Description

Technical Field

[0001] This utility model relates to the field of plywood technology, specifically to plywood with strong toughness and pressure resistance. Background Technology

[0002] Plywood is a sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets, and then gluing them together with adhesives. It typically uses an odd number of veneer layers, with the grain directions of adjacent layers perpendicular to each other. Plywood is a commonly used material in furniture making and one of the three major types of engineered wood products. A set of veneers is usually glued together with adjacent layers having their grain directions perpendicular to each other. The face veneer and inner veneer are usually symmetrically arranged on both sides of the core layer. To make plywood, the logs are first softened, then rotary cut into veneers of a certain thickness. After drying, finishing, and gluing, the veneers are assembled according to an alternating grain pattern. Finally, the adhesive is cured by hot pressing to form the board. Plywood improves wood utilization and is an important way to save timber. It has advantages such as high strength, structural stability, and resistance to deformation. Different numbers of layers and materials of plywood can meet diverse needs and are widely used in furniture manufacturing, construction and decoration, packaging, and shipbuilding. According to their uses, plywood can be divided into ordinary plywood and decorative veneer plywood. According to their materials, there are various types such as poplar plywood and birch plywood. However, when existing plywood is stored in warehouses for a long time, the bottom plywood is prone to breakage and damage due to the heavy load, resulting in production waste. At the same time, when the pressure on the plywood exceeds a certain range, the plywood is prone to deformation. Utility Model Content

[0008] Preferably, the waterproof layer is disposed on the top of the board, the fiberglass mesh is disposed on the bottom of the board, and the waterproof layer and the fiberglass mesh are symmetrically disposed on both sides of the board.

[0009] By adopting the above technical solution, the surface of board one can be waterproofed through a waterproof layer, thereby strengthening board one.

[0010] Preferably, the first reinforcing layer is embedded in the top of the second plate, and the end of the first reinforcing layer is connected to the bottom of the first glass fiber mesh.

[0011] By adopting the above technical solution, the compressive strength of the plywood is enhanced by the reinforcing layer 1, and the impact toughness of the plywood is increased by the fiberglass mesh.

[0012] Preferably, the surface of the third plate has a texture, and the texture of the third plate is interleaved with the texture of the second plate.

[0017] By adopting the above technical solution, the compressive strength and toughness of the third plate are increased by strengthening the second layer.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the plywood with strong toughness and compressive strength is:

[0019] 1. Fiberglass mesh fabric one and fiberglass mesh fabric two are set. Fiberglass mesh fabric one and fiberglass mesh fabric two are respectively set at the bottom of board one and the bottom of reinforcing layer one. Their fiber structure can absorb impact energy. When subjected to external impact, the mesh fabric can prevent crack propagation, so that the plywood can still maintain its integrity after being subjected to a certain deformation, reducing the risk of breakage.

[0020] 2. Reinforcing layer one and reinforcing layer two are set up to form a three-dimensional stress-bearing structure, which can effectively disperse external pressure. When the plywood is subjected to stacked weight or external compression, reinforcing layer one and reinforcing layer two work together to bear the force, which can withstand greater pressure and is not easy to break, thus improving the stability of the composite board.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-4 The present invention provides a technical solution: a plywood with strong toughness and pressure resistance, comprising a first board 10, a waterproof layer 20, a first fiberglass mesh 30, a second board 40, a first reinforcing layer 401, a second fiberglass mesh 50, a third board 60, and a second reinforcing layer 601.

[0031] The plywood is designed to improve its compressive strength, and the specific implementation method is as follows:

[0032] A waterproof layer 20 is attached to one side of the surface of board 10, and a fiberglass mesh 30 is attached to the surface of board 10. Board 40 is attached to the bottom of fiberglass mesh 30, and a reinforcing layer 401 is embedded in the surface of board 40. Fiberglass mesh 50 is attached to the bottom of reinforcing layer 401, and board 60 is attached to the bottom of fiberglass mesh 50. Reinforcing layer 601 is embedded in the surface of board 60. Board 10 and board 40 have textured surfaces, and their textures are interwoven. The waterproof layer 20 is located on top of board 10, and the fiberglass mesh... A 30 is set at the bottom of a 10-board, and a waterproof layer 20 and a fiberglass mesh 30 are symmetrically set on both sides of a 10-board. A 401 is embedded in the top of a 40-board, and the end of the 401 is connected to the bottom of the 30-board. A 60-board has a textured surface, and the texture of the 60-board is interlaced with the texture of the 40-board. A 601 is staggered with a 401, and the 601 is perpendicular to the 401. A 601 is embedded in the top surface of a 60-board, and the end of the 601 is connected to the bottom of the 50-board.

[0033] Waterproof coating is sprayed onto the surface of board 10 and allowed to solidify to form waterproof layer 20. The surface of board 40 is then machined using a milling machine, creating evenly spaced square grooves. Strips of board material are then glued to the interior of board 40, forming reinforcing layer 401. A press is then used to fix board 40 and reinforcing layer 401 together. Fiberglass cloth is then glued onto the surface of board 10, and board 40 is glued onto the other side of the fiberglass cloth. After the glue solidifies, the fiberglass cloth forms a fiberglass mesh 30. Finally, a press is used to fix all three together. The surface of plate 360 ​​is machined by a milling machine to create equally spaced square grooves. Then, strip-shaped plates are glued to the inside of plate 360, forming a reinforcing layer 2601. The plate 360 ​​and the reinforcing layer 2601 are then fixed together by a press. At this time, fiberglass cloth is laid on the bottom of plate 240 by glue, and then plate 360 ​​is bonded to the other surface of the fiberglass cloth, forming a fiberglass mesh fabric 250. When plate 360 ​​is placed, the reinforcing layer 2601 and the reinforcing layer 401 are placed alternately and perpendicularly. Finally, the entire assembly is pressed by a press to fix it.

[0034] When water falls on the surface of the waterproof layer 20, the waterproof layer 20 blocks the rainwater, allowing it to fall along its surface and preventing it from entering the surface of the board 10. At the same time, when the board 10 is impacted, it transmits the impact to the fiberglass mesh 30, which directly blocks the expansion of cracks, allowing the plywood to maintain its integrity after undergoing a certain deformation. Similarly, when the impact force is transmitted to the board 40, the fiberglass mesh 50 works in the same way. When a certain part of the plywood surface is under pressure, the external pressure can be effectively dispersed through the structure of the reinforcing layer 601 and the reinforcing layer 401, allowing the two reinforcing layers to work together to bear the force.

[0035] Working principle: When using this plywood with strong toughness and compressive strength, fiberglass mesh cloth 30, board 40 and reinforcing layer 401 are set to improve its compressive strength and increase its overall practicality.
