Description

Bilateral rift grain composite floor board

Technical field

The utility model relates to a kind of decoration wood flooring, especially a kind of bilateral rift grain composite floor board.

Background technology

Traditional wood flooring generally is by poor growth, the harder high-quality log of quality is made the strip monolithic piece of unified specification, a long limit of one side and a side minor face are provided with groove, long limit of opposite side and minor face are provided with the projection that adapts with groove, become the monoblock floor by groove with the projection scarf, though this floor is rich and honour comfortable, elasticity is moderate, but has following defective, and the one, consumable quantity is big, available high-quality timber resources is few, a large amount of fast-growing woods materials are difficult to utilize, and the 2nd, swell-shrink coefficient is big, easily splits and easily sticks up especially temperature, humidity changes slightly with regard to torsional deformation, the 3rd, intensity is relatively poor, and especially groove and projection position are very easily damaged.In order to overcome above-mentioned defective, people develop multi-layer solid wood composite floor, it comprises that panel layer, core layer and backplane level form through gummed, the panel repeatedly flaggies of handling through melamine that adopt more, core layer is that being glued through pollopas by the log section of multilayer criss-cross arrangement is coated with, is hot pressed into a whole plate, and base plate is through the moistureproof ply of paper of the impregnated balance of melmac.Though the intensity and the durability of wood flooring can be improved in the floor of this structure, but because central layer is an overall structure, still easily buckling deformation, especially more yielding distortion in the room of underground heat is installed, its elasticity deficiency in addition, comfort is short of to some extent when trampling, simultaneously, the central layer on this floor is combined through crisscross by the log section, and timber is had relatively high expectations, and can not make full use of fast-growing woods and small dimension wood.

The utility model content

The purpose of this utility model is to overcome the prior art deficiency, provides a kind of and can make full use of the fast-growing woods material, reduces high-quality forest consumption, is beneficial to environmental protection and ecological protection, not variable torsional deformation, robust rift grain composite floor board.The purpose of this utility model realizes by following technical proposals: the utility model is by panel layer, core layer and moisture retardant balance layer gummed form, core layer two long limits are weedtree rotary-cut monolithic, by direction gluing in the same wooden line, assembly, hot pressing, the multilayer rift grain composite plate rectangular strip that sawing forms, two composite plate rectangular strips are spliced into substrate with uniform thickness fast-growing woods material rectangular block therebetween, glue together respectively on the substrate two sides 1-2 layer composite plate, form central layer, a long limit of central layer one side and a side minor face are provided with groove, and long limit of opposite side and minor face are provided with the projection that adapts with groove.

Compared with prior art, the utility model can make full use of growth rapidly, biomass is big, become a useful person early, the fast-growing woods material that 3-5 can fell, as long as fast-growing woods once grows into forest the scientific management operation, felling rationally can forever utilize.It is few to significantly reduce resource; the speed of growth is the high-quality consumption of wood slowly; help ecological environmental protection; because the utility model core layer is by the rift grain composite plate and has humidity resistance; the regular splicing of polylith small-sized rectangle wooden unit (bar) (finger or non-finger); always have certain interval and little groove between splicing block; fundamentally overcome the distortion of wooden floor and compoiste wood floor; warpage issues; even it is installed in the underground heat room, also can keep its breathing balance, the utlity model has wooden floor and composite floor board advantage separately; both sturdy and durable; rich and honour again comfortable, groove and projection on the long limit of its central layer are opened on the rift grain composite plate, have both increased intensity; make it smooth smooth again, be convenient to install.In sum, the purpose of this utility model can realize.

Description of drawings

Fig. 1 is the utility model configuration diagram.

The specific embodiment

As shown in Figure 1, the utility model is by panel layer 1, core layer and moisture retardant balance layer 5 add hot gluing and form, said panel is through the impregnated famous and precious timber section of melmac, the wear-resisting ply of paper of heat seal one deck thereon in case of necessity, or the surface is coated with wear-resisting UV resin or the PU resin increases its abrasion resistance, said base plate is through the moistureproof ply of paper of the impregnated balance of melmac, core layer two long limits are weedtree rotary-cut monolithic, and by direction gluing in the same wooden line, assembly, hot pressing, the rift grain composite plate rectangular strip 2 that sawing forms, direction is identical with the rectangular strip length direction in this rectangle striped.Its length is preferably consistent with the composite floor board block length.Said gluing or glue together used glue and be modified urea-formaldehyde resin glue, its water resistance, high temperature resistant, degree of adhesion reach the JASNO955-1991 standard, and meet Japanese JIS and peel off experimental standard.Burst size of methanal reaches the E1 international standard.Two rift grain composite plate rectangular strips are spliced into substrate with uniform thickness fast-growing woods material rectangular block 3 therebetween, said splicing can be a finger, it also can be non-finger, generally with regular be arranged as good, glue together respectively on the substrate two sides 1-2 layer composite plate, form central layer, a long limit of central layer one side and a side minor face are provided with groove 4, and long limit of opposite side and minor face are provided with the projection 6 that adapts with groove.

Claims (1)

1, a kind of bilateral rift grain composite floor board, by panel layer (1), core layer and moisture retardant balance layer (5) gummed form, it is characterized in that: core layer two long limits are weedtree rotary-cut monolithic, by direction gluing in the same wooden line, assembly, hot pressing, the multilayer rift grain composite plate rectangular strip (2) that sawing forms, two composite plate rectangular strips are spliced into substrate with uniform thickness fast-growing woods material rectangular block (3) therebetween, glue together respectively on the substrate two sides 1-2 layer composite plate, form central layer, a long limit of central layer one side and a side minor face are provided with groove (4), and long limit of opposite side and minor face are provided with the projection (6) that adapts with groove.
