Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to a decorative composite insulation integrated board. Background Technology

[0002] Decorative composite insulation integrated panels, also known as energy-saving insulation and decorative integrated panels, are made by prefabricating and layering a decorative layer, an adhesive layer, and an insulation board in a factory. These panels are suitable not only for exterior wall insulation and decoration of new buildings but also for energy-saving and decorative renovations of existing buildings.

[0003] However, most existing decorative composite insulation panels are attached to the building's exterior wall layer by layer and piece by piece using anchors and adhesive mortar after the main exterior wall construction is completed. Slight negligence during construction, or damage to the anchors, poses a risk of detachment, resulting in significant safety hazards. In windy weather, cases of decorative composite insulation panels detaching from high-rise buildings are common. To improve the connection strength between the composite panel and the main building wall, some integrated cast-in-place composite panels have emerged in recent years.

[0004] For example, invention patent CN105714961A discloses a cast-in-place, non-disassembly, prefabricated insulated external formwork component, an external wall structure, and a construction method. The external formwork component includes an outer layer of cement-based fine concrete, an insulation layer, and an inner layer of cement-based fine concrete. A steel mesh is pre-embedded within the outer layer of cement-based fine concrete, and several shear-resistant connectors are fastened to the steel mesh. This patented technology combines the insulation layer with the prefabricated formwork component, eliminating the need for secondary construction of the insulation layer and improving the thermal insulation performance of the building wall. However, the shear-resistant connectors in this patented technology are prefabricated on the inner wall of the external formwork component, making transportation difficult.

[0005] For example, utility model patent CN215564061U discloses a panel, adhesive layer, and insulation layer stacked sequentially from the outside in, as well as connecting sleeves and anchor rods. The adhesive layer is specifically formed by concrete casting. The root of the connecting sleeve is pre-embedded in the adhesive layer, and its end face is flush with the outer wall of the insulation layer. Multiple connecting sleeves are arranged at equal intervals. The anchor rod is horizontally positioned, with one end connected to the connecting sleeve. The protruding part of the anchor rod connects to the steel reinforcement skeleton of the outer wall structure, and the other end abuts against the built-in casting template of the wall. In this patented technical solution, the integrated insulation and decoration wall panel, as an outer template cast with concrete, is integrally cast with the wall, resulting in high connection strength and reducing the risk of detachment. However, although the anchor rod in this patented technical solution uses a threaded connection to the connecting sleeve, solving the transportation problem, it does not effectively position the exposed length, thus failing to effectively limit the distance between it and the inner template.

[0006] Therefore, it is necessary to develop a new type of decorative composite insulation integrated board to address the above-mentioned defects, which has become an urgent problem for those skilled in the art. Utility Model Content

[0007] The purpose of this utility model is to provide a decorative composite insulation integrated panel that can be cast integrally with the building exterior wall, has high structural strength, is not easy to fall off, and the connectors can accurately limit the thickness of the cast concrete wall.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] This utility model discloses a decorative composite insulation integrated panel, prefabricated in a factory, comprising an insulation board, a mortar layer, inlays, a steel mesh frame, a decorative layer, and connectors. The mortar layer overlaps and bonds the insulation board and the decorative layer together. The steel mesh frame is embedded in the mortar layer. Multiple inlays are evenly arranged within the insulation board. The connectors are threadedly connected to the ends of the inlays away from the decorative layer. The inlays are specifically made of plastic. One end of each connector is coaxially fitted with a threaded sleeve, which is threaded into the threaded central hole of the inlay. An annular limiting platform is provided on the outer wall of the threaded sleeve, and the limiting platform abuts against the end face of the inlay.

[0010] Furthermore, the main body of the connector is a threaded steel bar, the threaded sleeve is attached to one end of the threaded steel bar, and the other end of the threaded steel bar is coaxially attached to a heat insulation pad, which can abut against the inner wall of the inner template.

[0011] Furthermore, one end of the insert with the threaded central hole is inserted into the insulation board, and the other end of the insert is set as a spacer. The cross-sectional profile of one end of the spacer is larger than that of one end of the threaded central hole; the spacer defines the distance between the steel mesh frame and the insulation board.

