Description

  The present invention relates to an attachment structure for a partition wall provided between an indoor floor and a ceiling to partition the room.

Conventionally, it is well known to use a partition wall to partition an indoor space in a building. The floor plan in the building varies from family to family due to differences in family structure and lifestyle. Even in the same family, the floor plan required changes depending on the growth of children. As a result, many types of floor plans are required to provide buildings.
On the other hand, it is necessary to satisfy a predetermined seismic performance standard in the structural calculation necessary for creating the structural calculation document submitted at the time of building confirmation application in building construction.
In general, seismic force and wind pressure act on the center of gravity or centroid position of each floor as a horizontal force. If the partition walls that bear the horizontal force in the horizontal direction (same level) are partially concentrated, the rigid center position (rigid center or centroid) and the center of gravity position may deviate. If there is a difference between the positions of the rigid center and the center of gravity, a couple is generated between the rigid center and the center of gravity, and a torsional moment acts on the building. In addition, when the variation in the rigidity of the floors in the vertical direction is large, stress concentrates on the floor with low rigidity.

Therefore, the partition wall does not bear horizontal force by allowing the upper end of the partition wall to move along the longitudinal direction so that the horizontal displacement of the structural frame is not transmitted to the partition wall. Has been studied (for example, Patent Document 1).
Since the partition wall as shown in Patent Document 1 is fixed to the floor and is movable with respect to the ceiling, the partition wall does not act as a load bearing wall that supports the force from the horizontal direction. This partition wall does not become an element that affects the rigidity of the building or the position of the rigid center. That is, the arrangement of the partition walls does not affect the earthquake resistance performance of the building. Even if the partition walls are unevenly distributed, there is no unevenness in the rigidity of the building, and the seismic performance of the building will not be reduced.

JP 2012-97519 A

In the conventional technique shown in Patent Document 1, the partition wall is not fixed to the ceiling and is movable within a predetermined range, but is fixed to the floor. Since the upper end of the partition wall is movable, it is necessary to firmly fix the partition wall with the floor only at the lower end. The lower frame member is fixed in a state where it is embedded in the floor (FIG. 1), and is fixed to the floor. The face material of the partition wall is fixed with a nail or the like to the embedded lower frame member or the like.
On the other hand, in order to form various free floor plans as described above, it is necessary to freely change the position of the partition wall. However, in the prior art as described above, it is not easy to remove the location where the lower end of the partition wall is firmly fixed and remove the lower frame member embedded in the floor to provide a flat floor, and change the layout of the partition wall There was a problem that was not easy.
Especially when a barrier-free flat floor is desired, it is difficult to change the layout when the partition wall is fixed to the floor as described above, and it is difficult to set the floor plan freely. Become.

The invention described in claim 1 has been made in view of the above-described problems of the prior art, and the object of the invention is not to consider the rigidity bias associated with the arrangement of the partition walls. Another object of the present invention is to provide a partition wall mounting structure in which a partition wall can be freely arranged and the partition wall layout can be easily changed.
In addition to the object of the invention described in claim 1, the invention described in claim 2 has a simple structure and the floor moves in conjunction with the partition wall even when the partition wall moves due to seismic force or the like. It is an object of the present invention to provide a partition wall mounting structure that can suppress this.
In addition to the object of the invention described in claim 2, an object of the invention described in claim 3 is to provide a partition wall mounting structure capable of smoothly moving the partition wall relative to the floor.

(Claim 1)
The invention described in claim 1 is characterized by the following points. That is, the mounting structure of the partition wall 600 provided between the indoor floor 650 and the ceiling 660, which partitions the room, and the partition wall 600 includes an upper frame 630 disposed along the lower surface of the ceiling 660. A lower frame 610 disposed horizontally along the upper surface of the floor 650, and a wall surface 645 disposed along the vertical direction and passed from the upper frame 630 to the lower frame 610, 630 is fixed to the ceiling 660, and the lower frame 610 is movably attached to the floor 650.
Here, “the lower frame 610 is movably attached to the floor 650” means that the lower frame 610 is relatively fixed to the floor 650 because the lower frame 610 is not fixed to the floor 650. It means that it can move. The moving direction is preferably at least the horizontal direction (horizontal direction) and movable in the longitudinal direction of the lower frame 610.

