Description

Technical Field

[0001] This invention relates to the field of building energy conservation, and more particularly to a method and apparatus for heat insulation and decoration of building exterior walls. Background Technology

[0002] In recent years, driven by the national energy conservation and emission reduction policies, the application of thermal insulation layers on building exterior walls has become widespread. During the construction of thermal insulation layers on building exterior walls, insulation boards are typically bonded to the exterior wall using adhesive materials. After the insulation boards are fixed to the exterior wall, three layers of crack-resistant mortar are applied over them. Then, tiles or paint are applied over the crack-resistant mortar layers to form the exterior facade of the thermal insulation layer.

[0003] Due to the inherent water-sensitivity of insulation materials and issues with construction quality such as cracks in the roof, window sills, and exterior insulation layers, rainwater and snowmelt can seep into the insulation layers bonded to the building's exterior, causing leakage and frost heave. For example, when the exterior insulation layer cracks, rainwater and snowmelt can seep from the outside through these cracks into the internal insulation panels. Besides reducing the thermal performance of the building's exterior walls, this leakage and frost heave can also cause the insulation panels to delaminate and the exterior insulation layer to crack. Delaminated insulation panels and cracked exterior insulation layers pose a risk of detaching, leading to frequent incidents of detached insulation panels and exterior insulation layers falling on vehicles and injuring people.

[0004] Furthermore, when tiling over a crack-resistant mortar layer, cement mortar or other adhesive materials are used to bond the tiles to the wall. The reliability of the bond between the wall and the tiles relies entirely on the adhesive material. While this method offers the advantage of convenience and speed, as the adhesive material ages, the tiles are highly susceptible to detaching from the wall, potentially causing safety hazards. Therefore, for safety reasons, it is common practice to apply paint over the crack-resistant mortar layer instead of bonding tiles directly to it.

[0005] To enhance the aesthetics of the exterior facade of the insulation layer by applying bricks over the crack-resistant mortar layer, dry-hanging the bricks prevents them from falling off. Currently, the most common method for dry-hanging bricks is stone cladding. Dry-hanging stone-like bricks requires installing a frame structure such as angle iron on the wall. Due to the complex installation process and the high cost of stone, the installation cost of stone dry-hanging is relatively high.

[0006] Therefore, there is an urgent need to develop a new method and device for insulation and decoration of building exterior walls. This method should ensure insulation of the building exterior walls while preventing rainwater and snowmelt from seeping into the interior insulation layer from the exterior facade, thus preventing the insulation layer from falling off. It should also achieve an aesthetically pleasing exterior facade at a lower cost and promptly drain any leaked rainwater and snowmelt. Summary of the Invention

[0007] To achieve the aforementioned objectives, the present invention provides a method for thermal insulation and decoration of the exterior walls of a building, the method comprising:

[0008] Multiple first pipes are provided, which extend parallel to each other at certain intervals along a first direction and are fixed to the exterior wall of the building. The first direction is the height direction of the building.

[0009] A plurality of second pipes are provided, each connected to a plurality of first pipes along a second direction perpendicular to the first direction, and fixed to the exterior wall of the building, such that the plurality of first pipes and the plurality of second pipes form a square frame on the exterior wall of the building, and insulation material is laid in the square frame to form an insulation layer for insulating the exterior wall of the building; and

[0010] A mounting plate is provided; the mounting plate covers and secures the square frame.

[0011] The first and second pipes are heat-insulating pipes with hollow cavities.

[0012] According to one embodiment of the present invention, a plurality of third pipes are provided between the square frame and the hanging plate, the plurality of third pipes being parallel to and spaced apart from the first pipe of the square frame and fixed to the second pipe of the square frame, an insulation layer being laid between adjacent two third pipes, and the hanging plate being fixed to the third pipes.

[0013] The third tube is an insulated tube with a hollow cavity.

[0014] According to one embodiment of the present invention, one end of the mounting plate along the first direction has a insertion groove, and the other end along the first direction has an insertion protrusion, and two adjacent mounting plates are connected to each other along the first direction in a sealed and waterproof manner by the engagement of the insertion groove and the insertion protrusion.

