Specific implementation mode
In order to make the purpose of the present invention, technical solution and advantage be more clearly understood, below in conjunction with drawings and examples,
The present invention will be described in further detail.It should be understood that specific embodiment described herein is only used for explaining this hair
It is bright, it is not intended to limit the present invention.
Embodiment one：
As shown in Figure 1, the concrete curing equipment in the present embodiment includes：Moisturizing layer 1 is covered in 2 surface of concrete；
Air bag component is that can be filled with the closed structure of gas, for hindering the sky with around of the concrete 2 after being filled with gas
Heat exchange occurs between gas；And temperature control equipment, the air bag component 3 is connected, described fill is filled with for adjusting
Gas temperature in gas air bag component 3.
Specifically, as shown in Fig. 2, the moisturizing layer 1 includes the self-adhering type adhered layer 11 ', absorbing membrane 11, nothing being sequentially overlapped
Woven fabric 12 and plastic foil 13, wherein the adhered layer 11 ' is bonded with 2 surface of the concrete, and the adhered layer 11 ' for
Hydrone passes through；Preferably, one layer of water-absorption particle 14, the water suction are additionally provided between the non-woven fabrics 12 and plastic foil 13
Film 11 and/or water-absorption particle 14 are that polymer absorbent material is made, and the plastic foil 13 is impermeable layer structure, can be polychlorostyrene
One or more of ethylene, polyethylene, polypropylene, polystyrene are made.
The moisture film 1 is nontoxic self-adhering type moisture film, absorbing membrane 11 made of polymer absorbent material and/or is inhaled
The moisture of absorbable 200 times of the dead weight of particle water 14, and liquid water is become solid water, then by the effect of capillary to coagulation
Native surface penetration, while the evaporation water that concrete generates during the heat of hydration is constantly absorbed, concrete surface moistening is kept, this
Outside, outermost fluid-tight plastic foil moisture losses for further preventing concrete surface of page 13, the moisturizing in the present embodiment
Film 1 may make concrete surface to keep moisture state in 28 days, and can effectively reduce concrete surface and generate desciccation crack.
Further, such as Fig. 1, shown in 3, the air bag component includes：By gas impermeable material (in such as plastics, rubber
One or more) made of, the utricule 31 for being filled with gas, it is preferred that the utricule 31 can be integrally formed, or by not
It is formed with part by the forms such as suturing, being bonded；And at least one charger 32 for being inflated into the utricule 31
(such as air blower).
On this basis, the temperature control equipment includes：At least one temperature sensor 4 is covered on the coagulation
Native 2 surfaces, the temperature data for detecting 2 surface of concrete in real time；
And heating device 33 (such as air duct type electric heater), each temperature is connected in a manner of wire/wireless respectively
It spends sensor 4 and the charger 32 is connected to by pipeline, for being adjusted according to the temperature data on 2 surface of the concrete
The temperature for the gas being filled with into the utricule 31.
The specific course of work is that the charger 32 is for generating gas, and the gas is entered by pipeline
In heating device 33, meanwhile, the temperature data on 2 surface of concrete detected is sent to heating device 33 by temperature sensor 4,
Heating device 33 adjusts the temperature for entering the gas in heating device 33 according to the temperature data in real time so that the gas
Temperature be adjusted to the temperature on 2 surface of concrete it is almost the same after entered in utricule 31 by pipeline again, thus, it is ensured that
2 surface temperature of concrete and air bag component internal gas temperature are almost the same, avoid concrete surface due to excessive temperature differentials
It radiates too fast, and then causes temperature difference crack in concrete surface.
In addition, for ease of the fixation air bag component, it is made to play the heat insulation being more uniformly distributed, the utricule 31
Surface is connect by hook 34 and/or double faced adhesive tape with the moisturizing layer 1.
Air bag component is inflated after being passed through gas into the utricule 31, between concrete 2, insulating layer 1 and air to be isolated,
Thus it hinders that heat exchange occurs between the concrete 2 and surrounding air, heat insulation and preservation effect is played to concrete 2, reduce mixed
The thermal loss of solidifying soil 2, meanwhile, while passing through 1 moisturizing of moisturizing layer so that concrete 1 keeps certain water content for a long time, from
And avoid it from scattering and disappearing since moisture is too fast and surface temperature of concrete is caused to change greatly, and resulting drying shrinkage is avoided to split
Seam or contraction fissure.
