Description

Technical Field

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

[0002] Precast concrete components are concrete components that are prefabricated in a factory or construction site and then transported to the construction site for installation. Precast concrete components can improve the efficiency of construction, improve the quality of building components, save labor, maintain stable quality, and effectively reduce costs. Precast concrete components have been widely used.

[0003] At present, after the concrete is twisted into the formwork, the concrete components inside the formwork need to be cured. The conventional curing method is to lay a film on the surface of the formwork and spray water on the surface of the formwork at an appropriate time, or spray a curing agent on the surface of the concrete. However, due to the hydration heat inside the concrete, a large amount of water inside the concrete will be volatilized. Even if a film or other covering material is laid on the surface, it is not easy to intercept the volatilized water. Although it can be improved by spraying water, the number of water spraying required is large, which not only causes a waste of water resources, but also increases the workload.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0022] Reference Figure 1-3 A dry curing device for precast concrete components comprises a box body 1, a lifting plate 2 is arranged inside the box body 1, and a template mounting seat 3 is installed on the end surface of the lifting plate 2, a group of sliding rods 4 are fixedly installed on both sides of the upper end of the lifting plate 2, and the rod wall of each sliding rod 4 is slidably connected to the top of the box body 1, an opening is arranged at the top of the box body 1 between the two groups of sliding rods 4, and a sealing cover plate 5 is arranged above the opening, a groove 6 is arranged at the lower end of the sealing cover plate 5, a condensing plate 7 is installed inside the groove 6, a plurality of semiconductor refrigeration plates 8 are fixedly inserted at the bottom of the groove 6, and the cold end of each semiconductor refrigeration plate 8 is in contact with the upper end of the condensing plate 7, and the hot end of each semiconductor refrigeration plate 8 is arranged on the outside of the groove 6.

[0023] A water inlet pipe 9 is fixedly connected to one side of the bottom of the groove 6, and a plurality of spray heads 10 are fixedly connected to the lower end of the condensation plate 7, and each spray head 10 is connected to the interior of the groove 6. Water can be introduced into the interior of the groove 6 through the water inlet pipe 9 and sprayed out through each spray head 10, so that the precast concrete components can be appropriately sprayed with water in a timely manner to ensure the maintenance effect.

[0024] A U-shaped plate 11 is fixedly installed on the upper end of the sealing cover plate 5, and an air cavity 12 is arranged inside the U-shaped plate 11, a mounting sleeve 13 is fixedly inserted into the upper cavity wall of the air cavity 12, and a cooling fan 14 is fixedly installed inside the mounting sleeve 13, and a plurality of conical air outlet holes 15 are provided on the lower cavity wall of the air cavity 12. Through the operation of the cooling fan 14, the air flow at the hot end of each semiconductor refrigeration plate 8 can be increased, so that the temperature at the hot end of each semiconductor refrigeration plate 8 can be timely reduced.

[0025] Connecting hoses 16 are fixedly connected to both sides of the end surface of the lifting plate 2, and transparent hollow panels 17 are fixedly installed on the two outer walls of the box body 1, and the two transparent hollow panels 17 are connected to the connecting hoses 16 on the same side. Part of the water that falls back may fall on the lifting plate 2. At this time, the water will enter the corresponding transparent hollow panel 17 through the connecting hoses 16. When personnel observe that there is a lot of water inside the transparent hollow panel 17, it means that a lot of water has not been effectively returned to the concrete at this time. Therefore, the precast concrete components inside the box body 1 should be sprayed with water for maintenance in time to ensure the maintenance effect. A drainage hole is provided at the bottom of the transparent hollow panel 17, and the internal thread of the drainage hole is blocked, which can facilitate the discharge of the water inside the transparent hollow panel 17.

[0026] The lower end of the condensation plate 7 is integrally formed with a plurality of protrusions 18, through which the condensed water droplets can be gathered into droplets and the contact area between the water droplets and the condensation plate 7 can be reduced, thereby facilitating the water droplets to fall.

[0027] A group of hydraulic cylinders 19 are fixedly connected to both sides of the top of the box body 1, and the output end of each hydraulic cylinder 19 is fixedly connected to the end surface of the lifting plate 2. When the hydraulic cylinder 19 is working, it can drive the lifting plate 2 to move up and down stably.

[0028] A flexible film sleeve 20 is fixedly arranged between the lifting plate 2 and the inner top of the box body 1, and the template mounting seat 3 is arranged on the inner side of the flexible film sleeve 20. The flexible film sleeve 20 can be used to enclose and reduce the space between the lifting plate 2 and the box body 1, thereby reducing the range of moisture escape.

[0029] In the present application, when in use, the prefabricated component template poured with concrete is installed on the template mounting seat 3, and then the template mounting seat 3 is used to drive the prefabricated component template to move down into the interior of the box body 1 through the lifting plate 2. After the lifting plate 2 is lowered into place, the sealing cover plate 5 will press and seal the opening on the top of the box body 1, thereby reducing the evaporation and escape of moisture. At the same time, during the curing process of the precast concrete, the semiconductor refrigeration plate 8 is started. The semiconductor refrigeration plate 8 can transfer the heat of the condensation plate 7 from the cold end to the hot end, so that the surface temperature of the condensation plate 7 is maintained at a low level. When the volatile moisture encounters the low-temperature condensation plate 7, the volatile moisture will re-condense into water droplets and fall back from the condensation plate 7 to the concrete surface, thereby reducing the waste of moisture as much as possible while conducting away the hydration heat generated during the concrete curing, thereby reducing the number of water spraying curing times.

[0030] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
