Description

Technical Field

[0001] The invention relates to the technical field of fiberboards, in particular to a high-strength and wear-resistant fiberboard. Background Art

[0002] Fiberboard, also known as density board, is a man-made board made of wood fiber or other plant fiber as raw materials, with urea-formaldehyde resin or other suitable adhesives applied. Fiberboard has the advantages of uniform material, small difference in vertical and horizontal strength, and not easy to crack. It has a wide range of uses.

[0003] After searching, a Chinese patent with announcement number CN216069037U discloses a high-strength wear-resistant fiberboard, including a lower fiber base plate, a fourth impact-resistant mesh layer, a sound insulation layer, a third impact-resistant mesh layer, a noise reduction layer of a honeycomb structure, a second impact-resistant mesh layer, a pressure-resistant layer, a first impact-resistant mesh layer, an upper fiber base plate and a wear-resistant layer. The above device can make the fiber composite board have better impact resistance, indirectly improve the strength of the fiber composite board, and at the same time, through the combination of multi-layer structures, the fiberboard has high strength and wear resistance, and has good sound insulation effect, which is suitable for a variety of occasions.

[0004] Based on the existing technologies, the above patents still have the following deficiencies: the fiberboard only improves the wear resistance of the entire board by setting a wear-resistant layer on the top of the upper fiberboard, which has a poor effect on improving the wear resistance of the entire board. At the same time, the board has a total of seven layers of structure inside to improve the overall strength. Although it can play a good role in strengthening the board body, it will lead to a thicker board body and heavier weight, which not only increases the production cost of the board, but also does not meet people's demand for lightweight boards. Therefore, a high-strength wear-resistant fiberboard is urgently needed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and propose a high-strength wear-resistant fiberboard.

The ceramic reinforcing column has good smoothness on its surface, thereby reducing the friction between the object and effectively reducing wear. The ceramic reinforcing column is equidistantly distributed in the assembly groove on the top of the second layer of the board.

DETAILED DESCRIPTION

[0049] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0050] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0051] Reference Figure 1-Figure 11 A high-strength wear-resistant fiberboard comprises a first layer board 1 and a second layer board 2, wherein the second layer board 2 is arranged on the top of the first layer board 1, and a wear-resistant component 3 is arranged on the top of the second layer board 2;

[0052] The first layer board 1 and the second layer board 2 are both made of fiber materials;

[0053] A reinforcing assembly 5 is provided on the top of the first layer board 1, and a vertical plate 7 is fixedly connected to the top of the first layer board 1, and the vertical plate 7 and the top of the reinforcing assembly 5 are both in contact with the bottom of the second layer board 2;

[0054] Side panels 4 are bonded to both outer walls of the first layer 1 and the second layer 2;

[0055] The wear-resistant component 3 includes an assembly groove 3002 provided on the top outer wall of the second layer plate 2, a matching portion 3004 is provided on the circumferential inner wall of the assembly groove 3002, a ceramic reinforcing column 3003 is clamped inside the assembly groove 3002, a first clamping groove 3005 is provided on the circumferential outer wall of the ceramic reinforcing column 3003, the first clamping groove 3005 and the matching portion 3004 are clamped with each other, and a wear-resistant coating 3001 is sprayed on the top outer wall of the second layer plate 2, and the wear-resistant coating 3001 covers the top of the ceramic reinforcing column 3003;

[0056] A clamping assembly 8 is provided on the top of the vertical plate 7 to ensure stable bonding between the first layer plate 1 and the second layer plate 2;

[0057] An adhesive component 6 is arranged inside the assembly groove 3002. When the fiberboard is used, the wear-resistant coating 3001 located on the top of the second layer 2 will first come into contact with objects, the ground, etc. Since the wear-resistant coating 3001 is made of ceramic granular material, its hardness is much higher than that of ordinary metal surfaces, so it can resist the impact of high-speed particles or fluids without being worn. When the board is used in an environment with very severe wear, even if the wear-resistant coating 3001 is completely worn out, the top of the ceramic reinforcing column 3003 located in the assembly groove 3002 will completely leak out. The ceramic reinforcing column 3003 has good surface Good smoothness can reduce the friction between objects and effectively reduce wear. The top of the ceramic reinforcing column 3003 is higher than the top of the second layer of board 2, thus effectively avoiding the second layer of board 2 from directly contacting the object and causing increased wear, and has a good protective effect on the entire fiberboard. The ceramic reinforcing column 3003 is equidistantly distributed in the assembly groove 3002 on the top of the second layer of board 2. Due to its own good hardness, it can not only play a wear-resistant effect, but also can strengthen the second layer of board 2, ensuring the strength of the entire fiberboard.

