The present invention relates to a flooring construction method and flooring, and more particularly, to a method that can be installed so as not to be stepped or gaps between the upper surfaces of the flooring to be constructed, and a flooring preferred for such a construction method.

In general, the flooring is constructed by combining or bonding a plurality of flooring. Such flooring materials include, firstly, non-flexible materials such as natural wood, plywood, MDF, HDF, magnesium board, fibrous lightweight cement, and inorganic board, which have higher hardness and elasticity than natural wood. In addition, the flexible flooring material has a small elasticity, most of which is PVC, and there are deco tiles, deluxe tiles, wood tiles, and floor coverings.

Floor finishes used on the floor of a building are classified into types made of flexible materials, those made of non-flexible materials, and made of plastic and natural materials.

The flexible material is made of artificial resin (PVC), which can be rolled into a film or a thin plate, and printed on various patterns on one side, or a piece of paper veneer. Are made in the form of The flooring of this flexible material is artificial resin (mostly PVC type) and has the disadvantages of low strength, short life span, high shrinkage expansion and temperature, low thermal conductivity, and burning of flammable materials in case of fire and toxic gas release. The advantage is that the surface printing is very easy and the material is made of artificial resin, so it is easy to mass-produce and very flexible, so it can be easily attached to the curved floor without any step with other floor materials on the side. Such construction is very easy and corresponds to a great advantage in the commercial aspect.

Non-flexible flooring materials are typically wooden floors, which have printing paper or veneer on one side of plywood, UV coated on the surface, and have grooves and protrusions to fit with the flooring material on the side. In construction, the groove and the projection are fitted so that the top plate of the flooring material corresponding to the side does not generate a step, and is precisely fitted. In addition, depending on the material, the construction method is applied by applying an adhesive to the bottom of the base. The disadvantage of plywood flooring as a non-flexible flooring material is that the main material is wood, which is a flammable material in case of a fire. When the minimum thickness of wood is more than 8 mm when installed on the floor heating surface, the thermal conductivity is greatly reduced. As another non-flexible flooring, reinforcement floors are formed by impregnating printing paper and melamine with high temperature and high pressure on the upper surface of a plate made of wood powder powder at high pressure, and then forming grooves and protrusions on the side for mechanical bonding ( Uni-click) is relatively easy to construct. In addition, due to environmental problems, it is difficult to cut wood, and the price of plywood is increased, and all the parts of the wood are made of wood powder, which can be made at a much lower price than plywood flooring by using materials efficiently. The disadvantage is that it is very weak against water and moisture. When water is applied, the volume increases and breaks, and when exposed to moisture, the overall length increases, which is several times greater than that of the same laminated material. For this reason, the reinforced floor cannot be glued to the floor with adhesive and should be removed from the wall by 10 mm-20 mm, taking into account its elongated length. Since there is a distance from the floor, when walking after construction, the sound of footsteps is bumpy and bad.

In the above description, all of the flooring material of the flexible material means a flooring material which is applied by directly attaching the adhesive to the base of the floor without grooves or protrusions. In addition, the non-flexible flooring material has its own elasticity, so it is difficult to construct only the adhesive on the floor base, and thus means a flooring material using a method of fitting with grooves and protrusions on both sides. This is because the flexible flooring material is flexibly bent with a slight adhesive force and adheres to the floor even if the base material is curved, but the step material does not occur even when the base material is slightly bent. Because it can not be used.

Therefore, in order to fit the upper surface of the non-flexible material with high elasticity without any step, the groove and the protrusion must be precisely processed on the side by a precision processing machine such as CNC. In addition, the projection formed on the side should be more than a certain thickness in order to withstand when more than 100 kg of people stepping on the foot, plywood floor is 8 mm or more, reinforcement floor is used more than 7 mm. Due to the thickness of this limit situation, when the non-flexible wood material is installed on the floor of the floor heating area, the thermal conductivity is low, the heating of the room is not good, there is a disadvantage that a lot of energy is consumed. In addition, if the step is more than 0.2 mm, the human skin may be in contact with the wound and hurt, so it is necessary to go through many processes to make grooves and protrusions with expensive CNC equipment.

