Description

Technical Field

[0001] This invention relates to the field of thermal insulation decorative panel technology, specifically to an anchoring foundation structure for thermal insulation decorative panels based on a single horizontal keel. Background Technology

[0002] In the field of building exterior wall insulation and decoration, the installation process of insulation decorative panels is crucial. Traditional installation methods for insulation decorative panels have many problems, affecting construction efficiency and installation quality. Traditional installation methods often involve complex structural components requiring extensive on-site welding and drilling, demanding high technical skills from construction workers. This is especially problematic when workers are at heights and unable to coordinate with others, leading to cumbersome installation steps, low efficiency, and extended construction periods. Regarding installation stability, some methods rely on single fixing methods, such as adhesive bonding or simple mechanical connections. Over long-term use, these methods are susceptible to loosening and detachment due to wind, vibration, and other external forces. Therefore, we have introduced an anchoring foundation structure for insulation decorative panels based on a single horizontal keel. Summary of the Invention

[0003] The purpose of this invention is to provide an anchoring foundation structure for thermal insulation decorative panels based on a single horizontal keel, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an anchoring base structure for a thermal insulation decorative panel based on a single horizontal keel, comprising a horizontal keel installed on the wall using an anchoring assembly, wherein the anchoring assembly includes a connecting seat assembly for fixing the horizontal keel to the wall and an anchoring locking member for fixing the positioning buckle at the connection between the horizontal keel and the connecting seat assembly.

[0005] The anchor locking component includes a U-shaped buckle seat, a locking and fixing component provided on the U-shaped buckle seat, and buckle hook-fitting components provided on both sides of the U-shaped buckle seat. The buckle hook-fitting components are used to buckle and fix with the thermal insulation decorative panel.

[0006] After the locking bolts on the locking fastener are tightened, the locking fastener moves relative to the U-shaped buckle seat, thereby fixing the U-shaped buckle seat to the horizontal keel and the connecting seat assembly. At the same time, the front end of the locking fastener abuts against the buckle hook and rotates open to fix the heat insulation decorative panel.

[0007] Preferably, the connecting seat assembly includes a connecting plate fixed in a reserved groove on the wall with expansion nails, connecting ears symmetrically fixed at the outer ends of the connecting plate, and vertical bolts for fixing the horizontal keel between the upper and lower connecting ears;

[0008] The connecting lug is provided with an oblong hole for the vertical bolt to pass through, and the vertical bolt is screwed and fixed to the horizontal keel.

[0009] Preferably, the four corners of the rear end of the U-shaped buckle seat are provided with buckle protrusions, the horizontal keel is locked between the upper and lower buckle protrusions, and the inner side of the buckle protrusion is provided with a right-angled groove for locking onto the connecting ear.

[0010] Preferably, the locking fastener includes an X-shaped frame located in front of the U-shaped buckle seat, tension rods provided at the four corners of the rear end of the X-shaped frame, and pins connecting the upper and lower tension rods. The tension rods extend through the positioning holes on the buckle protrusions, and the pins are located at the rear of the horizontal keel.

[0011] The rear center of the X-shaped frame is provided with a hexagonal groove for engaging the locking nut. The locking bolt is screwed to the locking nut, and the rear end of the locking bolt abuts against the front surface of the U-shaped buckle seat.

[0012] Preferably, the front of both sides of the U-shaped buckle seat is provided with grooves;

[0013] The buckle connector includes a gear movably connected to the groove by a pin, a support arm fixed to the front of the gear, and a buckle plate fixed to one side of the end of the support arm.

[0014] Preferably, the thermal insulation decorative panel includes a decorative panel and a thermal insulation board at the rear end of the decorative panel, and the snap-on plate is used to snap into the V-shaped groove at the connection between the decorative panel and the thermal insulation board.

[0015] Preferably, the end surface of the support arm is provided with an abutting plane, which is used to abut against the end face of the insulation board.

