[0002] Buildings are places humans create as shelter from the natural environment. As environmental awareness grows, society is realizing that the harm man-made structures cause to nature extends beyond energy. The tiles, steel, and glass used in modern buildings are all sources of environmental damage, not only during their production but also during the dismantling of waste. Consequently, the concept of "green building," which aims to "maximize the efficiency of energy resources throughout a building's lifecycle, minimize damage to the natural environment, and provide a livable space for human activity," has gradually emerged. For example, prefabricated roofs are roof structures that are prefabricated in a factory and then transported to the construction site for installation.

[0003] However, in the existing technology, gaps are inevitably generated in the splicing process of prefabricated roof components. These gaps easily become channels for rainwater to penetrate. Even if sealing measures are taken during the construction process, the sealing materials will age and crack over time, resulting in a decrease in waterproof performance. If the aged or damaged sealing measures are not replaced in time, rainwater will continue to penetrate into the roof structure through the splicing gaps, and rainwater can easily penetrate into the interior of the roof through these gaps. Utility Model Content
