A kind of composite floor board
Technical field
The present invention relates to the decorative building material technical field, particularly a kind of composite floor board.
Background technology
The PVC floor is popular a kind of decorative building material in the world now, uses extremely extensively, is useful on the various places such as indoor family, teaching building, office building, factory, supermarket.The PVC floor has a lot of advantages: 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 the PVC floor that shortcoming is also arranged, the construction basal needs is higher, and high-temperature resistance is poor, very easily by sharp weapon, is scratched, 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 specifically is achieved in that
The invention provides a kind of composite floor board, the lock catch connecting device that comprises floor board block and be located at described floor board block both sides, described floor board block comprises that the bamboo of innermost layer moulds sandwich layer, adhesive-layer, plank layer and wearing layer, the both sides that described bamboo is moulded sandwich layer are equipped with described plank layer, two-layer described plank layer and described bamboo are moulded sandwich layer respectively by described adhesive-layer splicing, and described wearing layer is positioned at every layer of described plank layer outside.。
Preferably, described lock catch connecting device comprises joint tongue and tongue-and-groove corresponding thereto.
Preferably, described joint tongue comprises projection and the fixture block vertically extended on the described projection outside, described tongue-and-groove comprises groove and the draw-in groove of offering on side, described groove close described floor board block middle part, 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, described projection and described groove is shaped as stairstepping.
Preferably, described groove is deepened gradually along the direction near described floor board block.
Composite floor board of the present invention has adopted the bamboo moulding material in the sandwich layer position, moistureproof and waterproof, has that odor-absorbing, bactericidal properties, environmental protection are stable, cost is low.Adopt the plank layer at skin, there is elasticity, not yielding, comfortable durable; In addition, composite floor board of the present invention has adopted the snap close connection, is connected firmly, and difficult drop-off, be convenient to mat formation.
The accompanying drawing explanation
Fig. 1 is the lateral view of specific embodiment of the invention composite floor board;
Fig. 2 is the schematic perspective view of specific embodiment of the invention composite floor board.
The specific embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, it will be more clear making above-mentioned and other purpose of the present invention, Characteristics and advantages.Deliberately do not draw in proportion accompanying drawing, focus on illustrating purport of the present invention.
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, the lock catch connecting device 11 that comprises floor board block 10 and be located at floor board block 10 both sides.Floor board block 10 comprises that the bamboo of 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 is moulded sandwich layer 1 with bamboo and gluedd joint by adhesive-layer 2 respectively, and wearing layer 4 is positioned at the outside of every layer of plank layer 3.What bamboo was moulded sandwich layer 1 employing is hollow section bar.What at outermost wearing layer 4, adopt is the 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 comprises projection 5a and the fixture block 5b vertically extended on the projection 5a outside, and tongue-and-groove 6 comprises groove 6a and the draw-in groove 6b closely offered on plate 10 sides, middle part at groove 6a.
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 plate 10 closely.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 can be also 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 the big or small content that not only is confined to this specific embodiment, can also be other 3D shapes.
Two composite floor boards of the present invention, wherein the fixture block 5b of a composite floor board is stuck in the draw-in groove 6b of another piece composite floor board, and the projection 5a of this composite floor board is pressed in the groove 6a of this another piece composite floor board, formed the snap close connection, be connected firmly, difficult drop-off, be convenient to mat formation.And composite floor board of the present invention has adopted the bamboo moulding material in the sandwich layer position, moistureproof and waterproof, have that odor-absorbing, bactericidal properties, environmental protection are stable, cost is low.Adopt wood material at skin, there is elasticity, not yielding, comfortable durable.
A lot of details have been set forth so that fully understand the present invention in above description.But above description is only preferred embodiment of the present invention, the present invention can implement much to be different from alternate manner described here, so the present invention is not subject to the restriction of top disclosed concrete enforcement.Any skilled personnel are not breaking away from technical solution of the present invention scope situation simultaneously, all can utilize method and the technology contents of above-mentioned announcement to make many possible changes and modification to technical solution of the present invention, or be revised as the equivalent embodiment of equivalent variations.Every content that does not break away from technical solution of the present invention,, all still belong in the scope of technical solution of the present invention protection any simple modification made for any of the above embodiments, equivalent variations and modification according to technical spirit of the present invention.
