Description

Low stress composite floor board

Technical field

A kind of floor is the utility model is related to, more particularly relates to a kind of low stress composite floor board.

Background technology

The structure of composite floor board generally includes panel and beneath bottom plate above, and core is accompanied between panel and bottom plate Plate, core plate are to be formed with multilayer single plate through adhesives.The floor of this structure is in use due to the timber product of core plate Kind is different with machine direction, and there is larger internal stress, and easily spot slab warping deformation, influences appearance and make in use It is particularly evident in the case of being changed greatly with quality, especially temperature and humidity.

In the prior art, the patent document of Publication No. CN103669794 discloses a kind of low stress composite floor board, it is remembered Carry：Including panel above and beneath bottom plate, multilayer single plate is accompanied between panel and bottom plate through the more of adhesives The core plate of laminate composition, the floor of panel, core plate and bottom plate successively through adhesives growth bar shaped, the surrounding on floor are formed with The tongue and groove mutually spliced, it is characterized in that being formed with the in a row groove parallel with floor short side on the core plate.The invention passes through Slot on core plate, cut off the long fibre of veneer in the long side direction of floor, this just substantially reduces stress so that does not allow on floor It is yielding.But the technical solution causes core plate to be divided into polylith, and exist still there is defect after slotting on core plate Gap, the overall construction intensity of core plate substantially reduce, and when being subject to folding force, core plate easily produces bending at fluting on floor； 2nd, the floor does not have water-proof function, causes it easily to make moist, and influences the structural strength of core plate.

Utility model content

In view of the deficiencies of the prior art, the utility model provides a kind of low stress composite floor board, can both prevent floor from sending out Raw warpage, and the structural strength on floor can be increased.

To achieve the above object, the utility model provides following technical solution：

A kind of low stress composite floor board, including backsheet layer, panel layer and core layer, core layer are compound by polylith plates of solid wood Form, multiple row's grooves are offered in the core layer, filling plate is equipped with each row's groove；The core layer Upper and lower surface is equipped with waterproof layer.

Preferably, fixing groove is offered on the side wall of row's groove, the side wall of the filling plate is equipped with fixed strip, institute Fixed strip is stated to be assemblied in fixing groove.

Preferably, the fixing groove and fixed strip coordinate for swallow-tail form.

Preferably, the waterproof layer is polyurethane water-proof paint.

The advantages of the utility model is：1st, the setting of groove is arranged, the wood grain fiber of each plates of solid wood can be separated, to reduce The stress of core layer, alleviating core layer, there is a situation where warpage；2nd, the setting that plate is filled in groove is arranged, effectively can will arrange ditch Groove filling is full, to increase the structural strength of core layer, prevents floor by there is a situation where bend at row's groove during folding force；3、 The setting of core layer upper and lower surface polyurethane water-proof paint, may be such that the utility model has the effect of waterproof, prevents Core plate makes moist the situation that structural strength is lower；4th, the setting of fixing groove and fixed strip, may be such that the polylith core split by row's groove Closely connected between plate by filling plate, further to increase core layer overall construction intensity；5th, swallow-tail form cooperation can Further increase the bonding strength between fixing groove and fixed strip.

Embodiment

The utility model low stress composite floor board is further described by Fig. 1 to Fig. 2.

A kind of low stress composite floor board, including solid wood back panel layer 3, solid wood surface flaggy 1 and core layer 2, core layer 2 is by polylith Plates of solid wood is combined by viscose glue, and multiple row's grooves 7, length of multiple row's grooves 7 along floor are offered in the core layer 2 Direction spread configuration is spent, filling plate 4 is equipped with each row's groove 7, row's groove 7 is filled up；The core layer 2 Upper and lower surface is equipped with waterproof layer.

Further, fixing groove 6 is offered on two madial walls of row's groove 7, fixing groove 6 is along row's groove 7 Length direction extends, and is equipped with fixed strip 5 in the two side walls of the filling plate 4, the fixed strip 5 is assemblied in fixing groove 6.

Further, the fixing groove 6 and fixed strip 5 coordinate for swallow-tail form.

Further, the waterproof layer is polyurethane water-proof paint, and filling plate 4 is plastic plate.

The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
