Description

Rubber-free floor block

Technical field

The invention relates to the field of floor technology, in particular to a glue-free floor block for splicing into a floor.

Background technique

Compared with wooden floors, tiled floors and laminate flooring, plastic flooring has the advantages of strong decoration, easy handling and construction, softness, comfort, wear resistance and easy replacement. Therefore, it is widely used as a high-end floor decoration material and has gradually replaced wood. Floors, tile floors and laminate flooring have become the trend of mainstream floor decoration materials, especially in developed regions such as Europe, America, Japan and South Korea. Plastic flooring is increasingly favored by consumers due to its many advantages. Plastic flooring varies according to the construction form It is usually made of plastic floor tiles or rolled plastic floor. During construction, the plastic floor tiles are assembled on the ground into a plastic floor or the rolled plastic floor is directly laid on the ground. Plastic floor tiles are lighter and more convenient than roll-shaped plastic floors For handling, construction and replacement, plastic floor tiles are more popular on the market.

However, the plastic floor tiles on the market are mostly single-piece structures. It is often necessary to bond the blocks and the blocks to the ground by means of glue. This increases the time and labor costs of construction, and on the other hand Glue often contains environmentally unfriendly ingredients, which is not conducive to The environmental protection of the plastic floor, and the adhesive is prone to degumming after prolonged aging, affecting the use of the plastic floor. In addition, the plastic floor block in the form of a single piece of structure is easy to be displaced relative to the structure due to its structural factors, and the gap is opened on the floor. After long-term thermal expansion and contraction, it is prone to deformation or warping and arching. Therefore, the actual use effect of the plastic floor panel which needs to be adhered by means of adhesive bonding is not satisfactory.

In order to optimize the use effect of the plastic floor panel in the form of single-piece structure, the insiders including the applicant started from the structure and materials of the plastic floor block, and carried out more research and improvement to try to solve the plastic floor of the single-piece structure. spell Various defects in the block. For example, some people in the industry make glue-free plastic floor blocks by setting various structural forms of locks on the plastic floor blocks, using the locks to achieve the splicing between the blocks, and setting the rubber-free plastic floor with the locks. Piece Although the tiles can be relatively stably spliced without using glue, the construction difficulty and the production cost are increased, and the warpage or arching problem is not well solved. For another example, ZL200820117527.2 proposes a thermoplastic elastomer The plastic floor is assembled, including a substrate and a panel which is overmolded on the surface of the substrate, and correspondingly disposed trapezoidal ridges and tongues are arranged on opposite sides of the substrate, and mesh ribs are arranged on the back surface of the substrate. ZL200920156496.6 proposes a plastic The floorboard is composed of three layers of upper, middle and lower plastic floorboards. The middle layer and the upper and lower floorboards are dislocated in the same direction, forming protrusions and grooves at the intermediate layer, and the middle layer and the upper and lower layers. The plate is L-shaped. The knot of the above two patents The structural improvements enable the splicing of the floor without the use of glue, and all claim to solve the problems of deformation, strain, warpage and displacement. But in fact, the two patents are still structurally improved on the plastic floor tiles in a monolithic structure, due to Due to its structural factors, the technical solutions of the two patents in the form of single-piece structure have not completely eliminated the problems of deformation, strain, warpage and displacement, and because of the matching trapezoidal tenons And the gutter or the middle layer The L-shaped dislocation setting with the upper and lower floor panels increases the production cost.

As an effective method to solve the above problems, the applicant has made a patent application (patent number: ZL201110083685.7) entitled "A self-sinking adsorption block plastic floor" on April 2, 2011 after long-term research. Through plastic The scientific design of the rubber floor structure and the raw materials for the production makes the plastic floor not easy to slide relative to the ground without using the adhesive layer, and the use of the adhesive layer is omitted to prevent the adhesive layer from being degummed after prolonged aging. It has significantly improved the environmental protection of the plastic floor, and further solved the problems of deformation, warpage and displacement, and improved the use effect of the plastic floor. However, the applicant has completely solved the above problems on the basis of the patent number: ZL201110083685.7. Further research on the case found that it is more difficult to completely solve the deformation, strain and warpage without any increase in manufacturing cost and construction difficulty on the improvement of the structure or the production material of the rubber-free plastic floor block based on the single-piece structure. And shifting issues. Therefore, it has been researched to replace the plastic-free plastic floor block of other structural forms of the rubber-free plastic floor block in the form of a single-piece structure, which can completely solve the deformation, the slit and the warp without increasing the manufacturing cost and the construction difficulty. The effective way to solve problems such as songs and shifts.

