CONSTITUTION:The thickness of a precious wooden veneer 1 is set to 2-6mm, and a transparent painted layer for forming a colored layer or improving abrasion resistance is formed on the surface, and a vinyl chloride sheet 2 mixed with powdered lead or rubber foamed sheet 2 is attached as a sound insulating, vibration damping, or cushioning sheet 2. Further, the coniferous wooden members 3 having small width are attached in parallel, keeping a slight gap 4, so as to be perpendicular to the fiber direction of the precious wooden veneer 1. A cushioning member 6 is attached in single form or independent-foamed type dampproof sheets 5 and the cushioning members 6 such as synthetic resin foamed body are attached in succession on the reverse surface of the coniferous wooden member 3 having a small width. Accordingly, the wooden floor member having the superior sound insulation property and free from warp can be obtained by using the coniferous wooden material.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a sound-insulating wooden flooring material suitable for being applied directly to a concrete flooring material.

[Prior Art] In the past, many mid-to-high-rise houses had carpets attached directly to the concrete floor using felt. However, carpets tend to get dirty easily, and the occurrence of dust mites has become a problem.

Therefore, instead of pasting carpets, we pasted a 0.3 to 1 mm thick precious wood veneer on the surface of lauan plywood, and then pasted a foamed resin sheet about 2+ nm thick on the back side of the decorative plywood, which was made from natural precious wood veneer. Nowadays, floors are constructed by attaching wood-based flooring materials directly to concrete floors, but this has the disadvantage that wood-based flooring materials have inferior sound insulation properties compared to carpets, which impairs livability.

Furthermore, recently, the depletion of wood resources in tropical rainforests has become a problem from the viewpoint of nature conservation, and it has become difficult to obtain lauan wood, the main raw material for plywood. Therefore, there is a movement to use side-leaved trees, which are easy to plant, as a substitute for lauan wood.

Furthermore, in the market, there was a demand for a decorative board with a high-class feel that uses a thick veneer of precious wood instead of a veneer of precious wood with a thickness of 03 to 1).

However, simply using a thick veneer of precious wood and attaching side-leaf plywood to the back side has the disadvantage that it is very likely to warp.

Furthermore, when loose coniferous wood is used instead of coniferous plywood, there is a drawback that warping is more likely to occur.

[Problems to be solved by the invention] The unidentified person solves the drawbacks mentioned above, has excellent sound insulation,
Moreover, this invention was completed as a result of daily research aimed at providing a wood flooring material that does not warp and is made of coniferous wood.

[Means to solve the problem] This invention is applied to the back side of a medium board made of precious wood with a J size of 2 to 6 mm.

A sheet with sound insulation, vibration damping, or cushioning properties is pasted, and on the back side, small pieces of softwood are pasted with a slight gap so that the #l1m direction is perpendicular to the fiber direction of the precious wood veneer. and a sound-insulating wooden flooring material that is characterized by a cushioning material alone or a moisture-proof sheet and a cushioning material adhered to the back side, and a sound-insulating wooden flooring material that has a sound-insulating material on the back side of a precious wood veneer with a thickness of 2 to 6 mm. A sheet with vibration damping or cushioning properties is pasted, and on the back side, small pieces of Ryu leaf wood are pasted side by side with a slight gap so that the fiber direction is perpendicular to the fiber direction of the precious wood veneer. A plurality of elongated decorative boards are formed, and a plurality of these elongated decorative boards are arranged in the width direction while being shifted little by little in the length direction so as to form a step-like shape, and the joints are connected so that they can be bent freely. This invention relates to a sound-insulating wooden flooring material characterized by having a cushioning material alone or a moisture-proof sheet and a cushioning material sequentially attached to the back surface thereof.

This invention will be explained in detail below based on the drawings.

FIG. 1 is a side view showing one embodiment of the present invention, and the thickness is 2 to 2.
Sound insulation properties on the back side of the relatively thick 6mm precious wood veneer l.
A sheet 2 having vibration damping or cushioning properties is attached.

The thickness of the precious wood veneer 1 is set to 2~Eimm because the thickness is 2.
If it is less than mm, it is likely to warp when used as a flooring material, and it will not have a commercial quality feel; be. In addition, a transparent paint layer mixed with α-alumina or silicon carbide may be formed on the surface of the precious wood intermediate plate 1 to form a colored layer or to improve wear resistance.

As a sound insulation or vibration damping sheet, powder shipman PVC sheet,
Examples include inorganic powder-filled rubber sheets, vinyl chloride sheets, etc., and those with a thickness of 0.8 to 2 mm are preferred.

