Description

building wall

The present disclosure relates to building walls.

Conventionally, the method of constructing building walls such as partition walls and indoor walls of exterior walls by attaching architectural facing materials to studs (or studs) is to install studs that are erected at intervals in the horizontal direction. It is constructed by fastening a layered cladding consisting of an underlayment and a cladding made up of two pieces of architectural paneling.

More specifically, an underlay is formed by attaching multiple underlay materials to multiple studs with screws, etc., and multiple overlay materials are fastened to the underlay using staples and/or adhesives. Building walls are constructed using the method of forming a cladding by attaching it. Here, in addition to the underlayment and the overlayment, there are also building walls that are composed of three or more layers of architectural facing material, with an interlayer interposed between them.

In multi-story buildings, there is a stair space that connects each floor with the ability to ascend and descend freely, but this stair space consists of a building wall such as a partition wall and a staircase that stands independently from the building wall. Ru. Stairs include stringer stairs, stringer stairs, and the like, and the stringers that make up these stairs are arranged on the surface of the cladding of the building wall. Here, in this specification, "independent from the building wall" means that other members such as stairs are separate members from the building wall, and other members are in contact with the surface of the building wall. This includes both forms in which the other members are separated from the surface of the building wall.

For example, Patent Document 1 also proposes an indoor staircase with handrails that includes stringers on the sides of the wall panels. This indoor staircase with handrails has a handrail supported by an arm protruding from the wall surface of one wall panel surrounding the left and right sides of the staircase, and a stringer attached to the wall panel facing the handrail separates the steps and risers. It is divided into upper and lower parts of the upper and lower girders, and the steps and risers are inserted into the insertion grooves between the upper and lower girders.

In the partition wall 100, a plurality of studs 10 are installed between the lower runner and the upper runner at intervals of 606 mm or less (for example, intervals of 606 mm and 455 mm) in the width direction of the wall (left-right direction in FIG. 3). It's included.

Hereinafter, the fastening structure of the bottom liner, inner liner, and top liner will be explained in the order of FIGS. 1 to 3.

As shown in FIG. 1, an underlay 20 is formed by fastening a plurality of underlay members 21 in front of the plurality of studs 10 (on the front side of the page), and a staircase 80 is provided on the front side of the underlay 20. Constituent side beams 81 (an example of a building material), and a plurality of step plates 82 and risers 83 fixed to the side beams 81 are arranged.

The staircase 80 is built independently from the studs 10 and the underlayment 20, that is, independently from the partition wall 100, and between the studs 10 and the stringers 81, in addition to the underlayment 20 shown, there are A space is provided for installing the inner lining 30 and the upper lining 40. Here, although the illustrated example staircase 80 is a stringer staircase, the stringer 81 may also include a stringer, and a stringer staircase provided with stringers may be applied.

The construction method for the stairs 80 and the partition walls 100 on the sides of the stairs 80 that constitute the stairway space is as follows: First, the stairs 80 are constructed using structural members (foundation beams, floor beams on the second floor, etc.) of the upper and lower floors (for example, the first and second floors). After installing the studs 10 on the sides of the stairs 80, install the underlayment 21 in the space between the studs 10 and the stringer 81, and fasten the underlayment 21 to the studs 10. It will be done.

As the underlay surface material 21, gypsum board, gypsum board, calcium silicate board, particle board, hardboard, plywood, structural plywood, etc. are applied, and among them, gypsum board and gypsum board are preferably used. In addition to general gypsum board, gypsum board includes reinforced gypsum board, ordinary rigid gypsum board, sheathing rigid gypsum board, moisture absorbing and desorbing reinforced gypsum board, moisture absorbing and desorbing ordinary gypsum board, and moisture absorbing and desorbing sheathing rigid gypsum board. , glass fiber non-woven gypsum board, glass mat gypsum board, etc.

For example, when gypsum board is applied to the underlay surface material 21, its short side, long side, and thickness are semi-noncombustible material of 910 mm x 1820 mm x 9.5 mm, or 910 mm x 1820 mm (2420 mm, 2730 mm) x 12. It is made of noncombustible material with a thickness of 5 mm (15 mm, 21 mm, 25 mm), and the width of the gypsum board is 606 mm, 1000 mm, 1220 mm, etc. in addition to 910 mm.

The underlay surface material 21 is fastened to the stud 10 with screws 50 (an example of a first fixing member). Here, in addition to the illustrated screws, nails, screws, or the like may be used as the first fixing member.

In the illustrated example, a plurality of underlay panels 21 are vertically arranged on a plurality of studs 10. Here, a plurality of underlay surface materials 21 may be arranged horizontally.

As shown in FIG. 1, the stairs 80 have already been constructed in front of the studs 10, so when fastening the underlayment 21 to the studs 10, the side beams 81 constituting the stairs 80 are attached to the screws 50. It becomes an obstacle to typing.

The fastening pitch t1 in the general area where the stringer 81 does not become an obstacle when fastening with the screws 50 is set to, for example, about 300 mm.

