Description

Technical Field

[0001] This utility model relates to a thermal insulation and decorative composite panel and an external wall insulation structure, belonging to the field of external wall insulation technology. Background Technology

[0002] Standard-panel thermal insulation and decorative composite panels are prefabricated in factories, reducing secondary environmental pollution and improving the "manufacturing, transportation, and installation" construction technology of building exterior insulation systems, thus promoting technological progress in green and energy-saving construction projects. However, existing conventional exterior wall insulation and decorative integrated panel construction technologies have shortcomings:

[0003] (1) The boards are joined by flat joints, which are prone to water seepage and thermal bridging. Especially during the freezing period, when rainwater enters the joints, the board joints are easily damaged under the action of freeze-thaw cycles, causing the boards to fall off.

[0004] (2) The method of connecting the board to the wall is to first manually groove the upper and lower edges of the board at the connecting parts. Manual grooving can easily damage the board. After grooving, the connecting parts are directly inserted into the groove and then connected to the wall. If this connection method is subjected to external force, the board is easily damaged and falls off because the contact area between the tension point of the connecting parts and the board is small.

[0005] (3) The corners and the area around the window openings are made by cutting and assembling on site. The corners and the area around the window openings (especially the lower window sill) are very prone to water seepage, cracking and damage.

[0006] (4) Most thermal insulation panels are made of materials such as calcium silicate board. These materials have a large density. In order to prevent the composite board from being overweight per unit area, the panel thickness is generally controlled at around 10mm. Therefore, after the groove is cut on the 10mm panel, the tensioned position is easily damaged, which can easily cause the safety hazard of the board falling off. Summary of the Invention

[0007] The technical problems to be solved by this utility model are: how to solve the problems of easy water seepage and thermal bridging at the joints between standard insulated decorative composite panels; the problem that grooving on standard insulated decorative composite panels can easily cause damage to the panels and lead to detachment; the problem that the external corners and the area around window openings are prone to water seepage, cracking and damage; and the problem that existing insulation panel materials have a large density, and in order to prevent the composite panel from being too heavy per unit area, the panel thickness is relatively thin, and the tensioned parts are easily damaged after grooving, which can easily lead to the safety hazard of the panel falling off.

[0015] The connecting tenons are divided into upper and lower connecting tenons and single-sided connecting tenons. The horizontal plate of the upper and lower connecting tenons is fixedly connected to the middle of one side of the vertical plate. The upper and lower ends of the vertical plate of the upper and lower connecting tenons are inserted into the mortises of the reinforcing members of the two adjacent thermal insulation and decorative composite plates and into the long groove of the back plate. The horizontal plate of the single-sided connecting tenon is fixedly connected to one side of the vertical plate.

[0025] The structures of the window frame top insulation and decoration composite panel, the window frame and window sill insulation and decoration composite panel, the left window frame insulation and decoration composite panel, and the right window frame insulation and decoration composite panel are all the same as the structure of the standard panel insulation and decoration composite panel.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The thermal insulation and decorative composite board has tongue and groove joints around its special foamed ceramic panel, which serves the following purposes:

[0028] (1) It can facilitate accurate positioning during installation;

[0029] (2) When installing, the boards form an S-shaped overlap with the tongue and groove joints, which makes the thermal insulation and decorative composite board self-waterproof and reduces the generation of thermal bridges from its structure, thus completely solving the problem of water seepage in the board joints causing leakage in the exterior wall.

[0030] 2. In the panel structure of the thermal insulation and decorative composite board, U-shaped reinforcing members with mortises are positioned at the tension points of the upper and lower edges of the special foamed ceramic panel and the wall connection parts (i.e., upper and lower connecting tenons and supports). Their function is as follows:

[0031] (1) The reinforcing member is provided with mortise holes, which can be accurately positioned and the quality controlled during construction, and the mortise holes will not be damaged when subjected to force;

[0032] (2) The special foamed ceramic panel is equipped with a U-shaped reinforcing member with mortise holes at the tension position and is connected with the thermal insulation and decorative composite panel to form an integral whole. When the mortise holes are under stress, the stress surface with the thermal insulation and decorative composite panel is enlarged, the stress strength is increased, and the thermal insulation and decorative composite panel is not easily damaged when under stress.