Further, the “wall surface 645” is not limited to the planar body, and may have an opening in a part thereof, and the final finish is free. The wall surface 645 is “passed from the upper frame 630 to the lower frame 610” means that the wall surface 645 is passed between the upper frame 630 and the lower frame 610 and covers all or a part between them. Means state. The wall surface 645 may be directly fixed to the upper frame 630 and the lower frame 610, but is not limited thereto. For example, a vertical frame 640 standing in the vertical direction may be formed between the upper frame 630 and the lower frame 610, and a wall surface 645 may be fixed to the vertical frame 640.
Here, when the partition wall is fixed to both the ceiling and the floor and corresponds to a wall having the ability to resist horizontal force, that is, a so-called load-bearing wall, the partition wall is arranged in the structural calculation related to earthquake resistance. It is necessary to carry out structural calculations for the entire building in consideration. In this case, it is necessary to separately perform the structural calculation of the entire building in consideration of the layout of the partition walls, even for buildings having the same configuration of the buildings other than the partition walls and different only in the layout of the partition walls.

On the other hand, in the present invention, the upper frame 630 of the partition wall 600 is fixed to the ceiling 660, and the lower frame 610 is movably attached to the floor 650. For this reason, the partition wall 600 is in a state substantially similar to the state suspended from the ceiling 660. The partition wall 600 similar to the suspended state does not transmit the horizontal force generated during the earthquake between the ceiling 660 and the floor 650, and does not have the ability to resist the horizontal force. It becomes a bearing wall. For this reason, even if the arrangement of the partition walls 600 is different, the seismic strength of the building is not affected.
For this reason, it is not necessary to consider the rigidity bias accompanying the arrangement of the partition wall 600 in the structural calculation, and the partition wall 600 can be freely arranged.
The upper frame 630 of the partition wall 600 is fixed to the ceiling 660, and the lower frame 610 is attached to the floor 650 so as to be movable. Compared with the case where the lower end of the partition wall is fixed to the floor side, the lower end of the partition wall 600 is moved to the floor 650, and the original flat floor 650 without the partition wall 600 is provided. It is relatively easy to return to the state. That is, the arrangement of the partition wall 600 can be easily changed as compared with the case where the lower end of the partition wall is fixed to the floor.

(Claim 2)
The invention described in claim 2 is characterized by the following points in addition to the features of the invention described in claim 1 described above. That is, the lower frame 610 is provided with a long hole 612 along the longitudinal direction thereof, and a fastener 614 for fastening the lower frame 610 and the floor 650 is inserted through the long hole 612. The lower frame 610 and the floor 650 are fastened by the fastener 614 inserted through the lower frame 610 so that the lower frame 610 is attached to be movable in the longitudinal direction within the range of the long hole 612. It is characterized by.
Here, “the lower frame 610 is provided with a long hole 612 along its longitudinal direction” means that the longitudinal direction of the lower frame 610 and the longitudinal direction of the long hole 612 are parallel to each other. Means that. The longitudinal direction of the long hole 612 means a direction parallel to the long diameter of the long hole 612 having a long diameter and a short diameter and opening in a substantially elliptical shape.

Further, “the lower frame 610 is movable in the longitudinal direction within the range of the elongated hole 612” means that the lower frame 610 is within a length range of the longitudinal direction of the elongated hole 612 (so-called major axis direction). This means that it can move in the longitudinal direction of the lower frame 610.
In the present invention, the long hole 612 provided in the lower frame 610 is provided along the longitudinal direction of the lower frame 610. A fastener 614 is inserted into the long hole 612, and the lower frame 610 and the floor 650 are fastened by the fastener 614. The lower frame 610 and the floor 650 are only fastened in the vertical direction by the fasteners 614, and are not fixed so that they cannot move in the horizontal direction. The lower frame 610 and the floor 650 are relatively movable within a range in which the fastener 614 inserted through the long hole 612 can move within the long hole 612.