[0016] Preferably, the upper and lower sets of gears in the same groove mesh with each other, the X-shaped frame is provided with support plates on both sides, the end of the support plate is provided with a trapezoidal abutment block, the front surface of the support arm is provided with a slot for sliding the trapezoidal abutment block, and the front wall of the slot is provided with an inclined surface.

[0017] Compared with existing technologies, the advantages of this invention are as follows: The anchor structure of this invention adopts a modular design. On-site, only vertical bolts are needed to quickly clamp the horizontal keel between the connecting ears. The U-shaped buckle seat can quickly snap into the connection between the horizontal keel and the connecting ear through the right-angle buckle protrusion, achieving rapid positioning. One person can directly use an electric sleeve to tighten the locking bolts, which can not only fix the anchor assembly to the horizontal keel, but also achieve the buckle fixation of the insulation decorative panel. The operation is simple and easy to understand, and easy to install. The engagement of the right-angle buckle with the connecting ear provides shear support, while the locking bolt forms axial tension through the X-shaped frame and the tension rod, achieving "clamping + tension" double locking. Compared with traditional hangers, the overall wind load resistance is significantly improved, which can effectively resist external forces such as wind and vibration, ensuring that the insulation decorative panel is stable and does not loosen or fall off in the long term.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example:

[0048] Please see Figure 1-21 The present invention provides a technical solution:

[0049] An anchoring base structure for an insulated decorative panel based on a single horizontal keel includes a horizontal keel 2 installed on a wall 1 using an anchoring assembly 3, with adjacent horizontal keels 2 spaced at equal intervals. The horizontal keel 2 is horizontally positioned to the ground and has threaded holes for screwing into vertical bolts 3014.

[0050] Traditionally, installing exterior wall insulation panels requires fixing a frame consisting of longitudinal and transverse joists to the wall surface, and then hanging and fixing the insulation panels onto the frame. This makes the overall frame structure more complex, consumes more materials, and is time-consuming. This invention only requires installing horizontal joists 2 evenly spaced vertically on the wall 1, which then enables stable installation of the insulation panels, saving materials and shortening the construction period.

[0051] Anchor assembly 3 includes a connecting seat assembly 301 for fixing the horizontal keel 2 to the wall 1 and an anchor locking member 302 for fixing the positioning buckle at the connection between the horizontal keel 2 and the connecting seat assembly 301.

[0052] The anchor locking component 302 includes a U-shaped buckle seat 3021, a locking and fixing component provided on the U-shaped buckle seat 3021, and buckle hooks provided on both sides of the U-shaped buckle seat 3021. The buckle hooks are used to buckle and fix the heat insulation decorative panel.

[0053] The anchor assembly 3 (connector assembly 301 and anchor locking component 302) can be pre-assembled in the factory. On-site, the connecting plate 3011 only needs to be fixed to the reserved groove 101 of the wall 1 by expansion nails 3012, avoiding traditional on-site welding or complicated adjustments, thus improving installation efficiency.

[0054] The horizontal keel 2 is quickly clamped between the connecting ears 3013 by the vertical bolts 3014. No additional positioning tools are required, and a single person can complete the initial fixation of the horizontal keel.

[0055] The connector assembly 301 includes a connector plate 3011 fixed in a pre-reserved groove 101 on the wall 1 by expansion nails 3012, connector ears 3013 symmetrically fixed at the outer ends of the connector plate 3011, and vertical bolts 3014 fixing the horizontal keel 2 between the upper and lower connector ears 3013.

[0056] The expansion nail 3012 is made of nylon and features a serrated surface design to enhance friction with the pre-drilled groove 101. It is suitable for various wall substrates such as concrete and aerated concrete blocks, and has a pull-out strength ≥8kN (tested according to JGJ144-2019 standard).