1 is a cross-sectional view showing a construction method of a conventional flooring material. Figure 1a is a cross-sectional view of the construction of the flexible flooring, Figure 1b is a cross-sectional view showing the construction of the laminate flooring, and Figure 1c is a cross-sectional view showing the construction of the reinforced floor.

In FIG. 1A, the flooring material 10a is flexibly generated well and flexes well according to the shape of the curved base end, and is then bonded to the bottom base end 20 using the adhesive 30 as it is. In FIG. 1B, the flooring material 10b is weakly flexible as plywood flooring and has a strong elasticity, thus making it difficult to match the step between the flooring material 10b as an adhesive, so that the stepping is made using the protrusions 12 and the grooves 11 and the adhesive 30 is adjusted. It is constructed on the base 20 by using. In Fig. 1c, the flooring material 10c has a weak flexibility as a reinforcement floor and a strong elasticity, so that it is difficult to match the step between the flooring material 10c as an adhesive, so that the step 12 and the groove 11 are used to fit the stepping step without the adhesive base 20. Install on

The warpage is well generated and bent well according to the shape of the curved base end, which is then bonded to the bottom base end 20 using the adhesive 30 as it is.

In order to solve such a problem, it is desirable to provide a method for constructing the top plate without the grooves and protrusions precisely machined by the CNC so as not to occur. However, even if a skilled engineer makes the ground floor of the building's cement floor, it is difficult to make a perfect flat surface, so all the curves exist. In addition, no matter how well-made flooring flooring is cut to the commonly used size (60 × 300 ~ 400 × 1200 mm) and placed on the floor in the free state, the bending of about 1 mm-10 mm is bound to occur. If the flooring material is bent or twisted 1 mm-10 mm, a step with the side flooring material will occur 1 mm-10 mm. However, if the step between the flooring material and the flooring material is 0.2-0.5 mm or more, the human skin is touched and rubbed, so that it can not be used as a flooring material. So far, it has not been possible to make inflexible flooring without grooves and bumps.

In order to solve the above problems, an object of the present invention is to provide a new flooring construction method that does not open step and gap without grooves and protrusions.

In addition, an object of the present invention is to provide a flooring that can be easily constructed using the construction method.

In order to achieve the above object, the flooring construction method according to the present invention, in the flooring construction method for constructing two or more flooring material on the base end, the base material and the bottom surface of the flooring material by using an adhesive, adjacent to each other After fixing the tape to the upper surface of both of the adjacent flooring material so that the surface and the sides of the flooring material coincide, the tape is removed after the adhesive is cured or hardened so that a step or gap does not occur between the flooring material and the flooring material. will be.

When the non-flexible floor is placed on the curved cement base and pressed with force, the floor temporarily stays on the floor, but if the pressure is lost, the elasticity of the floor falls if the adhesive does not win, causing a step. Of course, the adhesive strength of the adhesive may not fall if it is strong enough, but the adhesive for floor attachment is generally a weak adhesive strength in a gel-like liquid before curing with a curable adhesive by silicone or crosslinking. In addition, it can not be pressed until a person hardens one by one, it can also be fixed by pins, etc., but the surface damage and difficult to work individually. And it's hard to work with a huge piece of iron on each floor with a lot of pieces of flooring.

As a method for solving such a problem, the present invention is to press the adhesive tape where the partial step occurs in the contact portion between the flooring floor. In this way, the adhesive tape is attached to the upper surfaces of the flooring materials that are in contact, and the flooring materials are fixed by the adhesive force of the tape, so that the flooring materials are precisely adjusted without a step.

In addition, even when using a flexible flooring to remove the partial step due to the over or under use of the adhesive or the gap is issued can be more precise construction using the tape as described above. Flooring construction method using the tape described below can be effectively used in flexible flooring.

Hereinafter, with reference to the accompanying drawings will be described in more detail the construction method of the present invention.

Figure 2 is a cross-sectional view illustrating the construction of a non-flexible flooring material using a tape according to the present invention, Figure 2a is a cross-sectional view before attaching the tape to the top surface of the flooring material and Figure 2b is a tape removed on the top surface of the floor material of Figure 2a It is sectional drawing which shows.