[0015] According to one embodiment of the invention, the mortar surface and / or the surface facing the insulation layer of the hanging panel includes protruding reinforcing ribs.

[0016] According to one embodiment of the invention, the mounting plate is made of fiberglass and is at least 3 mm thick to ensure that the mounting plate has sufficient pull-out strength after the screws are driven into it.

[0017] According to one embodiment of the present invention, the mortar surface of the hanging panel is roughened to enhance the adhesion between the hanging panel and the crack-resistant mortar layer.

[0018] According to one embodiment of the invention, the method further includes providing self-tapping screws and nylon expansion bolts, the self-tapping screws being used to fix the mounting plate to the first pipe and the second pipe, and the nylon expansion bolts being used to fix the mounting plate to the exterior wall of the building.

[0019] According to one embodiment of the invention, it further includes interlocking shims for adjusting the verticality of the vertical installation of the mounting plate.

[0020] According to one embodiment of the invention, the method further includes providing a tile with stepped edges, and fixing the tile to the mounting plate by driving a self-tapping screw into the tile joint between the steps of two adjacent tiles so that the head of the self-tapping screw presses on the step.

[0021] The present invention also proposes an apparatus for insulation and decoration of the exterior walls of buildings, which is manufactured according to the above-described method for insulation and decoration of the exterior walls of buildings.

[0022] The present invention relates to a method and apparatus for thermal insulation and decoration of building exterior walls. By setting an impermeable hanging plate between the thermal insulation layer and the crack-resistant mortar layer of the building exterior wall, the method completely isolates the thermal insulation layer and the crack-resistant mortar layer. This ensures thermal insulation of the building exterior wall while preventing rainwater and snow from seeping into the internal thermal insulation layer through cracks in the exterior facade. It also prevents the thermal insulation layer from falling off and avoids cracking of the exterior facade of the thermal insulation layer due to leakage and frost heave. Furthermore, it allows for the secure adhesion of tiles to the outside of the crack-resistant mortar layer without them falling off. Thus, it achieves an aesthetically pleasing exterior facade of the thermal insulation layer at a lower cost and promptly drains leaked rainwater and snow. Attached Figure Description

[0069] To better understand this application, the following will be combined with... Figures 1 to 10 A method and apparatus for heat insulation and decoration of building exterior walls according to embodiments of this application will be described in detail.

[0070] Figure 1 This is a schematic diagram illustrating an apparatus for thermal insulation and decoration of a building exterior wall according to an embodiment of this application, installed on a building exterior wall without window openings. Figure 2 This is a schematic diagram illustrating an apparatus for thermal insulation and decoration of a building exterior wall, according to an embodiment of this application, installed on the exterior wall of a building with window openings. Figure 1-2 As shown, multiple vertical square tubes 1 extend parallel to each other in the vertical direction and are installed on the building's exterior wall 5 by expansion bolts 16. Multiple horizontal square tubes 1 extend in the horizontal direction and are perpendicularly connected to the vertically installed square tubes 1, and are also installed on the building's exterior wall 5 by expansion bolts 16. Thus, multiple vertically installed square tubes 1 and multiple horizontally installed square tubes 1 are fixed to the building's exterior wall 5 and are perpendicularly connected to each other to form a grid-like square frame structure.

[0071] Specifically, such as Figure 1As shown, multiple expansion bolt holes are drilled at corresponding positions on the exterior wall 5 of the building. The expansion bolts 16 fix multiple vertically installed square tubes 1 and multiple horizontally installed square tubes 1 to the exterior wall 5 of the building by means of their bolt heads abutting against the inner wall of the square tube 1 on the wall side.

[0072] The insulation material is laid within a grid-shaped frame structure to form the first insulation layer 3, which insulates the exterior wall 5 of the building. The insulation material can be selected according to needs. Currently, relatively mature lightweight, fire-retardant exterior wall insulation materials include rock wool, glass wool board, foamed cement, foamed glass, polystyrene foam board, and expanded clay concrete composite polystyrene imitation stone decorative insulation board.

