Description

Technical Field

[0001] The invention belongs to the technical field of engineering construction, and in particular relates to a concrete temperature control device. Background Art

[0002] Concrete is widely used in construction projects, covering areas from infrastructure construction to residential buildings, commercial buildings, bridges, tunnels and roads. As a building material, it plays an irreplaceable role in modern architecture.

[0003] During the concrete hardening process, especially in hot summer environments, when the concrete surface is exposed to high temperatures for extended periods, the large temperature difference between the interior and exterior can generate temperature stress, which in turn causes cracks in the concrete. These cracks not only reduce the durability of the structure and increase repair costs, but can also pose safety risks to the building structure. In existing technologies, construction workers often resort to spraying the concrete surface to mitigate the temperature difference between the interior and exterior.

[0004] However, when construction workers spray the concrete surface, they often adopt a uniform spraying method. Although this method can alleviate the difference between the internal and external temperatures of the concrete to a certain extent, the uniform spraying cannot accurately adjust the temperature of the area where the concrete needs to be temperature controlled. Moreover, the spraying amount is also an empirical value and cannot be accurately quantified. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a concrete temperature control device to solve the above problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a concrete temperature control device, comprising a mobile frame, on which a spray assembly for spraying a concrete body is slidably provided, a supply assembly for providing a spray medium to the spray assembly is provided on one side of the spray assembly, and the concrete temperature control device further comprises:
