Description

Technical Field

[0001] This utility model belongs to the field of composite board technology, and in particular relates to a wear-resistant composite board. Background Technology

[0002] In the field of composite panel technology, wear-resistant composite panels, due to their combination of strength and wear resistance, are widely used in industrial settings such as mining, building materials, and metallurgy to meet needs such as material conveying and equipment protection. However, currently available wear-resistant composite panels still suffer from two major problems in structural design and installation, which seriously affect their service life and construction efficiency.

[0003] On the one hand, traditional wear-resistant composite panels mostly use a single connection method for fixing: some rely on mechanical fasteners (such as bolts and rivets) for connection, which requires drilling holes in the panel during installation. This not only damages the integrity of the panel structure and reduces the overall strength, but also makes the fasteners prone to loosening and falling off under long-term vibration and impact loads, leading to panel separation. On the other hand, some are fixed by adhesive, which requires applying adhesive to the connection surface of the panel in advance. Additional support is needed for positioning before the adhesive cures, which is cumbersome. Moreover, the adhesive is easily affected by ambient temperature and humidity, and the bonding strength decreases after long-term use, which also poses a risk of panel detachment.

[0004] On the other hand, the traditional composite panel installation process is complicated, requiring multiple steps such as positioning, fixing and fastening. The installation of a single panel takes a long time, and in large-scale laying scenarios, the overall construction efficiency is low, which cannot meet the rapid construction needs of industrial projects. Therefore, we propose a wear-resistant composite panel. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a wear-resistant composite board that achieves rapid installation and adhesion.

[0006] In view of this, the present invention provides a wear-resistant composite plate, including a first plate body, a second plate body, a first coupling part, and a second coupling part. The first plate body and the second plate body are coupled through the first coupling part and the second coupling part. Both the first coupling part and the second coupling part are provided with piercing components, and both the first plate body and the second plate body have built-in glue bladders. The coupling of the first plate body and the second plate body can drive the piercing components to pierce the glue bladders, and the glue bladders will flow out glue to stick and fix the first plate body and the second plate body.

[0007] Furthermore, the first coupling part includes a first coupling groove opened at the upper inner side of the first plate, the second coupling part includes a second coupling groove opened in the middle of the second plate, a first irregular strip is provided on the side of the first plate near the second coupling groove, and a second irregular strip is provided on the side of the second plate near the first coupling groove.

[0008] Furthermore, the first irregular strip is integrally formed with the first plate, the second irregular strip is integrally formed with the second plate, and the first irregular strip is disposed below the second irregular strip.

[0009] Furthermore, both the first plate and the second plate are provided with a wear-resistant layer at their upper ends, and the wear-resistant layer is formed by spraying Cr3C2-NiCr cermet powder.

[0010] Furthermore, the upper end of the first irregular strip is provided with a locking concave surface, and the lower end of the second irregular strip is provided with a locking convex surface. The size of the locking concave surface is adapted to the size of the locking convex surface, and the locking concave surface and the locking convex surface are in contact.

[0011] Furthermore, a groove is provided at the lower end of the second plate, and the groove is located below the second coupling groove, and the groove is connected to the second coupling groove.

[0012] Furthermore, the left inner wall of the first coupling groove and the upper inner wall of the second coupling groove are both provided with glue bladders, and the upper end of the first irregular strip and the left end of the second irregular strip are both integrally formed with puncture heads, and the puncture heads correspond to the glue bladders.

[0013] Furthermore, the glue bag is made of rubber, and the inner cavity of the glue bag is filled with composite board adhesive. The glue bag is configured to be multiple and adhered to the inner walls of the first coupling groove and the second coupling groove.

[0014] The beneficial effects of this utility model are:

[0015] The first and second panels are physically coupled through the first and second coupling parts. Simultaneously, during coupling, the piercing component punctures the adhesive sac, allowing adhesive to flow out and achieve bonding and fixation, thus achieving a double-fixation effect. This significantly enhances the strength of the connection between the two panels, effectively preventing panel separation due to vibration or impact during use, and extending the overall lifespan of the composite panel. Furthermore, no additional adhesive is required during installation; the coupling action alone triggers the adhesive bonding process, reducing installation steps and simplifying the operation for construction workers. Compared to the traditional composite panel installation method that requires positioning, then applying adhesive, and finally fixing, this significantly shortens the installation time for a single composite panel, greatly improving overall construction efficiency, especially in large-scale installation scenarios.

