The invention discloses a prefabricated plate parapet roof construction method, which comprises the following steps that: (1) a roof prefabricated external wall plate is installed, and a prefabricated superposed beam is arranged at the indoor side of the roof prefabricated external wall plate; (2) a superposed roof plate prefabricated layer is arranged on the top of the prefabricated superposed beam and near the indoor side in a supporting way; (3) a superposed roof plate cast-in-place layer is integrally cast on the top surface of a cast-in-place superposed beam and the top surface of the superposed roof plate prefabricated layer; (4) a parapet prefabricated wall plate is arranged on the top surface of the roof prefabricated external wall plate and the superposed roof plate cast-in-place layer; (5) a glass wool plate is arranged on the superposed roof plate cast-in-place layer; (6) waterproof mortar is smeared on the glass wool plate for leveling; (7) a protection film isolation layer is paved and pasted on the waterproof mortar; (8) a waterproof roll material layer is paved and pasted on the protection film isolation layer; and (9) the mortar layer is sequentially smeared on the waterproof roll material layer, and a reinforcing steel bar compensation shrinkage concrete layer is cast. The method is adopted for reliably connecting the roof prefabricated external wall plate and the parapet prefabricated wall plate.
Description
technical field [0001] The invention relates to the field of assembled monolithic buildings, in particular to a construction method for a prefabricated board parapet roof. Background technique [0002] The application of the prefabricated integral building system not only shortens the construction period, reduces the consumption of on-site materials and equipment, reduces the dust, noise and other hazards caused by traditional building construction to the society, saves labor, fully increases the building usable area, etc. advantages of the people. Using prefabricated panels to install parapet walls and roof panels speeds up the construction progress and improves the roof insulation and waterproof effects. [0003] Authorized patents obtained by searching: [0004] 1 Application number is: Chinese patent CN201010022758.7 discloses "a kind of roof waterproof structure and its manufacturing method". The structure includes the base layer of the roof panel, the insulation lay...
