JP, 9-60157, A

  Here, a vertical load may be applied to a building having the partition wall structure as described above due to snow on the roof or the like. In such a case, a structure such as a beam or a column may be deformed such as flexed. The deformation of the structure may cause a failure in the wall panel supported by the structure.

  The present invention has been made to solve such a problem, and when a vertical load acts on the roof and the structure is deformed, the wall panel can follow the deformation. It is intended to provide a structure.

  The partition wall structure according to the present invention is a partition wall structure for partitioning a space, and has a lower structure having at least a pillar member extending upward from the floor side, an upper structure having at least a beam member supporting a roof, and a lower part. A wall panel covering the structure and the upper structure, the wall panel including a lower panel fixed to the lower structure and an upper panel fixed to the upper structure, wherein the lower panel and the upper panel are , Connected to each other in a vertically slidable manner without a gap, forming a first gap between the upper end of the pillar member and the upper structure, and connecting the upper end of the lower panel to the upper structure. A second gap is formed between the upper structure and the upper structure at the position where the first gap is formed. Lower panel At the upper end the different positions, that in the upper support member extending vertically, comprises a gap forming member forming a second gap, a.

  In the partition wall structure according to the present invention, the wall panel includes a lower panel fixed to the lower structure and an upper panel fixed to the upper structure. In addition, the lower panel and the upper panel are connected to each other without a gap and are slidable in the vertical direction. With such a structure, the upper panel fixed to the upper structure on the roof side is connected to the lower panel fixed to the lower structure on the floor side without any gap, thereby sufficiently partitioning the space. Also, it is possible to slide in the vertical direction with respect to the lower panel, following the movement of the upper structure. Here, the upper structure includes a support member that slidably supports the upper end side of the pillar member in the vertical direction at a position where the first gap between the upper end of the pillar member and the upper structure is formed. ing. By forming such a first gap by the support member, the upper structure can smoothly move downward while suppressing interference with the column member. Further, the upper structure extends in the vertical direction above the support member at a position different from the upper end of the lower panel when viewed in the vertical direction, so that the second upper part between the upper end of the lower panel and the upper structure is provided. A gap forming member that forms a gap is provided. By forming such a second gap by the gap forming member, the upper structure can move smoothly downward while suppressing interference with the lower panel. Further, damage to the lower panel when the upper structure moves downward can be suppressed. As described above, when the vertical load acts on the roof and the structure is deformed, the wall panel can follow the deformation.

  Further, in the partition wall structure according to the present invention, the support member may have a U-shaped cross-section that opens downward. With such a configuration, the support member can sufficiently secure the pillar member by sandwiching the pillar member, and can also easily secure the first gap on the upper side of the pillar member with a simple structure.

  Further, in the partition wall structure according to the present invention, the upper end side portion of the lower panel may be arranged between the upper panel and the support member. With such a configuration, the upper end side portion of the lower panel, which is a slidable portion with respect to the upper panel, is firmly sandwiched between the upper panel and the support member. Therefore, it is possible to sufficiently maintain the state in which there is no gap between the upper panel and the lower panel.

  According to the present invention, when a vertical load acts on the roof and the structure is deformed, the wall panel can follow the deformation.

FIG. 2 is a cross-sectional view taken along the line II-II shown in FIG. FIG. 3 is a sectional view showing a partition wall structure according to a modification. FIG. 4 is a sectional view showing a partition wall structure according to a modification.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent elements will be denoted by the same reference symbols, without redundant description.

  As shown in FIG. 1, a building 1 such as a general house or factory includes a roof 2 and a structural body 3 that supports the roof 2. The roof 2 is a member that extends horizontally in the upper side of the building 1. The roof 2 is made of, for example, a corrugated steel plate, and may include a heat insulating material such as rock wool or glass wool. The structural skeleton 3 is a skeleton that forms the main structure of the building 1. The structural skeleton 3 includes columns (not shown) arranged at corners and ends of the building 1, beam members 4 bridged between the columns, and a concrete floor 6. A steel material such as a shaped steel such as H steel or a square steel pipe for general structure is used for the pillar or the beam member 4 that constitutes the structural body 3. The roof 2 is fixed to the upper end of the beam member 4. That is, the roof 2 is supported by the pillar and the beam member 4.