[0058] In order to make the ceramic reinforcement column 3003 and the second layer plate 2 fastened together, refer to Figure 2 The bonding component 6 includes an arc groove 6003 opened on the circumferential outer wall of the ceramic reinforcement column 3003, and the arc groove 6003 is distributed in an arc shape at equal distances on the circumferential outer wall of the ceramic reinforcement column 3003. The inner walls on both sides of the assembly groove 3002 are provided with rectangular grooves 6002 distributed at equal distances. The circumferential outer wall of the ceramic reinforcement column 3003 and the two sides of the assembly groove 3002 form a filling gap, and the filling gap and the interior of the arc groove 6003 and the rectangular groove 6002 are filled with adhesive 6001, which can tightly bond the ceramic reinforcement column 3003 to the interior of the assembly groove 3002.

[0059] In order to improve the compressive bearing capacity of the entire fiberboard, refer to Figure 2The reinforcing component 5 includes an arc frame 5001 arranged on the top of the first layer plate 1, and the circumferential outer wall of the arc frame 5001 is fixedly connected with a diagonal support portion 5005. The cross-section of the diagonal support portion 5005 is in the shape of a circular tube. There are two groups of diagonal support portions 5005, which are respectively arranged on both sides of the arc frame 5001. The two groups of diagonal support portions 5005 and the circumferential outer wall of the arc frame 5001 are in contact with the bottom outer wall of the second layer plate 2. Since the arc frame 5001 arranged between the first layer plate 1 and the second layer plate 2 is in an arched structure, it can effectively disperse the vertical pressure. When pressure acts on the top of the arc frame 5001, it will be converted into downward pressure and outward thrust. This outward thrust is transmitted to the bottom block 5002, so that the pressure is evenly distributed.

[0060] In order to ensure the support capacity of the bottom of the arc frame 5001, refer to Figure 2 Bottom blocks 5002 are provided at both ends of the arc frame 5001. The cross section of the bottom block 5002 is semicircular. A horizontal plate 5007 is fixedly connected to the circumferential outer wall of the bottom block 5002. One end of the horizontal plate 5007 away from the bottom block 5002 is fixedly connected to the other bottom block 5002. The cross section of the bottom block 5002 is semicircular, which can disperse the pressure again.

[0061] In order to improve the overall strength of the fiberboard, refer to Figure 2 The top outer wall of the horizontal plate 5007 is fixedly connected to the support plate 5006, and the top of the support plate 5006 is fixedly connected to the inclined plate 5008. There are two groups of inclined plates 5008. One end of the two groups of inclined plates 5008 away from the top of the support plate 5006 is fixedly connected to the circumferential inner wall of the arc frame 5001. The cross-sections of the two groups of inclined plates 5008 and the support plate 5006 are Y-shaped. After being dispersed, a part of the force acting on the arc frame 5001 in the vertical direction will be transmitted to the inclined plate 5008 and the support plate 5006, and transmitted to the two The pressure on the inclined plate 5008 will be decomposed into horizontal forces and forces in the direction of the inclined plate 5008. The horizontal forces will cancel each other out. When the force in the direction of the inclined plate 5008 is transmitted to the support plate 5006, it will be decomposed into vertical downward and horizontal forces. The horizontal forces will continue to cancel each other out, while the vertical forces will be borne by the support plate 5006. As a result, the forces acting on the inclined plate 5008 and the support plate 5006 will flow from the top of the inclined plate 5008 to the bottom of the support plate 5006 like a fluid, thereby playing a good role in strengthening support.

[0062] In order to make the arc frame 5001 and the first layer board 1 fastened together, refer to Figure 2A second card slot 5004 is provided on the top outer wall of the first layer board 1, and a card plate 5003 is clamped inside the second card slot 5004. The top of the card plate 5003 contacts the bottom outer wall of the bottom block 5002. By clamping the card plate 5003 inside the second card slot 5004, the arc frame 5001 can be quickly and stably installed.

