Description

[Detailed explanation of the idea] Traditionally constructed wooden joist floors are disadvantageous in terms of floor impact noise due to squeaking and resonance, and have been cited as one of the most serious noise problems in apartment complexes. It is.

The present application has been devised in view of these drawbacks, and the entire floor is supported on the beams around the room or on the walls at the beams via L-shaped cross-sectional support members,
A device related to a vibration-proof and sound-proof floor that acts as a vibration damper by preventing the impact from being transmitted to the center of the slab, which has less rigidity, and also acts as a sound barrier by spreading sand on the slab. It is.

Now, to explain the embodiment, a support member 1 for vibration isolation, such as vibration isolating rubber, having an L-shaped cross section and consisting of a rising part 1a and a horizontal part 1b, is attached to a peripheral corner part 6 of the room 5, and the rising part 1a is a wall. 7, or by attaching a support plate 8 to the wall 7 and providing the support member 1 above it so that the rising portion 1a abuts the wall 7. horizontal part 1 of
Several floor plate supports 2 such as I-beams, channels, or wooden shafts are laid in parallel on b, both ends of the floor plate supports 2 are supported by the rising parts 1a of the support members 1, and the floor plate supports 2 are A plurality of wooden joists 3 are arranged on the upper part of the wooden joists 3 so as to intersect at right angles to the floor plate supporting material 2 via vibration-proof parts 9, and a floor plate such as two sheets of plywood or aerated concrete plates is placed on the wooden joists 3. 4 is laid over the entire surface of the room 5.

Note that when a cellular concrete board is used as the floorboard 4, the wooden joist 3 is not necessary.

Furthermore, by spreading sand 12 on the slab 11, it can serve as a sound absorber.

Furthermore, horizontal movement of the floor plate supports 2 can be prevented by connecting the floor plate supports 2 at several points with horizontal joints 10 so that the intervals do not shift.

As described above, the present invention is to attach the rising part 1a of the L-shaped cross-sectional support member 1, which is composed of the rising part 1a and the horizontal part 1b for vibration isolation, to the wall 7 on the indoor beam or on the peripheral floor slab near it. Several floor plate supports 2 are arranged in parallel on the horizontal part 1b of the L-shaped cross-sectional support member 1, and the ends of the floor plate supports 2 are placed in contact with the rising part 1a, In addition, an appropriate number of wooden joists 3 are arranged through vibration-proofing parts 9 so as to intersect at right angles on the floor plate support material 2, and the floor plate 4 is laid on the wooden joists 3, or the floor plate 4 is laid on the floor plate support material 2. An appropriate number of anti-vibration pads 9 are directly placed, and the floorboard 4 is laid on top of it, and sand 12 is placed on the slab 11.
Since the entire floorboard rests on the beam, on the edge of the beam, or on the support member with an L-shaped cross section at the bottom of the wall, the shock is not transmitted to the center of the slab, which has less rigidity, and the rise The support member, such as a vibration isolating rubber, with an L-shaped cross section consisting of a horizontal part and a horizontal part, and vibration isolating pads have an extremely high performance in blocking floor impact noise, and the support member Since the rising part of the wall is in contact with the wall, in addition to the normal vibration-proofing effect, it also acts as a steady rest in the event of an earthquake.
Also, by laying sand on the slab, it also has a sound absorbing effect.
