Problems solved by technology

However, in actual production, the production cost of heat treatment is high, and it will reduce the mechanical properties of the material, so this solution can only be applied to the product combination solution where the base material is a whole piece of wood material
When the material is a small material, one cannot carry out batch heat treatment, such as finger jointing into a whole material and then heat treatment will put forward higher requirements for the adhesive, thus further increasing the manufacturing cost; The mechanical strength of the multi-layer structure comes from the supporting force between the layers, so the decline in the mechanical properties of the single-layer structure has a greater impact on the overall mechanical properties

Abstract

The invention discloses a manufacturing method of a multilayered-frame solid wood floor, which comprises a raw material production step comprising a surface plate production working procedure, a balance layer veneer production working procedure and a core plate narrow material production working procedure; a raw material humidifying step comprising a surface plate humidifying working procedure and a balance layer veneer humidifying working procedure; a core plate production step, wherein core plate narrow materials are firstly spliced in the length direction to manufacture core plate middle long materials, then a first humidifying working procedure is carried out, the core plate middle long materials subjected to humidification are spliced in the width direction to manufacture a core plate, and then a second humidifying working procedure is carried out; a balance layer veneer and surface plate pressing step, wherein the stacking sequence of raw materials is a surface plate, a balance layer veneer, the core plate, another balance layer veneer and another surface plate, two adjacent right-angle sides are taken as a benchmark for alignment, and the pressing mode is to carrying out cold pressing firstly and carry out hot pressing secondly; and an aging step, wherein the floor is placed at room temperature for natural conditioning. The multilayered-frame solid wood floor has the characteristics of good mechanical strength, good stability and low manufacturing cost.

Description

technical field [0001] The invention relates to the field of floors and floor processing, in particular to a solid wood multi-layer frame floor and a method thereof. Background technique [0002] Solid wood multi-layer composite flooring is the mainstream environment-friendly product in the flooring market at present. It has various forms and rich types of structures. The frame-type composite floor with the joint board as the core board is made of waste materials after wooden flooring or other wood products are processed. Moreover, the frame-type composite floor has improved the stability of the product through its multi-layer and criss-cross blanking method, the constraints between the layers, and the symmetrical arrangement in the thickness direction. For example, a solid wood composite floor is disclosed in patent 200620139748.0, which has five layers Structure, the grain arrangement direction of the wood material of the first layer of the wood sheet layer, the third lay...
