Description

Technical Field

[0001] The present invention relates to the technical field of metal grid roofing, and more particularly to a high-load-bearing and lightweight metal grid roofing system and an assembly method thereof. Background Art

[0002] A metal grid roof is a large roof structure constructed using metal components such as steel beams, steel columns, and metal sheets, through specific connection methods and structural designs, resulting in a load-bearing and rigid structure. This roofing system is widely used in large public buildings, industrial plants, stadiums, and other venues, and is highly favored for its excellent load-bearing performance, good stability, and low deadweight. The design of a metal grid roof not only focuses on structural stability and safety, but also fully considers aesthetics and cost-effectiveness, making it an indispensable component of modern architecture.

[0003] According to the patent document: CN118407566A, a roof panel unit, and an integrated metal grid roof system and method with this unit are disclosed, and the present invention relates to the field of metal roof technology. By arranging a planting box on the concrete precast panel, a thermal insulation protective layer can be formed on the top of the concrete precast panel, which has a good thermal insulation effect on the house, so that the metal structure installed under the planting box is less affected by the temperature, which can effectively prevent the frequent expansion and contraction of the metal structure, and protect the waterproof performance and structural strength of the metal grid roof system; by planting large-leaf green plants in the planting box, the top of the concrete precast panel can be completely blocked by the large-leaf green plants, effectively avoiding direct sunlight and direct impact of rainwater, playing an effective buffering effect, protecting the surface coating of the metal grid roof system, and extending the service life of the coating and the metal structure; the indoor temperature can be in a relatively stable state, achieving the purpose of improving the comfort of the living environment.

[0004] In the traditional metal grid roof installation process, a large number of truss structures are usually required to provide the necessary support. These trusses not only consume a lot of manpower and time during installation, but also require a large number of screws to fix them. This installation method not only increases the complexity and difficulty of construction, but also significantly increases the overall installation cost. More importantly, during long-term use, due to the influence of various external factors such as temperature changes and vibrations, the screws fixing the roof are prone to loosening. Once the screws are loose, it will directly affect the stability and safety of the roof, and may even cause damage to the roof structure, posing a safety hazard. Summary of the Invention

[0040] When the metal net rack roof main body 21 is installed, first, the bidirectional electric push rod 17 is started, the bidirectional electric push rod 17 works to push the two L-shaped push blocks 18 in the opposite direction, the L-shaped push block 18 moves to drive the hinged block 19 to slide in the inner wall of the sliding groove plate 16, at the same time, the hinged block 19 moves to drive the rotating rod 110 to rotate, the rotating rod 110 rotates to pull the metal net rack roof main body 21 as a whole downwards through the roof truss 22, at the same time that the metal net rack roof main body 21 moves downwards as a whole, the roof rotating rod 24 in the inner wall of the plurality of roof base plate hinged blocks 23 rotates to push the plurality of columnar push-pull rods 142 to move outward, at the same time that the columnar push-pull rod 142 moves, the push block 143 drives the Z-shaped rotating rod 1410 to rotate, the Z-shaped rotating rod 1410 rotates to push the outermost columnar vertical rotating rod 144 to rotate, the columnar vertical rotating rod 144 rotates to drive the L-shaped fixed plate connecting rod 147 to move through the L-shaped fixed plate rotating rod 146, the L-shaped fixed plate connecting rod 147 moves to drive the front and rear two groups of L-shaped fixed plates 149 to move inward, so as to clamp and fix the bottom of the metal net rack roof main body 21, at the same time, when the metal net rack roof main body 21 moves downwards, first, one side of the T-shaped side plate 252 contacts the horizontal rod 15 and is resisted by the horizontal rod 15 to make the T-shaped side plate 252 not continue to fall with the U-shaped vertical plate 251, at this time, the columnar pressing rod connecting block 254 is fixedly connected with the outer wall of the metal net rack roof main body 21, the U-shaped vertical plate 251 no longer moves downwards to make the columnar pressing rod connecting block 254 drive the downward pressing block 256 to slide downwards on the inner side of the T-shaped side plate 252 through the columnar pressing rod 253, the columnar pressing rod 253 moves downwards to compress the spring 255, the spring 255 is buffered when falling through the elastic force, and the downward pressing block 256 moves downwards to drive the side vertical rod 257 to move downwards, the side vertical rod 257 moves downwards to drive the columnar horizontal resisting rod 2513 to slide in the inclined sliding groove 2512 in the inner wall of the sliding groove block 258, so as to make the sliding groove block 258 be pushed by the columnar horizontal resisting rod 2513 to drive the L-shaped reinforcing block 2511 to rotate with the hinged side block 259 and the hinged place of the L-shaped reinforcing block rotating block 2510 as the shaft, so as to make the L-shaped reinforcing block 2511 rotate and be clamped at the bottom of the horizontal rod 15, further enhancing the stability of the metal net rack roof main body 21 after installation. At this time, through the accurate control of the bidirectional electric push rod 17, the metal net rack roof main body 21 can stably and accurately reach the predetermined installation position. After the metal net rack roof main body 21 is completely in place, the bidirectional electric push rod 17 stops working, the L-shaped push block 18, the hinged block 19 and the rotating rod 110 and other components also stop moving, and the whole metal net rack roof main body 21 is stably clamped between the L-shaped fixed plates 149.

