DETAILED DESCRIPTION OF THE INVENTION

[0007] Embodiment 1 As shown in FIG. 1, a building 1 according to a first embodiment of the present invention comprises a beam 2 made of a wooden material and a wall 3 provided below the beam 2, and the beam 2 is made up of a plurality of wooden beam members 20, ... arranged at a predetermined interval G along the beam width direction X of the beam 2.

[0008] In the building 1 according to the first embodiment, the beams 2 are configured to support the load of structures such as a slab (upper floor slab) 10 located on the beams 2 . That is, the beam 2 is, for example, composed of two beam members 20, 20, which are formed by dividing a beam made of wooden material along the beam width direction of the beam so that it has the beam width and beam configuration necessary to support the load of the building, and the two divided wooden beam members 20, 20 are arranged at a predetermined distance G along the beam width direction X of the beam 2.

[0009] In other words, the beam 2 is a beam configured to include one beam material 20 and the other beam material 20 arranged at a predetermined interval G along the beam width direction X of the beam 2, and a space (air layer) formed by the predetermined interval G. The predetermined interval G may be, for example, about several mm to several tens of mm. Furthermore, the beam material 20 may be formed from a wood material such as CLT (Cross Laminated Timber), laminated timber, LVL (Laminated Veneer Lumber), or solid wood. Furthermore, the beam 20 is joined, for example, at the beam end (both ends of the beam) of the beam 20 to a column not shown in the figure by a column-beam joining means such as a gusset plate or metal fittings not shown in the figure, and is joined to the slab (upper floor slab) 10 via a slab-beam joining means such as a joining stud not shown that is arranged to protrude from the top surface of the beam 20.

[0010] The wall 3 is constructed with a wall base 30 and a wall finishing material not shown. The wall base 30 is composed of studs 31, support material 32 fixed to the slab (floor slab) 10 to receive the lower ends of the studs 31, a stud lower end fixing means (not shown) for fixing the lower ends of the studs 31 to the support material 32, a stud upper end fixing means (not shown) for fixing the upper ends of the studs 31 to the lower ends of the beams 2, base boards 33 attached to the sides (sides in the beam width direction) of the studs 31 and the beams 2 to form the wall base surface, and insulation material 34 installed between the base boards 33 (the base board 33 forming one wall base surface 31a) and the base board 33 (the base board 33 forming the other wall base surface 31b) that face each other at a predetermined distance in the wall thickness direction.

[0011] The base board 33 is, for example, a surface material such as gypsum board. The studs 31 are base materials for attaching the base boards 33, and are, for example, long wooden members with a rectangular cross section. The support member 32 is a member fixed to the slab (floor slab) 10 to fix the lower ends of the studs 31, and is, for example, a wooden member. The stud lower end fixing means and the stud upper end fixing means are fixing means such as metal fittings, nails, screws, etc. not shown in the figure, and the lower end of the stud 31 is fixed to the support material 32 by the stud lower end fixing means, and the upper end of the stud 31 is fixed to the underside of the beam material 20 by the stud upper end fixing means. The heat insulating material 34 is, for example, rock wool, glass wool, or the like. The wall finishing material is, for example, wallpaper, paint, etc.

[0012] Furthermore, the wall 3 is provided with a plurality of studs 31, 31... that form one wall base surface 31a and a plurality of studs 31, 31... that form the other wall base surface 31b, and the plurality of studs 31, 31... that form one wall base surface 31a and the plurality of studs 31, 31... that form the other wall base surface 31b are arranged at a distance from each other and do not come into contact with each other (disconnected edges), thereby resulting in a wall with improved sound insulation performance.