  The building 1 includes a partition wall 7. The partition wall 7 may be a partition wall having fireproof performance for forming a fireproof partition in the building 1. However, the partition wall 7 is not limited to the one for forming the fireproof partition, and may be for partitioning the space for other uses. Such a partition wall 7 is configured by the partition wall structure 10 according to this embodiment.

  The partition wall structure 10 according to the present embodiment will be described in detail with reference to FIG. The partition wall structure 10 includes a lower structure 11, an upper structure 12, and a wall panel 13. The wall panel 13 is a panel that covers the lower structure 11 and the upper structure 12. The wall panel 13 covers the entire area in the vertical direction from the concrete floor 6 to the roof 2 without any gap. As a result, when the fireproof compartment is formed, the wall panel 13 ensures the fire resistance of the partition wall structure 10. Such a wall panel 13 prevents smoke, flames, etc. generated in the fireproof compartment from leaking to the outside. The wall panel 13 includes a lower panel 16 fixed to the lower structure 11 and an upper panel 17 fixed to the upper structure 12. In the following description, the vertical direction is the “vertical direction D1”, the direction in which the partition wall structure 10 expands is the “width direction D2” in the horizontal direction, and the horizontal direction orthogonal to the width direction D2 is the “thickness direction”. The following description will be given as "D3". In this specification, “fixed” means that one member and another member are connected to each other in a state in which movement in any of the up-down direction D1, the width direction D2, and the thickness direction D3 is restricted. It refers to the state of being Therefore, the state of being slidable in either direction does not correspond to “fixation”.

  The lower structure 11 is a structure that is arranged on the lower side and fixed to the concrete floor 6 among the structures that form the skeleton of the partition wall structure 10. The lower structure 11 has at least a pillar member 20 extending upward from the concrete floor 6. The lower structure 11 is configured by arranging a plurality of pillar members 20 at predetermined intervals in the width direction D2 (see FIG. 1).

  The column member 20 is made of a square steel material such as a stud. The cross-sectional shape of the pillar member 20 is not particularly limited and may be, for example, an H shape, a U shape, or the like. In the form shown in FIG. 2, the pillar member 20 includes side walls 21 and 21 facing each other in the thickness direction D3, and side walls 22 extending in the thickness direction D3 so as to connect the side walls 21 and 21 to each other. The lower end of the pillar member 20 is fixed to the concrete floor 6, and the upper end 20a of the pillar member 20 is arranged at a position spaced below the roof 2.

  The lower panel 16 of the wall panel 13 is a fire resistant panel. The lower panels 16 and 16 are arranged so as to sandwich the pillar member 20 from both outsides in the thickness direction D3. The lower panels 16 and 16 are provided so as to contact the outer surfaces of the side walls 21 and 21 of the column member 20. The lower panels 16 and 16 are fixed to the column member 20. Specifically, the pair of lower panels 16, 16 are fixed to the side walls 21, 21 of the pillar member 20 via the fixing member 24. Although a pin is illustrated as the fixing member 24, a bolt or the like may be applied. The fixing member 24 fixes the lower panel 16 and the side wall 21 at a position spaced downward from the upper end 20a of the pillar member 20. The lower end of the lower panel 16 reaches the concrete floor 6. The upper end 17a of the lower panel 16 extends to a position above the upper end 20a of the pillar member 20.

