Description

The present invention relates to a support structure for a partition wall provided on a double floor in which an upper floor is constructed on a lower floor such as a concrete slab.

Conventionally, a double floor is known in which a floor support is disposed on a lower floor such as a concrete slab, and an upper floor panel such as a particle board is stuck thereon (see Patent Documents 1 to 5).

  4 is a schematic plan view of the partition wall on the double floor, and FIG. 5 is a cross-sectional view taken along the line AA in FIG. 4, illustrating the structure of the conventional partition wall on the double floor.

  In FIG. 4, the partition wall 1 is provided on a double floor, and the upper side of the figure is the A room and the lower side is the B room.

  In FIG. 5, the double floors in rooms A and B have floor supports 2 and 3 appropriately disposed on a lower floor 17 such as reinforced concrete, and an upper floor base panel 15 such as a particle board is stuck thereon. Further, an arbitrary finishing material 16 such as a florin material is attached thereon. In the lower part of the partition wall 1, the floor support 2 is arranged on the lower floor 17 along the length of the wall, and the floor support 2 supports the ends of the upper floor base panels 15 of the A and B rooms on both sides. is doing.

  In this case, the partition wall 1 is obtained by attaching wall materials 13 (plaster board, veneer plywood, etc.) to both sides of a shaft assembly 12 made of wood, and a baseboard 14 is provided at the lower part. The partition wall 1 is assembled on the upper floor base panel 15.

  The conventional partition wall structure on the double floor is simpler in construction and advantageous in terms of construction period and cost than the structure in which the partition wall is erected from the lower floor, but the noise and vibration generated on the upper floor are the upper floor base panel. The noise is transmitted directly from the partition wall to the partition wall, and further from the partition wall to the adjacent room (see the waveform in FIG. 5). An object of the present invention is to solve this problem and to develop a partition wall support structure on a double floor which is excellent in noise prevention effect.

In the present invention, a wall support is disposed on the lower floor along the length direction of the partition wall, a base panel is provided along the length of the wall at the center of the wall support, and the partition is formed on the base panel. erected wall, the wall support at both ends on both sides of the double top floor base panel of the floor of the room the partition wall is supported by the wall support structure in which a buffer material between said base panel and said upper floor base panel The wall support includes a floor support having a bolt, an elastic leg attached to the lower part of the bolt, and a support plate attached to the upper part of the bolt so that the height can be adjusted, and the support plate. It is a joist disposed on the upper surface of the partition wall in the length direction of the partition wall, and the two joists are disposed in parallel with the bolt interposed therebetween. .

  In the present invention, the double floor of the room on both sides of the partition wall means that the upper floor is formed with a space on the lower floor, and the floor support that supports the upper floor floats the upper floor from the lower floor. It can be anything that can be supported. FIG. 2 shows an example of a single foot support 2, which is composed of a support plate portion 5, a receiving bracket 7, a bolt 6 and a leg portion 8. The support plate portion 5 is a wooden plate having a bolt hole, and a receiving bracket 7 is fixed to the lower surface. A bolt 6 is screwed into the female screw hole of the receiving bracket 7. The leg 8 is an anti-vibration rubber with the lower end of the bolt 6 inserted. There is a diametrical groove on the upper surface of the bolt 6, and the height can be adjusted by rotating with a screwdriver from above. FIG. 3 shows a multi-legged floor support 3, in which members having the same functions as those in FIG. As the floor support, various types such as a single foot floor support of FIG. 2, a multi-leg floor support of FIG. 2 and 3 show a plan view at the top and a cross-sectional view at the bottom.

  The partition wall is erected on the pace panel separated from the upper floor base panel on both sides of the room, and the cushioning material is provided between the upper floor base panel and the pace panel. Is difficult to be transmitted to the partition wall and the other room, and the noise prevention effect is improved.

  In the present invention, the floor support includes a wall support having a bolt, a leg portion made of an elastic body attached to the lower portion of the bolt, and a support plate portion attached to the upper portion of the bolt so that the height can be adjusted. It is desirable that the upper surface is composed of joists disposed in the length direction of the partition wall. Here, as the floor support, for example, the floor supports 2 and 3 of FIGS. 2 and 3 can be used. Such a floor support is easy to construct because it prevents the vibration from being transmitted to the lower floor by the legs of the elastic body and can easily adjust the height. For example, long wood can be used as the joist. The joist is preferably provided over the entire length of the wall.

  It is desirable that two joists be arranged in parallel across the bolts of the floor support. By separating the joists from left and right, it is possible to reduce the vibration and noise of the upper floor of one room from being transmitted to the other room through the joists. In addition, the height can be easily adjusted by rotating the bolt through the gap between the two joists.

  The upper floor base panel only needs to be a structural material (that receives the load on the upper floor and transmits it to the floor support), and is generally a particle board or plywood.

  The base panel at the lower part of the partition wall is preferably made of the same material and the same thickness as the upper floor base panel, but is not limited thereto.

  The cushioning material may be a soft material that is difficult to transmit vibration and noise, such as caulking material, foamed material such as sponge, and rubber.

  FIG. 1 is an explanatory cross-sectional view of a partition wall support structure on a double floor according to an embodiment. In the A room and the B room, the upper floor base panel 15 is stuck on the floor support 3 arranged on the lower floor 17 at an appropriate interval, and the finishing material 16 (flooring panel) is further stuck thereon. A finishing material different from the A room and the B room, for example, one may be a flooring panel and the other may be discarded and carpeted on the veneer. The partition wall 1 is made by sticking wall materials 13 on both sides of a shaft assembly 12 made of wood and providing a baseboard 14 on the lower part, and a wall support 9 along the length direction of the wall 1 on the lower floor 17. The base panel 11 is provided in the center of the wall support 9 along the length direction of the wall 1, and the partition wall 1 is erected thereon.

  The wall support 9 includes a single leg floor support 2 disposed on the lower floor 17 at appropriate intervals, and two joists 10 disposed on the floor support 2 in parallel with bolts 6 of the floor support 2 interposed therebetween. . The floor support 2 is shown in FIG. 2, and includes a bolt 6 and a leg portion 8 made of an elastic body attached to the lower portion of the bolt 6 and a support plate portion 5 attached to the upper portion of the bolt 6 so that the height can be adjusted. It is possible to easily adjust the height by rotating the bolt 6 with a screwdriver between the two joists 10. The floor support is not limited to a single foot and may be a multiple foot. The wall support 9 supports the partition wall 1 and supports the ends of the upper floor base panel 15 of the double floor of the rooms (room A and room B) on both sides of the partition wall 1 at both ends. A cushioning material 4 is provided between the base panel 11 and the upper floor base panel 15.

  The present invention is effective when applied to a partition wall of a double floor such as an apartment building or an office building. The lower floor is mainly a concrete slab, but is not limited to this.
