The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

This specification embodiment provides a fishbone parquet, includes: the fishbone floor is in a parallelogram shape and at least comprises a surface layer, a middle layer and a bottom layer which are equal in size;

the middle layer is a substrate layer, and the substrate layer is formed by splicing more than two substrate unit strips with the same thickness in a tenon-and-mortise mode;

the surface layer is laid on the base material and at least comprises more than two same parallelogram surface plates, and the acute angle degree of the surface plates is the same as that of the fishbone parquet; the parallelogram surface plates are sequentially arranged on the upper surface of the base material layer;

the bottom layer is tightly attached to the lower surface of the middle layer, and the bottom layer is a whole single-plate balance layer.

Referring to fig. 1, the fishbone floor assembly of the present specification is a parallelogram, and the fishbone floor assembly at least includes three layers: the uppermost surface layer, the middle substrate layer and the lowermost bottom layer. Wherein, the uppermost surface layer can be a solid wood layer. The surface layer can be made of precious wood by rotary cutting, slicing or frame sawing, and the like, and can play a role in decoration and the like. The material of the substrate layer can be plywood, is formed by vertically laminating and gluing rotary-cut veneers in the grain direction, has certain elasticity and plasticity, and is used for enhancing the mechanical strength and the dimensional stability of the floor. The bottom layer is a whole veneer balance layer, and the veneer balance layer is a rotary-cut veneer and is used for balancing stress generated by possible deformation of the surface plate and the base material layer.

In the present embodiment, the acute angle of the fishbone parquet of the parallelogram may be 45 degrees, but may also be 30 degrees, 60 degrees, and the like, and is not particularly limited herein. Preferably, the acute angle of the fish-bone parquet of the parallelogram is 45 degrees, that is, the corresponding surface layer, the middle layer and the bottom layer are parallelograms with the same size and an acute angle of 45 degrees.

In this embodiment, the parallelogram-shaped substrate layer is formed by splicing more than two substrate unit strips with the same thickness. Referring to fig. 2, the unit bars of the substrate may be parallelogram-shaped unit bars, or may be triangular, square, or other unit modules. And is not particularly limited herein. Preferably, the base material unit strip is a parallelogram base material unit strip. The fishbone parquet floor of the embodiment of the specification is particularly suitable for floors with large specifications. In this embodiment, four outer edges of the parallelogram formed by splicing the unit bars of the base material are outer edges, and the edges spliced by the internal units are inner edges.

In this embodiment, the skin layer is laid flat on the substrate. The surface plate of the surface layer can be a row or a plurality of rows. Preferably, the skin layer is formed in a row of skins. Referring to fig. 7, in this scenario example, 5 surface plates are attached to one fishbone parquet plate.

Through above-mentioned embodiment, can provide a fishbone parquet floor, especially can provide a big specification fishbone parquet solid wood composite parquet floor, this fishbone parquet floor's dash board press paste extremely on the big specification substrate layer of substrate unit strip concatenation, improve the floor efficiency of mating formation and the quality of mating formation, reduce the requirement to the ground flatness. The large-size base material layer is formed by splicing a plurality of base material unit strips in different directions, and on the premise that the base material structure is unified, the large-size base material layer can disperse and reduce the lateral strain generated in the pressing and pasting process, so that the strain of each direction of the plate edge is uniform, and the acute-angle upward warping of the fishbone spliced floor is avoided. In one embodiment, through a three-layer balance composite structure, the stress of the surface plate and the stress of the bottom layer are mutually offset, and the flatness of the plate surface is improved, so that the quality defects of surface plate sand penetration and the like in the subsequent sanding process are avoided, and the yield is improved. The base material unit strip can also make full use of the remaining narrow materials in the strip opening process, and achieves the purposes of making full use of the remaining raw materials and reducing the product cost.

The fishbone parquet in one example scenario employs a typical substrate layer stitching rule as in fig. 1.

In this scenario, the substrate layer formed by the substrate unit bars is a parallelogram, one side length of the fishbone parquet is the length of the side in the grain direction of the single parallelogram surface plate, and the other side length is the length of the inclined side of the multi-piece parallelogram surface plate after the inclined sides are aligned and tiled. The substrate layer is formed by splicing a plurality of substrate unit strips with the same thickness according to the directions of two adjacent sides of a parallelogram, and can be combined in various ways. The four sides of the large-scale base material are provided with the tongue-and-groove mortises for splicing, and the tongue-and-groove mortises on the same side have the same direction.

