In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of the utility model composite floor board;

Fig. 2 is the cross-sectional structure schematic diagram of Fig. 1;

Fig. 3 is the partial enlarged drawing of tenon among Fig. 2;

Fig. 4 is another structural representation of the utility model composite floor board.

The specific embodiment

Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.

Referring to Fig. 1, Fig. 1 is the structural representation of the utility model composite floor board, this composite floor board comprises panel 1 and substrate 2, substrate 2 is made up of central layer 21, at least two opposite edges of substrate 2 are provided with flanging 22, central layer 21 is arranged between the flanging 22, need to prove, when panel 1 be rectangular faceplate the time, the direction that flanging 22 is provided with is consistent with the length direction of panel 1, and in the middle of actual mechanical process, flanging 22 also can be provided with around substrate 2, can seal the outer of the uneven and sandwich construction of the substrate that forms with jigsaw 2 so on the one hand, make it neat appearance, improve the floor class, can make substrate 2 outers of every composite floor board form an integral body on the other hand, help being provided with tongue-and-groove and tenon, improve laying quality.Referring to Fig. 2, Fig. 2 is the structural representation of Fig. 1 cross section, for the polylith composite floor board being stitched together securely, wherein flanging 22 arranged outside at substrate 2 have tongue-and-groove 23, another flanging 22 arranged outside have the tenon 24 that is complementary with tongue-and-groove 23, and at the upper side of tenon 24 with downside is provided with the degree of depth and width respectively is the entomodont groove 241 of 0.3mm to 1mm, the degree of depth of entomodont groove 241 and the optimal cases of width are 0.5mm, as shown in Figure 3, Fig. 3 is the partial enlarged drawing of tenon 24, can make the joint of tongue-and-groove 23 and tenon 24 tightr by this entomodont groove 241, make the floor be not easy swelling, distortion, simultaneously more firmly firm for tongue-and-groove 23 is connected with tenon 24, can be between tongue-and-groove 23 and tenon 24 occlusal surfaces coated with adhesive.

Need to prove that panel 1, substrate 2 and central layer 21 all adopt the solid wood bar of identical material to make, the density of the composite floor board of making like this, moisture content and water imbibition etc. are all identical, make composite floor board more stable, reduce the dilation and the flexibility of composite floor board.In the middle of the concrete actual mechanical process, central layer 21 is solid wood scab or wound card, when central layer 21 is the solid wood scab, the wood grain circuit of panel 1 and the wood grain circuit of central layer 21 intersect mutually, cold pressing by adhesive at last or hot pressing is connected combination with panel 1 with substrate 2, so just formed the composite floor board of a two-layer aspect, composite floor board is attractive in appearance more generally can be provided with base plate below substrate 2 in order to allow, as shown in Figure 4, Fig. 4 is another structural representation of the utility model composite floor board, the composite floor board of this embodiment only embodiment in Fig. 1 increases a base plate 3, other structures are identical with Fig. 1, do not repeat them here, base plate 3 is solid wood jigsaw or plywood, when central layer 21 and base plate 3 are the solid wood jigsaw, and the wood grain circuit of panel 1, the wood grain circuit of central layer 21 and the wood grain circuit two two of base plate 3 intersect mutually, cold pressing by adhesive at last or hot pressing with panel 1, substrate 2 is connected combination with base plate 3, forms one three composite floor board of face layer by layer.

In sum, by on the edge of substrate, flanging being set, can seal the outer of the uneven and sandwich construction of the substrate that forms with scab, make it neat appearance, improve the floor class, simultaneously also can make the substrate outer of every composite floor board form an integral body, help on substrate, being provided with tongue-and-groove and tenon, finally the polylith composite floor board can be spliced and combined into a big composite floor board face, simple in structure and easy to use, simultaneously with the wood grain circuit of panel, the wood grain circuit of central layer and/or the wood grain circuit two two of base plate intersect mutually, make composite floor board be difficult for flexural deformation.

Above disclosed only is a kind of preferred embodiment of the utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.

Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
