DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0031] A concrete curing membrane that resists external disturbances, such as Figure 1 As shown, it includes a curing film 2, and the curing film 2 includes, from top to bottom, an outermost film 2-1, a middle film 2-2 and a lowermost film 2-3.

[0032] like Figure 2 As shown, the outermost film 2-1 has a transparent resin layer 2-1-3 inside, and the resin layer 2-1-3 is wrapped by an acrylic protective film 2-1-1 outside. The acrylic protective film 2-1-1 is a transparent, weather-resistant protective film that can protect the resin layer 2-1-3 from being damaged by external factors such as ultraviolet rays, acid rain, and sandstorms. The acrylic protective film 2-1-1 on the top of the resin layer 2-1-3 can protect the inside of the curing film 2 and avoid the influence of external factors on the curing film 2, such as the influence of hot summer and high temperature, cold winter and low temperature, rain on rainy days, and the influence of air flow on the curing temperature and humidity.

[0033] A plurality of pillars 2-1-4 are arranged between the resin layer 2-1-3 and the acrylic protective film 2-1-1 above, so that an air layer 2-1-2 is formed between the top of the resin layer 2-1-3 and the acrylic protective film 2-1-1, and a plurality of hemispherical glass bodies 2-1-5 are embedded inside the resin layer 2-1-3; Figure 3 As shown, a reflective layer 2-1-8 is provided inside the glass body 2-1-5, and when light is irradiated on the surface, reflected light will be generated to achieve a reflective cooling effect. The glass body 2-1-5 is in a hemispherical shape, which can meet the requirements of light reflection and is easier to be firmly connected with the resin layer 2-1-3 than a spherical shape, and it also saves more materials.

[0034] When the external environment cools down, the gas in the air layer 2-1-2 can slowly transfer the temperature, play a heat insulation role, and prevent the internal concrete from rapidly cooling down. The thickness of the air layer 2-1-2 is 1mm~2mm. Exceeding this range will increase the overall thickness, resulting in increased costs and waste of resources; if it is too small, it will be difficult to play an effective heat insulation role.

[0035] The lower surface of the acrylic protective film 2-1-1 at the bottom of the resin layer 2-1-3 is bonded together by the adhesive 2-1-6 and the backing paper 2-1-7, and the backing paper 2-1-7 and the middle layer film 2-2 are fixedly connected; the total thickness of the outermost film 2-1 is 3mm~4mm, and a thickness greater than this range will increase the cost and increase the thickness of the entire film.

[0036] Water pipes 2-4 are evenly distributed inside the middle layer membrane 2-2 to evenly supply water to the middle layer membrane 2-2; the middle layer membrane 2-2 is a planar water-saving and moisturizing maintenance membrane, and the wall of the water pipes 2-4 is evenly provided with holes. When water is supplied to the water pipes 2-4 by a water pump 7, the water in the water pipes 2-4 flows out of the holes and is evenly absorbed by the middle layer membrane 2-2.

[0037] In some embodiments, one end of the water pipe 2-4 is connected to the water supply tank 6 through the water inlet conduit 4, and a water pump 7 and a flow meter 5 are installed on the water inlet conduit 4. The other end of the water pipe 2-4 is connected to the collector 15, and the bottom of the collector 15 is connected to the water supply tank 6 through the water outlet conduit 12. The excess water in the water pipe 2-4 flows into the collector 15 and is transported to the water supply tank 6 through the water outlet conduit 12. A filtering and purification device 8 is installed at the water outlet end of the water outlet conduit 12. The water flowing out of the water pipe 2-4 is collected and then flows through the water outlet conduit 12, and then flows back to the water supply tank 6 through the filtering and purification device 8. The water is filtered by the filtering and purification device 8, and the filtered water enters the water pipe 2-4 through the water pump 7 to avoid impurities in the water from blocking the water pump 7, forming a cycle, and saving building water.