[0033] (3) The reinforcing member expands the stress surface of the mortise and the thermal insulation decorative composite board when the mortise is stressed. When the upper and lower connecting tenons are connected during installation, the force is transferred to the reinforcing member when the tenon is pulled into the mortise. The force is then transferred to the thermal insulation decorative composite board. The contact area between the reinforcing member and the special foamed ceramic panel is increased, and the board is less likely to be damaged when it is pulled. This improves the connection strength between the connecting member and the board.

[0034] (4) The reinforcement component solves the problem that conventional external wall insulation and decorative composite board tie components are directly grooved on the board opening for tension, which makes the tension points on the board very easy to be damaged, causing the board to fall off and causing safety accidents.

[0035] 3. The support components facilitate the horizontal positioning of the top edge of the thermal insulation and decorative composite panel and support the weight of each panel, thus distributing the weight of the panels on the wall in an orderly manner.

[0036] 4. Specialized assemblies with mortise and tenon joints (including reinforcing members on the upper and lower edges of the board, upper and lower connecting tenons for connecting the upper and lower thermal insulation and decorative composite boards, supporting members for connecting to the wall, bolts, and expansion bolts) and the tongue and groove structure of the thermal insulation and decorative composite board are adopted, which makes the thermal insulation and decorative composite board more convenient, accurate and strong when assembled on site, and can more effectively prevent the board from falling off.

[0050] Figure 14 An exploded view of the overall window frame insulation and decorative composite panel. Detailed Implementation

[0051] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0052] This utility model provides a standard thermal insulation and decorative composite board 101, such as... Figures 1-3As shown, it includes a standard board-specific foamed ceramic panel 102 located on the outer side and a thermal insulation material layer 103 located on the inner side. The standard board-specific foamed ceramic panel 102 and the thermal insulation material layer 103 are compositely connected or bonded together.

[0053] The periphery of the standard board special foamed ceramic panel 102 (i.e. Figure 1 The standard-grade foamed ceramic panel 102 has tongue and groove joints on all sides (top, bottom, left, and right). It comprises a two-layer structure: a front panel 1022 and a rear panel 1021. The front and rear panels are identical in shape and size. Vertically, the front panel 1022 is positioned lower than the rear panel 1021. Horizontally, the positions of the front and rear panels are staggered, forming a stepped, tongue-and-groove joint. The standard-grade foamed ceramic panel 102 is a one-piece molded structure.

[0054] The insulation material layer 103 is surrounded by a mortar layer 105. The thickness of the mortar layer 105 is generally about 5mm. The structure formed by the insulation material layer 103 and the mortar layer 105 wrapped around it is the same in shape and size as the back plate 1021, and their positions on the top, bottom, left and right (i.e., the perimeter) are aligned with each other.

[0055] At least two standard plate connectors 104 are provided on the upper and lower sides of the rear plate 1021, respectively. Each standard plate connector 104 has a mortise hole 1041 in the middle. The standard plate connector 104 is a long strip structure with a U-shaped cross-section, that is, it is sandwiched around the perimeter of the rear plate 1021. One side of the standard plate connector 104 is inserted between the front plate 1022 and the rear plate 1021, and the other side is inserted between the rear plate 1021 and the mortar layer 105, or passes through the mortar layer 105 and is inserted between the rear plate 1021 and the insulation material layer 103. A long groove matching the mortise hole 1041 is provided on the rear plate 1021 at the location of the mortise hole 1041.

[0056] This utility model also provides an external wall insulation structure, such as Figure 4 , Figure 6 As shown, it includes multiple standard thermal insulation and decorative composite panels 101 and a wall. Each standard thermal insulation and decorative composite panel 101 is fixed with upper and lower connecting tenons 106, which are fixed to the mortar layer 105. Multiple support members 107 are fixed to the wall, and each standard thermal insulation and decorative composite panel 101 is mounted on the corresponding multiple support members 107. Any two adjacent standard thermal insulation and decorative composite panels 101 are connected by tongue and groove inlay around the perimeter of the standard panel special foamed ceramic panel 102.

