Description

Functional reinforced flooring material for architecture and constructing method

The present invention relates to a functional reinforcement flooring flooring and a construction method, and more specifically, in the construction of the reinforcement flooring, the non-woven fabric of the polyester fiber raw material is bonded to the bottom surface of the floorboard material or to the floorboard floor surface Bonding copper foil and non-woven fabric of polyester fiber raw material in the form of embossing again on the lower surface, and then using flooring to improve the thermal conductivity during heating in winter, and also for the assembly of apartment buildings The present invention relates to a functional reinforced floor covering and a method of constructing the same to reduce noise between floors, protect floorboards, and simplify construction, as well as increase electromagnetic and water wave blocking effects by copper foil and further increase thermal conductivity.

Floors generally used as flooring are classified into solid wood floor, plywood floor, and reinforced floor. Among them, the reinforced floor is a solid wood on the HDF (High density fiberboard) surface, which is compressed at high pressure by mixing finely ground wood with waterproof resin. It is made by attaching a printed film and then impregnating melamine resin with high temperature and high pressure.The reinforced floor is capable of producing various colors, has good wear resistance and durability, almost no damage to the surface, and is inexpensive and toxic during construction. The market share was very high in that no adhesive was used.

Looking at the order of constructing such a reinforced floor, as shown in Figure 7, first to arrange the irregularities so that the cement floor 100 is flat and to block the moisture and toxicity coming from the cement floor thereon polyethylene vinyl The paper (200) is laid to prevent direct contact between moisture and the floor.

Subsequently, PE foam (300: foam cushioning agent) is laid on the vinyl paper and the floorboard 400 is male and female, that is, grooves and protrusions, to compensate for the irregularities of the curved bottom and to evenly cushion the bottom of the hard floor. Install by clicking method to assemble accordingly.

However, the reinforced floor constructed by the conventional method can be used stably with high surface strength, while the thermal efficiency of the cement floor is blocked by the PE foam (also called vinyl foam) disposed under the floorboard material. There was a problem of lowering by 30%.

In other words, reinforced floors were originally introduced in Europe, where steam heating of circulation air-conditioning type was used, and in the European homes of the intimate culture where people wear shoes indoors, PE foam is suitable for use because the shock-absorbing function is sufficient. Since the thermal conductivity from the floor to the floorboard is inferior, there is a problem in the heating in winter, which is not suitable for the ondol residential culture in Korea.

In addition, there is a limit in achieving perfect smoothness when finishing with mechanical plaster in the process of conventional reinforcement flooring, which results in minute irregularities of about 1 to 2 mm, and in the case of remodeling, the degree of irregularities due to adhesive traces, etc. As a result, an air layer (A) is formed between the upper surface of the cement floor and the PE foam located on the bottom surface of the floorboard, so that even if a slight impact is applied to the top surface of the floorboard, vibration (vibration) occurs. Apartment houses such as apartments have also become a major cause of floor noise.

In addition, the conventional reinforced flooring not only reduces the sound absorption of the vinyl foam installed between the cement floor and the floorboard, but also has a shock-absorbing effect at the beginning. However, when the floor surface is uneven due to the deterioration of cushioning force due to long-term use. The click parts of the floorboards connected to each other are damaged and cause defects.In addition, these vinyl foams are not breathable and have difficulty in not only smelling but also causing harmful components to the human body when continuously applying high temperatures. .

Accordingly, in recent years, large construction companies and housing corporations have tended to exclude the use of vinyl foams such as PE foams in reinforced floors during the flooring construction process.

The present invention is to solve the above problems, while improving the efficiency of the thermal reinforcement by improving the disadvantages of the existing reinforced floor while maintaining the unique characteristics of the reinforced floor with high surface strength, and also eliminates the phenomena caused by the air layer interlayer noise The purpose of the present invention is to provide a functional reinforced flooring material that reduces the damage to the floorboard, prevents damage to the floorboard material by long-term use, shortens the working time by simplifying construction, and blocks human and electromagnetic waves.

In order to achieve the above object, the present invention, in the process of constructing the reinforced floor, the polyester nonwoven fabric mainly used for the water purifier filter is integrally bonded to the bottom surface of the floorboard material or the copper foil is bonded to the bottom surface of the floorboard material It is characterized in that the polyester non-woven fabric on the surface combined with a lattice pattern embossing and laminated on a plastic sheet laid on the cement floor surface.
At this time, it is preferable that the concave portion of the embossed polyester nonwoven fabric is 1.0 to 2.5 mm thick, and the convex portion is 3.0 to 4.5 mm thick.

