Abstract
A buffer enhanced four-layer engineered wood floor comprises a surface layer (1), a core layer (3) and a bottom layer (4). A buffering layer (2) is arranged between the surface layer (1) and the core layer (3); wood grains of the surface layer (1), the buffering layer (2) and the bottom layer (4) are all consistent and longitudinally arranged, and wood grains of the core layer (3) which is formed by rectangular strip-shaped plates (5) arranged in parallel at intervals are horizontally distributed. The engineered wood floor is special for being adopted as a floor or a wall board for decoration of a room, and by being additionally provided with the buffering layer, compared with universal three-layer engineered wood floors, the engineered wood floor not only solves the phenomena that the original three-layer engineered wood floor is easy to have wave-shaped strips and the surface wood is easy to crack, leads the surface of the core layer to form a continuous gluing interface, and enlarges the glued area of the surface layer so as to improve the gluing strength, but also plays a traction role on deformation of the surface woods, thereby further improving the stability of the floor.
Description
Technical field
The utility model relates to a kind of laminates, specifically is that a kind of four layers of plank or batten laminate the solid wooden compound floor that gummed forms.
Background technology
Get consumer reception thereby general three-layer wood composite flooring; By the solid wood dash board of hard, in the sandwich layer and the veneer bottom of soft solid wood bar; Form through applying glue hot pressing, this three-layer wood composite flooring has the wooden floor confers similar advantages, and is attractive in appearance etc. like surface abrasion resistance, wood grain.Because of when making, having rejected natural defects such as knot, channel, cleaner attractive in appearance, and cost is low, can rationally utilize the high-quality precious timber, and therefore well received, extensively adopt.As if but this floor is asymmetric because of inconsistent, the structure of three-layer-material, also is difficult to exist problem unstable, distortion with avoiding, to this, becomes insider's focus.CN101173556 disclose Liao Hongcheng's " solid wooden compound floor ", be the billet plate sandwich layer that original interval is horizontal, use the central layer that tongue-and-groove is combined into monoblock instead, to gain in strength and resistance to deformation.CN1197876 disclose Che Ping Lei's " prevent three-layered glued wood floor distortion method ", be on the monoblock base plate, to adopt the icking tool crack, stay round or press the method for oblique trace to overcome the distortion on floor.Also there is article to introduce base plate and adopts distortional stress little conifer; The conditioned time that advocate to increase each layer blank is arranged; Following three layers change symmetrical structure into by mutually perpendicular dissymmetrical structure in having in the suggestion, make balancing of stresses or the like, but do not retrieve the technical scheme that increases cushion coat.
The utility model content
The technical problem that the utility model will solve provides a kind of four-layer real-wood composite floor that cushions enhancement mode.
The technical scheme that solves the problems of the technologies described above employing is: this buffering enhancement mode four-layer real-wood composite floor, form by surface layer, sandwich layer and bottom, and it is characterized in that between surface layer and sandwich layer, cushion coat being arranged; The all consistent vertically arrangement of the wood grain of surface layer, cushion coat and three layers of bottoms, the wood grain cross direction profiles of the sandwich layer that is arranged in by rectangle batten spaced and parallel.
Said surface layer plate is by the thick 2-4mm of the little thin plate of monolithic, wide 120-210mm, long 180-500mm, air-dry density>=0.7g/cm
3The little thin plate of polylith high-quality be tiled in the superiors.
Said cushion coat is that thick 0.8-1mm, long 2.4-2.5m, air-dry density are 0.3-0.5g/cm
3Veneer, be laid on the second layer.
Said sandwich layer is 0.27-0.4g/cm by the wide 30-50mm of monolithic batten, thick 7-9mm air-dry density
3Polylith rectangle batten one by one spaced and parallel arrange and to form, spacing 3-5mm is layered on the 3rd layer.
Said bottom is thick 1.7-2.5mm, long 2.4-2.5m, air-dry density 0.3-0.5g/cm
3Veneer, be laid on the 4th layer.
The beneficial effect of the utility model is: increased cushion coat; Both improve original three-layer real-wood composite plate and be prone to form wavy striped and top layer timber crack phenomenon; Make core layer surface form the progressive gluing interface again; Increase the surface layer adhesive junction area, improve bonding strength, and the distortion of top layer timber is worked the effect of holding up.Improve floor stability.
Description of drawings
Fig. 1 is the decomposition attitude layer structure sketch map that the little thin plate dislocation of surface layer is arranged.
The decomposition attitude layer structure sketch map that Fig. 2 is arranged side by side for the little thin plate of surface layer.
The specific embodiment
The utility model details below in conjunction with embodiment: from residing geographical environment of the applicant and distribution of material situation; Consider the desired performance indications in floor, the timber composite factors such as situation and cost of material that are easy to get; The most preferred embodiment that provides is: surface layer 1 is used the polylith oak; Thick little thin plate 6 for 3mm, wide 150mm, long 1200mm by monolithic is arranged in the superiors, almost covers the monoblock veneer of cushion coat 2, the little thin plate 6 dislocation splicings as shown in Figure 1 of each piece; Cushion coat 2 use length and width and surface layer coupling, long as 2.5m, widely be 1.3m, thick board using poplar board as 0.8mm; Sandwich layer 3 usefulness rectangle China fir battens 5, every wide 40mm, thick 8mm, long 1.3m, horizontal parallel arranging at interval one by one, two adjacent strip spacing 4m arrange shared entire area and surface layer and cushion coat and are complementary; Bottom is with length and width and area and three layers of coupling of its top, the board using poplar board of thick 2mm.The width of this composite floor board surface layer, cushion coat and bottom, the length of each batten 5 of sandwich layer are pressed the platen width of customer requirements, press and are decided.Or be that 2.54m, the wide 1.3m of being make bottom and cushion coat with commercially available veneer length, the width of arranging of the length of all the other battens, the little thin plate of surface layer all is complementary with the size of veneer.When joining base, the board using poplar board of the little thin plate of surface layer 1 every block of oak 6, cushion coat 2 and three layers of grain of wood of board using poplar board of bottom 4 are consistent vertically arranges, the texture of the square China fir batten 5 of every block length of sandwich layer 3 is transversely arranged.During applying glue,, to the board using poplar board double spread of cushion coat, select urea-formaldehyde glue for use again, single spreading amount 140g/m to the upper surface gluing of the board using poplar board of bottom
2, the solid content 48% of glue presses down 6min at 110 ℃, 1Mpa pressure, removes pressure then, unloads plate, smooth stacking.
The little thin plate 6 of surface layer also can vertically be arranged side by side, and is as shown in Figure 2.The spacing of adjacent little thin plate should be slightly larger than the width of saw kerf, in a word, with floor in a narrow margin, should be arranged side by side, and with the wide cut floor, the arrangement that should misplace needn't be sawed again and is divided into floor in a narrow margin.
The technological parameter of all the other embodiment; Can be in the application's material elect in the scope of listed each item relevant parameter interval value, by above-mentioned most preferred embodiment same procedure, all can process this composite floor board again; This is that industry those of ordinary skill is grasped, and does not pardon and launches one by one.
