing assembly includes: supporting reinforcement 4, pulling cable 5 and fixing piece 6. Support reinforcement 4 sets up shaped steel grade beam 2 with 1 side junction of roofing a plurality of cables 5 are installed to shaped steel grade beam 2 both sides, and mounting 6 sets up cable 5 and ground junction. Wherein, through the side of roofing 1 sets up support reinforcement 4 for fixed mounting shaped steel grade beam 2 turns into the decurrent effort of traditional photovoltaic module to roofing 1 to the effort of wall body and to the pulling force on ground, can effectual protection roofing, avoids crushing the roof because photovoltaic module's dead weight.

In a further implementation, as shown in fig. 2, the supporting stiffener 4 comprises: first connecting portion 41, second connecting portion 42, first fixing hole 43, second fixing hole 44. Wherein, first connecting portion 41 fixed mounting is in roofing 1 lateral wall, second connecting portion 42 are for following the dog-ear portion that first connecting portion 41 syncline below extension formed, wherein, the contained angle between first connecting portion 41 and the second connecting portion 42 is 30 ~ 60 degrees. First and

second fixing holes

43 and 44 are provided in the first and

second connection portions

41 and 42, respectively. Through first fixed orifices 43 will first connecting portion 41 fixed mounting will at the lateral wall of roofing 1, will through second fixed orifices 44 second connecting portion 42 are installed the both sides of shaped steel grade beam 2 because the contained angle between first connecting portion 41 and the second connecting portion 42 is 30 ~ 60 degrees, has certain elasticity, and under strong wind effect, support reinforcement 4 can rock by a small margin, offsets partial effort, alleviates shaped steel grade beam 2 to the influence of roofing 1.

In further implementation, as shown in fig. 3, tripods 7 are fixed on both sides of the steel ground beam 2. The tripod 7 comprises: the longitudinal support rods 71 are connected with two ends of the section steel ground beam 2, and the transverse support rods 72 are vertically arranged on the middle points of the longitudinal support rods 71 and connected with the highest point of the section steel ground beam 2. The triangular supports 7 on the two sides are used for supporting, so that the stability of the profile steel ground beam 2 is guaranteed, and the deformation of the profile steel ground beam 2 in the processes of transportation, installation and use is reduced.

In a further implementation, the fixing member 6 is a solid column with an external thread, and is fixed on the concrete ground through a threaded connection. The steel ground beam 2 is resisted by the friction force between the solid pile and the concrete and the friction force between the external thread and the concrete.

In the further implementation process, the outer surfaces of the steel ground beam 2 and the photovoltaic sandalwood strips 3 are coated with anticorrosive paint or coatings. Because the photovoltaic support is generally located outdoors, and is subjected to wind blowing and sunshine for a long time, the external environment has strong corrosivity, and therefore, the outer surface of the photovoltaic support is coated with oil and corrosion resistant paint or coating. In the actual implementation process, the epoxy paint has strong protection capability on the photovoltaic bracket, and the corrosion resistance and durability of the structure can be greatly improved.

In order to facilitate understanding of the technical scheme of the photovoltaic bracket of the foundation-free roof 1, the working principle of the photovoltaic bracket is briefly explained: firstly, because the connecting point of the profile steel ground beam 2 and the roof 1 is positioned on the side surface of the roof 1, the downward acting force of the traditional photovoltaic module on the roof 1 is converted into the acting force on a wall body, the roof can be effectively protected, and the roof is prevented from being crushed due to the dead weight of the photovoltaic module. Because the supporting and reinforcing part 4 is a flexible connecting part, the anti-shaking capability is strong, and the acting force of the photovoltaic module on the wall body is reduced. In addition, the assembly of the profile steel ground beam 2 and the photovoltaic sandal wood strips 3 can be completed in a factory or on the ground, and the requirement of a high-altitude installation construction process on installation strength is reduced.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, the present invention does not separately describe various possible combinations.
