Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower part support device for a relative displacement permitting partition installed in a room which causes horizontal relative displacement between a ceiling and a floor during an earthquake or the like.

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a partition structure of the type which allows relative displacement described in JP-A-3-202531 and JP-A-3-202532. The relative displacement allowance type partition described in both of the above publications has a schematic structure shown in FIG. 14, and the partition A is provided in one direction.
And a partition B provided in a direction perpendicular to the panel are mounted on a pillar 3 which is erected at a distance between a floor rail 1 attached to the floor and a ceiling rail 2 attached to the ceiling. It has a basic partition structure for mounting 4. The first characteristic of the partitions A and B of the relative displacement permissible type is the mounting structure of the floor rail 1 and the ceiling rail 2 and the pillars 3 standing on them. The lower end of the ceiling rail 2 is tiltable in the direction perpendicular to the surface of the panel 4, and the ceiling rail 2
On the other hand, the upper end of the support column 3 is tiltable in the direction perpendicular to the surface of the panel 4 and movable in the surface direction of the panel 4.

Therefore, in the case of horizontal relative displacement in the direction of the arrow shown in FIG. 14 between the floor rail 1 and the ceiling rail 2 due to an earthquake or the like, for the partition A, the upper end of the support column 3 is a panel. 4 in the plane direction, that is, along the ceiling rail 2, and with respect to the partition B, the upper and lower ends of the columns 3 tilt relative to the floor rail 1 and the ceiling rail 2 in the direction perpendicular to the plane of the panel 4, The relative displacement in the horizontal direction is allowed to prevent damage to the partition, floor, ceiling structure and the like. Although the example shown in FIG. 14 is described only for displacement in one direction, it is obvious that it is possible to cope with any relative displacement in the horizontal direction.

The relative displacement allowable partitions A and B
The second feature of partition A and partition B
It is the structure at the intersection with. That is, in FIG. 14, the panel 4 closest to the partition A of the partition B stays at a position spaced apart from the partition A, and the remaining space is hinged to the partition A side. It is arranged along both sides of panel B of B to close the gap to form a partition at the intersection, and automatically opens to the partition A side at the time of an earthquake, and the relative displacement of partitions A and B at the intersection. The parting panel 5 that forms the permissible space is installed. As described above, the column 3 of the relative displacement permitting partition has the lower end of the column 3 tiltable with respect to the floor rail 1 in a direction perpendicular to the surface of the panel 4, and the column 3 with respect to the ceiling rail 2. Since the upper end is tiltable in the direction perpendicular to the plane of the panel 4 and movable in the direction of the plane of the panel 4, relative displacement such as proximity, separation, inclination, etc. between the partitions may occur at the intersection of the partitions during an earthquake. In order to occur, the above-mentioned means for permitting relative displacement at the intersection is essential.

In the relative displacement allowance type partition constructed as described above, the support of the lower end portion of the column 3 to the floor rail 1 described in the above-mentioned publications is as shown in FIGS. 12 and 13. In addition, a lower bracket 6 including a supporting metal member 7 and a tilting member 8 between the floor rail 1 and the column 3.
The support member 9 and the mounting member 10 are interposed therebetween. The supporting metal member 7 of the lower bracket 6 has a lower portion formed as a substantially inverted U-shaped portion 11, and a panel locking hook 12 is formed on the upper portion thereof. Engage as shown. The tilting member 8 has a substantially inverted U-shaped portion 11 of the support metal member 7 inserted therein, a semi-cylindrical sliding surface 13 on the outer surface, and a pin 14 protruding from the semi-cylindrical end surface. And
Further, a locking claw 15 that is locked to the side surface through hole 3b of the column 3 is provided, and by locking the locking claw 15, the entire lower bracket 6 is locked to the column 3. In the U-shaped frame of the attachment member 10 fixed to the floor rail 1, the support member 9 is fitted and locked. The receiving and supporting member 9 has a box shape in which an engaging surface 16 on which the sliding surface 13 of the tilting member 8 slides is formed, and a groove hole 17 corresponding to the pin 14 is formed. The sliding surface 13 of the tilting member 8 is engaged with the engaging surface 16 of the receiving and supporting member 9, and the pin 14 of the tilting member 8 is engaged with the groove hole 17 of the receiving and supporting member 9, so that the support column 3 is formed. The floor rail 1 can be tilted.