Summary of the invention

In view of this, the technical problem to be solved by the present invention is to provide a glue-free floor panel which can completely solve the problems of deformation, strain, warpage and displacement without increasing the manufacturing cost and the construction difficulty.

In order to solve the above technical problem, the technical solution provided by the present invention is: a glue-free floor panel comprising a plurality of floor strips, the floor strips comprising at least a bottom layer and a surface layer, and the bottom layer of each floor strip is connected and surfaced. There are slits between the layers, and the same side end portions of the floor strips are provided with a right-angled trapezoid or an isosceles trapezoid. A tongue-and-groove groove is formed between the tenons, and the lower bottom edge of the tenon is provided with a sloped surface, and the lower bottom edge of the tongue-and-groove is provided with a beveled surface which can be matched with the inclined surface.

One of the main innovations of the present invention is to creatively adopt a plurality of floor strip block forms instead of the conventional one-piece structure form, and overcome the structurally isolated and unconnectable defects of the single-piece floor block. The joint between the plurality of floor strips makes the glue-free floor block a stable whole and is not easy to slide relative to the ground to generate displacement. At the same time, it is ensured that the slits are generated without relative displacement between the floor strips.

The number of floor strips included in the plurality of floor strips may be determined according to actual needs. For example, a piece of glue-free floor block may be composed of two floor strips, or may be composed of three or more floor strips. However, when a rubber-free floor contains a small number of floor strips, it is relatively more convenient for handling and construction. Of course, in actual production, each piece of glue-free floor is more suitable to be made to contain an even number of floor strips.

Another major innovation of the present invention is that the floor strips are joined by a bottom layer with a seam between the facing layers of the floor strip. This makes it possible to fasten and connect the floor strips in a single unit, and to reserve appropriate gaps between the surface layers. When the local slats are thermally expanded and contracted, the connection of the bottom layer keeps the floor strips flat. Stable, the seam between the surface layers can eliminate the volume difference caused by thermal expansion and contraction, so as to avoid the deformation, strain and warpage of the floor tiles.

The inventor has found through a lot of experimental research that the width control of the slit has a great influence on the actual use effect of the floor panel. The excessively wide slit will leave too much slit on the surface of the floor panel, and it is easy to hide the sundries or Water marks, and is not conducive to the finishing of the beautiful, too narrow slits can not better eliminate the volume deviation caused by thermal expansion and contraction, there are hidden dangers of deformation or warpage of the floor tiles. Therefore, the inventors have experimentally proved that the width of the slit should be controlled to 0.1-2 mm, and 0.1-0.5mm is the best, and the slits in the width range can better eliminate the volume difference caused by the thermal expansion and contraction of the floor strips, and do not cause a large slit between the surface layers. Conducive to the overall aesthetic and use of the floor.

The slit can be formed by cutting with a die. When cutting, it is necessary to strictly control the cutting depth of the die and the thickness of the die. The depth of the cut should correspond to the depth of the slit, and the thickness of the blade should be predetermined. The slot widths match. If necessary, the slits can also be replaced by strip indentations, which mainly serve to optimize the aesthetic effect.

Another main innovation of the present invention is that the same side end portion of the inter-floor floor strip is provided with a right-angled trapezoid or an isosceles trapezoid, and a tongue-and-groove joint is formed between the tenons, and the tenon is formed. The lower bottom edge of the gutter is provided with a sloped surface, and the lower bottom edge of the gutter is provided with a beveled surface which can be matched with the inclined surface. By providing a right-angled trapezoidal or isosceles trapezoidal ridge and a tongue-and-groove matching groove, the structural features of the right-angled trapezoid or the isosceles trapezoid can be used to securely fasten the floor tiles to prevent the floor tiles from being spliced together. Relative displacement. The inventor has learned through research that the horizontal striking limit that can be withstood by the buckle after the buckle is buckled is 15 kg, and the present invention adopts a plurality of floor strips and a floor strip. The block is provided with a right-angled trapezoidal or isosceles trapezoidal ridge and a groove to realize the fastening, and the buckle structure formed after the buckle can withstand the horizontal tensile force corresponding to the tensile strength of the floor block, which is far beyond 15 kg. Horizontal pull. By providing a bevel on the periphery of the tenon and a beveled surface that can be mated with the bevel on the periphery of the gutter, the bevel of the beak can be inserted into the underside of the bevel of the gutter when the floor is spliced, thereby The bevel is hidden, on the one hand, it can eliminate the joints and gaps caused by the joint of the tongue and the groove, so that the floor after the splicing is smoother and more consistent, preventing the edge of the floor block from arching, or the warpage and protrusion of the floor block itself. The phenomenon is beneficial to enhance the overall aesthetic effect; on the other hand, the arrangement of the inclined surface and the inverted inclined surface increases the friction surface between the convex and the tongue groove, which can further strengthen the joint stability between the two, thereby ensuring the between the floor blocks. Do not slide relative to each other.

