[0033] The clamping grooves 101 are fixedly connected with the clamping columns 102, which facilitate the clamping of the connecting buckles 103, so as to splice the pair of outer frames 1.

[0034] In addition, the side wall of the outer frame 1 away from the clamping grooves 101 is fixedly connected with a pair of connecting buckles 103, which are clamped on the pair of clamping columns 102, respectively. By clamping the connecting buckles 103 on the clamping columns 102, the pair of outer frames 1 can be spliced to preserve and maintain the large-area concrete.

[0035] Specifically, one side wall of the outer frame 1 is provided with a first magnetic strip 104 adjacent to the clamping column 102. The side wall of the outer frame 1 away from the first magnetic strip 104 is provided with a groove, and a second magnetic strip 105 is installed in the groove, which is attracted to the first magnetic strip 104 on the side wall of the other outer frame 1. By the mutual attraction between the second magnetic strip 105 and the first magnetic strip 104, the mutual splicing of multiple outer frames 1 can be realized, as shown in Figure 1 , so as to preserve and maintain the concrete.

[0036] Please refer to Figures 1 to 4 , the heat release box 2 is embedded on the outer frame 1, and the heat release box 2 is used to accommodate the quicklime and water.

[0037] The heat release box 2 is a cuboid structure, and the length of the heat release box 2 is less than the width of the outer frame 1.

[0038] In addition, the inner wall of the heat release box 2 is provided with a waterproof cloth and a heat-resistant polyester fiber layer, which ensures that the hydrolysis reaction of the quicklime and water can proceed normally, so as to utilize the heat generated by the hydrolysis reaction of the quicklime and water to preserve and maintain the concrete.

[0046] The lower side of the straw mat 4 is provided with a sack layer 401, and the sack layer 401 is arranged on the lower side of the heat distribution pipe 301. The sack layer 401 can further improve the insulation and curing effect of the concrete, and also can ensure that the heat released by the heat distribution pipe 301 can be used to insulate and cure the concrete, so that the concrete is not easily affected by low temperature.

[0047] In specific use, when the external temperature is low, for example, when the external temperature is lower than 5℃, a plurality of outer frames 1 are spliced, that is, the connecting buckle 103 is clamped on the clamping column 102 of another outer frame 1, and the first magnetic stripe 104 is attracted to the second magnetic stripe 105 on the side wall of another outer frame 1, and so on, so as to obtain the insulation and curing structure as shown in Figure 1 .