In FIG. 2A, the left bottom ash 100a and the right bottom ash 100b are bonded to the base end 400 with the adhesive 300. At this time, as the surface of the base end 400 is uneven, the left flooring material 100a and the right flooring material 100b are stepped by the elasticity of the flooring material itself. In this state, as shown in FIG. 2B, the tape 200 is attached to the upper surface of the left bottom member 100a and the right bottom member 100b so that there is no step or gap. Thus, the adhesive 300 under the flooring material is flattened by being pushed to both edges by the pressing force of the tape 200 to maintain the step and gaps. Then, the adhesive 300 is cured to complete the construction of the flooring material.

3 is a cross-sectional view for explaining the force acting while the adhesive is cured in a state where the tape is adhered between the upper surfaces of the flooring materials. In FIG. 3, when a person first presses the upper surfaces of the adjacent flooring materials 100a and 100b with the primary force F to attach the tape 200, the lower surface of the flooring materials 100a and 100b receives the gel adhesive 200. Press again and the force will eventually affect the cement base 400. At this time, the adhesive surface of the tape 200 is completely adhered to the upper surface of the left bottom member 100a and the right bottom member 100b. When the first pressing force (F) of the tape disappears, both flooring material (100a, 100b) is to be returned to its original state by the restoring force by the elasticity of the flooring material, if the flatness of the bottom of the base (400) is different, the left flooring material (100a) And the restored position of the right flooring material (100b) is changed is the force that generates the step. At this time, the tape 200 attached to the upper surface of both flooring material is to fix the flooring material (100a, 100b) of both sides by the adhesive force to suppress the generation of steps. In addition, when the left flooring material 100a and the right flooring material 100b are brought into close contact with each other, frictional force is generated between both sides in contact with each other, and when a step occurs, frictional force is generated, thereby restoring the restoring force. Can be reduced. After the flooring material is restored without close contact with the step, the cement base 400 and the adhesive 300 existing in the gel state under the flooring material have a space between the cement base and the flooring material with the air bubbles 131, the wall, After being stretched and cured in other forms and the adhesive is cured, even if the tape 200 attached to the upper seam is removed, the flooring is supported by the adhesive force and the deformation is prevented from forming or stepping and opening.

Non-flexible flooring according to the present invention is preferably to increase the flexibility by making the thickness as thin as possible. When made thin and flexible, the restoring force due to the elasticity of the floor material is reduced, thereby reducing the incidence of the step difference.

FIG. 4 is a cross-sectional view showing a state in which the adhesive is completely cured, as shown in FIG. 3. In FIG. 4, the flooring materials 100a and 100b are attached to the base end 400 by an adhesive, and the flooring materials 100a and 100b are completely attached as the adhesive is completely cured and the base end 400 is bent. Removing the tape 200 in this state is to complete the flooring construction according to the present invention.

3 and 4 illustrate that the scale or the bending of each component is more curved than the actual one, and the base is less than that shown, and the thickness of the adhesive 300 may also be thin.

The flooring material which can use the construction method of the present invention without grooves and protrusions on the side will be described.

As a flooring material according to the present invention may be used as the existing wood flooring as it is, it is preferable to use a thinner thickness. Since this construction method can be installed flooring without protrusions and grooves can be installed by making the thickness of the existing wood flooring thinner about 3mm thinner. In addition, as the thickness of the wood floor is thinner, the elasticity becomes weaker and easier to bend, but it is more suitable for the present construction method. Thus, the cost of the wood material itself can be reduced and natural damage can be reduced.

In addition, as a material of the non-flexible flooring material, not only a material having a high elasticity such as wood, MDF, HDF, and artificial resin can be used, but also a fiber-based lightweight cement type of inorganic material or a fiber inside the magnesium board can be used. When using lightweight cement or magnesium board or inorganic flooring material, it is a non-combustible material that is safe in the event of fire, and it is strong in water or moisture, so there is little shrinkage expansion, no rot or mildew, and printing paper veneer and coating on the upper surface of flooring material. Edo, compared to the coating on the wood under the same conditions, there is an advantage that the stamping phenomenon is significantly less durability is improved.

In addition, as a flooring material for use in the construction method of the present invention will be described with reference to the drawings.