For this reason, when a horizontal force is applied to the ceiling 660 by a horizontal force such as seismic force, and the horizontal force is applied to the partition wall 600 fixed to the ceiling 66, the lower frame 610 is against the floor 650. And move within the range of the long hole 612 along the longitudinal direction of the long hole 612.
Accordingly, even when the partition wall 600 moves in the longitudinal direction of the lower frame 610, the floor 650 can be suppressed from moving in conjunction with the partition wall 600.
As a result, the partition wall 600 does not become a wall (bearing wall) having the ability to resist horizontal forces (forces from the side) such as earthquakes and winds in buildings with the simple structure as described above. Become. In the present invention, since the partition wall 600 does not correspond to such a load-bearing wall, the structural calculation of the building in the seismic design can be performed without being affected by the arrangement of the partition wall 600.

(Claim 3)
The invention described in claim 3 is characterized in that, in addition to the feature of the invention described in claim 2, the width of the elongated hole 612 is larger than the diameter of the fastener 614.
Here, the “width of the long hole 612” means the width of the long hole 612 in a direction (so-called short diameter direction) orthogonal to the longitudinal direction (so-called long diameter direction) of the long hole 612.
Since the width of the long hole 612 is larger than the diameter of the fastener 614, a gap (play) is formed between the width of the long hole 612 and the diameter of the fastener 614. For this reason, even when the horizontal force applied to the building due to seismic force or the like is not parallel to the longitudinal direction of the long hole 612, the frictional force between the fastener 614 and the long hole 612 becomes large, and the fastener 614 Can be prevented from being caught in the middle of the long hole 612.

Therefore, the lower frame 610 can be smoothly moved with respect to the floor 650, and the partition wall 600 can be prevented from being a load bearing wall having the ability to resist horizontal force.
As a result, the partition wall 600 can be moved smoothly with respect to the floor 650, and the partition wall 600 can be reliably made a non-bearing wall.

Since this invention is comprised as mentioned above, there exists an effect as described below.
According to the first aspect of the present invention, it is not necessary to take into account the rigidity bias associated with the arrangement of the partition walls, and it is possible to arrange the partition walls freely and to change the arrangement of the partition walls easily. An attachment structure can be provided.
According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, the floor moves in conjunction with the partition wall with a simple structure even when the partition wall moves due to seismic force or the like. It is possible to provide a partition wall mounting structure in which such a situation can be suppressed.
According to invention of Claim 3, in addition to the effect of invention of Claim 2 mentioned above, the attachment structure of the partition wall which can move a partition wall smoothly with respect to a floor can be provided.

The upper frame 630 is not formed with the long hole 612 provided in the lower frame 610, and the coach screw 616 as the fastener 614 is directly connected to the upper frame 630, the upper surface body 682, and the partition receiving member 670 (or the second floor). The floor 650 is screwed into the beam 800). Therefore, on the ceiling 660 side, the upper frame 630, the upper surface body 682, and the partition receiving member 670 (or the beam 800) are firmly fixed via the coach screw 616.
The long hole 612 opens in a substantially elliptical shape on the surface of the lower frame 610, and is formed so that the major axis direction thereof is parallel to the longitudinal direction of the partition wall 600. Therefore, the lower frame 610 is fixed so as to be movable along the longitudinal direction of the long hole 612.

A plate-like wall surface 645 is fixed on each indoor side partitioned by the partition wall 600. The wall surface 645 is fixed to the end faces of the upper frame 630, the vertical frame 640, and the lower frame 610 with a fixing tool 646 (see FIG. 8) made of screws, so that the wall surface 645 and the upper frame 630 are located inside the partition wall 600. A space surrounded by the vertical frame 640 and the lower frame 610 is formed. Due to the presence of the wall surface 645, the room partitioned by the partition wall 600 is divided. Note that the fixture 646 may use a nail, and may use an adhesive.
The interior space of the partition wall 600 is a space that is not filled with anything. In addition, it is not limited to this, You may fill with the sound-absorbing heat insulating material etc. which consist of fibrous glass wool. Further, a plurality of reinforcing materials may be provided between the vertical frames 640 in the internal space of the partition wall 600.