[0013] For example, as shown in Figure 1(b), the wall 3 has a wall base 30 configured by a plurality of studs 31, 31... forming one wall base surface 31a and a plurality of studs 31, 31... forming the other wall base surface 31b, which are arranged in a staggered pattern along the horizontal direction (the up-and-down direction in Figure 1(b)). Furthermore, for example, as shown in Figure 1(b), the wall base 30 is configured so that the base boards 33 attached to the multiple studs 31, 31... that make up one wall base surface 31a are spaced apart from the multiple studs 31, 31... that make up the other wall base surface 31b, and so that the base boards 33 attached to the multiple studs 31, 31... that make up the other wall base surface 31b are spaced apart from the multiple studs 31, 31... that make up one wall base surface 31a. Also, for example, the heat insulating material 34 is installed sandwiched between a plurality of studs 31, 31... forming one wall base surface 31a and a plurality of studs 31, 31... forming the other wall base surface 31b. In other words, the wall 3 is configured to be a wall (a wall with excellent sound insulation performance) in which sound transmitted to one wall surface (for example, a wall surface formed by the surface of the base board 33 attached to the plurality of studs 31, 31... that make up one wall base surface 31a) is less likely to be transmitted to the other wall surface (for example, a wall surface formed by the surface of the base board 33 attached to the plurality of studs 31, 31... that make up the other wall base surface 31b). In addition, FIG. 1 illustrates a configuration in which the wall surface of the wall 3 is formed as a two-layer wall surface in which two base plates 33 are stacked.

[0014] In addition, in the building 1 of embodiment 1, one wall base surface 31a and the side surface of one beam 20 are located on the same vertical plane, and the other wall base surface 31b and the side surface of the other beam 20 are located on the same vertical plane. Furthermore, by attaching the base board 33 across one wall base surface 31a and the side of one beam 20, one wall surface formed on the outside of one wall base surface 31a and the outside of the side of one beam 20 is configured to be positioned on the same vertical plane, and by attaching the base board 33 across the other wall base surface 31b and the side of the other beam 20, the other wall surface formed on the outside of the other wall base surface 31b and the outside of the side of the other beam 20 is configured to be positioned on the same vertical plane. That is, a fire-resistant beam 2 is formed in which the side surface of one beam 20 and the side surface of the other beam 20 are covered with the base board 33. Furthermore, since one wall surface is positioned on the same vertical plane and the other wall surface is positioned on the same vertical plane, it is possible to form a wall surface without any irregularities, thereby making it possible to make the interior space larger.

[0015] According to the building 1 of embodiment 1, the beam 2 is configured to include one beam material 20 and the other beam material 20 arranged at a predetermined interval G along the beam width direction X of the beam 2, and the edges between the one beam material 20 and the other beam material 20 constituting the beam 2 are configured to be disconnected, so that solid propagation of sound S can be suppressed, sound insulation performance is improved, and a building 1 can be provided with a beam 2 having excellent sound insulation performance. Furthermore, the wall 30 is configured so that the multiple studs 31, 31... that form one wall base surface 31a and the multiple studs 31, 31... that form the other wall base surface 31b are spaced apart and do not come into contact with each other (disconnected edges), making it possible to provide a building 1 that has a wall 30 with excellent sound insulation performance underneath a beam 2 with excellent sound insulation performance.

[0016] Embodiment 2 As shown in Figure 2, in a building 1 according to embodiment 2 of the present invention, one or more studs 31A among the multiple studs that make up the wall base surface of a wall 3 are load-bearing columns that support the load of a beam 2. That is, the wall 3 of the building 1 in embodiment 2 is configured to have a wall base 30A in which, instead of one or more of the multiple studs 31, 31... that constitute the wall base 30 of the wall 3 of the building 1 in embodiment 1, a stud 31A that functions as a load-bearing column is provided. Stud 31A, which functions as a column load supporting column, is made of, for example, a long wooden member with a square cross section that has a larger cross-sectional area than stud 31.

[0017] In addition, in Figure 2 showing the contents of embodiment 2, the same symbols as those used in Figure 1 showing the contents of embodiment 1 are used, and parts for which no special explanation has been added are the same as the parts explained in embodiment 1, so explanations of those parts will be omitted.

[0018] That is, the building 1 of embodiment 2, like embodiment 1, comprises a beam 2 and a wall 3 arranged below the beam 2, and the beam 2 is composed of a plurality of wooden beam materials 20, 20 arranged at a predetermined interval G along the beam width direction W of the beam 2. The wall 3 is configured to include a wall base 30A using studs 31A that function as column load support columns. Furthermore, as in embodiment 1, the wall 3 is configured such that the multiple studs 31, 31, 31A... that form one wall base surface 31a and the multiple studs 31, 31, 31A... that form the other wall base surface are spaced apart and do not come into contact with each other (the edges are disconnected), thereby improving the sound insulation performance of the wall.