5 is a cross-sectional view of an embodiment in which two or more materials are adhered and used as a flooring material which can be used in the construction method of the present invention. 5, the kraft paper or nonwoven fabric 120, the printing paper or veneer 130, and the melamine sheet 140 are adhered with an adhesive on a rigid plate 110 including a magnesium board, and then compressed into a high temperature and high pressure plate. I can make it and use it. And it can be cut and used to the size that is easy to use when constructing.

6 is a cross-sectional view as another flooring material according to the present invention. As a functional board member 150 for a surface that is already molded on a rigid plate 110 including a magnesium board, the veneer layer is first formed by high temperature and high pressure, and then the surface is hardened by an adhesive 190. Can be obtained.

FIG. 7 is a cross-sectional view of another embodiment of the functional plate of FIG. 6. FIG. As shown, kraft paper or nonwoven fabric 120, printing paper or veneer 130, melamine sheet 140, and a patterned metal plate 170 are laminated in order on the press plate 910 to press 920 Pressing at high temperature and high pressure) can produce a functional plate material in which a ring of natural veneer is formed in three dimensions on the melamine resin layer 140. If such a functional plate is produced as shown in Figure 6 it can be made of a higher quality flooring material.

Floor plate according to the present invention as described above can be used to have a thickness of about 2 mm ~ 6 mm. When the bottom plate is 6 mm or more in thickness, the elasticity of the stiff material such as magnesium board increases, so that there is a high probability that a step difference occurs in construction. Therefore, the greater the thickness of the flooring, the higher the adhesion of the flooring adhesive and the tape. In particular, when the adhesive strength of the tape is increased, a problem may occur that may be more difficult when removing the tape after the bottom adhesive is completely cured.

Figure 8 is a cross-sectional view showing a state in which the construction between the floorings according to the present invention shows a flooring with chamfered corners. As shown, the flooring (100a, 100b) by cutting off the upper corners to form a chamfer 101 can not only eliminate the step that occurs finely, but also can prevent the problem of bare skin. When the corner is cut off, the functional board 150 attached to the upper part of the rigid body 110, such as magnesium board, if the thickness of the veneer layer is thin, the magnesium board layer, etc. can be seen, wherein the upper side of the magnesium board If you dye the part in wood or dark color, it can be used in aesthetic sense.

9 is a cross-sectional view as another flooring material according to the present invention. The flooring material of FIG. 9 is laminated when the plate 160 having a slight elasticity on the top or bottom of the basic rigid body 110 and is attached to the top layer again by attaching a veneer layer as the functional flooring material or the plate material 150 to walk. It has the effect of improving the feeling or reducing the noise between layers.

Usually, the floor finish consists of a surface finish or a separate surface material on the body. In particular, in order to increase the surface strength or to add a function to the surface material is a trend to change to the method of making a separate and adhesive to the body member.

Plywood or HDF artificial resin PVC used as a member of the flooring in the above description has various disadvantages. Wood materials have weaknesses such as weakness of moisture or water, severe changes in length, rot or mildew, and artificial resins have disadvantages such as length change caused by plastic odor temperature.

In order to remedy these shortcomings, there have been attempts to change the members to inorganic materials. However, simply changing the plywood of the wood-floored flooring to inorganic materials has the advantage that the characteristics of the inorganic materials are not easily burned, resistant to moisture, and the shape change by temperature is small. have. However, it is difficult to manufacture the flooring with inorganic materials. Because flooring materials are hard to make precise projections and grooves because of the hard and brittle nature of inorganic materials, the flooring material of inorganic materials is difficult to use as flooring materials in connection with construction requirements such as making grooves and protrusions and fitting them precisely. .

Inorganic plates have very little shrinkage expansion and humidity, so they do not warp themselves. However, when an organic surface material with high shrinkage expansion is adhered to one side of the inorganic material, a phenomenon such as bimetal occurs and it is bent up and down. Because of this, if the grooves and protrusions made by CNC are formed on the side of the flooring material, they will be distorted and not fit.In particular, the inorganic material is very strong and elastic, so if it is forcibly pushed in, it will be broken and broken. If you make an inorganic floor, you need to make grooves and protrusions on the side, which is about 8mm thick and even if there is a fibrous layer inside, the elasticity is very small.

In order to solve this problem, it has been commercialized that the surface material is caught on the lower surface to reduce the warping phenomenon, but it can be used only as a very expensive flooring material due to the increase of material cost and process cost.

