Abstract

The utility model relates to a nondeforming wood sandwiched floor which comprises a surface layer board, a core board and a bottom layer board, wherein the surface layer board is made of splicing solid wood, the core board between the surface layer board and the bottom layer board is made of flat splicing wood strip blocks, and the wood stripes of the surface layer board of the surface layer and the wood stripes of the core board are crossed. Both sides of each floor strip are provided with the concave-convex dovetail orbit type engaging structure. The humidity of each layer material of the utility model is homogeneous. Because the wood stripes of the surface layer board of the surface layer and the wood stripes of the core board are crossed, the ability of resisting the deformation and layering of the core layer is enhanced, and the deformation caused by the longitudinal and transversal stress of the material fiber and the arching of floor can be reduced. The dovetail orbits concavely and convexly engaged at both sides enlarge the contact area of the slicing sides and improve the binding force and natural tightening force between floors, and consequently, the defect of the deformation of the floor strips can be eliminated and the width of a vertical seam of the spliced floor strips is reduced.

Description

On-deformable folder wooden floor

Technical field

The utility model relates to a kind of interior decoration ground plank.

Background technology

There are pure wooden floor, composite fibre wood skin composite floor board and consolidated floor three big series of products in the floor that is used for interior decoration in the known technology.Pure solid wood, composite fibre wood skin wood flooring easy deformation and make ground relief, waste material.Pure solid wood plate is subject to the variation of weather drop, is out of shape under the effect of the temperature difference and interior external carbuncle.It is uneven that ground is occurred.Composite fibre wood skin composite floor board and consolidated floor top layer are adopted paster or are pasted wooden skin, and top layer and the moisture rate variance of interior interlayer material are big, are subject to weather, environment, humidity, temperature effect, produce distortion and layering, unstable properties.For keeping away consequent distortion, the seam of broad is all left on these floors between the batten when splicing.The connection seam that their adopt is concavo-convex vertical masonry joint, is vertical side edge to edge fit, and the identical contact surface between floor strip is little, and less stable is easy to generate the seam dislocation and the imbalance of direction stress in length and breadth, the distortion that causes.

Summary of the invention

It is little that the purpose of this utility model provides a kind of floor strip butt-welded side seam, dock reliable and stable, on-deformable folder wooden floor.

The purpose of this utility model is to realize like this.A kind of on-deformable folder wooden floor, comprise musculus cutaneus plate, central layer and bottom plate, it is characterized in that: the musculus cutaneus plate is the jigsaw solid wood, central layer between musculus cutaneus plate and the solid wood bottom plate such as is at flat splice plate stick, and the central layer batten line of the musculus cutaneus plate batten line of surface course and its lower floor intersects, and the floor strip dual-side has concave, convex swallowtail track formula engaging structure.

The utility model has following beneficial effect than prior art.

Because each layer all adopted wooden solid wood, the full solid wood multi-layer combining structure of employing, material moisture content equalization.The splice plate stick of surface course musculus cutaneus plate batten line and the cross arrangement of central layer batten line, batten piece are taken the wood particle bar that stays behind the big specification materials with whole timber and are combined into, and can save timber greatly, reduce the waste of timber resources.And can strengthen sandwich layer resistance to deformation and the opposing layering ability, significantly reduce material fiber in length and breadth to the distortion of stress effect and the arch camber on floor.Be by the rail mounted combination of linking closely between the every wood flooring, improved existing wood flooring and be with directly being attached on the floor and produce yielding have crack and not firm element.But the swallowtail track formula engaging structure that floor strip dual-side concave, convex engages, strengthened the contact area of side butt joint and improved the adhesion between floor strip and fited power naturally, thereby eliminated the defective of floor strip easy deformation, reduced the vertical masonry joint width of floor strip butt joint.Striped is natural, attractive in appearance, and reliable and stable.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.

Fig. 1 is the structural representation of first embodiment of the present utility model.

Fig. 2 is the structural representation of second embodiment of the present utility model.

In Fig. 1, musculus cutaneus plate 1 is bar shaped jigsaw solid wood, and the central layer 2 between musculus cutaneus plate 1 and the bottom plate 3 such as is at flat splicing solid wood stick 4.Bottom plate 3 is wooden skins.Surface course is become by polylith solid wood plane jigsaw face, color striped nature, and drying is to humidity 5-8 degree, and middle central layer 2 is pressed musculus cutaneus plate 1 batten line and is intersected with batten piece batten line in fact, and drying is to humidity 5-8 degree.Batten piece 4 is taken timber clout wood particle bar and is combined into.Can save and save timber greatly like this.Bottom be wooden skin drying is to humidity 5-8 degree, bottom plate 3 wooden micromicros are built into one with whole timber rotation and are wholely magnified wooden skin by the outstanding machinery of building of large-scale rolling, again by the size of wood flooring morsel again.Like this, can expand the scope of application, raise the efficiency, can avoid wood flooring to cause the waste of splicing because of the wood size restriction again.In Fig. 1 embodiment, the swallowtail track formula mesh form that the floor strip dual-side can engage with concave, convex can be the swallowtail track formula mesh form that is shaped on the male and female structure on the slotting face of inwall one side of wood flooring side slot and cutting.In the embodiment shown in Figure 2., described concave, convex swallowtail track can be the curved surface swallowtail track, it can be the dovetail groove that has circular shape.Can strengthen the contact area of side butt joint like this, improve the adhesion of docking between floor strip and fit power naturally, can eliminate the distortion of floor strip again, reduce to dock the vertical masonry joint width.Improve existing wood flooring and directly be attached to the factor that easily produces distortion on the floor.

Only manage the above-mentioned specific embodiments more of the present utility model of having listed; to one skilled in the art; modification or the correction that can under the situation that does not exceed claim institute restricted portion, make to the utility model; make shaped form etc. into such as the swallowtail track that concave, convex is engaged, also should be at the row of protection of the present utility model.

The utility model also can be used for ceiling, wallboard and screen etc.

Claims
