Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a technique for preventing lifting of the edges of a flooring material having soundproofing and vibrationproofing functions.

[Background technology] Conventional flooring materials, for example, are simply a decorative board (veneer) pasted on a substrate made of plywood.
When a floor material receives a direct impact, vibrations are transmitted through the floor material to the floor base material of the building, which is problematic in that it is transmitted to the lower floors, which is not desirable in terms of soundproofing. For example, in apartment complexes such as condominiums, there was a problem that if children ran around on the upper floors, the people on the lower floors would complain about the noise. Therefore, the flooring material is constructed by laminating cushion material on the underside of the wooden flooring material.
It has been considered that the cushioning material absorbs the impact applied to the upper surface of the flooring material by bonding or nailing this flooring material to the floor substrate. However, in this conventional example, when the lower part of the cushion material is glued to a subfloor such as a concrete floor, the upper layer is the main body of the wood flooring material, so when it is installed, the side edges are on top. There is a risk that the joints may warp and become difficult to walk on.Also, if the edges of the flooring material are nailed to the subfloor, warping can be prevented, but nailing When this happens, the cushion material is compressed, and the nails are stuck in the compressed state of the cushion material, so the edge of the flooring material where the nails were driven is depressed downward compared to the other parts, which not only results in a poor finish but also makes it difficult to walk on. There was also the problem of bad sex.

[Purpose of the invention] The present invention was devised in view of the above-mentioned problems, and its purpose is to prevent the lifting of the ends and also to prevent the fixing fittings from sinking when fixed. At the same time, there is no fear that the head of the fixing tool that fixes the lower horizontal piece of the fixing metal fitting to the flooring substrate will become an obstacle, making it impossible to fit the convex part and the concave part for joining the flooring materials together. An object of the present invention is to provide a mounting structure for a flooring material having soundproofing properties.

[Disclosure of the invention] The installation structure of the flooring material of the present invention includes a wooden flooring material body 1
A floor material 3 is formed by laminating cushion material 2 on the lower surface of the floor material 3, protrusions 4 and recesses 5 for joining are provided on the sides of the floor material 3, and a vertical piece 6b is formed downward from one end of the upper horizontal piece 6a. The upper horizontal piece 6a of the fixture 6, which has a substantially Z-shaped cross section, is constructed by protruding from the lower end of the vertical piece 6b in the opposite direction to the upper horizontal piece 6a. The lower horizontal piece 6c is fixed to the lower surface and protrudes laterally from the flooring material 3, and the lower surface of the lower horizontal piece 6c is positioned near the same level as the lower surface of the cushion material 2, and the flooring material 3 is attached to the flooring material 7. The lower horizontal piece 6c is fixed to the floor base 7 with the fixing tool 8, and the convex part 4 provided on the side end surface of one flooring material 3 and the other flooring material 3 are connected to each other. The recess 5 provided on the side end surface of the recess 5 is fitted into the recess 5, and by employing such a configuration, the above-mentioned object of the present invention is achieved.
That is, in the present invention, the presence of the cushion material 2 on the lower surface of the flooring material 3 not only provides soundproofing and vibration-proofing effects, but also provides vertical pieces 6b that protrude downward from one end of the upper horizontal piece 6a. Further, the upper horizontal piece 6a of the fixture 6, which has a substantially Z-shaped cross section and is constructed by protruding a lower horizontal piece 6c from the lower end of the vertical piece 6b in the opposite direction to the upper horizontal piece 6a, is fixed to the lower surface of the end of the flooring main body 1. At the same time, the lower horizontal piece 6c protrudes laterally from the flooring material 3, the flooring material 3 is laid on the flooring substrate 7, and the lower horizontal piece 6c is fixed to the flooring substrate 7 with the fixing tool 8, thereby securing the floor. The cushioning material 2 prevents the ends of the material 3 from lifting up, and the lower surface of the lower horizontal piece 6c
By locating it near the same level as the bottom surface, even if the fixing fitting 6 is fixed to the flooring base 7 with the fixing device 8, the end part will not be fixed in a sunken state, and the concave part 5 and convex part Not only can the end parts of adjacent flooring materials 3 be connected without a step by fitting with the part 4, but also the fixing metal fittings 6 have a substantially Z-shaped cross section, and the lower horizontal piece 6
By fixing c to the flooring substrate 7 with the fixing tool 8, the head of the fixing tool 8 does not directly contact the lower surface of the flooring main body 1, and therefore is not interfered with by the head of the fixing tool 8. In addition, the upper horizontal piece 6a of the fixture 6, which has a substantially Z-shaped cross section, is fixed to the lower surface of the flooring main body 1, so that the lower horizontal piece 6a can be fitted without any problem. 6c can be made approximately the same level as the lower surface of the cushion material 2 as set.

