Description

Technical Field

[0001] This utility model relates to the field of plywood technology, and in particular to an orthogonal plywood. Background Technology

[0002] Cross-laminated plywood (CLP) is a solid wood panel made by orthogonally stacking timber and gluing it together. Its area and thickness can be customized as needed. This material has a variety of uses and can be used directly in large pieces as exterior walls, floors, etc. The manufacturing process of CLP involves orthogonally assembling at least three layers of solid lumber or structural composite material between the layers and pressing them together using structural adhesives, ultimately forming factory-prefabricated engineered wood products in the form of rectangular, straight, or flat panels.

[0003] When existing cross-laminated plywood is used for exterior walls or floors in buildings, it is often subject to accidental impacts. The simple plywood structure is easily damaged when subjected to external forces, and the inner layers are also prone to deformation and damage, thus affecting the long-term use of the plywood. To address this, we propose a new type of cross-laminated plywood. Utility Model Content

[0004] The main objective of this invention is to provide an orthogonal plywood board. An internal reinforcing structure is incorporated at the orthogonal plywood layer composed of a base layer, core layer, and outer layer. The outer layer is further reinforced with a hardwood board and rubber connecting plates as a buffer structure. The hardwood board provides elastic cushioning at the rubber connecting plates after impact, allowing the impact force to be transmitted and neutralized at the orthogonal plywood layer. Furthermore, I-shaped clamping strips composed of steel strips A, B, and diagonal steel plates are bonded and secured within the I-shaped clamping grooves of the base layer, core layer, and outer layer. When steel strips A, B, and the diagonal steel plates encounter external forces, the reinforced orthogonal plywood is less prone to damage, ensuring its long-term use and effectively solving the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An orthogonal plywood board includes a base layer, a core layer, an outer layer, an I-shaped waist groove, steel strip A, diagonal steel plates, steel strip B, triangular wooden strips, a core hole, a steel core strip, a rubber connecting plate, and a hardwood board. The base layer, core layer, and outer layer are bonded layer by layer in an orthogonal combination to form an orthogonal plywood. An I-shaped waist groove is formed through the outer surface of the base layer, core layer, and outer layer. Steel strip A, diagonal steel plates, and steel strip B are fitted into the I-shaped waist groove. Diagonal steel plates are symmetrically welded between steel strip A and steel strip B to form an I-shaped waist strip. A rubber connecting plate and a hardwood board are bonded layer by layer to the outer surface of the outer layer away from the core layer. A triangular wooden strip is inserted between the diagonal steel plates and steel strip A, and a core hole is formed in the middle of the triangular wooden strip. A steel core strip is inserted and bonded into the core hole.

[0007] Furthermore, the thickness of the rubber connecting plate is less than the thickness of the hardwood board;

[0008] By adopting the above technical solution, a thinner rubber connecting plate can be bonded between the hardwood board and the outer board layer as a buffer.

[0009] Furthermore, the cavity length of the core hole is the same as the strip length of the steel core strip, and the cavity length of the core hole is the same as the strip length of the triangular wooden strip;

[0010] By adopting the above technical solution, the steel core strip can be inserted into the core hole of the triangular wooden strip for support.

[0011] Furthermore, the length of the triangular wooden strip is the same as the length of the steel strip A;

[0012] By adopting the above technical solution, triangular wooden strips can be clamped and supported between the inclined steel plate and steel strip A.

[0013] Furthermore, the two sets of inclined steel plates are symmetrically welded in a triangle between steel strip A and steel strip B, with the corners of the inclined steel plates welded to the surface of steel strip B and the bottom of the inclined steel plates welded to the surface of steel strip A.

[0014] By adopting the above technical solution, the inclined steel plate can be fixed in a triangular shape between steel strip A and steel strip B for connection.

[0015] Furthermore, the thickness of the bottom plate layer, the core plate layer, and the outer plate layer is the same;

[0016] By adopting the above technical solution, the base plate layer, core plate layer and outer plate layer of the same thickness can be stacked and bonded layer by layer in an orthogonal combination manner.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides an internal reinforcement structure at the orthogonal plywood composed of a bottom layer, a core layer, and an outer layer, and uses a hardwood board and a rubber connecting plate as a buffer structure on the outside of the outer layer. The hardwood board can obtain elastic buffer at the rubber connecting plate after being impacted, and then the impact force is transmitted and offset at the orthogonal plywood composed of the bottom layer, the core layer, and the outer layer.