[0057] Because the front panel 1022 of the standard panel special foamed ceramic panel 102 is positioned lower than the rear panel 1021, the top surface of the front panel 1022 of the lower standard panel special foamed ceramic panel 102 is higher than the bottom surface of the rear panel 1021 of the upper standard panel special foamed ceramic panel 102. This prevents rainwater from entering the interior through the gap between the two adjacent standard panel insulation and decorative composite panels 101 during windy and rainy weather, thus achieving a waterproof function.

[0058] like Figure 5 As shown, the upper and lower connecting tenon 106 includes a horizontal plate 1062 and a vertical plate 1063. One side of the horizontally arranged horizontal plate 1062 is fixedly connected to the middle position of one side of the vertically arranged vertical plate 1063 in the vertical direction. A nut 1061 is fixed on the bottom surface of the horizontal plate 1062 (i.e., the lower end surface when horizontally arranged). The horizontal plate 1062 has a through hole communicating with the nut 1061. The position of the nut 1061 does not exceed the left and right boundaries of the vertical plate 1063. In this embodiment, the nut 1061 is located in the middle position of the horizontal plate 1062.

[0059] In use, the nut 1061 is pre-embedded in the mortar layer 105, or a groove for the nut 1061 is opened in the mortar layer 105, and the nut 1061 is placed in the groove. Figure 8 As shown, the upper and lower ends of the longitudinal plate 1063 are inserted into the mortises 1041 of the standard plate connectors 104 on the two adjacent standard plate thermal insulation and decorative composite panels 101 and into the long slots of the rear plate 1021.

[0060] like Figure 7 As shown, the support member 107 includes two bent edges, namely a bent vertical plate 1071 and a bent horizontal plate 1075. A first oblong hole 1072 is provided in the middle of the bent vertical plate 1071, through which a first expansion bolt 109 can be used to fix the support member 107 to the wall. A second oblong hole 1073 is provided in the middle of the bent horizontal plate 1075, through which a bolt 108 (in this embodiment, using...) can be used... An M6 bolt passes through the through hole on the upper and lower connecting tenons 106 and is fastened to the nut 1061, thereby fixing the support 107 onto the upper and lower connecting tenons 106. A limiting socket 1074 is provided at the end of the bent horizontal plate 1075 (on the opposite side of the bent vertical plate 1071). The width of the limiting socket 1074 matches the width of the vertical plate 1063 on the upper and lower connecting tenons 106, so that the vertical plate 1063 is placed inside the limiting socket 1074 during installation.

[0061] like Figure 8As shown, the standard panel insulation and decorative composite board 101 is supported on the wall by the support member 107, preventing the standard panel insulation and decorative composite board 101 from moving up and down. The connection between the upper and lower connecting tenons 106 and the support member 107, as well as the limiting of the upper and lower connecting tenons 106 and the standard panel connector 104, limit the standard panel insulation and decorative composite board 101, preventing the standard panel insulation and decorative composite board 101 from moving left and right or forward and backward.

[0062] An external wall insulation structure, further comprising an integral external corner insulation and decorative composite panel 111 and an integral window frame insulation and decorative composite panel.

[0063] like Figures 9-12 As shown, the structure of the integral external corner insulation and decorative composite panel 111 is the same as that of the standard panel insulation and decorative composite panel 101, except that its shape differs depending on the installation position. The standard panel insulation and decorative composite panel 101 is a standard panel, while the integral external corner insulation and decorative composite panel 111 is a bent corner structure. The integral external corner insulation and decorative composite panel 111 includes an integral external corner special foamed ceramic panel 112, a first external corner connector 113, an insulation material layer 103, and a mortar layer 105. The positional and connection relationships of the integral external corner special foamed ceramic panel 112 in the integral external corner insulation and decorative composite panel 111 are the same as those of the standard panel special foamed ceramic panel 102 in the standard panel insulation and decorative composite panel 101. Each first external corner connector 113 has at least two mortise holes 1041, respectively located on both sides of the external corner, i.e., on the two bent edges of the first external corner connector 113.

[0064] The overall external corner insulation and decorative composite panel 111 is composed mainly of a first external corner connector with a certain strength, whose function is as follows:

[0065] (1) Ensure the angle of the corner plate is properly positioned;

[0066] (2) Prevent deformation and damage to the corner plates;

[0067] (3) Precise positioning of the corner plate during installation.

