Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-floor floor for an apartment house.

[0002]

2. Description of the Related Art It is well known that a floor of an apartment house has a double structure mainly for sound insulation. However, a floor of a conventional double structure for an apartment house has a floor base panel on a floor slab. The supporting legs for supporting are provided not only at the four corners of the floor base panel but also at the middle part thereof, the number thereof is relatively large, and a pass-through material is used for the support material (joist) of the floor base panel near the wall. Therefore, the material cost was relatively high.

[0003]

The problem to be solved by the present invention is that the support legs are provided only at the four corners of the floor base panel, and the material cost is reduced by using a short material for the support of the floor base panel near the wall. Another object of the present invention is to provide a double-structured floor for a multi-family housing with a new concept, which reduces the number of labors required for assembly and improves the degree of freedom in using the space under the floor.

[0004]

In order to solve the above-mentioned problems, according to the present invention, a double-structured floor for an apartment house is combined with a floor slab at a suitable height above the floor slab with a square planar shape. Floor base panels laid in parallel in a grid pattern,
A support leg erected on a floor slab and supporting corners of four floor base panels adjacent to each other with a seat plate at an upper end; and two adjacent floor bases which are relatively short in length and are fixed to a wall. Consists of a wall-side supporting material that supports a part of the side edge of the floor base panel at the corner of the panel or the corner of the room, and a misalignment preventing material attached between the longitudinal middle parts of adjacent floor base panels I am trying to do it.

[0005] In the double-floor floor for an apartment house according to the present invention, the supporting material near the wall is not made of wood but made of a steel angle material.
The vertical piece is fixed to the wall, and a part of the side edge of the floor base panel at the corner of the two floor base panels adjacent to the horizontal piece or the corner of the room is placed on the wall, and It is preferred that the floor base panel is firmly supported.

In the double-floor floor for an apartment house according to the present invention, a double-sided adhesive tape for fixing the floor base panel is attached to the mounting surface of each floor base panel of the support plate and the supporting plate near the wall. It is preferable to save labor for laying floor base panels.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an explanatory view of one embodiment of a double-structure floor for an apartment house according to the present invention;
2 is a floor base panel, 3 is a supporting leg, 4 is a supporting material near a wall, 5
Indicates misalignment preventing materials.

The floor base panel 2 has a square planar shape and is laid in a checkerboard pattern at a height H above the floor slab 1. In the case shown in FIG. The flooring 7 is laid on one side.

The support legs 3 are erected on the floor slab 1 below the intersections of the vertical and horizontal joints of the floor base panel 2 and are adjacent to the upper surface of a seat plate 8 having a square planar shape provided at the upper end thereof. Corners of the four floor base panels 2 are placed.

The corners of each floor base panel 2 supported by the seat plate 8 are fixed to the seat plate 8 by appropriate means such as nailing.
A double-sided adhesive tape is attached to the upper surface of the seat plate 8 in advance,
When the floor base panel 2 is fixed with this double-sided adhesive tape, the work is easy.

In the illustrated embodiment, the support leg 3 is formed by attaching a seat plate 8 to the upper end of a support bolt 9 in the same manner as a nut, and attaching an anti-vibration rubber 10 to the lower end of the support bolt 9. H is adjustable.

In the illustrated embodiment, the wall-side support member 4 which is a steel angle member is relatively short (about the length of one side of the seat plate 8), and the vertical and horizontal joints of the floor base panel 2 intersect with the wall 11. The floor base panels 2 at the corners of the room are respectively provided at places where the floor base panels 2 are in contact with the wall 11, and the vertical pieces 12 are fixed to the wall 11 with bolts 13.

The horizontal piece 1 of the wall-side support member 4 is disposed at a location where the vertical and horizontal joints of the floor base panel 2 intersect with the wall 11.
4, the corners of two adjacent floor base panels 2 are placed, and the floor base panel 2 at the corner of the room is placed on the wall 1.
A part of one side of the floor base panel 2 at the corner of the room that is in contact with the wall 11 is placed on the horizontal piece 14 of the wall-side support member 4 installed at the place where the wall 1 contacts.

In this case, the floor base panel 2 mounted on the upper surface of the horizontal piece 14 can be fixed easily and reliably via the double-sided adhesive tape 15 previously attached to the upper surface of the horizontal piece 14. it can.

In the case of the drawing, the bolt holes 16, 16 of the vertical piece 12 of the wall-side support member 4 are formed to be elongated horizontally for position adjustment in the horizontal direction, and the tip of the bolt 13 is bent. The tip of the bolt 13 can be changed by rotating the tapered hole 17 in a tapered hole 17 formed in the wall, and the tapered hole 17 is filled with mortar or the like later to fix the bolt 13.

The misalignment preventing material 5 is installed between the middle portions of the adjacent floor base panels 2 in the longitudinal direction. When the installation is performed in parallel with the laying of the floor base panel 2, for example, FIG. When the installation is performed after the floor base panel 2 is laid, for example, a rotating metal fitting 19 as shown in FIG. 6 can be used. The replacement of the panel 2 is easy.

The rotating bracket 19 is formed by attaching horizontal bars to upper and lower ends of a vertical bar, and passing the lower bar through a joint 20 between the adjacent floor base panels 2 and 9.
It is designed to be rotated 0 degrees and attached.