[0057] The connecting plate 3011 has a thickness of ≥4mm and can be stamped with reinforcing ribs to improve its bending resistance. When the span of the horizontal keel is ≤1.2m, the deformation of the connecting plate 3011 is ≤0.3mm.

[0058] The connecting lug 3013 has an oblong hole 3015 for the vertical bolt 3014 to pass through, and the vertical bolt 3014 is screwed and fixed to the horizontal keel 2. The oblong hole 3015 of the connecting lug 3013 allows the horizontal keel 2 to be adjusted horizontally within a range of ±5mm, which can accommodate the flatness error of the wall surface, reduce the amount of on-site cutting work, and improve installation efficiency.

[0059] The four corners of the U-shaped buckle seat 3021 are provided with buckle protrusions 3022. The horizontal keel 2 is locked between the upper and lower buckle protrusions 3022. Rubber anti-slip strips are added to the inner side of the buckle protrusions 3022. When in contact with the horizontal keel 2, they produce elastic deformation, further eliminating the installation gap and improving the vibration resistance (displacement ≤0.5mm under simulated earthquake conditions).

[0060] The inner side of the buckle protrusion 3022 is provided with a right-angle slot 3033 for locking onto the connecting ear 3013.

[0061] The initial engagement of the right-angle slot 3033 and the connecting ear 3013 provides shear support, and the locking bolt 3028 forms axial tension through the X-shaped frame 3025 and the tension rod 3024 to achieve dual locking of "clamping + tensioning", thereby improving the wind load resistance.

[0062] The U-shaped buckle seat 3021 can be quickly snapped into the connection between the horizontal keel 2 and the connecting ear 3013 through the right-angle slot 3033 of the buckle protrusion 3022, forming a "plug and position" effect without the need for repeated position calibration.

[0063] The locking fastener includes an X-shaped frame 3025 located in front of the U-shaped buckle seat 3021, tension rods 3024 located at the four corners of the rear end of the X-shaped frame 3025, and pins 3023 connecting the upper and lower tension rods 3024. The rear end of the tension rod 3024 is provided with a reserved hole 3040 for penetrating the pin 3023. The tension rod 3024 extends through the positioning hole 3032 on the buckle protrusion 3022. The pin 3023 is located at the rear of the horizontal keel 2.

[0064] The rear center of the X-shaped bracket 3025 is provided with a hexagonal groove 3041 for engaging the locking nut 3029. The locking nut 3029 and the hexagonal groove 3041 are interference-fitted, and anti-rotation bosses are provided on the edge to prevent the nut from loosening due to long-term vibration and to ensure long-term stability of the locking state.

[0065] The locking bolt 3028 is screwed to the locking nut 3029, and the rear end of the locking bolt 3028 abuts against the front end surface of the U-shaped buckle seat 3021.

[0066] The front sides of the U-shaped buckle seat 3021 are provided with grooves 3031;

[0067] The snap-on connector includes a gear 3035 movably connected to a groove 3031 by a pin 3030, a support arm 3026 fixed at the front of the gear 3035, and a snap-on plate 3027 fixed to one side of the end of the support arm 3026.

[0068] The upper and lower walls at the end of the slot 3036 are provided with limiting bosses to limit the maximum rotation angle of the support arm 3026 to 45°, preventing the buckle plate 3027 from opening excessively and damaging the insulation decorative panel, while ensuring that the depth of the V-shaped groove 501 is ≥15mm.

[0069] The V-groove 501 has an angle of 60°±2°, and the groove width matches the thickness of the 3027 snap-fit ​​plate (tolerance ±0.1mm) to ensure a tight wedge fit when snapped in, with a pull-out force ≥600N / m (tested according to JGJ110-2017 standard).

[0070] The thermal insulation decorative panel includes a decorative panel 4 and an insulation board 5 at the rear end of the decorative panel 4. A snap-on plate 3027 is used to snap into the V-groove 501 at the connection between the decorative panel 4 and the insulation board 5.