As a result, the lower frame 610 of the lower end of the partition wall 600 is substantially the same as the state where it is only placed on the floor 650, and this partition wall 600 is substantially the same as the state suspended from the ceiling 660 of the same level. That is, the partition wall 600 has the same deformation behavior and operation as that suspended from the ceiling 660 of the same level against the horizontal force of seismic force and wind pressure, that is, so-called horizontal force. . The horizontal force due to the seismic force or the like on the partition wall 600 acts on the ceiling 660 of the floor where the partition wall 600 is provided.
As shown in FIG. 7, a coach screw 616 as a fastener 614 is inserted through the long hole 612 and the lower end of the coach screw 616 is screwed into the lower surface body 681 and the partition receiving member 670. A round washer 618 is sandwiched between the head 621 of the coach screw 616. The diameter of the circular washer 618 is formed so as to be larger than the opening width P of the long hole 612 in the short diameter direction and smaller than the opening length Q of the long hole 612 in the long diameter direction. Further, in order to prevent a frictional force between the coach screw 616 and the long hole 612 from increasing, the long hole 612 has an opening width P in the short diameter direction larger than the outer diameter of the shaft portion 622 of the coach screw 616. 612 is opened. The fastener 614 is screwed into the floor 650 at a substantially central position of the opening length Q in the longitudinal direction of the long hole 612.

As shown in FIG. 8, the lower frame 610 of the lower part of the partition wall 600 is attached to the lower surface body 681 and the partition receiving member 670 in a state that it can be moved through the long hole 612 by a coach screw 616 as a fastener 614. ing. The upper frame 630 on the upper part of the partition wall 600 is in a state in which movement with respect to the upper surface body 682 of the ceiling 660 and the partition receiving member 670 is restricted (a state where it cannot move) by the coach screw 616 as the fastener 614. It is firmly fixed.
Wall surfaces 645 are fixed to both side surfaces of the partition wall 600 by a fixture 646 made of a screw.

As shown in FIG. 9, on the first floor of the dome-shaped structure 10, the upper part (specifically, the upper frame 630) of the partition wall 600 is fixed to the ceiling 660 of the first floor, and the lower part (specifically, the partition wall 600). The lower frame 610) is attached so as to be movable with respect to the floor 650 on the first floor. That is, the partition wall 600 on the first floor is in the same state as that suspended from the ceiling 660 on the first floor, and a horizontal force due to seismic force or the like acts on the ceiling 660 on the first floor.
On the second floor of the dome-like structure 10, the upper part of the partition wall 600 (specifically, the upper frame 630) is fixed to the ceiling 660 of the second floor, and the lower part of the partition wall 600 (specifically, the lower frame 610) is two. It is attached in a movable state to the floor 650 of the floor. That is, the partition wall 600 on the second floor is in the same state as that suspended from the ceiling 660 on the second floor, and a horizontal force due to seismic force or the like acts on the ceiling 660 on the second floor.

  On the second floor of the dome-shaped structure 10, the height from the floor 650 on the second floor is at the level of a human waist, the lower part is fixed to the floor 650 and the upper part does not reach the ceiling 660 601 is formed. Similar to the partition wall 600, the wall 601 also has a wall surface, an upper frame, a lower frame, and a vertical frame (not shown). Although not particularly illustrated, the lower frame of the front wall 601 is not formed with the first slot 612 as described in the partition wall 600, and the lower frame of the wall 601 is directly connected to the floor 650 on the second floor. It is firmly fixed by the coach screw 616. That is, the coach screw 616 is directly screwed into the lower frame, the lower surface body 681, and the partition receiving member 670, and is fixed in an integrated state. The horizontal force due to the seismic force or the like at the crossing wall 601 directly acts on the floor 650 on the second floor.

A hanging wall 602 that hangs down from the ceiling 660 to the middle of the floor 650 is formed on the ceiling 660 of the first floor. The hanging wall 602 is also formed by wall surfaces, an upper frame, a lower frame, a vertical frame, and the like that are substantially the same as the partition wall 600 (not shown). The lower frame of the hanging wall 602 is not connected to the floor 650 at all. Although not shown in the drawing, the upper frame of the hanging wall 602 is an upper surface 682 of the ceiling 660 on the first floor by a coach screw 616 as a fastener 614. And fixed to the partition receiving member 670. The horizontal force due to the seismic force or the like on the hanging wall 602 directly acts on the ceiling 660 of the first floor.
Since the partition wall 600 provided on the second floor of the dome-shaped structure 10 has a hemispherical ceiling 660 on the second floor, the upper frame 630 of the partition wall 600 matches the shape of the ceiling 660 on the second floor. Is formed. Specifically, since the ceiling 660 on the second floor is formed in a hemispherical shape by connecting a plurality of triangular structures 40, the upper frame 630 of the partition wall 600 is also formed of the plurality of triangular structures 40. It is formed so as to match the shape.

