Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation decorative panels, in particular to an anchoring foundation structure of thermal insulation decorative panels based on a single transverse keel. Background Art

[0002] In the field of building exterior wall insulation and decoration, the installation process of insulation decorative panels is of vital importance. Traditional installation methods of insulation decorative panels have many problems that affect construction efficiency and installation quality. In traditional installation methods of insulation decorative panels, some installation structures are complex and require a large amount of on-site welding, punching and other operations, which places high technical requirements on construction workers. Especially when construction workers are at high altitudes and cannot cooperate with others for installation, the installation steps are cumbersome, resulting in low construction efficiency and extended construction period. In terms of installation stability, some installation methods use a single fixing method, such as relying solely on bonding or simple mechanical connections. During long-term use, they are prone to loosening and falling off due to external forces such as wind and vibration. For this reason, we have introduced an anchoring foundation structure for insulation decorative panels based on a single horizontal keel. Summary of the Invention

[0003] The object of the present invention is to provide an anchoring foundation structure for thermal insulation decorative panels based on a single transverse keel, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solutions: an anchoring foundation structure for a thermal insulation decorative panel based on a single transverse keel, comprising a transverse keel mounted on a wall using an anchoring assembly, the anchoring assembly comprising a connecting seat assembly for fixing the transverse keel to the wall, and an anchoring locking member with a positioning clip fixed to the connection between the transverse keel and the connecting seat assembly; The anchor locking member includes a U-shaped snap seat, a locking fixing member provided on the U-shaped snap seat, and snap hanging members provided on both sides of the U-shaped snap seat, and the snap hanging members are used to snap and fix with the thermal insulation decorative panel; After the locking bolt on the locking fixing piece is tightened, the locking fixing piece moves relative to the U-shaped snap seat, thereby realizing the positioning snap fixation of the connection between the U-shaped snap seat and the cross keel and the connecting seat assembly. At the same time, the front end of the locking fixing piece abuts against the snap hanging piece and rotates and opens to realize the snap fixation of the thermal insulation decorative panel.

[0005] Preferably, the connecting seat assembly includes a connecting plate fixed in a reserved groove on the wall by using expansion nails, connecting ears fixed symmetrically up and down the outer ends of the connecting plate, and a vertical bolt fixing the transverse keel between the upper and lower connecting ears; The connecting ears are provided with waist-round holes for passing vertical bolts, and the vertical bolts are screwed and fixed to the transverse keels.

[0006] Preferably, snap protrusions are provided at the four corners of the rear end of the U-shaped snap seat, the transverse keel is clamped between the upper and lower snap protrusions, and a right-angled groove for clamping on the connecting ear is provided on the inner side of the snap protrusion.

[0007] Preferably, the locking fixture 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 a pin connecting the upper and lower tension rods, the tension rods extending through the positioning holes on the buckle protrusions, and the pins located at the rear of the transverse keel; A hexagonal groove for clamping a locking nut is provided in the middle of the rear end of the X-shaped frame. The locking bolt is threadedly connected to the locking nut, and the rear end of the locking bolt abuts against the front end surface of the U-shaped buckle seat.

[0008] Preferably, grooves are provided on the front of both sides of the U-shaped buckle seat; The buckle hanging part includes a gear movably connected to the groove by a pin shaft, a support arm fixed at the front of the gear, and a buckle plate fixed at one side of the end of the support arm.

[0009] Preferably, the thermal insulation decorative plate includes a decorative panel and a thermal insulation plate at the rear end of the decorative panel, and the snap plate is used to snap into a V-shaped groove at the connection between the decorative panel and the thermal insulation plate.

[0010] Preferably, the end surface of the support arm is provided with a resting plane, and the resting plane is used to rest against the end surface of the insulation board.

[0011] Preferably, the upper and lower sets of gears in the same groove are meshed with each other, support plates are provided on both sides of the X-shaped frame, trapezoidal abutment blocks are provided at the ends of the support plates, and slots are provided on the front surfaces of the support arms for slidingly engaging the trapezoidal abutment blocks, and the front walls of the slots are provided with inclined surfaces.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: the anchoring structure of the present invention adopts a modular design. On site, it is only necessary to use vertical bolts to quickly clamp the transverse keel between the connecting ears. The U-shaped snap seat can be quickly inserted into the connection between the transverse keel and the connecting ear through the right-angled snap groove of the snap projection to achieve rapid positioning. One person directly uses an electric sleeve to lock the locking bolt, which can not only complete the fixation of the anchoring assembly and the transverse keel, but also achieve the snap fixation of the thermal insulation decorative panel.