[0071] The area of ​​the decorative panel 4 is larger than that of the insulation board 5. After the insulation and decorative panel is installed, the decorative panel 4 can cover the anchor assembly 3. The gap between the upper and lower adjacent insulation and decorative panels is large enough for the electric sleeve to be inserted to tighten or loosen the locking bolt 3028. Furthermore, sealing strips will be installed between the adjacent insulation and decorative panels for sealing.

[0072] The end surface of the support arm 3026 is provided with an abutment plane 3034, which is used to abut against the end face of the insulation board 5. An EVA buffer strip with a thickness of 2mm and a compression hardness of 40 Shore A is attached to the abutment plane 3034, which can absorb the stress generated by the thermal expansion and contraction of the insulation board 5 and reduce the risk of interface cracking.

[0073] The abutting surface 3034 of the support arm 3026 transmits the snapping force to the entire insulation board 5, preventing the V-groove 501 from cracking due to local stress.

[0074] When installing the thermal insulation decorative panel, simply place the panel on the abutting plane 3034 of the support arm 3026. There is no need to precisely align the V-groove 501. The synchronous drive of the locking bolt 3028 will automatically cause the buckle plate 3027 to snap into the groove, achieving quick installation with "one placement and two tightening".

[0075] Two sets of gears 3035 in the same groove 3031 mesh with each other. Support plates 3038 are provided on both sides of the X-shaped frame 3025. Trapezoidal abutment blocks 3039 are provided at the ends of the support plates 3038. The front surface of the support arm 3026 is provided with a slot 3036 for sliding the trapezoidal abutment blocks 3039. The front wall of the slot 3036 is provided with an inclined surface 3037.

[0076] When the locking bolt 3028 is tightened, the X-shaped frame 3025 drives the support plate 3038 to move forward, causing the trapezoidal abutment block 3039 to move forward along the slot 3036 until the trapezoidal abutment block 3039 slides onto the inclined surface 3037, causing the trapezoidal abutment block 3039 to push the support arm 3026 to rotate and open around the pin 3030.

[0077] The slotted 3036 with its inclined surface 3037 guides the trapezoidal abutment block 3039 to progressively push the support arm 3026, reducing impact loads.

[0078] After the locking bolt 3028 on the locking fastener is tightened, the locking fastener moves relative to the U-shaped buckle seat 3021, thereby achieving the positioning and buckling fixation of the U-shaped buckle seat 3021 at the connection between the horizontal keel 2 and the connecting seat assembly 301. At the same time, the front end of the locking fastener abuts against the buckle hook and rotates open to achieve the buckling fixation of the thermal insulation decorative panel.

[0079] Specifically, when using it:

[0080] 1. Basic Connections and Positioning:

[0081] Horizontal keel fixing: The connecting plate 3011 is fixed to the reserved groove 101 in the wall 1 by expansion nails 3012. The upper and lower symmetrical connecting ears 3013 clamp and fix the horizontal keel 2 by vertical bolts 3014. The oval hole 3015 of the connecting ear 3013 allows the vertical bolt 3014 to move slightly, realizing fine adjustment of the position of the horizontal keel 2 during installation, ensuring that the horizontal keel 2 is perpendicular and flat to the wall surface.

[0082] Anchor locking component positioning: The U-shaped buckle seat 3021 engages with the connection between the horizontal keel 2 and the connecting ear 3013 through the right-angle groove 3033 of the rear buckle protrusion 3022, forming an initial positioning. At this time, the horizontal keel 2 is clamped between the upper and lower buckle protrusions 3022, and the right-angle groove 3033 engages with the edge of the connecting ear 3013 to prevent the U-shaped buckle seat 3021 from shifting laterally.

[0083] Then, the insulation decorative panel is placed on the abutting plane 3034 at the upper end of the support arm 3026 of the corresponding buckle hook, so that the buckle plate 3027 is snapped into the V-shaped groove 501 at the bottom of the insulation decorative panel.

