[0043] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0044] See Figures 2 to 9 As shown;

[0045] This embodiment discloses a quick-installation structure suitable for bamboo fiber-calcium silicate composite antibacterial wall panels, which is used to install bamboo fiber-calcium silicate composite antibacterial wall panels 10.

[0046] The quick-assembly structure includes:

[0047] The metal clip base 1, which is connected to the bamboo-calcium silicate composite antibacterial wall panel 10, consists of a base portion 101 fixed to the back of the bamboo-calcium silicate composite antibacterial wall panel 10 by self-tapping screws 3, and a sliding groove portion 102 formed in the base portion 101; and

[0048] The elastic metal clip 2 cooperates with the metal clip base 1, and the elastic metal clip 2 has multiple clip portions 202 that cooperate with the light steel keel 4 of the bamboo-calcium silicate composite antibacterial wall panel 10, so as to fix the light steel keel 4 through the clip portions 202.

[0049] See Figure 1As shown, specifically, this embodiment discloses a bamboo-calcium silicate composite antibacterial wall panel 10, and a quick-assembly structure suitable for assembling the bamboo-calcium silicate composite antibacterial wall panel 10. First, in order to solve the problem of inability to quickly assemble and disassemble in the prior art, a quick-assembly structure of this embodiment is designed based on the structure of the light steel keel 4 and the structure of the composite wall panel. The quick-assembly structure of this embodiment is divided into a metal buckle base 1 and elastic metal clips 2. The metal buckle base 1 is fixed to the back of the composite wall panel by self-tapping screws 3. At the same time, the elastic metal clips 2 are embedded in the sliding groove 102 of the metal buckle base 1. At this time, the clip portion 202 of the elastic metal clips 2 is located on the outside, and can be embedded and engaged with the light steel keel 4 through multiple clips, thereby completing the quick assembly of the composite wall panel and the light steel keel 4.

[0050] First, this embodiment further defines the structure of the bamboo fiber-calcium silicate composite antibacterial wall panel 10, which has a four-layer structure, specifically: the bamboo fiber-calcium silicate composite antibacterial wall panel 10 includes, from bottom to top, a substrate layer 11, an antibacterial film layer 12, a bamboo fiber decorative layer 13, and a surface functional layer 14.

[0051] More specifically, in this embodiment, the substrate layer 11 is an inorganic calcium silicate board with a thickness of 8 mm, and the density of the inorganic calcium silicate board is ≥1.5 g / cm³. 3 Both sides of the inorganic calcium silicate board are sanded to achieve a surface roughness Ra = 3.2μm-6.3μm;

[0052] The antibacterial film layer 12 is made of impregnated film paper containing nano-silver, with a basis weight of 100 g / m³. 2 The pre-impregnated melamine-modified resin and the antibacterial film layer 12 in this embodiment contain 2% nano-silver, resulting in a high antibacterial rate.

[0053] The bamboo fiber veneer layer 13 is 2mm thick and is woven from bamboo fibers with a diameter of 1mm and a weaving density of 6-8 fibers / cm. In this embodiment, the bamboo fiber veneer layer 13 is bonded to the calcium silicate board under high temperature and high pressure (180℃, 8MPa, 7 minutes), and the adhesive film penetrates into the gaps between the bamboo fibers (achieving a filling rate of ≥80%). In addition, the bamboo fiber anti-mildew treatment process involves carbonizing the bamboo fibers and then soaking them in a boric acid solution (boric acid-ethanol solution, concentration 5%).

[0054] The surface functional layer 14 adopts a UV-cured wear-resistant coating with a thickness of 0.1 mm, and the UV-cured wear-resistant coating contains titanium dioxide photocatalyst particles.

[0055] In this embodiment, the light steel keel 4 assembled with the bamboo-calcium silicate composite antibacterial wall panel 10 is divided into multiple longitudinal light steel keels 401 and multiple transverse light steel keels 402.

[0056] The quick-installation structure on the back of the bamboo fiber-calcium silicate composite antibacterial wall panel 10 is assembled and fixed with the corresponding horizontal light steel keel 402.

