The patent processes the concave portion and the convex portion on the bottom layer of the floor tile, which is not only complicated in processing, but also has high processing precision and easily affects the beauty after product combination. .

In addition, a plastic floor that has been spliced into a suspended structure (such as a utility model patent authorized by the applicant, authorized publication number: CN2791155Y, name: easy to splicing plastic floor) has been listed, although the above-mentioned situation has been largely solved. All kinds of problems, however, the plastic floor which is easy to splicing the suspension structure during use is prone to degumming and cracking of the hot melt adhesive due to the moisture moisture or the adhesive strength of the glue itself. Moreover, the plastic floor which is easy to be spliced and suspended structure is a whole after being paved, and the expansion and contraction phenomenon of the plastic due to the thermal expansion and contraction characteristics of the plastic is not conducive to a large change in the ambient temperature or a paving area. For larger occasions. This is a drawback that this structure is difficult to overcome.

SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to provide a plastic floorboard which can be When the production process is increased, the production process is optimized, the assembly and disassembly of the plastic floor are simplified, and the plastic floor can be used repeatedly, which greatly reduces the use cost, especially by optimizing the product structure and reducing the thermal expansion and contraction of the plastic.

Best embodiment

The present invention will be further described below in conjunction with the drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing the structure of a plastic floorboard of the present invention. The plastic floorboard of the invention is composed of upper, middle and lower three independent plastic floor blocks 1, 2, 3, wherein the middle floor block 2 is offset with the upper floor block 1 and the lower floor block 3 in the middle. The floor panel 2 is positioned to form the protrusion 4 and the groove 5; as can be seen from Fig. 2, the three are separate three-layer plastic floorboards, of course, each of the three layers of plastic floorboards can be complete. The floorboard, the so-called complete floorboard, also contains the wear layer, the printed layer and the bottom layer, or one or both of them are complete floor blocks, for example, only the upper floor block is a complete floor. Plate, this is also the style of the current ordinary floor. Different from the prior art, the present invention can adopt a floorboard which is complete in both upper and lower layers, that is, it can be used on both sides.

Of course, the plastic floorboards here, especially the upper and lower layers, may not be so-called complete floorboards, as long as they are provided with a patterned surface layer (relative to the printing layer in the prior art), that is, to meet the aesthetic needs. The definition of a so-called complete floorboard is not intended to be limiting, but merely a form that illustrates an existing single floorboard, so that the patterned facing of the present invention can be similar to a printed layer or similar definition in the prior art. can. Of course, when the upper and lower layers are provided with a facing layer, the facing layer should be located above and below the plastic floorboard.

Of course, a special case is not excluded, that is, the upper, middle and lower floorboard blocks 1, 2, and 3 all include only the bottom layer, which is also the minimum requirement of the present invention, that is, the three parties at least include the bottom layer, why must The requirement is mainly that the bottom layer has a certain thickness, and the combination of the three can naturally form the protrusions 4 and the grooves 5 required by the present invention, so that the definition and meaning of the bottom layer here are also relatively open. As long as a plastic layer having a certain thickness or a similar or replaceable layer is used, it is of course possible to adopt a multi-layer superposition, but it is within the scope of the present invention as long as the purpose and structure serve the same or similar functions.

Regarding the size of the three-layer plastic floorboard, of course, the thickness itself can be different, but in the middle The thickness of the interlayer floor block 2 has certain requirements, that is, it is necessary to meet the basic connection requirements, and of course, the thickness is appropriate, and is set according to actual needs. This is mainly because the thickness of the projection 4 of the present invention is the thickness of the intermediate floor panel 2, and the width of the recess 5 is also the thickness of the intermediate floor panel 2.

The length and width of the three-layer floorboard can be exactly the same. Of course, the ideal way is that if it is single-sided, that is, only the upper floorboard has a patterned surface layer, the upper floorboard 1 has a length and a width slightly larger than the intermediate layer. The panel 2 and the lower floor panel 3, or the upper and lower floor panels 1, 3 are larger than the intermediate floor panel 2. It is of course not excluded that the length and width of the intermediate floor panel 2 are slightly larger than the length and width of the upper floor panel 1, or greater than the length and width of the lower floor panel 2, or greater than the length and width of the upper and lower floor panels 1, 3.

