High-low-span metal roof expansion joint node structure and construction method thereof
The invention discloses a high-low-span metal roof expansion joint node structure and a construction method thereof. According to the structure, a slidable connecting structure is installed above an expansion joint between a first roof panel and a second roof panel so that expansion adjustment can be effectively conducted on a gap reserved between main structures due to temperature changes, and damage to the expansion joint node structure is avoided; and meanwhile, a second waterproof coiled material, an upper water stop plate, a first waterproof coiled material, a heat preservation plate, a vapor-proof film and a lower water stop plate are sequentially arranged below the expansion joint, the waterproof and anti-seepage effects of the expansion joint can be guaranteed, and the effective heat preservation effect can also be achieved. The high-low-span metal roof expansion joint node structure and the construction method thereof solve the problem that a roof is prone to water leakage due to thermal expansion and cold contraction of a structural material of a waterproof coiled material at the expansion joint position of the metal roof.
本发明公开了一种高低跨金属屋面伸缩缝节点构造及其施工方法，该构造通过在第一屋面板和第二屋面板之间的伸缩缝上方安装可滑移的连接结构，用来有效满足由于温度变化产生的对主体结构之间预留的缝隙做伸缩调节，避免伸缩缝节点构造破坏，同时在伸缩缝下方依次设置第二防水卷材、上止水板、第一防水卷材、保温板、隔汽膜及下止水板，既能保证伸缩缝的防水、防渗漏效果，又能有效的保温效果。本发明解决了金属屋面的伸缩缝位置防水卷材因结构材料热胀冷缩容易导致屋面发生渗漏水的问题。