[0012] Furthermore, the spacer head has multiple fan-shaped grooves evenly distributed around its outer circumference, and the fan-shaped grooves are filled with the mortar layer material.

[0013] Furthermore, a snap-fit ​​connector is provided at the top edge of the spacer head, which can snap the steel wires of the steel mesh frame.

[0014] Furthermore, the connector is L-shaped, and the root of the connector is integrally formed at the top edge of the spacer.

[0015] Furthermore, the insulation board is specifically made of any one of polystyrene foam insulation board, graphite polystyrene foam insulation board, extruded polystyrene board, or polyurethane insulation board.

[0016] Furthermore, the decorative layer is specifically made of ceramic tiles, stone, or decorative metal panels.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0018] This utility model discloses a decorative composite insulation integrated panel that simultaneously serves as the outer formwork for wall casting during on-site construction. It is integrally formed onto the outer wall, saving on the need for external formwork and subsequent exterior wall insulation and decoration work, thus reducing construction costs and time. Furthermore, the insulation panel boasts high connection strength and strong wind resistance. The use of plastic inserts improves thermal insulation performance and prevents thermal bridges at the joints. A limiting platform on the outer wall of the threaded sleeve precisely limits the exposed length of the connectors, ensuring uniform thickness of the cast concrete wall.

[0019] Furthermore, by installing plastic threaded sleeves and heat-insulating pads at both ends of the threaded steel bars, thermal bridging and heat transfer are reduced, while ensuring sufficient connection strength. Spacers at the outer ends of the inserts limit the distance between the steel mesh frame and the insulation board, ensuring the steel mesh frame is centrally positioned within the mortar layer for good crack resistance. Multiple fan-shaped grooves evenly distributed around the periphery of the spacers enhance the connection strength between the inserts and the mortar layer after curing, preventing the risk of later detachment or peeling of the insulation board and decorative layer. A snap-fit ​​connector at the top edge of the spacers secures the steel wires of the steel mesh frame, establishing a temporary connection and providing temporary fixation during prefabrication, preventing deformation and ensuring the prefabrication quality of the integrated panel.

[0026] The core of this utility model is to provide a decorative composite insulation integrated panel that can be cast integrally with the building exterior wall, has high structural strength, is not easy to fall off, and the connectors can accurately limit the thickness of the cast concrete wall.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In the following detailed description of the accompanying drawings, the descriptions of top, bottom, left, and right are all relative to the accompanying drawings and should not be construed as limiting the present utility model.

[0028] Refer to the attached diagram. Figure 1 This is a schematic diagram of the main sectional view of the decorative composite thermal insulation integrated panel of this utility model in its installation state; Figure 2 This is a schematic diagram of the main sectional view of the decorative composite thermal insulation integrated panel (excluding connectors) of this utility model; Figure 3 This is a three-dimensional structural diagram of the inlay component of this utility model; Figure 4 This is a schematic diagram of the main sectional view of the connector of this utility model.

[0029] In one specific implementation, such as Figures 1-4As shown, a decorative composite insulation integrated panel is prefabricated in a factory, transported to the construction site, and then cast into a single unit to form the exterior wall of the building after formwork erection. This utility model of a decorative composite insulation integrated panel includes an insulation board 1, a mortar layer 2, inlays 3, a steel mesh frame 4, a decorative layer 5, and connectors 6. The mortar layer 2 overlaps and bonds the insulation board 1 and the decorative layer 5 together. The mortar layer 2 contains adhesive-enhancing components, ensuring sufficient bonding strength between the insulation board 1 and the decorative layer 5 and preventing detachment. The steel mesh frame 4 is embedded within the mortar layer 2, improving the crack resistance of the mortar layer 2. Multiple inlays 3 are evenly arranged within the insulation board 1, and the connectors 6 are threaded to the end of the inlay 3 facing away from the decorative layer 5, meaning the connectors 6 are installed in a detachable manner. The key innovation of this decorative composite insulation integrated panel lies in the fact that the inlay 3 is specifically a plastic part, and one end of the connector 6 is coaxially fitted with a threaded sleeve 601, which is threadedly connected to the threaded central hole of the inlay 3. An annular limiting platform 602 is provided on the outer wall of the threaded sleeve 601, which abuts against the end face of the inlay 3, precisely limiting the exposed length of the connector 6.