[0038] In some embodiments, the middle layer film 2-2 uses a YHM-DP series 07P flat water-saving and moisturizing curing film, which uses a polymer absorbent material as the core and a plastic film as the carrier. It can absorb water molecules 200 times its own weight; the curing film weighs 25g / m 2 The film thickness is 5~10mm and contains high-efficiency moisturizing crystals. After absorbing water and swelling, the material becomes transparent crystals, turning liquid water into solid water, and then penetrates into the curing surface continuously through capillary action. At the same time, it continuously absorbs the evaporated water of the curing body during the hydration heat process of the concrete, ensuring the relative humidity of the curing body surface during a curing period.

[0039] The bottom membrane 2-3 is evenly laid on the surface of the curing concrete 1, and the water in the middle membrane 2-2 passes through the bottom membrane 2-3 to reach the surface of the curing concrete 1. A temperature and humidity sensor 13 is provided between the bottom membrane 2-3 and the surface of the curing concrete 1, which is used to measure the temperature and humidity of the surface of the curing concrete 1 in real time.

[0040] In some embodiments, the bottom film 2-3 is a water-filtration and water-permeable blanket made of non-woven fabric. Under the gravity of the upper part, even if the surface of the curing concrete 1 is uneven or sloped, it can be closely and evenly covered on the surface of the curing concrete 1; the bottom film 2-3 absorbs water from the middle film 2-2, and as the curing time goes by, the absorbed water is evenly provided to the curing concrete 1, which also has the function of cold protection and warmth preservation. The thickness of the bottom film 2-3 is 2mm~5mm. If it is too thick, it will increase the cost and the thickness of the entire film. If it is too thin, it will affect the covering effect on the surface of the curing concrete 1.

[0041] During use, the water in the water pipe 2-4 enters the middle layer membrane 2-2 through the holes. The water output of the water pump 7 is adjusted according to the humidity collected by the temperature and humidity sensor 13, so that the flow rate displayed by the flow meter 5 is within the appropriate range, and then the amount of water entering the water pipe 2-4 is adjusted, and the amount of water replenished into the middle layer membrane 2-2 is adjusted, thereby adjusting the curing humidity. The water temperature in the water supply tank 6 is adjusted according to the temperature collected by the temperature and humidity sensor 13, thereby adjusting the curing temperature. The bottom layer membrane 2-3 transfers the heat in the curing concrete 1 upward to the water pipe 2-4, and the water pipe 2-4 then brings the excess heat to the collector 15 through water, achieving the effect of dissipating the heat generated in the curing concrete 1.

[0042] The method for using the above-mentioned concrete curing film that resists external interference is carried out according to the following steps:

[0043] S1: laying of curing film 2; according to the specific situation of the concrete 1 that needs to be cured after pouring, the prepared curing film 2 is laid as required, and after the external related lines are connected, a complete curing system is formed.

[0044] S2: Inspection before curing: Check whether the circuit parts of each test device are intact and usable, and prepare various devices and instruments required for curing concrete 1.

[0045] S3: Curing temperature control; according to the temperature information collected by the temperature and humidity sensor 13, the temperature of the curing concrete 1 is adjusted by adjusting the water temperature in the water supply tank 6.

[0046] S4: Curing humidity control; according to the humidity information collected by the temperature and humidity sensor 13, the amount of water entering the water pipe 2-4 is adjusted by the water pump 7, thereby adjusting the humidity of the curing concrete 1.

[0047] S5: curing water recycling; the excess water in the water pipe 2-4 flows into the collector 15, is transported through the water outlet conduit 12, and enters the water supply tank 6 after being processed by the filtration and purification device 8, forming a cycle and making full use of water resources.

[0048] This practicality keeps the concrete surface moist in hot summer and prevents the temperature of the concrete surface from rising due to external sunlight; in cold seasons, it can insulate and maintain the temperature of the concrete surface relatively stable, greatly reducing the difficulty of temperature and humidity control and improving the quality of concrete maintenance. In addition, in practical applications, it overcomes the problem that it is difficult to cover the concrete surface with water for maintenance when the concrete surface is uneven or sloping.

[0049] Each embodiment in this specification is described in a related manner, and the same or similar parts between the embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
