4. Operation and Effect of Partition Wall In the partition wall 1 of the present embodiment described above, the plurality of panel bodies P1 arranged in the left-right direction are such that two panel bodies P1 adjacent to each other on the left and right are formed with a ridge 510 and a concave ridge 520. Are connected in the up-down direction.

  Therefore, in the partition wall 1 of the present embodiment, a linear gap is not formed between the two panel bodies P1 adjacent to each other on the left and right sides, and a sound or a flame during a fire passes through the panel bodies P1 arranged on the left and right sides. Can be suppressed, and sound insulation and fire resistance can be improved.

  Further, in the partition wall 1 of the present embodiment, the gypsum board 6 covers joints between two panel bodies P1 adjacent to each other (specifically, joints between two metal outer skins 5 adjacent to each other). As a result, the arrival of the sound at the joint can be suppressed.

  Further, in the partition wall 1 of the present embodiment, since the main plate portion 50 of the metal outer skin 5 is adhered to the back surface of the lower gypsum board 4, the screws 11 driven into the upper gypsum board 6 from the front side to the main plate portion 50. Can be penetrated. Therefore, in the partition wall 1 of this embodiment, the upper gypsum board 6 can be firmly attached to the lower gypsum board 4.

  Further, in the partition wall 1 of the present embodiment, the plurality of panel bodies P1 arranged on the left and right can be firmly connected by the fitting of the convex ridge 510 and the concave ridge 520 of the metal outer skin 5, and The gypsum board 6 can be firmly attached to the plurality of panel bodies P1 with the screws 11. Therefore, in the partition wall 1 of the present embodiment, the strength of each of the pair of wall panels 2 can be easily secured, and the partition wall 1 can be formed by a non-stud method that does not require a stud between the pair of wall panels 2. .

  In addition, in the partition wall 1 of the present embodiment, since the partition wall 1 can be formed by the non-stud method, it is not necessary to fix each of the pair of wall panels 2 to the plurality of studs with the plurality of screws. Therefore, the workability is improved.

  Further, in the partition wall 1 of the present embodiment, since the gypsum board 6 can be attached with the screws 11, it can be constructed using an impact driver, which is a general tool, and can be used exclusively for a staple gun, a compressor, or the like. No tools are required. Therefore, the partition wall 1 of this embodiment is easy to construct.

  Further, in the partition wall 1 of the present embodiment, since the main plate portion 50 of the metal outer skin 5 is adhered to the entire back surface of the lower gypsum board 4, it is possible to freely select the driving position of the screw 11 of the upper gypsum board 6. The degree is high (that is, the screw 11 can be driven into an arbitrary position), and also in this point, the construction is easy.

  Further, in the partition wall 1 of the present embodiment, since the screw 11 for fixing the gypsum board 6 is not fixed to the connecting member 9, the vibration of the sound transmitted to the gypsum board 6 is transmitted through the screw 11. And transmission to the connecting member 9 can be prevented.

  Further, in the partition wall 1 of the present embodiment, since the coincidence frequencies of the gypsum boards 4 and 6 are different from each other, the sound insulation is higher than when two gypsum boards having the same coincidence frequency are arranged one on top of the other.

  Further, in the partition wall 1 of the present embodiment, since the vertical intermediate portions of the plurality of panel bodies P1 are fixed to the connecting members 9 with the screws 12, the panel bodies P1 are warped, and the ridges are formed. It is possible to suppress the occurrence of a problem in fitting the portion 510 and the concave ridge portion 520.

  Further, in the partition wall 1 of the present embodiment, the front and rear panel bodies P1 are connected via the connecting material 9, and each of the front and rear panel bodies P1 has an upper plaster harder than the lower plaster board 4 on each front side. The board 6 is fixed. For this reason, the partition wall 1 of the present embodiment easily secures the required rigidity as the wall surface.

  Moreover, in the partition wall 1 of this embodiment, the refractory packing 13 and the airtight packing 14 are sandwiched between two panel bodies P1 adjacent on the left and right (specifically, between two metal outer skins 5 adjacent on the left and right). . For this reason, in the partition wall 1 of the present embodiment, it is possible to more reliably prevent the sound and the flame at the time of fire from passing between the two panel bodies P1 adjacent to each other on the left and right.

  Further, in the partition wall 1 of the present embodiment, the upper plaster board 6 is not bonded to the lower plaster board 4 of the panel body P1 and is a separate member from the panel body P1. Therefore, the panel body P1 and the gypsum board 6 can be separately carried at the time of construction, and are easy to construct.

  The partition wall 1 of the present embodiment described above has, for example, a sound insulation performance of TLD50 (Transmission Loss Difference), and can be suitably used for a guest room of a hotel or the like.