[0073] After the first insulation layer 3 is laid in the grid-shaped square frame structure, the hanging plate 6 is covered and fixed to the square frame structure. The thickness of the hanging plate 6 is preferably not less than 3mm to ensure that the hanging plate 6 has sufficient pull-out strength after the screws are driven into it.

[0074] After covering and securing the cladding panel 6 to the square frame, apply a layer of crack-resistant mortar to the mortar surface of the cladding panel 6. The mortar surface of the cladding panel 6 can be roughened to enhance the adhesion between the mortar surface of the cladding panel and the crack-resistant mortar.

[0075] To further enhance the drainage of rainwater and snowmelt that has seeped into the exterior wall insulation layer, such as Figure 1-2 As shown, one or two vertically extending reinforcing pipes 2 are added between the grid-shaped square frame structure and the hanging plate 6. The reinforcing pipes 2 are parallel to the vertically extending square pipes 1 of the square frame structure and are fixed to the horizontally extending square pipes 1 of the square frame structure. A second insulation layer 4 is laid on the first insulation layer 3 between the vertically extending reinforcing pipes 2. The hanging plate 6 is also fixed to the vertically extending reinforcing pipes 2.

[0076] like Figures 3A-3D As shown, Figures 3A-3D A mounting plate 6 according to an embodiment of this application is shown. The mounting plate 6 is plate-shaped. Because fiberglass has advantages such as a low coefficient of thermal expansion close to that of a wall, higher tensile and impact strength than steel, wide weather resistance, and corrosion resistance, the mounting plate 6 is preferably made of fiberglass. The mounting plate 6 is at least 3 mm thick, preferably 3-5 mm thick, to ensure sufficient pull-out strength after screws are driven into it. The mounting plate 6 has symmetrically spaced transverse reinforcing ribs 9 on the mortar surface and the surface facing the insulation layer. One end of the mounting plate 6 along the building height direction has a groove 7, and the other end along the building height direction has a protrusion 8. Adjacent mounting plates 6 form a watertight seal through the groove 7 and the protrusion 8.

[0077] like Figures 4A-4B As shown, Figure 4A A square tube 1 according to an embodiment of this application is shown. Figure 4BA reinforcing tube 2 according to an embodiment of this application is shown. The square tube 1 and the reinforcing tube 2 are made of insulating material. Since fiberglass has advantages such as a low coefficient of thermal expansion close to that of a wall, higher tensile and impact strength than steel, wide weather resistance, and corrosion resistance, the square tube 1 and the reinforcing tube 2 are preferably made of fiberglass. The square tube 1 and the reinforcing tube 2 have a rectangular cross-section and a hollow inner cavity. Thus, the square tube 1 and the reinforcing tube 2 have two sets of opposing sides or tube walls.

[0078] Preferably, such as Figure 4A As shown, the square tube 1 has V-shaped grooves on both sides. These grooves can drain rainwater and snow that leaks into the insulation layer.

[0079] Preferably, such as Figure 4B As shown, one side of the reinforcing tube 2 has two raised vertical ribs. The vertical ribs protrude from this side to form a groove.

[0080] like Figure 4C As shown, Figure 4C This is an interlocking shim 10 used to adjust the vertical straightness of vertically installed square tubes and vertically installed reinforcing tubes. The interlocking shim 10 is a wedge-shaped shim with a long opening in the middle.

[0081] like Figure 5 As shown, in the case of uneven exterior wall surface, in order to ensure the vertical straightness of the vertical installation of square tube 1, two interlocking washers 10 are inserted into the gap between the wall-facing side of the vertically installed square tube 1 and the exterior wall 5 of the building from both sides of the vertically installed square tube 1 to clamp the vertically installed square tube 1, thereby ensuring the vertical straightness of the vertically installed square tube 1.

[0082] In addition, such as Figure 5 As shown, in order to ensure the vertical straightness of the vertical installation of the hanging plate 6, two interlocking washers 10 are inserted from both sides of the reinforcing tube 2 into the gap between the side of the vertically installed reinforcing tube 2 facing the hanging plate 6 and the side of the hanging plate 6 facing the insulation layer, thereby ensuring the vertical straightness of the vertically installed hanging plate 6.