On the other hand, in the area where the stringer 81 becomes an obstacle, fastening with the screws 50 is not performed, but in the upper and lower positions of the stringer 81, that is, in the area avoiding the stringer 81 (building material).

As shown in FIG. 1, the fastening pitch t2 of the screws 50 in the area avoiding the side beams 81 can be set to about 750 mm at maximum.

As shown in the illustrated example, by fastening the underlaying surface material 21 to the stud 10 with the screws 50 in an area avoiding the stringer 81, and by setting the fastening pitch t2 to a maximum of about 750 mm, the It becomes possible to smoothly fasten the underlay surface material 21 to the stud 10 while ensuring the fastening strength of the underlay surface material 21. In addition, if the fastening strength can be ensured even if the fastening pitch t2 exceeds 750 mm, the fastening pitch t2 may be set within a range exceeding 750 mm.

By fastening a plurality of underlay face materials 21 to a plurality of studs 10, a fastening structure of studs 10 and underlay 20 is formed.

Next, as shown in FIG. 2, a plurality of inner panel members 31 are fastened to the surface of the underlayment 20 (the surface facing the stringer 81).

By fastening the inner panel material 31 to the underlayment 20, the number of staples 60 can be suppressed as much as possible while increasing the strength of fastening the inner panel material 31 to the underlayment 20. Furthermore, the partition wall 100 can be fastened to the partition wall 100 during deformation during an earthquake. The integrity of the constituent members of the partition wall 100 (the ability to deform as one) can be improved, and it is possible to prevent the constituent members of the partition wall 100 from falling off (preventing the inner lining 30 from falling off from the underlay 20) in the event of a fire.

In addition, the inner panel material 31 is further fixed to the stud 10 by penetrating the underlay panel material 21 with additional screws 65 (an example of a fifth fixing member). In the illustrated example, the inner panel material 31 is fastened to the stud 10 by one additional screw 65, but two or more additional screws 65 may be used. The additional screws 65 further enhance the integrity of the stud 10, the underlay 20, and the inner lining 30. Here, the additional screws 65 may be driven from the surface of the top panel material 41, which will be described below, and may be fastened to the studs 10 by penetrating both the middle panel material 31 and the bottom panel material 21. , Preferably, it is a form in which it is driven from the surface of the lining panel material 31 in the illustrated example.

On the other hand, in areas where the stringer 81 is an obstacle, fastening with the staples 60 is not performed, but in the upper and lower positions of the stringer 81, that is, in areas avoiding the stringer 81 (building material).

As shown in FIG. 2, the fastening pitch t5 of the staples 60 in the area avoiding the stringers 81 can be set to about 750 mm at maximum.

As shown in the illustrated example, by fixing the inner panel material 31 to the underlayment 20 with staples 60 in an area avoiding the stringers 81, and setting the fastening pitch t5 to a maximum of about 750 mm, the underlayment 20 It becomes possible to smoothly fasten the inner lining material 31 to the underlayment 20 while ensuring the fastening strength of the inner lining material 31 to the underlayment 20. In addition, if the fastening strength can be ensured even if the fastening pitch t5 exceeds 750 mm, the fastening pitch t5 may be set in a range exceeding 750 mm.

The lining 30 is formed by fastening a plurality of lining face materials 31 to the lining 20, and a fastening structure of the lining 20 and the lining 30 is formed.

Next, as shown in FIG. 3, a plurality of top facing members 41 are fastened to the surface of the inner lining 30 (the surface facing the side beams 81).

As with the underlay surface material 21 and the intermediate surface material 31, gypsum board, gypsum board, calcium silicate board, etc. are applied to the top surface material 41, and among them, gypsum board and gypsum board are preferably used. For example, the base material 21 and the middle material 31 are made of reinforced gypsum board, and the top material 41 is made of general gypsum board, thereby forming the partition wall 100 with a three-layer structure and fire resistance. be done.

In the illustrated example, a plurality of top panels 41 are vertically arranged on the inner panel 30. Here, a plurality of top facing panels 41 may be arranged horizontally.

The top surface material 41 is fastened to the inner lining 30 using an adhesive such as a vinyl acetate adhesive (not shown) and staples 70 (an example of the fourth fixing member).

For example, the staples 70 are driven into the adhesive when viewed from the front, but the staples 70 may not be driven into the adhesive but at positions that do not correspond to the adhesive.

As shown in FIG. 3, the staples 70 are driven at a relatively dense pitch around the top surface material 41, and the staples 71 are driven at a relatively coarse pitch at the center of the top surface material 41. A central staple 72 is included that is driven in pitch.

As shown in FIG. 3, since the stairs 80 have already been constructed in front of the inner lining 30, when fastening the top facing material 41 to the inner lining 30, the side beams 80 constituting the stairs 80 are This becomes an obstacle to driving the

staples

71 and 72.

staples

71 and 72, the fastening pitch t6 of the peripheral staples 71 is set to about 100 mm, and the fastening pitch t7 of the center staple 72 is 200 mm. It is set to a certain degree.

