Therefore, they are widely used in the fields of furniture, construction, decoration, etc. However, solid wood materials have some inherent disadvantages, and the most prominent problem is that they are prone to bending and deformation. When solid wood materials are affected by environmental factors such as humidity and temperature, they are prone to expansion and contraction, resulting in the bending and deformation of the boards. In addition, long-term exposure to heavy pressure or improper use may also cause the solid wood boards to bend. Such deformation not only affects the beauty of solid wood products, but also may affect their use functions and structural stability, and even may lead to potential safety hazards.

However, these methods often increase the cost and have limited effects. Summary of the Utility Model

There are a total of four reinforcing ribs, up, down, left, and right, and adjacent two reinforcing ribs are detachably connected; there are a total of four border woods, up, down, left, and right, and the adjacent reinforcing ribs and border woods inside and outside are detachably connected.
[0007] Preferably, the reinforcing ribs are aluminum alloy reinforcing ribs. The reinforcing ribs are made of a mixed material of aluminum alloy and solid wood, are of a hollow structure, and are provided with air holes on the side facing the core board. A desiccant packet is placed in the hollow structure of the reinforcing ribs.
[0008] Preferably, insertion plates are vertically arranged on the reinforcing ribs, and the border woods are provided with slots for the insertion plates to be inserted into.
[0009] Preferably, after the longitudinal and transverse reinforcing ribs are spliced, they are connected by corner brackets. The corner brackets include flat plates and vertical plates vertically connected to the flat plates. A plurality of fasteners are vertically and horizontally arranged on the flat plates and the vertical plates respectively, and the fasteners are connected to the reinforcing ribs.
[0010] Preferably, the edge parts of the frame wood and the veneer are sealed with PUR glue and PVC edge banding tape.
