Surface is referred to by multiple quarter-sawed lumber levels and is connect that the quarter-sawed lumber from top to bottom successively includes the hardened layer and bullet of integrally connected
Property layer, the density of the hardened layer is the 125%~135% of the density of the elastic layer.
The beneficial effects of the present invention are: hardening stage floor of the invention, by being arranged one layer firmly on the surface of quarter-sawed lumber
Change layer and elastic layer, both ensure that the good elasticity of quarter-sawed lumber, the premise of flexibility, adstringency, toughness, recovery and impact absorbency
Under, the surface hardness of quarter-sawed lumber is improved, the materials such as compression strength and the shear strength of stage wood floor surface are improved.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the quarter-sawed lumber is the axially cutting obtained plate of radius along log.
Beneficial effect using above-mentioned further scheme is: quarter-sawed lumber is centripetal axially cutting by using the radius along log
Obtained plate, make quarter sawing plate surface diameter line be in the direction of the force same density material, the homogeney of this material is big
The stability and crushing resistance on floor are improved greatly, while overcoming rotary-cut plate since floor surface fibre compact layer and unconsolidated formation are handed over
Mutually exist and resistance to compression coefficient is significantly different in the direction of the force, be easy pierce etc. drawbacks.
Further, the finger place of connecing for two quarter-sawed lumbers that phase coreference connects is in the zigzag being mutually twisted.
Beneficial effect using above-mentioned further scheme is: meeting place by the way that jagged finger is arranged, makes the engagement of finger-jointed plate
Effect is more preferable.
Further, one end of the quarter-sawed lumber is equipped with finger and connects protrusion, and the other end, which is equipped with, refers to that connecing protrusion is adapted with described
Finger connect groove, the finger, which connects protrusion and refers to, connects the both ends that groove is arranged symmetrically in the quarter-sawed lumber.

Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
Embodiment 1
As shown in fig. 1~fig. 5, a kind of stage timber floor of the present embodiment, is arranged in the upper surface of stage, by multiple quarter sawing
1 level of plate, which refers to, to be connect, and the quarter-sawed lumber 1 from top to bottom successively includes the hardened layer 14 and elastic layer 15 of integrally connected, described
The density of hardened layer 14 is the 125%~135% of the density of the elastic layer 15.
The stage timber floor of the present embodiment is referred to using multiple quarter-sawed lumber levels to be connect, and floor blank timber is greatly reduced
Fibre length or width thus greatly reduce the internal stress of floor blank, improve the stability on floor.In addition, due to tree
Carpentery workshop is nature growth-gen, necessarily has the natural flaws such as knot, color difference, medullary spots, small holes caused by worms, resin cyst, part be rotten, and is used
Finger, which connects horizontal spelling technique, to carry out choice collocation according to the wish of people, so as to greatly improve in solid wood stage timber floor
In quality and image appearance.By the way that one layer of hardened layer and elastic layer is arranged on the surface of quarter-sawed lumber, it both ensure that quarter-sawed lumber was good
Elasticity, flexibility, adstringency, toughness, under the premise of recovery and impact absorbency, improve the surface hardness of quarter-sawed lumber, improve
The materials such as the compression strength of stage wood floor surface and shear strength.

Obtained plate.Quarter sawing specifically refers to the radial direction along log 3 and the annual ring line 31 perpendicular to log carries out cutting materials.And
Most common is plain-sawed lumber, and plain-sawed lumber 2 refers to along perpendicular to the radial direction of log 3 and cutting along 3 annual ring line 31 of log
It is cut in line direction.Quarter-sawed lumber 1 makes by using the centripetal axially cutting plate obtained at least twice of the radius along log 3
The diameter line on 1 surface of quarter-sawed lumber is the material of same density in the direction of the force, and the homogeney of this material substantially increases floor
Stability and crushing resistance, while overcome rotary-cut plate due to floor surface fibre compact layer and unconsolidated formation interaction exist and in power
Direction on resistance to compression coefficient it is significantly different, be easy thorn etc. drawbacks.
Phenomena such as existing solid wood stage timber floor is commonly present stress concentration, and deformation probability is big.And length gets over length and width degree
It is more wide more be prone to bending, tile, the deformation such as cracking.Existing big blank is cut into small quarter-sawed lumber by the present embodiment,
For example, the blank that length is 2000mm is cut into the blank that length is 300mm~500mm, the blank that width is 120mm is cut
It is cut into the blank that width is 40mm~60mm, then the width and the lesser blank of length that are formed by cutting are referred to and connect one
It rises, greatly reduces the internal stress of original blank, improve the stability on floor.
The finger of the quarter-sawed lumber 1 of the present embodiment connects mode, and there are two types of specific embodiments, specific as follows shown:
Embodiment one: the finger place of connecing 11 for two quarter-sawed lumbers 1 that phase coreference connects is in the zigzag being mutually twisted.Zigzag
Finger connect place along the quarter-sawed lumber length direction arrange.Method is connect using the finger of such embodiment, makes two neighboring quarter sawing
The connection of plate more firm stable.Length direction arrangement zigzag refer to the place of connecing increase two neighboring quarter-sawed lumber connection it is long
Degree keeps connection more firm.
Embodiment two: one end of the quarter-sawed lumber 1 is equipped with finger and connects protrusion 12, and the other end, which is equipped with, connects protrusion with the finger
12 compatible fingers connect groove 13, and the finger, which connects protrusion 12 and refers to, connects the both ends that groove 13 is arranged symmetrically in the quarter-sawed lumber 1.It adopts
Method is connect with the finger of such embodiment, two neighboring quarter-sawed lumber 1 is made to facilitate connection.Finger described in present embodiment connects protrusion 12 1
Body is connected on 1 one end end face of quarter-sawed lumber and arranges along the length direction of the quarter-sawed lumber 1, connects protrusion along institute by that will refer to
The length direction arrangement for stating quarter-sawed lumber, keeps the connection of two neighboring quarter-sawed lumber stronger.
Finger in embodiment two connects protrusion 12 and is also possible to multiple one end being uniformly distributed and be integrally attached to quarter-sawed lumber 1
Columnar projections on end face.
The quarter-sawed lumber of the present embodiment can have drawn from, and Oregon is loose, and sanding paint can be used in the stage timber floor being finally spliced into
Packaging molding.The stage timber floor intensity of the present embodiment is high, toughness is big, stability is good.