Further, the cushioning sheet may be a foamed sheet of natural rubber or synthetic rubber, or a sheet with cushioning properties such as olefin foamed sheet +-, S, and preferably has a thickness of 1 to 2 mm.

Next, on the back side of the sheet, narrow side confectionery materials 3 are pasted side by side with a slight gap 4 so as to be perpendicular to the m-fiber direction of the precious wood veneer l.

The narrow 31-leaf wood 3 has a thickness of 4 to 6 mm and a width of 20 to 5 mm.
0) is preferred, but is not limited to this. t
The type of single-leaf wood 3 may be pine, cedar, toga, or the like. The gap 4 between the softwood materials 3 is generally 2 mm or more, and may be in contact with each other.

The cushioning material 6 alone or the moisture-proof sheet 5 and the cushioning material 6 are adhered to the surface of the small-width softwood material 3 described in 1-.

As the moisture-proof sheet 5, an independent foam type sheet such as a foamed polyethylene sheet, a foamed polyurethane sheet, or a foamed synthetic rubber sheet is suitable, and the thickness thereof is preferably 1 to 3 mm. The moisture-proof sheet 5 is required when the cushioning material 6 does not have moisture-proof properties, and is not necessarily required when it has moisture-proof properties.

The cushioning material 6 may be made of various synthetic resin foams, polyester fibers, polypropylene fibers, nylon fibers, or other fibers made into a mat shape by, for example, a needle punch method.

In addition, as shown in FIG. 1, unevenness 9 is formed on the matted material, and natural rubber is applied to the front, back, or both sides.
Apply liquid materials such as methyl methacrylate rubber, styrene-butadiene rubber (SBR) '3 synthetic rubber, and other synthetic resins with adhesive properties to the pine I. It is preferable to have good elasticity and to prevent the unevenness from disappearing easily, in other words, to prevent the elasticity from disappearing during use. In order to maintain this elasticity, it is preferable that the liquid material applied has elasticity when cured or dried. In addition, the bipedal mat may be composed of one type of fiber, but it may be composed of two types of similar fibers (for example, 80% polyester fiber and 20% polypropylene fiber).
It may be configured using a mixture of . In addition, the degree of nasoness is 2 to 6.
mm is preferable, but it is not something that can be determined visually.

Further, the total thickness of the cushioning material alone or the moisture-proof sheet 5 and the cushioning material 6 is preferably 4 to 10 mm, but is not limited thereto. If the J groove is too thin, the γ1 blocking effect will be poor, and if it is too thick, it will not only cause economic problems, but also cause the floorboards to be too thick when renovating a house, making them higher than the thresholds and cracks. Construction may become impossible, or
When walking on the I- of the floorboard, the floorboard sinks significantly, resulting in a disadvantage that the feeling of walking becomes worse.

On the four sides of the decorative board manufactured in this way, 11 [seeds 7 and female seeds 8] are formed. Instead of male and female seeds, other holding means such as a joint process may be formed.

Fig. 2 is a hemostasis diagram of a wide decorative laminate manufactured by connecting the elongated decorative laminates of Fig. 1, and Fig. 3 is a sectional view taken along line A-A in Fig. 2.
A wide decorative board is constructed by arranging a plurality of elongated decorative boards in the width direction so that they are slightly shifted in the length direction so as to form a step-like shape. At this time, the male fruit 7 and the female fruit 8 formed on the side surfaces of the slender decorative board are loosely fitted together, and the fitting portion is filled with flexible hot melt resin 10 from the back side to form the slender decorative board. The decorative boards are configured to be flexible when they are joined together. Incidentally, when joining the elongated decorative laminates, the force exerted by the small gaps 4 between the narrow coniferous wood materials in the shape of a wedge between the adjacent elongated decorative laminates is very strong in terms of strength. Examples of flexible hot melt resins include ethylene vinyl acetate resins, urethane resins, and polyester resins.

On the back side of the wide fat plate thus formed, a cushioning material 6 alone or a moisture-proof sheet 5 and a cushioning material 6 having the same shape as the pad is attached. Of course, the moisture-proof sheet 5 and the cushioning material 6 may be divided into one or three parts and stuck together.

The wide sound-insulating wood flooring formed by joining the elongated decorative boards in this manner has better sound insulation than the sound-insulating wood flooring with large sheets. This is thought to be because it becomes difficult for sound to propagate in the divided parts.

