In severe cases, the structural layer will be damaged by freezing.
[0004] To avoid the above situation, in addition to minimizing the number and area of cold bridges as much as possible, it is also necessary to improve the inevitable envelope structure with cold bridges. Content of the Utility Model

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0030] The present utility model provides a cold-bridge prevention enclosure structure, and this enclosure structure includes an enclosure main body 1 and a heating element 2. For its structure, please refer toFigures 1 - 2 。
[0031] Specifically, the enclosure main body 1 can be a wall for constructing a building. The wall has a certain thickness.
[0032] The enclosure main body 1 has a side wall 11, and mounting holes 12 are formed in at least one side wall 11. An accommodation cavity 13 is provided in the enclosure main body 1, and the mounting holes 12 are used to communicate the accommodation cavity 13 with the external environment of the enclosure main body 1. After the enclosure main body 1 is prepared, other functional components can be installed into the accommodation cavity 13 through the mounting holes 12.
[0033] Please refer to Figure 2 , in this embodiment, the heating element 2 can pass through the mounting hole 12 and be disposed in the accommodation cavity 13 located inside the enclosure main body 1 to heat the enclosure main body 1, so that the temperature of the side of the enclosure main body 1 close to the interior is increased, thereby reducing the possibility of condensate generation in the room and avoiding damage to the enclosure structure.
[0034] In the technical solution provided by the present utility model, by filling the heating element 2 in the enclosure main body 1, problems such as condensation, frosting, and icing caused by low temperature in the cold bridge part that cannot form a continuous thermal insulation structure can be avoided, and the enclosure structure can be prevented from being damaged due to the existence of the cold bridge.
[0035] At least a part of the above-mentioned enclosure main body 1 is used to connect the roof 10 and / or the drain gutter 20.
[0036] Please refer to Figure 3 , the enclosure structure connects the roof 10 and the drain gutter 20. Since the thermal insulation layer of the roof 10 is arranged on the outside, and the drain gutter 20 part is usually provided with a waterproof layer instead of a thermal insulation layer, a cold bridge is extremely likely to be formed at the joint of the roof 10, the drain gutter 20 and the enclosure main body 1, and thus condensate is likely to be formed on the surface of the side of the enclosure main body 1 close to the interior.
[0037] In order to enable the heat generated by the heating element 2 to be conducted to the side of the enclosure main body 1 inside the room more evenly and effectively, in addition to adjusting the heating power, quantity and arrangement density of the heating element 2, in some embodiments, a heat conducting element 3 can be provided in the enclosure main body 1.
[0038] The above-mentioned heat conducting element 3 is used to conduct the heat generated by the heating element 2 to different regions of the enclosure main body 1, especially to transfer the heat emitted by the heating element 2 more evenly to the surface of the enclosure structure close to the interior.
[0039] When arranging the heat conducting element 3 and the heating element 2 in the enclosure structure, it can be considered that the heat conducting element 3 and the heating element 2 are arranged in sequence and in contact along the thickness direction of the enclosure structure, and it is preferably considered that the heat conducting element 3 is arranged on the side of the heating element 2 facing the interior.
[0040] In some embodiments, for the convenience of installing the heating element 2 into the enclosure structure, the installation hole 12 communicating with the accommodation cavity 13 may be provided on the side wall 11 of the enclosure structure facing the indoor or outdoor side according to the considerations of installation and later maintenance.
[0041] Alternatively, the above installation hole 12 may also be provided on a certain side wall 11 of the enclosure structure in the thickness direction.
[0042] In some embodiments, the above-mentioned enclosure main body 1 may be formed by pouring concrete.
[0043] In order to further improve the strength of the enclosure main body 1 and at the same time facilitate the preparation of the above-mentioned accommodation cavity 13 and the heat conducting member 3, in some embodiments, a steel bar grid may be provided inside the enclosure main body 1.
[0044] When using the reinforced concrete layer formed by the steel bar grid and concrete pouring as the enclosure main body 1, the strength of the enclosure main body 1 can be improved to a certain extent. In addition, the above-mentioned steel bar grid can also be used as the installation carrier for the heat conducting member 3 and the heating element 2, reducing the installation difficulty of the heat conducting member 3 and the heating element 2, and at the same time enabling the heat conducting member 3 and the heating element 2 to be conveniently and quickly installed at the designated positions according to the design requirements.
[0045] Specifically, the above-mentioned heat conducting member 3 is fixedly arranged on the steel bar grid.
[0046] Please refer to Figure 2 , the above-mentioned heat conducting member 3 is a heat dissipation mesh. During the construction process of the steel bar grid or after the construction is completed, the heat dissipation mesh used to achieve the heat conduction function can be bundled on the steel bar grid.
[0047] In this embodiment or other similar embodiments, a degradable tube may also be bundled on the above-mentioned steel bar grid and / or heat dissipation mesh. The degradable tube is arranged on the heat dissipation mesh and is used to form the accommodation cavity 13 and the installation hole 12.
[0048] The above-mentioned degradable tube can naturally degrade after the concrete poured outside the steel bar mesh has solidified for a certain period of time, so as to form the above-mentioned accommodation cavity 13 and installation hole 12 for installing the heating element 2.
[0049] The structures of the above-mentioned degradable tube, accommodation cavity 13 and installation hole 12 can refer to the structure and formation method of the cavity in the already published patent CN114737755A.
[0050] The number of the mounting holes 12 is affected by the number of the degradable tubes. For example, when the number of the degradable tubes used for preparing the accommodation cavity 13 is one, the number of the mounting holes 12 formed on the side wall 11 of the enclosure body 1 may be one or two; as the number of the degradable tubes increases, the number of the accommodation cavities 13 increases, and the number of the mounting holes 12 also gradually increases.
[0051] In some embodiments, at least part of the accommodation cavity 13 formed by the above-mentioned degradable tubes is a linear cavity extending along a straight line, the number of the linear cavities is multiple, and at least part of the linear cavities are parallel to each other.
[0052] In some embodiments, the heating element 2 is a heat tracing tape.
[0053] The heat tracing tape is an electric heating product used to maintain the temperature of pipelines, equipment or other objects. The heat tracing tape converts electrical energy into heat energy to provide heat for the object to be heat traced, so as to prevent the medium in the object to be heat traced from freezing, solidifying, condensing or maintaining the process temperature.
[0054] When the heat tracing tape is arranged in the enclosure structure, the heat tracing tape can be used to heat the enclosure body 1.
[0055] The heat generated by the heat tracing tape can increase the temperature of the wall surface made of the enclosure body 1. When the temperature of the wall surface is higher than the dew point temperature of the indoor air, the possibility of generating condensate indoors can be reduced, and the possibility of generating condensate on the surface of the enclosure body 1 facing the indoor side can be reduced.
[0056] In order to achieve a better cold bridge prevention effect, in some embodiments, a thermal insulation layer is provided on the outer side of the enclosure body 1.
[0057] The thermal insulation layer can further improve the heat insulation performance of the enclosure body 1.
[0058] The above-mentioned heat tracing tape can provide heat to the enclosure body 1 to make up for the heat loss at the cold bridge part, and the thermal insulation layer plays a role in preventing heat from dissipating outward. The combination of the two can effectively reduce the occurrence of cold bridges in the enclosure structure or increase the temperature of the cold bridge part.
[0059] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all of them should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
