Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, in particular to a detachable curing box and a concrete curing device. Background Art

[0002] With the rapid development of my country's economic construction, the scale of urban construction is expanding, and the requirements for concrete construction are getting higher and higher. When the outdoor daily average temperature is below 5℃ for 5 consecutive days, or the minimum temperature is stable below -3℃ for 5 consecutive days, winter construction measures should be taken for concrete projects. Based on the long construction period of concrete, most projects will go through the process of winter construction, and how to keep warm and maintain has become a concern for winter construction.

[0003] At present, the concrete curing methods for winter construction include negative temperature curing, steam heating, heat storage, electric heating, greenhouse, stove heating, etc., but each has its own defects. The concrete strength increases slowly under negative temperature curing. The steam heating method has large heat loss, high cost, unsatisfactory working conditions and requires special boiler equipment and sites. The heat storage method is not suitable for very low temperature conditions and the strength increases slowly. The electric heating method consumes relatively large amounts of electricity. The greenhouse method is very expensive and takes up a lot of time. The stove heating method releases CO 2 It will carbonize the surface of newly poured concrete and affect its quality. Infrared curing is a new type of heating curing method, which uses the invisible infrared rays emitted by the heat source to heat the air or directly radiate and penetrate, transfer heat energy to the concrete, and perform sealed radiation heating on the concrete to increase its temperature and strength. It is suitable for the curing of various concrete structures and components and has great application advantages.

[0004] Existing infrared heating curing devices for concrete, such as the Chinese patent application number 201110316798.7, "Environmentally friendly and energy-saving far-infrared automatic temperature control concrete curing system", use infrared curing devices to perform construction and curing on concrete components, better control the temperature and humidity of concrete specimens, and effectively improve the strength of concrete specimens in winter. However, the box of this device is a fixed structure, and the fixed length and width determine the limited curing space, which cannot perform large-scale thermal insulation curing work. The curing device has poor flexibility. When the number of concrete specimens in the box increases, the curing work becomes difficult and comprehensive curing cannot be performed, which results in the concrete strength failing to meet the design requirements.
