Description

[Detailed explanation of the idea] This invention relates to a floor device.

As shown in FIG. 1, in the conventional steel-framed floor system, a large support bracket 2a of a large support fitting 2 attached to the side surface of a floor beam 1 supports a large support 3, and a large support clamp 2b supports the main support 3. The main drawer 3 is clamped and fixed to the main support fitting 2 with iron round nails 4.

However, with such a structure, there was a problem in that the shock and vibration applied to the main drawer 3 were transmitted to the floor beam 1 via the large support fitting 2, and a squeak was generated between the main drawer 3 and the large support fitting 2. .

Therefore, an object of this invention is to provide a floor device that can absorb shocks and vibrations applied to the floor puller and prevent the generation of squeaks between the floor puller and the floor support fitting.

An embodiment of this invention is shown in FIG.

That is, this floor device has a large underwriting base portion 5 of the large underwriting fitting 3.
At the same time as placing the anti-vibration rubber 6 on the large holding part 5b, a vertically elongated hole 5C for inserting a bolt is placed on the large holding part 5a. The bolt 7 is inserted into the through hole 3a of the drawer 3 through the vertical bolt insertion hole 5C of the drawer holding portion 5b, and the nut 8 is tightened.

As a result of this configuration, shocks and vibrations applied to the pull-out are absorbed by the vibration isolating rubber 6, and squeaks are no longer generated.

In addition, at this time, as the main puller 3 moves up and down, the bolt 7
moves up and down within the vertically elongated bolt insertion hole 5C.

Another embodiment of this invention is shown in FIG.

In this embodiment, extension parts 6a are provided at both ends of the vibration isolating rubber 6 and extend along the large tension holding part 5b, and the extension parts 6a are interposed between the large tension holding part 5b and a large tension part (not shown). This also prevents squeaks between the outer puller and the outer puller holding portion 5b.

Other configurations and effects are the same as those in FIG. 2.

As described above, in the floor device of this invention, a vibration isolating material is placed on the large undertaking part of the large underwriting fitting, and a vertical hole for bolt insertion is provided in the large holding part. The daihiki is placed on top of the vibration isolator, and the bolt is inserted into the through hole of the daihiki through the vertical bolt insertion hole in the daihiki clamping part, and then tightened with a nut, so it takes part in the daihiki. It can absorb shock and vibration, and has the effect of preventing the generation of squeaks between the main drawer and the main support fitting.
