Description

Interlocking tile flooring structure

This work relates to a floor tile structure, specifically a multi-layered, heterogeneous material floor tile technology consisting of a hard ceramic tile surface layer combined with a base layer of wood and plastic materials, which can be interlocked to form a sound-insulating structure.

In the construction industry, flooring is an indispensable building material. It is used in all interior and exterior spaces of buildings. The importance of flooring to architecture is akin to the relationship between skin and the human body, involving structural and safety considerations, functionality and purpose, environmental comfort, aesthetics and design, and even psychological and quality-of-life aspects.

Common flooring materials on the market can be broadly categorized into two types: "hard" and "soft." "Hard" materials include stone, ceramic, tiles, mosaic tiles, cement, and terrazzo, with stone including marble and granite. "Soft" materials include wood, composite wood, engineered wood, wood-plastic composite, plastic, and bamboo flooring. The choice of material depends on the specific space and usage requirements.

The aforementioned flooring materials, besides being used as a single material, also include flooring structures formed by "layering" or "mixing" multiple materials. This is primarily to leverage the combined properties of various materials to achieve better practicality or to address a deficiency inherent in a single material. Examples of flooring technologies using layering include composite wood or engineered wood; examples of flooring structures using a "mixing" method include terrazzo and wood-plastic composites.

Further analysis of flooring installation methods reveals several subcategories: Tile-Setting, Glue-Sown, Nail-Down, Floating, Click-Lock, and Loose. There are six or five methods, including "Tile-Setting," "Glue-Sown," and "Nail-Down." Among these, "Tile-Setting," "Glue-Sown," and "Nail-Down" are fixed flooring installation methods. As the names suggest, "Nail-Down" means the floorboards are directly nailed into the ground for fixation; "Tile-Setting" involves pre-applying mortar to the ground before gluing the floorboards in place; and "Glue-Sown" involves pre-applying adhesive to the ground before gluing the floorboards in place.

"Floating," "Click-Lock," and "Loose Lay" are all types of movable flooring installations. "Floating" and "Click-Lock" both use interlocking or snap-fit structures on the floorboards themselves, which are then glued together. The difference lies in the installation method: "Floating" uses adhesive to bond the joints or snap-fit areas, making the entire floorboard appear to float on the ground; "Click-Lock" does not use adhesive to bond the individual floorboards, which are placed separately on the ground. "Loose Lay"... Lay flooring involves laying a large area directly on the ground; this method is commonly used for installations like PVC mats or carpets. The aforementioned flooring installation methods are chosen based on factors such as the flooring's inherent properties, the available space, and the desired level of coverage and usage.

This work primarily focuses on the technical research of "tile flooring," a type of hard material made from materials such as stone, marble, granite, ceramic, or porcelain through sintering. In terms of installation, it is mostly fixed to the ground using a "tile-setting" mortar method. The advantages of "tile flooring" include waterproofing, moisture resistance, wear and scratch resistance, heat and fire resistance, good weather resistance, easy cleaning, a wide variety of colors and patterns, and a long lifespan. Disadvantages include a cold feel, high hardness, easy accumulation of dirt in the seams, high installation costs, and relatively heavy weight. Due to the aforementioned material characteristics and installation limitations of "tile flooring," it is commonly used in bathrooms, kitchens, entryways, living rooms, commercial spaces, balconies, and outdoor spaces.

Traditional tile flooring installation involves a "tile-setting" method, which is a highly technical construction technique. Examples of this method include Chinese Patent No. CN115045464, "A Method and Structure for Splicing and Laying Flooring with Stone or Ceramic Tiles," and domestic Patent No. 113111414, "Cement Bricks and Their Construction Method." The invention patent, as documented, reveals that traditional tile flooring installation involves various tasks, including the mixing ratio of cement and grout, mixing techniques, the speed required to complete the entire installation before the cement dries, tile cutting, neat tiling, and grouting. Therefore, experienced installers are essential. However, in recent years, there has been a shortage of skilled personnel for tile flooring installation, often resulting in situations where installers cannot be found. Furthermore, tile flooring installation generates significant waste, especially when renovating old tiles. This requires removing the old tiles, leveling the surface, and then laying new tiles, resulting in large amounts of waste such as cement bags, cement blocks, broken bricks, dust, and construction debris, leading to high waste disposal costs.

