Description

Technical Field

[0001] The utility model belongs to the technical field of concrete curing, and particularly relates to a curing blanket for mass concrete. Background Art

[0002] The strength, durability and impermeability of concrete all depend on the hydration reaction of calcium hydrate to generate calcium silicate hydrate, thereby forming a hardening reaction in the concrete. In order to ensure that the cement paste reaches the optimal water-cement ratio during the curing period, a certain amount of water needs to be added to the cement paste. Therefore, various measures should be taken to avoid the evaporation of concrete moisture caused by evaporation or other reasons. In winter, since water freezes below 0 degrees Celsius, ice crystals are generated, which destroys the hardening reaction of the concrete and reduces the strength of the concrete. The hydration reaction of the concrete lasts for 14 days after pouring, and the strength of the concrete can reach 70%. Therefore, in order to ensure that the final strength of the concrete is at least 70%, the water content in the concrete should be guaranteed for at least 14 days. To achieve this goal, a curing cover is usually used to cure the concrete, aiming to prevent the evaporation of water and ensure the water content in the concrete. However, ordinary covers are generally plant (wheat straw, rice straw) woven fabrics, which have disadvantages such as easy evaporation of water in summer and easy icing in winter.

The insulating layer 2 is arranged at the uppermost part in the blanket body 1. The insulating layer 2 is an insulating cotton blanket. The insulating layer 2 is connected to the blanket body 1 by bonding or by sewing.

[0025] As Figure 1 and Figure 2 shown in the figure, the heating layer 3 includes an electric heating element 31 and a first base cloth 32. The first base cloth 32 is rectangular. The first base cloth 32 is connected to the blanket body 1 or the insulating layer 2 by bonding or by sewing. The electric heating element 31 is connected to the first base cloth 32. The electric heating element 31 is arranged in an S shape (or a square shape) on the first base cloth 32, so as to heat the whole surface of the curing blanket evenly. In this embodiment, the electric heating element 31 is a self-limiting temperature electric heating tape, such as the low-temperature self-limiting temperature electric heating tape produced by Tianjin Yatalong Thermal Control Technology Co., Ltd., model: QDTV-P / J-26-220, rated voltage 220V, power 26W / m, maximum maintaining temperature 65°C, maximum bearing temperature 105°C, maximum use length 100m.

The outermost layer is an outer sheath made of polyolefin material, and the waterproof effect is good.

[0026] As Figure 1 and Figure 3As shown, the insulating layer 4 is disposed below the heating layer 3. The insulating layer 4 is connected to the first base cloth 32 of the heating layer 3 by an adhesive method. The insulating layer 4 is a PVC cloth, which can achieve good insulation and waterproof effects, preventing the water spraying layer 5 below from affecting the electric heating element 31 above. The water spraying layer 5 includes a water supply pipe 51, a solenoid valve 52, and a second base cloth 53. The second base cloth 53 is rectangular. The second base cloth 53 is connected to the blanket body 1 by an adhesive method or a sewing connection method or is connected to the insulating layer 4 by an adhesive method. In this embodiment, the water supply pipe 51 is a plastic hose. The water supply pipe 51 is connected to the lower surface of the second base cloth 53. The water supply pipe 51 is arranged in an S shape (it can also be arranged in a square shape). A plurality of limiting bands 531 are connected to the second base cloth 53. The limiting bands 531 straddle both sides of the water supply pipe 51. The position of the water supply pipe 51 is restricted by the plurality of limiting bands 531. A plurality of nozzles 511 are provided on the side surface of the water supply pipe 51 (the nozzles 511 can also be provided on the bottom surface of the water supply pipe 51 as needed). The plurality of nozzles 511 spray water sideways. When the nozzles are arranged downward, they are sometimes blocked. The nozzles 511 spraying water sideways will not be blocked by the sundries below. The solenoid valve 52 is disposed at the inlet end of the water supply pipe 51 to control the on-off of the water supply pipe 51. The inlet end of the water supply pipe 51 is a quick water pipe joint, which is convenient to connect to the external water circuit during use.

[0027] As Figure 1 and Figure 3 shown, a moisture retaining layer 6 is detachably connected to the bottom surface of the blanket body 1. A plurality of hook tapes 81 of the magic tape are provided on the bottom surface of the blanket body 1. The plurality of hook tapes 81 of the magic tape are distributed at the edge of the opening on the bottom surface of the blanket body 1. A plurality of loop tapes 82 of the magic tape corresponding to the hook tapes 81 of the magic tape are provided on the moisture retaining layer 6.

Thus, the moisture retaining layer 6 is detachably connected to the blanket body 1 through the magic tape. The moisture retaining layer 6 is replaceable. In this embodiment, the moisture retaining layer 6 is a moisture retaining blanket. The material of the moisture retaining blanket is geotextile or felt, which can achieve good heat preservation and moisture retention effects and can be used in cooperation with the water supply pipe 51 to keep the concrete moist.

The temperature and humidity sensor includes a probe 71 and a temperature and humidity transmitter 72. A groove corresponding to the probe 71 is provided on the bottom surface of the blanket body 1. The probe 71 is placed in the groove. The temperature and humidity transmitter 72 is connected to the probe 71 through an electric wire. The temperature and humidity transmitter 72 is disposed on the front surface of the blanket body 1. The temperature and humidity sensor adopts an existing sensor, such as the temperature and humidity sensor produced by Shanghai Yijie Automation Technology Co., Ltd. The power supply is 220V, the output current is 4 - 20mA, the output voltage is 0 - 5V, the accuracy is: humidity ±3%RH, temperature ±0.5°C, the working temperature of the probe is -40°C - 80°C, the IP65 protection level, resistant to rain and dust, and the probe is a waterproof probe.
