Description

Support frame for solar panel

This creation is related to a support frame for solar panels, especially a support frame that can be assembled quickly and omits fasteners.

With the rise of environmental protection awareness, green energy has also become an important energy development direction of the country. Using the space on the roof to set up 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 for erection, using the roof originally used to receive sunlight as the field for erecting solar panels can achieve the purpose of making full use of the space. Generally, during the erection of solar panels, a considerable number of bolts and nuts need to be used to lock the solar support frame and the roof together. For example, patent documents such as TW I740774 and TW M619347 all provide technologies for related support frames. However, the assembly method of the support frame using multiple sets of bolts and nuts (fasteners) has the problems of increased cost, complicated structure and troublesome assembly, and it takes a long time for the construction personnel to lock the bolts and nuts. If it is assembled on the roof, the working hours will be prolonged under the sun and the chance of encountering strong winds will increase, which will increase the difficulty and danger of construction.

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

The included angle is greater than 90 degrees; one end of the positioning plates is respectively connected to the top of each of the diagonal braces, there is an included angle greater than 90 degrees between each of the positioning plates and each of the diagonal braces, and the top of each of the positioning plates is The surface has a first protruding buckle portion, and each of the first protruding buckle portions extends along the extending direction of the bottom plate.

It can be seen from the above that when the positioning plates receive a channel steel on their top surfaces, the diagonal braces will be stretched along the extension direction of the bottom plate due to the flexibility of the metal itself, and in the process of stretching The first protruding parts are fastened to the corresponding structures (eg grooves) of the channel steel, so that the assembling and positioning of the channel steel is completed without using too many fasteners (such as bolts and nuts). Therefore, the support frame of the present invention can achieve the effects of reducing fasteners, reducing costs, saving assembly time, and improving construction safety.

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

Preferably, the extending directions of the second protruding 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 they can be used with different types of base plate fixing pieces.

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

Preferably, each of the diagonal braces further has a diagonal bracing portion and two first wing portions, and the first wing portions are connected to two opposite long sides of each diagonal bracing portion 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 of the receiving portions to increase the overall structural strength.

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