Electric heating film cured precast beam integral mould

Abstract

The invention provides an electric heating film cured precast beam integral mould. The electric heating film cured precast beam integral mould comprises a baseplate, side plates, flexible corners, a pull rod, a horizontal beam, electric heating films, heat preservation plates and protecting plates, wherein cavities with upper openings are formed in the baseplate and the side plates; the flexible corners are arranged at the joints of the baseplate and the side plates; the baseplate, the side plates, and the flexible corners are connected to form a whole; the side plates at the two sides are connected through the pull rod at the upper openings; vertical ribs which are spaced by certain distance are welded on the side plates and are perpendicular to the side plates; the vertical ribs are in welded connection with the horizontal beam; baseplate stiffening ribs are welded on the baseplate; the electric heating films are pasted on the surfaces of the baseplate and the side plates; and the heat preservation plates and the protecting plates are arranged on the outer sides of the electric heating films. The electric heating film cured precast beam integral mould greatly improves the work efficiency of the integral beam mold construction, does not need to suffer partitioned supporting and disassembly, has fast mold release speed, good surface forming quality, high heat energy conversionrate, low cost and high curing efficiency, and is cured by using peak electricity; and the turnover speed of the mold is fast.

Description

technical field [0001] The invention relates to the technical field of prefabricated component production, in particular to an integral mold for prefabricated beams maintained by electrothermal film. Background technique [0002] Concrete prefabricated components usually adopt natural curing method for concrete curing, which has the problems of long time consumption and low mold turnover efficiency. The existing technology uses steam curing to accelerate concrete hardening, thereby reducing the curing time and improving mold turnover efficiency. As a heat medium to transfer heat energy, this method puts the casted concrete mold into the steam curing pool, and the water vapor indirectly transfers heat energy to the concrete surface through the closed high temperature environment of the steam curing pool for concrete curing, resulting in serious heat energy loss. The conversion rate of heat energy is low, and the prefabricated beam mold is divided into pieces to support and di...

The existing technology uses steam curing to accelerate concrete hardening, thereby reducing the curing time and improving mold turnover efficiency. As a heat medium to transfer heat energy, this method puts the casted concrete mold into the steam curing pool, and the water vapor indirectly transfers heat energy to the concrete surface through the closed high temperature environment of the steam curing pool for concrete curing, resulting in serious heat energy loss. The thermal energy conversion rate is low, and the prefabricated beam mold is divided into pieces, so the construction efficiency is low

There is no report on a base plate and side plate integrated mold that adopts electrothermal film curing
