Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a floor finishing method in which a flooring material is directly applied to a concrete slab or the like of an apartment complex, a store, etc.

[Conventional technology]

Conventionally, it has been known to apply wood-based flooring directly to the subfloor surface of a concrete slab or the like, but single-layer wood-based flooring has a major drawback in that it has poor floor impact sound insulation properties. Therefore, a multilayer flooring system was developed in which a wood-based finishing material was used as the surface material and cushioning material, plywood, etc. were layered underneath.

[Problem to be solved]

When multiple layers of flooring are pasted one by one onto the subfloor, each single layer of flooring can easily warp or become distorted, so each layer has to be made smaller in size. . It is difficult to install a large number of small-sized flooring materials to be pasted on the subfloor, and the flooring also has the disadvantage that it becomes uneven along the unevenness of the subfloor. In addition, since it is easily distorted, there are limits to the combinations of materials that can be used, and there are also limits to the sound insulation performance.

Furthermore, since it is easy to warp, it has poor adhesion to the subfloor, and as a result, it is affected by moisture from the subfloor, and there is a risk that it may become distorted. Furthermore, if you try to nail it down to prevent it from going awry, there is a risk that the floor will sink and create dents on the surface, or that the adhesion will fail and the sound insulation performance will deteriorate.

Therefore, it is an object of the present invention to provide a floor finishing method that is easy to construct and has few irregularities, and can also construct a floor that is excellent in blocking performance of lightweight floor impact noise.

[Means for solving problems]

In order to achieve the above object, the first invention provides a surface finishing material made of a relatively hard material such as wood or synthetic resin, or a surface finishing material with a first buffer layer formed on the back surface thereof. A panel with a supporting plate such as veneer plywood sandwiched between the first buffer layer and the second buffer layer, or the supporting plate and the second one! The structure consisting of a shock layer is used as the lower panel, and the second buffer layer of a large number of lower panels is grounded and spread on the subfloor, and then the upper panel is attached to the lower panel so as to cover the butt points between the lower panels. This is what I did.

In the second invention, a first buffer layer is formed on the back surface of a surface finishing material made of a relatively hard material such as wood or synthetic resin, and a backing board such as plywood or the like is further formed on the back surface of the first buffer layer. A second buffer layer is formed on the back side of a support plate such as plywood as the upper panel, and a large number of lower panels are laid down on the subfloor, and then the butt points of the lower panels are The upper panel is attached to the lower panel so as to cover it.

[Effect]

In this invention, since the upper panel and the lower panel are separated, each panel alone is less likely to warp or become distorted, so a large size can be used. The use of large-sized upper and lower panels makes construction easier, and after the lower panels are laid on the subfloor, the upper panels are attached to cover the butt points between the lower panels, resulting in a floor with less distortion. Moreover, the floor impact sound isolation performance has also been improved.

〔Example〕

In the embodiment shown in FIG. 1, a surface finishing material 1 is formed from a relatively hard material such as wood or synthetic resin, and a first buffer layer 2 is formed on the back surface of this surface finishing material 1. It was set as panel 10. Further, a lower panel 20 was formed by forming a second buffer layer 4 on the back surface of a support plate 3 made of plywood or the like. Note that the upper panel 10 is composed of only the surface finishing material 1,
The lower panel 20 may include a first buffer layer 2, a support plate 3, and a second buffer layer 4. The second buffer layer 4 of the lower panel 20 is directly attached to the floor base 5 such as a concrete slab, and then the upper panel 10 is attached to the support plate 3 of the lower panel 20 so as to cover the butt portions of the lower panels 20. go. The thickness of the surface finishing material 1 is 6 mm or less, preferably about 1 to 5 mm, and the thickness of the first buffer layer 2 is 1 to 4 mm.
About 1 tributary amount is suitable. And this first buffer layer 2
25kg/(to) for local load 100CI11
・It is desirable to have a static spring constant of less than ci. The first and second buffer layers 2.4 are preferably made of elastic foam or fibrous material, porous fiberboard, rubber-like elastic material, or the like. It is not necessary to use the same material for the first buffer layer 2 and the second buffer layer 4, and different materials may be used for each layer.