[0041] In addition, the application also relates to a high-load light-weight metal net rack roof system and an assembling method, comprising the following steps:

[0042] Step 1: Prepare the required metal grid roof main body 21 and various connecting components, ensure the quality and structural integrity of all components, clean the installation site to ensure that there are no debris that interferes with the installation process, and determine the installation position and height of the metal grid roof main body 21 according to the design requirements;

[0043] Step 2: Connect the bidirectional electric push rod 17 to the fixing frame of the metal grid roof body 21 to ensure that the connection is firm and reliable;

[0044] Step 3: Then, start the bidirectional electric push rod 17, and use its telescopic function to push the L-shaped push block 18 to move in the opposite direction. During this process, pay close attention to the sliding of the hinge block 19 in the slide plate 16 to ensure smooth sliding and smooth rotation of the rotating rod 110, thereby driving the roof truss 22 and the metal grid roof body 21 to descend smoothly as a whole;

[0045] Step 3: While the metal grid roof body 21 is lowering, the rotation of the roof bottom plate hinge block 23 and the roof rotation rod 24 must be observed to ensure that they can work together to push the columnar push-pull rod 142 outward;

[0046] Step 4: The Z-shaped rotating rod 1410 , the columnar vertical rotating rod 144 , the L-shaped fixed plate rotating rod 146 , the L-shaped fixed plate connecting rod 147 and the L-shaped fixed plate 149 are moved and rotated to finally achieve the clamping and fixing of the bottom of the metal grid roof body 21 .

[0047] The working principle of the present application is as follows: when installing the metal net rack roof body 21, first start the bidirectional electric push rod 17. When the bidirectional electric push rod 17 works, the two L-shaped push blocks 18 are pushed in opposite directions. The movement of the L-shaped push blocks 18 drives the hinged blocks 19 to slide in the inner wall of the sliding groove plate 16, and the movement of the hinged blocks 19 makes the rotating rod 110 rotate. The rotation of the rotating rod 110 pulls the metal net rack roof body 21 as a whole to move downward through the roof beam 22. In the process of moving the metal net rack roof body 21 as a whole downward, the roof rotating rods 24 in the inner wall of the plurality of roof base hinged blocks 23 also rotate, thereby pushing the plurality of columnar push-pull rods 142 to move outward. When the columnar push-pull rods 142 move, the push block 143 drives the Z-shaped rotating rod 1410 to rotate, and the rotation of the Z-shaped rotating rod 1410 pushes the outermost columnar vertical rotating rod 144 to rotate. The rotation of the columnar vertical rotating rod 144 drives the L-shaped fixed plate connecting rod 147 to move through the L-shaped fixed plate rotating rod 146, and the movement of the L-shaped fixed plate connecting rod 147 makes the front and rear two groups of L-shaped fixed plates 149 move inward, thereby clamping and fixing the bottom of the metal net rack roof body 21. At the same time, when the metal net rack roof body 21 moves downward, one side of the T-shaped side plate 252 first contacts the horizontal rod 15 and is resisted by the horizontal rod 15, so that the T-shaped side plate 252 and the U-shaped vertical plate 251 stop falling. At this time, the columnar pressing rod connecting block 254 is fixedly connected with the outer wall of the metal net rack roof body 21, and the U-shaped vertical plate 251 no longer moves downward, so that the columnar pressing rod connecting block 254 drives the downward pressing block 256 to slide downward on the inner side of the T-shaped side plate 252 through the columnar pressing rod 253. The columnar pressing rod 253 moves downward to compress the spring 255, and through the elastic force of the spring 255, the buffer during falling is realized. The downward movement of the downward pressing block 256 drives the side vertical rod 257 to move downward, and the movement of the side vertical rod 257 makes the columnar horizontal abutting rod 2513 slide in the inclined sliding groove 2512 in the inner wall of the sliding groove block 258, thereby pushing the sliding groove block 258 to drive the L-shaped reinforcing block 2511 to rotate around the hinged side block 259 and the hinge of the L-shaped reinforcing block rotating block 2510 as the axis, so that the L-shaped reinforcing block 2511 is clamped at the bottom of the horizontal rod 15.
