Description
Technical field
The utility model relates to technical field of floor, in particular to a kind of composite floor board.
Background technique
Solid wooden compound floor is usually using the rare solid wood sawing wood skin of longitudinal texture as dash board, with the fast growing wood of cross grain
For backboard, the two is formed by hot pressing after assembly, is a kind of novel solid wooden compound floor, few, more environmentally-friendly with glue consumption,
The features such as warpage is not easy after mating formation at home and abroad has certain traction at present.Existing solid wooden compound floor mainly divides
Be two kinds: the first is laterally to put at the narrow flitch interval of the good fast growing wood of several prior sawings, after dash board hot pressing assembly, point
Sheet metal forming forms；Second is on the basis of the first, and long side two sides are hard miscellaneous by one longitudinal direction texture of joggle or bonding addition
Batten forms lock in the two sides of long side.
However, existing solid wooden compound floor haves the defects that certain, the first solid wooden compound floor: can only open flat
Button, it is difficult to lock fluting is realized, without bite force；Backboard is easy in the absence of external forces there are a large amount of transverse expansion joints
There is warpage in drying shrinkage bulking, and the gluing that can only suspend is mated formation, and the feature of environmental protection is poor, and can not secondary use；Backboard flitch texture is vertical,
Lumber fibre direction and processing and forming Tool in Cutting direction are inconsistent, easy overhauling (the especially back side), appearance matter after otch
It measures poor.Second of solid wooden compound floor: production technology is complicated, batch assembly low efficiency；Hardwood frame, it is at high cost.
Summary of the invention
The purpose of the utility model is to provide a kind of structures simply, easy processing fluting, the composite floor board for being not easy warpage.
To achieve the goals above, a kind of composite floor board provided by the utility model, including plate body, the long side of plate body two sides
It is respectively arranged with first connecting portion and second connecting portion on side wall, the first reinforcement block and second is provided on the bottom wall of plate body and is reinforced
Block, the first reinforcement block are arranged along the first long side of bottom wall, and the second reinforcement block is arranged along the second long side of bottom wall.
As seen from the above technical solution, by the way that the first reinforcement block and the second reinforcement block are arranged on the bottom wall of plate body, thus
First connecting portion and second connecting portion are reinforced, the warpage preventing performance of first connecting portion and second connecting portion is improved.
Further embodiment is that plate body includes dash board and backboard, and first connecting portion and second connecting portion are arranged on backboard,
The bottom of backboard is arranged in first reinforcement block and the second reinforcement block.
Further embodiment is, dash board is the veneer of sawing, the raw material of dash board in oak, elm or black walnut one
Kind.
As it can be seen that dash board is selected from some rare tree species, the aesthetics of composite floor board is improved.
Further embodiment is that backboard is spliced by muti-piece flitch, and the raw material of backboard is in pine, dragon spruce or poplar
One kind, there are expansion joints between adjacent flitch.
As it can be seen that backboard selects the quick growing species of trees, the cost of composite floor board entirety is reduced, the setting at expansion joint improves backboard
Anti- drying shrinkage bulking ability.
Further embodiment is 3 to 5 times of the thickness with a thickness of dash board of backboard.
Further scheme is that the first reinforcement block and the second reinforcement block are bamboo chip.
As it can be seen that the coefficient of shrinkage of bamboo chip is less than timber, toughness will be got well compared with timber, use bamboo chip can be effective as reinforcement block
Inhibit the buckling deformation of the first connecting portion and second connecting portion of backboard, and bamboo chip is cheap, it is at low cost.
Further embodiment is that the grain direction of bamboo chip and the grain direction of backboard are vertical.
Further embodiment is that bamboo chip passes through micro- carbonization treatment.
As it can be seen that bamboo chip is more preferable by micro- carbonization treatment rear stability.
Further embodiment is that the bottom of backboard is provided with the first holding tank and the second holding tank, the setting of the first reinforcement block
In the first holding tank, the second reinforcement block is arranged in the second holding tank.
Further embodiment is, first connecting portion includes the first recess portion of intralamellar part recess and prominent to backing plate outer of supporting or opposing
The first protrusion, second connecting portion includes the second recess portion and the second protrusion, and the second recess portion is corresponding with the first protrusion, and second is raised
It is corresponding with the first recess portion.
As it can be seen that first connecting portion and second connecting portion are set as the mode of lock connection, when substantially increasing Floor Covering
Bonding strength between adjacent composite floor board does not need suspension gluing, can secondary use.
