[0054] This application provides a felt-rubber composite layer wall shield. For example... Figure 1-4 As shown, in some embodiments, the felt-rubber composite wall shield includes a heat-insulating and waterproof felt layer 50, a crack-resistant felt layer 60, and a heat-insulating layer 70. The heat-insulating and waterproof felt layer 50 is disposed on the surface of the base wall 10, the crack-resistant felt layer 60 is disposed on the surface of the heat-insulating and waterproof felt layer 50 facing away from the base wall 10, and the heat-insulating layer 70 is disposed on the surface of the crack-resistant felt layer 60 facing away from the surface of the heat-insulating and waterproof felt layer 50. The heat-insulating and waterproof felt layer 50, the crack-resistant felt layer 60, and the heat-insulating layer 70 are arranged sequentially from the inside to the outside.

[0055] The crack-resistant felt layer 60 includes a crack-resistant felt bottom layer 601, which includes a first crack-resistant felt 6011 and a second crack-resistant felt 6012. The edge of the first crack-resistant felt 60111 is provided with a first rough edge 60111, and the edge of the second crack-resistant felt 60122 is provided with a second rough edge 60121. The first rough edge 60111 overlaps with the second rough edge 60121.

[0056] It should be noted that the felt-rubber composite layer wall shield provided in this application embodiment is a protective structure for the exterior wall of the building foundation wall 10. By setting a protective structure layer on the exterior wall of the building foundation wall 10, the exterior wall can play a role in waterproofing, heat insulation and crack prevention.

[0057] Specifically, such as Figure 1 As shown, Figure 1This is a longitudinal cross-sectional view of the crack-resistant felt layer structure in the felt-rubber composite wall shield structure (i.e., a cross-sectional view of the crack-resistant felt layer structure along the thickness direction). A heat-insulating and waterproof felt-rubber layer 50 is provided on the surface of the base wall 10. It should be noted that in this embodiment, the heat-insulating and waterproof felt-rubber layer 50 can be a special felt-rubber, which has both heat insulation and waterproofing functions. By providing a heat-insulating and waterproof felt-rubber layer 50 on the surface of the base wall 10, the composite structure can achieve good heat insulation and waterproofing effects.

[0058] like Figure 1 As shown, the crack-resistant felt layer 60 can be composed of a special crack-resistant felt. By setting the crack-resistant felt layer 60 on the surface of the heat-insulating and waterproof felt layer 50 away from the base wall 10, the stability and crack resistance of the composite layer structure can be improved. In this embodiment, the heat-insulating and waterproof felt layer 50 is composed of a special heat-insulating and waterproof felt.

[0059] like Figure 2-4 As shown, a crack-resistant felt underlayer 601 is provided on the surface of the heat-insulating waterproof felt layer 50 away from the base wall 10. The crack-resistant felt underlayer 601 includes a first crack-resistant felt 6011 and a second crack-resistant felt 6012. The first crack-resistant felt 60111 has a toothed first burr 60111 on its edge. Correspondingly, the second burr 60121 has a toothed second burr 60121 on its edge. The shape of the second burr 60121 is adapted to the shape of the second burr 60121.

[0060] like Figure 3 and 4 As shown, Figure 3 This is a planar schematic diagram showing the overlapping state of the first and second anti-cracking felts in an embodiment of this application. By overlapping the first rough edge 60111 with the second rough edge 60121, that is, by overlapping the outwardly protruding toothed edge of the first rough edge 60111 with the inwardly recessed toothed notch of the second rough edge 60121, a highly flat anti-cracking felt base layer 601 is formed. For example... Figure 4 As shown, since the first rough edge 60111 of the first anti-cracking felt 6011 overlaps the second rough edge 60121 of the second anti-cracking felt 6012 through rough edge overlap, a highly flat anti-cracking felt bottom layer 601 is formed. This can reduce the overlap steps and overlap marks formed by the traditional edge-to-edge overlap method, and can effectively solve the problems of voids or hollows at the overlap in the anti-cracking felt bottom layer 601.

[0061] like Figure 2-4As shown, the first rough edge 60111 of the first crack-resistant felt 60111 overlaps with the second rough edge 60121 of the second crack-resistant felt 6012 to form a highly flat crack-resistant felt base layer 601. This means that the crack-resistant felt base layer 601 formed after the first crack-resistant felt 6011 and the second crack-resistant felt 6012 overlap with the rough edge essentially constitutes a single layer of crack-resistant felt. In practical engineering applications, since the surface area of ​​the wall to be protected varies, it is necessary to overlap crack-resistant felt adhesive layers of different areas to form a whole to cover the wall surface to be protected. The rough edge overlap of the first crack-resistant felt 6011 and the second crack-resistant felt 6012 provided in this embodiment can effectively solve the problem of overlap steps and overlap marks formed by the overlap between traditional crack-resistant felt adhesive layers.

