Description

Technical Field

[0001] This utility model relates to the field of wall repair technology, and in particular to the repair structure of the inner side of the wall in old residential communities. Background Technology

[0002] In the process of optimizing energy conservation in historical buildings, the special characteristics of historical buildings should be fully considered, and targeted measures should be proposed in combination with the current status of the buildings. In order to give full play to the historical value of the buildings, on the one hand, appropriate protection and repair measures need to be taken to restore the building functions, improve the building's thermal performance, and improve the building's insulation performance. On the other hand, the principle of protecting historical buildings should also be observed, and the historical features of the buildings should not be damaged.

[0003] In summary, while the traditional method of internal wall insulation in older residential communities is feasible, the most significant problem with internal insulation systems is the potential for thermal bridging. Thermal bridging occurs when the building envelope exchanges heat with the outside environment; some parts of the envelope have a much higher heat transfer coefficient than others, resulting in a larger heat exchange volume and impacting building energy consumption and heating / cooling loads. Therefore, it is particularly necessary to repair the internal wall structure in older residential communities. Utility Model Content

[0004] The purpose of this utility model is to provide a repair structure for the inner side of the walls of old residential communities, in order to solve the problem mentioned in the background art that the traditional method of using the inner side of the walls for insulation in old residential communities is feasible, but the most obvious problem with the use of the internal insulation system is that it may generate "thermal bridges". "Thermal bridges" refer to the phenomenon that when the building envelope exchanges heat with the outside world, the heat transfer coefficient of some parts of the envelope is much greater than that of other parts, resulting in a large amount of heat exchange and affecting the building's energy consumption and heating and cooling loads.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an inner wall repair structure for old residential communities, including an outer wall, an inner wall installed on the side of the outer wall, and a repair structure provided at the corner of the inner wall and the outer wall;

[0006] The repair structure includes an insulating mortar layer, an inner insulating layer, polystyrene foam particles, adhesive powder, an adhesive layer, an insulating layer, a protective layer, a finishing layer, and cement. The insulating mortar layer is bonded to the side surface of the inner wall. The insulating mortar layer is filled with polystyrene foam particles, adhesive powder, and cement. The adhesive layer is bonded to the side surface of the outer wall. The insulating layer is bonded to the side surface of the adhesive layer. The insulating layer is bonded to the side surface of the insulating layer. The insulating layer is bonded to the side surface of the insulating layer.

[0007] Preferably, the adhesive powder material is filled inside the thermal insulation mortar layer, and there are multiple adhesive powder materials.

[0008] Preferably, the cement material is filled inside the thermal insulation mortar layer, and there are multiple cement materials.

[0009] Preferably, a protective layer is attached to the side surface of the insulation layer, and the protective layer is connected between the insulation layer and the adhesive layer.

[0010] Preferably, the polystyrene foam particles are filled inside the thermal insulation mortar layer, and the number of polystyrene foam particles is multiple.

[0011] Preferably, an inner insulation layer is attached to the side surface of the thermal insulation mortar layer, and the inner insulation layer is connected to the outer wall through the thermal insulation mortar layer.

[0012] Preferably, a finishing layer is attached to the side surface of the protective layer, and the finishing layer is connected between the protective layer and the insulation layer.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: Because the wall absorbs some heat during heating in an external insulation system, rooms with internal insulation require less time to reach the same target temperature. Internal wall insulation involves attaching the insulation material to the inner side of the wall, which does not affect the exterior facade, maintaining the original appearance of the building and helping to showcase its original features, protecting the characteristics of the neighborhood and city. Internal insulation construction does not require working at heights, the construction process is simple and easy to operate, and each room can be worked on individually with flexible methods, saving manpower and equipment costs. Furthermore, less insulation material is used for the same building area compared to external insulation, saving material costs. Typically, thermal bridging easily occurs between the exterior and interior walls. At the junctions of structural components and room corners, the heat loss due to thermal bridges can be reduced by increasing the thickness of the insulation layer or extending it to the inner wall. Applying a layer of insulating mortar to the thermal bridge area can also reduce heat loss. The insulating mortar layer is made of polystyrene foam particles, adhesive powder, and cement. This material has a low thermal conductivity and good insulation performance, and is not prone to cracking. Because it is applied on-site, it has good overall integrity and is suitable for insulation designs at corners and irregularly shaped walls. Applying the insulating mortar layer along the inner wall direction can reduce the impact of thermal bridges on the overall insulation performance of the outer wall, and it is also inexpensive. A vapor barrier layer can also be applied to the outside of the insulating mortar layer to prevent internal condensation and protect the insulating mortar layer.

