Description

Technical Field

[0001] This utility model belongs to the field of building decoration and renovation technology, specifically relating to an embedded integrated insulation and decoration panel with hidden locking mechanism, which is suitable for quick-installation wall systems for exterior or interior walls of public buildings, commercial complexes and residences. Background Technology

[0002] With the popularization of prefabricated and green building concepts, integrated exterior wall insulation and decoration systems are widely used. Existing technologies mainly employ two fixing methods: one is exposed aluminum alloy strips or exposed bolts for dry hanging; the other is on-site adhesive bonding followed by point anchoring for reinforcement. These two methods have long revealed the following pain points in actual projects: 1. Exposed latches, bolts, or trim strips not only damage the integrity of the facade but also easily create sharp-edge safety hazards, especially in densely populated public buildings, schools, and commercial streets, where pedestrians frequently scrape and graz the surfaces. At the same time, exposed metal is subject to rain, salt spray, and corrosion over a long period of time, which increases the cost of cleaning and replacement later.

[0003] 2. The insulation layer and the decorative layer generally need to be laminated on the construction site. On-site application of adhesive, anchoring, or wet application are greatly affected by the ambient temperature and humidity and the skills of the workers. Uneven adhesive layer thickness, hollow areas, and weak adhesion often occur, leading to sagging of the insulation layer and detachment of the decorative layer later, resulting in high risks of high-altitude repairs.

[0004] 3. Although traditional embedded structures can achieve a flush surface, they mostly rely on screw tightening or back bolt compression. Disassembling a single piece requires loosening each bolt one by one, resulting in low efficiency for high-altitude operations. Furthermore, embedded nodes lack lateral elastic restraint, and seasonal temperature differences can cause the board seams to expand or contract, easily leading to "bulging" or "corner breakage," which can cause the sealant to crack and further accelerate rainwater infiltration and frost heave damage.

[0005] 4. Most existing quick-install locks are visible push-button type with exposed locking tongues, which become stuck and fail after dust accumulation; moreover, the locking points are usually only arranged in the center of the back of the panel, without auxiliary limiting around the perimeter. When the long side is greater than 600 mm, the panel surface is prone to "warping", affecting the flatness of the facade.

[0006] Therefore, the market urgently needs a new type of decorative panel system that features "no visible latches on the surface, integrated molding of insulation and decoration in the factory, quick one-handed assembly and disassembly, and two-way hidden locking on all four sides" to solve the comprehensive pain points of aesthetics, safety, efficient maintenance, and long-term flatness. Utility Model Content

[0007] This utility model aims to overcome the defects of existing thermal insulation and decorative panels, such as exposed buckles, unstable quality of on-site secondary composite, cumbersome disassembly, and insufficient lateral restraint. It provides an embedded integrated thermal insulation and decorative panel with no visible buckles on the surface, which is integrally molded in the factory for thermal insulation and decoration, can be quickly disassembled and assembled with one hand, and has bidirectional hidden restraint on all four sides. This achieves the goals of a flat and beautiful facade, efficient installation, damage-free maintenance, and long-term safety and reliability.

[0008] To achieve the above purpose, the present utility model is implemented as follows: An embedded thermal insulation and decoration integrated plate with hidden lock catches, comprising: an embedding frame 1, which is in a shape of Chinese character "Tian", is provided with a plurality of positioning frames 3, the top and bottom of each frame are provided with through openings 4, the left and right sides are provided with fastening buckles 9 and retractable protruding strips 10, and retractable springs 11 are arranged inside the protruding strips; the decoration plate 2 is composed of a thermal insulation layer 21 and a decoration layer 22 which are prefabricated into a whole in a factory, and the two are connected by mortise and tenon through inner splayed embedding grooves 5 and outer splayed embedding protrusions 6; the upper and lower sides of the thermal insulation layer 21 are provided with spring grooves, in which button springs 7 and fan-shaped limit plates 8 are arranged, and the left and right sides are provided with cylindrical grooves 23; during installation, push the decoration plate 2 into the positioning frame 3, the retractable protruding strips 10 automatically extend out and insert into the cylindrical grooves 23, and at the same time the fan-shaped limit plates 8 are embedded into the through openings 4, so as to realize bidirectional hidden lock catches in the vertical and horizontal directions; during disassembly, first pull out the protruding strips 10, then press the limit plates 8 with a thin plate, so that the decoration plate 2 can be taken out as a whole without damaging the plate surface.

[0009] Further, the outer surface of the decoration layer 22 is entirely coated with diatom mud, which has the functions of humidity regulation, scrub resistance and antistatic property, no additional coating is required on the facade, and on-site wet operation is reduced.

[0010] Further, the embedding grooves 5 and the embedding protrusions 6 have inner and outer splayed cross-sections, and are subjected to factory high-pressure lamination, which ensures that the shear resistance between the thermal insulation layer and the decoration layer is ≥ 0.15 MPa, and avoids delamination and blistering under long-term temperature difference.

[0011] Further, the front end of the retractable protruding strip 10 is a hemispherical head, and the inlet of the cylindrical groove 23 is provided with a 1×45° chamfer. During the pushing process, the protruding strip automatically retracts under guidance, and the installation can be completed with one hand, which improves the efficiency of high-altitude operation.

[0012] Further, the gap between the outer arc of the limit plate 8 and the edge of the through opening 4 is ≤ 0.5 mm. After embedding, the up-and-down jumping of the decoration plate is immediately restricted, and the temperature difference displacement of ±1 mm is absorbed, so as to keep the facade flat.

[0013] Further, both the retractable springs 11 and the button springs 7 are made of 06Cr19Ni10 stainless steel, which are all hidden inside the positioning frame 3 and the thermal insulation layer 21, with no exposed metal on the surface, eliminating the risk of rust and scratching.

[0014] Further, the back of the positioning frame 3 is reserved with a T-shaped dry-hanging groove or a plane bonding groove, which is compatible with both aluminum alloy keel and chemical adhesive in two modes, and adapts to a variety of base layers such as concrete walls, steel structures, and light-weight partition walls.

[0015] Further, the fitting gap between the periphery of the decoration plate 2 and the positioning frame 3 is ≤ 1 mm, and the flatness of the finished surface is ≤ 0.5 mm / 2 m, with no visible shadow to the naked eye, eliminating the protrusions of traditional pressing strips or screw caps.

[0016] Further, the insulation layer 21 may adopt Class A rock wool or graphite polystyrene board, with a thermal conductivity of ≤0.040 W / (m·K), and a thickness of 30-100 mm that can be freely selected according to energy-saving calculation without modifying the locking structure.

[0017] Further, all locking parts are made of metal elastomer, which can be disassembled and reassembled more than 50 times. Both the frame and the decorative board can be recycled, meeting the high-frequency maintenance scenarios such as schools and hospitals.

[0018] The utility model adopts the above design to form systematic innovation in five dimensions of "hidden lock - factory integration - one-handed quick disassembly - zero exposure - recyclability", and achieves the comprehensive goals of long-term safety, aesthetics and easy maintenance of the insulation decorative board.
