Definitions

  • the present invention relates to a partition wall which forms the boundary between rooms in concrete buildings such as multistoried buildings, buildings, schools, hotels, hospitals, and the like and more particularly, to a partition wall which is easily installed on rooms in concrete buildings and superior in sound insulation and fire resistance.
  • partition wall which forms the boundary between rooms in concrete buildings such as multistoried buildings, buildings, schools, holtels, hospitals, and the like are superior in sound insulation and fire resistance.
  • the partition wall according to the disclosure comprises two internal partition boards 51, 51; external partition boards 52, 52 and gypsum bond 55.
  • the internal partition boards 51, 51 are formed by connecting the end faces of a plurality of gypsum boards disposed in contact with and along steel runners fixed to ceiling and floor walls. A certain interval is provided between the two internal partition boards 51, 51.
  • Gypsum external partition boards 52, 52 are installed in the exteriors of the internal partition boards 51, 51 with a certain interval provided from the internal partition boards 51, 51.
  • an internal closed space 53 is formed between the internal partition boards 51, 51.
  • the external and internal partition boards 51, 2 are connected by the gypsum bond 55.
  • external closed spaces 54, 54 are formed between the respective internal partition boards 51 and external partition boards 52, i.e., three closed spaces 53, 54, 54 are formed inside the fire-resistant partition wall.
  • the fire-resistant partition wall comprises the internal and external partition boards connected to each other by the gypsum bond 55, the internal and external partition boards 51, 52 must be thick so that the partition wall may be rigid. Accordingly, such a partition wall is heavy and the spaces of rooms where the partition wall is installed are reduced by thickness of the partition wall. Further, since the internal partition board is connected to the external partition board by gypsum bond, heat is transferred from the external partition board to the internal partition board to a small extent. As such, when a fire breaks out, the external partition wall disposed nearer to the fire than the internal partition board is overheated in a short period of time and consequently, burnt down.
  • a partition wall according to the present invention comprises gypsum internal partition boards with a certain interval provided therebetween; gypsum external partition boards with a certain interval provided from the respective internal partition boards; and three closed spaces provided inside the partition wall; the partition wall being characterized in that an internal partition boards-connected portion disposed on one side of the partition wall does not coincide with an external partition boards-connected portion disposed on the side opposite to the above-described portion; and a gypsum reinforcing board is adhered to the external face of the internal partition boards-connected portion by an adhesive, and the external partition boards are adhered to the external face of the reinforcing board by an adhesive in such a manner that an external partition boards-­connected portion is disposed between both ends of the reinforcing board.
  • the partition wall having the above-described construction is very rigid although it is composed of thin gypsum boards. Further, the partition wall is superior in fire resistance and sound insulation. Furthermore, since the respective partition boards are composed by only adhering gypsum boards by an adhesive, it is manufactured easily and no skille workmanship is necessary in installing it on a rom and it is installed with efficiency.
  • numeral 1 denotes a ceiling wall of a building; 2, floor wall of the building; 3, channel-shaped runners fixed to walls, namely, the ceiling wall 1 and floor wall 2. Blades of the upper runner 3 confront the blades of the lower runner 3.
  • internal partition boards 4, 4 Fixed to the blades of the upper and lower runners 3, 3 are internal partition boards 4, 4 formed by connecting a plurality of gypsum boards as shown in Fig. 2.
  • the thickness of an internal closed space 5 formed between the internal partition boards 4, 4 equals to the width of the runner 3.
  • a sound insulation material (C) such as glass wool is filled in the internal closed space 5.
  • the position of an internal partition boards-connected portion 6 coincides substantially with the middle of the internal partition board 4 which confronts the portion 6.
  • a gypsum reinforcing board 7 which serves as a spacer and is half the length of the internal partition board 4 is adhered to the internal partition boards-connected portion 6 by an adhesive 8 consisting of vinyl acetate. Accordingly, as shown in Fig. 2, the reinforcing boards are staggered in a plan view.
  • External partition boards 9 whose lengths are same as that of the internal partition board 4 is adhered to the external face of the reinforcing board 7 by the adhesive 8 consisting of vinyl acetate in such a manner that an external partition boards-­connected portion 10 is dosposed at substantially the middle of the reinforcing board 7.
  • the position of the internal partition boards-connected portion 6 does not coincide with the position of the external partition boards-connected portion 10 as shown for example in Fig. 2.
  • an external closed space 11 whose length is same as that of the reinforcing board 7 is formed between the internal partition board 4 and the external partition board 9, thus the external closed space 11 being staggered in a plane view as shown for example in Fig. 2.
  • a space where the reinforcing board 7 is provided between the internal and external partition boards 4, 9, namely, a space which confronts a space where the external closed space is provided between the internal and external partition boards 4, 9 consists of three gypsum boards adhered to each other. Accordingly, the partition wall is rigid and further, sound does not leak therefrom when the partition wall is vibrated. Furthermore, since the internal partition board 4 is connected to the external partition board 9 by the reinforcing board 7 which is half the length of the internal and external partition boards 4, 9, heat is favorably transferred from the external board 9 to the internal partition board 4, so that the partition wall is not locally overheated, that is, the partition wall is not burnt down in a short period of time.
  • a gypsum bond is at a certain interval provided between the end face of the reinforcing board 7 and the external face of the internal partition board 4 so as to reliably adhere the reinforcing board 7 to the internal partition board 4 and increase the heat insulation performance of the partition wall.
  • the cross-linking of sound can be effectively prevented by providing the gypsum bond in such a manner that the gypsum bond 12 does not contact or contacts with the external partition board 9 to a slight extent.
  • a partition wall as shown in Fig. 5 can be used at a place where only sound insulation performance is considered. Unlike the first embodiment according to the present invention, no gypsum bond is provided between the external face of the internal partition board 4 and the end faces of the reinforcing board 7. The sound insulation value obtained by the partition wall having this construction was over D-45.,
  • a partition wall as shown in Fig. 6 an angle was used as a steel runner and a spacer composed of gypsum board is disposed at the upper and lower ends between the internal partition boards 4, 4 so as to form an internal closed space therebetween.
  • the length of the reinforcing board 7 is 1/4 of the gypsum board which composes internal and external partition boards.
  • the partition wall was subjected to heating for an hour (highest temperature the partition wall was subjected to was 935°C). The sound insulation value obtained was over D-35.
