Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses a bamboo-wood composite floor's embodiment, in this embodiment, two bamboo-wood composite floor splice each other, these two bamboo-wood composite floor are first bamboo-wood composite floor 1 and second bamboo-wood composite floor 2 respectively, explain for example with the structure of first bamboo-wood composite floor 1 below, as shown in fig. 1 to 5, bamboo-wood composite floor, including the bamboo board 11 that from top to bottom stromatolite set up, timber base plate 13 and with bamboo board 11 and the adhesive layer 12 of timber base plate 13 adhesive connection, one side that timber base plate 13 is used for being connected with adjacent bamboo-wood composite floor is equipped with the concatenation strip 132 of outside overhang, the upper and lower both sides of concatenation strip 132 all are equipped with the constant head tank sunken to timber base plate 13 inboard, these two constant head tanks are last constant head tank 131 and lower constant head tank 132 respectively, another side that timber base plate 13 and concatenation strip 132 are relative is equipped with this side inboard sunken, A cooperation groove 1321 for supplying the concatenation strip 132 cartridge complex on the adjacent bamboo-wood composite floor, the upper and lower both sides of cooperation groove 1321 all are equipped with the constant head tank location complex's on the adjacent bamboo-wood composite floor location arch, these two location archs are last location arch 1311 and lower location arch 1331 respectively.

The depth of the matching groove is greater than that of the splicing strip 132 so that the two are matched to form a matching gap, specifically, the splicing gap 102 in the embodiment, and the depth of the positioning groove is greater than that of the positioning protrusion so that the two are matched to form a matching gap, specifically, the upper positioning gap 101 and the lower positioning gap 103.

In this embodiment, the overhanging end tilt up of concatenation strip 132 sets for the angle, and cooperation groove and concatenation strip 132 adaptation set up, and like this concatenation back concatenation direction slope sets up, and the structural stability who improves hookup location department is thrown off when being convenient for avoid the horizontal atress.

The lower side of the positioning protrusion below the wood substrate 13 is provided with an avoidance step sunken to the inner side of the wood substrate 13, the side face of the avoidance step spliced with the adjacent bamboo-wood composite floor forms an inter-plate gap 104 with an opening facing downwards, and the gap forms a ventilation groove to avoid ground moisture accumulation. Meanwhile, the upper parts of the two bamboo-wood composite floors are tightly attached due to the existence of the gap, so that the attachment degree is improved.

The downside of timber base plate 13 is equipped with the ventilation groove that extends along its length direction, and the concrete structure of ventilation groove is as follows: the ventilation slot includes the arc wall 135 that is in the upper portion and the rectangular channel 134 that is connected with the opening of arc wall 135, and the width of rectangular channel 134 is greater than the width of arc wall 135, avoids like this that the ventilation slot has great transition, avoids consequently causing timber base plate 13 to stress too big and the crackle appears.

the overhanging end of the splicing strip 132 is of a smooth transition structure, the shape of the bottom of the matching groove is matched with the shape of the splicing strip 132, the head of the positioning bulge is of a smooth transition structure, and the shape of the positioning groove is matched with the shape of the positioning bulge. The adoption of the smooth transition structure can lead the splicing strip 132 and the positioning bulge to have certain guiding function in the splicing process, thereby being convenient for installation.

The utility model discloses a bamboo wood laminate flooring splices the back, in the cooperation groove on the concatenation strip concatenation cartridge to the adjacent template substrate on the timber base plate, realize two bamboo wood laminate flooring's concatenation connection, and simultaneously, the constant head tank and the protruding location fit in corresponding location of both sides about the concatenation strip, make two firm concatenations of timber base plate together like this, because mosaic structure sets up on the timber base plate, avoid mosaic structure to cause the influence to the structural strength of adhesive layer and bamboo clapper, the concatenation strip simultaneously, it is protruding to fix a position, because positional relationship between the constant head tank forms dislocation structure, connection structure's stability has further been improved.

In other embodiments of the present invention, the splicing strips can be horizontally arranged or inclined downward; the ventilation slot can also be integrally arranged into an arc slot structure; the positioning bulge can also be arranged into a triangular structure; and an antibacterial layer, a moisture-proof layer and other structures can be arranged between the wood substrate and the bamboo board.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
