Description

Technical Field

[0001] The present application relates to the technical field of concrete curing, and in particular to a concrete curing device for concrete preparation. Background Art

[0002] As the most basic and indispensable material in the field of modern construction, the stability of concrete performance and the guarantee of quality are crucial to the safety and durability of the entire project. The performance and quality of concrete are closely related to its raw materials, mix ratio and preparation process, and the curing process also plays a pivotal role. Therefore, the research and development and application of concrete curing equipment for concrete preparation are of great significance to improving the overall quality of concrete projects.

[0003] When concrete is just poured, the cement inside it reacts chemically with the water, gradually hardening into a solid structure. To ensure that this process goes smoothly, the concrete needs to maintain a certain humidity. Therefore, workers will use water pipes or special spraying equipment to spray clean water on the surface of the concrete at regular intervals. In this way, the water can penetrate into the surface of the concrete, providing the necessary moisture for the chemical reaction inside it, and also helping to prevent cracks and strength loss caused by premature drying of the concrete.

[0004] However, in a construction environment with low temperatures, the newly poured concrete will freeze under the influence of low temperatures, which will stop the hydration inside the concrete. Hydration is a key factor in the formation of concrete strength. It involves the chemical reaction between cement and water to produce compounds that are essential for strength. Once hydration is blocked, the internal structure of the concrete will not be fully developed, and the concrete surface will become brittle, reducing the molding strength of the concrete.

[0036] When in use, firstly, the main rod 1 is pulled to drive the rectangular mounting frame 2 to approach the concrete wall to be poured, and the rectangular mounting frame 2 drives the abutting roller 5 to form rolling abutment with the concrete wall to be poured, and at the same time, one end of the rectangular mounting frame 2 is made to push the inner rod 13 around the hinge axis to squeeze the ejection spring 14 to produce contraction deformation, and the inner rod 13 is pushed to move along the length direction of the sleeve rod 12 by utilizing the rebound characteristics of the ejection spring 14, and at the same time, the inner rod 13 pushes the rectangular mounting frame 2 to drive the abutting roller 5 to form a parallel state with the concrete wall to be poured;

[0037] Then, an external water source is introduced into the interior of the nozzle 3 through the connecting hose 4, and sprayed toward the wall to be watered through the nozzle 3. Then, by starting the air pump 9 and the electric heating wire 8, the air pump 9 draws external air into the interior of the air duct 6 through the air delivery hose 10, and then the air inside the air duct 6 is sprayed toward the wall through the air jet 7. At the same time, the air sprayed toward the wall through the air duct 6 contacts the electric heating wire 8 and is quickly heated by the electric heating wire 8. At the same time, the main rod 1 is driven to drive the rectangular mounting frame 2 to push the resistance roller 5 to move along the concrete wall to be watered, so as to facilitate the output of heated air to the concrete wall through the air jet 7 in a low temperature environment, thereby utilizing the heated air to increase the temperature of the concrete wall, ensuring its normal solidification and drying, and preventing freezing and strength reduction caused by low temperature.

[0049] Then, an external water source is introduced into the interior of the nozzle 3 through the connecting hose 4, and sprayed toward the wall to be watered through the nozzle 3. Then, by starting the air pump 9 and the electric heating wire 8, the air pump 9 draws external air into the interior of the air duct 6 through the air delivery hose 10, and then the air inside the air duct 6 is sprayed toward the wall through the air jet 7. At the same time, the air sprayed toward the wall through the air duct 6 contacts the electric heating wire 8 and is quickly heated by the electric heating wire 8. At the same time, the main rod 1 is driven to drive the rectangular mounting frame 2 to push the abutment roller 5 to move along the concrete wall to be watered.

[0050] Then, when the temperature rises and there is no need to output hot air to the concrete wall through the air jet 7, the driving screw 20 is driven to rotate by turning the driving knob 21, and the driving screw 20 is driven to form a threaded connection with the transmission rack 18, and at the same time, the transmission rack 18 drives the transmission slider 17 to move along the length direction of the transmission slide groove 16, and the transmission rack 18 is meshed with the transmission gear 15, so that the transmission gear 15 drives the air duct 6 to rotate, and the air duct 6 drives the air jet 7 to rotate toward the cover plate 19, and at the same time, the air duct 6 drives the air jet 7 to squeeze the sealing rubber pad 22 to deform, and the sealing rubber pad 22 is filled between the cover plate 19 and the air jet 7, so that the sealing rubber pad 22 forms a sealed cover on the inside of the air jet 7, effectively reducing the influence of water flow entering the air duct 6 through the air jet 7 on the electric heating wire 8.