The upper structure 12 is a structure that is arranged on the upper side and fixed to the roof 2 among the structures that form the skeleton of the partition wall structure 10. The upper structure 12 has at least a beam member 4 that supports the roof 2 and extends in the horizontal direction. Further, the upper structure 12 includes a gap forming member 30 for forming a second gap G2 (details will be described later) between the lower panel 16 and the upper structure 12. The upper structure 12 also includes a support member 31 that supports the upper end of the pillar member 20 so as to be slidable in the up-down direction D1.

  The gap forming member 30 is a member for forming the second gap G2 by arranging the support member 31 at a position spaced downward from the lower end 4a of the beam member 4. In the present embodiment, the gap forming member 30 is made of a rectangular steel material having a rectangular cross section and extending in the width direction D2, but any member can be used as long as it can secure a distance. May be adopted. The upper end 30a of the gap forming member 30 is fixed to the lower end 4a of the beam member 4 by welding or the like.

  The support member 31 is a member having a U-shaped cross section that opens downward. The support member 31 extends in the width direction D2 with the cross-sectional shape. The support member 31 includes side walls 32 and 32 facing each other in the thickness direction D3 for sandwiching the pillar member 20, and an upper wall 33 connecting the side walls 32 and 32 to each other on the upper end side. The upper surface of the upper wall 33 is fixed to the lower surface of the gap forming member 30 by welding or the like. The side walls 32, 32 are in contact with the upper ends of the outer surfaces of the side walls 21, 21 of the pillar member 20 to support the upper end of the pillar member 20. A first gap G1 is formed between the upper end 20a of the pillar member 20 and the upper wall 33 of the support member 31. That is, the support member 31 supports the upper end 20a side of the pillar member 20 slidably in the vertical direction D1 at the position where the first gap G1 is formed. The support member 31 and the pillar member 20 are not fixed by a pin or a screw, but can slide at least in the vertical direction D1. The side walls 32, 32 enter between the lower panels 16, 16 and the side walls 21, 21 of the pillar member 20. Since the fixing member 24 is arranged at a position lower than the side walls 32, 32 of the supporting member 31, the side walls 32, 32 and the lower panels 16, 16 are not fixed and can be slid at least in the vertical direction D1. ..

  The upper panel 17 of the wall panel 13 is a fire resistant panel. The upper panel 17 includes panels 17A arranged so as to sandwich the beam member 4 from both outsides in the thickness direction D3, a panel 17B wrapping around the lower end side of the beam member 4, and an outside of the gap forming member 30 and the support member 31. And a panel 17C to be arranged.

  The panel 17A of the upper panel 17 is provided so as to come into contact with the outer end portions of the upper and lower flange portions 4A and 4B of the beam member 4. The panel 17A is fixed to the beam member 4. Specifically, the pair of panels 17A, 17A is fixed to the outer end of the beam member 4 via a fixing member 38 and a clasp 37. Although a pin is illustrated as the fixing member 38, a bolt or the like may be applied. Further, the stopper 37 is fixed to the beam member 4 vertically and is configured to be able to receive the fixing member 38. The fixing member 38 fixes the panel 17A and the clasp 37 at a position between the upper and lower flange portions 4A and 4B. The upper end of the panel 17A reaches the roof 2. The lower end of the panel 17A extends below the lower end 4a of the beam member 4.

  The panel 17C of the upper panel 17 is provided so as to contact the outer surface of the lower panel 16. The panel 17C is fixed to the gap forming member 30. Specifically, the pair of panels 17C, 17C is fixed to the outer end of the gap forming member 30 via a fixing member 35 and a clasp 36. Although the pin is illustrated as the fixing member 35, a bolt or the like may be applied. Further, the stopper 36 is fixed to the outer side surface of the gap forming member 30 and is configured to be able to receive the fixing member 35. The fixing member 35 fixes the panel 17C and the clasp 36 at a position on the upper end side of the gap forming member 30. The upper end of the panel 17C reaches the lower end 4a of the beam member 4. The lower end of the panel 17C extends below the upper end 16a of the lower panel 16.

