Abstract
Description
Technical Field
[0001] This application belongs to the field of building exterior wall repair technology, specifically relating to mosaic exterior wall repair structures. Background Technology
[0002] Mosaic exterior walls typically refer to building exteriors constructed using small mosaic tiles, a common feature in various types of buildings. Over time, mosaic exterior walls can experience issues such as tile detachment, cracks, hollow areas, and water seepage, requiring renovation and repair. Current repair methods often involve completely removing the entire mosaic facade and then relaiding with new tiles, or applying a waterproof coating.
[0003] However, the process of removing old tiles requires manual, piece-by-piece mechanical breaking, which can easily damage the base structure of the wall, especially affecting the stability of the walls in older buildings. Furthermore, when laying new tiles or applying new waterproofing coatings, the poor compatibility between the old and new adhesives, or between the new waterproofing coating and the old adhesive, can easily lead to the peeling of the new exterior wall material, making it difficult to meet durability requirements. Utility Model Content
[0004] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a mosaic exterior wall repair structure that can prevent the wall base from being damaged during construction, enhance the adhesion of waterproof coating, achieve double waterproof protection for the old exterior wall, and ensure the durability of the new wall surface.
[0005] To achieve the above objectives, this application provides a mosaic exterior wall repair structure, the mosaic exterior wall repair structure comprising:
[0006] The wall base layer includes a mortar base layer and a mosaic tile layer covering the mortar base layer;
[0007] A polymer mortar layer, wherein the polymer mortar layer covers the mosaic tile layer and fills the tile gaps of the mosaic tile layer; and
[0008] A waterproof coating layer is applied over the polymer adhesive layer to form a continuous, sealed waterproof membrane.
[0009] In some embodiments, the polymer adhesive layer also fills the base layer gap between the mortar base layer and the mosaic tile layer.
[0010] In some embodiments, the mosaic tile layer includes a hollow removal area, and the mosaic exterior wall repair structure includes a mortar reinforcement layer filled in the hollow removal area.
[0011] In some embodiments, the mortar reinforcement layer includes a hot-dip galvanized steel wire mesh layer embedded in the mortar filler.
[0012] In some embodiments, the mosaic exterior wall repair structure further includes an alkali-resistant primer layer disposed beneath the mortar reinforcement layer.
[0013] In some embodiments, the edges of the polymer mortar layer and the waterproof coating layer extend to cover key wall nodes, including window sills, eaves, pipe penetrations, or balcony connections.
[0014] In some embodiments, the thickness of the polymer adhesive layer is at least 3 mm.
[0015] In some embodiments, the waterproof coating layer is a polymer cement waterproof coating layer or an acrylic waterproof coating layer.
[0016] In some embodiments, the thickness of the waterproof coating layer is at least 1.5 mm.
[0017] In some embodiments, the mosaic exterior wall repair structure further includes a putty layer and a decorative coating layer, wherein the putty layer covers the waterproof coating layer and the decorative coating layer covers the putty layer.
[0018] Through the above technical solution, the mosaic exterior wall repair structure of this application can preserve the original mosaic tile layer, avoiding damage to the mortar base or masonry (such as expansion of hollow areas or structural loosening) caused by removal, maintaining the stability of the building wall and protecting the decorative, thermal insulation, and waterproofing effects. Applying polymer mortar to the original mosaic tile layer serves two purposes: firstly, the polymer mortar can penetrate into the tile gaps, repairing them and effectively protecting the original mosaic tile layer; secondly, the polymer mortar layer acts as an intermediate layer, exhibiting strong compatibility with the subsequently applied waterproof coating, resulting in high adhesion of the waterproof coating layer covering the polymer mortar layer, reducing the risk of cracking and peeling, and improving the durability of the renovated exterior wall. Simultaneously, the polymer mortar layer and the waterproof coating layer work together to form double protection, ensuring the waterproofing effect of the mosaic exterior wall.
[0019] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

[0026] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.
[0027] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.