And when combining only the polyester nonwoven fabric may be attached to the lower surface of the vinyl foam formed with a perforated at regular intervals.

In addition, the polyester non-woven fabric is characterized in that any one of the charcoal powder or ocher powder impregnated.

In addition, the construction method according to the present invention, the copper foil is bonded to the lower surface of the plurality of floorboards, and the bottom surface of the polyester nonwoven fabric by compression processing with a grid pattern embossing and then bonded to the lower surface of the copper foil, the copper foil and The floorboard material in which the polyester nonwoven fabric is bonded is laid one by one in such a state that the embossed portion of the polyester nonwoven fabric is in contact with the cement floor on which the vinyl paper is laid.

According to the functional reinforced floor flooring of the present invention, it is excellent in durability and impact resistance, which is inherent in the reinforced floor, can be used stably without damaging the surface of the floor, and heating heat is blocked by vinyl foam installed for shock-absorbing during winter heating. Therefore, by improving the structure of the reinforced floor to prevent a significant drop in thermal efficiency, the overall thermal efficiency is improved by more than 30 to 40%, which can be effectively applied to the residential method of Korea with an ondol culture. It can solve the noise problem between floors of apartment buildings such as apartments, villas, officetels and multi-family houses, and create a pleasant living space by blocking the harmfulness of residential spaces.

In addition, the plastic foam is deformed due to continuous pressure after reinforcement floor construction, which prevents reinforcement floors from the conventional structure, and protects the click parts of the floorboards connected to each other, and also maintains the impact relief function for a long time. As the installation process can be omitted, the construction can be simplified and the work time can be greatly reduced.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the configuration of the functional floor flooring according to the present invention.

Referring to the drawings, the functional reinforcement flooring flooring (F) according to the present invention in the known reinforcement floor, it is composed of a plurality of floorboards with grooves and protrusions formed on the side and a polyester nonwoven fabric bonded to the floorboard bottom surface Or a polyester nonwoven fabric processed by embossing attached to the floorboard material, the copper foil attached to the bottom surface of the floorboard material and the lower surface thereof, and laminated on a vinyl paper laid on the cement floor surface. will be.

This will be described in detail below.

First, the floorboard material 10 used in the present invention may be a well-known one, and may form various colors and patterns on the surface, and grooves (groove: 11) and the side surfaces of the floorboard material 10 are in contact with each other. The protrusions 12 are alternately formed so that a plurality of floorboards can be continuously joined in the longitudinal and transverse directions by click coupling.

In addition, as shown in Figure 1, the polyester nonwoven fabric 30, which can be said to be a characteristic component of the present invention, is adhesively bonded to the lower surface of the floorboard material, that is, the polyester nonwoven fabric is light and not easily torn Fine weave fabric is densely woven and excellent in breathability, thermal conductivity and thermal insulation, good pressure resistance and restoring force, these polyester non-woven fabrics are subjected to compression processing and transferred heat to the bottom surface of the floorboard using an aqueous adhesive Add to bond.

Accordingly, a very thin adhesive layer 31 is formed between the floorboard material and the polyester nonwoven fabric.

In addition, the copper foil 20 is attached to the bottom surface of the floorboard prior to bonding the polyester nonwoven fabric, and the polyester nonwoven fabric is compressed by lattice embossing as shown in FIG. 2 and then the copper foil is attached using an aqueous adhesive agent. It may be bonded to the bottom surface of the floorboard.

At this time, the copper foil 20 is coupled to the bottom surface of the floorboard material peeling the copper plate to a thickness of 0.5 ~ 1㎜, thereby improving the thermal conductivity and has a harmful electromagnetic wave blocking and water wave blocking effect in the living space.

In addition, when the polyester nonwoven fabric 30 is too thin during compression processing, there is a possibility that the shock absorber may not be absorbed between the floorboard material and the cement floor surface, whereas when too thick, the cushioning property is too large and the floor is formed by load. May be damaged, so 1.0 to 3.0 mm, preferably 2.5 mm thick.