Of course, the end of the lower floorboard can be engraved with a groove. The groove referred to in this paper refers to the removal of the surface layer, exposing the bottom layer, so the groove should be a very shallow groove, so that the surface is like a molding. The same, mainly for decorative purposes. In this way, when used on both sides, the lower floorboard will be used as the upper layer. At this time, the exposed color (generally the color of the bottom layer) is different from the color of the lower layer of the lower floorboard. In the middle, the groove can function similarly to the fillet. Of course, the end here generally means that the lower floor is located at the end of the adjacent sides of one side of the groove, that is, an L-shaped groove is formed.

The three-layer plastic floorboard can be bonded by a proprietary device using a hot-melt pressure-sensitive adhesive. Of course, a similar method can be adopted, so that the floorboard formed by the three is an integrally formed integral structure. In addition, the upper and lower floor panels 1, 3 may be simultaneously coated with a hot melt pressure sensitive adhesive, which of course should be the lower surface 6 of the upper floor panel 1 and the upper surface 7 of the lower floor panel 3, since this is mainly used for bonding, and additionally One of the advantages is that the formed groove 5 also has the above-mentioned hot-melt pressure-sensitive adhesive, and does not need to be additionally applied, so that when the two floor pieces are buckled, there is a glue bond between the groove and the protrusion. Increased connection strength. It is of course also possible to apply a hot melt pressure sensitive adhesive only on the upper and lower sides of the intermediate floor panel 2.

As shown in Fig. 3, it is an enlarged schematic view of the portion A in Fig. 1. The structure of the recess 5 can be seen more clearly in Fig. 3, and it can also be seen that on the side of the recess 5, a chamfer 9 is formed on the upper floor panel 1, and a lower floor panel 3 is formed. Chamfer 8. Here, the chamfers 8, 9 are mainly used for guiding in the subsequent combination. For example, when the two floor blocks are combined in Fig. 5, the chamfers 8, 9 can mainly introduce the protrusions 4 into the grooves 5 smoothly. It is of course also possible to chamfer the projections 4, which also serves as a guiding action. Regarding the dislocation of the intermediate floor panel 2 with the upper floor panel 1 and the lower floor panel 3, it means that the intermediate floor panel 2 is displaced in the same direction as the upper floor panel 1 and the lower floor panel 3 in the same horizontal plane, so as to form At the same time, the projections 4 and the grooves 5 are formed. Of course, it is not necessary to be completely consistent. The ideal state is the best and the best. Of course, it is also excluded from the case where the special case is not exactly the same. For the subsequently formed floor, the key point is that each plastic floor block is misaligned.

4 and 4A, 4B, and 4C are perspective views of the present invention. As can be seen from these views, the intermediate floor panel 2 and the upper and lower floor panels 1, 3 are L-shaped, and the protrusions are more conspicuous. 4 is L-shaped with respect to the floorboard, and of course the groove 5 formed at the same time is also L-shaped. Of course, the L-shaped misalignment is an ideal way. Of course, similar misalignment can also be adopted. The L-shaped dislocation is required. The main reason is that the L-shaped dislocation can be misaligned in both the length and the width, so that each floor piece can be realized. It is connected around, so similar structures that can achieve similar functions are possible. The above L-shaped dislocation is mainly caused by the fact that the three-layer floor block is a square floor block. If the three-layer floor block adopts other regular or irregular shapes, the corresponding misalignment shape can be adopted, especially considering the shape of the intermediate layer.

The floor of the present invention is a combination of floorboards according to the present invention, and the adjacent floorboards are joined by a groove of one of the floorboards and a groove of the adjacent floorboard. As shown in FIG. 5, it is a schematic diagram of a combination of two floorboards, wherein the floorboard 101 does not move, the floorboard 102 moves toward the floorboard 101, and then the projections of the floorboard 102 are inserted into the grooves of the floorboard 101. stand up.

