Frost damage prevention method for cast-in-place concrete beams and slabs
The invention discloses a frost damage prevention method for cast-in-place concrete beams and slabs. Before the concrete beams and slabs are cast, a scaffold is arranged on the ground, and formworks are arranged on the scaffold to cast the concrete beams and slabs. The frost damage prevention method includes the following steps that 1, the periphery of the scaffold is closed; 2, multiple heating devices are erected below the scaffold and used for heating the formwork located on the scaffold; 3, the concrete beams and slabs are cast on the formworks above the heating devices; 4, a sealing film, a straw mattress and an extruded sheet are sequentially laid on the upper surfaces of the concrete beams and slabs to seal cast concrete and preserve the heat of the cast concrete. According to the frost damage prevention method for the cast-in-place concrete beams and slabs, the concrete can be in a positive temperature environment in the casting and curing processes to effectively ensure the early-stage strength of the concrete.
