Description

Technical Field

[0001] This utility model belongs to the technical field of wear-resistant multilayer boards, and particularly relates to a wear-resistant multilayer board. Background Technology

[0002] Currently, in fields such as industrial production, building decoration, and equipment manufacturing, wear-resistant multilayer boards face increasingly stringent performance requirements due to the need to simultaneously withstand complex working conditions such as wear and high temperatures. However, existing wear-resistant multilayer boards have significant shortcomings in structural design and functional adaptability, making it difficult to meet the long-term use needs of high-wear and high-risk scenarios.

[0003] Among them, existing fire-resistant multilayer boards mostly use traditional welding or bonding methods to fix fire-resistant components. On the one hand, welding requires professional equipment and operators, the assembly process is complex and time-consuming, and high-temperature welding can easily cause deformation of the board substrate, affecting the overall structural accuracy. On the other hand, bonding fixation relies on chemical adhesives such as glue. During long-term use, the adhesive is easily aged and degraded by temperature changes and vibrations, causing the fire-resistant components to shift or fall off, thus losing their fire-resistant barrier function. In addition, some multilayer boards, in order to simplify assembly, only set fire-resistant materials on the surface or a single interlayer, without forming a multi-level fire-resistant structure. When exposed to high-temperature environments, heat can easily penetrate the board quickly, causing damage to the internal structure and failing to achieve long-lasting fire-resistant protection.

[0004] Therefore, we propose a wear-resistant multilayer board to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a wear-resistant multilayer board that achieves fireproof and wear-resistant effects.

[0006] In view of this, the present invention provides a wear-resistant multilayer board, comprising: a base plate having an inner cavity; an inner plate embedded in the inner cavity; multiple refractory fiber ceramic plates; a connecting plate, wherein the base plate, the inner plate, and the connecting plate are fixed by a connecting assembly; and an outer plate having a wear-resistant layer on its outer surface. The connecting assembly includes a plurality of first holes formed on the connecting plate, a plurality of second holes formed on the inner plate, wherein the inner diameter of the first holes is the same as the inner diameter of the second holes, and a plurality of third holes are formed in communication with the inner side of the inner cavity. Bolts are threadedly connected to the corresponding first holes and second holes.

[0007] Furthermore, several mounting slots are provided in the inner plate, and rivet grooves are provided in the center of each of the four sides of the mounting slots. Rivet blocks are fixedly connected to the center of each of the four sides of the refractory fiber ceramic plate, and the rivet blocks and rivet grooves fit together.

[0008] Furthermore, the substrate has an inner cavity extending through one end face, and the cavity wall shape, cross-sectional dimensions, and depth dimensions are adapted to the outer peripheral shape, cross-sectional dimensions, and thickness dimensions of the inner plate, respectively.

[0009] Furthermore, an adhesive sheet is provided between the connecting plate and the outer plate, and the two sides of the adhesive sheet are respectively bonded to the sidewalls of the connecting plate and the outer plate.

[0010] Furthermore, the outer panel is made of epoxy resin board, and the wear-resistant layer is a tungsten carbide coating, which is sprayed onto the surface of the outer panel by spraying.

[0011] Furthermore, both sides of the inner plate are sprayed with filler adhesive, and the filler adhesive extends and is distributed on the surface of multiple refractory fiber ceramic plates.

[0012] The beneficial effects of this utility model are: The refractory fiber ceramic panels installed in the inner plate via quick-installation components ensure excellent fire resistance. These components simplify the installation process and effectively limit the movement of the panels, preventing displacement during use. The connecting components, while fixing the base plate, inner plate, and connecting plate, further reinforce the refractory fiber ceramic panels within the inner plate, enhancing the overall structural stability. The outer plate installed via connectors on the outside of the connecting plate, along with the internal wear-resistant layer, provides excellent wear resistance to the panel surface, making it suitable for use in high-wear environments.

[0019] Reference Figures 1 to 5 A wear-resistant multilayer board, comprising: Substrate 1 has an inner cavity 11; Inner plate 12 is embedded in inner cavity 11; Refractory fiber ceramic plates 23 are provided in multiple quantities; The connecting plate 13, the base plate 1, the inner plate 12 and the connecting plate 13 are fixed by a connecting assembly; Outer panel 15, with a wear-resistant layer on the outside of the outer panel 15.

