The purpose of this utility model is that the structure to above-mentioned existing composite floor board makes improvements, and a kind of low anti-deformation composite floor board of sensitivity that is out of shape is provided, to solve existing existing the problems referred to above of composite floor board.
The utility model is that the bottom surface (following laminar surface) at existing composite floor board is beneficial to bottom hydrofuge performance of ventilating near having additional in a peripheral week, also can regulate the peripheral groove of (reducing) distortion sensitivity.
Said peripheral groove is generally 10～30mm apart from floor periphery (edge) apart from height, and the degree of depth of groove is generally 2～4mm, and the groove face width is generally 3～10mm.
Composite floor board of the present utility model is owing to be provided with the groove that can regulate the distortion sensitivity in the bottom surface, increased the elasticity of floor periphery, like this when the floor produces distortion, just can play regulating action, that is to say, (reducing) distortion sensitivity is regulated voluntarily by these grooves in the good floor of amalgamation, thereby makes the seam crossing can be because of slit (slit increases) does not appear in floor deformation, and reaches the purpose that the protection seam is glued together waterproof; Simultaneously, these grooves can play the effect of exhaust passage, and the moisture between bottom surface, floor and ground is got rid of easily, have the effect that promotes bottom surface aeration-drying, have also reduced the distortion on floor from this respect.Under the not too big situation of ambient humidity; the floor makes moist on the shallow top layer of bottom surface; at this moment because the effect of bottom recesses; the swollen influence of contracting variation (distortion) butt joint that the floor is produced because of making moist obviously reduces; can avoid occurring slit and rugged defective, and can protect the seam gummed not split for a long time.
Composite floor board of the present utility model also can be set up the intermediate groove parallel with the floor minor face again in the middle of the bottom surface, can further regulate the distortion sensitivity of (reducing) floor like this along long side direction, and can further increase the aeration-drying between bottom surface, floor and ground, also can make the floor become softer and flexible simultaneously, contact with ground is steady and sure, increase the comfort of using.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the bottom surface structural representation of a kind of embodiment of the utility model composite floor board;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the B-B profile of Fig. 1;
Referring to figs. 1 through Fig. 3, composite floor board of the present utility model is elongated usually, and the size of its long limit and minor face is respectively usually: 1200～1300mm and 180～200mm.A long limit of one and a short side intermediate projections become tenon 1, and the tongue-and-groove 2 that recessed formation and tenon 1 are complementary in the middle of another long limit and another short side during installation, promptly is stitched together mutually by this tenon and tongue-and-groove between each floor.This composite floor board bottom surface near one week of periphery set peripheral groove 3 be preferably 10～20mm apart from the distance of floor periphery (edge), the degree of depth of this groove is preferably 2.5～3.5mm, the groove face width is preferably 7～9mm.The groove 3 on each limit can lead directly to floor edge and constitute " # " font (as shown in Figure 1), the floor is installed after, the groove 3 on each floor interconnects, and more helps the aeration-drying of bottom surface, floor.Under the situation that does not influence intensity, also can have additional one to some intermediate groove parallel 4 in the middle of this composite floor board bottom surface again with the floor minor face, the quantity of this intermediate groove can be determined according to the humidity situation of different environments for use and to the difference requirement of floor soft durometer, be generally 1～3, ambient humidity is big or when requiring floor softer, the quantity of intermediate groove 4 can be many slightly, otherwise then can be less if do not establish.Intermediate groove 4 is evenly distributed usually, and these intermediate groove two ends can pass straight through to floor edge (as shown in Figure 1).The degree of depth of intermediate groove 4 and groove face width can be identical with peripheral groove 3.