[0068] The perimeter of the integral external corner insulation and decorative composite panel 111 is provided with high and low tongue and groove joints. During installation, the high and low tongue and groove joints of each integral external corner insulation and decorative composite panel 111 are combined with the tongue and groove joints of adjacent integral external corner insulation and decorative composite panels 111 to form a self-waterproofing system that reduces the generation of thermal bridges. First external corner connectors are set on the upper and lower edges of the integral external corner insulation and decorative composite panel 111 to strengthen the overall structure of the integral external corner insulation and decorative composite panel 111. Then, it is connected to the wall through combined iron parts (i.e., first external corner connectors, upper and lower connecting tenons, and support parts). The construction is convenient, precise, and firm, and it more effectively prevents damage to the external corner panels of the building.

[0069] like Figure 14 As shown, the overall window frame insulation and decorative composite panel consists of a window frame top insulation and decorative composite panel 115 (with tongue and groove structure) installed around the window opening, a window frame sill insulation and decorative composite panel 117, a left window frame insulation and decorative composite panel 119, and a right window frame insulation and decorative composite panel 121, as well as special assembly components with mortise and tenon joints (including standard plate connectors 104, upper and lower connecting tenons 106, support components 107, bolts 108, first expansion bolts 109, single-sided connecting tenons 123, second external corner connectors 124, third external corner connectors 125, inverted U-shaped fixing components 126, second expansion bolts 127, expansion bolt tubes 128, window frame connectors 129, and fourth external corner connectors 130), which are manufactured in the factory and then assembled on site. Its functions include:

[0070] (1) The window frames of each part (including the window frame top insulation and decoration composite board 115, the window frame and window sill insulation and decoration composite board 117, the left window frame insulation and decoration composite board 119, and the right window frame insulation and decoration composite board 121) are constructed with high and low tongue and groove around each board. During installation, the high and low tongue and groove are combined with the tongue and groove of the adjacent board to form a self-waterproofing system and reduce the generation of cold and heat bridges.

[0071] (2) The window frame and window sill insulation and decoration composite board 117 is a semi-basin type self-waterproof structure with a certain slope, and a water-blocking part of a certain height is set on the inside, which can completely solve the stubborn problem of leakage in the window sill area.

[0072] (3) The special foamed ceramic panel 118 for window frame and window sill is provided with an inverted U-shaped fastener 126 at the tension position. One end is joined with the board to form an integral whole, and the other end is connected to the wall through the second expansion bolt 127. When under force, the force-bearing surface with the board is expanded, the force strength is increased, and the board is not easily damaged when under force, which further improves the connection between the window frame and window sill thermal insulation decorative composite panel 117 and the wall.

[0073] (4) A second external corner connector 124 is installed below the window frame and windowsill insulation and decorative composite panel 117. After being connected to the wall, it can effectively support the weight of the window frame and windowsill insulation and decorative composite panel 117, so that the weight of the insulation board on the wall is distributed in an orderly manner.

[0074] (5) All window frames (including the top insulation and decorative composite board 115, the window frame and windowsill insulation and decorative composite board 117, the left window frame insulation and decorative composite board 119, and the right window frame insulation and decorative composite board 121) have a high and low tongue and groove waterproof structure at the connection points. Adjacent components are spliced ​​using special mortise and tenon joints (including standard plate connector 104, upper and lower connecting tenons 106, support 107, bolt 108, first expansion bolt 109, single-sided connecting tenon 123, second external corner connector 124, third external corner connector 125, inverted U-shaped fixing 126, second expansion bolt 127, expansion bolt tube 128, window frame connector 129, and fourth external corner connector 130), and are anchored to the wall with connectors. The outside of the window frame has a tongue and groove cover structure to connect with the standard plate of the wall, which serves both aesthetic and waterproof purposes.

[0075] The structures of the window frame top insulation and decoration composite panel 115, the window frame and window sill insulation and decoration composite panel 117, the left window frame insulation and decoration composite panel 119, and the right window frame insulation and decoration composite panel 121 are all the same as those of the standard panel insulation and decoration composite panel 101. The difference is:

[0076] When the standard panel insulation and decorative composite panel 101 is replaced with the window frame top insulation and decorative composite panel 115, the standard panel special foamed ceramic panel 102 is replaced with the window frame top special foamed ceramic panel 116. While using the standard panel connector 104, a window frame connector 129 is added.