[0020] This application achieves a stable connection between the inner panel 12 and the base plate 1 through interlocking. The base plate 1 is a solid wood board, utilizing its own structural strength to bear the overall external force. The inner panel 12, as the core carrier of the fire-resistant function, supports multiple fire-resistant fiber ceramic plates 23. Utilizing the high-temperature resistant material properties of the ceramic plates, a multi-layer fire-resistant barrier is formed. When a high-temperature environment occurs, the fire-resistant fiber ceramic plates 23 can block heat transfer through their own high-temperature resistance properties, preventing damage to the internal structure due to high temperatures. Simultaneously, through the interlocking relationship between the inner panel 12 and the base plate 1, and since the inner panel 12 is made of fire-resistant plywood, the ceramic plates are stably fixed in the preset position, ensuring the continuous fire-resistant function. Effective; the connecting components are mechanically fixed and penetrate the substrate 1, inner plate 12 and connecting plate 13. The connecting plate 13 is made of plywood. The rigid constraint of bolts 33 eliminates the gap between layers, so that the three-layer structure forms a unified whole under stress, avoiding relative displacement between layers due to external forces and ensuring the stability of the overall structure; the outer plate 15 is a surface protective structure. Its wear-resistant layer is in direct contact with the outside world. When subjected to friction, the wear-resistant layer uses its own high hardness material properties to resist wear, reduce damage to the outer plate 15 itself, and achieve the dual function of wear resistance and protection, so that the multilayer board can work stably in wear-resistant and fire-resistant scenarios.

[0021] In the example of this application, a plurality of mounting grooves 21 are opened in the inner plate 12, and rivet grooves 22 are opened in the center of each of the four sides of the mounting grooves 21. Rivet blocks 24 are fixedly connected to the center of each of the four sides of the refractory fiber ceramic plate 23, and the rivet blocks 24 and the rivet grooves 22 fit together.

[0022] As a preferred example of this utility model, during the assembly stage, the pre-set mounting groove 21 of the inner plate 12 provides an initial placement space for the refractory fiber ceramic plate 23. Simultaneously, the rivet grooves 22 in the center of the four sides of the mounting groove 21 form a precise matching relationship with the rivet blocks 24 on the four sides of the ceramic plate. The operator only needs to align the rivet blocks 24 of the ceramic plate with the rivet grooves 22 and apply slight pressure to quickly position the ceramic plate. Physical interlocking replaces traditional welding or adhesive fixing, simplifying the assembly process. During the usage stage, the engagement of the rivet blocks 24 and the rivet grooves 22 forms a lateral constraint, preventing external vibration or impact. When struck, the inner wall of the rivet groove 22 generates a lateral reaction force on the rivet block 24, restricting the horizontal displacement of the ceramic plate and preventing the ceramic plate from detaching from the preset position due to vibration. At the same time, the bottom structure of the mounting groove 21 provides longitudinal support for the ceramic plate. When the ceramic plate is subjected to vertical pressure, the bottom of the groove disperses the force on the ceramic plate by bearing the pressure, preventing the ceramic plate from breaking due to excessive local stress. Through the synergistic effect of lateral limiting and longitudinal support, the ceramic plate is kept in the preset installation position, ensuring the stable performance of the fire-resistant function, while reducing the maintenance needs during assembly and use.

[0023] In the example of this application, an inner cavity 11 is provided in the substrate 1, which extends through one end face. The cavity wall shape, cross-sectional dimensions and depth dimensions of the inner cavity 11 are adapted to the outer peripheral shape, cross-sectional dimensions and thickness dimensions of the inner plate 12, respectively.

[0024] As a preferred example of this utility model, the cavity wall shape, cross-sectional dimensions, and depth dimensions of the inner cavity 11 of the substrate 1 are completely consistent with those of the inner plate 12. When the inner plate 12 is embedded in the inner cavity 11, the outer peripheral wall of the inner plate 12 and the cavity wall of the inner cavity 11 form a seamless fit, eliminating interlayer gaps and using physical contact to block the entry channels of impurities such as dust and moisture, thus avoiding structural corrosion or friction damage caused by the accumulation of impurities between layers. Secondly, in terms of force transmission, the seamless fit structure allows the external force on the inner plate 12 to be uniformly transmitted to the substrate 1 through the contact surface, avoiding force concentration caused by local gaps. When an external impact is applied, the substrate 1 can disperse the impact force to the entire surface of the substrate 1 through large-area contact, reducing local stress and reducing deformation or breakage of the substrate 1 or the inner plate 12 due to stress concentration. Finally, in terms of assembly efficiency, the size adaptability allows the inner plate 12 to be directly embedded into the substrate 1 without additional adjustment, reducing auxiliary processes such as grinding and filling in traditional assembly. At the same time, the seamless fit ensures that the surface of the board is flat after assembly, avoiding appearance defects caused by dimensional deviations.

[0025] In the example of this application, the connecting assembly includes a plurality of first holes 3 opened on the connecting plate 13, a plurality of second holes 31 opened on the inner plate 12, the inner diameter of the first holes 3 being the same as the inner diameter of the second holes 31, a plurality of third holes 32 opened on the inner side of the inner cavity 11, a nut being fixedly installed in each third hole 32, and a bolt 33 being threadedly connected to the corresponding first holes 3 and second holes 31, and the bolt 33 being threadedly connected to the nut in the third hole 32.