On the other hand, due to the hard texture of floor tiles, they inevitably generate significant noise from dropped objects, footsteps, or dripping water, especially in buildings where adjacent floors easily transmit sound to the floors below. Furthermore, amendments to domestic building regulations stipulate that 15cm thick concrete floors must achieve a noise reduction of over 17 decibels to comply with the legal limit of 58 decibels. Therefore, using floor tiles, due to their relatively poor sound insulation compared to other materials, necessitates the use of additional soundproofing technologies to meet regulatory requirements.

Most sound-insulating flooring on the market uses various "soft" or "hard" materials as the surface layer, followed by a sound-insulating layer, forming a multi-layered structure. The sound-insulating layer often uses foam or rubber materials for better sound insulation. This multi-layered structure is usually achieved by gluing the different materials together. Soft materials are often flexible and uneven, and when the surface layer or sound insulation uses thermoplastic or thermosetting materials, the gluing process often involves applying appropriate pressure under high temperature to firmly bond and fix the layers together using hot-pressing technology.

The aforementioned conventional soundproof flooring technology involves a multi-layered structure, such as the "Novel Tile Structure" patent disclosed in Domestic Patent No. 094222250. This technology uses thin, sheet-like boards as materials, which are then adhered to the surface of floor tiles. Its characteristic lies in the following: the thin boards, after being impregnated and glued, are arranged in a cross-grain pattern, placed directly on the floor tile surface, and bonded together with appropriate heat and pressure to form a solid tile board. After trimming and finishing, a moisture-proof wood-look tile structure is created.

Another known technology for sound-insulating flooring is the multi-layered structure, such as the invention patent disclosed in domestic patent No. 111123153, "Manufacturing Formula, Processing Method and Application of Environmentally Friendly Plastic Floor Tiles". Its processing steps include: providing an environmentally friendly manufacturing formula for plastic floor tiles as described in claims 1 or 2; and using a twin-screw extruder to set different mixing temperature zones, which include a feeding zone, a plasticizing zone, a compression zone, an exhaust zone, and a metering zone. The environmentally friendly manufacturing formula for the plastic floor tile is subjected to high-temperature mixing; and an extrusion die connected to the end of the aforementioned twin-screw extruder is used to mold the environmentally friendly manufacturing formula for the plastic floor tile obtained in the aforementioned mixing stage. The extrusion die has a horizontally extending extrusion channel, which is set with a plurality of different molding temperature zones in the horizontal direction. The extrusion die processes the environmentally friendly manufacturing formula for the plastic floor tile into a flat sheet core material with a predetermined thickness.

Another known technology for sound-insulating flooring is the multi-layered structure, such as the "Artificial Flooring" invention patent disclosed in Domestic Patent No. 108112050. This technology includes a board with a padding portion on one surface. The padding portion undergoes multiple electronic cross-linking foaming processes. When the board is laid on a base floor, the padding portion contacts the base floor, and the surface portion is bonded to the padding portion by heat or adhesive.

Furthermore, regarding the aforementioned conventional tile flooring, in addition to the problems of high technical difficulty, lack of professional manpower, large amount of waste generation, and high disposal costs during tiling installation, the use of materials such as stone, marble, granite, ceramic, or porcelain often results in considerable thickness and weight, making them difficult to transport.

Further examination of the sound insulation issues of the aforementioned common floor tile flooring reveals that due to its multi-layered, non-material bonding structure, the manufacturing process often involves high-temperature, pressurized bonding of thin sheets of different materials with the sound insulation layer. While waiting for the adhesive to cool and solidify, the process requires additional heating devices and fixtures. Furthermore, these heating devices are also highly energy-intensive, increasing carbon emissions and resulting in higher carbon tax costs. The heating process often causes plastic materials or organic solvent adhesives to... The release of toxic fumes has led to worker poisoning. Furthermore, even with foamed materials commonly used as sound insulation layers, the same bonding issues arise during the manufacturing process of the sound insulation layer itself. On the other hand, while multi-layered soundproofing flooring often features interlocking joints on the sides to address issues during cement installation, these interlocking joints are only present on two corresponding sides, not on all four sides, resulting in poor stability after assembly.

In view of the aforementioned problems with conventional "tile flooring" due to its mortar installation, multi-layer structure, and wear and tear, the inventor of this invention proposes a modular tile flooring structure and its manufacturing method that simultaneously solves these conventional problems, while also enhancing other functions and providing other new features.

