Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, in particular to a movable prefabricated concrete component steaming and curing device. Background Art

[0002] For concrete projects with large surface coefficients, short curing time requirements, high early strength requirements, or when the natural temperature is low and there are technical difficulties, it is necessary to use a steam curing shed to cure the newly poured concrete. Steam is a good heat carrier. It releases a lot of heat when condensed and has a high heat release coefficient. It can heat and harden the concrete at a higher temperature, and it can also supply a certain amount of moisture to prevent the concrete from drying out and dehydration due to excessive evaporation of moisture.

[0003] At present, workers directly build steam curing sheds around prefabricated components to maintain them. Workers first select a larger open space, then use several brackets to build the skeleton of the curing shed, and then cover the skeleton with a curing hood to form an enclosed space. Then, steam is passed into the curing shed through steam pipes to maintain the prefabricated components. However, building a steam curing shed requires a certain amount of time and physical strength of workers, which is relatively inconvenient. Utility Model Content