[0062] In this embodiment of the application, the raw filament surfaces of the first crack-resistant felt 6011 and the second crack-resistant felt 6012 are also subjected to heat insulation treatment. At the same time, heat insulation treatment is also performed during the impregnation process of the mesh felt. Such a dual pretreatment process can improve the heat insulation effect of the first crack-resistant felt 6011 and the second crack-resistant felt 6012, and can also improve the toughness of the first crack-resistant felt 6011 and the second crack-resistant felt 6012.

[0063] It should be noted that, Figure 3 This is a schematic diagram showing the burr overlap state of the first and second anti-cracking felts in the embodiments of this application. Figure 3 The gap between the first rough edge 60111 and the second rough edge 60121 is exemplary. When the first anti-cracking felt 6011 and the second anti-cracking felt 6012 are overlapped, a flat overlap surface can be formed between them, and there is no gap between them after the overlap (e.g., ...). Figure 4 As shown, after the first crack-resistant felt 6011 and the second crack-resistant felt 6012 are fully overlapped, the plane of the first crack-resistant felt 6011 and the plane of the second crack-resistant felt 6012 are in the same plane.

[0064] like Figure 1 As shown, the heat insulation layer 70 is disposed on the surface of the crack-resistant felt base layer 601 facing away from the heat-insulating and waterproof felt adhesive layer 50. The heat insulation layer 70 can be composed of an aerogel heat insulation intermediate coating. By disposing of the heat insulation layer 70 on the surface of the crack-resistant felt base layer 601 facing away from the heat-insulating and waterproof felt adhesive layer 50, the heat insulation effect of the composite layer structure can be further improved, and external heat can be blocked outside the base wall 10, thereby improving the heat insulation effect of the base wall 10.

[0065] In this embodiment, the composite thickness of the thermal insulation and waterproof felt layer 50 and the crack-resistant felt layer 60 is set between 0.8 and 1.2 mm. For example, the composite thickness of the thermal insulation and waterproof felt layer 50 and the crack-resistant felt layer 60 can be 0.8 mm, 0.9 mm, 1.0 mm, or 1.2 mm, etc. While ensuring the comprehensive performance of the composite layer structure in terms of thermal insulation and crack resistance, a reasonable design of the composite thickness of the thermal insulation and waterproof felt layer 50 and the crack-resistant felt layer 60 can reduce the construction difficulty and cost of the composite layer structure, and also simplify the overall construction process of the composite layer structure.

[0066] In this embodiment, the thickness of the insulation layer 70 is set between 0.8 and 2.0 mm. For example, the thickness of the insulation layer 70 can be 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, or 2.0 mm, etc. Based on the composite thickness of the heat-insulating waterproof felt adhesive layer 50 and the crack-resistant felt layer 60, the inventors of this application, through reasonable design of the thickness of the insulation layer 70, can further improve the heat insulation effect of the composite layer structure, while also reducing the construction and material costs of the insulation layer 70, and effectively simplifying the overall construction process of the composite layer structure.

[0067] The wall shield of the felt-rubber composite layer provided in this application embodiment is designed with the crack-resistant felt base layer 601 including a first crack-resistant felt 6011 and a second crack-resistant felt 6012, which can be composed of crack-resistant rubber felt. By providing a first rough edge 60111 and a second rough edge 60121 on the edges of the first crack-resistant felt 60111 and the second rough edge 60121 respectively, the overlap between the first rough edge 60111 and the second rough edge 60121 is formed by rough edge overlap to create a crack-resistant base layer 601 with high flatness. This can replace the flush edge overlap method in traditional crack-resistant layers, effectively avoiding the formation of overlap steps and overlap marks, reducing a leveling process and lowering construction costs. At the same time, the rough edge overlap method reduces the existence of overlap marks and improves the flatness and aesthetics of the felt-rubber composite layer.

