The present invention relates to a plate-like material for forming a floating floor structure effective in noise, vibration, and heat insulation in a building floor.

As a plate material for forming the floating floor structure, 15-25 mm waterproof plywood has been generally used. However, even after the use of waterproof plywood over 10 years, due to the moisture coming from the bottom of the slab consisting of cement, the plywood is often rot, weak durability is not suitable for the floor structure. Cement takes about 10 years to fully cure, and because it contains moisture depending on the season even after curing, it continuously supplies moisture to the waterproof plywood and eventually becomes waterproof due to the closed space structure where moisture is hard to escape. It is a factor that weakens the durability of plywood.

In general, the process of making a waterproof plywood is a stain-oil type of waterproofing and preservatives are applied to the plywood, and to make a waterproof plywood is a chemical treatment process to prevent the wood from deteriorating due to mold and moisture. Waterproof plywood is usually water-resistant preservatives (CCA) in a proportion of the water in the plywood is put under pressure to apply the appropriate pressure to the chemical into the wood (CCA Pressure Treated Lumber method).

In another object of the present invention, the thicker the thickness of the existing waterproof plywood is effective to reduce the impact or vibration coming from the top, but the disadvantage is that the price is expensive. Therefore, the price is inexpensive, and the noise from the top is to be attenuated.

In recent years, according to the regulation of interlayer noise of the bridge, a floor having a floating floor structure with relatively low noise and vibration has been spotlighted.

In addition, the Ministry of Construction and Transportation and the Ministry of Commerce, Industry and Energy have introduced the “Energy Efficiency Rating Labeling System” for apartments and other buildings, inducing the efficient use of energy by attaching up to five star-shaped labels for each grade. The choice of material is a very important issue.

The present invention was created to solve such a problem, using honeycomb and urethane to make a plate material that is strong against impact and noise from the top, and is light, excellent in insulation performance, and does not rot even after using for more than 50 years. .

Hereinafter, described with reference to the accompanying drawings the present invention.

1 is an exploded assembly perspective view of a plate-like material with a built-in honeycomb for the floating floor structure of the present invention.

On the lower portion, the outer frame 140 corresponding to the slope of the lower plywood 150 is attached onto the lower plywood 150 forming the support plate by using an adhesive.

Figure 2 is an exploded perspective view showing the assembled structure of the plate-like material with a built-in honeycomb structure for the present inventors.

The interior of the space consisting of the lower plywood 150 and the outer frame 140 is attached to increase the honeycomb 130 by the height of the outer frame 140. At this time, the method of attaching the honeycomb 130 is a method of applying a general adhesive and a method of attaching using a two-component urethane to form a foam.

The method of attaching with an adhesive is a general method. After applying sufficient adhesive to the bottom and top surfaces of the honeycomb 130, the honeycomb is fixed with tacapin at the corners to fix the honeycomb.

Then, the upper plywood 120 is attached to the honeycomb upper surface and the outer frame 140, and then pressed by pressing for about 12 hours to 2 days.

In another method, a thin urethane foam is applied to the upper surface of the lower plywood 150 and the lower surface of the upper plywood 120. After applying the curing agent to the top and bottom of the honeycomb spread the honeycomb 130 in the frame consisting of the lower plywood 150 and the outer frame 140 and fixed using a takapin at the corners so that the honeycomb is fixed, the top The plywood 120 is attached to the honeycomb upper surface and the outer frame 140, and then pressed by pressing for about 2 to 30 minutes. At this time, in consideration of the working speed to select the appropriate curing time product.

In this case, the foamed urethane molding is formed inside the honeycomb 130, and it becomes harder.

3 is an exploded perspective view of a plate-like material in which a uretan foam molding is formed in a floating floor structure for an embodiment of the present invention.

Attach the outer frame 140 corresponding to the slope of the lower plywood 150 using an adhesive on the lower plywood 150 to form a support plate on the lower portion, and the support 141 in the interior between the outer frame 140 A number of arrangements are made to prevent sag from the top, and the upper plywood 120 is attached on the top of the outer frame 140.

The plate-shaped material thus prepared is seated in the steel frame formed so that urethane does not leak, and the urethane is injected through the urethane inlet 145 on one side of the outer frame 140 to foam.

Meanwhile, the lower plywood 150 and the upper plywood 120 form a waterproof film 110 on the surface thereof. That is, after forming the waterproof film 110 on one side of the wide surface of the plywood, the plate-shaped material in which the honeycomb 130 for floating floor structure according to the present invention is built may be distinguished and attached only at the top and bottom. As a method of forming the waterproof film 110, there is a method of urethane coating, PET thin film plywood, Tepro coating, thin film Teflon sheet attached, Teflon vacuum deposition.

Urethane coating is a method of distributing urethane on the surface of plywood and applying a curing agent on it to treat the coating with urethane, which has very excellent physical properties such as abrasion resistance, chemical resistance, tear strength and tensile strength elongation.

Teflon coating refers to a Teflon-coated plywood dried by heat treatment after applying a primer to the surface, followed by spray application of Teflon. Teflon coated plywood has special features such as good chemical inertness, heat resistance, non-tackiness, good electrical insulation and low coefficient of friction.

PET thin film plywood refers to a film obtained by transferring a polyester (PET) into a thin film on the plywood.

In this way, the waterproof film is made of plywood treated. In the present invention, for convenience, the upper plywood 120, the lower plywood 150, but divided into the same components.

4 to 5 is a view showing a preferred state of use of the plate-like material for the floor structure according to the present invention,

Mounting the plate material for the floor structure of the present invention on the crutches 200 that can be adjusted horizontally on the slab 400 and the crutches 200 mounted on the crutches 300, and fixed with takapin from the top do.

The effects of the present invention configured as described above are as follows. In general, compared with the plywood forming the floating floor structure, it is high in tensile strength and compressive strength, light, strong, and effective for insulation. In particular, it has a significant reduction in interlayer noise and vibration compared to conventional materials. Compared to the general plywood, the honeycomb 130 has the same effect as the plate by the numerous air layers therein, and the urethane reduces the interlayer noise by the porous layer and the soft foaming property therein. The urethane-foamed plate-like material of the present invention exhibits an excellent effect in thermal insulation of buildings.

The revised Ordinance of the Regulations on Building Equipment Standards, etc., which was implemented from June 1, 2001, lowers the standard of heat transfer rate of building parts by region (Attachment 4 of the notice from the Ministry of Construction and Transportation) and consequently strengthens the insulation standard of buildings by more than 20%. As a result, the use of high thermal conductivity insulation material causes the wall thickness to become relatively thick.As a result of the new amendment and the Ministry of Construction and Transportation, the rigid foamed polyurethane foam is designated as the lowest thermal conductivity of the “A” grade in the regulations. In addition, when the thickness is determined in consideration of heat transfer resistance, since it is about half the thickness of the foamed styrene foam, it can be advantageous to secure indoor and outdoor spaces and the cross section of the building.