Although the lower supporting device of the relative displacement permitting partition achieves the intended purpose, it has since been found to have the following problems. A. The substantially inverted U-shaped portion 11 of the supporting metal member 7 is likely to be deformed in a lateral direction by the load of the support column 3, and when such deformation is caused, the tilting member into which the substantially inverted U-shaped portion 11 is inserted. 8 is also affected by the deformation, and along with the deformation of the substantially inverted U-shaped portion 11, the sliding surface 13 of the tilting member 8 also deforms laterally. Therefore, the sliding surface 13 is in a tightly fitted state with the engaging surface 16 of the receiving and supporting member 9 to be engaged, and the tilting is not smoothly performed. In order to prevent such deformation, the supporting metal member 7 and the tilting member 8 must be made thick and have high strength. However, as the material cost rises, particularly the substantially inverted U-shaped portion 11 of the supporting metal member 7 is required. Pressing is quite difficult to obtain the correct shape. B. The support member 9 is an attachment member 10 fixed to the floor rail 1.
Since it is designed to be fitted and locked in the U-shaped frame of
There are many parts and it takes time to install. Further, when there is an obstacle for fixing the mounting member 10 directly below the support column 3, it is inconvenient because fixing means such as screwing cannot be used. C. Since the pin 14 of the tilting member 8 is directly provided on the tilting member 8, it is difficult to engage the pin 14 of the tilting member 8 with the groove hole 17 of the receiving and supporting member 9 or to release the pin 14 from the engaged state.

By locking the locking claw portion 47 in the locking through hole 29, the synthetic resin covering member 40 presses the metal skeleton member 31 having the insertion projecting edge 37 inserted thereinto to the column 25 side. Since it is locked to the pillar 25 in a shape, the pillar 25, the metal skeleton member 31, and the synthetic resin covering member 40 are in a state where the integrity is maintained despite the locking by a single locking means. Since they can be maintained, it is possible to prevent accidental disengagement of these members from the column 25.

On the other hand, when the pedestal member 50 is fixed at a predetermined position in the groove of the floor rail 20 and the pillar 25 is erected,
The pair of spring-like shaft protrusions 43 of the synthetic resin covering member 40 attached to the support column 25 are inserted into the box body 52 of the pedestal member 50 in a pushed-in state, and the spring-like shaft protrusions 43 are expanded and engaged. The semi-cylindrical tilting surface 41 of the synthetic resin coating member 40 is placed on the arcuate bearing surface 51 of the pedestal member 50 while being engaged with the mating groove 54. Although not shown, it is needless to say that a predetermined upper support device for a support is installed on the top of the support 25 when the support 25 is erected. As shown in FIGS. 1 and 2,
When the partition is assembled, the legs 34 of the metal frame member 31
The panel support hook portion 36 projecting from the panel 58 is used when the panel 58 is attached by being inserted and locked in the panel lower locking hole 59 provided inside the side edge portion of the panel 58. When the pillar 25 is erected and the partition is completed, the pedestal member 50 of the support member 30 is fixed in the groove of the floor rail 20 as shown in FIGS. The semi-cylindrical tilting surface 41 of the synthetic resin covering member 40 of the supporting member 30 attached to the above is mounted on the arcuate bearing surface 51 of the pedestal member 50 so as to be tiltable and incapable of slipping out.

Therefore, in the event of an earthquake, the floor rail 2

A metal skeleton member having an insertion projecting edge projecting downward from the central portion and having a flat bottom wall, and a leg portion projecting outward from the upper part fitted to the lower end of the column, and the metal skeleton member. The inserting projection edge is inserted into the inside, the abutting portion with which the planar bottom wall abuts is integrally formed with the peripheral wall, and the lower part has a semi-cylindrical tilting surface and the semi-cylindrical tilting surface. On both end surfaces of the semi-cylindrical tilting surface, a pair of spring-like shaft projections projectingly provided at the center of the semi-cylindrical tilting surface and the elastic synthetic resin covering member are in contact with the semi-cylindrical tilting surface of the synthetic resin covering member. A pedestal member that is mounted in the groove of the floor rail and that has a box body having a pair of engaging grooves that are formed in contact with the corresponding arcuate bearing surfaces and that engages the pair of spring-like shaft protrusions. The pillar has a rectangular tubular shape in cross section, and a rectangular notch is formed in both opposite walls at one end at its lower end. Locking through holes are formed in the other opposing walls, and four legs are formed in the legs of the metal skeleton member so as to be inscribed and fitted to the side edges of the notches. The synthetic resin covering member has a pair of locking claw portions which are expanded at the time of fitting and which are locked to the both locking through holes, at an upper part of the semi-cylindrical tilting surface side, The contact edge portion of the leg in the metal frame member having the insertion projecting edge inserted into the synthetic resin covering member is fitted into the notch portion of the column, and a pair of the synthetic resin covering member is provided. 2. A lower support device for a relative displacement permitting partition, characterized in that the locking claws of the above are locked in both locking through holes of the column.