[0068] like Figure 2-6As shown, in some embodiments, the crack-resistant felt layer 60 further includes a crack-resistant felt surface layer 602. The crack-resistant felt surface layer 602 includes a third crack-resistant felt 6021 and a fourth crack-resistant felt 6022. The edge of the third crack-resistant felt 6021 is provided with a third rough edge 60211, and the edge of the fourth crack-resistant felt 6022 is provided with a fourth rough edge 60221. The third rough edge 60211 overlaps with the fourth rough edge 60221. The crack-resistant felt surface layer 602 is disposed on the surface of the crack-resistant felt bottom layer 601 away from the surface of the heat-insulating and waterproof felt adhesive layer 50, and the overlap of the crack-resistant felt surface layer 602 is laid away from the overlap of the crack-resistant felt bottom layer 601. The heat insulation layer 70 is disposed on the surface of the crack-resistant felt surface layer 602 away from the surface of the heat-insulating and waterproof felt adhesive layer 50; or, the heat insulation layer 70 is disposed on the surface of the crack-resistant felt surface layer 602 away from the surface of the crack-resistant felt bottom layer 601. Because the third rough edge 60211 of the third crack-resistant felt 6021 overlaps with the fourth rough edge 60221 of the fourth crack-resistant felt 6022 through rough edge overlap, thus forming a highly flat crack-resistant felt surface layer 602, the overlap steps and overlap marks formed by the traditional flush edge overlap method can be reduced, effectively solving problems such as voids or blistering at the overlap in the crack-resistant felt surface layer 602. In this embodiment, the crack-resistant felt surface layer 602 can further improve the crack resistance of the overall composite layer structure.

[0069] In this embodiment of the application, the third crack-resistant felt 6021 and the fourth crack-resistant felt 6022 can be composed of crack-resistant rubber felt. For example... Figure 2-6 As shown, by setting a third crack-resistant felt 6021 and a fourth crack-resistant felt 6022 on the surfaces of the first crack-resistant felt 6011 and the second crack-resistant felt 6012 away from the surface of the heat-insulating waterproof felt adhesive layer 50, the stability and crack resistance of the composite layer structure can be further improved. Furthermore, the edge of the third crack-resistant felt 6021 is provided with a toothed third rough edge 60211, and correspondingly, the edge of the fourth crack-resistant felt 6022 is provided with a toothed fourth rough edge 60221. The shapes of the third rough edge 60211 and the fourth rough edge 60221 are matched. By overlapping the third crack-resistant felt 6021 with the fourth crack-resistant felt 6022, that is, by overlapping the toothed rough edge of the outwardly protruding third crack-resistant felt 6021 with the toothed notch of the inwardly recessed fourth crack-resistant felt 6022, a crack-resistant felt surface layer 602 with high flatness can be formed. This can solve the problems of voids or hollows at the overlap in the crack-resistant felt surface layer 602, reduce a leveling process and save construction material costs.

[0070] like Figure 5 and 6 As shown, Figure 5This is a planar schematic diagram showing the overlapping state of the third and fourth crack-resistant felts in this embodiment. The third edge 60211 of the third crack-resistant felt 6021 overlaps with the fourth edge 60221 of the fourth crack-resistant felt 6022, forming a highly flat crack-resistant felt surface layer 602. This means that the crack-resistant felt surface layer 602 formed after the third and fourth crack-resistant felts 6021 and 6022 are overlapped with rough edges essentially constitutes a crack-resistant felt bottom layer. In practical engineering applications, since the surface area of ​​the wall to be protected varies, it is necessary to overlap crack-resistant felt adhesive layers of different areas to form a whole to cover the wall surface to be protected. The overlapping of the third crack-resistant felt 6021 and the fourth crack-resistant felt 6022 with rough edges provided in this embodiment can effectively solve the problem of overlap steps and overlap marks formed by the overlap between traditional crack-resistant felt adhesive layers.

[0071] In this embodiment of the application, the surface of the raw yarn of the third crack-resistant felt 6021 and the fourth crack-resistant felt 6022 is also subjected to heat insulation treatment. At the same time, heat insulation treatment is also performed during the impregnation process of the mesh felt. Such a dual pretreatment process can improve the heat insulation effect of the third crack-resistant felt 6021 and the fourth crack-resistant felt 6022, and can also improve the toughness of the third crack-resistant felt 6021 and the fourth crack-resistant felt 6022.

[0072] It should be noted that, Figure 5 This embodiment of the application shows a schematic diagram of the burr overlap state of the third and fourth anti-cracking felts. Figure 5 The gap between the third crack-resistant felt 6021 and the fourth crack-resistant felt 6022 is exemplary. After the third crack-resistant felt 6021 and the fourth crack-resistant felt 6022 are overlapped, a flat overlap surface can be formed between them, and there is no gap between them after the overlap (e.g., ...). Figure 6 As shown, after the third crack-resistant felt 6021 and the fourth crack-resistant felt 6022 are fully overlapped, the plane of the third crack-resistant felt 6021 and the plane of the fourth crack-resistant felt 6022 are in the same plane.