[0083] In addition, multiple square tubes 1 are passed through... Figure 6A The straight connector 11 shown achieves a straight connection. The horizontal square tube 1 is connected via... Figure 6C The T-shaped connector 13 shown or via Figure 6B The cross connector 12 shown achieves a vertical connection with the vertical square tube 1.

[0084] Specifically, such as Figure 6A As shown, Figure 6AA straight connector 11 for connecting square tubes is shown. The cross-sectional shape of the straight connector 11 is approximately the same as that of the square tube 1, but the straight connector 11 has only three sides and also has a V-shaped groove. The cross-sectional dimension of the straight connector 11 is larger than that of the square tube 1. One square tube 1 is inserted into the opening at one end of the straight connector 11, and another square tube 1 is inserted into the opening at the other end of the straight connector 11, thereby connecting the two square tubes 1. A self-tapping screw can be driven into the overlapping portion of the straight connector 11 and the two square tubes 1, thereby fixing the straight connector 11 to the two square tubes 1.

[0085] Similarly, such as Figure 6B As shown, two vertical square tubes and two horizontal square tubes are cross-connected by a cross connector 12. Figure 6C As shown, two vertical square tubes and one horizontal square tube are connected in a T-shape by a T-connector 13.

[0086] like Figure 7A , Figure 7B and Figure 7C As shown, the upper end of a water-permeable bend 14 is inserted into the bottom of the vertically installed square tube 1, and a mesh plug 15 is installed at the lower end of the water-permeable bend 14 to ensure that mice and birds cannot enter the vertically installed square tube 1. A water-permeable bend is installed near the ground on the vertically installed square tube, which not only drains rainwater and snow that leaks into the insulation layer but also indicates the location of the leak.

[0087] In addition, the vertical square tube 1 and the horizontal square tube 1 are connected by... Figure 8A The expansion bolts 16 shown are fixed to the exterior wall 5 of the building. The hanging plate 6 is... Figure 8B The nylon expansion bolt 18 shown is also fixed to the exterior wall 5 of the building. The hanging plate 6 is... Figure 8C The self-tapping screw 17 shown is fixed to the vertical square tube 1, the horizontal square tube 1, and the reinforcing tube 2.

[0088] Figure 9 A structural cross-sectional view is shown of a device for heat insulation and decoration of a building exterior wall, according to an embodiment of this application, installed on the exterior wall of the building. Figure 9 As shown, the horizontal square tube 1 is fixed to the exterior wall 5 of the building by expansion bolts 16. The vertical reinforcing tube 2 is fixed to the horizontal square tube 1 with its groove facing the hanging plate 6. The hanging plate 6 is fixed to the vertical reinforcing tube 2 by self-tapping screws 17, with the end of the hanging plate 6 having a spigot facing downwards. A crack-resistant mortar layer 19 is applied to the outside of the hanging plate 6, and then paint or real stone paint 20 is brushed on the outside of the crack-resistant mortar layer 19. A water leakage elbow 14 is installed at the position of the vertically installed square tube 1 near the ground, and a mesh plug 15 is installed at the lower end of the water leakage elbow 14.

[0089] like Figure 10 As shown, after applying the crack-resistant mortar layer 19 to the mortar surface of the hanging board 6, paint or real stone paint 20 is applied to the crack-resistant mortar layer 19.

[0090] Or, such as Figures 11-12 As shown, after applying the crack-resistant mortar layer 19 to the mortar surface of the hanging board 6, small ceramic tiles 21 or large ceramic tiles 22 with stepped edges are pasted onto the crack-resistant mortar layer 19.

[0091] Then, self-tapping screws are used to drive into the brick joints between the steps of two adjacent small tiles 21 or large tiles 22, so that the small tiles 21 or large tiles 22 are firmly locked and fixed on the hanging plate 6, thereby firmly fixing the small tiles 21 or large tiles 22 to the crack-resistant mortar layer 19 without falling off.

