Description

[Detailed description of the invention] This invention relates to improving the soundproofing properties of floor panels.
The lower surfaces of both ends of the ceiling base rail 1 are cut out to form holding ends 2 at both ends of the ceiling base rail 1, and horizontal upper and lower lip pieces 4a, 4 are formed.
A presser piece 6 is provided on the inner surface of the frame 5, which has a substantially U-shaped cross section and has a substantially U-shaped cross section, protrudingly provided in parallel with the lip pieces 4a and 4b. 5, the holding end 2 is inserted between the lower lip piece 4b and the holding piece 6, and the cushioning material 3 covering the surface of the waist holding end 2 is placed between the lower surface of the holding piece 6 and the upper surface of the holding end 2. In a conventional floor panel, which is a floor panel that is interposed between
A panel frame 8' is formed by the frame 5' and the panel frame 8', and a subfloor material 9' that will become the floor of the second floor is placed on the upper surface of the joists 7' of the panel frame 8'.
Ceiling finishing material 10', which will become the ceiling of the first floor, was attached to the lower surface of the same joist 7' with nails 11'.

However, in such conventional examples, the flooring material was attached to the upper surface of the joists and the ceiling finishing material was attached to the lower surface of the joists, so noise and vibrations generated on the second floor (especially the second floor floor) were transmitted through the joists. directly 1
The problem was that the sound and vibrations from the second floor were easily transmitted to the first floor because the ceiling finishing material acted as an alarm board.

This invention was made in view of the conventional shortcomings of Narukami, and its purpose is to provide a floor panel with excellent soundproofing and vibration-proofing effects that prevents sound and vibrations from the second floor from being transmitted to the first floor. be.

The present invention will be explained in detail below with reference to the accompanying drawings.

In the figure, reference numeral 1 is a ceiling base sill. The lower surface of both ends of the ceiling base sill 1 is cut out to form holding ends 2 at both ends of the ceiling base sill 1. The surface of the holding end 2 is made of foamed polystyrene or rubber. It is covered with a cushioning material 3 such as.

For this purpose, a cap-shaped or cylindrical cushioning material 3 may be placed over the holding end, or a band-shaped cushioning material 3 may be placed on the holding end 2.
You can also wrap it around the surface of

5 is a lip piece 4a horizontally above and below the upper and lower edges of the main piece 12;
, 4b are extended to form a substantially U-shaped cross section, and furthermore, horizontal holding pieces 6 are provided at approximately the upper and lower center of the inner surface of the main piece 12 at multiple locations spaced apart at regular intervals along the longitudinal direction of the frame 5. A pair of clamping pieces 13 are cut and raised from the main piece 12 below both sides of each presser piece 6.

Reference numeral 14 denotes a joist stopper placed on the upper surface of the lower lip 4b along the longitudinal direction of the frame 5.

Then, the pair of frames 5 are arranged to face each other in parallel with the protruding sides of the lip pieces 4a and 4b facing inward, and the holding end 2 of the ceiling base rail 1 is held together with the cushioning material 6 by the holding pieces (6), and the pair of The ceiling base beam 1 is fitted between the two frames 5 by fitting into the holding part 15 surrounded by the clamping piece 13 and the joist stopper 14, and the upper lip 4a of the frame 5 is attached to both ends of the joist 7.
Both frames 5 are fitted between the lower surface and the upper surface of the joist stopper 14.
A joist 7 is installed between them, and the joists 7 and ceiling underlayment beams 1 are arranged alternately in this way. Another frame 5 is installed between the ends of both frames 5, and a floor underlayment material 9 is installed on the upper surface of the joists 7. The floor panel A is formed by pasting the .

The floor panel A is arranged between the second floor and the first floor to constitute the floor of the second floor, and a ceiling finishing material 10 is attached to the lower surface of the ceiling base beam 1 with nails 11 to form the ceiling of the first floor. It consists of

α is a gap formed between the lower surface of the lower lip piece 4b of the frame 5 and the upper surface of the ceiling finishing material 10.

As described above, in the present invention, the end of the joist is inserted between the upper and lower lip pieces of the frame, and the holding end with the lower part cut out is inserted between the holding piece and the lower lip piece of the frame. If the bottom surface of the ceiling base rail is located below the bottom surface of the joist and a ceiling finishing material is attached to the bottom surface of the ceiling base joist, the joist and ceiling finishing material will be separated and do not come into contact with each other, and therefore the second floor (
In particular, the sound and vibrations generated on the second floor floor do not propagate to the first floor ceiling through the joists, and the ceiling finishing material does not vibrate, resulting in excellent soundproofing and vibrationproofing effects.

In addition, since the top surface of the ceiling base rail is pushed downward by the holding piece protruding from the frame, the ceiling base rail may retract into the floor panel when sealing the ceiling finishing material to the bottom surface of the ceiling base rail. There is no such thing.

Furthermore, even though the holding end is pressed downward by the holding piece, a cushioning material is interposed between the upper surface of the holding end and the lower surface of the holding piece, so vibrations of the holding piece are prevented. is absorbed by the cushioning material and is not transmitted to the ceiling finishing material, resulting in even more soundproofing.
It has the advantage of increasing the vibration damping effect.
