Construction method for bottom warming of profiled steel plate concrete composite floor
The invention relates to a construction method for bottom warming of a profiled steel plate concrete composite floor. The construction method is characterized in that after a steel I-shaped beam is hoisted, a profiled steel plate is paved on the I-shaped beam; reinforcing bars are tied on the profiled steel plate; a warming plate is closely installed and fixed to the lower surface of the profiled steel plate; concrete is cast on the profiled steel plate; the surface of the concrete is orderly covered with a plastic film, a jute bag and a straw curtain to warm and protect the concrete; and after concrete strength is met, the warming plate is detached. Extra investment is avoided and construction is facilitated; material turnover efficiency is improved and construction quality is guaranteed; a problem is successfully overcome that quick temperature reduction of the concrete surface due to quick heat transmission of profiled steel plate during concrete construction for profiled steel plate concrete combined floor or similar structures in winter; and cost is reduced and great application prospect is achieved.