[Effect of the invention] As described above, this invention has sound insulation properties and
A sheet with damping or cushioning properties is attached, and a small piece of coniferous wood is attached to the back of the sheet instead of lauan plywood, so there is almost no problem of natural destruction of the rainforest, and the surface The name wood veneer must be a relatively thick veneer with a thickness of 2 to 6 mm, and the back side of the name wood veneer should be covered with a sheet that has sound insulation, vibration damping, or buffering properties, and the fiber direction or fa of the name wood veneer should be Coupled with the fact that the narrow coniferous wood materials are adhered side by side with 1-1-2 gaps in the direction perpendicular to the fiber direction, there is a great advantage that the decorative board does not warp.

In addition, is there a barrier between the precious wood veneer and the narrow coniferous material? “F-sexuality,
A sheet with vibration damping or cushioning properties of 4j is interposed, and
Since the wt impact sealing material 6 is attached to the back side of the narrow softwood material, it has excellent sound insulation properties and passes L-50 at the floor impact sound (light impact) level.

In addition, we have created a thin decorative board made by sequentially pasting precious wood veneer, Sea I wood, which has sound insulation, vibration damping, or cushioning properties, and small width open timbers, gradually increasing the length in a step-like manner. By arranging multiple sheets in the width direction while shifting them in the same direction, connecting them so that they can be bent freely, and attaching a cushioning material to the back side to form a sound-insulating wood-based flooring material, it is easy to install. In addition, the joining line in one direction (left and right direction in Figure 3) of the sound insulating wood flooring material does not line up in a straight line, making it possible to provide sound insulating wood flooring material with excellent design. It is something.

[Example 1] A foamed synthetic rubber sheet with a thickness of 1 mm is attached to the back side of an oak ribbon board with a size of 30 cm x 90 cm and a thickness of 4 mm, and a 1 mm of foamed synthetic rubber sheet is attached to the surface of the oak veneer in a direction perpendicular to the force direction of the oak veneer. As shown in the figure, narrow girder materials with a thickness of 5 mm and a width of 30 mm are pasted side by side with a gap of about 1 mm, and a foamed polyurethane cushioning material with a thickness of 5 mm is pasted on the surface to form the desired floor. manufactured the material.

[Example 2] Foamed synthetic Yomshi-1 with a tV of 1rnrn was placed on the surface of an oak bending board with a size of 30cm x 90cm and a thickness of 4mm.
Next, on the back side, line up small beams with a thickness of 5 mm + and a width of 30 mm with a gap of about 1 mm 2 in the direction perpendicular to the fiber direction of the oak veneer. In addition, on the back side, we used a foamed polyethylene sheet with a thickness of 2 mm, and polyester fibers were intertwined with the polyester base fabric using a needle punch method, and the back side was processed to have a convex pattern with a convex pattern. The desired flooring material was manufactured by sequentially pasting the cushioning materials (including the following).

[Example 3] After the oak suspension plate, foamed synthetic rubber sheet, and narrow beam material used in Example 1 were attached in sequence.

Cut this to a thickness of 10mm, a width of 80mm, and a length of 90mm.
0 mm long thin decorative board is manufactured, and 5 pieces of this are rolled in the longitudinal direction.
The planar shape was shifted by 0 mm so that the planar shape became step-like, and they were joined using male and female grooves. The male and female grooves are loosely joined to form a slight bend at the joint so that they can easily conform to the unevenness of the base, and there is also a hot glue that has some flexibility after curing in the groove on the back of the joint. They were joined by injecting melt resin. Then, a foamed polyurethane acid cushioning material having a thickness of 7 mm was adhered to the entire back surface of the material to produce a desired flooring material.

[Example 4] The cushioning material used in Example 3 was made by intertwining polyester fibers with a 2 mm thick foamed synthetic polyethylene sheet and a polyester base cloth using a needle punching method, and creating an uneven pattern on the back side so that the convex part had a concave-convex pattern. A desired flooring material was manufactured in the same manner as in Example 3, except that a processed cushioning material having a thickness of 5 mm (including the height of the convex portion) was used.

[Example 5] A foamed synthetic rubber sheet with a thickness of 1 mm is attached to the back side of an oak wood board with a size of 30 cm x 90 cm and a thickness of 3 mm, and a foamed synthetic rubber sheet with a thickness of 1 mm is attached to the back side in a direction perpendicular to the fiber direction of the oak veneer. As shown, small pieces of pine wood with a thickness of 5 mm and a width of 3 m are pasted side by side with a gap of 0.5 mm, and on the back side, a foamed polyethylene sheet with a thickness of 2 ffiffl, and a polyester base fabric with a polyester base fabric. The fibers are entwined using a needle punch method, and the back side is textured to create a pattern of protrusions.The thickness is 5 mm (including the height of the protrusions).
The desired flooring material was manufactured by sequentially pasting the cushioning materials.
