Description

Technical Field

[0001] The utility model relates to the technical field of plates, in particular to an anti-deformation composite plate. Background Art

[0002] Wood-based panels are essential raw materials in industry and life, and are used to manufacture industrial products, furniture, and building decoration materials. Wood-based panels are made by mechanically separating wood into unit materials and then applying adhesives to composite materials. As people's living standards improve, the consumption of wood-based panels tends to retain solid wood straight-jointed panels, solid wood integrated materials, blockboards, and plywood products that have high wood properties and are more environmentally friendly. However, the unique properties of wood determine that these types of panels will produce internal stress variations. When the internal stress exceeds a certain level, the panel will bend, which will eventually affect the flatness and use effect of the entire panel. On the other hand, when the ambient temperature and humidity change, the panel will expand and contract with heat, shrink with drying, and expand with wetness, causing periodic changes in the internal stress of the panel, resulting in overall or partial deformation of the panel.

[0003] However, the existing wood composite boards are generally made of pressed wood fibers, and do not have strong impact resistance and strength. When the installed boards are overloaded, the composite boards will be overstressed, resulting in bending, deformation and breakage. Utility Model Content

[0007] A plurality of connection components are connected between the upper plate and the bottom plate, and the plurality of connection components respectively penetrate through a plurality of circular holes on the middle plate;

[0008] A plurality of transverse anti-deformation ribs are arranged side by side, and the transverse anti-deformation ribs are arranged between the upper plate and the middle plate, and a plurality of transverse rib grooves are provided at the lower end of the upper plate and the upper end of the middle plate;

[0009] A plurality of longitudinal anti-deformation ribs are arranged side by side, and the longitudinal anti-deformation ribs are arranged between the middle plate and the bottom plate. A plurality of longitudinal rib grooves are provided at the lower end of the middle plate and the upper end of the bottom plate.

[0010] Preferably, the connecting assembly includes a plug, a sleeve and a plurality of clamping parts, the plug and the sleeve are respectively connected to the bottom plate and the upper plate, the plurality of clamping parts are arranged on the inner side of the sleeve along a circular array, the clamping parts include an elastic metal sheet connected to the inner wall of the sleeve and a wedge-shaped block arranged at the end of the elastic metal sheet, and a circle of annular grooves are opened on the outer wall of the plug.

[0011] Preferably, at least one set of connecting components is arranged at the intersection of the transverse anti-deformation ribs and the longitudinal anti-deformation ribs, and circular holes for the connecting components to pass through are opened on the transverse anti-deformation ribs and the longitudinal anti-deformation ribs.

[0012] Preferably, the outer surface of the upper plate is provided with a flame retardant layer.

[0013] Preferably, a waterproof layer is provided on the outer surface of the flame retardant layer.

[0014] Compared with the prior art, the utility model has the following beneficial technical effects:

[0015] 1. Multiple transverse anti-deformation ribs and multiple longitudinal anti-deformation ribs are clamped inside the plate, thereby improving the plate's resistance to deformation and extending the service life of the plate.

[0016] 2. The plug post is inserted into the inner side of the sleeve, and the plug post squeezes multiple wedge blocks away from each other. When the annular groove moves to the position of the wedge block, the end of the wedge block is inserted into the inner side of the annular groove, thereby realizing a fixed connection between the plug post and the sleeve. The arrangement of the above structure can greatly improve the stability of the connection between multiple plates, making it less likely for the plates to become hollow, debonded, or cracked.
