Description

[Detailed Description of the Invention] [Technical Field 1] The present invention relates to a vibration-proof floor for a wooden house.
As shown in the figure, a vibration-proofing floor is constructed by interposing vibration-proofing rubber 8 as a vibration-absorbing material between the horizontal member 1 and the floor joist 3' and between the joist 3' and the floor material 4. However, the anti-vibration rubber 8
The mounting method was complicated, the thickness of the vibration isolating rubber 8 was required to be uniform, and there was also concern about the fixation between each member, which resulted in poor construction.

[Objective of the Invention 1 The present invention has been made in view of the above v1s (/? An object of the present invention is to provide a vibration-proof floor that can exhibit a vibration-proofing function.

[Disclosure 1 of the Invention The vibration-isolating floor of the present invention is a floor joist 3 that has vibration-isolating rubber plates 2 interposed over the entire length of the longitudinal direction and the width direction of a structural cross member 1 such as a cross member or a beam. With this structure, the above object can be achieved. That is, since the vibration isolating rubber plate 2 is interposed on the joist 3, unlike the conventional method,
There is no need to use anti-vibration rubber between the members, and the fixing of the members is stable, resulting in excellent workability. 2 is interposed, solid-borne sound can be reliably blocked, and a reliable vibration-proofing function can be achieved.

Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In the embodiment shown in FIG. 1, 9! :g
A flat anti-vibration rubber plate 2 is interposed therein. This anti-vibration rubber plate 2 has the same length and V width as the joist 3, and is made by cutting the joist 3 into equal parts vertically and gluing it between the wooden parts with WCN agent, so that it has a large length over the entire length in the receiving direction and width direction. It has been assisted. This joist 3 is made of wood and looks like a beam, and is fixed by passing the frame between the J-shaped horizontal members 1. A floor base 4a is attached to the joist 3, and a floor surface material is attached to the floor base 4a to provide vibration isolation. The floor consists of 1MiM2
Attachment to the O3 cross member 1 is performed by driving nails 5 diagonally from below the vibration-proof rubber plate 2, as shown in Figure @3. The installation of the subfloor 4& can be done by hitting the nails 6 to the top. When only a decorative material such as a decorative floor or flooring is used as the flooring material 4, a hidden needle 7 is provided from part 'A'.

In the embodiment shown in Fig. tPJ4, the vibration isolating rubber plate 2 has a V-shaped cross section, and in this case, the attachment of the joists 3 to the horizontal members 1 of the structure a, and the attachment of the flooring 4 to the joists 3. The attachment is carried out in the same manner as in the above embodiment, as shown in FIG. In this embodiment, when the 11-F vibrating rubber plate 2 is in the form of a flat plate as in the above embodiment, the joist 3 is cut vertically into equal parts to suppress a decrease in the strength of the joist 3 in this case. This is what I did.

That is, as shown in FIG. 7, the joists 3 in FIG. 2 are cut vertically in a straight line in accordance with the shape of the vibration isolating rubber plate 2, whereas in this embodiment, the joists 3 are cut vertically in a straight line. In this case, the resistance to bending of the joist 3 against the load depends on the thickness of the upper and lower joist segments 3a, 31J, and therefore, compared to the embodiment shown in FIG. L 3 +L
, > L + + L 2, and the resistance increases. Furthermore, as shown in Fig. 8, in the case of the horizontal vibration in the width direction of the joist 3, the tearing resistance of the anti-vibration rubber plate 2 in the joist 3 shown in Fig. 2 is 11 hours, so the vibration absorption coefficient is different from the vertical vibration. Although different, compression and stretching forces act on the vibration isolating rubber plate 2 of this embodiment, resulting in a stable vibration absorption rate equal to that of vertical vibration. It should be noted that even in the case of horizontal vibration, there is no difference between the two in the receiving direction. Moreover, in this embodiment, the contact area between the vibration-proof rubber plate 2 and the joists 3 is increased, and the adhesive strength can be increased.
Stability against horizontal forces in the width direction also increases.

[Effect of the invention 1] In the present invention, flooring is attached to structural cross members such as beams and beams through joists with anti-vibration rubber plates interposed over the entire length in the receiver direction and width direction. This eliminates the need for anti-vibration rubber to be interposed between the members as in the past, and the fixing of the members is also stable, resulting in excellent workability. Since the vibration isolating rubber plate is interposed over the whole area, solid-borne sound can be reliably blocked and a reliable vibration damping function can be achieved.