[0077] When the standard panel insulation and decoration composite panel 101 is replaced with the window frame and window sill insulation and decoration composite panel 117, the standard panel special foamed ceramic panel 102 is replaced with the window frame and window sill special foamed ceramic panel 118.

[0078] When the standard panel insulation and decorative composite panel 101 is replaced with the left window frame insulation and decorative composite panel 119, the standard panel special foamed ceramic panel 102 is replaced with the left window frame special foamed ceramic panel 120.

[0079] When the standard panel insulation and decorative composite panel 101 is replaced with the right window frame insulation and decorative composite panel 121, the standard panel special foamed ceramic panel 102 is replaced with the right window frame special foamed ceramic panel 122.

[0080] The difference between the foamed ceramic panel 116 for the top of the window frame, the foamed ceramic panel 118 for the window frame and windowsill, the foamed ceramic panel 120 for the left window frame, and the foamed ceramic panel 122 for the right window frame lies in their different shapes due to their installation positions.

[0081] The second external corner connector 124, the third external corner connector 125, and the fourth external corner connector 130 are all fixed to the wall (or wall surface), and their structure is the same as that of the support member 107 without the limit socket 1074. The window frame and window sill insulation and decorative composite panel 117 is supported by the second external corner connector 124, and the top window frame insulation and decorative composite panel 115, the left window frame insulation and decorative composite panel 119, and the right window frame insulation and decorative composite panel 121 are respectively supported by the third external corner connector 125. The top window frame insulation and decorative composite panel 115 is provided with the fourth external corner connector 130 and the third external corner connector 125 for supporting other insulation and decorative composite panels.

[0082] The standard plate connector 104 at the top of the window frame top insulation and decorative composite panel 115 is connected to the standard plate connector 104 on other composite panels through a third external corner connector 125 and an upper and lower connecting tenon 106. The side of the window frame top insulation and decorative composite panel 115 is also fitted with a window frame connector 129, which is connected to the wall through a fourth external corner connector 130.

[0083] The standard plate connector 104 at the bottom of the window frame top insulation and decorative composite panel 115 is connected to the standard plate connector 104 at the top of the right window frame insulation and decorative composite panel 121 and the left window frame insulation and decorative composite panel 119 respectively through another third external corner connector 125 and another upper and lower connecting tenon 106.

[0084] The standard plate connectors 104 at the bottom of the right window frame insulation and decorative composite panel 121 and the left window frame insulation and decorative composite panel 119 are respectively connected to the standard plate connectors 104 at the top of the window frame and window sill insulation and decorative composite panel 117 through a third external corner connector 125 and an upper and lower connecting tenon 106.

[0085] The standard board connector 104 at the bottom of the window frame and windowsill insulation and decorative composite panel 117 is connected to the second external corner connector 124 via a single-sided connecting tenon 123. An inverted U-shaped fastener 126 is also fitted onto the top side of the window frame and windowsill insulation and decorative composite panel 117. The inverted U-shaped fastener 126 is fixedly connected to the wall via a second expansion bolt 127 and an expansion bolt tube 128.

[0086] In this embodiment, the standard plate connector 104, the upper and lower connecting tenons 106, the support 107, the first external corner connector 113, the single-sided connecting tenon 123, the second external corner connector 124, the third external corner connector 125, the inverted U-shaped fixing part 126, the window frame connector 129, and the fourth external corner connector 130 are all made of metal, and low-cost galvanized iron products can be selected; of course, if cost is not a consideration, other materials can be selected, such as waterproof and rustproof stainless steel, high-hardness steel, etc.

[0087] Each thermal insulation and decorative composite panel is bonded to the wall surface by an adhesive mortar layer 110.

