DETAILED DESCRIPTION

[0020] The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0021] Embodiment

[0022] As shown in Figs. 1-3 Fig. 1 is a structural schematic diagram of a concrete heat preservation mold plate in the intelligent concrete heat preservation and curing template according to the present application. The intelligent concrete heat preservation and curing template comprises a heat preservation template part and a power supply control part. The power supply control part is used for controlling the temperature of the heat preservation template part.

[0023] The heat preservation template part comprises two concrete heat preservation mold plates 1 located at both sides. The concrete heat preservation mold plate 1 comprises two side plates. The mold plate close to the concrete side is an inner side plate 3. The surface of the inner side plate 3 directly contacting the concrete is a high-thermal-conductivity material layer, which is an aluminum-plated material layer in this embodiment, and can also be copper in other embodiments. The other part of the inner side plate 3 is a low-thermal-conductivity material layer, which can facilitate heat conduction to the concrete. The mold plate close to the air side is an outer side plate 4, which is composed of a low-thermal-conductivity material layer, which can effectively reduce the conduction of solution temperature to the air. The inner side plate 3 and the outer side plate 4 are connected together through a metal material 2, forming a complete closed side plate. The connection mode of the metal material and the side plate can be welding. The metal material adopts a low-thermal-conductivity material, which is similar to the low-thermal-conductivity material layer, and can adopt a low-thermal-conductivity alloy metal material such as titanium alloy. The two concrete heat preservation mold plates 1 can be fixedly connected through a connecting piece or movably connected according to the needs of the use scene.

[0024] The concrete heat preservation mold plate 1 has a hollow inner cavity 5. A plurality of heating rods 6 are installed in the inner cavity 5. The heating rods 6 are uniformly distributed in the inner cavity 5, and the distribution density can be adjusted according to the heating power of the heating rods 6. When the heating power is high, the distribution density can be reduced; when the heating power is low, the distribution density can be increased. In this embodiment, the heating rods 6 are inserted from the top of the concrete heat preservation mold plate 1, and the heating part thereof extends into the interior of the concrete heat preservation mold plate 1. The interface of the insertion needs to be sealed and insulated. The inner cavity 5 is filled with a solution with high specific heat capacity and low thermal conductivity, such as pure water or high-concentration calcium chloride solution. The heating rods 6 can heat the solution in the inner cavity 5 when powered on.

[0025] The power supply control part comprises a temperature sensor 7. In the embodiment, the temperature sensor 7 is inserted from the bottom of the concrete heat preservation mold plate 1, and the interface where the temperature sensor 7 is inserted needs to be sealed and insulated. The temperature sensor 7 is connected with the power supply controller 9 through an information transmission wire 8, and is used to transmit temperature data to the power supply controller 9. The temperature sensor 7 has high sensitivity, and can effectively transmit solution temperature information to the power supply controller 9. The power supply controller 9 is connected with the heating rod 6 through a power supply wire, and is used to supply power to the heating rod 6. The power supply controller 9 is also connected with an electric plug 10 through a wire, and is used to connect an external power supply. The power supply controller 9 adopts an existing device, and is used to control the working state of the heating rod 6 according to the comparison result of the preset temperature range and the temperature signal. The specific structure of the power supply controller 9 is not within the protection scope of the utility model.

The predetermined temperature range in the power supply controller 9 can be set according to the concrete suitable strength development temperature. After the concrete is continuously heat preserved to the required form removal and maintenance time, the mold can be removed.

[0027] The intelligent concrete heat preservation and maintenance mold plate can heat the liquid in the concrete heat preservation mold plate to achieve the heat preservation effect on the concrete temperature, especially in the low-temperature environment such as winter, and can effectively alleviate the problems of slow concrete strength development and long form removal time.