  The inner surface 17Ca of the panel 17C and the outer surface 16b of the lower panel 16 are in contact with each other without a gap to ensure fire resistance, and at the same time, are configured to be slidable at least in the vertical direction D1 without being fixed. That is, the lower panel 16 and the upper panel 17 are connected to each other without a gap and being slidable in the vertical direction D1. The slidable and connected state means that when the structures are in contact with each other without a gap and a load is applied to the structure such as when the roof 2 is covered with snow, the structure is at least in the vertical direction D1. It is ready to move to. When a pin or the like is inserted between the lower panel 16 and the upper panel 17, the fixing member such as the pin is not inserted because the sliding in the vertical direction D1 is restricted. The lower panel 16 and the upper panel 17 are slidably connected to each other over the entire area in the width direction D2 without a gap. The overlapping amount of the panel 17C and the lower panel 16 is set to such an amount that a sufficient stroke can be ensured when the roof 2 slides on each other due to snowfall or the like. Further, of the lower panel 16 and the panel 17C, the surfaces that come into contact with each other (and the surfaces that can come into contact when sliding) may be processed to make them slippery. For example, a slippery member such as a poly film may be arranged on the surface. The panel 17B extends horizontally from the lower end of the panel 17A toward the upper end of the panel 17C in the thickness direction D3. The panel 17B is fixed to each of the panel 17A and the panel 17C without a gap.

  Here, the upper end 16a of the lower panel 16 is the lower side of the gap forming member 30 and is arranged at a position different from the gap forming member 30 (a different position in the thickness direction D3) when viewed in the vertical direction D1. . As a result, a second gap G2 is formed between the upper end 16a of the lower panel 16 and the upper structure 12 (here, the lower end of the clasp 36 described later). The second gap G2 is formed on both lateral sides of the gap forming member 30. That is, it can be said that the gap forming member 30 is a member that forms the second gap G2 by extending in the vertical direction D1 at a position different from the upper end 16a of the lower panel 16 when viewed in the vertical direction D1. Although the upper end 16a of the lower panel 16 is arranged at the same position as the upper wall 33 of the support member 31 in the present embodiment, it may not be at the same position and may be displaced in the vertical direction D1. The second gap G2 and the first gap G1 between the upper end 20a of the pillar member 20 and the upper wall 33 of the support member 31 are the lower structure 11 and the lower panel 16 due to snow accumulated on the roof 2, and the like. When the upper structure 12 and the upper panel 17 relatively slide in the vertical direction D1, the upper structure 12 and the upper panel 17 function as a space for ensuring a stroke for the slide. The first gap G1 and the second gap G2 may be set to the same size, or may be set to different sizes within a range that does not affect the sliding movement.

  Next, the operation and effect of the partition wall structure 10 according to this embodiment will be described.

  For example, as a comparative example, there is a partition wall structure in which a wall panel is not divided into an upper panel and a lower panel and is fixed to both the upper structure and the lower structure. In the partition wall structure according to the comparative example, when a load is applied in the vertical direction due to snow accumulated on the roof or the like, the structures such as beams and columns may be deformed such as flexure. Deformation of the structure may cause failure of the wall panel supported by the structure. If the partition wall structure is a wall structure for a fireproof compartment, it may not be possible to sufficiently divide the space because smoke or the like may enter from the defective portion of the wall panel.

