Problems solved by technology

[0003] The object of the present invention is to propose a four-layer solid wood composite floor whose surface boards are horizontally and vertically spliced ​​structures in order to overcome the problems of poor strength and easy cracking when the thin boards spliced ​​horizontally and vertically are used as composite floor surface boards and cork core boards to be glued together. And the technical scheme of its production method; this scheme bonds a layer of thin plates between the core plate and the surface plate, thereby overcoming the phenomenon that the surface plate is easy to crack; at the same time, it solves the problem of short material splicing of the surface plate

Embodiment 1

[0039] Referring to Figures 1 and 2, the surface solid wood board 1, the glued veneer 2, the core board 3 and the back board 4 are bonded to each other to form a solid wood composite floor, and there are tongue and groove 5 and grooves for splicing the floors around the floor. Tongue 6; wherein, the surface solid wood board 1 is composed of short wood blocks glued together horizontally and vertically along the direction of wood fibers 1-2; the short wood blocks are composed of at least two hard wood strips 1-1 spliced ​​and glued together. The short wooden block in Fig. 1 of this embodiment is spliced ​​and glued by seven hard wooden strips, and the short wooden block in Fig. 2 is spliced ​​and glued by thirteen hard wooden strips, and the number of hard wooden strips depends on the width of the hard wooden strips , the width is narrow, the number of hard wood strips required to be spliced ​​to the surface of the floor width is large, and vice versa; and the width of the short ...

Embodiment 2

[0043] Referring to Fig. 3 and embodiment 1,

[0044] Different from embodiment 1, the width of the horizontal and vertical short blocks of spliced ​​surface solid wood board 1 is different; The width of the spliced ​​short wood blocks can make more flexible use of hard wood materials, and at the same time, it can increase the different patterns of the floor surface boards while using short hard wood.

[0045] The hard wood strip in the above-mentioned embodiment 1 and embodiment 2 is hard wood such as oak or walnut or teak or merbau or balsam or jatoba or birch or maple or elm or Southwest birch or hard maple wood. The core board, glued veneer and backboard are soft woods; they are soft woods such as pine or eucalyptus or poplar or meranti.

Embodiment 3

[0047] Referring to Fig. 12 and Example 1, the manufacturing process of the four-layer solid wood composite floor whose surface layer is a horizontal and vertical splicing structure is:

[0048] 12-1. Make surface solid wood slabs with horizontal and vertical splicing structures; process hard wood into short wooden slabs with uniform thickness, splice the short wooden slabs at 90 degrees horizontally and vertically along the wood fiber direction, and then frame Sawn into thin boards, planed on all sides, leveled, trimmed, sorted and balanced, and then used as surface solid wood boards;

[0049]The specific steps are, see Figure 4, hard wood, that is, hard wood such as oak or walnut or teak or merbau or balsam or jatoba or birch or maple or elm or southwest birch or hard maple Short material, sawed and planed into hard wood strips, the dotted line in the figure shows the use of short hard wood of different lengths to saw and planed into hard wood strips; then see Figure 5, the ...

Abstract

The invention relates to a four-layer solid wood composite floor and the manufacture method. The surface plate of four-layer solid wood composite floor is the horizontal and vertical stitching structure and the composite floor comprises a surface solid wood plate, a core plate and a back plate. It is characterized in that a gluing single plate is set between the surface solid wood plate and the core plate and said four-layer plates are bonded with each other; the surface solid wood plate is constituted by short solid blocks gluing in wood fiber direction along horizontal and vertical orders; the thickness of said gluing single plate is less than the one of said core plate. Compared with prior technologies, 1 the invention solves the problem that when the horizontal and vertical stitching thin plate is used as the surface plate to glue with the soft wood core plate, it is bad intensity and easy crack. 2 the invention avoids the floor deformation of wood generated by circumstance temperature and moisture changes so that the floor stability is improved by 6 to 8 times; because it is the gluing single plate under the surface plate, the bonding intensity of end stitching surface plate is strengthened effectively. At the same time the invention makes full use of short hard woods, which can not be used in producing the integral surface plate, and saves the resource of rare tree species.

Description

technical field [0001] The invention relates to a building decoration material, in particular to a four-layer solid wood composite floor whose surface boards are horizontally and vertically spliced ​​and a manufacturing method thereof. Background technique [0002] At present, the multi-layer solid wood composite floor is used in various places, because it has the characteristics of environmental protection, not easy to deform, good viewing effect, long service life, relatively cheap price, etc., so it is widely accepted by people, but the surface layer of solid wood composite floor Most of the hard woods used in boards are rare species with a long growth period. Therefore, it is a problem faced by solid wood flooring producers to fully increase the utilization rate of hard woods; in order to improve the utilization rate of hard woods, for short Hard wood and the side material that is not suitable for the overall surface board are used by splicing. However, due to the thin t...
