Abstract
Description
Technical Field
[0001] This utility model relates to the field of roof structure technology, specifically to a one-piece molded large-span metal roof structure. Background Technology
[0002] Metal roofing refers to a roofing system that uses metal sheets as the roofing material, integrating the structural layer and waterproofing layer into one. It is widely used in large public buildings, factories, warehouses, and residences. However, in the construction of extremely long-span metal roofs, using conventional techniques, a 36m span requires at least two joints. Construction at these joints is slow, they are weak points, and there are safety hazards for workers. Furthermore, joints have a higher risk of leakage compared to other locations. Summary of the Invention
[0003] To overcome the shortcomings of existing technologies, this utility model proposes a one-piece molded large-span metal roof structure. The installation is completed in one step, with no seams in a single span, eliminating the risk of water seepage at the joints and providing excellent waterproofing capabilities.
[0004] To achieve the above objectives, the present invention provides a one-piece molded large-span metal roof structure comprising several roof fastener panels, each with a length of 36m or more. The sides of the roof fastener panels are provided with a first locking edge and a second locking edge. Adjacent roof fastener panels are interlocked with each other through the first locking edge and the second locking edge. Several roof fastener panels together form a complete roof. A rainproof structure is provided between the first locking edge and the second locking edge of adjacent roof fastener panels.
[0005] Furthermore, the roofing snap-on panel includes a panel body, a first locking edge and a second locking edge respectively disposed on both sides of the panel body along its length. The first locking edge includes a first folded edge connected to the side of the panel body, a second folded edge connected to the side of the first folded edge away from the panel body, a third folded edge connected to the side of the second folded edge away from the first folded edge, and a fourth folded edge connected to the side of the third folded edge away from the third folded edge. The end of the fourth folded edge is rolled up in the direction away from the panel body.
[0006] Furthermore, the second locking edge includes a fifth folded edge connected to the side of the main body of the board, a sixth folded edge connected to the side of the fifth folded edge away from the main body of the board, a seventh folded edge connected to the side of the sixth folded edge away from the fifth folded edge, an eighth folded edge connected to the side of the seventh folded edge away from the sixth folded edge, and the end of the eighth folded edge is rolled up towards the main body of the board. The eighth folded edge and the fourth folded edge overlap and roll up to achieve locking edge.
[0007] Furthermore, the first and second folds are inclined at the top away from the main body of the board, the third fold is horizontal, and the fourth fold is vertical.
[0008] Furthermore, the fifth and sixth folds are inclined at the top away from the main body of the board, the seventh fold is horizontal, and the eighth fold is vertical.
[0009] Furthermore, the rainproof structure includes a butyl sealing tape at the bottom of the junction of the fourth and eighth folds, and a butyl sealing strip in the middle of the junction of the fourth and eighth folds.
[0010] This utility model's one-piece molded large-span metal roof structure can be cut and installed on-site in one step, with no seams in a single span, eliminating the risk of water seepage at the joints. Furthermore, the rainproof structure between each section is reinforced, further improving the waterproof effect. Attached Figure Description
