Problems solved by technology

Especially when the natural wind blows through the roof, under the influence of negative wind pressure, a large upward pulling force will be generated, which will cause the roof panel to be released, the connection will fail, and the wind will cause damage
The existing metal roof panels have poor wind pressure resistance, especially the joints of the metal roof panels are easily connected and deformed; in addition, the existing metal roof panels have insufficient waterproof performance, and the joints of adjacent metal roof panels are sealed Poor performance, prone to water leakage, water seepage or rainwater backflow; when the temperature changes, the metal roof panel will expand or shrink, crack or deform, and reduce waterproof performance

Embodiment 1

[0032] Such as Figure 1 to Figure 5As shown, the metal roof system of this embodiment includes a roof base plate 40, purlins 50, metal roof panels 100, fixing seats 30, and clip covers 20. The metal roof panels 100 include a base plate 1 and a left Upright rib, right upright rib, described left upright rib comprises the left upright plate 2, left horizontal plate 3, left folded edge 4 that are connected successively, and described right upright rib comprises right vertical plate 5, right horizontal plate 6, right folded edge that are connected successively Side 7, the left horizontal board 3 and the right horizontal board 6 are all in a horizontal state, and between the left vertical board 2 and the bottom board 1 and between the right vertical board 5 and the bottom board 1 are horizontal. An inclination angle, the inclination angle between the left vertical plate 2 and the bottom plate 1 and between the right vertical plate 5 and the bottom plate 1 is α, α=75°~85°, the left...

Embodiment 2

[0034] Such as figure 1 , figure 2 , Figure 6 As shown, the difference between the metal roofing system of this embodiment and Embodiment 1 is that in this embodiment, the fixing seat 30 is in the shape of a strip, and bridges over different purlins 50, and the fixing The seat 30 is combined into an auxiliary support system because the length spans the purlins, which can greatly improve the wind resistance of the roof panel and further enhance the wind pressure resistance of the entire metal roof system. Its span is larger than normal, so it is cost-effective, easy and quick to install, and is suitable for large factories and other buildings.

Abstract

The invention discloses metal roof boards and a metal roof system which have high wind pressure resistant and deformation resistant capacity and excellent waterproof performance. The metal roof systemcomprises the metal roof boards, fixed seats (30) and clamping covers (20). Each metal roof board comprises a bottom plate (1), a left vertical rib and a right vertical rib; each left vertical rib comprises a left vertical plate (2), a left transverse plate (3) and a left folding edge (4), and each right vertical rib comprises a right vertical plate (5), a right transverse plate (6) and a right folding edge (7); the left vertical ribs and the right vertical ribs of the adjacent metal roof boards are connected in a matched mode; the fixed seats (30) are fixedly connected with purlines (50) andmatched with the left vertical ribs and the right vertical ribs in shape; the left vertical ribs are buckled on the fixed seats (30) in an overlapping mode, the right vertical ribs are buckled on theleft vertical ribs in an overlapping mode, and the multiple clamping covers (20) are buckled on the tops of the right vertical ribs and the left vertical ribs; and clamping cover fixing screws (90) penetrate through the clamping covers (20), the right transverse plates (6) and the left transverse plates (3) to fixedly connect the clamping covers (20) with the right vertical ribs and the left vertical ribs into a whole and fixedly connect the metal roof boards (100) with the fixed seats (30) and the purlines (50) into a whole.

Description

technical field [0001] The invention relates to a metal roof panel and a metal roof system comprising the metal roof panel. Background technique [0002] Metal roof panels are the main structural components commonly used in the field of steel structure buildings, and are mainly used in composite roof systems. In the natural environment, wind loads have a huge impact on buildings. Positive wind pressure will be generated on the windward side of the building, negative wind pressure will be generated on the roof and sides, and wind damage will occur if the wind pressure exceeds the value. Especially when the natural wind blows through the roof, under the influence of negative wind pressure, a large upward pulling force will be generated, which will cause the roof panel to break off, the connection to fail, and then cause wind damage. The existing metal roof panels have poor wind pressure resistance, especially the joints of the metal roof panels are easily connected and deform...
