Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated concrete component maintenance, and in particular relates to a stacking spraying device for prefabricated concrete staircase components. Background Art

[0002] After the prefabricated concrete staircase components are steamed and demoulded, they are usually stored in open-air three-dimensional stacking in the factory area. The number of stacking layers is usually about 5, and wooden pads are often used to support and divide the layers. Not only is the small space not conducive to watering and curing, but the inaccurate placement can easily cause uneven force on the components and cracks. At the same time, affected by the characteristics of concrete itself, environmental temperature and humidity and other factors, the components also need to be continuously watered and cured during storage.

[0003] However, for the three-dimensional stacking mode, conventional watering and curing can only maintain the upper surface of the component, while the lower surface remains dry. In addition, extensive watering and curing is not only time-consuming and labor-intensive, resulting in excessive waste of water resources, but also unable to achieve real-time dynamic and timely maintenance according to the water demand of the component age and the actual environmental conditions.

[0004] Therefore, when the existing prefabricated staircase components are stacked and stored, it is impossible to achieve real-time dynamic and timely maintenance according to the water demand of the components at the age and the actual environmental conditions. Summary of the invention

[0005] The present invention provides a stacking spray device for concrete stair prefabricated components, which is used to solve the problem in the prior art that when prefabricated stair components are stacked and stored, real-time dynamic and timely maintenance cannot be achieved according to the water demand of the components due to their age and the actual environmental conditions.

While meeting the requirements of stacking and storage in the factory area, it can also be hoisted and transported with the prefabricated staircase components, reducing the risk of damage to the prefabricated staircase components caused by multiple hoisting alone; combined with the water supply unit, it can achieve the combination of three-dimensional storage and all-weather automatic spraying maintenance, while also achieving the purpose of saving manpower and material resources and rationally utilizing water resources; and the atomizing nozzle is arranged between the layers of the prefabricated staircase components together with the supporting structure.