  On the other hand, in the partition wall structure 10 according to the present embodiment, the wall panel 13 includes a lower panel 16 fixed to the lower structure 11 and an upper panel 17 fixed to the upper structure 12. In addition, the lower panel 16 and the upper panel 17 are connected to each other without a gap and are slidable in the vertical direction D1. With such a structure, the upper panel 17 fixed to the upper structure 12 on the roof 2 side is connected to the lower panel 16 fixed to the lower structure 11 on the floor side without any gap, thereby providing a space. While sufficiently partitioned, the lower panel 16 can slide in the up-down direction D1 following the movement of the upper structure 12. Here, the upper structure 12 slides on the upper end 20a side of the column member 20 in the vertical direction D1 at a position where the first gap G1 between the upper end 20a of the column member 20 and the upper structure 12 is formed. A supporting member 31 that supports the movable member 31 is provided. By forming such a first gap G1 by the support member 31, the upper structure 12 can move smoothly downward while suppressing interference with the column member 20. Further, the upper structure 12 extends in the vertical direction D1 above the supporting member 31 at a position different from the upper end 16a of the lower panel 16 when viewed from the vertical direction D1, so that the upper structure 16 and the upper structure 16 of the lower panel 16 and the upper structure. A gap forming member 30 that forms a second gap G2 with the body 12 is provided. By forming such a second gap G2 by the gap forming member 30, the upper structure 12 can move smoothly downward while suppressing interference with the lower panel 16. In addition, damage to the lower panel 16 when the upper structure 12 moves downward can be suppressed. As described above, when the vertical load acts on the roof 2 and the structure is deformed, the wall panel 13 can follow the deformation.

  In addition, in the partition wall structure 10 according to the present embodiment, the support member 31 has a U-shaped cross section that opens downward. With such a configuration, the support member 31 sufficiently supports the pillar member 20 by sandwiching the pillar member 20, and also easily secures the first gap G1 on the upper side of the pillar member 20 with a simple structure. be able to.

  Further, in the partition wall structure 10 according to the present embodiment, the portion of the lower panel 16 on the upper end 16 a side is arranged between the upper panel 17 and the support member 31. With such a configuration, the portion on the upper end 16a side of the lower panel 16, which is a portion that can slide with respect to the upper panel 17, is firmly sandwiched between the upper panel 17 and the support member 31. Therefore, it is possible to sufficiently maintain the state in which there is no gap between the upper panel 17 and the lower panel 16.

  The present invention is not limited to the above embodiments.

  For example, a partition wall structure 100 as shown in FIG. 3 may be adopted. In this partition wall structure 100, the wall portion configured by the lower structure 11 and the lower panel 16 is eccentric to the beam member 4 in the thickness direction D3 (here, eccentric to the right side of the drawing). Are located). The support member 31 and the gap forming member 30 of the upper structure 12 are arranged at positions where a part of the lower flange portion 4B of the beam member 4 protrudes from the end portion on the right side of the drawing. As a result, the upper panel 17 on the right side of the drawing is configured by the panel 17D that extends straight in the vertical direction D1 between the roof 2 and the lower panel 16. The shape of the clasp is not particularly limited, and clasps 41 and 42 that are long in the vertical direction D1 as shown in FIG. 3 may be used.

  Further, a partition wall structure 200 as shown in FIG. 4 may be adopted. In this partition wall structure 200, the wall portion constituted by the lower structure 11 and the lower panel 16 is separated from the beam member 4 in the thickness direction D3 (here, separated from each other on the right side of the drawing). It is located in. The upper structure 12 includes a beam member 50 that extends from the flange portion 4B of the beam member 4 toward one side (the right side in the drawing) in the thickness direction. The beam member 50 is connected to the beam member 4 via a metal fitting 51. The beam member 50 is provided with a support member 31 and a gap forming member 30 at positions where the lower structure 11 and the lower panel 16 are arranged. The upper panel 17 is composed of panels 17E, 17E extending straight in the up-down direction D1 between the roof 2 and the lower panels 16, 16 on both sides. The panels 17E and 17E are fixed by a fixing member 54 by a corner member 70 provided on the upper surface of the beam member 50 and a stopper 53 supported by the corner member 70. The panels 17E, 17E have through holes at positions where the beam members 50 pass.

  Although the support member and the gap forming member are configured as separate components, they may be integrally formed and configured as the same component as long as the above-described effects can be obtained.

  Further, the arrangement, combination, and the like of the members such as the beams, columns, and steel materials are not particularly limited, and the configuration of the wall panel may be appropriately changed without departing from the spirit of the present invention.
