Description

Technical Field

[0001] The present invention relates to the technical field of roof structures, and in particular to a repair structure and a repair method for an antique roof of an old house. Background Art

[0002] As time goes by, the roof structure of old houses ages and corrodes, and there are problems with roof leakage, so the roof of old houses needs to be repaired. The antique repair of old houses generally involves laying a layer of antique tiles on the top of the old house. The laying of antique tiles includes applying cement on the bottom of the tiles and fixing the tiles to the roof with cement; this construction method is relatively inefficient, and the waterproof property of cement is relatively poor, which affects the waterproof effect of old houses. The laying of antique tiles also involves laying keels on the roof, and then fixing metal or integrated cement tiles to the keels with screws. This construction method is relatively efficient, but when screws are used to connect adjacent tiles, there are gaps between adjacent tiles, which are prone to water seepage, affecting the waterproof effect of the roof.

[0003] Existing patent CN202410101958.3 discloses a construction method for waterproof repair of ancient building roof, including original ancient building roof structure tiles, waterproof coating and lookout bricks, the lookout bricks are installed at the bottom of the ancient building roof structure tiles, the waterproof coating is installed at the top of the ancient building roof structure tiles, and the surface properties of the ancient building roof waterproof tiles are repaired. The waterproof coating is immersed in the ancient building roof structure tiles. The waterproof coating has high elasticity after curing, and has excellent properties such as water resistance, acid resistance, high temperature resistance and corrosion resistance. The construction process is simple, safe and ecological, healthy and environmentally friendly. Although the above patent can improve the waterproof effect of the tiles themselves by soaking the tiles in waterproof coating, the waterproof coating is kept on the tiles for a relatively short time, and the waterproof coating on the surface of the tiles is easily damaged, which affects the waterproof effect of the tiles; in addition, during the tile construction process, the joints of the tiles are prone to water seepage, which affects the waterproof and moisture-proof effects of the house. When the tiles are connected by sticky glue, the stability of the tile connection is relatively poor, which also affects the construction efficiency of tile laying. Summary of the invention
