DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double floor support device.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional double floor supporting apparatus. In this conventional example, a support leg insertion hole 10 is formed in the center of the cradle portion 8, and the support leg insertion hole 10 is fitted to the upper end of the support leg 2 erected on the floor slab 1. Is welded. The boss 1 is provided on the surface of the cradle 8.
1 is protruded, and is positioned by the boss 11 to support a floor member such as a floor panel (not shown).
In the drawing, reference numeral 12 denotes a fixing member receiving member having a screw hole 12a formed therein, which receives a bolt for fixing the floor member 4 to the support leg 2.

[0003]

However, in the above conventional example, since the pipe material forming the support leg 2 has a variation in roundness, the center of the screw hole 12a and the center of the support leg 2, and Since it is difficult to accurately match the center of the cradle portion 8 with the center of the support leg 2, the positioning boss 11 of the floor member 4 formed on the cradle portion 8 and the floor member 4 are fixed. Error tends to occur in the positional relationship of the screw holes 12a into which the bolts are screwed, which may hinder the mounting of the floor member.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a double-floor support device capable of improving the assembling accuracy of a double-floor.

[0005]

According to the present invention, there is provided the above object.
Is a double bed supporting device for supporting the floor member by floor pan member fixed to the upper end of the support leg provided to stand at a predetermined pitch on the floor slab, the floor pan member, positioning the floor member And the fixing member consisting of bolts
A pedestal part with a bolt insertion hole
A fixing member receiving portion is provided on the back side of the well wall, and in the ceiling wall,
The support leg is joined to the back surface of the upper plate of the cradle portion.
And a cap member fitted and fixed to an upper end of the cap member , wherein the floor member is fixed on the floor receiving member by a fixing member received by a fixing member receiving portion of the cap member. It is achieved by doing.

[0006]

In the present invention, the floor receiving member 3 has a cap member 6 fixed to the support leg 2 and a pedestal portion 8, and the cap member 6 and the pedestal portion 8 are fixed to each other. 9 together. The fixing member receiving portion 5 for receiving the fixing member 9 is formed on the cap member 6, and the positioning portion 7 for positioning the floor member 4 is formed on the receiving base portion 8. The positional relationship is always kept constant, and the construction state of the floor member 4 can be kept constant.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 3 shows a double floor to which the present invention is applied. The floor member 4 in this double floor is composed of a beam 13 laid on a support device, a panel support member 14 laid over the beam 13, and floor panels 15, 15.・ It is composed of

FIGS. 1 and 2 show details of the supporting device.
A supporting leg 2 erected on the floor slab 1, a floor receiving member 3 fixed to the upper end of the supporting leg 2, and a bolt (fixing member 9) for fixing the floor member 4 to the floor receiving member 3. It is composed of

The support leg 2 has a screw 2b erected on the floor slab 1 via a fixing plate 2a, a nut 2c screwed to the screw 2b, and a lower end held by the nut 2c. A pipe body 2d such as a steel pipe, and a detent bolt 2e which is inserted through the pipe body 2d and whose tip is pressed against the nut body 2c.
The installation height can be adjusted by rotating the nut body 2c up and down along the screw rod 2b.

On the other hand, the floor receiving member 3 has a cruciform upper surface plate 3a having a receiving base 8 for fitting and holding the beam 13 on its surface, and a reinforcing member joined to the back surface of the upper surface plate 3a. The upper surface plate 3 is composed of a plate 3 b and a cap member 6.
a, bosses (positioning portions 7) protruding in the vicinity of four corners for positioning the beam 13, concave portions 16 for accommodating washers 17, and bolt insertion holes 18 drilled at the center of the concave portions 16; Is provided.

The inner diameter of the cap member 6 is
d, and is joined to the back surface of the upper surface plate 3a at the ceiling wall. A nut (fixed member receiving portion 5) into which the bolt 9 is screwed is welded to the cap member 6, and as shown in FIG.
The beam 13 is fixed by screwing the bolt 9 into the nut 5 after the beam 13 is supported on the upper plate 3a by fitting the positioning hole 13a of the boss 7 into the boss 7.

In the above embodiment, the floor member 4
Has a structure in which a panel supporting member 14 is stretched over a beam 13 and a floor panel 15 is supported by the panel supporting member 14. However, as shown in FIG. It is possible to apply. In this example,
The pedestal portion 8 is formed in a flat plate shape, and the four corner back surfaces of the floor panel 15 are directly supported on the pedestal portion 8.

The floor panel 15 has a receiving portion 8
The fixing member 9 for fixing on the top has a screw 9a and a head 9b through which the screw 9a is inserted. The floor panel 15 is fixed by pressing it against the step 15a of the panel 15.

[0014]

As is apparent from the above description, according to the double floor supporting apparatus of the present invention, the positioning portion and the fixing member receiving portion are integrally formed on the floor receiving member for supporting the floor member. These positional relationships are always kept constant, and it is possible to improve the assembly accuracy of the floor member.
