我们有大量的老旧平房,每到雨季需要修补,然而,却常出现“不修小漏,修后大漏”的情况。这主要是修补前没有找到“病因”,其次是修补方法不适当。旧式平房一般多为灰瓦屋面,结构又多是木屋架或墙体承重。一般有合瓦、筒瓦、半瓦半灰的棋盘心、仰瓦灰梗、干插瓦、陶瓦及水泥瓦屋面,其次还有青灰顶屋面等。要根据不同屋面寻找漏雨原因及进行修理。 We have a large number of old cottages that need to be repaired every rainy season. However, there are often cases of “not repairing small leaks and repairing major leaks”. This is mainly due to the fact that the “cause” was not found before the repair, and that the repair method was not appropriate. Old-style cottages are generally gray roof tiles, and most of the structures are wooden trusses or wall weights. There are generally tile tiles, tile tiles, half tile half-gray chessboard cores, wavy stalks, dry tile inserts, terracotta tiles and cement tile roofs, followed by green ash ceiling roofs. According to different roofs to find the cause of leakage and repair.
