Reinforced concrete slab roof mainly refers to the tiling of precast reinforced concrete hollow slabs or cast-in-situ slabs in order to meet the needs of fire protection or modeling. One is to spread a layer of linoleum on the leveling layer, nail it to the wooden wedges embedded in the board seams, and then nail the tiles to hang the tiles; or directly paint the waterproof cement mortar and attach the tiles on the roof slab. Reinforced concrete slab roofs are often used in antique buildings.
There are several construction methods for the cornice of the vertical wall. The brick cornice is to pick out the bricks one by one at the cornice. Each skin picks out 1/4 bricks, and the total length is no more than 1/2 of the wall thickness. The rafters are directly picked out, suitable for smaller protruding lengths. When the overhang length needs to be large, the overhang wood should be used for overhang, and the overhang wood should be placed under the roof truss. Can also be placed in the load-bearing horizontal wall overhanging wood. When the eaves length is greater, the eaves can be moved down to a certain distance away from the roof truss. At this time, a supporting wood must be added between the eaves and the lower chord of the roof to prevent the overhang of the eaves. The structure of the sloping roof, the sloping roof is a structural layer such as heat preservation and waterproof on the load-bearing structure. Generally, a variety of tile materials, such as flat tiles, corrugated tiles, small blue tiles, metal tiles, and color profiled steel plates, are used as roof waterproof materials. Flat tile roof is a commonly used form at present.