[0063] In order to facilitate the quick connection between the first layer board 1 and the second layer board 2, refer to Figure 9-10 The clamping assembly 8 includes a third clamping groove 8001 provided on the outer wall of the top of the vertical plate 7, the cross section of the third clamping groove 8001 is an isosceles trapezoid, the bottom inner wall of the third clamping groove 8001 is provided with a fourth clamping groove 8002, the interior of the third clamping groove 8001 is clamped with a locking block 8003, the specification of the locking block 8003 is smaller than that of the third clamping groove 8001, and one end of the locking block 8003 is provided with an extension portion, which is clamped in the interior of the fourth clamping groove 8002. When the first layer board 1 and the second layer board 2 need to be combined and bonded, firstly, glue is applied to the bonding surface of the first layer board 1 and the second layer board 2, and glue is injected into the third clamping groove 8001 and the fourth groove, and then the staff locks the bottom of the second layer board 2. The tightening block 8003 is aligned with the third slot 8001 at the top of the first layer of board 1. Since the specification of the locking block 8003 is smaller than that of the third slot 8001, the staff can easily clamp the locking block 8003 in the third slot 8001 to make the bonding surface of the first layer of board 1 and the second layer of board 2 fit together. When the first layer of board 1 and the second layer of board 2 fit together, the staff pushes the second layer of board 2. When the second layer of board 2 is subjected to external thrust, it will drive the locking block 8003 to move horizontally together. At this time, the locking block 8003 will move in the third slot 8001 until the locking block 8003 is clamped in the third slot 8001 and cannot move. At this time, the first layer of board 1 and the second layer of board 2 are locked and fixed.

[0064] Reference Figure 1-Figure 11 This embodiment also includes a guide channel 9 on the bottom inner wall of the third card slot 8001, and the end of the guide channel 9 away from the third card slot 8001 is connected to the fourth card slot 8002. During the horizontal movement of the locking block 8003, the glue remaining in the fourth card slot 8002 can be squeezed into the guide channel 9. The glue will be continuously squeezed into the second matching groove 11 at the bottom of the locking block 8003 through the guide channel 9, so that the locking block 8003 and the third card slot 8001 are tightly bonded.

[0065] In order to ensure the firmness of the bonding between the locking block 8003 and the third slot 8001, refer to Figure 8The guide channel 9 includes a liquid outlet 9001, a curved pipe portion 9002 and a liquid inlet 9003. The curved pipe portion 9002 is located in the middle of the liquid outlet 9001 and the liquid inlet 9003. The liquid outlet 9001 is connected to the third card slot 8001, and the liquid inlet 9003 is connected to the fourth card slot 8002. The inner diameter of the curved pipe portion 9002 is smaller than the inner diameters of the liquid outlet 9001 and the liquid inlet 9003. The inner diameter of the curved pipe portion 9002 is smaller than the inner diameters of the liquid outlet 9001 and the liquid inlet 9003, which can effectively avoid a large amount of glue residue in the curved pipe portion 9002.

[0066] In order to ensure that the locking block 8003, the extension part and the third slot 8001 and the fourth slot 8002 are tightly bonded and fixed, refer to Fig.11 The bottom outer wall of the locking block 8003 is provided with second matching grooves 11 distributed at equal distances, and the second matching grooves 11 include an oblique groove 1101 and a groove 1102, and the oblique groove 1101 is connected to the groove 1102. The outer wall of one side of the extension portion is provided with first matching grooves 10 distributed at equal distances, and the cross-section of the first matching groove 10 is V-shaped. The glue will be continuously squeezed into the second matching groove 11 at the bottom of the locking block 8003 through the guide channel 9, thereby realizing the bonding and fixation between the locking block 8003 and the third card slot 8001, and the groove 1102 in the second matching groove 11 can prevent the glue from flowing back into the inside of the guide channel 9. At the same time, the glue located in the fourth card slot 8002 enters the inside of the first matching groove 10, so that it can be tightly bonded to the extension portion.

