Abstract
Description
Technical Field
[0001] This utility model relates to the field of plywood technology, specifically to a high-strength anti-collision plywood. Background Technology
[0002] Plywood is a commonly used material in furniture making and one of the three major types of engineered wood products. It is also used in aircraft, ships, trains, automobiles, construction, and packaging. A set of veneers is usually glued together with adjacent layers of wood grain perpendicular to each other. Typically, the face veneer and inner veneer are symmetrically arranged on both sides of the core layer. The plywood blank, made by gluing veneers and arranging them in a cross-grain pattern, is pressed under heated or unheated conditions. The number of layers is generally odd, but there are a few with an even number. The physical and mechanical properties in the longitudinal and transverse directions are relatively similar. Common types of plywood include three-ply and five-ply. Plywood can improve the utilization rate of wood and is a major way to save wood.
[0003] Plywood has a wide range of applications. In addition to furniture making, it can also serve as a protective material in some situations. Furthermore, in the production of wooden crates, plywood needs to have good impact resistance to ensure the protection of the contents. However, existing plywood, after evaporation and drying, relies solely on the adhesive between the layers for its toughness. This type of plywood cannot withstand significant external impacts and lacks inherent toughness, making it susceptible to bending. Therefore, it is only suitable for furniture making. To address this, we propose a high-strength impact-resistant plywood. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a high-strength anti-collision plywood, which solves the problems mentioned in the background section.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-strength anti-collision plywood, comprising two outer panels, a support sleeve fixedly supporting the two outer panels, a support frame fixedly supporting the two outer panels, a PP skeleton fixedly fitted inside the support frame, and mutually fitting support ridges fixedly supporting the two outer panels.
[0006] Optionally, the support sleeve is located outside the support frame, and the outer side of the support sleeve and the outer side of the outer panel are located on the same vertical plane.
[0007] Optionally, the vertical cross-section of the support block is an equilateral triangle, the interior of the support block is a hollow equilateral triangle, and the outer side of the support block is attached to the inner side of the outer panel.
[0008] Optionally, the PP skeleton is in the form of a grid, the supporting ridge is located inside the grid of the PP skeleton, and the vertical cross-section of the PP skeleton is circular.
[0009] Optionally, the height of the PP skeleton is the same as the height of the supporting edge block, and the height of the PP skeleton is the same as the height of the supporting frame.
[0010] This utility model provides a high-strength anti-collision plywood, which has the following beneficial effects:
[0011] 1. This high-strength anti-collision plywood features two outer panels with a support frame fixed between them. A mesh-like PP skeleton is also fixed inside the support frame, effectively stabilizing the entire plywood and preventing deformation from excessive external forces. Additionally, the support ribs inside the PP skeleton, located between the two outer panels, effectively buffer point impacts, preventing direct punctures and providing the plywood with a certain degree of impact resistance while effectively reducing overall weight.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a high-strength anti-collision plywood, including two outer panels 1, a support sleeve 2 fixedly supported between the two outer panels 1, a support frame 3 fixedly supported between the two outer panels 1, a PP skeleton 4 fixedly fitted inside the support frame 3, and mutually fitting support ribs 5 fixedly supported between the two outer panels 1.
[0019] The support sleeve 2 is located outside the support frame 3. The outer side of the support sleeve 2 and the outer side of the outer panel 1 are on the same vertical plane. The support frame 3, together with the support sleeve 2, can stabilize the compressive structure in the middle and effectively play a role in improving the strength.
[0020] The vertical cross-section of the support block 5 is an equilateral triangle, the interior of the support block 5 is a hollow equilateral triangle, and the outer side of the support block 5 is attached to the inner side of the outer panel 1. The triangular arrangement of the support block 5 can effectively assist in unloading force and effectively protect against impact. Even if the impact force is not completely protected, the inclined surface of the support block 5 will guide the unloading force and effectively protect the back of the plate.
[0021] The PP skeleton 4 is grid-shaped, and the supporting blocks 5 are located inside the grid of the PP skeleton 4. The vertical cross-section of the PP skeleton 4 is circular. The grid setting of the PP skeleton 4 can transmit external forces in a comprehensive manner, avoid overall tilting, and effectively improve the impact resistance of the board.
[0022] The height of PP frame 4 is the same as the height of support block 5, and the height of PP frame 4 is the same as the height of support frame 3. Compared with traditional plywood used for furniture, this type of plywood is more convenient for use in the making of wooden boxes, door and window protection and other scenarios.
[0023] In summary, when this high-strength anti-collision plywood is used, firstly, during daily use, when the plywood is impacted by external forces, the impact is transmitted through the outer panel 1 to the inner PP frame 4, causing the PP frame 4 to deform. The integrated design and toughness of the PP frame 4 will transmit the impact force outward, thus preventing the board from breaking due to a large impact force in a small area. The impact force that the board can withstand is effectively improved. At the same time, when the outer side of the outer panel 1 is subjected to point impact force, the support edge block 5 will become the most likely stress point. The triangular design of the support edge block 5 can effectively assist in dissipating the force and effectively protect against impact. Even if the impact force is not completely blocked, the inclined surface of the support edge block 5 will guide the force dissipation, effectively protecting the back of the board.
