Technical Field
[0001] The utility model relates to the field of passive house building products, in particular to a splicing structure of exterior wall decorative panels for passive houses. Background Technique
[0002] A passive house is an integrated product of various technical products, and is a house in which the total sum of all consumed primary energy does not exceed 120 kWh / (square meter·year) by making full use of renewable energy. Such a low energy consumption standard is achieved through a building exterior wall with high heat insulation and sound insulation, strong airtightness, and renewable energy.
[0003] The existing heat preservation function of passive houses is mainly achieved by arranging a heat preservation layer between the light steel keel and the exterior wall panel. However, since the heat preservation layer products are spliced together in multiple pieces, splicing seams are likely to appear at the intersection positions of two products. The positions of traditional splicing seams are directly bonded with sealant, thus reducing the overall airtightness of the passive house.
[0004] In order to solve the above existing problems, the utility model provides a splicing structure of exterior wall decorative panels for passive houses. Content of the Utility Model

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0024] Embodiment 1:
[0025] See also Figure 1-2As shown in the figure, the splicing structure of the exterior wall decorative panel of the passive house of the present utility model includes a light steel keel 1 installed on the inner side and an exterior wall panel 3 installed on the outer side. A thermal insulation layer 2 is provided between the light steel keel 1 and the exterior wall panel 3. The light steel keel 1, the exterior wall panel 3 and the thermal insulation layer 2 are assembled into one body. Specifically, between the light steel keel 1, the thermal insulation layer 2 and the exterior wall panel 3, they are locked from the outside to the inside by high-strength plastic anchor bolts 4 to achieve assembly.
[0026] Due to the different lengths of the wall, the thermal insulation layer 2 is composed of several thermal insulation boards of different sizes spliced together. There is a splicing seam 5 between each adjacent thermal insulation board. The splicing seam 5 is arranged perpendicular to both the light steel keel 1 and the exterior wall panel 3 at the same time. On the side of the splicing seam 5 facing the exterior wall panel 3, a breathable film 6 is laid. The breathable film 6 is clamped between the thermal insulation layer 2 and the exterior wall panel 3; after assembly, the splicing seam 5 is filled with sealant.
[0027] In the first embodiment, the breathable film 6 is clamped in the exterior wall panel 3 in a "冂" shape. Therefore, when designing and installing, the problem of embedding needs to be considered. The exterior wall panel 3 is set to include a side large board and a small buckle plate 7. The breathable film 6 is wrapped by the way of clamping the side large board and the small buckle plate 7. The short side of the breathable film 6 is clamped between the side large board and the small buckle plate 7, and the long side of the breathable film 6 is pressed between the thermal insulation layer 2 and the exterior wall panel 3.
[0028] At the same time, in order to better achieve airtightness, the long side direction of the breathable film 6 is perpendicular to the setting direction of the splicing seam 5, so as to disperse the gas infiltrated into the sealant, enhance the overall airtightness of the passive house, and when the long side of the breathable film is longer, that is, the channel for gas to extend in is also longer, the airtightness is better, and at the same time, the effect of preventing the internal gas from escaping is enhanced. When installing, the breathable film 6 is often evenly distributed on both sides of the splicing seam 5.
[0029] Embodiment 2:
[0030] The splicing structure of the exterior wall decorative panel of the passive house of the present utility model includes a light steel keel 1 installed on the inner side and an exterior wall panel 3 installed on the outer side. A thermal insulation layer 2 is provided between the light steel keel 1 and the exterior wall panel 3. The light steel keel 1, the exterior wall panel 3 and the thermal insulation layer 2 are assembled into one body. Specifically, between the light steel keel 1, the thermal insulation layer 2 and the exterior wall panel 3, they are locked from the outside to the inside by high-strength plastic anchor bolts 4 to achieve assembly.
[0031] Due to the different lengths of the wall, the thermal insulation layer 2 is composed of several thermal insulation boards of different sizes spliced together. There is a splicing seam 5 between each adjacent thermal insulation board. The splicing seam 5 is arranged perpendicular to both the light steel keel 1 and the exterior wall panel 3 at the same time. On the side of the splicing seam 5 facing the exterior wall panel 3, a breathable film 6 is laid. The breathable film 6 is clamped between the thermal insulation layer 2 and the exterior wall panel 3; after assembly, the splicing seam 5 is filled with sealant.
[0032] In the second embodiment, the breathable membrane 6 is sandwiched between the thermal insulation layer 2 and the exterior wall panel 3 in an "I" shape. Therefore, there is no need to consider the embedding problem during design and installation as in the first embodiment. Therefore, there is no special requirement for the exterior wall panel 3. It should be noted that the setting direction of the breathable membrane 6 is perpendicular to the setting direction of the joint seam 5. The setting principle is the same as that in the first embodiment. By extending the gas entry channel, the gas entry is blocked or weakened, and the effect of preventing internal gas from escaping is also enhanced, thereby enhancing the air tightness. The longer the breathable membrane is, that is, the longer the channel for the gas to extend, the better the air tightness. During installation, the breathable membrane 6 is often evenly distributed on both sides of the joint seam 5.
[0033] It should be noted that if not listed in the embodiments, the method of extending the gas channel through the breathable membrane 6 or a membrane of equivalent nature also belongs to the protection scope of this solution. For example, the breathable membrane 6 is set to an "L" shape to achieve the same effect, which is also an extension of the idea to be protected by this solution.
[0034] The above embodiments are preferred implementation modes of the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the implementation modes of the present utility model are not limited to the above embodiments. For those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