6 and 7 are schematic structural views of a combination of six floorboards, wherein the relationship between the combinations can be seen from Fig. 7, from which it can be seen that there are six floorboards 103, 104, 105, 106, 107. The composition of 108, wherein the floor blocks 103, 104, 105 are longitudinally laid, and the floor blocks 103, 106, 107, 108 are laterally laid. Of course, the position shown in the figure is an ideal way. When actually laying, the floorboards 104, 105 and the floorboard 103 are misaligned, for example, the floorboards 104, 105 may be combined with the floorboards 103, 107 at the same time, or at the same time The panels 103, 106 are combined; or the floorboard 104 is combined with the floorboards 103, 107, and the floorboard 105 is combined with the floorboards 103, 106, primarily for the purpose of resisting contact gaps between lateral floorboards, such as floorboards. In combination with the floorboards 103, 107, the floorboard 104 can press against the contact gap between the floorboards 103, 107, which enhances the combined strength. Fig. 8 is an enlarged schematic view showing a portion B of Fig. 6. The combination can be seen more clearly by Fig. 8, wherein the first block is composed of the upper floor panel 11, the lower floor panel 31 and the intermediate floor panel 21, and the second block is composed of the upper floor panel 12 and the lower floor panel. 32 and the intermediate floor panel 22 are composited, wherein the first block is formed with a groove 5 and the chamfers 8, 9, and the second block is formed with a protrusion 4, and the combined shape of the two is as shown in FIG. The upper 4 is inserted into the recess 5, the upper floorboards 11, 12 are abutted together, and the lower decking blocks 31, 32 are staggered. When used as a double-sided floor, a groove may be formed at the end of the lower floor panel 31, that is, near the lower floor panel 32, so that the surface between the lower floorboards 31, 32 is formed like a molding when viewed from the outside. The groove is so as to cover a small gap between the lower floor blocks 31, 32.

Why is the floorboard of the present invention convenient to operate, and can be known by comparison with the prior art, for example, the Chinese invention patent application publication specification, the publication number is CN101029534A, and the patent name of the polyvinyl chloride floor tile and its paving method is similar. Structure, but since the concave portion and the convex portion are formed by processing, such a structure is difficult to control, and the width of the groove and the thickness of the convex portion of the present invention are both formed by the intermediate layer, so that as long as the thickness of the intermediate layer is uniform, basically It is possible to control the fit between the entire floorboards. Of course, it is very easy to do this without special machining accuracy requirements.

Further, the present invention is not only simple in processing but also easy to control in various combinations because it is a composite of three separate floor blocks as compared with the above prior art.

Therefore, it is required that each floor block size is matched, and each plastic floor block has the same misalignment, and the corresponding three layers of each plastic floor block have the same size. Of course, it will be different and will not affect the use, even deliberately different, and it can also be used to achieve the same effect.

And each floor block size is matched, as long as the processing technology and material selection of each floor block are made in accordance with the method of forming the floorboard of the present invention. Firstly, three plastic floorboards are selected. Secondly, three plastic floorboards are divided into upper, middle and lower layers, and grooves and protrusions are formed at the intermediate layer. The middle layer and the upper and lower layers are The same direction is misplaced.

In addition, there is another problem, that is, the materials of the upper, middle and lower floorboards 1, 2, and 3 are generally the same material, and of course, a compatible material may be selected according to specific conditions. Although the three layers in the drawing are labeled with different textures, it is only In order to indicate different layers, instead of indicating different materials.

In addition, in order to prevent thermal expansion and contraction, the groove lines may be respectively formed on the upper and lower floor blocks 1, 3, of course, for the aesthetic needs, generally on the lower surface 6 of the upper floor panel 1 and the lower floor panel 3 7 carry out the groove line.

Industrial applicability

Since the present invention is an improvement in the prior art, the existing three independent plastic floorboards are composited, and the composite floor is automatically formed with grooves and protrusions, so that the prior art can be overcome. Insufficient, and can be applied to mass production in industry.
