Double-keel decorative plate

Abstract

A double-keel decorative plate comprises two neighboring wood blocks. A keel is composed of a T-shaped main rib and auxiliary ribs, which are formed on a square block; the main rib and the auxiliary ribs are inserted inside a main rib slot and auxiliary rib slots in the wood blocks in a matched mode; keel slots are formed in the T-shaped main rib; an elastic keel is a hollow elastic body, and elastic keel tenons are formed on the opening-type bottom edge of the elastic keel and inserted inside the keel slots; main rib transverse gaps and auxiliary rib gaps are retained between the main rib and the wood blocks as well as the auxiliary rib gaps and the wood blocks; the top end surface of the elastic keel is exposed out of the surfaces of the wood blocks, and the two neighboring wood blocks are pressed onto the elastic keel. The double-keel decorative plate can effectively avoid arching and deformation of the wood blocks and guarantee that contraction gaps seen from the surfaces of the wood blocks is relatively small.

Description

Technical field: [0001] The invention relates to the technical field of decorative panels, in particular to a decorative panel with combined keels. Background technique: [0002] Such as figure 1 As shown, there is currently a floor on the market, its two adjacent wooden boards A1 are connected together through the yin and yang groove A13 and the keel A2, the keel A2 has the main reinforcement A21 and the auxiliary reinforcement A22, the main reinforcement A21 and the auxiliary reinforcement A22 are inserted into the In the matching main rib slot A11 and auxiliary rib slot A12 on the wooden board A1, its disadvantages are: 1. When the wooden board is wet and swollen, a large transverse stress will be generated between two adjacent wooden boards , this stress is likely to cause arching and deformation of the wooden board. 2. When the wood boards are cold-shrinked, it is easy to see a large shrinkage gap between two adjacent wood boards on the surface of the wood boards. I...

[0002] like figure 1 As shown, there is currently a floor on the market, its two adjacent wooden boards A1 are connected together through the yin and yang groove A13 and the keel A2, the keel A2 has the main reinforcement A21 and the auxiliary reinforcement A22, the main reinforcement A21 and the auxiliary reinforcement A22 are inserted into the In the matching main rib slot A11 and auxiliary rib slot A12 on the wooden board A1, its disadvantages are: 1. When the wooden board is wet and swollen, a large transverse stress will be generated between two adjacent wooden boards , this stress is easy to cause the arching deformation of the wooden board

2. When the wood boards are cold-shrinked, it is easy to see a large shrinkage gap between two adjacent wood boards on the surface of the wood boards