[0092] In addition, such as Figure 2 As shown, in order to prevent water leakage from the windowsill and to prevent water from seeping into the insulation layer, a window opening guard frame 23 is installed on the windowsill. Figure 13A yes Figure 2 A cross-sectional view of the window opening guardrail. (See attached image.) Figure 13A As shown, the window opening guard frame 23 is L-shaped, with one side being a double-layered, long-depth profile and the other side a single-layered guard plate. The two window opening guard frames 23 are connected by... Figure 13B and Figure 13C The right-angle plug shown achieves a right-angle connection. Preferably, the window opening guard frame 23 is made of fiberglass.

[0093] In addition, to prevent water leakage at the corners of the building's exterior walls and to prevent water from seeping into the insulation layer, cladding panels are installed at the corners of the building's exterior walls. Figure 13D The yin and yang corner protectors shown. (Example) Figure 5 As shown, the corner protectors are installed on the outside of the hanging plates 6 at the inside and outside corners of the building's exterior wall 5, and then an anti-crack mortar layer 19 is applied to the outside of the corner protectors. Preferably, the corner protectors are made of fiberglass.

[0094] like Figure 13D As shown, each of the two right-angled sides of the yin and yang corner protectors has a groove, which is used to fix the self-tapping screws of the yin and yang corner protectors to the hanging plate in the groove, so as to reduce the thickness of the crack-resistant mortar layer.

[0095] The structure of the device for insulation and decoration of building exterior walls described in this application will be better illustrated and understood through the following method.

[0096] The following describes a method for using thermal insulation and decoration materials for building exterior walls according to embodiments of this application:

[0097] 1) Install multiple vertical square tubes on the exterior wall of the building.

[0098] First, multiple square tubes 1 are vertically installed on the exterior wall 5 of the building, with a certain distance between them. Before installing the square tubes 1 onto the exterior wall 5, expansion bolt holes are drilled in the exterior wall 5. Then, the square tubes 1 are placed vertically with the side having a V-shaped groove facing the exterior wall 5. Next, expansion bolts 16 pass through the cavity wall of the vertical square tubes 1 and enter the expansion bolt holes in the exterior wall 5. The expansion bolts 16 secure the square tubes 1 to the exterior wall 5 by abutting the bolt head against the inner wall of the square tube 1 on the wall side.

[0099] When vertically installing the square tube 1 onto the exterior wall 5 of the building, it can be installed... Figure 4C The interlocking gaskets 10 shown are used to ensure the vertical straightness of the vertically installed square tube 1.

[0100] 2) Form a square frame

[0101] The horizontal square tubes 1 are vertically connected to the vertically installed square tubes 1 via T-connectors 12 or cross connectors 13, and the horizontally installed square tubes 1 are fixed to the exterior wall 5 of the building with expansion bolts 16. Multiple vertically installed square tubes 1 and multiple horizontally installed square tubes 1 form a grid-like square frame of appropriate size.

[0102] 3) Lay the first layer of insulation

[0103] Within the formed grid-like square frame, insulation material is laid to form the first insulation layer 3. The thickness of the first insulation layer 3 is on the same vertical plane as the square frame formed by the vertically and horizontally installed square tubes 1. The insulation material is adhered to the exterior wall 5 of the building using dotted cement, without covering the entire surface of the insulation material with cement mortar to prevent rainwater and snow from seeping into the exterior wall.

[0104] 4) Install vertical reinforcing pipes

[0105] To enhance the drainage of rainwater and snowmelt seeping into the building's exterior walls, one or two vertical reinforcing pipes 2 are added between two adjacent vertical square tubes 1 of the square frame. These vertical reinforcing pipes 2 are perpendicularly connected to the horizontal square tubes 1 of the square frame and parallel to the vertical square tubes 1. The purpose of installing the reinforcing pipes 2 is twofold: first, to drain water seeping between the insulation layer and the cladding panel 6; and second, to vertically level the cladding panel 6.

[0106] Preferably, a vertical reinforcing tube 2 can be installed between two adjacent vertical square tubes 1 of the square frame. Of course, it is also feasible not to install a vertical reinforcing tube 2 between two adjacent vertical square tubes 1 of the square frame.

[0107] 5) Lay the second layer of insulation.

