Roof Constructions(屋顶结构)研究综述
Roof Constructions 屋顶结构 - Timber roof constructions are commonly ventilated through an air cavity beneath the roof sheathing in order to remove heat and moisture from the construction. [1] Within its wooden roof constructions, rafting wedges were found, which proves that the timber used did not originate in the surroundings of Vienna but had to be transported to the city. [2] Throughfall was excluded by roof constructions in three consecutive growing seasons. [3] The further verification of the effect, produced by the PS, that has no fireproofing, on the time to the limit state of a fireproof steel i-girder requires fire tests and supplementary investigations to evaluate the influence of the PS on the heating of vertical fireproof constructions, including the case of the hydrocarbon fire mode. [4] Double-skin roof constructions have been analysed in the case of pitched roofs or flat roofs without refurbishment in the past; thus, we examined a refurbished structure of a panel building. [5] The uses of timber constructions are very diverse—it is used for the production of exterior wall and roof constructions, window frames and doors, and it is used for dry as well as wet premises. [6]木材屋顶结构通常通过屋顶覆盖层下方的空气腔进行通风，以便从结构中去除热量和水分。 [1] 在其木制屋顶结构中，发现了漂流楔形物，这证明所使用的木材并非来自维也纳周边地区，而是必须运往城市。 [2] 在连续三个生长季节，屋顶结构不包括穿透率。 [3] 由 PS 产生的效果的进一步验证，没有防火，对耐火钢 i 梁的极限状态的时间需要防火测试和补充调查，以评估 PS 对垂直防火加热的影响结构，包括碳氢化合物火灾模式的情况。 [4] 过去曾对未经翻新的斜屋顶或平屋顶的双层屋顶结构进行了分析；因此，我们检查了一个面板建筑的翻新结构。 [5] 木结构的用途非常多样化——它用于生产外墙和屋顶结构、窗框和门，用于干燥和潮湿的场所。 [6]
