Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for preventing sound and light from leaking through an end portion of a partition panel and a bracket locking hole formed in a column supporting the end portion of the partition panel. The present invention relates to a light shielding / sound insulation device for preventing noise.

[0002]

SUMMARY OF THE INVENTION The present applicant has previously disclosed in Japanese Utility Model Laid-Open Publication No. 3-48013 a vertically elongated U-shaped vertical frame member for connecting the vertical side edges of a partition panel. As a device for preventing light from leaking from a locking groove hole for a bracket or the like perforated up and down at an appropriate interval on both front and back side plate portions, the end side plate portion of the vertical frame member has It was proposed to provide a partition that extends the space in the direction that bisects the thickness of the partition panel.

However, in the device of the prior art, sound leakage cannot be prevented because the length of the partition piece is insufficient. Further, even if the end of the partition piece is extended so as to be in contact with the end of the panel core material, it is difficult to completely stop sound leakage because the thickness of the partition piece is small. Further, if the panel core material is not inserted, the sound insulation cannot be achieved.

[0004] On the other hand, when locking slots for brackets and the like are vertically formed at appropriate intervals on both front and back plate portions of a column having a hollow rectangular cross section for supporting the ends of the partition panel, the brackets may be used. As a device for preventing light or sound from leaking to the opposite side through a locking slot at an unlocked portion, there is Japanese Utility Model Laid-Open No. 3-23524, which has a complicated structure and a large number of parts. There was a problem.

It is an object of the present invention to provide an apparatus which solves these problems.

[0006]

In order to achieve the above-mentioned object, the present invention provides a vertically long U-shaped vertical frame member for connecting the vertical side edges of the partition panel or an end of the partition panel. On the front and back sides of the hollow column, locking slots for brackets etc. are drilled up and down at appropriate intervals,
Inside the vertical frame member or the support, a partition portion that partitions the internal space of those members in parallel with the front and back side plate portions and a direction extending substantially perpendicular to the partition portion extends in a direction intersecting at right angles, and the vertical frame member or A vertically long insertion member including a pair of sound insulation pieces that abut on the inner surfaces of the front and back side plate portions of the support is detachably disposed.

[0007]

With such a configuration, the internal space of the vertical frame member or the hollow column in the partition panel projects from the partition portion of the interposition member inserted into the internal space and the partition portion. With the pair of sound insulation pieces, the space between the locking grooves on both the front and back sides of the vertical frame member or the support is cut off, and light or sound entering from one locking groove can be blocked by the other locking groove. Leakage can be completely prevented. And since the insertion member is an integrally molded product, the configuration is extremely simple, and the effect of being inexpensive is achieved.

[0008]

Next, an embodiment of the present invention will be described. FIGS. 1 and 2 show a first embodiment. As will be described later, a vertically long U-shaped vertical frame member 6 for connecting the vertical side edges of the partition panel 2 is provided with a light shielding / sound insulating device. Things. Reference numeral 1 denotes a pillar having a rectangular cross section in a hollow section in the partition, and reference numeral 2 denotes a partition panel attached to a side portion of the pillar 1 with an engaging metal fitting (not shown). The partition panel 2 is a honeycomb-shaped panel made of a synthetic resin thin plate or the like. It comprises a core member 3, front and back double-sided plates 4, 5, and a vertical frame member 6 having a U-shaped cross section that connects between vertical side edges of the front and back double-sided plates 4,5. The panel core member 3 and the front and back double-sided plates 4 and 5 are adhered and fixed with an adhesive, and the front and back side plate portions 6a and 6b of the vertical frame member 6 and the front and back double-sided plates 4 and 5 are attached.
5 may be adhered and fixed with an adhesive, or may be fixed by spot welding when metal is used. The front and back side plate portions 6a and 6b of the shelf frame member 6 are provided with rectangular locking grooves 9 for locking the locking claws 8 projecting rearward from the base of the bracket 7 at regular intervals. It is set up.

Reference numeral 10 denotes a shelf-length insertion member according to the present invention, which is an extruded member made of synthetic resin. Interposition member 10
As shown in the figure, a partitioning portion 1 for partitioning the internal space of the shelf frame member 6 in a substantially parallel manner substantially at the center of the front and back side plate portions 6a and 6b.
1 and the partitioning portion 11, and extends in a direction substantially perpendicular to the partitioning portion 11, and comes into contact with the end plate portion 6 c of the vertical frame member 6 and the end portion of the panel core material 3 or the inner surfaces of the front and back double-sided plates 4 and 5. It has a substantially H-shaped cross section including a pair of sound insulation pieces 12 and 13.

[0010] Of the pair of sound insulation pieces, one of the sound insulation pieces 12 is brought into close contact with the inner surface of the end plate portion 6c via an adhesive or a double-sided adhesive tape, and the other sound insulation piece 13 is a pair of free ends. The vertical frames are integrally formed so that the portions 13a, 13a are soft resin portions, and the free ends 13a, 13a are slightly bent so that the free ends 13a, 13a are in close contact with the inner surfaces of the front and back double-sided plates 4, 5 (stretching adherence). It is inserted into the member 6.

According to this configuration, the partition 11 of the insertion member 10 and the pair of sound insulation pieces 12 and 13 can completely block the internal space of the vertical frame member 6 into two, so that one of the locking slots 9 is formed.
Sound and light coming from the outside are blocked, and can be prevented from leaking into the other locking slot 9. In addition, even when the partition panel 2 does not have the panel core material 3, the effect remains unchanged. Reference numerals 14 and 15 denote two vertically extending two-piece vibration-preventing pieces protruding from both side surfaces of the partitioning portion 11.
Reference numeral 15 denotes a locking claw that is engaged with the locking groove and is disposed at a position sandwiching the left and right sides of the locking claw 8 facing the vertical frame member 6. 8 can be prevented, and thus the tip of the bracket 7 can be prevented from largely swinging.

FIG. 3 shows a second embodiment applied to a column.
The column 16 has a U-shaped cross section, and the side edge 18a of the partition panel 18 is fitted in the opening groove 17 side.
A locking groove 9 similar to that described above is formed in the front and back side plate portions 16a and 16b. The structure of the synthetic resin insertion member 10 is the same as that described above for the partition portion 11 and the end plate portion of the support column 16. 16c
A sound insulating piece 12 that abuts (adhesively fixes) on the inner surface, a sound insulating piece 13 of a soft synthetic resin portion that abuts on the outer surface of the side edge 18 a of the partition panel 18, and a pair of vibration-reducing pieces 14, 15 protruding from the partition 11. Consists of In the case of this embodiment as well,
It goes without saying that the same operation and effect as those of the embodiment can be obtained.
