The specific embodiment
Below in conjunction with accompanying drawing, this practical solid wood foor is described in further detail.
As shown in FIG. 1 to 3, this practical solid wood foor consists of solid wood board 1 and PVC plate 2, between PVC plate 2 and solid wood board 1, be fixedly connected with, the back side at solid wood board 1 is shaped to the cellar area piece by even isolated groove 11, described solid wood board 1 moisture content 5%～8% and thickness after temperature is 40～60 ℃ of lower vacuum drying are 8～20mm, wherein preferred value is 7～15mm, the thickness of PVC plate 2 is 2～5mm, the degree of depth of each groove 11 be solid wood board 1 thickness 1/5～1/2, wherein preferred value is 1/3～1/4.Wherein the present invention adopts vacuum drying technique, makes described solid wood board moisture content accurate, can reach 5%～7%, optimum value is 6%, depending on different wood, plants, and part hardwood moisture content must be below 5%, even can make timber reach the state of over dry, floor balance, stable, quality is more secure.
The back side of solid wood board 1 is by the groove moulding box-shaped cellar area piece of length direction and width, and the distance between equidirectional and adjacent described groove is 10～300MM, and recess width is 1～5MM.Wherein the interval at the groove of length direction is 10～80MM, and the interval of width is 30～300MM.Solid wood board 1 of the present invention refers to original plank, not by the bonding solid wood composite board formed of plank in layer, by the bonding solid wood composite board formed of the plank more than two, it not indication solid wood board of the present invention, indication solid wood board of the present invention is the direct plank piece of excision forming from the trees cylinder, middle without any plank and plank between bonding.Bottom surface at PVC plate 2 is shaped to honeycomb structure.Wherein the cellar area piece can be also circle and/or the long-pending piece of annular.
Between PVC plate 2 and solid wood board 1, by no-solvent type polyurethane adhesive and curing compound, be fixedly connected with, at solid wood board 1, one of relative two ends end is provided with splicing tenon 12, and the other end is provided with the splicing groove 13 in mating connection with splicing tenon 12.
Spacing distance, groove size, the thickness of solid wood board 1 and each parameter of thickness of PVC plate 2 of being below groove 11 of the present invention are coordinated the embodiment arranged in pairs or groups mutually:
Embodiment 1: solid wood board 1 thickness 10mm, PVC plate thickness 2mm, depth of groove 3.0～3.5MM, the recess width 2MM of each groove.
Embodiment 2: solid wood board thickness 12mm, PVC plate thickness 2mm, the depth of groove 6MM of each groove, recess width 3MM.

Embodiment 4: solid wood board thickness 15mm, PVC plate thickness 3.5 or 5mm, the depth of groove 7MM of each groove, recess width 4MM.
On the long limit of solid wood board 1 and/or the side of the PVC plate 2 at minor face two ends be provided with identical oblique section, be in two relative sides, or four sides are equipped with oblique section.Oblique section consists of skew surface part 212 and straight planar section 211, skew surface part 212 is formed by connecting by two or more cambered surfaces are smooth, straight planar section 211 is located at an end and/or the two ends of skew surface part, the outline-shaped that is serpentine, between skew surface part 212 on oblique section during two solid wood foor splicings between two PVC plates, contact connects, seam becomes tight state, can prevent that like this sealing, moisture enter the gap cavity in solid wood board, therefore reached the purpose of waterproof and dampproof gas.Be provided with gap 21 between the straight planar section in panel side between two PVC plates, gap width is 0.2～0.3MM, is provided with gap 22 between the end face of two solid wood board bottom surface sides, the gap that gap width is 0.4～0.6MM, these gap 22 preferred valueses 0.40, or 0.45, or 0.5 or 0.8.The end face of two solid wood board bottom surface sides refers to the end face that is connected side with the PVC plate, and with the end face of the aligned inside of the oblique section of PVC plate bottom side.The splicing tenon of two solid wood boards projection end face with at the bottom of corresponding splicing groove between also be provided with gap 23.Due to the space of expanding with heat and contract with cold of having reserved the monolithic solid wood board, so can effectively prevent floor deformation and the warpage that whole splicing is good, strengthened again the performance attractive in appearance on the floor of having spliced simultaneously.
Wooden floor of the present invention has following advantage:
1) due to solid wood board of the present invention moisture content 5%～8% after temperature is 40～60 ℃ of lower vacuum drying, make like this solid wood board in or close to the over dry state, the dry and cracked minimizing of solid wood board, the stress of solid wood board is little, thereby has reduced deformation extent.
2) thickness of solid wood board is 8～20mm, and PVC plate thickness 2～5mm is thinner than the common floor consisted of a solid wood board like this, but the performance requirement that meets the wooden floor of national Specification, if solid wood board is too thick in the present invention, the PVC plate is too thin, easily deformable, sound-absorbing effect, moistureproof and waterproof deleterious, particularly the PVC plate is too thin, and during the out-of-flatness of ground, the PVC plate can not play buffering effect, cause the trouble while mating formation, the planarization that affects the Integral floor face is attractive in appearance; If solid wood board is too thin, the PVC plate is too thick, and the modulus of elasticity of solid wood part does not reach standard-required, affects impact resistance and floor intensity.The performance requirement of the wooden floor do not meet national Specification aspect the intensity on shock resistance and floor in.
