折板屋盖具有抗震性能好,节省材料、施工工艺较简单等优点,近十多年来,在我国得到了发展。当前影响折板屋盖进一步推广的问题之一是防水问题。工程实践证明,折板屋盖防水效果的好坏,除了设计防水构造作法外,还取决于各道工序的密切配合及折板混凝土浇灌的密实度、平整度。折板的上下缝是折板发生渗、漏的一个重要部位。因此在设计折板屋盖时,要重视折板上、下缝构造的处理。一、折板上、下缝构造处理折板上、下缝在浇灌混凝土时,施工顺序是:首先用钢丝刷将沟缝划毛,然后安装沟缝术模板,浇灌细石混凝土并养护。
The flap roof has the advantages of good anti-seismic performance, material saving, simple construction process, etc. It has been developed in China for more than a decade. One of the issues that currently affect the further promotion of flap roofs is waterproofing. The engineering practice has proved that the waterproof effect of the folded roof is not only the design of the waterproof construction method, but also depends on the close cooperation of various processes and the compactness and flatness of the folding concrete. The upper and lower seams of the flaps are an important part of leakage and leakage of the flaps. Therefore, when designing the folding roof, attention must be paid to the handling of the flaps and the lower seams. First, the folding plate, the lower seam structure treatment Folding plate, the next seam in the pouring of concrete, the construction sequence is: first use the wire brush to ditch the groove joints, and then install the groove joint template, watering fine stone concrete and curing.
