A kind of composite floor board
Technical field
The present invention relates to decorative building material technical field, particularly a kind of composite floor board.
Background technology
PVC floor is present popular a kind of decorative building material in the world, uses extremely extensive, has for various places such as indoor family, teaching building, office building, factory, supermarkets.PVC floor has a lot of advantage: easy to clean, easy maintenance, moistureproof and waterproof, antibacterial bacteriostatic, easily install, green non-pollution, belong to environment-friendly products, and pattern, pattern are selective many etc.But use PVC floor also to have shortcoming, construction basal needs is higher, and high-temperature resistance is poor, is very easily scratched by sharp weapon, and is not natural materials, does not meet the theme of present environmental protection.
Summary of the invention
The present invention proposes a kind of composite floor board, not yielding, comfortable durable.The technical solution adopted in the present invention is specifically achieved in that
The invention provides a kind of composite floor board, comprise floor board block and be located at the lock catch connecting device of described floor board block both sides, the bamboo that described floor board block comprises innermost layer moulds sandwich layer, adhesive-layer, plank layer and wearing layer, the both sides that described bamboo moulds sandwich layer are equipped with described plank layer, two-layer described plank layer and described bamboo are moulded sandwich layer and glued joint respectively by described adhesive-layer, and described wearing layer is positioned at outside every layer of described plank layer.。
Preferably, described lock catch connecting device comprises joint tongue and tongue-and-groove corresponding thereto.
Preferably, described joint tongue comprise projection and outside described projection on the fixture block that vertically extends, the draw-in groove that described tongue-and-groove comprises groove and in the middle part of described floor board block, side offered at described groove, described projection is corresponding with the size shape of described groove, and described fixture block is corresponding with the size shape of described draw-in groove.
Preferably, the shape of described projection and described groove is stairstepping.
Preferably, described groove is deepened gradually along the direction near described floor board block.
Composite floor board of the present invention have employed bamboo moulding material in sandwich layer position, moistureproof and waterproof, there is odor-absorbing, bactericidal properties, environmental protection is stable, cost is low.Have employed plank layer at skin, there is elasticity, not yielding, comfortable durable; In addition, composite floor board of the present invention have employed snap close and connects, and be connected firmly, difficult drop-off, is convenient to mat formation.

Detailed description of the invention
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing, make above-mentioned and other object of the present invention, Characteristics and advantages will be more clear.Deliberately do not draw accompanying drawing in proportion, focus on purport of the present invention is shown.
Fig. 1 is the lateral view of specific embodiment of the invention composite floor board.As shown in Figure 1, composite floor board of the present invention, comprises floor board block 10 and is located at the lock catch connecting device 11 of floor board block 10 both sides.The bamboo that floor board block 10 comprises innermost layer moulds sandwich layer 1, adhesive-layer 2, plank layer 3 and wearing layer 4.Bamboo is moulded sandwich layer 1 both sides and is equipped with plank layer 3, and plank layer 3 and bamboo are moulded sandwich layer 1 and glued joint respectively by adhesive-layer 2, and wearing layer 4 is positioned at the outside of every layer of plank layer 3.What bamboo moulded sandwich layer 1 employing is hollow section bar.In outermost wearing layer 4 employing is alundum (Al2O3) material.
Fig. 2 is the schematic perspective view of specific embodiment of the invention composite floor board.As depicted in figs. 1 and 2, lock catch connecting device 11 comprises joint tongue 5 and tongue-and-groove corresponding thereto 6.Joint tongue 5 comprise projection 5a and outside projection 5a on the fixture block 5b that vertically extends, the draw-in groove 6b that tongue-and-groove 6 comprises groove 6a and in the middle part of groove 6a closely plate 10, side offered.
Projection 5a is corresponding with the size shape of groove 6a, and the shape of projection 5a and groove 6a is stairstepping, and groove 6a deepens gradually along the direction of closely plate 10.Fixture block 5b is corresponding with the size shape of draw-in groove 6b, and the shape of fixture block 5b and draw-in groove 6b is cuboid.
Be understandable that, in the specific embodiment of the invention, the shape of projection 5a and groove 6a is stairstepping, but the present invention is not limited to this, and the shape of projection 5a and groove 6a also can be zigzag, or other shapes that can mutually mate.
Be understandable that equally, in the present invention, the shape of fixture block 5b and draw-in groove 6b and size are not only confined to the content of this specific embodiment, can also be other 3D shapes.
Two pieces of composite floor boards of the present invention, wherein the fixture block 5b of one piece of composite floor board is stuck in the draw-in groove 6b of another block composite floor board, and is pressed in the groove 6a of this another block composite floor board by the projection 5a of this piece of composite floor board, namely define snap close to connect, be connected firmly, difficult drop-off, is convenient to mat formation.And composite floor board of the present invention have employed bamboo moulding material in sandwich layer position, moistureproof and waterproof, there is odor-absorbing, bactericidal properties, environmental protection is stable, cost is low.Have employed wood material at skin, there is elasticity, not yielding, comfortable durable.
Set forth a lot of detail in the above description so that fully understand the present invention.But above description is only preferred embodiment of the present invention, the present invention can be much different from alternate manner described here to implement, and therefore the present invention is not by the disclosed concrete restriction implemented above.Any those skilled in the art are not departing under technical solution of the present invention ambit simultaneously, the Method and Technology content of above-mentioned announcement all can be utilized to make many possible variations and modification to technical solution of the present invention, or be revised as the Equivalent embodiments of equivalent variations.Every content not departing from technical solution of the present invention, according to technical spirit of the present invention to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belongs in the scope of technical solution of the present invention protection.