[0026] As a preferred example of this utility model, the first hole 3 of the connecting plate 13, the second hole 31 of the inner plate 12, and the third hole 32 of the inner cavity 11 of the base plate 1 are coaxially aligned. Since the inner diameters of the first hole 3 and the second hole 31 are the same and are compatible with the outer diameter of the bolt 33, the bolt 33 can smoothly pass through the first two holes and form a threaded connection with the internal thread of the third hole 32. Through the self-locking characteristic of the thread, the bolt 33 generates an axial preload, which tightly presses the connecting plate 13, the inner plate 12, and the base plate 1 together, eliminating interlayer gaps and forming a rigid connection, thus avoiding relative slippage between layers. Secondly, during the force transmission stage, the distributed arrangement of multiple holes and bolts 33 allows external forces to be transmitted to each bolt 33 through the connecting plate 13. Each bolt 33 bears part of the external force. Through the force dispersion effect, the load on a single bolt 33 is reduced, avoiding breakage or loosening caused by overload of a single bolt 33. At the same time, the rigid structure of the bolt 33 can quickly transmit external forces to the base plate 1, using the load-bearing capacity of the base plate 1 to disperse the overall force and improve the impact resistance of the structure.

[0027] In the example of this application, a glue plate 14 is provided between the connecting plate 13 and the outer plate 15, and the two sides of the glue plate 14 are respectively bonded to the side walls of the connecting plate 13 and the outer plate 15.

[0028] As a preferred example of this utility model, the adhesive plate 14 is fully bonded to the sidewalls of the connecting plate 13 and the outer plate 15 by means of adhesive bonding. The adhesive plate 14 fills the tiny gaps between the layers by its own adhesive properties, forming a continuous sealing barrier. Moreover, the adhesive strength of the adhesive plate 14 can ensure the connection stability between the outer plate 15 and the connecting plate 13, and prevent the outer plate 15 from detaching from the connecting plate 13 due to impact.

[0029] In the example of this application, the outer panel 15 is made of epoxy resin board, and the wear-resistant layer is a tungsten carbide coating 16, which is sprayed onto the surface of the outer panel 15 by spraying.

[0030] As a preferred example of this utility model, the tungsten carbide coating 16 is applied to the surface of the outer panel 15 by spraying. On the one hand, this allows the tungsten carbide coating 16 to form a uniform and continuous covering layer on the epoxy resin board surface, avoiding problems such as local missed coatings and uneven thickness, and ensuring consistent wear resistance across all areas of the outer panel 15 surface. On the other hand, the spraying process is well adapted to the surface characteristics of the epoxy resin board, improving the bonding strength between the coating and the substrate of the outer panel 15. Furthermore, utilizing the extremely high hardness and wear resistance of tungsten carbide itself, the wear resistance of the outer panel 15 surface can be significantly enhanced. Compared to an epoxy resin board without a coating, it can effectively resist surface damage caused by friction, scratches, or impacts from external objects during use, extending the service life of the outer panel 15 and reducing structural maintenance costs.

[0031] In the example of this application, both sides of the inner plate 12 are sprayed with filler adhesive 34, and the filler adhesive 34 extends and is distributed on the surface of multiple refractory fiber ceramic plates 23 for filling the gaps between the refractory fiber ceramic plates 23 and the substrate 1, the inner plate 12 and the connecting plate 13.

[0032] As a preferred example of this utility model, in terms of sealing and protection, the filler adhesive 34 is applied by spraying to cover both sides of the inner panel 12 and the surface of the ceramic plate. The filler adhesive 34 is a high-temperature resistant silicone sealant. Utilizing the fluidity of the adhesive, it penetrates into the tiny gaps between the inner panel 12 and the ceramic plate. After curing, it forms a continuous sealing layer, blocking the intrusion path of moisture, dust, and other impurities, preventing structural corrosion caused by the accumulation of impurities in the gaps. Simultaneously, the sealing layer reduces sound transmission, improving the overall sound insulation effect of the board by utilizing the sound insulation properties of the adhesive. Secondly, in terms of impact buffering, the filler adhesive 34 has a certain degree of elasticity after curing. When external impact force is transmitted to the ceramic plate, the filler adhesive 34 absorbs part of the impact through its own elastic deformation. Impact energy is reduced, minimizing the direct impact force on the ceramic plate and preventing breakage due to its brittle nature. Elastic deformation also disperses the impact force, converting concentrated impact into dispersed stress and reducing the risk of damage. Finally, at the structural connection level, the filler adhesive 34 tightly connects the inner plate 12 to the ceramic plate through bonding. The cured adhesive forms a rigid bonding layer, replacing traditional mechanical fastening, eliminating interlayer gaps, and making the inner plate 12 and the ceramic plate a unified whole under stress. When subjected to external force, both share the load, preventing the ceramic plate from loosening or falling off due to individual stress. Simultaneously, the bonding layer improves the overall structural flatness and reduces appearance defects caused by gaps.

[0033] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