[0019] According to the building 1 of embodiment 2, one or more of the multiple studs that make up the wall base surface of the wall 3 are configured to be load-supporting columns that support the load of the beam 2, making it possible to keep the cross-sectional area of ​​the beam 2 small.

[0020] Embodiment 3 As shown in Figure 3, the building 1 of embodiment 3 is configured with a panel 33A that functions as an earthquake-resistant reinforcement material attached across the side of the beam material 20 that forms the side of the beam 2 and the side of the studs 31, 31, 31A... of the wall 30. The face material 33A may be, for example, structural plywood.

[0021] In addition, in Figure 3 showing the contents of embodiment 3, the same symbols as those used in Figure 2 showing the contents of embodiment 2 are used, and parts for which no special explanation has been added are the same as the parts explained in embodiment 2, so explanations of those parts will be omitted.

[0022] That is, the building 1 of embodiment 3, like embodiment 2, comprises a beam 2 and a wall 3 arranged below the beam 2, and the beam 2 is composed of a plurality of wooden beam materials 20, 20 arranged at a predetermined interval G along the beam width direction X of the beam 2. The wall base 30B of the wall 3 is configured to include, as in embodiment 2, studs 31A that function as column load-supporting columns, and also includes surface materials 33A that function as earthquake-resistant reinforcement materials attached across the side surfaces of the beam material 20 that forms the side surface of the beam 2 and the side surfaces of the studs 31, 31, 31A... of the wall 30. In the wall base 30B of the building 1 according to the third embodiment, a base board 33 is attached to the outside of a surface material 33A to form a wall surface. Furthermore, as in embodiment 2, the wall 3 is configured such that the multiple studs 31, 31, 31A... that form one wall base surface 31a and the multiple studs 31, 31, 31A... that form the other wall base surface are spaced apart and do not come into contact with each other (the edges are disconnected), thereby improving the sound insulation performance of the wall.

[0023] According to the building 1 of embodiment 3, the same effects as those of the building 1 of embodiment 1 and embodiment 2 can be obtained, and since the wall 30 can be configured as a load-bearing wall (earthquake-resistant wall), it is possible to provide a building 1 with excellent earthquake resistance.

[0024] In the buildings according to the above-described embodiments, the beam 2 is exemplified as being configured by two wooden beams 20, 20 made of wood material, arranged at a predetermined interval G along the beam width direction X of the beam 2, but the beam may also be configured by three or more wooden beams 20, 20, 20, ... made of wood material, each arranged at a predetermined interval G along the beam width direction X of the beam.

[0025] Furthermore, in the building 1 according to the above-mentioned embodiments 1, 2 and 3 (see Figures 1 to 3), a wall base structure has been exemplified in which the lower ends of the studs 31 are fixed to the support material 32 by stud lower end fixing means and the upper ends of the studs 31 are fixed to the underside of the beam material 20 by stud upper end fixing means. However, for example, a configuration may also be adopted in which a lower runner (not shown) is fixed to the support material 32 or the slab (floor slab) 10 and an upper runner (not shown) is fixed to the underside of the beam material 20, and the lower ends of the studs 31 are fitted into the lower runner and the upper ends of the studs 31 are erected so that they are fitted into the upper runners of the beam material 20, and then a base board 33 is attached to the studs 31 erected in this manner with fastening materials such as screws. In this case, instead of the studs 31 formed from wooden members, studs made of lip channel steel (C-shaped steel) or the like may be erected between the upper and lower runners. That is, in the wall foundation structure of the present invention, it is not necessarily required to fix the studs to the beams 20 and the slab (floor slab) 10.

[0026] Furthermore, the building according to the present invention may be configured to include a beam 2 as described above and a wall with excellent sound insulation performance provided below the beam 2. For example, the building may be configured such that the beam 2 has a fire-resistant structure like the beam 200 shown in FIG. 4, and the wall is a wall 300 as shown in FIG. 4.

[0027] Furthermore, since the intended object of the present invention is to provide a building in which the sound insulation performance of beams made of wooden materials is improved, the building according to the present invention may be a building having a plurality of beams, at least one of which is made up of a plurality of wooden beams arranged at a predetermined interval along the beam width direction. Furthermore, the beam configuration of a building according to the present invention can be applied even when there is no wall below the beam. [Explanation of symbols]
