Description

Technical Field

[0001] The utility model relates to the technical field of building curtain walls, in particular to a heat-insulating metal roof structure. Background Art

[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 positions. If there are too many roll seams in this location and the welding is not reliable, It is easy to tear and lose the waterproof effect. After the roof is built for a long time, leakage occurs in the detailed structure. Firstly, the roof may be relatively high and the slope is large, which affects the difficulty of maintenance and personnel safety. Secondly, the roof area is large, and the water from the leaking point may flow in from another position. This requires that all possible leaking points in the accessories must be repaired at once. In addition, the edges of gutters and other places are easily affected by wind and indoor and outdoor pressure differences during rainy seasons, which easily leads to leakage. In view of the above problems, the inventor proposes an insulating metal roof structure to solve the above problems. Utility Model Content

[0024] By adopting the above technical solution, the insulation component 3 is composed of an insulation layer 31, a support plate 32, a sound-absorbing layer 33 and a waterproof layer 34. The insulation cotton filled between the base plate 2 and the support plate 32 is the insulation layer 31.