The inventor discovered through research that when actually implemented, The glue-free floor tile can be made into at least two forms: the first is that the adjacent floor strips are of different widths, and the two adjacent floor strips are the tenons on the first floor strip. The same size as the tenon on the second floor strip, and the tenon on the first floor strip and the tenon on the first floor strip and the floor strip on the first floor strip The groove formed by the tenon is matched; the second is that the adjacent floor strips have the same width, and the tenons on the adjacent floor strips are different in size, but the tenons formed on the inter-floor strips The slots match the tenons on the inter-floor strips.

The length, width and thickness of the floor strips are determined according to actual conditions, but the thickness is generally controlled to be 2 mm to 5 mm, and the length is generally 50 cm to 200 cm, and the width is preferably 5 cm to 30 cm.

The bottom layer and the top layer of the present invention are closely pressed, laminated or composited, that is, the bottom layer and the top layer should not be easily torn. The bottom layer and the top layer are preferably plastic layers, but not limited to plastic layers, and may also be wood layers. , composite layer. And according to actual needs, The bottom layer and the top layer may respectively comprise a multi-layer structure, and other functional layers may be disposed above or below the bottom layer or the top layer, and between the bottom layer and the surface layer. For example, a soft layer and/or glass may be disposed under the bottom layer. The fiber cloth layer, or the bottom layer contains a soft layer and/or a fiberglass cloth layer. The soft layer can make the floor strips have fatigue resistance and elasticity, and the glass fiber cloth layer can improve the tear resistance and the folding resistance of the floor strips, thereby improving the durability of the floor blocks and prolonging the service life. For example, a pattern layer may be disposed on the surface layer to enhance the aesthetic effect, or an iron powder layer may be added between the bottom layer and the surface layer, or the bottom layer may include an iron powder layer to increase the self-weight of the floor strip itself, thereby Enhance the adsorption to the ground. The number of layers of the floor strips is not limited according to actual needs. For example, the floor strips may be two, three, four, five, six or even more layers.

In actual production, the inclination angle of the inclined surface and the inclined inclined surface is also emphasized. For example, the inclined angle of the inclined surface is preferably set to be at an angle of 5-85 degrees from the bottom surface of the bottom layer to connect the end of the convex portion to the underside of the groove. It can solve the problem that the end of the block is easy to be erected and arched when the traditional floor splicing is spliced, and the compact and flat splicing of the corresponding floor strips on different floor slabs is realized, thereby facilitating the optimization of the use effect of the spliced floor and Overall aesthetic effect. When the inclined angle of the inclined surface is set at an angle of 5-85 degrees from the bottom surface of the bottom layer, the inverted inclined surface corresponds to an angle of 5-85 degrees with the ground, so that the end portion formed by the tenon can be formed with the groove. The 空 shaped empty groove matches. The angle of inclination of the slope is more preferably set at an angle of 15-45 degrees from the bottom surface of the bottom layer, and the slope of the angle of 15-45 degrees is better hidden under the slope.

The above-mentioned inclined surface and the inverted inclined surface can be formed by cutting by a die. When cutting, attention should be paid to the control of the cutting angle of the die, that is, the blade inclination angle of the die should correspond to the preset inclination angle of the inclined surface and the inverted inclined surface.

As a further preference, the upper bottom edge of the tenon is integrally connected to the end of the floor strip. So that the longer lower bottom edge faces outward, the width of the tenon is gradually narrowed from the inside to the outside, and the width of the gutter is gradually widened from the inside to the outside, which is more advantageous when the tenon is combined with the gutter. The two are tightly joined to enhance the secure splicing between the floor tiles.

The base angle of the right angle trapezoid or the isosceles trapezoid may be any acute angle less than 90 degrees, but preferably 60-89.9 degrees, in the range of 60-89.9 degrees, when the angle of the bottom angle is larger, on the one hand, it is more advantageous for splicing. The overall aesthetics of the rear floor, on the other hand, saves the material that needs to be removed when forming the bottom corner.