[0088] like Figure 13 As shown, each thermal insulation and decorative composite panel can also be manufactured using a mold-type construction method (post-filling insulation method), as follows:

[0089] After completing the standard foamed ceramic panel 102 with tongue and groove structure, the foamed ceramic panel 112 for integral external corners, and the foamed ceramic panels for window frames in various parts, they are assembled and fixed on site. During assembly, space for insulation material is left between each panel and the wall (i.e., the wall) according to design requirements. After the decorative composite panel forms a mold, the space between the panel and the wall is filled with adhesive insulation material 114 that meets design requirements in batches according to the construction sequence. This mold-type construction method can:

[0090] (1) Reduce the number of exterior wall painting processes to lower project costs;

[0091] (2) The post-filling insulation method is simple, easy to construct, and easy to control the quality. It can also increase the adhesion between the insulation material and the wall and prevent hollowing, thus achieving better insulation and waterproofing effects.

[0092] The structural relationships and working principles of this utility model are as follows:

[0093] Standard Insulation and Decorative Composite Board 101:

[0094] Select a standard board-specific foamed ceramic panel 102 (or other lightweight, high-strength material panel conforming to specifications) of the required thickness as the panel for the standard board insulation and decorative composite panel 101, with dimensions as designed. Further, waterproof tongue and groove joints are provided around the panel, enabling the standard board insulation and decorative composite panel 101 to have self-waterproofing capabilities. Simultaneously, special assemblies with mortise and tenon joints are processed (including standard board connectors 104, upper and lower connecting tenons 106, support members 107, bolts 108, and first expansion bolts 109). Further, after the tongue and groove joints are completed, standard board connectors 104 are installed at the tension joint positions on the upper and lower edges of each panel according to design requirements. The standard board connectors 104 enlarge the stress-bearing surface between the mortise holes of the standard board connectors 104 and the panel when under stress. Furthermore, during installation, the tenons of the upper and lower connecting tenons 106 enter the mortises of the standard board connector 104. Under tension, the force is transferred to the standard board connector 104, and then to the standard board-specific foamed ceramic panel 102. Because the standard board connector 104 has a large contact area with the standard board-specific foamed ceramic panel 102, the panel is less prone to damage under tension, improving the connection strength between the connector and the panel. This solves the problem of conventional exterior wall insulation and decorative composite panel tie rods being directly grooved on the panel opening for tension, which easily damages the tension points on the panel, causing panel detachment and safety accidents. Furthermore, an insulation material layer 103 conforming to design requirements is bonded to the standard board-specific foamed ceramic panel 102. The insulation material layer 103 is edge-sealed with a 5mm thick mortar layer 105 around its perimeter (if the insulation material layer 103 uses a Class A insulation board, mortar edge sealing is not required). Furthermore, the panel surface is finished according to design requirements at the factory. Furthermore, on-site installation of the standard thermal insulation and decorative composite panel 101 is completed according to the design layout using adhesive mortar layer (agent) 110 and special components. During construction, the tenon and mortise joints and tongue and groove structure of the special components can ensure that the composite panel is installed more accurately and firmly, and can better prevent it from falling off.

[0095] Overall external corner insulation and decorative composite panel 111:

[0096] Similarly, a foamed ceramic panel 112 (or other lightweight, high-strength material panel meeting specifications) of the required thickness for integral external corner insulation is selected as the panel for the integral external corner external insulation decorative composite panel 111, with dimensions as designed. Further, a high-low tongue and groove joint is machined around the perimeter of the foamed ceramic panel 112 for integral external corner insulation, thereby enabling the integral external corner external insulation decorative composite panel 111 to have a self-waterproof function. Simultaneously, a special assembly with mortise and tenon joints (including a first external corner connector 113, upper and lower connecting tenons 106, a support 107, bolts 108, and a first expansion bolt 109) is machined. Further, the first external corner connector 113 is installed on the upper and lower edges of the corner panel to reinforce the panel body. Further, the special first external corner connector 113 is installed on the upper and lower edges for fixation as required. Furthermore, the insulation material layer 103, which meets the design requirements, is bonded and composited with the special foamed ceramic panel 112 for the overall external corner. The edges of the insulation material layer 103 are sealed with a 5mm thick mortar layer 105 (if the insulation material layer 103 uses a Class A insulation board, then mortar sealing is not required). Further, the panel surface is finished according to the design requirements at the factory. Further, on-site, the overall external corner external insulation decorative composite panel 111 is installed according to the design layout using an adhesive mortar layer 110 and special assemblies. During construction, the special structure of the overall external corner external insulation decorative composite panel 111 ensures more precise and secure installation, prevents detachment, and effectively prevents damage at the external corner.

