By pressing the tube container 62 with the discharge port of the tube container 62 located in each gap between the plurality of wires 50, the POS seal 64 is discharged to a position desired by the user. As a result, the POS seals 64 are evenly filled in the gaps between the wirings 50 . If there is a gap between the glass wool 60 and the hole 14 and the insertion hole 12, the gap may be filled with the POS seal 64.

After the wiring routing work and the airtight processing work are performed as described above, the upper side member 32 is attached to the frame 20, and the partition wall 10 is installed.

In the partition wall structure of the first embodiment, the following excellent effects can be obtained as compared with the prior art. Here, the conventional technology will be described. FIG. 4 is a top side sectional view of a conventional partition wall. In the conventional partition wall structure, as shown in FIG. 4, wood 72 for fixing the airtight material 70 is installed on the back surface (upper surface) of the ceiling CL. The wood 72 has a hole 72A in the center through which a plurality of wirings 50 are inserted, and an airtight material 70 is filled between the inner peripheral surface of this hole 72A and the plurality of wirings 50. As shown in FIG. EPDM (ethylene propylene rubber), which is a foamed rubber material, has been used as the airtight material 70 . In order to fill the airtight material 70, it was necessary to insert a hand through the inspection opening A provided near the partition wall of the ceiling CL, and the work was difficult.

On the other hand, the partition wall structure of the first embodiment is positioned below the upper horizontal beam 24 in the vertical direction and has a space S communicating with the insertion hole 12 in the wall. As a result, in the space S with the upper side surface member 32 removed, it is possible to easily carry out the work of wiring the wiring 50 extending from the ceiling space to the distribution board 40 and the airtightness processing work of closing the gap into which the gas flows. can. Therefore, workability can be improved. Furthermore, since work can be performed in the space S, there is no need to provide an inspection opening A in the ceiling CL.

Further, the partition wall structure of the first embodiment includes a third intermediate horizontal beam 28C positioned below the upper horizontal beam 24 in the vertical direction and supporting the lower end of the upper side surface member 32. As shown in FIG. Therefore, after the work is completed, the upper side member 32 can be attached by fixing the upper side member 32 to the third intermediate horizontal beam 28C.

In addition, in the partition wall structure of the first embodiment, the third intermediate horizontal beam 28C further supports the upper end portion of the lower side member 34 . As a result, the third intermediate cross member 28C supports the lower end of the upper side member 32 and the upper end of the lower side member 34, so that the single third intermediate cross member 28C supports the upper side member 32 and the lower side member 34. can be fixed. Therefore, the number of crosspieces can be reduced, and the number of parts can be reduced.

In addition, in the partition wall structure of the first embodiment, the lower side member 34 extends from the ceiling space and has a mounting opening 34A for mounting the distribution board 40 connecting the plurality of wires 50 passing through the insertion holes 12 .

Moreover, the partition wall structure of the first embodiment includes glass wool 60 filled between the inner peripheral surface of the insertion hole 12 and a plurality of wirings extending from the ceiling space. As a result, the space between the inner peripheral surface of the insertion hole 12 and the plurality of wires 50 extending from the ceiling space is filled with the glass wool 60, so that the gap existing between the inner peripheral surface of the insertion hole 12 and the wires 50 is released. can be prevented from entering the room. Thereby, airtightness can be improved.

Moreover, the partition wall structure of the first embodiment includes POS seals 64 that fill the gaps between the plurality of wirings 50 . Therefore, the gaps between the wirings 50 are filled with the POS seal 64, so that the gas can be prevented from flowing into the room through the gaps between the wirings. This can further improve airtightness.

Moreover, in recent years, the number of wires 50 has increased due to the existence of a wide variety of devices. Therefore, the opening areas of the insertion hole 12 and the hole portion 14 become large, and the larger the opening area, the higher the cost required for the material to be filled in the gap. Therefore, when the glass wool 60 and the POS seal 64 are used as in the first embodiment, the airtightness is substantially the same as when EPDM is used, but the cost can be reduced.

In addition, in the partition wall 10 of the first embodiment, before the front surface member 30B is attached to the frame 20, the space existing between the crosspieces may be filled with a sound insulating material, a heat insulating material, or the like.
