On the other hand, the safety risk of construction personnel on the sloping roof increases, which is unfavorable for operation, which seriously affects the concrete forming and compaction, and ultimately affects the quality of concrete
[0003] 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 will affect the safety of personnel and construction quality

The invention relates to a large-gradient cast-in-place concrete inclined roof construction method. The construction method mainly comprises steps of (1) supporting and building a roof board bed die, (2) installing the roof board bed die, (3) supporting and building a roof board surface die, (4) installing the roof board surface die, (5) installing a construction work bench and (6) casting roof board concrete. The construction method can be simply operated and is advantaged by great component connection rigidity and convenient detachment; and the large-gradient cast-in-place concrete inclined roof construction method possesses great economic and technological benefits.
Description
technical field [0001] 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. Background technique [0002] 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. [0003] 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 roo...