In this scenario example, the base material unit strips are parallelogram plywood base materials with the same thickness, and the base material unit strips can be divided into multiple groups according to the length. The side length of the base material unit strip is determined according to the specifications of finished products of the parquet floor with different large specifications and a preset splicing rule. The four sides of the base material unit strip are provided with tongue-and-groove mortises. In this scenario, each of the base material unit bars is a parallelogram, and the obtuse angles and the two side rabbets of each parallelogram have the same direction and are both a tenon or a mortise. Further, in order to reduce the material cost of the product and improve the utilization rate of raw materials, the base material unit strip can be processed by using the base material part which is left after flatly pasting the floor slitting and is not pressed with the surface plate. Furthermore, in order to improve the processing efficiency of the grooves and tongues, the base material unit strips with the same width can be used, the grooves and tongues are unified in the long side direction of the base material strips, and then the base material unit strips are sawed into parallelograms with different lengths. Please refer to fig. 4, which illustrates the substrate layer formed by splicing different substrate unit strips.

In the present scenario example, the substrate unit strips can be spliced into a large-format substrate according to different methods. Wherein the length direction of the unit strips on the four sides is along the four sides of the fishbone parquet floor, so as to ensure the dimensional stability of the large-size base material in different directions. And coating the milky glue at the splicing mortises of the unit strips of the substrate and utilizing mortise-tenon joint combination to ensure that the unit strips are firmly combined to form an integral large-size substrate. The large-scale substrate after the concatenation is fixed thick through the grinder sand light, makes substrate layer surfacing does benefit to follow-up wainscot process. In the pressing and pasting process, the substrate layer is pressed to generate lateral strain. Referring to fig. 8, the lateral strain generated by compression when the substrate layer is a monolithic body is illustrated. As shown in fig. 9, in this scenario, the substrate layer is formed by splicing more than two substrate unit strips, and compared with a monolithic substrate layer, the discontinuous unit strips respectively generate strain, the mortise and tenon structure between the substrate unit strips offsets a part of stress and strain, and the strain on four sides of the large-size substrate formed by splicing is uniformly dispersed, so that acute-angle warping is avoided, and the flatness of the plate surface is improved.

In this scene example, the structure of fishbone parquet is three-layer composite structure, the top layer is many parallelograms table tiling, and the sandwich layer or the intermediate layer or the substrate layer is called, is by more than two the big specification substrate that substrate unit strip concatenation formed, the bottom is whole veneer balancing layer. In order to ensure that the stress of the surface plate and the stress of the bottom plate are uniform when the floor is subjected to dry shrinkage and wet expansion, the thickness of the surface plate on the surface layer is the same as that of the single plate balance layer on the bottom layer. The thickness of the surface plate is consistent with that of the bottom layer, so that the plate surface stress can be mutually offset, and the plate surface flatness is improved.

In one scenario example, when the required skin thickness is greater than the underlying veneer balancing layer, the quality level of the skin should be reduced. And evaluating the quality grade of the surface plate by taking surface defects as indexes, such as knots, thick silk, warping and the like.

In the scene example, the three-layer structure is applied with glue and pressed, so that the stress between the substrate layer and the surface plate and the bottom layer is equal, and the warping deformation of the surface plate is avoided.

In the implementation scenario, the base material unit strips of the plywood are made of elastic plastic materials, lateral strain is generated due to normal stress in the pressing and pasting process, and the strain amount of the unit area is the same. When the substrate layer is the monoblock, because parallelogram different position breadth length is different, the great obtuse angle part dependent variable of breadth length is big, and the less acute angle part dependent variable of breadth length is less, leads to four sides dependent variable inhomogeneous, and acute angle warpage influences the plane roughness. Please refer to fig. 9. The plurality of substrate unit strips are spliced into the whole large-size substrate, so that the lateral strain generated by normal stress in the pressing and pasting process is dispersed and reduced, the strain on four sides of the substrate is uniform, and the warping is avoided.

In one embodiment, the acute angle of the fishbone parquet is 45 °.