[0026] Reference Figures 1 to 3 A wear-resistant composite board includes a first plate body 1, a second plate body 11, a first coupling part, and a second coupling part. The first plate body 1 and the second plate body 11 are coupled through the first coupling part and the second coupling part. Both the first coupling part and the second coupling part are provided with piercing components, and both the first plate body 1 and the second plate body 11 have built-in glue sacs 25. The coupling of the first plate body 1 and the second plate body 11 can drive the piercing components to pierce the glue sacs 25, and glue flows out of the glue sacs 25 to stick and fix the first plate body 1 and the second plate body 11 together.

[0027] This application is approved. During installation, the first plate 1 and the second plate 11 are pushed closer together by external force, so that the first coupling part and the second coupling part form a physical fit, completing the initial positioning and mechanical fixation. During the continuous fitting of the coupling parts, the piercing components on the first coupling part and the second coupling part will gradually contact and squeeze the glue sac 25 built into the plate. As the fitting depth increases, the squeezing force of the piercing component exceeds the strength of the sac wall of the glue sac 25, piercing the sac wall. The adhesive in the glue sac 25 flows out under its own elasticity or gravity and fills the coupling gap between the two plates. After the adhesive cures, a chemical adhesive connection is formed on the basis of mechanical fitting, ultimately achieving the effect of double fixation and avoiding the relative separation of the two plates.

[0028] It is worth noting that both the first plate 1 and the second plate 11 are composite boards, which are made by cross-jointing and hot-pressing multiple layers of plywood.

[0029] In the example of this application, the first coupling part includes a first coupling groove 14 opened at the upper inner side of the first plate 1, and the second coupling part includes a second coupling groove 15 opened in the middle of the second plate 11. A first irregular strip 2 is provided on the side of the first plate 1 near the second coupling groove 15, and a second irregular strip 23 is provided on the side of the second plate 11 near the first coupling groove 14.

[0030] As a preferred example of this utility model, the first coupling groove 14 of the first plate 1 and the second coupling groove 15 of the second plate 11 provide a preset fitting channel for the irregular strip. During installation, the irregular strip can slide along the inner wall of the coupling groove, and the side wall of the coupling groove forms a lateral limit on the irregular strip to prevent the irregular strip from shifting left or right during the fitting process. At the same time, the length direction of the irregular strip is consistent with the depth direction of the coupling groove, ensuring that the two plates fit together in a preset vertical direction, and finally achieving the positioning of the first plate 1 and the second plate 11, ensuring the flatness after connection.

[0031] In the example of this application, the first irregular strip 2 is integrally formed with the first plate 1, the second irregular strip 23 is integrally formed with the second plate 11, and the first irregular strip 2 is disposed below the second irregular strip 23.

[0032] As a preferred example of this utility model, since the first irregular strip 2 and the first plate 1, and the second irregular strip 23 and the second plate 11 are integrally formed, there are no interface gaps or weak joint areas for secondary connections. When an external force is applied to the irregular strip, the force can be directly transmitted from the irregular strip to the interior of the plate, and the transmission path is continuous and uniform, without stress concentration or force loss at the interface. This ensures that the connection strength between the irregular strip and the plate is equal to the strength of the plate itself, preventing the irregular strip from falling off due to interface breakage. When the composite plate is subjected to a vertical load, the load is transmitted to the two irregular strips through the surface of the plate. The upper second irregular strip 23 first contacts the load and transmits part of the force to its corresponding coupling groove. The lower first irregular strip 2 simultaneously bears the remaining load and transmits it to its coupling groove. The two irregular strips and their corresponding coupling grooves jointly bear the vertical pressure, distributing the load in the vertical direction to two stress points, rather than concentrating it on a single irregular strip. This reduces the stress load on a single irregular strip, thereby improving the overall load-bearing capacity.

[0033] In the example of this application, the upper ends of the first plate 1 and the second plate 11 are both provided with a wear-resistant layer 12, and the wear-resistant layer 12 is sprayed with Cr3C2-NiCr metal ceramic powder.

