[0002] At present, stone and metal plates are mainly used for the balcony roofing of the traditional dry-hanging method. Due to the size of the raw materials, most of them are 1.2m segments, resulting in 3-4 seams in a strip-shaped balcony, which greatly increases water leakage. Dangerous; in addition, considering the cost, the material cost of ordinary granite stone is about 200 yuan / square meter, and the material cost of 3mm aluminum veneer sprayed with fluorocarbon is about 350 yuan / square meter, which makes the price of balcony roofing high

The invention relates to a precast concrete coping structure and a manufacturing method thereof. The precast concrete coping structure comprises a precast concrete external wall panel, a cast-in-placeconcrete bearing flanging, precast concrete coping bodies, a galvanized steel sheet water receiving hopper and chemical bolts, wherein the cast-in-place concrete bearing flanging is poured on one side of the prefabricated concrete external wall panel; the precast concrete coping bodies are spliced side by side and are arranged at the tops of the precast concrete external wall panel and the cast-in-place concrete bearing flanging; the galvanized steel sheet water receiving hopper is installed on the top of the prefabricated concrete external wall panel and located below a joint formed by splicing the prefabricated concrete coping bodies; and the chemical bolts are used to connect the cast-in-place concrete bearing flanging and the prefabricated concrete coping body. The prefabricated concrete coping structure and the manufacturing method thereof have the advantages of being low in manufacturing cost, good in waterproof performance, convenient to prefabricate and assemble and the like.
Description
【Technical field】 [0001] The invention relates to a building component and a manufacturing method thereof, in particular to a prefabricated concrete roofing structure and a manufacturing method thereof, and belongs to the technical field of construction engineering. 【Background technique】 [0002] At present, stone and metal plates are mainly used for the balcony roofing of the traditional dry-hanging method. Due to the size of the raw materials, most of them are 1.2m segments, resulting in 3-4 seams in a strip-shaped balcony, which greatly increases water leakage. Dangerous; in addition, considering the cost, the material cost of ordinary granite stone is about 200 yuan / square meter, and the material cost of 3mm aluminum veneer sprayed with fluorocarbon is about 350 yuan / square meter, which makes the price of balcony roofing high. [0003] Therefore, in order to solve the above-mentioned technical problems, it is indeed necessary to provide an innovative prefabricated concr...