[0097] Integral window frame insulation and decorative composite panel:

[0098] Similarly, select the following foamed ceramic panels with the required thickness for the window frame top: 116, 118, 120, 122 (or other lightweight, high-strength materials that meet the specifications) as the panels for the window frame top insulation and decorative composite panel 115, 117, 119, and 121, respectively. Furthermore, the perimeter of the foamed ceramic panels for the window frames in various parts is processed into a high-low tongue and groove joint, which enables the window frame insulation and decorative composite board to have a self-waterproof function. At the same time, special assemblies with mortise and tenon structures are processed (including standard plate connector 104, upper and lower connecting tenons 106, support 107, bolt 108, first expansion bolt 109, single-sided connecting tenon 123, second external corner connector 124, third external corner connector 125, inverted U-shaped fixing 126, second expansion bolt 127, expansion bolt tube 128, window frame connector 129, and fourth external corner connector 130). Furthermore, after the tongue and groove joint is completed, standard plate connectors 104 or window frame connectors 129 are installed at the tension joint positions of the special foamed ceramic panels for window frames in various parts (including special foamed ceramic panels 116 for the top of the window frame, special foamed ceramic panels 118 for the window frame and windowsill, special foamed ceramic panels 120 for the left window frame, and special foamed ceramic panels 122 for the top of the right window frame) according to the design requirements. The standard plate connectors 104 or window frame connectors 129 enlarge the force-bearing surface between the mortise holes of the standard plate connectors 104 or window frame connectors 129 and the plate when under stress, making it less likely to damage the plate when under tension. Furthermore, the insulation material layer 103, which meets the design requirements, is bonded and laminated with the special foamed ceramic panels for each part of the window frame (including the special foamed ceramic panel 116 for the top of the window frame, the special foamed ceramic panel 118 for the window frame and windowsill, the special foamed ceramic panel 120 for the left window frame, and the foamed ceramic panel 122 for the top of the right window frame). The insulation material layer 103 is edged with 5mm thick mortar 105 (if the insulation material layer 103 uses Class A insulation board, then mortar edge sealing is not required). Furthermore, the panel surface is finished according to the design requirements at the factory.Furthermore, on-site installation is carried out using an adhesive mortar layer 110 and special components (including standard plate connectors 104, upper and lower connecting tenons 106, support 107, bolts 108, first expansion bolts 109, single-sided connecting tenons 123, second external corner connectors 124, third external corner connectors 125, inverted U-shaped fixings 126, second expansion bolts 127, expansion bolt tubes 128, window frame connectors 129, and fourth external corner connectors 130) to install the window frame insulation and decorative composite panels (including the top window frame insulation and decorative composite panel 115, the window frame and windowsill insulation and decorative composite panel 117, the left window frame insulation and decorative composite panel 119, and the right window frame insulation and decorative composite panel 121) according to the design layout. During construction, the special structure of the window frame insulation and decorative composite panels ensures more precise and secure installation, effectively prevents damage around the window opening, and completely solves the problems of water seepage and thermal bridging around the window.

[0099] Mold-type construction method for thermal insulation and decorative composite panels (post-filling insulation method):

[0100] After completing the standard foamed ceramic panel 102 with tongue and groove joint and the foamed ceramic panel 112 for integral external corners, custom-made special assemblies with mortise and tenon joints are simultaneously processed (including standard panel connector 104, first external corner connector 113, upper and lower connecting tenons 106, support 107, bolts 108, and first expansion bolts 109). Further, the panel surface is finished according to design requirements at the factory. Without bonding the composite insulation material, the panels are transported to the construction site for installation. During installation, the space between the panel and the wall is left as required by the design for the insulation layer, and then filled with the fillable insulation material 114 or other suitable insulation materials (such as polyurethane foam, lightweight insulating mortar, etc.). This on-site filling of insulation material ensures better integration of the insulation material with the wall, and this mold-type construction method reduces the need for exterior wall painting, lowering project costs.