In view of this, the interlocking tile floor structure disclosed in this invention includes: a tile layer; and a wood panel layer, which is formed by applying a water-based adhesive layer to one side of the tile layer and then bonding it to the tile layer. After being pressed under a predetermined pressure and for a predetermined time at room temperature, the tile layer and the wood panel layer are tightly bonded together. Each of the four sides of the tile layer has a flange-shaped tenon on two adjacent sides and a groove-shaped tenon on two other adjacent sides. The tenons are exposed on each of the tile and wood flooring layers. Each tenon and tenon can be interlocked with the tenons and tenons of another interlocking tile flooring; a sound insulation layer... The sound insulation layer is formed by applying a self-adhesive layer to one side and then bonding it to the wood panel layer. Slight pressure is applied at room temperature to ensure a tight bond between the sound insulation layer and the wood panel layer. This multi-layered structure is formed by bonding the tile layer, wood panel layer, and sound insulation layer together with water-based adhesive and self-adhesive layers under heavy pressure at room temperature. Combined with the interlocking design of the wood panel layer, this design can simultaneously solve related problems in masonry paving construction and achieve noise reduction, modularization, environmental protection, and thermal insulation effects. It is also easy and quick to maintain and replace, and has good water resistance, making the overall structure convenient and practical.

The main purpose of this creation is to provide a multi-layered tile flooring structure, consisting of tile layers, wood flooring layers, and sound insulation layers, bonded together with water-based adhesive and self-adhesive layers. The wood flooring layers feature interlocking tenons on all four sides, eliminating the need for cement paving and related problems, while simultaneously improving the stability of the tile joints and enhancing the adhesion.

A secondary objective of this invention is to provide a multi-layered structure for interlocking tile flooring. This structure is achieved by bonding various adhesive and self-adhesive layers under heavy pressure at room temperature. This ensures a stable bond between the tile layers, wood layers, and sound insulation layer. No heating is required during the bonding process, thus solving problems associated with hot-pressing. Furthermore, no organic toxic substances are released during the process, preventing worker poisoning.

Another objective of this creation is to provide a modular tile flooring structure, which employs a multi-layered design of tile layers, wood panels, and sound insulation layers, along with a mortise and tenon joint system. This design not only achieves sound insulation and noise reduction but also modularizes the overall structure for mass production.

Another objective of this invention is to provide a modular tile flooring structure whose sound insulation layer uses non-foamed materials such as rubber, cork, sugarcane fiber, thermoplastic (EVA), or mixtures thereof. This utilizes recycled or renewable plastics or natural materials, offering significant environmental benefits while also providing thermal insulation.

First, please refer to Figures 1-5. The interlocking tile flooring structure provided in this invention includes: a tile layer (10), and a water-based adhesive layer (20), a wood panel layer (30), a self-adhesive layer (40), and a sound insulation layer (50) sequentially attached to one side of the tile layer.

The tile layer (10) is a plate with a predetermined thickness and predetermined length and width dimensions.

The wood panel layer (30) is formed by applying a water-based adhesive layer (20) to one side and then bonding it to the tile layer (10). After being pressed under a preset time and pressure at room temperature, the tile layer (10) and the wood panel layer (30) are tightly bonded together. The wood panel layer (30) has flanges on two adjacent sides on each of its four sides. One of the tenons (31) has a protruding tenon, and the other two adjacent sides each have a recessed tenon (32). The protruding tenon (31) is exposed on each of the tile layers (10) and the wood panel layer (30). Each protruding tenon (31) and recessed tenon (32) can be interlocked with the recessed and protruding tenons (31)(32) of another interlocking tile floor.

The sound insulation layer (50) is formed by applying an adhesive layer (40) to one side and then bonding it to the wood panel layer (30). Slight pressure is applied at room temperature to ensure a tight bond between the sound insulation layer (50) and the wood panel layer (30).

By employing the aforementioned components, including the tile layer (10), wood panel layer (30), and sound insulation layer (50), and bonded together with the water-based adhesive layer (20) and self-adhesive layer (40) under heavy pressure at room temperature, a multi-layered structure is formed. Combined with the interlocking tenon and mortise design of the wood panel layer (30), this system simultaneously solves related problems in masonry paving construction, achieving noise reduction, modularity, environmental friendliness, and thermal insulation. It also offers simple and quick maintenance and replacement, along with good water resistance, making the overall structure convenient and practical.