In this embodiment, the surface plate is 1 row, the length of the long side of the surface plate is equal to the length of one side of the fishbone parquet, and the surface plate is sequentially arranged to form the surface layer.

In the present embodiment, the preset grade may refer to a quality grade of a watch plate that is conventional on the market. The quality grade of the surface plate is used for representing the surface defect condition of the surface plate. The surface defects of the skin panel may be evaluated on the basis of knots, thick threads, warping, etc.

In the embodiment, the material of the base material unit strip is plywood, and has certain elasticity and plasticity, so that the mechanical strength and the dimensional stability of the floor are enhanced.

In the embodiment, the base material unit strips have the same width, so that the applicability is high, and the calculation and the processing are convenient. In this embodiment, the edge of the substrate unit strip is provided with a tenon or a mortise for splicing with other substrate unit strips.

Please refer to fig. 5 and 6. And the unit strips along any one side of the four edges of the fishbone parquet in the base material unit strips are the base material unit strips in the first base material unit strip group or the second base material unit strip group. In this embodiment, the left and right sides and the upper and lower sides are the upper, lower, left and right directions in normal observation, and the left and right sides and the upper and lower sides can be replaced with each other depending on the placement mode of the fishbone parquet floor. Specifically, for example, when the substrate layer in fig. 5 is rotated clockwise by 90 degrees, the original first substrate unit strip group is the existing second substrate unit strip group, and the original second substrate unit strip group is the existing first substrate unit strip group.

In this embodiment, the first base material unit strips are respectively spliced on the left side and the right side of the base material layer, the second base material unit strips are respectively spliced on the upper side and the lower side of the base material layer, and the four base material unit strips form a parallelogram frame to serve as the outer contour of the fishbone parquet floor. And the third base material unit strips are fully distributed and spliced in the parallelogram frame.

This kind of mode is easy to assemble.

Referring to fig. 5, the length of the long side of the first base material unit strip is equal to the length of one side of the fishbone parquet, and the length of the long side of the second base material unit strip plus the lengths of the short sides of the two first base material unit strips is equal to the length of the other side of the fishbone parquet.

After rotating 90 degrees, the names of the first base material unit strip and the second base material unit strip are exchanged, and the middle drawing of fig. 6 can also be used. The length on the long limit of second substrate unit strip equals the length on one side of fishbone parquet, the length on the long limit of first substrate unit strip adds two the length on the short limit of second substrate unit strip equals the length on the other side of fishbone parquet.

Step 103: sawing the unit bar: the calculated length of the base material unit strip ab is 690mm, in actual production, the fact that the groove and the tongue of one end of the completely assembled base material unit strip and the long-edge groove and the tongue of the base material unit strip c or d are on the same straight line needs to be considered, therefore, the lengths of the base material unit strips a and b are slightly longer than the calculated values by 15-25 mm, and secondary groove and tongue processing of the end part is completed after splicing. The length of the substrate unit bars a and b sawn from the substrate strip is therefore preferably 710 mm. And calculating to obtain the base material unit strips c and d, wherein the lengths of the base material unit strips e and f are 301.3mm and 479.5mm respectively, and sawing the base material plate strips obtained in the step 102 according to the lengths.

Step 104: end processing and tongue and groove: and (4) respectively sawing 45-degree angles at two ends of the sawn unit strip obtained in the step 103, and grooving. Note that the tongue-and-groove directions of the two sides of the obtuse angle of the unit strip are the same.

Step 105: splicing the base material unit strips: and (3) splicing the base material unit strips obtained in the step (104) according to a graph 10, wherein the spliced positions are coated with the milk white glue and are connected through tenon-and-mortise joints. One end of the base material unit strip a and one end of the base material unit strip b are in the same straight line with the tongue-and-groove of the long edge of the unit strip c.

Step 106: trimming: and sawing the other ends of the substrate unit strips a and b to be flush with the grooves and tongues of the long edges d, and grooving.

Step 107: pressing and pasting: and (3) respectively coating adhesives on the parallelogram bottom plate with the thickness of 2mm and the same specification as the finished product and the large-specification base material obtained in the step (106), assembling, and flatly paving the parallelogram surface plate with the thickness of 2mm on the base material to form a three-layer composite structure plate blank. And sent to a cold press where pressure is applied and held for a period of time.
