技术领域technical field
本发明涉及现浇混凝土斜屋面的施工方法，尤其涉及大坡度现浇混凝土斜屋面的施工方法。The invention relates to a construction method for cast-in-place concrete sloping roofs, in particular to a construction method for large-slope cast-in-place concrete slant roofs.
背景技术Background technique
坡屋面对建筑造型、保温隔热等有好处，但坡屋面混凝土现浇时，一方面混凝土在重力作用下会沿坡向流动，特别是对大坡坡屋面(坡度≥30°)。另一方面施工人员在坡屋面上施工安全风险加大，不利操作，从而严重影响混凝土成型、密实，最终影响混凝土质量。Sloping roofs are good for architectural modeling, thermal insulation, etc., but when pouring concrete on sloping roofs, on the one hand, the concrete will flow along the slope under the action of gravity, especially for large sloping roofs (slope ≥ 30°). On the other hand, the construction safety risk of construction personnel on the sloping roof increases, which is unfavorable for operation, which seriously affects the formation and compaction of concrete, and ultimately affects the quality of concrete.
一般坡屋面施工方法分为单面模板法、双面夹板支模法，根据实际施工经验，屋面坡度30°以下可采用单面模板法，坡度在30°以上就要采取双面夹板支模法(即封闭法)施工；传统的双面夹板支模施工一般需要在屋面板内设置预埋件用来固定上下模板，施工人员需要站立在大坡度的屋面板钢筋上施工作业，不仅屋现浇屋面板会因为预埋件的埋设有所损坏，而且施工人员操作难度大，影响人员安全和施工质量。Generally, the construction methods of sloping roofs are divided into single-sided formwork method and double-sided splint formwork method. According to actual construction experience, the single-side formwork method can be used for roof slopes below 30°, and the double-side splint formwork method should be used for slopes above 30°. (that is, closed method) construction; traditional double-sided splint formwork construction generally requires embedded parts in the roof panel to fix the upper and lower formwork, and the construction personnel need to stand on the roof panel with a large slope for construction work, not only the cast-in-place roof The roof panel will be damaged due to the embedding of the embedded parts, and it is difficult for construction personnel to operate, which affects personnel safety and construction quality.
鉴于此，如何通过一些技术措施解决大坡度屋面板施工难题，是一个亟需解决的问题。In view of this, how to solve the problem of large-slope roof panel construction through some technical measures is an urgent problem to be solved.
