Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated box beams, in particular to a prefabricated box beam curing device. Background Art

[0002] Box girder is a type of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box. Box girders are divided into prefabricated box girders and cast-in-place box girders. Prefabricated box girders are an important component of elevated bridges. Box girders usually need to be pre-manufactured in the beam factory. The prefabricated box girders are placed side by side at intervals in the beam factory. This placement is convenient for transportation and maintenance. Prefabricated box girders need to be cured for a long time after casting so that the concrete of the box girder reaches the design strength. During the curing process, the prefabricated box girder needs to be sprayed with water at regular intervals to keep its surface moist.

[0003] The Chinese utility model currently published with the publication number CN218138798U discloses a prefabricated box girder maintenance device, which includes a base, a frame fixedly provided with a front and rear end portion of the base, two winding boxes with a rotating shaft inside, a tarpaulin fixedly provided on the outside of the rotating shaft, and brushes rotatably provided on the outer walls of the two winding boxes located on opposite sides. In the utility model, the tarpaulin on the frame is pulled to the lower end portion of the frame in cold winter, and the double doors are closed, so that the cast box girder is in a closed environment, which is helpful for heat preservation and curing of the prefabricated box girder, and avoids the cold winter environment from freezing the prefabricated box girder. When the box girder does not need to be insulated and cured, the tarpaulin can be rolled up and aired inside the winding box without the need to disassemble and move it, which is beneficial to reducing people's labor and maintenance costs. In addition, the brush contacts the tarpaulin while rolling up the tarpaulin, which is beneficial for cleaning the dust layer accumulated on the surface of the tarpaulin.

Since prefabricated box girders are usually large in size and of different sizes, it is inconvenient for workers to spray water on prefabricated box girders with larger sizes. In addition, in an environment with a high evaporation rate such as summer, it is necessary to spray water on the prefabricated box girders frequently, which increases the work intensity of the workers and reduces the maintenance effect of the prefabricated box girders.
