Description

Technical Field

[0001] This patent relates to the technical field of concrete curing boxes, and specifically to a concrete curing box that is easy to adjust. Background Art

[0002] After concrete is poured, if the climate is hot and the air is dry, and curing is not carried out in time, the water in the concrete will evaporate too quickly, resulting in dehydration. This will cause the cement particles that have formed a gel to not be fully hydrated and cannot be transformed into stable crystals, lacking sufficient bonding force, and thus flaky or powdery peeling will occur on the concrete surface. At the same time, when the concrete does not have sufficient strength, premature evaporation of water will also cause relatively large shrinkage deformation and dry shrinkage cracks. Therefore, the initial curing work after concrete pouring is very important.

[0003] However, there are still some deficiencies in the existing concrete curing boxes in the prior art. For example, the placement height of the concrete curing box is fixed and cannot be adjusted. When the user needs to take out the concrete test specimens from the inside of the concrete curing box, they need to bend down to pick them up. Therefore, the prior art needs to be improved. Summary of the Utility Model