The present invention will be explained in detail below with reference to Examples. Cushion material 2 is laminated and integrated on the lower surface of a wooden floor material body 1 to form a floor material 3. A convex portion 4 to a concave portion 5 for joining are provided on the side of the floor material 3. Furthermore, a fixing fitting 6 is fixed to the lower surface of the end of the flooring main body 1. The fixing fitting 6 has a vertical piece 6b projecting downward from one end of the upper horizontal piece 6a, and a lower horizontal piece 6c protruding from the lower end of the vertical piece 6b in the opposite direction to the upper horizontal piece 6a. It has an approximately Z-shaped cross section. and,
The upper horizontal piece 6a of the fixture 6, which has a substantially Z-shaped cross section, is placed against the lower surface of the end of the flooring main body 1 and fixed using a fixing tool 15, an adhesive, or the like. In this case, a part of the end of the cushion material 2 is cut out to expose the lower surface of the floor material body 1, and the upper horizontal piece 6a is attached to the lower surface of the exposed end of the floor material body 1.
(See Figure 2). In addition, when the upper horizontal piece 6a of the fixing fitting 6 is fixed to the lower surface of the end of the flooring main body 1 as described above, the lower horizontal piece 6a
c is made to protrude laterally from the flooring material 3. Further, the lower surface of the lower horizontal piece 6c is a cushion material 2.
The lower surface of the lower horizontal piece 6c is approximately at the same level as the lower surface (preferably, the lower surface of the lower horizontal piece 6c is slightly above the lower surface of the cushion material 2). In this case, by setting the vertical height of the vertical piece 6b to be approximately the same as the thickness of the cushion material 2, as described above, the upper horizontal piece 6a
The lower surface of the lower horizontal piece 6c can be automatically made substantially flush with the lower surface of the cushion material 2 by simply fixing it to the lower surface of the floor material body 1.

Then, the flooring material 3 is laid on a floor substrate 7 such as a concrete slab or a joist, and the lower horizontal piece 6c of the fixing fittings 6 protruding laterally from the flooring material 3 is attached to a concrete nail 8a, a screw nail 8b, or a fixing device 8 such as a nail. Underfloor 7
The convex portions 5 to 4 of the adjacent flooring material 3 are fitted into the convex portions 4 to the concave portions 5 on the sides of the flooring material 3, thereby forming the flooring material 3.
It joins them together. And lower horizontal piece 6c
Since the lower surface of the fixing member 6 is substantially flush with the lower surface of the cushion material 2, the lower horizontal piece 6 of the fixing metal fitting 6 has a substantially Z-shaped cross section.
c is fixed to the flooring substrate 7 with the fixing tool 8, the cushion material 2 is not compressed much in the part of the floor material 3 where the fixing fitting 6 is provided by driving the fixing tool 8, and this part is partially compressed due to fixing. It is something that will not collapse. Furthermore, since the flooring materials 3 are joined by fitting the convex portions 4 and the concave portions 5, not only can steps be prevented from occurring at the joints, but also the lower horizontal piece of the fixing bracket 6
By fixing c to the floor base 7, it is possible to prevent the joint portion where the convex portion 4 and the concave portion 5 are fitted together from warping upward.