[0028] like Figure 1 As shown in the exemplary embodiment of this application, a mosaic exterior wall repair structure is provided, which mainly includes a wall base layer 1, a polymer mortar layer 2, and a waterproof coating layer 3. The wall base layer 1 includes the original mortar base layer and the original mosaic tile layer, with the mosaic tile layer serving as the exterior wall surface to be repaired, covering the mortar base layer. The polymer mortar layer 2 covers the mosaic tile layer, and during application, the fluid polymer mortar can penetrate into the tile gaps of the mosaic tile layer, filling the gaps after solidification. Optionally, the thickness of the polymer mortar layer 2 is at least 3 mm, thereby providing sufficient bonding strength and impermeability. The waterproof coating layer 3 covers the polymer mortar layer 2, thereby forming a continuous and sealed waterproof membrane on the exterior wall surface.
[0029] Optionally, the waterproof coating layer 3 is a polymer cement waterproof coating layer 3 or an acrylic waterproof coating layer 3. By utilizing the material flexibility and bonding properties of polymer cement or acrylic, the waterproof coating layer 3 can adapt to the micro-deformation of the substrate and has compatibility with the polymer adhesive mortar, thus forming a synergistic waterproofing effect.
[0030] Optionally, the thickness of the waterproof coating layer 3 is at least 1.5 mm, thereby preventing the waterproof coating from dripping during construction and ensuring that the formed waterproof membrane is continuous and intact.
[0031] Therefore, when using the mosaic exterior wall repair structure of this exemplary embodiment, it is not necessary to remove the original mosaic tile layer, avoiding mechanical breakage that could damage the mortar base and deeper masonry. This maintains the protective function of the original mosaic tile layer on the mortar base, while preserving the decorative, insulation, and waterproofing effects. The polymer mortar layer 2, covering the mosaic tile layer, can repair tile gaps and level damaged areas, ensuring a smooth and aesthetically pleasing exterior wall surface. Simultaneously, the polymer mortar layer 2 can serve as an intermediate layer, compatible with the waterproof coating layer 3, allowing the waterproof coating layer 3 to adhere firmly to the polymer mortar layer 2, preventing premature cracking and peeling, and improving the durability of the renovated exterior wall.
[0032] Overall, the layered polymer adhesive mortar layer 2 and waterproof coating layer 3 provide dual protection for the mosaic tile layer, thereby significantly improving the waterproofing effect of the renovated exterior wall. In addition, compared to existing mosaic exterior wall repair solutions, the repair structure solution in this embodiment also has the following advantages:
[0033] In terms of construction efficiency, existing exterior wall repair solutions require the complete removal of mosaic tiles and multiple processes such as cleaning, repair, and coating. The removal process alone accounts for 40%-60% of the total construction period and is greatly affected by weather and building height, resulting in extremely low construction efficiency. However, this new mosaic exterior wall repair structure eliminates the need for removal and base layer repair. It directly cleans the mosaic tile surface, repairs gaps, and applies a layer of adhesive mortar and waterproof coating, shortening the construction period by 50%-70%, making it particularly suitable for large-scale renovation projects.
[0034] Regarding construction costs, the cost of removing mosaic tiles (labor, machinery, and waste removal) in existing exterior wall repair solutions accounts for 30%-40% of the total cost, and additional repair costs may be incurred due to damage to the base layer. The repair solution of this invention can reduce the cost of demolishing and handling exterior walls, and also eliminates the repair costs resulting from damage to the exterior wall insulation and decorative layers. Therefore, the overall cost of this invention can be reduced by 20%-30%.
[0035] In terms of environmental protection, existing exterior wall repair solutions generate a large amount of construction waste (tiles, mortar fragments, etc.) by removing the exterior walls, which easily causes dust pollution during transportation and disposal, and generates a lot of noise during construction. In contrast, the repair solution of this utility model eliminates the demolition process, reduces construction waste emissions by more than 90%, and avoids the impact of noise pollution on surrounding residents, thus meeting the requirements of low-carbon construction.
[0036] Regarding construction safety, existing exterior wall repair solutions pose a risk of material falling and injuring people during high-altitude exterior wall removal operations, especially when the adhesion of old tiles has decreased, making them prone to detachment in whole pieces. This new repair solution only requires cleaning and coating the surface of the mosaic tiles, reducing high-altitude machinery operations and lowering the probability of accidents.