[0030] This utility model uses a factory-prefabricated integrated insulation and decoration panel, which simultaneously serves as the outer formwork for wall casting during on-site construction. It is integrally formed on the outer wall, saving on the need for external formwork and subsequent exterior wall insulation and decoration work, thus reducing construction costs and time. Simultaneously, the insulation panel 1 has high connection strength and strong wind resistance. The use of plastic inserts 3 improves thermal insulation performance and avoids thermal bridging at the connectors 6. By setting a limiting platform 602 on the outer wall of the threaded sleeve 601, the exposed length of the connector 6 is precisely limited, thereby ensuring a uniform thickness of the cast concrete wall 7.

[0031] In one specific implementation of this embodiment, such as Figure 1 and Figure 4 As shown, the main body of connector 6 is a threaded steel bar, and a threaded sleeve 601 is attached to one end of the threaded steel bar. A heat-insulating pad 603 is coaxially attached to the other end of the threaded steel bar, and the heat-insulating pad 603 can abut against the inner wall of the inner template 8. Both the threaded sleeve 601 and the heat-insulating pad 603 are made of thermoplastic and are fixedly connected to both ends of the threaded steel bar using a thermal bonding method.

[0032] By setting plastic threaded sleeves 601 and heat insulation pads 603 at both ends of the threaded steel bar, the heat transfer through thermal bridging is reduced, while the connection strength is sufficiently guaranteed.

[0033] In one specific embodiment of this utility model, such as Figures 1-3As shown, one end of the insert 3 with the threaded central hole is inserted into the insulation board 1, and the other end of the insert 3 is set as a spacer head 301. The cross-sectional profile of one end of the spacer head 301 is larger than that of the end with the threaded central hole. The spacer head 301 defines the distance between the steel grid frame 4 and the insulation board 1.

[0034] Specifically, in the actual factory prefabrication process, the insulation board 1 is placed horizontally on the workbench at the bottom, the insert 3 is installed on the insulation board 1, and the steel mesh frame 4 is placed horizontally on the insulation board 1 and supported by multiple spacers 301. That is to say, the height of the spacers 301 limits the distance between the steel mesh frame 4 and the insulation board 1, which is generally controlled between 20 and 45 mm.

[0035] Specifically, such as Figure 2 and Figure 3 As shown, multiple fan-shaped grooves are evenly distributed around the outer circumference of the spacer head 301, and the fan-shaped grooves are filled with mortar layer 2 material.

[0036] In fact, the middle position of the spacer 301 is a cross-shaped support rib plate. The mortar layer 2 material used for bonding is filled into the fan-shaped groove to improve the connection strength between the insert 3 and the mortar layer 2 after curing, and there is no risk of them separating from each other.

[0037] By setting a spacer head 301 at the outer end of the inlay 3, the distance between the steel mesh frame 4 and the insulation board 1 is limited, so that the steel mesh frame 4 is centrally positioned in the mortar layer 2, achieving good crack resistance. By evenly distributing multiple fan-shaped grooves around the outer circumference of the spacer head 301, the connection strength between the inlay 3 and the mortar layer 2 after curing is improved, avoiding the risk of the insulation board 1 and the decorative layer 5 falling off and peeling off later.

[0038] In one specific embodiment of this utility model, such as Figures 1-3 As shown, a snap-fit ​​connector 302 is provided at the top edge of the spacer 301, which can snap the steel wires of the steel grid frame 4.

[0039] Specifically, such as Figure 3 As shown, the clamp connector 302 is L-shaped, and its base is integrally formed at the top edge of the spacer head 301. The horizontal arm at the top of the clamp connector 302 limits and clamps the steel wires of the steel grid frame 4.