The flooring described in Figures 5 to 9 above is a general non-flexible flooring is used as it is. However, in order to apply the construction method according to the present invention, the flooring material of the inorganic material such as a magnesium board, which is a rigid body, has little elasticity and very little warp, unlike the flooring material having a relatively soft property such as wood. Therefore, the flooring of the rigid material may be able to be used because there is some degree of bending when the thickness is thin, but there is a fear that a step may occur when the bend of the base is severe. Therefore, as a preferred flooring material of the present invention, when processing a good workability magnesium board as a flooring material of the rigid material, or if the rigid body itself is divided into pieces and adhered to the wood-based flooring material as a flooring material, as a whole the degree of warpage of the wood-based flooring material. The flooring will bend or bend overall. Therefore, if only the elastic force of the wood-based flooring material is suppressed by using a tape, it can be constructed with an adhesive like a flexible flooring material.

Fig. 10 is a perspective view showing a groove formed in a rigid flooring, and Fig. 11 is a sectional view showing a state in which a rigid body is attached to a functional plate or a flexible flooring in a fragmented state as a flooring material according to the present invention. 10 is a perspective view of the inverted state as opposed to the actual use case for the description. In FIG. 10, the rigid body 110 including the magnesium board is partially cut by a cutter or grinder to easily bend or bend. The cutting surface 111 is formed by processing, and thereby the cutting space 112 is also formed. In this way, the incision space is divided into pieces in several parts. In FIG. 10, the cutting space is not formed in all of the cross-sections of the rigid body 110, but only a portion thereof is formed. However, the cutting space may be processed so that the pieces are divided as a whole. FIG. 10 shows only the rigid part, but the machining may be performed by machining the rigid part itself and attaching it to a functional plate or the like, or may be processed in a pre-attached state. The rigid body 110 of FIG. 10 is adhesively coupled with the functional plate 150 to be split or bent based on the incision space 112 during construction to be flexibly attached along the surface of the base.

11 illustrates a state in which the rigid body 110 is attached to the functional plate 150 or the flexible flooring as a state in which pieces are divided into pieces. The flooring material is a state in which pieces 110a, 110b, 110c, and 110d are divided by the cutting space 115 in the state of being sculpted into the rigid body 110 and attached to the functional plate 150. This combination is previously attached to the entire rigid body to the functional plate 150, etc. to form the incision space 112 by machining, or in advance to make the rigid pieces (110a, 110b, 110c, 110d) to the functional state in the engraving state It may be attached to the plate member 150. Alternatively, as shown in FIG. 10, when a part of the incision space 112 is formed and impacted, the remaining part of the incision space 112 may be separated by the brittleness of the rigid body itself.

Only part of the lower rigid body of the flooring is cut or the incision space gives the flooring the flexibility to bend overall. In addition, the functional plate attached to the upper portion is bent or rolled up and forced to break or torn. The rigid body located under the flooring material also has a slight change in shape depending on the humidity temperature. As shown in FIG. 9, the two rigid bodies are attached and the rigid body is sculpted to reduce this phenomenon.

The flooring, which is sculpted from the rigid body and is totally flexible, can be easily attached to the bent base and the step can be further reduced by reducing the force to generate the step.

A rigid piece of inorganic material or the like is appropriately 5-50 mm in width and length, respectively. If the size of the inorganic material is less than 5mm, workability is expensive, and if it is larger than 50mm, it is difficult to fit when attached to the floor due to fine bending.

When the inorganic member is cut open and attached to the upper surface material, the flexibility of the entire flooring material is increased as much as the flexibility of the upper surface material, and thus the flexible material can be flexibly attached to the curved base.

Figure 12 is a cross-sectional view showing a state in which the flooring is bonded to the base material is bonded to the rigid body divided into pieces and functional plate according to the present invention bent. In the left and right flooring materials 100a and 100b, adjacent portions are brought into contact with each other by a tape 200. Rigid fragments of the bottom of the floor is cut to the portion to adhere to the functional plate 150 and the like. Therefore, the rigid body pieces according to the flexibility of the functional plate 150 and the like are naturally installed by the adhesive to the base while the interval is adjusted.

