Description

Technical Field

[0002] In the current metal roof structure, the metal roof material is usually made of aluminum-manganese-magnesium alloy, which leads to the location of the detailed structure being the most prone to water leakage. The rolls of corners, roof penetrations, gutter downspouts, overflows and other locations are difficult to fit the base surface and are difficult to weld, making it difficult to ensure waterproof performance. Moreover, the roof will produce repeated fatigue damage to the rolls under the effect of long-term temperature effects. The expansion and contraction caused by the temperature effect will cause stress concentration at the detailed node locations. If there are too many roll seams in this location and the welding is not reliable, it is easy to tear. The waterproof effect is lost. In addition, the edges of gutters and other places are easily leaked due to the wind and the pressure difference between indoors and outdoors during the rainy season. After the roof is built for a long time, leaks occur in the detailed structure. On the one hand, the roof may be relatively high and the slope is large, which affects the difficulty of maintenance and personnel safety. On the other hand, the roof area is large, and the water at the leaking point may flow in from another position. This results in the need to repair all possible leaking points in the accessories at once. In view of the above problems, the inventor proposes a thermal insulation and sound-absorbing TPO waterproof composite board upright lock-edge metal roof structure to solve the above problems.