[0014] The thermal insulation performance of a wall is positively correlated with the thickness of the thermal insulation mortar layer. As the thickness of the thermal insulation mortar layer increases, the thermal insulation performance of the wall is better, and the heat loss at thermal bridges gradually decreases, but the reduction rate also decreases. The thickness of the thermal insulation mortar layer ranges from 20mm to 50mm. Considering that the thickness of the interior wall thermal insulation mortar layer has a significant impact on the usable space and aesthetics of the interior, the preferred thickness of the thermal insulation mortar layer is 20mm, taking into account both economy and practicality. Compared with an exterior wall structure without an interior wall thermal insulation mortar layer, applying a thermal insulation mortar layer can reduce heat loss at thermal bridges. Adding a thermal insulation mortar layer at thermal bridges can reduce heat loss. The worse the overall thermal insulation performance of the exterior wall, the more obvious the effect of adding thermal bridge insulation measures. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an inner wall repair structure for old residential communities, including an outer wall 1, an inner wall 2 installed on the side of the outer wall 1, and a repair structure 3 at the corner of the inner wall 2 and the outer wall 1.

[0022] The repair structure 3 includes an insulating mortar layer 301, an inner insulation layer 302, polystyrene foam particles 303, adhesive powder 304, an adhesive layer 305, an insulation layer 306, a protective layer 307, a finishing layer 308, and cement material 309. The insulating mortar layer 301 is bonded to the side surface of the inner wall 2. The interior of the insulating mortar layer 301 is filled with polystyrene foam particles 303, adhesive powder 304, and cement material 309. The adhesive layer 305 is bonded to the side surface of the outer wall 1. The side surface of insulation layer 305 is bonded to insulation layer 306, and the side surface of insulation layer 306 is bonded to insulation layer 306. Because the wall absorbs some heat when the external insulation system is heating, rooms with internal insulation require less time to reach the same target temperature. Internal wall insulation involves attaching the insulation material to the inside of the wall, which does not affect the exterior facade, maintaining the original appearance of the building and helping to showcase its original character, protecting the neighborhood and urban features. Internal insulation construction does not require working at heights, the construction process is simple and easy to operate, and each room can be worked on individually with flexible methods, saving manpower. Compared to equipment costs, thermal bridges require less insulation material for the same building area than external insulation methods, thus saving material costs. Typically, thermal bridges occur at the junction of the exterior wall 1 and the internal structure, as well as at room corners. Heat loss from thermal bridges can be reduced by increasing the thickness of the insulation layer or extending it to the interior wall 2, and by applying an insulating mortar layer 301 to the thermal bridge area. The insulating mortar layer 301 is made of a mixture of polystyrene foam particles 303, adhesive powder 304, and cement 309. This material has a low thermal conductivity and good insulation performance, and is not prone to cracking. Because the plastering is done on-site during construction, therefore... With good overall integrity, it is suitable for insulation design at corners and irregularly shaped walls. Applying the insulation mortar layer 301 along the inner wall 2 direction can reduce the impact of thermal bridges on the overall insulation performance of the outer wall 1, and it is also inexpensive. A vapor barrier layer can also be applied to the outside of the insulation mortar layer 301 to prevent internal condensation and protect the insulation mortar layer 301. The wall insulation performance is positively correlated with the thickness of the insulation mortar layer 301. As the thickness of the insulation mortar layer 301 increases, the wall insulation performance is better, and the heat loss at the thermal bridge site gradually decreases, but the reduction rate also decreases. The thickness range of the insulation mortar layer 301 is 20mm- Considering that the thickness of the thermal insulation mortar layer 301 on the inner wall 2 has a significant impact on the indoor usable space and aesthetics, the thickness of the thermal insulation mortar layer 301 is preferably 20mm, taking into account both economy and practicality. Compared with the structure of the outer wall 1 without the thermal insulation mortar layer 301 applied along the inner wall 2, applying the thermal insulation mortar layer 301 can reduce the heat loss at the thermal bridge. Adding the thermal insulation mortar layer 301 at the thermal bridge can reduce heat loss. The worse the overall thermal insulation performance of the outer wall 1, the more obvious the effect of adding thermal bridge insulation measures.

