Description

Support frame for solar panels

The invention relates to a support frame for solar panels, in particular to a support frame that can be quickly assembled and fasteners are omitted.

With the rising awareness of environmental protection, green energy has also become an important energy development direction of the country. Using the space on the roof to install solar panels to generate electricity is undoubtedly a feasible model for using space to develop green energy. Since solar panels require a large area of space to be erected, the use of the roof originally used to be exposed to the sun as a field for erecting solar panels can achieve the purpose of making full use of the space. Generally, in the erection process of erecting solar panels, quite a few bolts and nuts are needed to lock the solar support frame with the roof. For example, patent documents such as TW I740774 and TW M619347 all provide related support frame technologies. However, the support frame assembly method using multiple sets of bolts and nuts (fasteners), in addition to the problems of increased cost, complicated structure, and troublesome assembly, because the construction personnel need to spend a long time because of the locking bolts and nuts Waiting for assembly on the roof will lengthen the working hours under the sun and increase the chance of encountering strong winds, which will increase the difficulty and danger of construction.

The main purpose of the present invention is to provide a support frame for solar panels, which can reduce the use of fasteners, save assembly time and increase construction safety.

The bottom ends of the diagonal braces are connected to two opposite ends of the bottom plate and are inclined toward the extension direction of the bottom plate, and can be stretched along a direction of extension of the bottom plate, so that there is a gap between the diagonal braces and the bottom plate. An included angle greater than 90 degrees; one end of the positioning plates is respectively connected to the top of each of the diagonal braces, and there is an included angle greater than 90 degrees between each positioning plate and each of the diagonal braces, and the top of each positioning plate The surface has a first protruding buckle portion, and each of the first protruding buckle portions extends outward in opposite directions along the extending direction of the bottom plate.

From the above, it can be known that when the positioning plates receive a channel steel with their top surfaces, the diagonal braces will be stretched along the extending direction of the bottom plate due to the flexibility of the metal itself, and will be promoted during the stretching process. The first protruding buckle parts are fastened to the corresponding structures (such as grooves) of the channel steel, so as to complete the assembly and positioning of the channel steel without using too many fasteners (such as bolts and nuts). Thereby, the supporting frame of the present invention can achieve the effects of reducing fasteners, reducing costs, saving assembly time and improving construction safety.

Preferably, each positioning plate further has a second protruding buckle adjacent to the first protruding buckle, and the extending direction of the second protruding buckles is perpendicular to the extending direction of the first protruding buckles. Thereby, on the one hand, the positioning plates position the channel steel in the longitudinal direction through the first protruding buckles, and on the other hand, position the channel steel in the width direction through the second protruding buckles.

Preferably, the extension directions of the second protruding buckle parts are opposite to each other, which can further ensure the positioning of the channel steel in the width direction.

Preferably, the base plate has two fixing holes, and the fixing holes have different diameters, so that different types of base plate fixing pieces can be used.

Preferably, the bottom plate further has a base and two legs, and the legs extend obliquely downward from two opposite long sides of the base respectively, so as to increase the strength of the overall structure.

Preferably, each of the braces further has a brace and two first wings, and the first wings are connected to two opposite long sides of each brace to increase the overall structural strength.

Preferably, the positioning plates further have a receiving portion and two second wing portions, and the second wing portions are connected to two opposite long sides of each receiving portion to increase the overall structural strength.

Preferably, there is an included angle greater than 90 degrees between each positioning plate and each of the diagonal braces, so as to limit the angle between each of the diagonal braces.
