Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an end of a floor supported at a predetermined height from above a concrete slab by supporting legs having a height adjustable, which is used in an apartment house, a gymnasium, etc. The present invention relates to a floor end structure exhibiting high floor impact sound insulation performance.

[0002]

2. Description of the Related Art In a conventional floor, as shown in FIG. 10, a floor base panel 1 having a predetermined size is supported at a predetermined height from a floor base 3 such as a concrete slab by supporting legs 2 to form a plurality of floors. The floor base panel 1 is laid and the damping material 4 is placed on the floor base panel 1.
Is provided, and the sacrificial material 5 is provided on the damping material 4, and the finishing material 6 is provided on the sacrificial material 5. The end of such a floor was in contact with a room partition member 10 such as a sill, and the ends of the cutout material 5 and the finishing material 6 were supported by the joist 11 at this point. The support leg 2 is provided with a cushion rubber 2B at the lower end of a height-adjustable support bolt 2A to achieve sound insulation. Also,
The joist 11 suppresses the amount of sinking at the floor end when a load is applied to a portion corresponding to the entrance of the room, and the sinking of the end of the finishing material 6 and the sill (room partition member) 10
This is to prevent rubbing noise (floor noise). Further, at this time, the joist 11 is also used to prevent a gap from being generated between the finishing material 6 and the sill 10 and an uplift when the entire floor expands and contracts.

[0003] In the above-mentioned conventional example, the sound insulation performance at the floor edge portion was poor because of the lack of vibration damping performance of the portion of the joist 11.

Accordingly, a floor end structure as shown in FIG. 11 has been developed. That is, the joist 11 is connected to the supporting legs 19 with rubber.
By supporting the floor, the sound insulation performance at the floor edge is improved.

[0005]

In the conventional example shown in FIG. 11, the floor joist 11 is not fixed in the horizontal direction, and the lower end is supported by rubber, so that a slight sinking occurs. There was a gap between the end and the sill 10, and floor noises occurred.

Accordingly, the present invention prevents floor noise caused by sinking of the floor end without lowering the floor impact sound insulation performance.
It is an object of the present invention to provide a floor end structure capable of concealing a gap even if a gap is formed between a room partition member and a floor end due to expansion and contraction of a floor material.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention relates to a floor partition supported at a predetermined height from a floor base such as a concrete slab by supporting legs and a room partition member such as a sill. A parting material is provided between the two, and a bent portion is formed at the upper end of the vertically long plate-like portion sandwiched between the end of the floor and the room partition member, the bent portion being bent toward the floor and the tip pressed against the floor surface. The parting material is formed, and at least the bent part of the parting material has flexibility.

[0008]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a so-called dry double floor is constructed in the same manner as in the prior art, and the ends of such a floor, that is, the ends of the piling material 5 and the finishing material 6 and the sill rising from the floor base 3, etc. A parting material 20 was provided between the room partition member 10 and the room partition member 10. A vertically long plate-like portion 21 sandwiched between the end of the floor and the room partition member 10
At the upper end, an arc-shaped bent portion 22 is formed, which is bent toward the floor and whose tip is pressed against the floor surface, to form the parting-off member 20. And the bent part 22 of the parting material 20 has flexibility. In this embodiment, the plate portion 21 is fixed to the room partition member 10 with a nail 12 (or a screw).

FIG. 2 shows a side view of the parting member 20. In this embodiment, the width of the plate-like part 21 is different from that of the room partition member (sill) 10
, But a plurality of parting members 20 shorter than the length of the room partition member 10 may be provided. The plate portion 21 of the parting member 20 is formed of a hard material, and the bent portion 22 is formed of a soft material. This plate portion 21
As a material for forming the bent portion 22, a vinyl chloride-based material, an olefin-based resin material, and a rubber-based material are preferable. Note that the plate portion 21 may also be formed from a soft material.

In another example of the parting member 20 shown in FIG. 3, an overhang portion 23 is provided on the opposite side of the bent portion 22, and the presence of the overhang portion 23 allows the plate-like portion 21 and the room partition member 10 such as a threshold. Can be blinded. At the same time, the presence of the overhang portion 23 can prevent the accumulation of minute dust in the gap formed between the room partition member 10 and the plate-shaped portion 21.

In the parting member 20 shown in FIG. 4, a double-sided adhesive tape 24 is provided on the back surface of the plate-shaped portion 21 so that the plate-shaped portion 21 is fixed to the room partition member 10 such as a sill. That is, the nail 12 is used in the embodiment shown in FIG.
4 is used. By providing the double-sided adhesive tape 24 on the back surface of the plate-shaped portion 21 in advance, mounting of the parting material 20 to the room partition member 10 becomes easy.

An example of the parting material 20 shown in FIG.
1 shows an example in which a buffer 25 is provided on the side of the floor end. The buffer 25 comes into contact with the end of the floor, does not form a sound bridge, can ensure sound insulation performance, and helps prevent floor noise.

FIG. 6 is a view showing a state before the finishing material 6 is constructed, and the parting material 2 is higher than the height of the floor surface 6A of the finishing material 6.
The tip of the zero bent portion 22 is below. When the finishing material 6 is applied, the tip of the bent portion 22 comes into pressure contact with the floor surface 6A.

In the embodiment shown in FIG. 7, a wall is shown on the right side as a member for partitioning a room together with a threshold, and a partition member 20 is also provided at a position of a room partition member 10 composed of this wall.
Reference numeral 13 denotes a baseboard.

In the graphs shown in FIG. 8 and FIG. 9, the reference numeral X indicates the conventional example shown in FIG. 10, and the reference numeral Y indicates the embodiment of the present invention shown in FIG. FIG. 8 shows the results of comparison of heavy floor impact sounds, and FIG. 9 shows the results of comparison of lightweight floor impact sounds. The measurement method for obtaining the results shown in FIGS. 8 and 9 was based on JIS A-1418. The display of L-40 to L-65 indicates the sound insulation grade, and L-40 indicates the best level according to JIS grade.

[0017]

As described above, according to the present invention,
A parting material is provided between the room partition member and the floor end, and the parting material is a plate-shaped portion to be attached to the room partition member and a bent portion bent from the upper end of the plate-shaped portion to the floor side in an arc shape. Since the tip of the bent portion is in pressure contact with the floor surface, it is possible to prevent the floor end portion and the room partition member from rubbing each other and generating floor noise. Further, even when the floor material expands and contracts, the gap is hidden by the bent portion. Further, the floor structure that maintains the predetermined height with the support legs does not lower the floor impact sound insulation performance originally provided.