(Function and effect)
In general, a load-bearing wall that supports the horizontal force (horizontal force) of seismic force and wind pressure with the upper and lower ends of the wall fixed to the ceiling and floor is parallel along the longitudinal direction of the upper and lower ends of the wall. It has resistance against external force in the horizontal direction. On the other hand, if the upper end or lower end of the wall can be freely moved along the longitudinal direction, the wall has no resistance in that direction and should not act as a load-bearing wall that supports horizontal forces. become.
In the present embodiment, as shown in FIG. 8, the upper frame 630 of the partition wall 600 is firmly fixed to the ceiling 660 by a fastener 614 and movement is restricted. The lower frame 610 of the partition wall 600 is simply attached to the floor 650 through the long hole 612 so as to be movable, and the lower frame 610 and the floor 650 are not firmly fixed.

Specifically, as shown in FIG. 7, the fastener 614 inserted through the long hole 612 of the lower frame 610 is screwed into the floor 650, and is screwed into the head 621 and the round washer 618 of the fastener 614 and the floor 650. The lower frame 610 is sandwiched between the shaft portion 622. A gap (play) is provided between the outer diameter of the fastener 614 and the long hole 612, and the lower frame 610 is easily movable by a horizontal force such as seismic force within the range of the gap.
Since a gap (play) is formed between the width of the long hole 612 in the short diameter direction and the diameter of the fastener 614, the horizontal force applied to the building due to seismic force or the like is relative to the long direction of the long hole 612. Even when they are not parallel to each other, it is possible to prevent the friction force between the fastener 614 and the long hole 612 from increasing and the fastener 614 from being caught in the middle of the long hole 612.

The long hole 612 provided in the lower frame 610 of the partition wall 600 is opened so that the major axis direction thereof is parallel to the longitudinal direction of the lower frame 610. A fastener 614 for fastening the floor 650 and the lower frame 610 is inserted through the long hole 612. When horizontal force such as seismic force is applied to the ceiling 660, horizontal force is also applied to the partition wall 600 fixed to the ceiling 660, and the lower frame 610 of the partition wall 600 is applied to the floor 650 within the range where the long holes 612 are opened. On the other hand, it moves relatively deformed.
That is, the partition wall 600 operates as if it is suspended from the ceiling 660 with respect to a horizontal force such as seismic force, and has the same deformation behavior as when suspended from the ceiling 660. . For the vertical load on the partition wall 600, the upper frame 630 of the partition wall 600 is fixed to the ceiling 660, and the lower frame 610 is in contact (landing) with the floor 650. The direction load is transmitted to the upper and lower floors.

The partition wall 600 behaves and operates in the same way as when suspended from the ceiling 660 with respect to the horizontal force. Therefore, the partition wall 600 applies the horizontal force generated during an earthquake within the range of the long hole 612 to the ceiling. No transmission between 660 and floor 650. This partition wall 600 is not a bearing wall that transmits horizontal force such as seismic force, but is a non-bearing wall that does not have the ability to resist horizontal force.
In other words, the partition wall 600 is positioned as a secondary member that does not contribute as a load bearing wall with the ability to resist horizontal force (horizontal force) of seismic force and wind pressure, and contributes to the horizontal rigidity of the building against the horizontal force. Will not contribute.
As a result, the partition wall 600 according to the present embodiment does not affect the seismic strength of the building even if the position, direction, and the like of the partition wall 600 are different.

For this reason, it is not necessary to consider the rigidity bias accompanying the arrangement of the partition wall 600 in the structural calculation, and the partition wall 600 can be freely arranged.
The upper frame 630 of the partition wall 600 is fixed to the ceiling 660, and the lower frame 610 is attached to the floor 650 so as to be movable. Here, the upper end of the partition wall 600 is fixed and the lower end of the partition wall 600 is fixed as in the present embodiment as compared with the case where the upper end of the partition wall is made movable and the lower end is firmly fixed to the floor side. Can be relatively easily restored to the state of the original flat floor 650 in which the partition wall 600 is not provided. That is, the arrangement of the partition wall 600 can be easily changed as compared with the case where the lower end of the partition wall is firmly fixed to the floor.