[0067] Working principle: During the use of the fiberboard, the wear-resistant coating 3001 located on the top of the second layer 2 will first come into contact with objects, the ground, etc. Since the wear-resistant coating 3001 is made of ceramic granular material, its hardness is much higher than that of ordinary metal surfaces, so it can resist the impact of high-speed particles or fluids without being worn. When the board is used in an environment with very severe wear, even if the wear-resistant coating 3001 is completely worn out, the top of the ceramic reinforcing column 3003 located in the assembly groove 3002 will completely leak out. The ceramic reinforcing column 3003 has good smoothness on its surface, which can reduce the friction between it and the object, thereby effectively reducing wear. In addition, the top of the ceramic reinforcing column 3003 is higher than the top of the second layer 2, so it effectively avoids The second layer 2 is prevented from directly contacting with an object and causing aggravated wear, and a good protective effect is provided for the entire fiberboard. The ceramic reinforcing columns 3003 are evenly distributed in the assembly groove 3002 at the top of the second layer 2. Since the ceramic reinforcing columns 3003 have good hardness, they can not only play a wear-resistant role, but also strengthen the second layer 2, thereby ensuring the strength of the entire fiberboard. Since the arc frame 5001 arranged between the first layer 1 and the second layer 2 is an arched structure, the vertical pressure can be effectively dispersed. When the pressure acts on the top of the arc frame 5001, it will be converted into downward pressure and outward thrust. This outward thrust is transmitted to the bottom block 5002, so that the pressure can be evenly distributed. At the same time, the cross section of the bottom block 5002 is semicircular, which can disperse the pressure again, further improving the compression resistance of the entire arc frame 5001, and the diagonal bracing parts 5005 arranged on both sides of the top of the arc frame 5001 can expand the contact area with the bottom of the second layer 2, so as to avoid the situation that the top of the arc frame 5001 is subjected to excessive pressure. At the same time, the cross section of the diagonal bracing part 5005 is tubular, which is composed of continuous annular cross sections. This continuity helps to resist external pressure, so that the pressure can be evenly transmitted to the entire structure instead of concentrating on a certain point, thereby ensuring that the diagonal bracing part 5005 has good compression resistance and support ability, and the dispersed part of the force acting on the arc frame 5001 in the vertical direction will be transmitted to the diagonal bracing part 5005. The pressure transmitted to the two groups of inclined plates 5008 will be decomposed into horizontal forces and forces in the direction of the inclined plates 5008. The horizontal forces will offset each other. When the forces in the direction of the inclined plates 5008 are transmitted to the support plates 5006, they will be decomposed into vertical downward and horizontal forces. The horizontal forces will continue to offset each other, while the vertical forces will be borne by the support plates 5006. As a result, the forces acting on the inclined plates 5008 and the support plates 5006 will flow from the top of the inclined plates 5008 to the bottom of the support plates 5006 like a fluid, thereby playing a good role in strengthening and supporting. Moreover, most areas of the entire reinforcing component 5 are hollowed out, which ensures that the strength of the entire fiberboard is improved while also reducing its overall thickness, meeting people's usage needs.When the first layer board 1 and the second layer board 2 need to be combined and bonded, firstly, glue is applied to the bonding surfaces of the first layer board 1 and the second layer board 2, and glue is injected into the third card slot 8001 and the fourth slot. Then, the staff aligns the locking block 8003 at the bottom of the second layer board 2 with the third card slot 8001 at the top of the first layer board 1. Since the specification of the locking block 8003 is smaller than that of the third card slot 8001, the staff can easily clamp the locking block 8003 in the third card slot 8001 to make the bonding surfaces of the first layer board 1 and the second layer board 2 fit together. When the first layer board 1 and the second layer board 2 fit together, the staff pushes the second layer board 2. When the second layer board 2 is subjected to external thrust When the locking block 8003 moves horizontally, the locking block 8003 moves in the third slot 8001 until the locking block 8003 is clamped in the third slot 8001 and cannot move. At this time, the first layer board 1 and the second layer board 2 are locked and fixed. In the process of horizontal movement of the locking block 8003, the glue remaining in the fourth slot 8002 can be squeezed into the guide channel 9. The glue will be continuously squeezed into the second matching groove 11 at the bottom of the locking block 8003 through the guide channel 9, thereby achieving full bonding and fixing between the locking block 8003, the extension block and the third slot 8001 and the fourth slot 8002 through glue.