The example shown in FIG. 2 shows an example in which the upper panel 10 is pasted so that its longitudinal direction is perpendicular to the axis of the butting point of the lower panel 20, and FIG. 3 is the same as FIG. 2. However, the lower panel 20 is enlarged, and the example shown in FIG. 4 shows an example in which the axis of the abutting portion of the lower panel 20 and the longitudinal direction of the upper panel 10 are parallel to each other. Furthermore, FIG. 5 is a cross-sectional view of the completed floor by laminating the lower panel 20 and the upper panel 10 on the floor base 5. At this time, the lower panel 20 may be provided with a slight gap between the butt points. be.

The example shown in FIGS. 6 and 7 shows an example in which the second buffer layer 4 constituting the lower panel 20 is formed in the shape of a square lumber at least on the periphery of the back surface of the support plate 3, and the construction method is described above. It is the same as the one above.

The embodiment shown in FIG. 8 shows a structure in which the support plate 3 and the second buffer N4 constituting the lower panel 20 are divided into multiple pieces each having a size of 200 CI11 or less. In other words, the projected area is 200 CI11 or less.
The lower panels 2o of d and below are spaced apart from each other and the subfloor 5 is
The upper panel 10 is pasted on top of these so as to cover the gap between the lower panels 20. Note that the support plate 3 may be divided into multiple parts,
The support plate 3 and the first buffer layer 2 may be divided into a plurality of parts, with the first buffer layer 2 being a component of the lower panel 20.

The embodiment shown in FIG. 9 shows an arrangement in which a distribution/sound insulating layer 6 is provided between the surface finishing material 1 and the first buffer layer 2 in order to further improve the sound insulating performance. This vibration damping/sound insulating layer 6 is highly flexible and has a thickness of about 1 to 3 R, and is made of vinyl chloride,
Rubber or asphalt based materials are suitable for use.

This vibration damping/sound insulating layer 6 suppresses the sound produced when walking.
It gives a sense of weight and improves moisture resistance.

The embodiment shown in FIG. 1O is the same as the embodiment shown in FIG. 9, in which the surface finishing material 1 is chamfered and matt (5-minute gloss or less).

The embodiment shown in FIG.
And the first buffer layer 2 is laminated with a shift to prevent the upper panel 10 from sinking.

In the embodiment shown in FIG. 12, an example is shown in which the first buffer layer 2 constituting the upper panel 10 is constructed by combining two types of materials, and the end portion 2A, that is, the joint portion of the surface finishing material 1 is connected to the center portion 2.
This is made to be harder and prevents the occurrence of unevenness. The end portions 2A are made of a rubber-like elastic body or a foamed elastic body having a higher static spring constant than the center portion 2B.

The embodiment shown in Fig. 13 has the same effect as the embodiment shown in Fig. 12, and the thickness of the end portion 2A is made approximately 1 to 2 mm thinner than that of the central portion 2B, so that it can withstand a load equivalent to a light impact source. This is absorbed by the central portion 2B, and when a greater load is applied, the end portions 2A are brought into contact with the lower panel 20, thereby preventing the joint portion from becoming stepped.

In the embodiment shown in FIG. 14, the four circumferential portions of the lower panel 20 are cut out or actually processed to prevent the lower panel 20 from springing up.

In the embodiment shown in FIGS. 15 to 17, a cushioning material 7 is interposed around the four circumferences of the lower panel 20, so that the function of preventing floor noise caused by rubbing on the four circumferences is achieved.

The cushioning material 7 is preferably made of elastic foam or rubber-like elastic material, and is applied over the entire circumference or partially with a thickness of 1 mm or more.

