Description

Background

In the construction field, concrete prefabricated parts are increasingly used. The quality and performance of the concrete prefabricated member are greatly dependent on the key link of maintenance. Curing of the concrete pre-form means that the concrete pre-form is hardened and reaches the design strength under certain conditions by specific equipment and methods at certain temperature, humidity and time.

The existing precast concrete curing device generally comprises a curing chamber, wherein a plurality of vertical limiting grooves are formed in the inner side wall of the curing chamber, precast products are inserted into the limiting grooves, a spraying unit is arranged at the top of the curing chamber, and the spraying unit is used for spraying water to the precast products for curing. In the process of curing the prefabricated member, the water sprayed by the spraying unit falls to the top of the prefabricated member, then slowly flows to the bottom along the side surface, and the water is cured in the flowing process.

However, the drawbacks of this solution are: in the flowing process of the water, the water absorbs hydration heat released by the hydration reaction of the concrete, so that the temperature of the water is gradually increased, and the gaps between adjacent prefabricated members are smaller, so that the heat dissipation of the prefabricated members is slower, the increase of the water temperature is quickened, the temperature difference between the top and the bottom of the prefabricated members is larger, and the larger water temperature difference can have the following adverse effects on the prefabricated members: (1) non-uniform intensity distribution of the preform: the hydration reaction speeds of different parts of the prefabricated member are inconsistent due to different water temperatures, the hydration reaction speed is high at one end with high water temperature, and the strength is rapidly increased; the hydration reaction at one end with low water temperature is slow, and the strength is relatively slow to increase, so that the integral strength of the prefabricated member is unevenly developed, and the structural performance of the prefabricated member is affected; (2) non-uniform shrinkage of the preform: the hydration reaction of one end with high water temperature is quick, and the shrinkage is large; the hydration reaction of one end with low water temperature is slow, the shrinkage is small, and the uneven shrinkage easily causes the prefabricated member to generate bending deformation and even cracking; (3) can cause an uneven internal stress distribution of the preform: shrinkage differences caused by temperature differences can produce uneven stress distribution inside the prefabricated part, larger shrinkage at the bottom is limited by smaller shrinkage at the top, so that tensile stress is produced, compressive stress is produced at the top, and when the stresses exceed the tensile or compressive strength of concrete, cracks can be initiated, so that the structural integrity and bearing capacity of the prefabricated part are affected.