3) because the back side at solid wood board is shaped to the cellar area piece by even isolated groove, and described solid wood board moisture content 5%～8% and thickness after temperature is 40～60 ℃ of lower vacuum drying are 7～15mm, PVC plate thickness 2～5mm, the degree of depth of each groove is 1/5～1/2～1/3～1/4 of solid wood board thickness, solid wood stress and anti-warpage and distortion have so greatly been eliminated, can control to solid wood stress and buckling deformation to minimum, it because expand with heat and contract with cold, is the normal variation of a lot of materials of nature, and timber more a characteristic, that is exactly moisture expansion and drying shrinkage, with respect to timber, moisture expansion and drying shrinkage is much bigger on more responsive than the degree of heat expansion shrinkage to amplitude, to affect the biggest factor that timber size changes, solid wood board can change in three directions when bulking and drying shrinkage, can be at width, length direction, and thickness direction changes.And in these three variations, because length direction is comprised of long fibre, change in length is very little, and aspect thickness, because plank is relatively thin, the changing value reflected is less also, for example rate of change is 3%, the plate of thick 20mm, and varied in thickness is only also 0.6mm, and as floor, the variation of thickness direction is can not produce the phenomenon of extruding, and the space of distortion is arranged.And the distortion of width has larger impact, and, because the productive life of timber differs, timber can be very not straight because of when growth, the density at each position is inconsistent, will produce the distortion of plate all directions inconsistent, and the amplitude that produces moisture expansion and drying shrinkage differs and cause distortion and the distortion of plate face.If but opened crisscross back-trough of the present invention on backboard, the change of essence will occur in situation.Common solid wood board (situation during bulking): if wide by 2% coefficient expansion, be the plate of 150mm, change width can, at 3mm, can become 153mm, as be applied on floor, parting between two plates is less than 3mm, and ground will be swelled, is out of shape, and even squeezes bad floor.And solid wood foor of the present invention, after by groove, it being divided into to the grid of a plurality of deciles at back due to solid wood board, on the one hand, each side has groove can drive power to external carbuncle, on the other hand, between each power, cancel out each other, can reach equilibrium state, even distortion, also very small, the wide plate of 150mm for example, after being divided into 6 lattice, every lattice are 25mm, be deformed into 2%, its amplitude of deformation is 0.5mm, and other direction has groove, the width deformation of actual full wafer plate is only also 0.5mm, distortion with respect to aforementioned common solid wood board 3mm, reduced undoubtedly the distortion more than 80%, after back-trough has been drawn at the back side simultaneously, be actually the thickness that has indirectly reduced plate, because the stress of the thicker inside of plank is just larger, after the plank attenuation, the corresponding minimizing of its internal stress, and because back cellar area piece is cancelled out each other as the stress between blockage, can make the plank internal stress reach relative equilibrium, therefore, under square one, equal temperature and humidity change, solid wood board of the present invention is out of shape less than common solid wood board on deformation direction, it is wet poor more to adapt to, the temperature difference.And the floor formed by the plywood pressing for solid wooden compound floor, its distortion is same the same with common solid wood board, even if at composite floor board, groove also is set, still can't solve this buckling deformation problem, because all there is solid wood stress in each layer of plank, therefore this layer of groove can't change the solid wood stress of other layer of plank, when a generation bulking and drying shrinkage, and the generation of distortion nature, solid wooden floor and the aforementioned common solid wood board for monolithic, know that by front surface analysis it is once bulking and drying shrinkage occur, be out of shape even more serious, for this reason, also must cut down stress by fluting, but in order to meet national standard, must meet shock resistance and requirement of strength, must increase thickness, certainly will cause waste like this, increase cost, and ground is not at ordinary times, solid wood board contacts with the ground dryness, cause the trouble of mating formation, and directly enter solid wood board when ground is wetly, floor after mating formation is out of shape by the generation bulking that affects of moisture, and when ground is dry, occur dry-shrinkage deformed, bulking distortion and dry-shrinkage deformed alternately occurring, directly affect the application life of wooden floor.And adopt structure of the present invention and sized data, the degree of depth value of groove (directly affecting the size of solid wood stress and buckling deformation and the Thickness of solid wood board) particularly, adopting the degree of depth of each groove of the present invention's regulation is 1/5～1/2 of solid wood board thickness, be equivalent to subdue the stress of solid wood board 2/3～1/2 thickness part, under the performance effect that the solid wood stress of remainder has at PVC plate (bonding force) and the over dry state of solid wood board own, obtain overcoming and control, therefore floor of the present invention had both guaranteed that floor had advantages of the wooden floor that monolithic is solid, aspect thickness, also greatly reduce, saved a large amount of timber, reduced cost, wherein the solid wood board back side is by the scheme of the groove moulding box-shaped cellar area piece of length direction and width, both processed simple, subdued again solid wood stress, warpage and distortion have effectively been prevented.And when the cellar area piece long-pending piece that is circle and/or annular or prismatic, more be tending towards balanced except having subdued solid wood stress, also overcome box-shaped cellar area piece and produced new stress at place, corner position simultaneously, and the degree of depth of groove can reduce, make the thickness of monoblock plank also reduce, timber is further saved, and further reduces, in the situation that same thickness, its anti-warpage and anti-deformation are more effective.As can be seen here, the present invention coordinates collocation mutually by spacing distance, groove size, solid wood board thickness and each parameter of PVC plate thickness of groove, and a fine difficult problem that solves the wooden floor buckling deformation makes the distortion warpage of monolithic wooden floor to minimum.