[0034] As a preferred example of this utility model, Cr3C2-NiCr cermet powder is applied to the upper surfaces of the first plate 1 and the second plate 11 through a thermal spraying process to form a wear-resistant layer 12. On the one hand, this enhances the bonding force between the wear-resistant layer 12 and the plate substrate, preventing the wear-resistant layer 12 from falling off under impact. On the other hand, NiCr has good oxidation resistance and can form a dense oxide film in a high-temperature environment, preventing oxygen and corrosive media from contacting the plate substrate, avoiding oxidation or corrosion of the substrate, thereby extending the service life of the composite plate.

[0035] In the example of this application, the upper end of the first irregular strip 2 is provided with a locking concave surface 22, and the lower end of the second irregular strip 23 is provided with a locking convex surface 21. The size of the locking concave surface 22 is adapted to the size of the locking convex surface 21, and the locking concave surface 22 and the locking convex surface 21 are in contact.

[0036] As a preferred example of this utility model, the locking concave surface 22 of the first irregular strip 2 and the locking convex surface 21 of the second irregular strip 23 are complementary curved surface structures. When the two irregular strips are fitted together, the convex surface can be completely embedded in the concave area of ​​the concave surface, so that the contact surfaces of the two are tightly fitted. Furthermore, the contact surfaces of the locking concave surface 22 and the locking convex surface 21 are non-smooth matching curved surfaces. When the composite plate is subjected to vibration or lateral displacement, the two irregular strips tend to slide relative to each other. At this time, the inner wall of the concave surface will generate a lateral squeezing force on the convex surface, while the convex surface will generate a reaction force on the concave surface. This mutual squeezing force forms a self-locking friction force, which prevents the two irregular strips from moving along the sliding direction and further restricts the relative displacement, thereby achieving the anti-loosening effect.

[0037] In the example of this application, a groove 13 is provided at the lower end of the second plate 11, and the groove 13 is located below the second coupling groove 15, and the groove 13 is connected to the second coupling groove 15.

[0038] As a preferred example of this utility model, the groove 13 at the lower end of the second plate 11 is connected to the second coupling groove 15. The groove 13 facilitates the first irregular strip 2 to be inserted into the second coupling groove 15 from the groove 13, thereby facilitating the installation of the first plate 1 and the second plate 11.

[0039] In the example of this application, the left inner wall of the first coupling groove 14 and the upper inner wall of the second coupling groove 15 are both provided with glue bags 25, and the upper end of the first irregular strip 2 and the left end of the second irregular strip 23 are both integrally formed with puncture heads 24, and the puncture heads 24 correspond to the glue bags 25.

[0040] As a preferred example of this utility model, when the two plates are coupled, the trajectory of the irregular strip along the coupling groove is completely consistent with the trajectory of the puncture head 24 approaching the glue sac 25. As the coupling action progresses, the puncture head 24 will accurately contact the preset weak area (such as the thinner part of the sac wall) of the glue sac 25, ensuring that each glue sac 25 can be contacted and punctured by the corresponding puncture head 24, avoiding the situation where the glue sac 25 is not punctured due to positional deviation.

[0041] In the example of this application, the glue bag 25 is made of rubber, and the inner cavity of the glue bag 25 is filled with composite board adhesive. The glue bag 25 is configured to be bonded to the inner walls of the first coupling groove 14 and the second coupling groove 15.

[0042] As a preferred example of this utility model, the adhesive bladder 25 is made of rubber. Rubber has good elasticity and sealing properties, and the bladder wall can completely enclose the internal composite board adhesive, preventing air and moisture from entering the bladder and reacting with the adhesive. During transportation and handling, if the adhesive bladder 25 is subjected to a slight impact, the elasticity of the rubber will buffer the external impact force, reduce the stress damage to the bladder wall, prevent premature adhesive leakage, and ensure that the adhesive maintains good performance during installation. Moreover, multiple adhesive bladders 25 are bonded at a certain interval within the first coupling groove 14 and the second coupling groove 15. When all adhesive bladders 25 are punctured, each adhesive bladder 25 will release a certain amount of adhesive. Because the adhesive bladders 25 are evenly distributed, the released adhesive will form multiple "adhesive points" within the coupling groove. These adhesive points are interconnected, filling the entire coupling gap, making the adhesive distribution more uniform at the coupling site. This avoids insufficient adhesive strength in some areas due to too little adhesive, or accumulation due to too much adhesive, ultimately achieving uniform adhesion between the two plates and ensuring consistent connection strength.

[0043] 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.