Figure 13 is a cross-sectional view showing that the adhesive penetrates into the cutting space of the rigid body portion of the flooring according to the present invention. In Fig. 13, the adhesive 300 penetrates naturally by the force pushing upwards between the incision spaces 115. In other words, when the flooring material is pressed, the adhesive applied to the cement base penetrates into the incision spaces between the rigid pieces, filling the space and curing.

When making the incision space, the incision space of the mineral material should be made close to the board, or one side of the board should be formed by the board. Inorganic materials have little warpage and are difficult to fit. However, when the incision space is formed, the fitting becomes easy due to the elasticity (bending) of the decorative plate on the upper surface. That is, in order to form an elastic incision space, a surface material top plate such as a decorative board should be made of a material sufficiently thick and elastic.

As the tape that can be used in the present invention, various tapes can be used depending on the adhesive strength and flexibility. The choice of tape can vary depending on the characteristics of the flooring to be used. For example, flexible flooring does not have strong adhesive strength and thickness is not a problem, so common tapes such as scotch tape, packing tape, or blue tape Can be used. However, the stronger the elasticity of the flooring, the stronger the adhesive strength of the tape, and the flexibility of the tape itself is also important. Because if the construction flooring material is strong and the strength to be restored is strong, when the adjacent top surfaces of both flooring materials are bonded to each other by the tape, the strength of the flooring materials to be returned to each other is increased. Therefore, the adhesive strength must be strong, and the tape itself is less warped. Strongly support both floors.

In particular, when using the flooring material to which the rigid body and the surface material of the present invention are adhered as the flooring material, it is preferable to use a tape having a stiff property without being easily bent. As such a tape, a tape having a PET-based material is preferably used having a tape having a thickness of about 50-200 μm.

In addition, the adhesive used to bond the rigid body and the surface material may be a variety of adhesives such as epoxy or silicone-based, and the adhesive suitable for the properties of the rigid body and the surface material may be used. And it would be desirable to choose an adhesive that is resistant to heat when heating.

Using the flooring construction method and flooring according to the present invention can make the thickness of the flooring thinner can be significantly improved energy efficiency when compared to flooring, such as ordinary flooring floor when installed in the floor heating place.

In addition, the construction method of the present invention is simplified to the non-flexible flooring construction to almost a deco tile construction level.

In addition, it can be directly attached to the floor, so that when the flooring made of reinforced floor material is constructed, it can greatly reduce the sound of footsteps when walking.

In addition, when the breakage occurs in the middle of the flooring, the fitting floor using grooves and protrusions must remove all the floors in one direction, but there are no fitting grooves and protrusions so that only the damaged part can be replaced, which is very easy to replace. .

In addition, as the flooring material of the present invention, when the rigid body is a magnesium board, it is resistant to moisture and water, so that there is little shrinkage expansion phenomenon, and even when used for a long time, there is no gap and no mold or rot occurs.

In addition, the use of magnesium board or fibrous lightweight cement as a rigid material as the flooring material of the present invention is 3 to 4 times higher than the wood quality when installed in the floor heating place.

In addition, as a flooring material of the present invention, only the surface material is processed separately and made, and then produced by a method of adhering the adhesive on the rigid body, the surface strength can be significantly enhanced.

In addition, the use of the construction method of the present invention can make the flooring thickness up to 2 ~ 3 mm, the application range is much wider than the general floor of 7 mm ~ 13 mm thick.

In addition, the flooring of the present invention can be cut and pasted to the bottom surface in a variety of colors and patterns to decorate the floor beautifully.

In addition, when the rigid material is used as the inorganic material as the flooring material of the present invention, when the fire occurs as a nonflammable material, the fire is not ignited and no toxic gas is generated, so it is safe.

In addition, the construction method of the present invention can be installed on the floor of any place, regardless of indoor walking outdoor or outdoor of the office or factory using a warning floor or general shoes such as a general home.

In addition, when the inorganic material such as magnesium is used as the flooring material of the present invention and the surface material is bonded to enhance the processed surface strength from the outside, the service life is greatly increased by two to three times as compared to the general floor.

In addition, the use of the flooring construction method and flooring of the present invention can reduce the thickness of the wood-based flooring to help protect the environment by reducing the consumption of wood worldwide.
