The invention discloses a concrete prefabricated slab revetment cast-in-place capping plate formwork structure and a construction method. The method comprises the steps that a revetment side steel formwork, a ground side steel formwork and an end formwork are prefabricated; the revetment side steel formwork is erected on a concrete prefabricated slab revetment, inclined supports are erected on therevetment side steel formwork, the revetment side steel formwork is connected with the inclined supports through adjustable supporting rods, and the perpendicularity of the revetment side steel formwork is adjusted through the adjustable supporting rods; the ground side steel formwork is erected on backfill soil, the ground side steel formwork is fixed to the backfill soil through a triangular fixing support, and the end formwork is fixedly connected with the ground side steel formwork and the revetment side steel formwork; concrete is poured into an area defined by the revetment side steel formwork, the end formwork and the ground side steel formwork; and after concrete pouring and vibrating of a capping plate are completed, a movable scraping frame is adopted for trowelling and flattening cast-in-place concrete. The turnover rate of formwork components is increased to a certain degree by adopting prefabricated components, and the construction cost is reduced.
Description
technical field [0001] The invention relates to the field of civil engineering, in particular to a concrete prefabricated slab slope protection cast-in-place roofing slab formwork structure and a construction method. Background technique [0002] The capping slab is the umbrella on the slope protection of the concrete prefabricated slab, and is the "lip" of the slope slab. "The lips are dead and the teeth are cold", and the damage to the slope protection caused by the damage of the capping plate is very common. Common capping slabs include floating roof and flat roof. Floating roof capping slabs are mainly unsightly, prone to extrusion displacement, and have little protection for side slope slabs, so they are rarely used now. The flat-top capping plate is more beautiful, and it is not easy to be squeezed and displaced. The single-sided vertical formwork cast-in-place method is adopted for the construction of the flat top capping slab. In this way, the flat top capping slab...