[0108] Between two adjacent reinforcing pipes 2, a second insulation layer 4 is laid on top of the first insulation layer 3. Specifically, multiple insulation boards are stacked vertically between two adjacent reinforcing pipes 2 to form the second insulation layer 4.

[0109] The first insulation layer 3 and the second insulation layer 4 preferably use non-combustible rock wool or graphene polystyrene insulation materials, and the surface of the rock wool is treated with water-repellent treatment.

[0110] Since square tube 1 and reinforcing tube 2 are preferably made of fiberglass, and the thermal conductivity of fiberglass is higher than that of rock wool or graphene polystyrene board, the rock wool or graphene polystyrene board can be appropriately thickened to compensate for the insulation loss of the small area of ​​fiberglass square tube 1.

[0111] Alternatively, the first layer of insulation 3 may be laid before the vertical reinforcing pipe 2 is installed, and the second layer of insulation 4 may be left unlaid or laid after the vertical reinforcing pipe 2 is installed.

[0112] Alternatively, only the first layer of insulation 3 can be laid after the vertical reinforcing pipe 2 is installed.

[0113] Alternatively, after installing the vertical reinforcing pipe 2, a first insulation layer 3 and a second insulation layer 4 can be laid.

[0114] Of course, it is also feasible to not install vertical reinforcing pipes 2 between two adjacent vertical square tubes 1 of the square frame, and not lay a second layer of insulation 4.

[0115] 6) Fixed mounting plate

[0116] The cladding plate 6 is fixed to the reinforcing tube 2, the horizontal square tube 1, and the vertical square tube 1 of the square frame using self-tapping screws 17. Since the building's exterior wall and fiberglass have the same coefficient of thermal expansion and contraction, the cladding plate 6 is preferably made of fiberglass. The cladding plate 6 is at least 3mm thick, preferably 3-5mm thick, to ensure sufficient pull-out strength after the screws are driven into it. The cladding plate 6 has symmetrically spaced horizontal reinforcing ribs 9 on both the mortar surface and the surface facing the insulation layer. One end of the cladding plate 6 along the building height has a groove 7, and the other end along the building height has a protrusion 8. Adjacent cladding plates 6 form a watertight seal through the engagement of the groove 7 and the protrusion 8. Therefore, the cladding plate 6 has the advantages of high tensile, bending, and impact resistance, high oxygen index (non-combustible), and watertightness when interlocked.

[0117] In addition, the mounting plate 6 can also be fixed to the exterior wall 5 of the building by means of nylon expansion bolts 18.

[0118] Multiple mounting plates 6 are joined together vertically through the cooperation of insertion slots 7 and insertion protrusions 8, while the lateral joints of the mounting plates are located at the grooves of the vertical square tube 1 and / or the grooves of the vertical reinforcing tube 2. This design offers two advantages: firstly, external rainwater and snowmelt can flow into the grooves of the vertical square tube 1 and / or the vertical reinforcing tube 2; secondly, vertical expansion joints of the mounting plates 6 are provided at the grooves.

[0119] To ensure the vertical straightness of the vertically installed mounting plate 6, two interlocking washers 10 are inserted from both sides of the reinforcing tube 2 into the gap between the side of the vertically installed reinforcing tube 2 away from the building's exterior wall and the side of the mounting plate 6 facing the insulation layer, thereby ensuring the vertical straightness of the vertically installed mounting plate 6.

[0120] Of course, it is also feasible to not install the vertical reinforcing tube 2 between the two adjacent vertical square tubes 1 of the square frame, and directly fix the hanging plate 6 to the horizontal square tube 1 and the vertical square tube 1 of the square frame.

[0121] 7) Lay a thin layer of coarse fiberglass mesh anti-crack mortar

[0122] A thin layer of crack-resistant mortar waterproof protective layer is laid on the outside of the mortar surface of the hanging board 6 using coarse fiberglass mesh, crack-resistant mortar, and high-adhesion weather-resistant two-component adhesive, and then leveled with long nylon expansion bolts.

[0123] 8) Apply multiple layers of crack-resistant mortar.

[0124] 9) Apply decoration outside the crack-resistant mortar layer.