To further understand the structural features, technical means, and expected effects of this creation, the usage of this creation is described as follows: The tile layer (10) of this creation can be made of one of the following materials: stone, marble, granite, ceramic, porcelain, etc.; the wood board layer (30) can be made of one of the following materials: log, polyurethane plywood, composite wood, etc.; the water-based adhesive layer (20) is one of the following adhesives: water-based polyurethane adhesive or water-based epoxy adhesive; the self-adhesive layer (40) is an adhesive formed by one of the following: polyvinyl chloride (PVC), polyacrylate (PAA), polyvinyl acetate (PVAc), polyurethane (PU), silicone adhesive, or a mixture of the above components.

In this invention, when multiple layers are bonded together, with each tile layer (10) and wood panel layer (30) bonded under gravity, the ambient temperature is around 25°C and the humidity is 60-70%. When bonding the wood panel layer (30) and sound insulation layer (50) together, with slight pressure applied, the ambient temperature is around 25°C and the humidity is 60-70%.

The sound insulation layer (50) of this invention can be made of one of the following materials: rubber, cork, bagasse, thermoplastic (EVA), or a mixture thereof. It can be used alone or in combination with two or more materials. The mixed portion can be a combination of rubber and cork, with the rubber percentage ranging from 80-90% and the cork percentage from 10-20%. Ideally, the rubber percentage should be 85% and the cork percentage 15%.

The finished interlocking tile floor structure of this creation has the following characteristics: the tile layer (10) is less than 6mm thick; the wood panel layer (30) is 6-8mm thick; and the sound insulation layer (50) is 2-5mm thick.

The splicing structure design of this creation is shown in Figures 3 to 5. Two adjacent sides are provided as protruding tenons (31), and the outward protrusion dimension of each protruding tenon (31) is set as (d1). The other two adjacent sides are provided as concave tenons (32), and the inward concave dimension of each concave tenon (32) is set as (d2). The value of the outward protrusion dimension (d1) in this creation is set to be greater than or equal to the inward concave dimension (d2). It is best if the outward protrusion dimension (d1) is slightly larger than the inward concave dimension (d2), with the difference being within the range of approximately 0.01~0.5mm. Referring to Figure 8, when the convex dimension (d1) is slightly larger than the concave dimension (d2), after the two finished floor tiles (A) and (B) are joined together, a gap (D) will be created between them. This gap (D) can be further filled with grout to prevent dust or moisture from entering the interlocking structure; or to provide elastic space for thermal expansion and contraction.

When laying this interlocking floor tile, please refer to Figures 6 to 10. First, place the first tile (A) on the ground. Then, place the second tile (B) with its tongue-and-groove (32) against the tongue-and-groove (31) of the first tile (A), so that the two tongue-and-groove (32) and tongue-and-groove (31) interlock, thus completing the splicing of the first tile (A) and the second tile (B). Next, place the third tile (C) with its tongue-and-groove (31) against the tongue-and-groove (32) of the first tile (A), so that the two tongue-and-groove (32) and tongue-and-groove (31) interlock, thus completing the splicing of the first tile (A) and the third tile (C). When assembling the fourth tile (F), the tongue and groove (32) of the fourth tile is aligned with the tenon (32) of the first tile (A), so that the two tongues (32) and tenons (31) interlock, thus completing the assembly of the first tile (A) and the fourth tile (F). Next, the tenon (31) of the fifth tile (E) is aligned with the tongue and groove (32) of the first tile (A), so that the two tongues (32) and tenons (31) interlock, thus completing the assembly of the first tile (A) and the fifth tile (E). This process is repeated until the entire floor is laid.

It's worth mentioning that this creative floor tile can be laid flat on the ground or used for raised floor installations, making it extremely practical.

This invention utilizes water-based adhesive layers (20) and self-adhesive layers (40) to bond together the tile layer (10), wood panel layer (30), and sound insulation layer (50) to form a multi-layered structure. Combined with the design of tongue and groove joints (32)(31) on the four sides of the wood panel layer (30), the overall technology achieves the following effects:

I. The floor tile system of this invention features a splicing structure with tongue and groove joints (32) and (31), combined with a multi-layered structure. The surface layer (10) is made of hard floor tile material. The overall structural design replaces the traditional cement-laying method with splicing, thus eliminating the need for cement paving and solving the problems associated with traditional mortar flooring construction, such as the need for specialized skills, labor shortages, large amounts of waste, and high transportation costs.

II. Utilizing the splicing structure of the concave and convex tenons (32)(31), its modular design allows for mass production and simplifies the splicing process, thus enabling non-technical users to assemble and lay the cement themselves. When cement workers are short-staffed, woodworking workers can also perform the work, or anyone can DIY the splicing and laying process, thereby solving the problem of frequent labor shortages among experienced cement technicians.