Further, the upper horizontal piece 6a of the fixing metal fitting 6 having a substantially Z-shaped cross section
is fixed to the lower surface of the end of the flooring main body 1, and the lower horizontal piece 6c is fixed to the flooring base 7 by the fixing device 8, so that the fixing device 8 is attached upward from the upper surface of the lower horizontal piece 6c, as shown in FIG. Even if it protrudes, it bites into the cushion material 2 of the adjacent flooring material 3, and the head of the fixing tool 8 comes into direct contact with the lower surface of the flooring material body 1, lifting the flooring material body 1 upward and forming the convex portion 4 and the concave portion 5. This eliminates the possibility that the two parts cannot be properly fitted. Here, if necessary, a part of the end of the cushion material 2 of the adjacent flooring material 3 is cut out to form a notch 17, and the lower horizontal piece, which is the lateral protrusion of the fixing metal fitting 6, is inserted into the notch 17. 6
The head of the fastener 8 may be located in the notch 17, and this will not interfere with the fitting between the protrusion 4 and the recess 5. Also, if the subfloor 7 is a concrete slab,
As shown in Fig. 3, a pilot hole 18 is drilled in the flooring base 7 in advance, and a screw nail 8b is inserted into the pilot hole 18.
The fixing metal fitting 6 may be fixed by screwing them together. In the present invention, the fixing fittings 6 are provided on the long side or the short side of the flooring material 3, or on both the long side and the short side, and are long or short along the long side or the short side. It will be done. Fourth, a specific example of the flooring material 3 is shown. In FIG. 4, a wooden floor material body 1 is made of a board-like material 10 such as plywood with a veneer-like veneer 9 pasted on its surface, such as a vinyl chloride sheet containing barium sulfate and having a high specific gravity. It is laminated on a substrate 12 such as plywood through a sound insulating sheet 11, and there are two types: one with grooves 13 provided on the back side of the substrate 12 and one without grooves 13 as shown in the attached drawings. However, when providing the cut grooves 13, the cut grooves 13 are cut from the back side of the substrate 3 to the sound insulation sheet 11, or cut to a state that does not reach the sound insulation sheet 11, or the cut grooves 13 with different cutting depths are used together. It can also be used as Further, one or more kerfs 13 may be provided in parallel to the longitudinal direction of the flooring main body 1, or one or more kerfs 13 may be provided in the width direction of the flooring main body 1,
Alternatively, one or more pieces may be provided in the longitudinal direction and the width direction of the flooring main body 1, or one or more pieces may be provided in the diagonal direction with respect to the longitudinal direction of the flooring main body 1, or the flooring main body 1 They may also be provided in a diagonal lattice shape that is diagonal to the longitudinal direction. Further, the groove width, groove depth, and pitch of the cut groove 13 may be arbitrary. A cushion material 2 is bonded to the back surface of the substrate 12 with an adhesive. The cushion material 2 is, for example, a rubber foam, but is not necessarily limited to this and may be of other materials. The side portions of the flooring body 1 are provided with convex portions 4 to concave portions 5 for joining.
A convex portion 4 is provided protrudingly on two side surfaces of, and the remaining two adjacent
A recess 5 is formed on the side surface. Further, a fixing part 6 is provided at the lower part of the flooring material 3 so as to protrude laterally from the flooring material 3. Also in this embodiment, the flooring material 3 is laid on the flooring base 7, the lower horizontal piece 6c of the fixture 6 is fixed to the flooring base 7 with the fixing tool 8, and the flooring materials 3 are fitted together with the convex part 4 and the concave part 5. They are joined together. A fourth like this
In the embodiment shown in the figure, not only the sound insulation sheet 11 has a sound insulation effect, but also the grooves 13 attenuate the propagation of vibrations from the surface of the flooring material 3 and prevent the transmission of sound. It is something that
By the way, like this, there is a cut groove 1 on the back side of the flooring main body 1.
3, the flooring material 3 will tend to warp so that the edges are upward, but in the case of the present invention, a fixing metal fitting 6 is provided at the bottom of the flooring material 3 and protrudes laterally from the flooring material 3. Warping of the floor material 3 is prevented by fixing the lower horizontal piece 6c to the floor base 7.

Note that a long hole is bored in the upper horizontal piece 6a of the fixing metal fitting 6,
When attaching the upper horizontal piece 6a to the flooring main body 1 using the elongated hole with the fixing tool 15 and fixing the lower horizontal piece 6c to the floor base 7 such as a concrete slab, insert the fixing tool 8. Even if the fixing tool 8 is misaligned and fixed when doing so, the fixing tool 15 slides with respect to the elongated hole so that it can be absorbed.

[Effects of the invention] As mentioned above, in this invention, the flooring material is formed by laminating the cushion material on the bottom surface of the wooden flooring material body, so of course it has a soundproofing and vibrationproofing effect. , an upper horizontal piece of a fixing bracket having a substantially Z-shaped cross section, which is constructed by a vertical piece protruding downward from one end of the upper horizontal piece, and a lower horizontal piece protruding from the lower end of the vertical piece in the opposite direction to the upper horizontal piece. is fixed to the lower surface of the end of the flooring main body, the lower horizontal piece protrudes laterally from the flooring, the flooring is laid on the subfloor, and the lower horizontal piece is fixed to the subfloor using a fixing tool.
It is possible to prevent the edges of the flooring material from lifting up, and since the bottom surface of the lower horizontal piece is located at approximately the same level as the bottom surface of the cushion material, the edges will not sink even if the fixing bracket is fixed to the flooring base with the fixing tool. In addition, by fitting the concave part and the convex part, the ends of adjacent flooring materials can be connected without any difference in level, and the fixing metal fittings are By fixing the lower horizontal piece, which has an approximately Z-shaped cross section, to the subfloor using a fixing device, the head of the fixing device does not directly hit the bottom surface of the flooring main body, and therefore the head of the fixing device The fitting between the concave part and the convex part can be carried out without any problem without being disturbed by The level can be set to be approximately the same level as the lower surface of the cushion material. As described above, the present invention has excellent soundproofing and vibration resistance, the edges do not lift up, cave in, or have any steps, and the recessed part and the convex part fit securely. This provides a flooring installation structure that allows for
