Construction method of cast-in-place cantilever large-gradient roof
The invention discloses a construction method of a cast-in-place cantilever large-gradient roof. The construction method comprises the steps that A, a cantilever plate with a reinforced concrete structure is formed in a cast-in-place mode; b, a prefabricated plate is manufactured, and preformed holes and U-shaped grooves are reserved in the prefabricated plate; c, the U-shaped grooves and the reserved holes in the prefabricated slabs are in butt joint, and installation pieces are inserted into the U-shaped grooves and the reserved holes which are in butt joint so that the two adjacent prefabricated slabs can be fixed, and the cantilever pitched roof is formed; and D, surface layer concrete is poured on the cantilever pitched roof, and the surface of the cantilever pitched roof is shiny. By means of the construction method, the problems that in the concrete pouring process of the pitched roof, in order to prevent concrete from sliding downwards and accumulating, vibration is insufficient, the compactness of the concrete is not uniform, and the concrete pouring quality is affected can be solved.
本申请公开了一种现浇悬挑大坡度屋面的施工方法。该施工方法，包括：A、现浇形成具有钢筋混凝土结构的悬挑板；B、制成预制板，所述预制板预留预留孔和U型槽；C、将所述预制板上的U型槽、预留孔对接，并使安装件插入已对接的U型槽、预留孔以使相邻二预制板完成固定，以形成悬挑坡屋面；D、在所述悬挑坡屋面上浇筑面层混凝土，并表面收光。本施工方法可解决在坡屋面的混凝土浇筑中，为了防止混凝土向下滑落堆积，振捣不足，混凝土密实度不均匀，影响混凝土浇筑质量等问题。