[0019] Furthermore, the I-shaped clamping strips composed of steel strip A, steel strip B, and diagonal steel plates are bonded and clamped in the I-shaped clamping grooves of the bottom plate layer, core plate layer, and outer plate layer. When steel strip A, steel strip B, and diagonal steel plates encounter external forces, the reinforced orthogonal plywood is not easily damaged, ensuring the long-term use of the orthogonal plywood.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-3As shown, an orthogonal plywood board includes a base layer 1, a core layer 2, an outer layer 3, an I-shaped interlocking groove 4, a steel strip A5, diagonal steel plates 6, steel strip B7, triangular wooden strips 8, core holes 9, steel core strips 10, a rubber connecting plate 11, and a hardwood board 12. The base layer 1, core layer 2, and outer layer 3 are bonded layer by layer in an orthogonal combination to form an orthogonal plywood board, and the outer surface of the base layer 1, core layer 2, and outer layer 3 is provided with an I-shaped interlocking groove 4. The I-shaped clamping groove 4 is fitted with steel strip plate A5, diagonal steel plate 6 and steel strip plate B7, and the diagonal steel plate 6 is symmetrically welded between steel strip plate A5 and steel strip plate B7 to form an I-shaped clamping strip. The outer plate layer 3 away from the core plate layer 2 is bonded with rubber connecting plate 11 and hardwood board 12 layer by layer. A triangular wooden strip 8 is inserted between the diagonal steel plate 6 and steel strip plate A5, and a core hole 9 is opened in the middle of the triangular wooden strip 8. A steel core strip 10 is inserted and bonded into the core hole 9.

[0026] The thickness of the rubber connecting plate 11 is less than the thickness of the hardwood board 12.

[0027] By adopting the above technical solution, the thinner rubber connecting plate 11 can be bonded between the hardwood board 12 and the outer board layer 3 as a buffer part.

[0028] Wherein, the cavity length of the core hole 9 is the same as the strip length of the steel core strip 10, and the cavity length of the core hole 9 is the same as the strip length of the triangular wooden strip 8;

[0029] By adopting the above technical solution, the steel core strip 10 can be inserted into the core hole 9 of the triangular wooden strip 8 for support.

[0030] The length of the triangular wooden strip 8 is the same as the length of the steel strip A5;

[0031] By adopting the above technical solution, the triangular wooden strip 8 can be clamped and supported between the inclined steel plate 6 and the steel strip A5.

[0032] The two sets of plates of the inclined steel plate 6 are symmetrically welded in a triangle between steel strip A5 and steel strip B7, and the corner of the inclined steel plate 6 is welded to the surface of steel strip B7, while the bottom of the inclined steel plate 6 is welded to the surface of steel strip A5.

[0033] By adopting the above technical solution, the inclined steel plate 6 can be fixed in a triangular shape between the steel strip A5 and the steel strip B7 for connection.

[0034] The bottom plate layer 1, the core plate layer 2, and the outer plate layer 3 have the same thickness.

[0035] By adopting the above technical solution, the bottom plate layer 1, core plate layer 2 and outer plate layer 3 of the same thickness can be stacked and bonded layer by layer in an orthogonal combination manner.

[0036] It should be noted that this utility model is an orthogonal plywood board. After setting I-shaped clamping grooves 4 in the board body of the bottom board layer 1, core board layer 2, and outer board layer 3, symmetrically welded diagonal steel plates 6 between steel strip A5 and steel strip B7 to form I-shaped clamping strips. Then, steel core strip 10 is inserted into the core hole 9 of triangular wooden strip 8 for reinforcement and support. At the same time, triangular wooden strip 8 can be inserted between diagonal steel plates 6 and steel strip A5 for adhesive support. At this time, the bottom board layer 1, core board layer 2, and outer board layer 3 are bonded layer by layer in an orthogonal combination to form an orthogonal plywood. Then, the outer surface of the outer board layer 3 can be connected to hardwood boards 12 by rubber connecting plates 11. When the orthogonal plywood needs to be used as an exterior wall or floor slab, the orthogonal plywood can be fixed to the fixing point of the exterior wall or floor slab with one side of the bottom board layer 1. 3. With one side of the rubber connecting plate 11 and the hardwood board 12 as the exposed surface, when the orthogonal plywood is subjected to an external impact, the hardwood board 12 can obtain elastic buffer at the rubber connecting plate 11 after the impact. Then, the impact force is transmitted and offset at the orthogonal plywood composed of the bottom plate layer 1, the core plate layer 2 and the outer plate layer 3. The I-shaped clamping groove 4 of the bottom plate layer 1, the core plate layer 2 and the outer plate layer 3 is glued and clamped in the groove by the I-shaped clamping strip composed of steel strip A5, steel strip B7 and diagonal steel plate 6. When the steel strip A5, steel strip B7 and diagonal steel plate 6 are subjected to external force, the reinforced orthogonal plywood is not easily damaged, ensuring the long-term use of the orthogonal plywood. At the same time, if the hardwood board 12 is damaged, it can be forcibly removed from the rubber connecting plate 11, and then a new hardwood board 12 can be used to re-glue and clamp at the rubber connecting plate 11.