[0040] In the actual factory prefabrication process of this utility model of decorative composite insulation integrated panel, the steel mesh frame 4 is placed flat on top of the insulation board 1 and supported by multiple spacers 301. At this time, the clamping joints 302 are not clamped to the steel wires but are located inside the wire mesh. The operator needs to manually rotate the insert 3 counterclockwise so that the horizontal arm at the top of the clamping joint 302 clamps the steel wires of the steel mesh frame 4 from the top surface, thus temporarily fixing the insert 3 and the steel mesh frame 4 and preventing the steel mesh frame 4 from shifting during the mortar layer 2 laying process.

[0041] By setting a snap-fit ​​connector 302 at the top edge of the spacer 301, the snap-fit ​​connector 302 snaps into the steel wire of the steel grid frame 4, establishing a temporary connection relationship, forming a temporary fixation during the prefabrication process, avoiding prefabrication deformation, and ensuring the prefabrication quality of the integrated panel.

[0042] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, insulation board 1 is specifically made of any one of polystyrene foam insulation board, graphite polystyrene foam insulation board, extruded polystyrene board, or polyurethane insulation board.

[0043] When using polystyrene foam insulation board or graphite polystyrene foam insulation board, the mounting holes for insert 3 can be machined by pre-embedding core pillars within the mold cavity. When using extruded polystyrene board, the mounting holes for insert 3 need to be completed by rotary cutting with a cutting tool.

[0044] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, decorative layer 5 is made of ceramic tiles, stone, or decorative metal panels. When using marble veneer, expansion joints between the stones must be properly designed to prevent large areas of stone from being squeezed and detached.

[0045] The factory prefabrication process of this utility model decorative composite insulation integrated panel is as follows: First, the installation holes for the inlay parts 3 are processed on the insulation board 1. The installation holes for the inlay parts 3 are arranged reasonably according to the design requirements, with a general requirement of no less than 8 holes per square meter. The insulation board 1 is placed horizontally on the workbench, and the inlay parts 3 are installed onto the insulation board 1. The steel mesh frame 4 is then placed horizontally on the insulation board 1 and supported by multiple spacers 301. The operator manually rotates the inlay parts 3 counterclockwise, causing the horizontal arm at the top of the clamping joint 302 to clamp the steel wires of the steel mesh frame 4, temporarily fixing the inlay parts 3 and the steel mesh frame 4 to prevent the steel mesh frame 4 from shifting during the mortar layer 2 laying process. The adhesive mortar for the mortar layer 2 is then laid, with baffles installed around the perimeter to prevent overflow. The decorative layer 5, with adhesive applied, is then laid flat on the mortar layer 2 to complete the bonding. After curing, the panel is removed and stored. It should be noted that connector 6 is not installed after prefabrication. It is installed when the formwork is erected on the construction site, which reduces the difficulty of transportation.

[0046] The decorative composite insulation integrated panel described in this case serves as the outer formwork for wall pouring during on-site construction. It is integrally formed on the outer wall, saving on external formwork and subsequent exterior wall insulation and decoration work, thus reducing construction costs and time. Simultaneously, the insulation panel 1 has high connection strength and strong wind resistance. The use of plastic inserts 3 improves thermal insulation performance and avoids thermal bridges at the connectors 6. A limiting platform 602 on the outer wall of the threaded sleeve 601 precisely limits the exposed length of the connector 6, ensuring uniform thickness of the poured concrete wall 7. Furthermore, the use of plastic threaded sleeves 601 and thermal insulation pads 603 at both ends of the threaded steel bar reduces heat transfer through thermal bridges while ensuring sufficient connection strength. A spacer 301 at the outer end of the insert 3 limits the distance between the steel mesh frame 4 and the insulation panel 1, ensuring the steel mesh frame 4 is centrally positioned within the mortar layer 2 for good crack resistance. By evenly distributing multiple fan-shaped grooves around the periphery of the spacer head 301, the connection strength between the inlay 3 and the mortar layer 2 after curing is improved, avoiding the risk of the insulation board 1 and the decorative layer 5 falling off later. A snap-fit ​​connector 302 is provided at the top edge of the spacer head 301, which snaps onto the steel wire of the steel mesh frame 4, establishing a temporary connection and forming temporary fixation during the prefabrication process. This prevents prefabrication deformation and ensures the prefabrication quality of the integrated panel.

[0047] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
