Problems solved by technology

[0003] However, since the panel of the finger-jointed board is a vertical strip structure, the static bending strength and elastic modulus of the board in the width direction are low, and it cannot be used as a floor substrate, especially a geothermal floor, which cannot meet its high deformation resistance. requirements

Embodiment 1

[0028] see Figure 1~5 As shown, a finger-jointed board floor comprises, from top to bottom, a decorative wood veneer 1, a wood veneer 2, a finger-joint board 3, a wood veneer and a decorative wood veneer,

[0029] The fiber length direction of the wood veneer is perpendicular to the length direction of the finger-jointed board, and the fiber length direction of the decorative wood veneer is perpendicular to the fiber length direction of the adjacent wood veneer;

[0030] The wood veneer is provided with at least 2 through slots 4 along the direction perpendicular to its fiber length direction, and the slots cut the wood veneer and go deep into the finger-jointed board; the slots go deep into the The depth of the finger joint plate accounts for 30% of the total thickness of the finger joint plate;

[0031] A molding strip 5 is arranged in the slot, and the surface of the molding strip is flush with the surface of the wood veneer.

[0032] The upper and lower wooden veneers o...

Abstract

The invention discloses a finger jointed plate floor, which comprises a decorating wood veneer, a wood veneer, a finger jointed plate, a wood veneer and a decorating wood veneer in sequence from the top to the bottom, wherein the fiber length direction of each wood veneer and the length direction of the finger jointed plate form a criss-cross structure; the fiber length direction of each wood veneer and the fiber length direction of an adjacent wood veneer form a criss-cross structure; each wood veneer is provided with at least two through caulking grooves along a direction vertical to the fiber length direction of the wood veneer; the caulking grooves cut each wood veneer and go deep into the finger jointed plate; panel strips are arranged in the caulking grooves; and the surfaces of the panel strips are flushed with the surfaces of the wood veneers. The floor has high deformation resistance and remarkable meaning; the static bending strength and elastic modulus of the floor in the width direction are 7-9 MPa and 7,000-9,000 GPa respectively; and an unexpected technical effect is achieved.

Description

technical field [0001] The invention relates to a floor, in particular to a finger-jointed board floor. Background technique [0002] The finger-joint board is made up of multiple wooden boards, and the upper and lower parts are no longer glued to the plywood. Since the vertical boards adopt a zigzag interface, which is similar to the cross-jointing of the fingers of two hands, it is called a finger-joint board. Finger-jointing is an integral part of the wood industry production process, which provides the wood industry with an efficient and viable production method that reuses waste and is environmentally responsible. Due to the elimination of some unwanted wood features, the strength and appearance quality of the wood have been improved, so it has been recognized by consumers, and it has also gained more benefits for the wood processing industry. [0003] However, since the panel of the finger-jointed board is a vertical strip structure, the static bending strength and el...
