Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor structure, and more particularly to a structure for connecting adjacent joists when assembling a double floor.

[0002]

2. Description of the Related Art Generally, a double floor having a soundproof structure is constructed as shown in FIG. A plurality of supporting legs 2 are attached to a long joist 1 formed of plywood or the like so as to protrude downward from the lower surface of the joist 1. The support legs 2 are provided at substantially equal intervals in the longitudinal direction of the joist 1. The support leg 2 is formed in a bolt shape so that the height can be adjusted.
Each support leg 2 is provided with an anti-vibration rubber 3 for imparting anti-vibration performance. The joists 1 are arranged at equal intervals so that a plurality of joists 1 are parallel to each other.
Is installed on the floor substrate 4. A sound absorbing material 5 is interposed between adjacent joists 1 so as to extend in the longitudinal direction. Further, a horizontal connecting plate 6 ′ is provided between the ends of the joists 1 to connect the adjacent joists 1. That is, the horizontal connecting plates 6 ′ having a length corresponding to the interval between the adjacent joists 1 are arranged between the adjacent joists 1, and the ends of the horizontal connecting plates 6 ′ are connected to the joists 1.
And is fixed by nailing the end of the horizontal connecting plate 6 '. The ends of the joists 1 adjacent in the longitudinal direction are connected by a vertical connecting member 11. After the joist 1 is installed in this way, the discarded plywood 8 is applied over the joist 1 and the floor finish 9 is applied over the entire surface of the discarded plywood 8.

[0003]

By the way, in the above-mentioned conventional example, a horizontal connecting plate 6 'is arranged between adjacent joists 1 and fixed by nailing. Occasionally, the joist 1 is overturned or displaced, resulting in poor workability and poor work accuracy.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and it is possible to easily and accurately connect adjacent joists with a horizontal connecting material, thereby improving workability and improving workability. It is in providing floor structure.

[0005]

According to a first aspect of the present invention, there is provided a double-floor structure in which a plurality of long joists 1 are arranged in parallel and a lower surface of each joist 1 is provided. A plurality of downwardly projecting support legs 2 are installed on a floor base 4 and a floor finishing material is pasted on the joist 1, and the horizontal connecting material 6 extending over the plurality of joists 1 is used as the joist. 1 are provided so as to be orthogonal to each other, and the lateral connecting members 6 are provided with fitting recesses 10 at intervals of each joist 1, and each joist 1 is fitted into the fitting recess 10 to form a plurality of joists 1. Are connected by a horizontal connecting member 9. The plurality of joists 1 are connected by the horizontal connecting members 6 by fitting the joists 1 into the fitting recesses 10 of the lateral connecting members 6 extending across the plurality of joists 1 orthogonally to the longitudinal direction of the joists 1. The joists 1 can be easily connected by the horizontal connecting members 6 without nailing in an unstable state as in the related art, and the interval between adjacent joists 1 is a predetermined interval. Can be connected with high accuracy, and the workability can be improved and the construction accuracy can be improved.

Further, the structure of the double floor according to claim 2 of the present invention is as follows:
In Claim 1, the cross-sectional shape of the joist 1 is made convex, and the shape of the fitting concave portion 10 of the lateral connecting member 6 is made convex,
It is characterized in that the joist material 1 is fitted into the fitting recess 10. By fitting the joist 1 having a convex cross-section to the fitting recess 10 having a convex shape, the joist 1 can be securely fitted so as not to come off, and can be securely connected by the horizontal connecting member 6.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a double floor according to the present invention is the same as that described in the above-mentioned prior art, and the only difference is the structure connected by the horizontal connecting member 6. Therefore, the description of the overlapping parts will be omitted, and only different points will be mainly described.
The joist 1 is a long object having a convex cross section. The joist 1 is provided with supporting legs 2 at substantially equal intervals in the longitudinal direction, and a vibration isolating rubber 3 is mounted on the lower end of the supporting leg 2. It is. The joists 1 are arranged so that the plurality of joists 1 are parallel to each other, and the vibration isolating rubber 3 at the lower end of each support leg 2 is installed on the floor base 4.
As described above, the sound absorbing material is interposed between the adjacent joists 1 in a state where the plurality of joists 1 are arranged and arranged in this manner. The horizontal connecting member 6 is a long object, and the horizontal connecting member 6 is provided with fitting recesses 10 at the same intervals as the intervals at which the joists 1 are arranged. The fitting recess 10 is formed in the same convex shape as the cross-sectional shape of the joist 1. The lateral connecting members 6 are arranged so as to be orthogonal to the longitudinal direction of the joist members 1 at the longitudinal ends of the joist members 1. At 6, a plurality of joists 1 are connected. Fitting recess 1
When the joist 1 is fitted to the part 0, this part may be fixed by nailing. In this case, since the joist 1 is fitted and positioned in the fitting concave portion 10, it can be easily nailed and fixed. The ends of the joists 1 in the longitudinal direction are connected by a vertical connecting member as in the prior art. After installing joist 1 as above,
A discarded plywood is stuck on the entire upper surface, and a floor finishing material is stuck on the discarded plywood to form a double floor with a soundproof structure.

[0008]

According to the invention of claim 1 of the present invention, a horizontal connecting member extending over a plurality of joists is arranged so as to be orthogonal to the joists.
Since the lateral joints are provided with fitting recesses at intervals of each joist and each joist is fitted into the fitting recess and a plurality of joists are connected by the lateral joints, the length of the joists is long. A plurality of joists can be connected by a horizontal connecting member by fitting the joists into the fitting recesses of the horizontal connecting members extending across the plurality of joists in a direction perpendicular to the direction. The joists can be easily connected with the horizontal connecting member without nailing in the unstable state, and the adjacent joists can be connected accurately so that the interval between them becomes a predetermined interval. In addition, the workability can be improved and the construction accuracy can be improved.

[0009] The invention of claim 2 of the present invention relates to claim 1 of the present invention.
In the above, the cross-sectional shape of the joist material is made convex, and the shape of the fitting concave portion of the lateral connecting material is made convex, and the joist material is fitted into the fitting concave portion. By fitting the shaped joists, they can be securely fitted so as not to come off, and can be securely connected by the horizontal connecting members.
