Arch camber prevention floor made of elastic materials

Abstract

The invention provides an arch camber prevention floor made of elastic materials. The arch camber prevention floor comprises wood board blocks and keels, wherein a transverse inserted tenon, a transverse slot, bottom surface slots and bottom surface accommodating grooves are formed in each wood board block; the transverse inserted tenon on each wood board block is inserted into the transverse slot of the other wood board block adjacent to the wood board block in a sleeved manner; each keel is made of arc-shaped elastic pieces, square blocks and inserted ribs; the square blocks are welded and fixed on two sides of each arc-shaped elastic piece; the inserted ribs are formed on the square blocks; two inserted ribs are respectively inserted into the bottom surface slots formed in two adjacent wood board blocks in the sleeved manner; the arc-shaped elastic pieces are placed in the bottom surface accommodating grooves of each wood board block; the left surface and the right surface of each wood board block are coated with elastic plastic layers. The arch camber prevention floor provided by the invention can effectively prevent arch camber and deformation of the wood board blocks, and reduce the clearance between each two adjacent wood board blocks.

Description

Technical field: [0001] The invention relates to the field of floor technology, and more specifically relates to a wooden floor using an aluminum alloy keel. Background technique: [0002] See figure 1 As shown, there is a kind of wooden floor on the market at present, which is composed of wooden board A1 and keel A2. The horizontal tenon A11 and the horizontal slot A12 are formed on the wooden board A1. In the transverse slot A12 of another wooden board A1, a bottom slot A13 is formed on the bottom surface of the wooden board A1, and the bottom slot A3 is inserted into the rib A21 on the keel A2. Its disadvantages are: 1. Wooden boards have the characteristics of wet expansion and dry shrinkage. When wooden boards are wet and swollen, a large transverse stress will be generated between two adjacent wooden boards. This stress acts on the wooden boards. It is easy to make the wooden board arch and deform. 2. When the wooden board shrinks, there will be a large gap between ...

Its disadvantages are: 1. Wooden boards have the characteristics of wet expansion and dry shrinkage. When the wooden boards are wet and swollen, a large transverse stress will be generated between two adjacent wooden boards. This stress acts on the wooden boards. It is easy to cause the wooden board to arch and deform

2. When the wooden board shrinks, there will be a large gap between two adjacent wooden boards
