In recent years, domestic three-layer wood composite flooring export market was very good.Because European countries' cost of production is excessive; Mainly be that technical costs and investment of production equipment are excessive, add the powerful stimulation and the domestic aboundresources of Euro, raw material and cost of labor are low; Technology, technology have reached European standard again, so European travelling trader purchases to China.

Now, although market, floor product is numerous, kind is varied, because of structure, mechanism difference, causes its problem that in application, reflects also to be had nothing in common with each other between different product; Really, can also solve through the control quality because the very different floor that causes of quality in use produces such-and-such problem.But some will be because the structure or the material problem of product itself will adopt other the technological means with novelty to solve.

Just as the present three-layer solid wood floor on the domestic and international market because the humiture of various places is inconsistent even differ very big when mounted, causes the floor to upwarp or curved down easily, even because the serious problems that the excessive generation of stress is come unstuck or come unglued.

Summary of the invention

The utility model has overcome the shortcoming of technology in the past, and purpose is a kind of three layer process wooden floors of providing the user performance more superior.

The goal of the invention of the utility model realizes through following technical scheme: a kind of three layer process wooden floors are overlayed by surface layer, intermediate layer central layer and bottom and japanning or oil forms; Surface layer is parallel and symmetrical up and down with bottom, is made up of the only sheet of solid wood or many jigsaw; The intermediate layer central layer wants triangle central layer base material to form by a plurality of right angles that have tongue and groove etc., and the shrinkage joint is left in central layer base material junction, and intermediate layer central layer upper and lower surfaces all has the ventilation noise reduction groove of symmetry.

Described a kind of three layer process wooden floors; The central layer base material is provided with tenon on a right-angle side; Another right-angle side is provided with female groove; Adopt the tongue and groove mode of this tenon groove structure to connect between the central layer base material and adopt environment friendly aldehyde-free glue high pressure gluing firmly simultaneously, the central layer base material connects the intermediate layer central layer of back rectangularity.

Described a kind of three layer process wooden floors, the batten direction of intermediate layer central layer is vertical with the grain direction of surface layer and bottom; The grain direction out of plumb of the shrinkage joint of intermediate layer central layer and surface layer and bottom.

Described a kind of three layer process wooden floors, the central layer base material of right angled isosceles triangle shape adopts the batten of solid wood leftover pieces to form so that environmental protection glue is gluing.

Described a kind of three layer process wooden floors, surface layer is consistent with underlayer thickness, and the thickness of intermediate layer central layer is surface layer and underlayer thickness sum.

After adopting aforesaid technical scheme, the utlity model has following superiority:

The utility model is because bottom, intermediate layer and surface layer symmetry and orthogonal, guaranteed the three-layer solid wood floor contraction of not expanding.Though this Artistic floor is simple in structure, segmentation on the structure, and leave the shrinkage joint, Golden Triangle, on have the ventilation noise reduction groove of equilibrium water conten, it is balanced and can not produce internal stress at three layers of floor water content of different weather to have guaranteed that the back is installed on the floor.The shrinkage joint of central layer is not on the vertical direction of surface layer and bottom wood grain; So both changed the characteristic of the unidirectional same sex of timber; Make the floor become isotropism; Also make every ground intralamellar part can freely stretch and outside smooth constant, the existing intensity in floor can allow its internal freedom to stretch and two-layer up and down maintenance balance, smooth again when humiture changes like this.Therefore, the floor in addition be applied in underground heat or the island wet environment under can the expansion bending arch camber yet.The feature of environmental protection and the intensity of ground slab integral meet or exceed wooden floor, and stability is compound or three-layer wood composite flooring considerably beyond traditional solid wood.Therefore, thoroughly solved traditional wooden floor because of moisture expansion and drying shrinkage craze and transfiguration and three layers of tradition or multi-layer solid wood composite floor upwarp because of the wet weather degree changes, following curved problem.