[0057] Preferably, in this embodiment, the center of the base portion 101 of the metal buckle base 1 is connected to the back of the bamboo-calcium silicate composite antibacterial wall panel 10 by a self-tapping screw 3, and the base portion 101 has two symmetrical positioning grooves 103 on the side that cooperates with the elastic metal clip 2.

[0058] Based on the structure of the metal buckle base 1, the elastic metal buckle teeth 2 in this embodiment include:

[0059] An embedded part 201 is embedded in the groove 102 of the metal buckle base 1; and a plurality of locking teeth 202 are formed on the surface of the embedded part 201 and arranged in a rectangular array, the space between adjacent locking teeth 202 is the embedded interlocking space of the transverse light steel keel 402.

[0060] The side of the insert 201 that mates with the base 101 has a positioning protrusion 203 that is embedded in the corresponding positioning groove.

[0061] The metal buckle base 1 of this embodiment includes an integrally formed base portion 101 and a sliding groove portion 102. The sliding groove portion 102 is formed in the form of a bent structure to allow the insert portion 201 to slide in. At the same time, for positioning, a positioning groove 103 and a positioning protrusion 203 are designed in the base portion 101 and the insert portion 201, respectively. When the insert portion 201 of the elastic metal clip 2 slides into the sliding groove portion 102, the clip portion 202 extends to the outside. At this time, the transverse light steel keel 402 can select a suitable clip portion 202 to be inserted into the space between adjacent clip portions 202, and the transverse light steel keel 402 is connected by elastic deformation and the interlocking action of the clip portions 202.

[0062] During installation, the metal clip base 1 is first pre-fixed to the back of the composite wall panel with self-tapping screws 3. Fasteners are used instead of adhesives to avoid damage to the substrate caused by high temperature and pressure. In this embodiment, the metal clip base 1 is made of lightweight aluminum alloy (tensile strength ≥300MPa) with a thickness of 1.2mm, which matches the expansion coefficient of the composite wall panel.

[0063] A horizontal light steel keel 402 is pre-installed on the wall light steel keel. The locking teeth 202 are arranged in a rectangular array. After pressing, the horizontal light steel keel 402 automatically engages. The locking teeth 202 adopts a column design and the engagement depth is 2mm-3mm.

[0064] Preferably, in this embodiment, a buffer gap is reserved between the metal buckle base 1 and the bamboo-calcium silicate composite antibacterial wall panel 10, specifically: a buffer silicone pad is provided between the metal buckle base 1 and the bamboo-calcium silicate composite antibacterial wall panel 10.

[0065] In this embodiment, the area of ​​the metal buckle teeth 2 is larger than the contact area of ​​the transverse light steel keel 402. Therefore, the buckle connection system as a whole is adjustable. The buckle can be adjusted left and right, allowing lateral displacement. When pressing, the longitudinal displacement can be adjusted by controlling the force, which is convenient for leveling.

[0066] The installation process in this embodiment is greatly innovative: cleaning → positioning → sliding → pressing (four-step operation method) single board installation time ≤90 seconds;

[0067] An installation error compensation mechanism is set up: The snap-fit ​​structure in this embodiment is easy to adjust and can be repeatedly disassembled and reassembled.

[0068] The automatic leveling function of the installation reference surface compensates for the height difference through the metal buckle base 1, resulting in a small flatness error after installation.

[0069] In this embodiment, the UV-cured wear-resistant coating extends to the edge of the board side to protect the snap-fit ​​contact area; the antibacterial film covers the mounting holes to prevent the growth of microorganisms at the connection.

[0070] In the above technical solution, the quick-installation structure provided by this utility model for bamboo fiber-calcium silicate composite antibacterial wall panels has the following beneficial effects:

[0071] This utility model relates to a quick-installation structure for bamboo-calcium silicate composite antibacterial wall panel 10. It is designed with inorganic calcium silicate board as the substrate, bamboo fiber decorative surface layer on the surface, and assembled wall panel made by antibacterial adhesive film bonding process. It is suitable for indoor walls, partitions and other scenarios. The quick-installation structure is applied between the composite wall panel and the light steel keel 4 to achieve quick assembly and disassembly.

[0072] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
