Description

Technical Field

[0001] This utility model relates to the field of flame-retardant plywood technology, and in particular to a flame-retardant and deformation-resistant plywood. Background Technology

[0002] Flame-retardant plywood is a three- or multi-layered board material made by rotary cutting logs into veneers or slicing timber into thin sheets, treating the veneers with flame retardants, and then gluing them together with adhesives. It usually uses an odd number of veneer layers, with the fiber directions of adjacent veneers glued perpendicular to each other. It is made from beech plywood as raw material and is produced through a series of technologies and processes, taking into full account the smoke density and toxic gas indicators of fire hazards.

[0003] According to the announcement number CN223013423U, a bidirectional anti-deformation plywood is proposed. Through the cooperation of a plywood substrate, a second anti-deformation frame plate, a plywood upper panel, a protective frame, and bidirectional anti-deformation components, the plywood substrate is placed on top of the first anti-deformation frame plate. The protective frame is then secured to the periphery of the plywood substrate and the first anti-deformation frame plate using positioning blocks. The second anti-deformation frame plate is then assembled on top of the plywood substrate and secured with the positioning blocks. Finally, the plywood upper panel and plywood lower back panel are respectively secured to the top and bottom of the assembled plywood substrate, and the connecting parts are bonded and pressed tightly. Finally, rubber pillars and limiting discs fix and restrict the plywood, improving the strength and bidirectional anti-deformation capability of the plywood structure. The waterproof and flame-retardant layers further enhance the waterproof and flame-retardant effects of the plywood, ensuring its service life.

[0004] Existing flame-retardant plywood is typically reinforced by incorporating an internal anti-deformation frame. This design aims to improve the overall stability and resistance to deformation of the plywood. Specifically, the anti-deformation frame is bonded to the inner layer of the flame-retardant plywood with adhesive, so that they can jointly resist deformation when subjected to external forces. However, this traditional structure has obvious limitations, namely, the anti-deformation frame is made of a different material than the flame-retardant plywood itself, resulting in limited bonding strength between the two. Especially under long-term dynamic loads or temperature changes, delamination is likely to occur.

[0005] Therefore, there is an urgent need to provide a flame-retardant and deformation-resistant plywood to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a flame-retardant and deformation-resistant plywood.

[0009] The above technical solution uses a first vertical reinforcing strip and a second vertical reinforcing strip to splice and reinforce the first panel and the second panel.

[0010] The present invention is further configured such that: the interior of the second docking frame is provided with four first mounting holes, and the interior of the first docking frame is provided with four second mounting holes.

[0012] The present invention is further configured such that: an installation sleeve is fitted inside the first mounting hole, and an installation bolt is fitted inside the second mounting hole, wherein the outside of the installation bolt is fixed to the internal thread of the installation sleeve.

[0013] Using the above technical solution, mounting bolts and mounting sleeves are used to fix the first panel and the second panel.

[0014] The present invention is further configured such that: the reinforcing mechanism includes a reinforcing panel disposed between the first panel and the second panel, the top end of the reinforcing panel is fixed with a first transverse reinforcing strip distributed at intervals, and the bottom end of the reinforcing panel is fixed with a second transverse reinforcing strip distributed at intervals.

[0015] Through the above technical solution, the reinforced panel, the first transverse reinforcing strip, and the second transverse reinforcing strip are processed and produced as a single unit, which improves the strength of the flame-retardant plywood.

[0016] The present invention is further configured such that: a plurality of first short flame-retardant plywoods are bonded and installed on one side of the first transverse reinforcing strip, and a first long flame-retardant plywood is bonded and fixed between the plurality of first short flame-retardant plywoods.

[0017] Through the above technical solution, the first short flame-retardant plywood and the first long flame-retardant plywood are interlaced and bonded to the first transverse reinforcing strip, which improves the bonding force between the two.

[0018] The present invention is further configured such that: a plurality of second short flame-retardant plywoods are bonded and installed on one side of the second transverse reinforcing strip, and a second long flame-retardant plywood is bonded and fixed between the plurality of second short flame-retardant plywoods.

[0019] Through the above technical solution, the second short flame-retardant plywood and the second long flame-retardant plywood are interlaced and bonded to the second transverse reinforcing strip, and their directions are perpendicular to each other, which improves the strength of the flame-retardant plywood.

[0020] The beneficial effects of this utility model are as follows: 1. This utility model, by providing a reinforcement mechanism and setting reinforcement strips on both sides of the reinforcement panel, thereby interlacing and bonding them with the flame-retardant plywood, improves the load-bearing capacity and impact resistance of the entire flame-retardant plywood structure, enabling the flame-retardant plywood to maintain a good shape when facing various external forces, greatly reducing the risk of deformation and damage, and extending its service life. 2.