The control of the buckling deformation that 4) wherein between PVC plate and solid wood board, bonding firm degree direct influence PVC plate causes the solid wood stress of remainder, particularly ground is often wetly, bonding insecure, just lost the function of PVC plate, and by no-solvent type polyurethane adhesive and curing compound, be fixedly connected with between PVC plate of the present invention and solid wood board, efficiently solve this problem, no-solvent type polyurethane adhesive and curing compound can desiccated woods, again can bonding PVC plate and solid wood board.But regulation can not be for plastics such as PE, PP in the manual of no-solvent type polyurethane adhesive, and people therefore can be by PE, PP fixed pattern thinking PVC is also got rid of, and adopt other viscose glues, but these viscose glues are all insecure, particularly meet the ground moisture, lose soon viscosity, therefore the scope of application of power of the present invention row manual regulation has well solved strong bond problem between PVC plate and solid wood board.
5) PVC plate bottom surface is shaped to honeycomb structure, and when ground is uneven, the honeycomb structure of PVC plate and elastic performance thereof, facilitated mating formation of this uneven ground.Honeycomb structure simultaneously also can with floor or glue-line forming section cavity, and play the effect the same with the hollow sound control glass, play the effect of vibration damping and sound-absorbing, the PVC plate is except the sound absorption as the vibration damping layer, its honeycomb structure is the sucker of badge fish also, make floor and ground that more frictional force and absorption affinity be arranged, thereby increased its skid resistance, reduce the displacement on floor.
6) contact connection between the skew surface part on the oblique section between two PVC plates when two solid wood foor splicings in the present invention, be provided with the gap of 0.2～0.3MM between the straight planar section of panel side between two PVC plates, be provided with the gap of 0.4～0.6MM between the end face top layer of two solid wood board bottom surface sides, solved the distortion warpage issues of whole wood flooring, because under different environment temperatures and humidity, the stress of monolithic wooden floor and buckling deformation coefficient difference, therefore also needing to solve this globality is the distortion warpage issues between each piece solid wood foor, if the gap between the end face of the gap be provided with between the straight planar section of panel side between two PVC plates and two solid wood boards is too large, stress and the buckling deformation of monolithic wooden floor have been encouraged, if too little, spalling likely occurs, affect the application life of whole wood flooring.Yet in existing wooden floor or compoiste wood floor, in order to guarantee each floor splicing seams gap minimum (or seamless link) on panel, must between each bottom surface, floor, leave gap, when ground is wetly, moisture causes bulking from gap with entering and affects application life on floor, and the present invention, between skew surface part on oblique section during due to two solid wood foor splicings between two PVC plates, contact connects, the bottom surface that is equivalent to each solid wood board forms a sealed compartment, even if ground is wetly like this, also can't enter the solid wood flaggy by the PVC plate, thereby eliminated the solid wood bulking distortion caused because ground is wetly fully.Wherein between the straight planar section in panel side between two PVC plates, be provided with the gap of 0.2～0.3MM, reserved the spatial accommodation of molecule, reduce the impact of molecule on the planarization between floor; Be provided with the gap of 0.4～0.6MM between the end face of two solid wood board bottom surface sides, reserved the moisture expansion and drying shrinkage deformation space between two solid wood boards.
In a word, the present invention is simple in structure, and dimensionally stable is indeformable, anti-warpage, protection against the tide, waterproof, environmental protection, sound-absorbing noise control, suitable floor heating, heat conductivity heat-insulating, and coefficient of thermal expansion is little, stable, the installation simple and fast, bonding with the special environment protection floor glue, after 24 hours, just can use.
Below the present invention and common wooden floor comparative result:
By foregoing description, can further show that technical scheme of the present invention has following technique effect:
1, more economical, its materials are more saved than common solid wood, and same materials'use rate is enhanced about more than once than common solid wood.
2, noise reduction, the noise produced during use only has 30 decibels, than common wooden floor reducing noise over half.
3, protection against the tide, owing to using PVC to do bottom, the lines of S type for the section of limit, make moisture content be difficult to upload simultaneously, and more moisture protection is played in floor.
4, distortion is less, by groove, realizes cancelling out each other of stress, makes its distortion with the solid wood compound phase than beautiful, to have solved a great problem troubled the wooden floor user with it.
5, installation is more economical convenient, while usually using wooden floor to install, needs keel, uses the technical professional, floor of the present invention is installed simply a lot, does not need keel, thereby can save this mounting cost.