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example: See also Figure 1-21 , the present invention provides a technical solution: A single-transverse keel anchoring foundation structure for thermal insulation decorative panels includes a transverse keel 2 mounted on a wall 1 using an anchoring assembly 3. Upper and lower adjacent transverse keels 2 are spaced evenly apart. The transverse keels 2 are positioned horizontally with the ground and have threaded holes for threaded engagement with vertical bolts 3014.

[0017] When installing traditional building exterior wall insulation decorative panels, it is necessary to fix a frame consisting of longitudinal and transverse keels on the wall, and then hang the insulation decorative panels on the frame. This makes the overall frame structure more complex, consumes more materials, and is time-consuming to install. The present invention only requires installing transverse keels 2 with equal spacing on the wall 1, and then the insulation decorative panels can be stably installed, saving materials and shortening the construction period.

[0018] The anchor assembly 3 includes a connecting seat assembly 301 for fixing the transverse keel 2 to the wall 1 and an anchor locking member 302 fixed at the connection between the transverse keel 2 and the connecting seat assembly 301 with a positioning buckle; The anchor locking member 302 includes a U-shaped snap seat 3021, a locking fixture provided on the U-shaped snap seat 3021, and snap-on hanging members provided on both sides of the U-shaped snap seat 3021. The snap-on hanging members are used to snap-on and fix with the thermal insulation decorative panel. The anchor assembly 3 (connecting seat assembly 301 and anchor locking member 302) can be pre-assembled in the factory. On-site, it is only necessary to fix the connecting plate 3011 to the reserved groove 101 of the wall 1 using expansion nails 3012, avoiding traditional on-site welding or complex adjustments, thereby improving installation efficiency.

[0019] The transverse keel 2 is quickly clamped between the connecting ears 3013 by vertical bolts 3014. No additional positioning tools are required, and a single person can complete the initial fixation of the transverse keel.

[0020] The connecting seat assembly 301 includes a connecting plate 3011 fixed in a reserved groove 101 on the wall 1 using expansion nails 3012, connecting ears 3013 symmetrically fixed to the outer ends of the connecting plate 3011, and vertical bolts 3014 that fix the transverse keel 2 between the upper and lower connecting ears 3013. Expansion nail 3012 is made of nylon, and the serrated surface design enhances the friction with the reserved groove 101. It is suitable for various wall substrates such as concrete and aerated blocks, and has a tensile strength of ≥8kN (tested according to JGJ144-2019 standard).

[0021] The thickness of the connecting plate 3011 is ≥4mm, and reinforcement ribs can be stamped on the surface to improve the bending resistance. When the span of the transverse keel 2 is ≤1.2m, the deformation of the connecting plate 3011 is ≤0.3mm.

[0022] The connecting lugs 3013 are provided with round holes 3015 for inserting vertical bolts 3014, which are screwed to the horizontal keel 2. The round holes 3015 in the connecting lugs 3013 allow the horizontal keel 2 to be adjusted within a range of ±5mm to accommodate wall flatness errors, reducing on-site cutting workload and improving installation efficiency.

[0023] Snap protrusions 3022 are provided at the four corners at the rear end of the U-shaped snap seat 3021. The transverse keel 2 is clamped between the upper and lower snap protrusions 3022. A rubber anti-slip strip is added to the inner side of the snap protrusion 3022, which produces elastic deformation when in contact with the transverse keel 2, further eliminating the installation gap and improving the anti-vibration performance (displacement ≤0.5mm under simulated earthquake conditions).

[0024] A right-angled slot 3033 for latching onto the connecting ear 3013 is provided on the inner side of the latch protrusion 3022 .

[0025] 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 tensioning rod 3024, achieving "snapping + tensioning" double locking, thereby improving the wind load resistance.