[0125] Paint or stone-like paint 20 is applied to the outside of the crack-resistant mortar layer 19, or small tiles 21 or large tiles 22 are pasted on. When pasting small tiles 21 or large tiles 22, self-tapping screws 17 are used to drive into the gaps of small tiles 21 or large tiles 22 to secure them to the hanging plate 6, thereby firmly fixing small tiles 21 or large tiles 22 to the crack-resistant mortar layer 19 and preventing them from falling off.

[0126] Specifically, the thickness of the large ceramic tile 22 is 10-13mm, and the grout spacing on all four sides is 10mm. M6X30d self-tapping screws 17 are driven into the grout lines on all four sides of the large ceramic tile 22. Slightly adjusting the position of the large ceramic tile 22 will prevent the horizontal ribs of the mounting plate 6 from overlapping with the self-tapping screws 17. Because the thickness of the large ceramic tile 22 is 10-13mm, a few holes can be drilled in the middle of the large ceramic tile 22 to create concealed fasteners, thereby increasing its flatness and adhesive strength.

[0127] To increase adhesion strength, steps are provided around the small tile 21 or large tile 22. The purpose is to ensure that when the self-tapping screw 17 is driven into the mounting plate 6 from the tile joint, the head of the self-tapping screw 17 can directly press against the step of the small tile 21 or large tile 22. This has two advantages: first, it ensures that all self-tapping screws 17 are driven to the same depth; second, it presses the small tile 21 or large tile 22 under the head of the self-tapping screw 17, ensuring that the small tile 21 or large tile 22 does not fall off the crack-resistant mortar layer 19.

[0128] The method and apparatus for thermal insulation and decoration of building exterior walls of the present invention have the following advantages:

[0129] 1. In this invention, an impermeable panel is installed between the building's exterior wall insulation layer and the crack-resistant mortar layer to completely isolate them. This ensures insulation of the building's exterior wall while preventing rainwater and snow from seeping into the interior insulation layer through the cracked exterior surface. The panel has interlocking grooves and protrusions, allowing adjacent panels to fit vertically together to form an impermeable seal, thus preventing rainwater and snow from seeping into the interior insulation layer through the cracked exterior surface.

[0130] 2. In this invention, by setting an impermeable hanging plate between the exterior wall insulation layer and the crack-resistant mortar layer, the exterior wall insulation layer and the crack-resistant mortar layer are completely separated. This ensures the insulation of the exterior wall of the building, while also preventing the crack-resistant mortar layer adjacent to the insulation layer from cracking due to leakage and frost heave, and also preventing the debonded insulation layer from falling off to the outside.

[0131] 3. This invention also provides small or large ceramic tiles with stepped edges on all four sides. After applying a crack-resistant mortar layer to the mortar surface of the cladding board, the small or large ceramic tiles with stepped edges are adhered to the crack-resistant mortar layer. Self-tapping screws are then driven into the brick joints between the steps of adjacent small or large ceramic tiles, so that the heads of the self-tapping screws press against the steps, securing the small or large ceramic tiles firmly to the cladding board. This ensures that the small or large ceramic tiles do not detach from the crack-resistant mortar layer, changing the traditional practice of not being able to adhere small or large ceramic tiles to the insulation layer of building exterior walls. Compared to the dry-hanging stone method, small or large ceramic tiles are much cheaper, thus achieving an aesthetically pleasing exterior facade for the insulation layer at a lower cost.

[0132] 4. In this invention, the square tube has a hollow inner cavity and is provided with a figure-eight shaped groove, which can effectively and promptly drain rainwater and snow that leaks into the insulation layer on the exterior wall. A reinforcing tube with a hollow inner cavity is also provided, which can similarly effectively and promptly drain rainwater and snow that leaks into the insulation layer on the building's exterior wall. The insulation material is adhered to the building's exterior wall using dotted cement, without needing to completely cover the adhesive surface with cement mortar, leaving a gap between the insulation material and the building's exterior wall for water drainage, which can also effectively and promptly drain rainwater and snow that leaks into the insulation layer on the exterior wall. A leakage bend is installed near the ground on the vertically installed square tube, which not only drains rainwater and snow that leaks into the insulation layer but also indicates the location of the leak.
