As an ancient building, for the construction of the roof, we need to have a comprehensive understanding of the traditional construction techniques of roof tiling, and to be familiar with the construction and manufacturing processes of various roof ridges. Two factors must be grasped: one is the problem of waterproofing the roof, and the other is whether the undulations of the roof ridge have reached the design effect and whether it reflects the aesthetic value of the ancient building. These are the two points that should be grasped during the roof construction process.
In the waterproofing treatment of ancient buildings, the use of ash is quite common and very elegant. The use of mud back and grey back is generally called 苫 back, which has the function of waterproof and heat preservation. Generally, a thermal insulation layer is made on the fascia board and the roof is waterproofed. This is the rooftop process after paving the rafters, flying rafters and fascia boards on the wooden frame. Of course, ordinary residential buildings are not covered with rafters, and they are directly covered with rafters. One particular point is to make a double-layer tile, that is, a layer of base tile is laid on the rafter. The bottom tile is generally a tile tile, and then a tube tile is covered on the bottom tile.
The roofs of a large number of antique buildings are cast-in-situ slant roofs, which is completely different from the traditional roof waterproofing. After the waterproof layer is processed, the groove distance should be made on the roof, which is generally set to 22 cm. Too dense is not bright enough. Start to cover the tile. From the bottom to the top, cover the drip tile first. The drip part should protrude from the cornice by 2 cm. When covering the tile, pay attention that the overlap of the upper and lower tiles should be more than 5 cm, usually one-on-two or one-on-three. The gray strips that are laid out at the same time should be even; the ash under the cover tile should be full, and the ash should not overflow too much; the retaining ditch should be upright and the positive ridge should be flat and straight. The installation of all tiles should pay attention to the handling of the joints, and the joints should feel natural, flat and beautiful. After the roof covering is completed, uniform crevices are added to the ditch of each ridge tube, and the ditch is gradually cleaned up, so that no ash can be seen.
For these details, special attention should be paid during construction.