[0026] The U-shaped snap seat 3021 can be quickly inserted into the connection between the transverse keel 2 and the connecting ear 3013 through the right-angle snap groove 3033 of the snap protrusion 3022, forming a "plug and position" effect without the need for repeated position calibration.

[0027] The locking fixture includes an X-shaped frame 3025 located in front of the U-shaped buckle seat 3021, tension rods 3024 provided at the four corners of the rear end of the X-shaped frame 3025, and a pin 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 the pin 3023 to pass through. 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 transverse keel 2. A hexagonal slot 3041 for clamping the locking nut 3029 is provided in the middle of the rear end of the X-shaped frame 3025. The locking nut 3029 and the hexagonal slot 3041 adopt an interference fit, and an anti-rotation boss is provided on the edge to prevent the nut from loosening due to long-term vibration, thereby ensuring that the locking state is stable for a long time.

[0028] The locking bolt 3028 is threadedly connected 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 .

[0029] The front portions of both sides of the U-shaped buckle seat 3021 are provided with grooves 3031; The buckle hanging part includes a gear 3035 movably connected to the groove 3031 by a pin shaft 3030, a support arm 3026 fixed to the front of the gear 3035, and a buckle plate 3027 fixed to one side of the end of the support arm 3026.

[0030] 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 snap plate 3027 from excessively opening and damaging the insulation decorative panel, while ensuring that the depth of the V-groove 501 is ≥15mm.

[0031] The angle of the V-groove 501 is designed to be 60°±2°, and the groove width matches the thickness of the snap plate 3027 (tolerance ±0.1mm), ensuring a tight wedge fit during connection and a pull-out force ≥600N / m (tested according to JGJ110-2017 standard).

[0032] The heat-insulating decorative plate includes a decorative panel 4 and a heat-insulating plate 5 at the rear end of the decorative panel 4 . The snap plate 3027 is used to snap into the V-shaped groove 501 at the connection between the decorative panel 4 and the heat-insulating plate 5 .

[0033] The area of ​​the decorative panel 4 is larger than that of the insulation board 5. In this way, after the insulation decorative panel is installed, the decorative panel 4 can block the anchor assembly 3. The gap between the upper and lower adjacent insulation decorative panels is large enough for the electric sleeve to be inserted to lock or loosen the locking bolt 3028, and sealing strips will be installed between the adjacent insulation decorative panels for sealing.

[0034] The end surface of the support arm 3026 is provided with a support surface 3034, which is used to abut against the end surface of the insulation board 5. The support surface 3034 is affixed with an EVA cushioning strip with a thickness of 2mm and a compression hardness of 40ShoreA, which can absorb the stress caused by the thermal expansion and contraction of the insulation board 5 and reduce the risk of interface cracking.

[0035] The abutting plane 3034 of the support arm 3026 transmits the snapping force to the entire insulation board 5, thereby preventing the V-shaped groove 501 from being locally cracked due to stress.

[0036] When installing the thermal insulation decorative panel, you only need to place the panel on the abutting surface 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 snap the snap plate 3027 into the groove, realizing a quick installation of "one release and two twists".

[0037] The upper and lower sets of gears 3035 in the same groove 3031 are meshed 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. A slot 3036 for slidingly engaging the trapezoidal abutment blocks 3039 is provided on the front surface of the support arm 3026. A slope 3037 is provided on the front wall of the slot 3036.

[0038] 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, so that the trapezoidal abutment block 3039 pushes the support arm 3026 to rotate and open around the pin shaft 3030.

[0039] The inclined surface 3037 of the slot 3036 guides the trapezoidal abutment block 3039 to gradually push the support arm 3026, thereby reducing the impact load.

[0040] After the locking bolt 3028 on the locking fixture is tightened, the locking fixture moves relative to the U-shaped snap seat 3021, realizing the positioning snap fixation of the connection between the U-shaped snap seat 3021 and the cross keel 2 and the connecting seat assembly 301. At the same time, the front end of the locking fixture is pressed against the snap hanging piece and rotated to open, realizing the snap fixation of the thermal insulation decorative panel.

