Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0027] Please refer to Figures 1-6 In the embodiment of the present application, the heating and insulation template includes a plate body 1, a first edge-sealing strip 141, and a second edge-sealing strip 142. The first edge-sealing strip 141 and the second edge-sealing strip 142 extend in the horizontal direction. A medium outlet 17 and a medium inlet 16 are provided on one side of the plate body 1. Both the medium inlet 16 and the medium outlet 17 are provided with valves 171. A heat medium circulation channel is provided in the plate body 1 for circulating the heat medium. The two ends of the heat medium circulation channel are connected to the medium inlet 16 and the medium outlet 17 respectively. Openings are provided on both sides of the plate body 1. The first edge-sealing strip 141 and the second edge-sealing strip 142 respectively block the openings on both sides of the plate body 1.

[0028] The object to be insulated 3 can be concrete or other objects. The plate 1 is mounted on the object to be insulated 3. When the valves 171 on the medium inlet 16 and the medium outlet 17 are opened, the heat medium enters the heat medium circulation channel from the medium inlet 16 and flows out from the medium outlet 17. Heat conduction occurs between the heat medium and the plate 1, controlling the temperature of the plate 1 and, in turn, regulating the curing temperature of the concrete.

[0029] In the embodiment of the present application, the plate body 1 includes a plurality of first sealing partition ribs 12 and a plurality of second sealing partition ribs 121 . The first sealing partition ribs 12 and the second sealing partition ribs 121 both extend along the longitudinal axis, which is perpendicular to the transverse axis. The first sealing partition ribs 12 and the second sealing partition ribs 121 are arranged alternately and at intervals. The heat medium circulation channel includes a plurality of longitudinal flow channels 10 extending along the longitudinal axis and a plurality of transverse connecting grooves 13 extending along the transverse axis. The plurality of longitudinal flow channels 10 and the plurality of transverse connecting grooves 13 are connected end to end in sequence. The transverse connecting groove 13 connects two adjacent longitudinal flow channels 10. A first sealing partition rib 12 or a second sealing partition rib 121 is arranged between the two adjacent longitudinal flow channels 10. One end of the first sealing partition rib 12 is connected to the first edge sealing strip 141, and a transverse connecting groove 13 is provided between the other end of the first sealing partition rib 12 and the second edge sealing strip 142; one end of the second sealing partition rib 121 is connected to the second edge sealing strip 142, and a transverse connecting groove 13 is provided between the other end of the second sealing partition rib 121 and the first edge sealing strip 141.

[0030] In the embodiment, the two outermost longitudinal flow channels 10 of the plurality of longitudinal flow channels 10 are respectively connected to the medium inlet 16 and the medium outlet 17.

[0031] In the embodiment, the longitudinal flow channel 10 includes a plurality of sub-channels 11, and the adjacent two sub-channels 11 are arranged at intervals. The plurality of sub-channels 11 are of the same size and arranged at equal intervals.

[0032] In the embodiment, the cross section of the sub-channel 11 is circular.

[0033] In the embodiment, the plate body 1 includes a first sub-plate 22 and a second sub-plate 21 stacked together, and the first sub-plate 22 and the second sub-plate 21 are integrally formed by an extrusion molding process. The second sub-plate 21 is provided with the medium outlet 17 and the medium inlet 16 on the side surface away from the first sub-plate 22. The first sub-plate 22 is used to attach to the object 3 to be kept warm and dissipate heat from the object 3 to be kept warm. The stacking direction of the first sub-plate 22 and the second sub-plate 21 is perpendicular to the plate surface of the plate body 1.

[0034] In the embodiment, the thermal conductivity of the first sub-plate 22 is greater than that of the second sub-plate 21.

[0035] In the embodiment, the thermal conductivity of the first sub-plate 22 is 1.5 W / (m·K) to 2.0 W / (m·K), and the thermal conductivity of the second sub-plate 21 is 0.13 W / (m·K).

[0036] In the embodiment, the materials of the plate body 1, the first edge sealing strip 141 and the second edge sealing strip 142 are plastic.

[0037] In the embodiment, the first edge sealing strip 141 and the second edge sealing strip 142 are hot melt welded to the plate body 1. The first edge sealing strip 141 and the plate body 1 form a hot melt welding surface 143 therebetween.