[0073] like Figure 2 As shown, the crack-resistant felt layer 60 also includes a waterproof felt adhesive layer 603, which is disposed between the crack-resistant felt bottom layer 601 and the crack-resistant felt top layer 602. In this embodiment, the waterproof felt adhesive layer 603 is composed of a special waterproof felt adhesive. By providing the waterproof felt adhesive layer 603 between the crack-resistant felt bottom layer 601 and the crack-resistant felt top layer 602, the overall structural stability and crack resistance of the crack-resistant felt layer 60 can be further improved.

[0074] like Figure 1As shown, in some embodiments, the heat-insulating and waterproof felt adhesive layer 50 includes a first felt adhesive layer and a second felt adhesive layer. The first felt adhesive layer is disposed on the surface of the insulation layer 30 facing away from the base wall 10, and the second felt adhesive layer is disposed on the surface of the first felt adhesive layer facing away from the insulation layer 30. In the embodiments of this application, the first and second felt adhesive layers can be composed of felt adhesive with heat insulation and waterproofing functions. By providing the first and second felt adhesive layers, the waterproof and heat insulation performance of the composite layer structure can be improved.

[0075] like Figure 1 As shown, in some embodiments, the felt-rubber composite layer wall shield further includes a cement mortar leveling layer 20 and an insulation layer 30. The cement mortar leveling layer 20 is disposed on the surface of the base wall 10, and the insulation layer 30 is disposed on the surface of the cement mortar leveling layer 20 facing away from the base wall 10. The insulation layer 30 is positioned between the cement mortar leveling layer 20 and the heat-insulating waterproof felt-rubber layer 50. By placing the cement mortar leveling layer 20 between the base wall 10 and the insulation layer 30, the overall flatness and aesthetics of the insulation layer 30 can be improved. Furthermore, by placing the insulation layer 30 on the outer surface of the base wall 10, it can provide thermal insulation, and the insulation layer 30 can block external heat from being transferred to the outside of the base wall 10, thus improving the insulation effect of the base wall 10.

[0076] like Figure 1 As shown, the insulation layer 30 is provided with an injection hole 101, which penetrates the insulation layer 30 and extends into the interior of the foundation wall 10. By providing the injection hole 101 on the insulation layer 30 and injecting adhesive or foaming agent into the injection hole 101, the hollowing of the insulation layer 30 can be effectively prevented; moreover, since the injection hole 101 penetrates the insulation layer 30 and extends into the interior of the foundation wall 10, the structural stability of the insulation layer 30 and the foundation wall 10 can also be improved.

[0077] In this embodiment of the application, the insulation layer 30 may be composed of block insulation boards or plaster mortar insulation materials.

[0078] like Figure 1As shown, in some embodiments, the felt-adhesive composite wall shield further includes an interface layer 40. The interface layer 40 is disposed on the surface of the original exterior wall paint finish layer 90 facing away from the base wall 10, and is located between the original exterior wall paint finish layer 90 and the heat-insulating waterproof felt adhesive layer 50. By disposing of the original exterior wall paint finish layer 90 on the surface of the insulation layer 30 facing away from the cement mortar leveling layer 20, the flatness and aesthetics of the composite layer can be improved. By disposing of the interface layer 40 on the surface of the original exterior wall paint finish layer 90 facing away from the insulation layer 30, and by disposing of the interface layer between the original exterior wall paint finish layer 90 and the heat-insulating waterproof felt adhesive layer 50, the bonding strength between the heat-insulating waterproof felt adhesive layer 50 and the original exterior wall paint finish layer 90 can be improved, and long-term structural stability can be maintained, preventing the heat-insulating waterproof felt adhesive layer 50 from falling off.

[0079] like Figure 1 As shown, in some embodiments, the felt-rubber composite wall shield further includes a finishing layer 80, which is disposed on the surface of the insulation layer 70 opposite to the crack-resistant felt base layer 601. The finishing layer 80 may be composed of modified silicone aerogel. By providing the finishing layer 80 on the surface of the insulation layer 70 opposite to the crack-resistant felt base layer 601, the aesthetic appearance of the composite layer surface can be improved.

[0080] like Figure 1 As shown, in some embodiments, the felt-rubber composite wall shield further includes a fixing pin 102. The first end of the fixing pin 102 penetrates the crack-resistant felt layer 60 and the heat-insulating and waterproof felt-rubber layer 50 and extends into the interior of the base wall 10, with the first end of the fixing pin 102 extending into the interior of the base wall 10 to a depth of not less than 25mm. The outer end face of the second end of the fixing pin 102 is flush with the outer surface of the crack-resistant felt layer 60.