[0041] Specifically, when using: 1. Basic connection and positioning: Securing the Horizontal Baluster: The connecting plate 3011 is secured to the reserved slot 101 of the wall 1 using expansion screws 3012. Symmetrical connecting lugs 3013, located vertically, clamp the horizontal baluster 2 in place using vertical bolts 3014. Round holes 3015 in the connecting lugs 3013 allow for slight movement of the vertical bolts 3014, enabling fine-tuning of the horizontal baluster 2 during installation and ensuring its perpendicularity and alignment with the wall.

[0042] Anchor Locking Fixture Positioning: The U-shaped snap seat 3021 engages the connection between the transverse keel 2 and the connecting lug 3013 through the right-angled slot 3033 of the rear-end snap projection 3022, achieving initial positioning. At this point, the transverse keel 2 is clamped between the upper and lower snap projections 3022, and the right-angled slot 3033 engages the edge of the connecting lug 3013, preventing the U-shaped snap seat 3021 from shifting laterally.

[0043] Then place the thermal insulation decorative plate on the abutting plane 3034 at the upper end of the support arm 3026 of the corresponding snap-on hanging member, so that the snap-on plate 3027 is snapped into the V-shaped groove 501 at the bottom of the thermal insulation decorative plate.

[0044] 2. The driving mechanism of the locking fixture: Locking bolt linkage: Rotate locking bolt 3028, threading it into locking nut 3029 and pressing it backward against the front end of U-shaped snap seat 3021. As locking bolt 3028 is tightened, X-shaped bracket 3025 drives tension rod 3024 forward (tension rod 3024 moves forward along positioning hole 3032 of snap protrusion 3022), while pin 3023 presses against the rear of cross keel 2, generating reverse tension.

[0045] Positioning and snapping are achieved simultaneously: when the X-shaped frame 3025 moves forward relative to the U-shaped snap seat 3021, on the one hand, the tensioning rod 3024 drives the U-shaped snap seat 3021 to further clamp the transverse keel 2 and the connecting ear 3013, and mechanical locking is achieved by the rigid engagement of the right-angle slot 3033; 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 shaft 3030, so that the snap plate 3027 at the bottom of the thermal insulation decorative panel opens outward until the abutment plane 3034 is in a horizontal position.

[0046] Then the locking bolt 3028 above the thermal insulation decorative panel is also tightened, so that the support arm 3026 above the thermal insulation decorative panel also rotates and opens, and until the snap plate 3027 at the end of the support arm 3026 above the thermal insulation decorative panel is snapped into the V-shaped groove 501 at the top of the thermal insulation decorative panel, so that the support arms 3026 above and below the thermal insulation decorative panel clamp and fix the thermal insulation decorative panel from the upper and lower directions.

[0047] Symmetrical snap-on design: Upper and lower gears 3035 synchronously drive the snap-on plate 3027, avoiding the eccentric force problem of traditional single-sided snaps. After installation, the flatness error of the insulation decorative panel is ≤1.5mm, which exceeds the industry standard (GB / T29906-2013).

[0048] 3. Working logic of the snap-on attachment: Synchronicity 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 by the gear 3035 to rotate synchronously in the opposite direction, ensuring that the upper and lower snap plates 3027 are symmetrically opened and evenly snapped into both sides of the V-shaped groove 501, avoiding unilateral force causing the decorative plate to tilt.

[0049] The stabilizing effect of the abutment plane: the abutment plane 3034 at the end of the support arm 3026 is close to the end face of the insulation board 5, forming a mechanical limit to prevent the snap plate 3027 from being excessively inserted and damaging the decorative board. At the same time, the stress is dispersed through surface contact to improve the connection reliability.

[0050] 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 tensioning rod 3024, forming a "clip-on + tensioning" double locking. The overall wind load resistance is increased by 40% compared to traditional hangers (refer to GB50009-2012 wind load calculation).

[0051] 4. Disassembly and adjustment: Loosen the locking bolts 3028, and the X-shaped frame 3025 moves forward under the reverse tension, allowing the trapezoidal abutment block 3039 to disengage the inclined surface 3037 of the groove 3036. The support arm 3026 retracts synchronously with the meshing action of the gear 3035, and the snap plate 3027 disengages the V-shaped groove 501. The insulation decorative panel can now be easily removed, and the position of the cross keel 2 can be adjusted through the waist-round hole 3015, allowing for quick maintenance or reinstallation.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
