CN2895609Y - Bending-resistant solid-wood composite floor - Google Patents

Abstract

The utility model discloses an anti-bend solid-wood composite floorboard, which comprises three or more layers of combined solid-wood strips. The utility model has rabbet and groove on the peripheral sides, a longitudinal groove is arranged on the bottom of the lowest solid-wood strip layer, and the groove is 5-10mm away from the rabbet edge. The groove is 0.2-2mm wide, 0.2-2mm deep. The utility model anti-bend solid-wood composite floorboard has groove on the bottom of the lowest solid-wood strip layer, and the floorboard warp phenomenon caused by bonding can be counteracted, thereby the solid-wood composite floorboard is more easy to process with high yield.

Description

Counter-bending solid wooden compound floor

Technical field

The utility model relates to a kind of decorative ground and uses the floor, particularly a kind of counter-bending solid wooden compound floor.

Background technology

Solid wooden compound floor is a kind of flooring ornament materials of novel high-grade, and the sheet material of its each layer is solid wood.The fiber of each laminate material is crisscross, has both cut down the internal stress of timber, has also changed the feature of the unidirectional same sex of timber, makes the floor become isotropism, thereby dimensional stability is good, little, not yielding, the cracking of expand with wet and contract with dry rate.Solid wooden compound floor has the branch of three layers and multilayer, and each layer bonds together, and in the process of bonding making, the phenomenon that has the ground slab warping takes place, and therefore, very high to making requirement, yield rate is low.

The utility model content

Technical problem to be solved in the utility model provides a kind of counter-bending solid wooden compound floor, and this floor is provided with the bending resistance crank slot at bottommost, under the effect of flexural stress, can delay the flexural deformation on floor.

For addressing the above problem, technical solution adopted in the utility model is: a kind of counter-bending solid wooden compound floor, comprise the plank of solid wood more than three layers or three layers that bonds together, its four limit has tenon and groove, orlop plank of solid wood bottom vertically offers a groove, and described groove is apart from tenon edge 5-10mm.

Wherein, the wide 0.2-2mm of described groove, dark 0.2-2mm.

The beneficial effect that the utility model can reach is: the counter-bending solid wooden compound floor orlop of the utility model plank of solid wood bottom has groove, can offset the floor because the warping phenomenon of bonding generation makes solid wooden compound floor be easier to processing, yield rate height.

The specific embodiment

Fig. 1 is the counter-bending three-layer wood composite flooring structural representation of the utility model embodiment, comprise panel 1, central layer 2 and base plate 3, mutual bonding formation tenon 4 of three and groove 5 are wherein offered a longitudinal fluting 6 in base plate 3 bottoms apart from tenon 5-10mm place, the wide 0.2-2mm of this groove, dark 0.2-2mm.

Claims (2)

1, a kind of counter-bending solid wooden compound floor, comprise the plank of solid wood more than three layers or three layers that bonds together, it is characterized in that: described solid wooden compound floor four limits have tenon and groove, and orlop plank of solid wood bottom vertically offers a groove, and described groove is apart from tenon edge 5-10mm.

2, a kind of counter-bending solid wooden compound floor according to claim 1 is characterized in that: the wide 0.2-2mm of described groove, dark 0.2-2mm.
