Electric heating film maintaining trapezoidal beam film

Abstract

The invention relates to an electric heating film maintaining trapezoidal beam film. The electric heating film maintaining trapezoidal beam film comprises a U-shaped rib, a bottom plate, a side plate,a horizontal rib, an electric heating film, a heat-insulating layer and a protective plate, wherein the horizontal rib is arranged on the upper part of the side plate and extends outwards; the bottomplate and the side plate are in rigid connection; the bottom plate and the side plate are shaped like a horn mouth with a big upper part and a small lower part; the electric heating film adheres to the outer surfaces of the bottom plate and the side plate; the heat-insulating layer is arranged on the outer side of the electric heating film; and the protective plate covers the outer side of the heat-insulating layer. After concrete is formed in a mold, the surface of the mold can be directly heated, so that the electric heating film maintaining trapezoidal beam film is simple to operate and high in maintenance speed; furthermore, the horn mouth-shaped template is adopted, a bottom mold and a side mold are connected into a whole, and a precast beam can directly perform lifting and demolding, so that the mold supporting and disassembling process is omitted.

Description

technical field [0001] The invention relates to the technical field of prefabricated component production, in particular to an electrothermal film curing trapezoidal beam mold. Background technique [0002] Inverted trapezoidal beams are large at the top and small at the bottom, so integral molds can be used without support and formwork removal. In order to shorten the time for beams to be molded, steam curing is usually used to accelerate concrete hardening and improve mold turnover efficiency. Transfer, this method puts the casted concrete mold into the steam curing tank, and the water vapor indirectly transfers heat energy to the concrete surface through the closed high temperature environment of the steam curing tank for concrete curing, resulting in serious heat energy loss, low heat energy conversion rate, and The construction process is complicated. There is no report on an electrothermal film curing trapezoidal beam formwork that does not need to support and disasse...