[0023] Furthermore, the adhesive powder material 304 is filled inside the thermal insulation mortar layer 301, and there are multiple adhesive powder materials 304. The multiple adhesive powder materials 304 make it convenient for users to use the thermal insulation mortar layer 301 for thermal insulation.

[0024] Furthermore, cement material 309 is filled inside the thermal insulation mortar layer 301, and there are multiple cement materials 309. The multiple cement materials 309 make it easier for users to enhance the thermal insulation of the thermal insulation mortar layer 301.

[0025] Furthermore, a protective layer 307 is attached to the side surface of the insulation layer 306, and the protective layer 307 is connected between the insulation layer 306 and the adhesive layer 305. The protective layer 307, which connects the insulation layer 306 and the adhesive layer 305, makes it easy for users to connect the insulation layer 306 and the protective layer 307.

[0026] Furthermore, polystyrene foam particles 303 are filled inside the thermal insulation mortar layer 301, and there are multiple polystyrene foam particles 303. The multiple polystyrene foam particles 303 make it convenient for users to perform secondary reinforcement of the thermal insulation mortar.

[0027] Furthermore, an inner insulation layer 302 is attached to the side surface of the thermal insulation mortar layer 301, and the inner insulation layer 302 is connected to the outer wall 1 through the thermal insulation mortar layer 301. The inner insulation layer 302 connected to the outer wall 1 through the thermal insulation mortar layer 301 makes it easy for users to connect the inner insulation layer 302 to the outer wall 1.

[0028] Furthermore, a decorative layer 308 is attached to the side surface of the protective layer 307, and the decorative layer 308 is connected between the protective layer 307 and the insulation layer 306. The decorative layer 308, which is connected between the protective layer 307 and the insulation layer 306, makes it easy for users to connect the decorative layer 308 and the insulation layer 306.

[0029] Working principle: Because the walls absorb some heat when the external insulation system is used for heating, rooms with internal insulation require less time to reach the same target temperature. Internal wall insulation involves attaching the insulation material to the inside of the wall, which does not affect the exterior facade, maintaining the original appearance of the building and helping to showcase its original features, protecting the characteristics of the neighborhood and city. Internal insulation construction does not require working at heights, the construction process is simple and easy to operate, and each room can be worked on individually with flexible methods, saving labor and equipment costs. Furthermore, less insulation material is used for the same building area with external insulation, saving material costs. Typically, thermal bridges tend to appear at the junction of the exterior wall and the internal structure, as well as at room corners. These can be addressed by increasing... The thickness of the insulation layer or the extension of the insulation layer to the inner wall 2, and the measures of applying the insulation mortar layer 301 to the thermal bridge part reduce the heat loss of the thermal bridge. The insulation mortar layer 301 is made of polystyrene foam particles 303, adhesive powder 304 and cement 309. This material has a low thermal conductivity and good insulation performance, and is not easy to crack. Because it is plastered on site during construction, it has good integrity and is suitable for insulation design at corners and irregular walls. Applying the insulation mortar layer 301 along the direction of the inner wall 2 can reduce the impact of thermal bridge on the overall insulation performance of the outer wall 1, and the cost is low. A vapor barrier layer can also be applied to the outside of the insulation mortar layer 301 to prevent internal condensation and protect the insulation mortar layer 301.

[0030] The thermal insulation performance of the wall is positively correlated with the thickness of the thermal insulation mortar layer 301. As the thickness of the thermal insulation mortar layer 301 increases, the thermal insulation performance of the wall is better, and the heat loss at the thermal bridge gradually decreases, but the reduction also decreases. The thickness range of the thermal insulation mortar layer 301 is 20mm-50mm. Considering that the thickness of the thermal insulation mortar layer 301 on the inner wall 2 has a significant impact on the indoor usable space and aesthetics, the thickness of the thermal insulation mortar layer 301 is preferably 20mm, taking into account both economy and practicality. Compared with the structure of the outer wall 1 without the thermal insulation mortar layer 301 applied along the inner wall 2, applying the thermal insulation mortar layer 301 can reduce the heat loss at the thermal bridge. The thermal insulation measures of adding the thermal insulation mortar layer 301 at the thermal bridge can reduce heat loss. The worse the overall thermal insulation performance of the outer wall 1, the more obvious the effect of adding thermal bridge insulation measures.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