[0037] For the exterior walls of historical buildings and distinctive decorations, the restoration solution of this utility model can preserve the original decorative effect of the mosaic tiles, meet the requirements of cultural relic protection or style coordination, and avoid destructive renovation.
[0038] In later maintenance work, the mosaic exterior wall repair structure of this utility model does not require large-scale demolition and repair. Only local repairs need to be made directly on the coating surface, thereby reducing the later maintenance cost.
[0039] Utilizing the high permeability of polymer adhesive mortar, polymer adhesive mortar layer 2 can not only fill the micropores and gaps of the tiles, but also fill the gaps between the mortar base layer and the mosaic tile layer. Polymer adhesive mortar layer 2 is also bonded to the bottom surface of the mosaic tile and the top surface of the mortar base layer, forming chemical bonds and mechanical interlocking, thereby enhancing the interfacial adhesion.
[0040] If the existing mosaic tile layer exhibits hollowness, cracking, or loosening, it is necessary to locally remove the hollow areas, creating a hollow removal zone. Therefore, to repair this hollow removal zone, in one embodiment, the mosaic exterior wall repair structure also includes a mortar reinforcement layer. This mortar reinforcement layer fills the hollow removal zone, making it flush with the mosaic tile layer to avoid contact with the applied polymer mortar layer 2. Alternatively, in other embodiments, the applied polymer mortar layer 2 can be directly used to fill the hollow removal zone, restoring the mosaic tile layer to a smooth surface.
[0041] Furthermore, the mortar reinforcement layer includes a hot-dip galvanized steel wire mesh layer embedded in the mortar filler. The hot-dip galvanized steel wire mesh layer disperses stress, preventing secondary cracking in the repair area due to base deformation or shrinkage, thus improving the stability of the repair structure. At the same time, the hot-dip galvanized steel wire mesh has good rust prevention effect, improving the durability of the mortar reinforcement layer.
[0042] In addition, the mosaic exterior wall repair structure may also include an alkali-resistant primer layer placed under the mortar reinforcement layer. The alkali-resistant primer layer can inhibit the erosion of the mortar reinforcement layer by alkaline substances precipitated from the mortar base layer, thus extending the durability of the repair layer.
[0043] In actual construction, the first step is to apply an alkali-resistant primer to the area where the hollow tiles have been removed. In other words, apply an alkali-resistant primer layer to the mortar base layer exposed by the mosaic tile layer. Then, fill in the crack-resistant mortar, then hang a layer of hot-dip galvanized steel wire mesh. Finally, cover the hot-dip galvanized steel wire mesh with crack-resistant mortar and level it to complete the mortar reinforcement layer construction. The thickness of the crack-resistant mortar and the width of the hot-dip galvanized steel wire mesh can be set according to the actual size of the hollow tile area. For example, a 3mm thick layer of crack-resistant mortar can be filled, and a 300mm wide hot-dip galvanized steel wire mesh can be used for construction.
[0044] Furthermore, in some buildings, mosaic tiles are not only used on the exterior walls, but also on key wall joints, such as window sills, eaves, pipe penetrations, and balcony connections. These key wall joints are relatively weak and prone to leakage. Removing the existing mosaic tiles from these joints can easily damage them. Therefore, in one embodiment, the edges of the polymer mortar layer 2 and the waterproof coating layer 3 extend to cover the key wall joints, completely covering them. This provides focused protection for high-risk leakage points, creating a continuous waterproof seal and improving the overall reliability of the waterproofing system.
[0045] In one embodiment, reference is made to... Figure 1 The mosaic exterior wall repair structure also includes a putty layer 4 and a decorative paint layer 5. The putty layer 4 covers the waterproof paint layer 3, and the decorative paint layer 5 covers the putty layer 4. In this embodiment, the putty layer 4 can be applied in two coats, followed by a coat of primer. The decorative paint layer 5 can be selected from different colors of exterior wall paint according to actual design requirements. A smooth putty layer 4 provides a smooth base surface for the decorative paint layer 5, which is beneficial for beautifying the exterior wall appearance. Simultaneously, the decorative paint layer 5 enhances the mosaic exterior wall's protection against the external environment.
