Abstract
The invention discloses a bridge concrete precast beam slab steam curing system which comprises a heat supply device, mold plate curing chambers and a controller. The mold plate curing chambers comprise a top plate curing chamber, a side mold curing chamber and a bottom mold curing chamber which are arranged at the periphery of a precast beam slab; a plurality of steam pipes, temperature sensors and humidity sensors are arranged in the top plate curing chamber, the side mold curing chamber and the bottom mold curing chamber, each steam pipe is provided with an electric steam valve and a plurality of steam spraying holes, and the heat supply device is connected with the steam pipes through pipelines; and the controller is electrically connected with the temperature sensors, the humidity sensors and the electric steam valves. The bridge concrete precast beam slab steam curing system is quick to install, simple and convenient to operate and high in automation degree, and greatly improves the working efficiency.
Description
technical field [0001] The invention relates to the technical field of bridge construction, in particular to a steam curing system for bridge concrete prefabricated beams and slabs. Background technique [0002] Bridge concrete prefabricated beams and slabs basically adopt prestressed construction technology, especially some high-grade concrete prefabricated beams and slabs. If they reach the C70 grade, the concrete needs to be cured for 7 days in the normal construction process to meet the release requirements, which greatly prolongs the construction period. In order to save the construction period, shorten the waiting time before stretching, speed up the turnover of prefabricated formwork, and improve the production efficiency of concrete beams and slabs, steam curing is used to heat the concrete prefabricated beams and slabs. On the other hand, it can effectively avoid the crack damage caused by the inconsistent surface temperature of the prefabricated beam and slab. [...
