Fire-resistant and sound-insulating structure and method for manufacturing the same

Abstract

To provide a fireproof and sound-insulating structure capable of easily ensuring desired fireproof and sound-insulating properties using a single-sided partition wall in a situation where it is difficult to employ a double-sided partition wall.SOLUTION: A fireproof and sound-insulating structure 100 comprises: an inner column 7 as a structure constituting a part of a building 1; and a first wall portion 11 as a partition wall installed near the inner column 7. No other structure constituting a part of the building is provided near the first wall portion 11 in a space S on an opposite side to the inner column 7 side partitioned by the first wall portion 11. The first wall portion 11 includes: a base portion 11B forming an end of the partition wall on the inner column 7 side; and a face material 22 and a sound-insulating material 23 held by the base portion 11B at a position separated from the inner column 7 than a surface of the base portion 11B facing the inner column 7 side.SELECTED DRAWING: Figure 2

Claims

1. A structure that constitutes part of a building, The structure comprises a partition wall installed in the vicinity of the aforementioned structure, No other structures constituting part of the building are provided in the vicinity of the partition wall in the space opposite to the side of the structure that is partitioned by the partition wall. The partition wall comprises a base portion that forms the end of the partition wall on the structure side, and a facing material and a sound-insulating material held in the base portion at a position further away from the structure than the surface of the base portion facing the structure side. The partition wall further comprises an intermediate base portion adjacent to the surface of the facing material facing the structure, and another facing material held on the surface opposite to the surface of the intermediate base portion facing the structure, thus providing a fire-resistant and sound-insulating structure.

2. The fire-resistant and sound-insulating structure according to claim 1, wherein the partition wall is installed such that the distance from at least a part of it to the structure is less than 600 mm.

3. The aforementioned base portion has a plurality of studs that are installed in a line with intervals between them, The fire-resistant sound-insulating structure according to claim 1, wherein the sound-insulating material is arranged between both ends of the studs in the thickness direction of the partition wall.

4. The partition wall has a plurality of the aforementioned facing materials, each of which is a gypsum board. The fire-resistant and sound-insulating structure according to claim 1, wherein the plurality of the aforementioned facing materials are arranged in the thickness direction of the partition wall.

5. The fire-resistant and sound-insulating structure according to claim 1, wherein the structure is a column or a beam.

6. A method for creating a fire-resistant and sound-insulating structure that divides a space using partition walls installed near a structure that constitutes part of a building, A step of forming the base portion that forms the end of the partition wall on the structure side, The process of holding the facing material and sound insulation material in the aforementioned base portion from the side opposite to the structure side, A step of providing an intermediate base portion adjacent to the surface of the surface material that faces the structure, on the opposite side from the surface of the surface material that faces the structure, The process includes holding other facing materials on the surface opposite to the surface of the intermediate base portion that faces the structure, A method for manufacturing a fire-resistant soundproof structure, wherein the surface material and the sound-insulating material are placed at a position further away from the structure than the surface of the base portion facing the structure, and the partition wall is formed by the base portion, the surface material, the sound-insulating material, the intermediate base portion, and the other surface materials.