In this way, the periphery of the top facing material 41 is fastened to the inner lining 30 with staples 71 having a relatively dense pitch, and the center of the top facing material 41 is fastened with staples 72 having a relatively coarse pitch. By fastening the top panel material 41 to the inner panel 30, the number of staples 70 can be suppressed as much as possible, and the strength of fixing the top panel material 41 to the inner panel 30 can be increased. The integrity of the constituent members (ability to deform as one) can be improved, and it is possible to prevent the constituent members of the partition wall 100 from falling off (preventing the top lining 40 from falling off from the inner lining 30) in the event of a fire.

On the other hand, in the area where the stringer 81 is an obstacle, the staples 70 are not fastened, but the staples 70 are fastened in the upper and lower positions of the stringer 81, that is, in the area avoiding the stringer 81 (building material).

As shown in FIG. 3, the fastening pitch t8 of the staples 70 in the area avoiding the side beams 81 can be set to about 750 mm at maximum.

As shown in the illustrated example, by fastening the top panel material 41 to the inner liner 30 with staples 70 in an area avoiding the stringers 81, and setting the fastening pitch t8 to a maximum of about 750 mm, It becomes possible to smoothly fasten the top facing material 41 to the inner lining 30 while ensuring the fastening strength of the top facing material 41 to the upholstery 30. In addition, if the fastening strength can be ensured even if the fastening pitch t8 exceeds 750 mm, the fastening pitch t8 may be set in a range exceeding 750 mm.

The top lining 40 is formed by fastening a plurality of top facing materials 41 to the middle lining 30, a fastening structure of the middle lining 30 and the top lining 40 is formed, and the bottom lining 20 is fastened to the studs 10. A partition wall 100 is formed in which the inner lining 30 is fastened to the underlay 20 and the top lining 40 is fastened to the inner lining 30.

In the cross-sectional view of the partition wall 100 shown in FIG. 4, the vertical joints 75 of the top lining 40 are, for example, open-cut joints, and an adhesive 78 is applied to the surface of the top lining 40 corresponding to the vertical joints 75. A hat joiner 77 is attached to the. Here, an adhesive 78 may be applied to the back surface of the hat joiner 77 and the hat joiner 77 may be attached to the vertical joint 75. Further, although not shown, a hat joiner may be attached to the horizontal joint by using the horizontal joint as a transparent joint. Furthermore, although not shown, a sealant may be applied between the hat joiner and the lining (including the joint). By applying the sealant, the fire resistance of the vertical joints and/or horizontal joints is improved. In addition, although not shown, the vertical joints and the horizontal joints may be butt joints. Further, although the illustrated example shows a configuration in which the hat joiner 77 is attached with adhesive 78, it is also possible to attach the hat joiner with adhesive tape or double-sided adhesive tape.

Furthermore, a strip-shaped steel plate (not shown) extending laterally may be disposed between the top lining 40 and the middle lining 30. As an example, the overlay 40 includes vertical joints 75 and horizontal joints (not shown), and a strip-shaped steel plate is placed on the back side of the overlay 40 at a position corresponding to the horizontal joint (at a predetermined height level from the floor surface). An example can be given of the arrangement. For example, a galvanized steel plate or the like is used as the steel plate, and the steel plate is bonded to the front surface of the inner lining 30 and the back surface of the top lining 40 via an adhesive such as a quick-drying bond. Note that the steel plate may be attached using staples, screws, adhesive tape, or double-sided adhesive tape in addition to adhesive bonding. Furthermore, the steel plates may be disposed at various positions between the top lining 40 and the middle lining 30 that do not correspond to the horizontal joints. Further, the steel plate may be disposed between the stud 10 and the underlay 20 or between the underlay 20 and the inner lining 30.

The steel plate functions as a support base that cantilever-supports a post-installed member (not shown) that is post-installed on the indoor side of the lining 40. For example, one end of a rod-shaped support member (not shown) is fixed to a steel plate, the other end of the support member extends into the room, and the other ends of multiple support members are retrofitted with handrails, wall hangings, backrests, armrests, etc. The member is fixed.

As described above, since the steel plate is a rigid plate material, it is suitable as a member that functions as a support base for supporting retrofitted members. Further, since the steel plate is a relatively thin plate-like member, it is suitable as a member sandwiched between the inner lining 30 and the upper lining 40. Since it is desirable that the steel plate has the minimum rigidity to support the retrofitted member and is as thin as possible, the thickness of the steel plate is preferably in the range of 0.4 mm to 1.2 mm.

According to the partition wall 100, the first fixing member 50 fastens the underlay panel material 21 to the stud 10, the third fixing member 60 fastens the inner panel material 31 to the underlay panel material 21, and the inner panel panel material 21. The respective fastening positions of the fourth fixing members 70 that fasten the top panel material 41 to the side beams 31 are set in areas avoiding the side beams 81. This makes it possible to smoothly construct the partition wall 100 with excellent fire resistance performance on the side of the staircase 80 in the staircase space where the staircase 80 is constructed first.

It should be noted that other embodiments may be adopted in which other components are combined with the configurations listed in the above embodiments, and the present disclosure is not limited to the configurations shown here. . In this regard, changes can be made without departing from the spirit of the present disclosure, and can be determined appropriately depending on the application form.