[0038] The plate body 1 is a hollow plastic template. The hollow plastic template is a plastic plate with a certain thickness and width manufactured by an extrusion molding process. The cross section of the plate is porous, and a plurality of longitudinal flow channels 10 are formed along the length direction of the plate. Meanwhile, PP material with low thermal conductivity and modified PP material with high thermal conductivity are used along the vertical direction of the plate surface to achieve a significant difference in thermal conductivity between the two sides of the plate surface. The thermal conductivity of one side of the hollow plastic template is very low, generally 0.13 W / (m·K); the thermal conductivity of the other side is relatively high, which can reach 1.5 W / (m·K) to 2.0 W / (m·K). The side with high thermal conductivity is in direct contact with the concrete, and its thermal conductivity is comparable to that of the concrete, which can effectively exchange heat with the concrete body, and then the heat medium in the internal channel of the hollow plastic template can quickly and accurately regulate and control the concrete curing temperature; the thermal conductivity of the other side of the hollow plastic template is very low, which greatly reduces the heat exchange efficiency between the heat medium, the concrete and the outside, has good heat preservation effect, realizes the effective utilization of the hydration heat of the concrete, and has low heat loss and energy saving effect.

[0039] A sealing separation rib is arranged between the two adjacent longitudinal flow channels 10. By staggered arrangement of the transverse communication grooves 13 at both ends of the plate, the both ends of the hollow plastic template are welded and closed by a solid edge strip to obtain an "S"-shaped closed heat medium circulation channel inside the template. The medium outlet 17 and the medium inlet 16 are arranged vertically to the plate surface on the heat preservation side of the hollow plastic template, and are respectively communicated with the first end and the last end of the "S"-shaped closed heat medium circulation channel inside the hollow template, so that the medium outlet 17, the medium inlet 16 and the heat medium circulation channel can form a closed heat medium circulation path.

[0040] The transverse communication grooves 13 are arranged at both ends of the plate body 1, and are used to communicate two or more adjacent longitudinal flow channels 10 on both sides of the sealing separation rib. The depth of the transverse communication groove can be designed according to the equivalent principle of flow area. A sealing separation rib is arranged between the two adjacent transverse communication grooves 13. The transverse communication grooves 13 at both ends of the plate must be staggered arranged, so that the internal channel can form an "S"-shaped heat medium circulation path. The solid edge strip is a solid strip with the same material and thickness as the hollow plastic template. After the transverse communication groove is completed, the both ends of the hollow plastic template can be sealed by hot melt welding technology, so that the both sides of the transverse communication groove and the sealing separation rib can be effectively hot melt welded with the solid edge strip as a whole to achieve effective sealing effect.

[0041] The medium outlet 17 and the medium inlet 16 have a threaded structure, which can be connected with the pipeline of the external circulating heating system through threads. The medium outlet 17 and the medium inlet 16 are communicated with the start and end points of the "S"-shaped closed heat medium circulation channel.

[0042] Compared with the related art, the heating and heat preservation template in the application comprises a plate body, a first edge sealing batten and a second edge sealing batten, the first edge sealing batten and the second edge sealing batten extend in the horizontal axis direction, one side surface of the plate body is provided with a medium outlet and a medium inlet, the medium inlet and the medium outlet are both provided with a valve, a heat medium circulation channel is arranged in the plate body, the heat medium circulation channel is used for circulating flow of heat medium, two ends of the heat medium circulation channel are respectively communicated with the medium inlet and the medium outlet, and two side edges of the plate body are respectively provided with openings; the first edge sealing batten and the second edge sealing batten respectively seal the openings of the two side edges of the plate body. The heating and heat preservation template is attached to the object to be heat preserved, and the temperature control energy efficiency of the object to be heat preserved can be improved.

[0043] The heating and heat preservation template with the heating and heat preservation function in the application not only has the supporting and forming function of the traditional concrete template, but also has the concrete curing temperature regulation function, changes the technical status that the existing template structure and the heating device are relatively independent, and proposes a new template system solution of concrete curing with a template in an integrated and highly fused technical solution.

[0044] The heating and heat preservation template with the heating and heat preservation function in the application has the characteristic that the heat conduction performance of the vertical surface has a significant difference, can not only realize effective heat exchange between the heat medium and the concrete body, accurately regulate the concrete curing temperature index, but also has the heat preservation function. The integrated technology of heat conduction and heat preservation has the effects of high heat conduction efficiency, low heat energy dissipation, energy saving and consumption reduction.

[0045] The heating and heat preservation template with the heating and heat preservation function in the application builds a closed heat medium passage in the template plate body through a special hollow cross-section structure and a plate end construction processing method. The passage can be uniformly distributed in the template body, so that the concrete is uniformly heated, the temperature stress caused by temperature difference is avoided to cause the concrete to crack, and the concrete engineering quality is ensured.

[0046] The manufacturing method of the heating and heat preservation template with the heating and heat preservation function in the application has the effects of simplicity, small implementation difficulty and low cost.