[0084] 2. Driving mechanism of locking fasteners:

[0085] The locking bolt linkage: Rotate the locking bolt 3028 to screw it into the locking nut 3029 and push it back against the front end of the U-shaped buckle seat 3021. As the locking bolt 3028 is tightened, the X-shaped bracket 3025 drives the tension rod 3024 to move forward (the tension rod 3024 moves forward along the positioning hole 3032 of the buckle protrusion 3022), while the pin 3023 presses against the rear of the horizontal keel 2, forming a reverse tension force.

[0086] Positioning and buckling are achieved simultaneously: When the X-shaped frame 3025 moves forward relative to the U-shaped buckle seat 3021, on the one hand, the tension rod 3024 drives the U-shaped buckle seat 3021 to further clamp the horizontal keel 2 and the connecting ear 3013, and the rigid engagement of the right-angle slot 3033 achieves mechanical locking; on the other hand, the trapezoidal abutment blocks 3039 on both sides of the X-shaped frame 3025 push the support arm 3026 to rotate around the pin 3030, so that the buckle plate 3027 at the bottom of the heat insulation decorative panel opens outward until the abutment plane 3034 is in a horizontal position.

[0087] Then the locking bolts 3028 on the top of the insulation decorative panel are also tightened, causing the support arm 3026 on the top of the insulation decorative panel to rotate and open until the buckle plate 3027 at the end of the support arm 3026 on the top of the insulation decorative panel is engaged into the V-shaped groove 501 on the top of the insulation decorative panel. In this way, the support arms 3026 on the top and bottom of the insulation decorative panel clamp and fix the insulation decorative panel, thus fixing the insulation decorative panel from the top and bottom direction.

[0088] Symmetrical buckle design: The upper and lower gears 3035 synchronously drive the buckle plate 3027, avoiding the eccentric force problem of traditional single-sided buckles. The flatness error of the insulation decorative panel after installation is ≤1.5mm, which is better than the industry standard (GB / T29906-2013).

[0089] 3. Working logic of the snap-on connector:

[0090] Synchronization of gear meshing: The upper and lower gears 3035 in the same groove 3031 mesh with each other. When the trapezoidal abutment block 3039 pushes the lower support arm 3026 to rotate, the upper support arm 3026 is driven to rotate synchronously in the opposite direction through the gear 3035, ensuring that the upper and lower buckle plates 3027 open symmetrically and are evenly inserted into both sides of the V-shaped groove 501, avoiding the decorative panel from tilting due to unilateral force.

[0091] The stabilizing effect of the abutting plane: The abutting plane 3034 at the end of the support arm 3026 is in close contact with the end face of the insulation board 5, forming a mechanical limit to prevent the buckle plate 3027 from being over-inserted and damaging the decorative panel. At the same time, the surface contact disperses stress and improves the reliability of the connection.

[0092] The engagement of the right-angle slot 3033 and the connecting ear 3013 provides shear support (measured shear bearing capacity ≥12kN). The locking bolt 3028 applies axial tension through the X-shaped frame 3025 and the tension rod 3024, forming a double locking of "clamping + tension". The overall wind load resistance is 40% higher than that of traditional hangers (refer to GB50009-2012 wind load calculation).

[0093] 4. Disassembly and adjustment:

[0094] Loosen the locking bolt 3028, and the X-shaped bracket 3025 moves forward under the reverse pulling force. The trapezoidal abutment block 3039 disengages from the inclined surface 3037 of the groove 3036, and the support arm 3026 retracts synchronously under the meshing action of the gear 3035. The buckle plate 3027 disengages from the V-shaped groove 501. At this time, the thermal insulation decorative panel can be easily removed, or the position of the horizontal keel 2 can be adjusted through the oval hole 3015 to achieve quick maintenance or secondary installation.

[0095] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
