[0061] The bottom rectangular frame 230 and the top rectangular frame 220 are both assembled using stainless steel columns. The four corners of the bottom rectangular frame 230 are connected by hemming clips 270. Specifically, the hemming clips 270 include a body 270, an L-shaped slot 272 at the top, and a first connecting slot 273 at the bottom that mates with the first support column 210. During installation, the two stainless steel columns are placed into the L-shaped slots 272 and locked with a locking bolt on one side.

[0062] The connector 250 includes a connector body 251. A U-shaped clip 253 is located at the top of the connector body 251, which has a second connecting slot 252 that mates with the second support column 260.

[0064] The mounting plate 300 primarily serves to form a horizontal mounting platform on either side of the roof frame 100. The mounting plate 300 can be a conventional prefabricated plate. Specifically, the mounting plate 300 described herein is a spliced ​​plate comprising multiple sub-plates. These sub-plates have protrusions on their lower surfaces. The mounting grooves 310 are located within these protrusions. These protrusions engage between two adjacent beams 130. Each sub-plate is prefabricated with reinforced concrete. Furthermore, adjacent sub-plates within the mounting plate 300 are provided with overlapping structures, and sealing gaskets are provided between the overlapping edges.

[0065] The main function of the rain cover 110 is to prevent rainwater from corroding the top beam. Specifically, the rain cover 110 is detachably connected to the top beam 180; the lower surface of the rain cover 110 is provided with a T-shaped sliding groove; the top beam 180 is provided with a mounting block 182 that matches the T-shaped sliding groove; and each end of the mounting block 182 is provided with a limit block 183.

[0067] The main function of the first water receiving box 500 is to collect the water in the installation groove 310 and guide it to drain. Therefore, drainage ports are provided at both ends of the first water receiving box 500.

[0068] The primary function of the second water collection box 600 is to collect rainwater from the lower end of the cover assembly 700, preventing water from leaking between the lower end of the cover assembly 700 and the horizontal mounting platform, which could cause water to drip onto the prefabricated roof. The second water collection box 600 is connected to the first water collection box 500. To save costs and facilitate viewing, both the first and second water collection boxes 500 and 600 are transparent plastic boxes.

[0069] The main function of the cover assembly 700 is to provide shade and protection from rain. The cover assembly 700 can be a common rain shield. In this embodiment, the cover assembly 700 includes a movable frame 710; a slot 720 is provided within the movable frame 710; the upper end of the movable frame 710 is hinged to the top beam 180;

[0070] A plurality of solar cell panels 730 are arranged in the slot 720; a rubber pad is arranged between the solar cell panel 730 and the frame slot 720; a second rubber pad is arranged between two adjacent solar cell panels 730;

[0071] Extension plates 770 are provided around the upper surface of the interactive frame 710 ; a waterproof rubber pad is provided on the lower surface of the extension plate 770 ; and a rotating lock block 760 is provided at the lower end of the movable frame 710 .

[0072] By setting up the solar cell panel 730, solar power generation can be achieved while providing sunshade and rain protection, and green energy can be generated, which is beneficial to energy conservation, emission reduction, and environmental protection.

[0073] During the construction process, first, mark the roof of the prefabricated house. Then, install the mounting bracket 240 at the marked location. The mounting bracket 240 can be fixed to the roof of the prefabricated house using expansion bolts. Then, build the bottom rectangular frame 230. Then, install the first support column 210 and the second support column 260 in sequence. Then, install the top rectangular frame 230 on the first support column 210 and the second support column 260. Finally, install the roof frame 100 on the top rectangular frame 230.

[0074] First, install the third support column 190 on the top rectangular frame 230, install the horizontal beam 160 on the third support column 190, and install the beam 130 on the horizontal beam 160. Install the support beam in the middle of the top rectangular frame 230.

[0075] Next, install the side beam 120 at one end of the horizontal crossbeam 160. First, install the side beam on one side of the horizontal mounting platform. Once the side beams are installed, install the top beam 180 at one end. Top beam 180 can be hoisted and installed using a crane. During the installation of top beam 180, support columns 190 are installed on the supporting crossbeams. The side beam on the other side is then installed on top beam 180. This completes the installation of the entire frame.

[0076] After the frame is installed, the cover panel assembly 700 is installed on the frame, and the first and second water collection boxes 500 and 600 are installed above the top rectangular frame 230. The mounting plate 300 is installed above the crossbeam 130. Finally, the enclosure 800 is installed around the support frame 200. The enclosure 800 can be made of insulation board, and solar panels can be mounted on its outer surface. This allows the entire roof to be overlapped. When roof maintenance is required, one cover panel assembly 700 can be opened and accessed through the mounting hole of the cover panel assembly 700 onto the horizontal mounting platform on the roof to perform maintenance on the entire roof.

[0077] In one feasible embodiment, to enhance overall structural stability, a horizontal crossbeam is positioned in the middle of the top rectangular frame 220; a column 140 is positioned between the horizontal crossbeam and the top beam 180; and each end of the column 140 is detachably connected to the horizontal crossbeam and the top beam 180, respectively, via a clamping member 250. To facilitate adjustment of the installation position during installation, a telescopic column is further positioned between the horizontal crossbeam and the top beam 180. This telescopic column can be constructed by placing a steel pipe at the upper end of a jack, facilitating adjustment during installation.