  The partition wall 600 described in the above-described embodiment is provided in the dome-shaped structure 10, but the building to which the partition wall 600 having the long holes 612 as described above is attached is limited to the dome-shaped structure 10. It is not something. The partition wall 600 mounting structure according to the present embodiment can also be applied to the partition wall 600 for partitioning a room in a normal building other than the dome-shaped structure 10. When applied, even in ordinary buildings other than the dome-shaped structure 10, the same operations and effects as those described above can be achieved.

  Although not particularly illustrated, a cushioning material made of a foam-like synthetic resin, a fiber structure, or the like may be provided between the lower surface of the lower frame 610 of the partition wall 600 and the upper surface of the floor 650. Thereby, the frictional resistance between the lower frame 610 and the floor 650 is reduced, and the movement of the lower frame 610 can be made smoother. In addition, at the time of installation, the cushioning material serves as a spacer, and the interval between the lower frame 610 and the floor 650 can be maintained at a predetermined interval, so that the installation can be facilitated.

  Further, in the present embodiment, as shown in FIG. 4, the main column 700 is provided with a column main body member 730 made of laminated material between a column base member 720 made of steel and a central beam receiving member 740. Yes. The main pillar 700 is not integrally formed of metal as a whole, but is formed by assembling three different constituent members. For this reason, when the position of the vent 652 of the dome-shaped structure 10 is different, only the central beam receiving member 740 is replaced with the central beam receiving member 740 adapted to the position of the vent 652 of the building, and the remaining column body members 730 and the column base member 720 can be dealt with by assembling the main column 700 using a common one. If the anchor bolt mounting position for fixing to the foundation 30 of the column base member 720 is different, only the column base member 720 is replaced with a column base member 720 that matches the anchor bolt mounting position of the building. The remaining central beam receiving member 740 and the column main body member 730 can be handled by assembling the main column 700 using a common one. Since the main pillar 700 can be configured by combining the three members in this way, it is possible to easily cope with a building having a different structure of the vent 652 or the position of the anchor bolt by replacing only the corresponding member. Can do. Furthermore, since it is possible to cope with a combination of three members, it is not necessary to prepare all types of main pillars 700 in advance, compared to the case where all of the main pillars 700 are integrated with steel, so there is no waste and the total number of parts Can be reduced.

In the present embodiment, as shown in FIG. 5, one end of the first beam member 820 is fixed to the center beam receiving member 740, and one end of the second beam member 840 is fixed to the second beam receiving member 830. Yes. Therefore, the structure of the central beam receiving member 740 can be simplified and the central beam can be simplified as compared with the case where all the beams 800 of the first beam member 820 and the second beam member 840 are gathered in the central beam receiving member 740. The size of the receiving member 740 can be reduced.
Further, as shown in FIG. 5, the first beam member 820 and the second beam member 840 are not fixed to the beam connector 73 but fixed by the first beam receiving member 810 at an intermediate position of the beam frame member 52. Yes. If the beam 800 of the first beam member 820 and the second beam member 840 is fixed by the beam connector 73, the beam 800 (the first beam member 820 and the second beam member 840), the beam frame is attached to one point of the beam connector 73. The member 52 and the frame member 50 of the other triangular structure 40 are concentrated, and the load on the beam connector 73 is increased. As a result, the beam connector 73 is enlarged in terms of strength, and the structure of the beam connector 73 is complicated in order to support the beam 800 (the first beam member 820 and the second beam member 840). . In the present embodiment, the beams 800 of the first beam member 820 and the second beam member 840 are not fixed to the beam connector 73 but are fixed by the first beam receiving member 810 at the intermediate position of the beam frame member 52. Thereby, the load applied to the beam connector 73 can be dispersed to reduce the load burden, and the beam connector 73 can be reduced in size and simplified. As a result, the structural stability of the dome-like structure 10 as a whole can be increased.