By performing the above structural improvement on the floor panel, the problems of deformation, strain, warpage and displacement caused by the conventional floor panel can be completely solved without increasing the manufacturing cost and the construction difficulty. The structure of the floor block is spliced, and the structure is stable, durable, comfortable, and beautiful. Due to the seemingly simple structural improvement described above, the problems of the conventional floor tiles are overcome in one fell swoop, so that the cost of retrofitting for overcoming the problems of the conventional floor tiles can be greatly reduced, for example, no locks need to be provided; The upper and lower floor panels are dislocated in the same direction, and the protrusions and grooves are formed at the intermediate layer position, and the middle layer and the upper and lower floor panels are L-shaped dislocation; no reinforcing ribs need to be provided; the amount of iron powder can be reduced; It can create conditions for reducing the manufacturing cost of floor tiles, and at the same time simplify the production and construction process of floor tiles and reduce the difficulty.

As a further technical improvement, the bottom surface of the bottom layer is provided with a non-slip pattern, or the bottom layer is a anti-slip film provided with a non-slip pattern, or the bottom surface of the bottom layer is bonded with a anti-slip film with a non-slip pattern to further secure the floor. There is no relative displacement between the blocks, while preventing the displacement of the floor tiles relative to the ground. The anti-slip film is preferably a plastic anti-slip film, and the PVC anti-slip film is preferred. This is because the PVC anti-slip film has better toughness and elasticity, which can further improve the tear resistance, folding resistance and resilience of the bottom layer, thereby enhancing the foldability of the floor tile and prolonging its service life.

The anti-slip pattern may be any regular or irregular pattern, for example, the anti-slip pattern is a mixture of one or more of a stripe, a wave pattern, a ring pattern or a polygon pattern pattern. Or the anti-slip pattern is a mesh anti-slip pattern, wherein a mesh stop-slip pattern is preferred, and the grid of the grid anti-slip pattern is a regular polygon grid with a groove at the center.

The groove may be a groove having a circular, prismatic, regular polygonal or elliptical cross section, but is preferably a groove having a circular cross section. The regular polygon grid is an equilateral triangle lattice, a square lattice or a regular hexagon lattice.

Each side of the grid of the grid stop-slip pattern is provided with a through-port, so that the grid-stop-slip pattern is an open grid stop-slip pattern in which the grids are connected to each other and communicate with the outside. The use of the open mesh stop-slip pattern is based on the permeability and water permeability required in actual use. The grids of the mesh stop-slip are connected to each other and communicate with the outside, so that when there is moisture or air under the floor, Moisture or air circulates between the grids and can eventually be discharged outside the floor, thereby avoiding moisture or air stagnation caused by moisture or air stagnation, causing the floor to erect and slide, and enhancing the adsorption force of the floor tiles on the ground.

Compared with the prior art, the present invention has the following advantages:

1. The invention adopts a plurality of pieces of a plurality of floor strips to replace the traditional single-piece structure form, and overcomes the structurally isolated and unconnected defects of the single-piece floor panel, and the plurality of floor strips The joint between the two makes the glue-free floor block a stable whole, and it is not easy to slide relative to the ground to generate displacement. At the same time, it is ensured that the slits are generated without relative displacement between the floor strips.

2. The floor strips of the present invention are connected by the bottom layer, and the surface layers of the floor strips are provided with slits, so that the floor strips can be tightly connected and integrated, and can be reserved between the surface layers. When there is a proper gap, when the local slats are inflated and contracted, the connection of the bottom layer keeps the floor strips flat and stable, and the gap between the surface layers can eliminate the volume difference caused by thermal expansion and contraction, thereby avoiding The floor tiles are deformed, pulled, and warped.

3. The invention adopts the structural features of a right-angled trapezoid or an isosceles trapezoid by using a tenon with a right-angled trapezoid or an isosceles trapezoid and a tongue-and-groove trapezoid, and the floor panel can be firmly fastened to eliminate the floor fights. The relative displacement between the blocks. And by providing a bevel on the periphery of the tenon and a beveled surface which can be matched with the bevel on the periphery of the gutter, the bevel of the tenon can be inserted into the underside of the bevel of the gutter when the floor is spliced, thereby Concealing the bevel, on the one hand, eliminates the seams and gaps created by the engagement of the tongue and the tongue and groove, making the floor after the splicing smoother and more consistent, preventing the edge of the floor panel from arching, or the floor panel itself being warped and protruding. Such phenomena are beneficial to enhance the overall aesthetic effect; on the other hand, the arrangement of the inclined surface and the inverted inclined surface increases the frictional surface between the convex and the groove, which can further strengthen the joint stability between the two, thereby ensuring the floor block. There is no relative sliding between them.
