Description

Technical Field

[0001] The utility model relates to the technical field of concrete test block curing equipment, in particular to a concrete shrinkage curing box. Background Art

[0002] A concrete test block is a cube used to test concrete quality. After mixing, a sample of the concrete is placed in a mold and hardened to form a concrete test block. A concrete curing box is used to store concrete test blocks, providing the ideal temperature and humidity for further hardening, preventing cracks caused by shrinkage during the curing process.

[0003] Common concrete curing chambers feature racks for holding concrete test blocks, and spray or mist devices on the walls to apply water or mist to the concrete blocks for moisture retention. Because water tends to flow downward under gravity, the top of the concrete block is drier than the bottom, making it more susceptible to cracks. Furthermore, due to the varying moisture content, the strength of the top and bottom of the block is uneven, making such test blocks unreliable for concrete quality testing.

[0004] Chinese invention patent publication number CN114227888B discloses a test block curing device for concrete production. The device comprises a curing box, a support plate disposed within the curing box, a placement slot disposed on the top of the support plate, a concrete test mold placed within the placement slot, and engaging slots formed on both sides of the concrete test mold. A rotating shaft is connected to the inner wall of the curing box and is sleeved with a worm gear. The invention discloses that the support plate and placement slot are rotated by the rotating shaft, which simultaneously rotates the test block within the placement slot, allowing the test block to change its vertical orientation. However, when the device is in use, the bottom of the test block is in close contact with the bottom plate of the placement slot, while the top of the test block is exposed to air. Since moisture is more easily absorbed by solids than by air, the bottom of the test block is more moist than the top, making the top of the test block more prone to cracking. Furthermore, the strength of the top and bottom of the test block is uneven, making such a test block unreliable for testing concrete quality. Utility Model Content