Third, the multi-layered structure of this creation includes the sound insulation layer (50), achieving sound insulation, vibration damping, and noise reduction effects.

IV. The sound insulation layer (50) of this invention is made of non-foamed material, with rubber, cork, or bagasse being the best materials. Recycled or recycled rubber can be used, while cork and bagasse are natural materials, thus offering environmental benefits. This addresses the problems of conventional foamed materials, which often involve reshaping the cushion, generating toxic gases during the manufacturing process, and consuming considerable electrical energy, thus lacking environmental friendliness.

5. By utilizing the sound insulation layer (50) as a non-foamed material such as rubber, cork, or bagasse, the tile flooring of this invention further enhances its thermal insulation properties, thereby achieving a heat insulation effect.

VI. The bonding and assembly of the various layers of the tile flooring in this invention employs a long-term heavy pressure method to ensure a stable bond between the tile layers (10), the wood panel layer (30), and the sound insulation layer (50). No heating is required during the bonding and assembly process, thus solving the problems associated with conventional hot-pressing processes, such as energy consumption, carbon emissions, and toxic organic solvent gases.

VII. This invention uses water-based adhesives and self-adhesives as the bonding agents for the various tile layers (10), wood panel layers (30), and sound insulation layers (50). The bonding process can be carried out at room temperature without heating, and no organic toxic substances are released during the process, preventing worker poisoning. Therefore, the bonding process achieves a non-toxic and environmentally friendly effect.

8. The adhesive used to bond the tile layer (10), wood panel layer (30), and sound insulation layer (50) together is a water-based adhesive. The water-based adhesive layer (20) and the self-adhesive layer (40) are formed using water-based adhesive and self-adhesive, possessing high water resistance with low water absorption, as well as strong extensibility and adhesion.

9. A self-adhesive adhesive is used for bonding the wood panel layer (30) and the sound insulation layer (50). This adhesive is not a curing adhesive, but rather gives the self-adhesive layer (40) flexibility, allowing for a more seamless bond between the wood panel layer and the sound insulation layer, and reducing the likelihood of cracking in the flooring.

10. The thickness of the tile layer (10) in this invention can be reduced to less than 6mm. Combined with the support of the wood panel layers (30) and the sound insulation layer (50), compared to conventionally thicker solid floor tiles, this invention not only achieves the same support as conventional methods, but also significantly reduces the weight of the entire floor, facilitating transportation and installation.

XI. The tile flooring of this invention features tongue and groove joints (32)(31) on all four sides, ensuring a secure fit around the assembled floorboards. Compared to conventional flooring with tongue and groove joints on only two corresponding sides, this design offers superior stability and reduces the likelihood of bulges or protrusions between floorboards.

12. Utilizing the structural design where each of the concave and convex tenons (32) and (31) has two adjacent convex tenons (31) and two adjacent concave tenons (32), during splicing, please refer to Figure 7. Align one convex corner (X) of the floor tile with one concave corner (Y) formed by the other two already spliced floor tiles, and then move it laterally to allow each convex tenon (31) to enter each concave tenon (32) for further locking. By aiming at a single position, unlike the familiar two-sided interlocking tenon structure, which requires simultaneous alignment of both sides of the floor tile during splicing, the alignment and locking time is greatly reduced. Therefore, the construction is simple, fast, and convenient.

Thirteen, the structural design of the concave and convex tenons (32) and (31) of each adjacent tile is such that, when removing the tile floor from its spliced state, please refer to Figure 10. While gently tapping the adjacent corner of each convex tenon (31), move it outwards towards the outer corner of each adjacent concave tenon (32). This allows for easy, quick, and convenient removal, enabling the repair and replacement of individual cracked tile flooring without the need to remove and replace all tiles.

In summary, the "interlocking tile flooring structure" disclosed in this invention provides a sound-insulating and easily interlocking tile flooring structure. The tile layers, wood panels, and sound-insulating layers are bonded together under heavy pressure at room temperature through adhesive and self-adhesive layers to form a multi-layered structure. The wood panel layer features a mortise and tenon joint design, which simultaneously solves related problems in masonry paving construction and achieves noise reduction, modularity, environmental friendliness, and thermal insulation. It also offers simple and quick maintenance and replacement, and good water resistance, making the overall design truly industrially practical and cost-effective. Furthermore, its structural composition has not been seen in any books or publicly available information, thus meeting the requirements for a utility model patent application.
