Solid wood composite floor and manufacturing method

technical field

The invention relates to a solid wood composite floor mainly produced by a laminated timber process structure and a manufacturing method, belonging to the technical field of flooring and processing.

Background technique

In the prior art, the structure of the solid wood composite floor is generally made of three or more layers through splicing and composite technology. The composite floor produced through the composite splicing processing technology has the cross-sectional fiber structure of wood on its long sides. When the groove is processed on the side, it will affect the quality of the processing and cause the rough surface of the groove, which is not only difficult to process into a lock, but also affects the installation of the floor and reduces the quality of the floor product. Glue or keeling will directly cause the increase of installation cost and the increase of indoor environmental pollution, which will affect the use effect.

Contents of the invention

The object of the present invention is to overcome the above-mentioned deficiencies and provide a solid wood composite floor with a new structure and a manufacturing method that integrates the laminated wood technology of wood processing and the structural composite technology.

type structure.

The base material blank board is formed by splicing at least two or more lamination boards through the ribs sandwiched between the two.

At least one layer of wood veneers whose fiber directions are at right angles are compounded on the upper and lower sides of the base material blank.

A layer of wood veneer is compounded on the base material blank board, and a decorative veneer is also compounded on the wood veneer.

Two layers of wood veneers are compounded under the base material blank, and the fiber directions of the two layers of wood veneers are at right angles.

A method for manufacturing the above-mentioned solid wood composite floor, which is to process the wood into pieces of laminated boards as the floor base material according to the laminated wood process, and then make the laminated boards into laminated strips, and mutually Spliced into floor base blanks, wood veneers with different fiber directions are compounded on the top and bottom of the spliced base blanks, so that the floor blanks form type structure.

The laminated board is made by laminating the wood according to the forward fiber, staggering the joints, gluing and hot pressing, and then sawing it into a standard-shaped laminated strip, and embedding ribs between two laminated strips to form a joint. For the required floor base blanks, the spliced base blanks are at least composited with wood veneers whose fiber directions are at right angles.

The wood veneer on the base material blank board is compounded with decorative veneer through a conventional composite process, and the wood veneer under the base material blank board is compounded with a wood veneer with a fiber direction at a right angle through a conventional composite process. .

The invention can process a variety of locks, which are beautiful and strong, can meet the tension of the locks, completely change the stress of the floor boards, make full use of various characteristics of wood, make the deformation coefficient of the floor small in use, and meet the needs of various types of locks. It can be used in various environments; due to the finger-joint process, it can fully use various small-diameter timber and other coniferous forests for production, especially saving timber resources and protecting natural forestry resources; it is particularly convenient to install, without glue or keel, saving nearly 100% of the cost. 35%; it has the characteristics of simple structure, simple processing technology, good quality, low cost, convenient installation and good use effect.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings: the present invention is at least made of three layers of plates through a structural composite process, and the intermediate substrate layer is mainly composed of a laminated plate 1 made by a lamination process. As shown in accompanying drawing 1, the described lamination process refers to: lamination of wood veneers according to the forward direction of fibers, staggering and gluing according to the interface and hot pressing to form a laminated board 1 . The finished laminate 1 is sawed into laminate strips 2, as shown in accompanying drawing 2.

As shown in Fig. 3, the present invention splices laminated strips 2 one by one into a base material blank 3, and at least one layer of wood veneers 4 with different fiber directions are compounded on the top and bottom of the base material blank 3 to form Type II. structured. The base material blank 3 shown in FIG. 3 is formed by splicing at least two or more lamination strips 2 with ribs 5 sandwiched between them.

型结构状地板。具体表述是：所述的基材坯料板3上面复合有一层横向的不单板4，即该木单板4的纤维方向与基材坯料板3的纤维方向成直角(90度)；同样基材坯料板3下面也复合有一层横向的木单板4；并形成

型结构状。As shown in Fig. 4, at least one layer of wood veneer 4 with fiber direction at right angles is compounded on the upper and lower sides of the base material blank 3 according to the present invention, forming

Structured floor. The specific expression is: the described base material blank 3 is compounded with a layer of transverse non-veneer 4, that is, the fiber direction of the wood veneer 4 is at right angles (90 degrees) to the fiber direction of the base material blank 3; A layer of horizontal wood veneer 4 is also compounded below the material blank plate 3; and forms

type structure.

Shown in accompanying drawing 5, also be compounded with decorative veneer 6 on the wood veneer 4 above; The fiber directions of the board 4 are at right angles, which increases the deformation resistance of the floor. The description of fiber directions in the present invention being different or at right angles refers to the arrangement of wood fiber directions between adjacent layers.

型结构状。The method for manufacturing solid wood composite flooring according to the present invention is to process the wood into pieces of laminated boards as the floor base material according to the laminated wood process, and then make the laminated boards into laminated slats and splice them together The floor base material blank board is formed, and wood veneers with different fiber directions are compounded on the upper and lower base material blank boards, so that the floor blank blocks form

type structure.

The laminated board is made by laminating the wood according to the forward fiber, staggering the joints, gluing and hot pressing, and then sawing it into a standard-shaped laminated strip, and embedding ribs between two laminated strips to form a joint. For the required floor base blanks, the spliced base blanks are at least composited with wood veneers whose fiber directions are at right angles.

The wood veneer on the base material blank board is compounded with decorative veneer through a conventional composite process, and the wood veneer under the base material blank board is compounded with a wood veneer whose fiber direction is at right angles through a conventional composite process. .

In the present invention, the single wood board is processed into a laminated board through the lamination process and used as the base material of the floor, and then the laminated board strips and ribs that have been made are spliced into the floor base material blank board through the structural compounding process. Wooden veneer is compounded on it. Since the long side direction of this composite floor is along the grain direction of the wood and there are veneer composites on the upper and lower sides, it can process various locks arbitrarily and the processing surface is very delicate. There is no need to open the floor during installation. Glue, play the keel, the cost has been reduced by nearly 35%, and the market prospect is very promising.

The scope of protection claimed by the present invention is not limited to each embodiment described herein, and the specialized technology involved, such as structural composite technology etc., is familiar to the general personnel of this profession, so as long as understand the content and characteristic of the present invention, can do various Various forms of transformation and substitution, and can implement the technology of the present invention conveniently.