In addition, when the polyester nonwoven fabric is used by embossing the lattice pattern at intervals of 15 mm, the concave portion is processed to 1.0 to 2.5 mm thickness and the convex portion is processed to 3.0 to 4.5 mm thickness to cover the unevenness of the cement floor to 2 mm. Therefore, the floorboard material is in close contact with the cement floor to remove the air layer to block the noise caused by the ringing effect, to maximize the sound absorption and to filter the dust on the cement floor.

That is, Figure 3 shows a state of bonding the embossed polyester nonwoven fabric on the vinyl paper laid on the cement floor surface, in the drawing shows a state in which only a portion of the embossed portion of the polyester nonwoven fabric is pressed, in actual construction As shown in Figure 4, the convex cushion portion of the embossed polyester nonwoven fabric 30a has a height formed on the bottom surface, and the air layer is removed as it is pressed in the direction of the arrow to block the ringing phenomenon. Will be.

Such polyester non-woven fabric (30, 30a) may be used by impregnating the processing of fine charcoal or loess into fine powder, thereby having a deodorizing and antibacterial function, and can also be obtained with far-infrared and anion generating effects.

The vinyl paper 50 may be polyethylene vinyl or the like as it is known to block moisture on the cement floor surface before constructing the floorboard material.

Referring to the example of using the functional reinforced floor flooring of the present invention having the configuration as described above are as follows.

In order to perform floor construction in an interior space such as a general private house or apartment or officetel, the floor reinforcement flooring (F) according to the present invention is installed, and the bottom surface (cement floor surface) of each floorboard material 10 before construction is performed. On the facing side) to prepare a reinforced flooring material that is bonded to the polyester non-woven fabric (30) pressed to a thickness of 2.5mm with an aqueous adhesive such as a natural adhesive.

At this time, the copper foil 20 is attached to the lower surface of the floorboard material 10, and the polyester nonwoven fabric 30a may be a compressive process by embossing a lattice pattern.

Subsequently, the cement floor 60 is evenly and flattened using an apparatus such as a grinder, and a finishing material (not shown) is fixed to the bottom edge to prevent moisture from rising from the cement floor. Spread polyethylene vinyl paper 50 on the wide.

Next, the floorboard material 10, which is combined with the polyester nonwoven fabric 30, is laid one by one from one end of the room, and the grooves 11 and protrusions formed on the floorboard material 10 and the floorboard material newly laid on the floor, respectively. (12) in close contact with each other at an angle of about 30 to 40 degrees and then move the floorboard material up and down little by little to put the grooves and projections, and then put it on the floor and hit it with a rubber hammer, etc. Combine.

Then, after laying all the floorboards 10 on the indoor floor, a floorboard (not shown) is installed between the floor and the wall to finish.

When the heating is completed after the construction of the reinforced floor flooring material (F) according to the present invention as described above, the heat conduction from the cement floor surface is good and the heat of heating is maintained for a long time, and the sound absorption effect is excellent, the interlayer noise of the assembly building such as an apartment As the occurrence is significantly lowered, even if an object falls on the flooring material (F) or little children jump, it rarely causes damage such as a ringing phenomenon on the lower floor. It has no filtration effect of cement components and makes an environment-friendly and pleasant living environment.

Furthermore, when the copper foil and embossed polyester nonwoven fabric are attached to the bottom surface of the floor board, the air layer between the cement floor and the floor board is removed to remove the ringing phenomenon, as well as to block electromagnetic waves and water waves in the space. It will be further improved.

In addition, even when such a flooring is used for a long time, there is almost no deformation for pressing and it is easy to use because it maintains continuous elasticity.

5 and 6 show the configuration of a functional reinforced floor flooring according to another embodiment of the present invention. Here, the same reference numerals as in Fig. 1 denote the same members having the same function.

According to the present embodiment, after attaching the polyester nonwoven fabric 30 to the bottom surface of the floorboard material 10, the vinyl foam 40 is further attached to the bottom surface, wherein the vinyl foam is perforated at regular intervals 41 It is preferable to use through).

This is formed on the vinyl foam 40 in a process in which heat is transferred from the cement floor surface 60 by heating in a state where the floorboard material 10, the polyester nonwoven fabric 30, and the vinyl foam 40 are sequentially stacked. In order to maintain the heat conduction well through a plurality of perforations 41 and to maintain the shock absorbing power of the vinyl foam as it is.

Since the effect of the functional reinforced floor flooring according to this embodiment is the same as the above-described embodiment will be omitted.

However, according to the flooring of the present embodiment, as well as the heat conduction and sound absorption effect, it also serves as a shock absorbing function.