In the embodiment shown in FIG. 18, a hole 8 is provided in the lower panel 20, and a cushioning material 9 is interposed between the holes 8 and the pegs 11 to secure the floor substrate 5 such as a concrete slab.
By using elastic foam or rubber-like elastic material for the cushioning material 9, the cushioning material 9 is taken out from the top surface so as not to impede the deterioration of the floor impact sound insulation performance. In addition, the code|symbol 12 is a washer. FIG. 20 shows the formation position of the hole 8 into which the peg 11 shown in FIGS. It is placed close to the top.

The lower panel 20 shown in FIGS. 21 to 25 each shows an example in which the structure of the second buffer layer is composed of a sheet-like elastic body having a protrusion shape on the back surface.

The lower panel 20 shown in FIGS. 26 and 27 has a second
The buffer layer 4 is made of an elastic long molded product, and this is shown embedded in the support plate 3.

The upper panel 10 shown in FIG. 28 is used in combination with a lower panel 20 in which the second buffer layer 4 is formed on the back surface of the support plate 3. The upper panel 10 constituting this second invention is
A first buffer layer 2 is formed on the back surface of the surface finishing material 1, and a temporary lining 13 such as veneer plywood is further formed on the back surface of the first buffer layer 2. That is, it has a structure in which the first buffer layer 2 is sandwiched between the surface finishing material 1 and the backing plate 13,
The upper panel 10 is less likely to warp. It is desirable that the backing plate 13 is made of the same material as the support plate 3. In this second invention as well, the thickness of the surface finishing material 1 is 6 mm or less, and the local load of the first and second buffer layers 2°4 is 100 cm, as described above.
! The material may have a static spring constant of 25 kg/aa-cm2 or less and have a thickness of approximately 1 to 4 nm, and may further include a damping/sound insulating layer between the surface finishing material 1 and the first buffer layer 2. It may be formed.

Alternatively, a lower panel 20 shown in FIG. 8 may be used.

(Effects) As explained above, according to the first invention, the first buffer layer is formed on the surface finishing material made of a relatively hard material such as wood or synthetic resin, or on the back surface of this surface finishing material. The upper panel is the upper panel, and the lower panel is the support plate sandwiched between the first buffer layer and the second buffer layer, such as veneer plywood, or the support plate and the second buffer layer. Lay the second buffer layer on the subfloor surface,
Next, the upper panel was attached to the lower panel so as to cover the butt points between the lower panels, so even if the lower panel and the upper panel were made larger than the conventional size, warping or misalignment would occur. This also makes construction easier. Additionally, since the upper panel covers the joints of the lower panel, it is possible to prevent the floor from sinking.

Furthermore, the completed floor will have at least four layers,
Since it includes the first and second buffer layers, it has excellent floor impact sound blocking performance.

According to the second invention, since the upper panel has the first buffer layer formed on the back surface of the surface finishing material and the backing plate further formed on the back surface of the first buffer layer, the upper panel does not warp. Since the on-site bonding work involves bonding the backing plate of the upper panel to the support plate of the lower panel, bonding is easier and workability is improved.

Further, even if the upper panel is warped, it is possible to press the lower panel with a pressing needle or the like. This is because nails can be driven into the backing board of the top panel.

In addition, the thickness of the surface finishing material is 6 mm or less, the thickness of the first buffer layer is approximately 1 to 4 mm, and the characteristics of the first buffer layer are 25 kg/cm-cn for a local load of 100-cm! If the floor is formed to have the following static spring constant, the overall thickness can be reduced, and as a result, the occurrence of floor sinking can be further prevented, and the existing carpet finish can be removed. It is also easy to install a lever floor covering. Furthermore, vibration damping and
In the case of products with sound insulation, the sound insulation performance is further improved, the weight is felt, and the moisture resistance is also improved. Furthermore, the thickness of the support plate is 21 or more, and the size is 20
For products that are divided into multiple pieces of 0 cal or less, the divided support plates follow the expansion and contraction of the surface finishing material, further suppressing warping and misalignment.
