Description

Multi-layer solid wood floor

Technical field

The utility model relates to the wood processing technique field, particularly relates to a kind of multi-layer solid wood floor.

Background technology

Along with the raising of people's living standard, wood flooring has become a kind of common used material of people's house fitting-up.At present, alternative floor mainly contains wooden floor and compoiste wood floor.Wherein to form with its characteristics natural, cool in summer and warm in winter attractive in appearance and comfortable sense of touch be people's first-selection to wooden floor.But also there is deficiencies such as need expending a large amount of high-quality timber, not moisture resistance, yielding arch camber even cracking in wooden floor.Nowadays, forest reserves growing tension, the famous and precious timber of high-quality is rare especially, the domestic supply of China is obviously not enough, most of at present dependence on import, but, have to select for use the famous and precious timber of high-quality again for to guarantee that wooden floor has the premium properties that allows the people approve, thereby price is higher, and is progressively up-trend.In fact, existing wooden floor has enough flexural strengths in order to guarantee it, the thickness on floor generally will be more than 16mm, and the ground plate thickness only play stressed effect more than 2/3, have 1/3 thickness just to play wear allowance and decoration function at most, therefore to can be described as waste surprising for existing wooden floor.Moreover the elongation per unit length of wooden floor is big, easily torsional deformation, not moisture resistance characteristics, makes its easy deformation arch camber and have a strong impact on the mood of decoration quality and resident family in actual applications again, and this point is higher and change bigger south performance more so in humidity.Because above-mentioned reason, compoiste wood floor has appearred, it generally comprises wood panel, fiber central layer and wooden base plate, though it has reduced the high-quality wood usage amount, has reduced cost, but intensity is not enough to some extent, and because in order to improve intensity, the fiber central layer is often thicker, thereby causes flexural deformation easilier, cause surface irregularity, comfort is poor.

Summary of the invention

Technical problem to be solved in the utility model is that a kind of high-quality consumption of wood of exploitation is few, cost is low, not yielding and multi-layer solid wood floor that comfort is good.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this kind multi-layer solid wood floor, the panel that it has base plate, middle central layer and is processed by the high-quality solid wood, it is characterized in that all accompanying at least between described base plate and the middle central layer and between panel and the middle central layer the horizontal central layer of one deck, and the texture of described base plate, middle central layer and panel is consistent with the floor length direction, and the texture of described horizontal central layer is vertical with the floor length direction.

Floor with the utility model typical structure is: by the solid wood thin plate of five layers of different-thickness and material and scab by the texture of material in length and breadth direction carry out the combination of science, with the resin dedicated glue glued adhesion of high-strength environment-friendly type, under uniform temperature and pressure, make the floor blank, be processed into floor board block through precision machine tool again and form.Wherein:

The thickness of described panel is 2～4mm, adopts the famous and precious timber of high-quality, is formed by accurate multiple blade saw sawing.

The thickness of described horizontal central layer is 2.5～3.5mm, is formed by general wood board splicing, and plank is advisable to select poplar rotary-cut plate for use.

The thickness of central layer is 7～8mm in described, is formed by general hardwood plate and medium density fibreboard or softwood interval splicing.

The thickness of described base plate is 3～4mm, for the general timber of whole plate or by after the general timber splicing, is formed by accurate multiple blade saw sawing again.

The concrete thickness of each flaggy thickness can be arranged in pairs or groups according to actual needs mutually, and making the floor gross thickness is 12～18mm.

Compared with prior art, the utlity model has following characteristics:

1, the panel of this multi-layer solid wood floor adopts the famous and precious timber of high-quality, processes with accurate multiple blade saw sawing, does not destroy the structure of timber, and the same with wooden floor have a natural timber natural texture true to nature.Performance is better than the rotary-cut veneer.And the thickness of panel reaches 2～4mm, and is thicker relatively, not only increases the longitudinal strength on floor, and make the floor have good woodiness touch, and deadlocked performance also greatly improves, and makes the floor more wear-resisting, and is more sturdy and durable.

2, owing to all accompanying horizontal central layer between central layer between panel and middle central layer, reaching and the base plate, make the symmetry on floor good, mechanical strength is more even, has both strengthened the transverse strength on floor, overcome the horizontal drying shrinkage on floor, the wet distortion of rising and causing again, floor stability is greatly strengthened.In addition, horizontal central layer adopts the poplar material, can play the cushioning effect of counter plate, can improve the defective that produces because of the panel became uneven, improves the gummed of panel and the elasticity on floor.

3, middle central layer is thicker, adopts the splicing at interval of hardwood and medium density fibreboard or softwood, has both improved the wood utilization rate, has reduced the internal stress of timber again, makes the mechanical property on floor more stable.

4, the thick 3～4mm of base plate, with the general timber of whole general timber of plate or splicing, wherein the splicing base plate helps floor stress minimizing, and can utilize narrow timber, thereby improves the wood utilization rate.

5, this multi-layer solid wood floor adopts high-strength environment-friendly type resin glue, bonding strength height not only, and water-tolerant, and also formaldehyde emission is significantly less than the interior decoration standard.

In a word, by reconfiguring of multi-layered sheet, can make the floor both have the natural wood veins and the comfort of natural timber, reduced the intrinsic internal stress of timber again, make the mechanical property on floor more uniform and stable, thereby overcome natural timber, the scope of application on floor is enlarged because of defectives such as the wet easily rising arch of climate change, dry shrinkage and crackings, not only, can also be applicable to heating floor applicable to general occasion.Also have, the used famous and precious timber of high-quality of the utility model multi-layer solid wood floor only is 1/4～1/5 of traditional wooden floor, has improved the utilization rate of high-quality timber greatly, has not only reduced cost, also helps the limited forest reserves of protection; In central layer and base plate adopt general material, its resource is abundanter, comprehensive utilization ratio is higher, so the cost on floor also descends to some extent, and the floor is not easy distortion after mating formation, and favorable economic benefit and social benefit are arranged, and will become the direction that the floor is already developed.
