It's all about the roofs of ancient buildings 1. Are the cover tile and the bottom tile stuck together by the cover tile mud? 2. "open it!

As an ancient building, roof construction requires us to have a comprehensive understanding of the traditional construction technology of roof tiles and be familiar with the construction and production technology of various roofs. We should grasp two elements: one is the waterproof problem of the roof, and the other is whether the fluctuation of the roof conforms to the design effect and reflects the aesthetic value of ancient buildings. These are two key points that should be grasped in the process of roof construction.

In the waterproof treatment of ancient buildings, the use of ash is quite common and elegant. The use of mud back and grey back, commonly known as thatched back, has the function of waterproof and thermal insulation. Generally, a thermal insulation pad is made at the top of the surface plate, and the tile roof is waterproof. This is the first working procedure of the roof after the rafters, flying rafters and kanban on the wooden frame are nailed. Of course, ordinary residential buildings do not do back construction, but directly cover the rafters with tiles. One thing to note is that to make a double-layer tile is to spread a layer of bottom tile on the rafters, usually tiles, and then cover a layer of pipe tile on the bottom tile.

At present, the roofs of a large number of antique buildings are cast-in-place concrete sloping roofs, which are completely different from the traditional roof waterproofing. After the waterproof layer is treated, the ditch spacing on the roof should be well done, which is generally set at 22 cm, which is too dense and not bright enough. Start to cover ceramic tiles, from bottom to top, first cover the drip tile, and the drip tile part should extend out of the cornice by 2 cm. When paving tiles, pay attention to the fact that the upper and lower tiles are above 5 cm, usually two or three pieces in one shop. When paving tiles, the paved gray bars should be uniform; When covering the pipe tile, the ash below should be enriched, so as not to overflow too much ash; Trenches should be set vertically and ridges should be straight. All ceramic tile installation should pay attention to the treatment of joints, and feel the joints are natural, smooth and beautiful. After the roof tile cover is completed, the gaps between each ridge and the pipe tile trench are evenly jointed, and the tile trench is gradually cleaned to achieve the purpose of using ash instead of ash.
