Description

  The present invention relates to a hanging structure of a partition panel having a high height of, for example, several meters.

  A partition device is used to partition a large space in a building, and the partition device is arranged with vertically standing panels, and each panel is placed on a baseboard attached via an adjuster on the floor rail. Both ends are connected to a vertically standing stud, and the upper end is an installation structure that is restrained by a ceiling rail. The panel disposed between the studs may have a single panel structure or may be disposed on both sides, but any panel mounting structure is placed on the baseboard.

  FIG. 4 shows a longitudinal section of a conventional partition device. The panel (A) has a paper core (B) as a core material, and surface materials (C) and (C) are stuck on both sides, and is supported on a baseboard (D). The upper end of the panel (a) is fitted into a ceiling rail (e) having a substantially gate-shaped cross section so that no gap remains between it and the ceiling panel (f). By the way, the panel (A) is connected to the studs standing upright on both sides so that the panel (A) does not fall down, but compressive stress acts on the panel (A) placed on the baseboard (D).

  As shown in the figure, the compressive stress σ acting on the panel cross section is small at the upper end of the panel, but larger at the lower end. In a general office partition device, the panel height is about 3 m, so the magnitude of the compressive stress σ is not so large, but if the panel height is several meters or more, it becomes very large. The paper core (b) serving as the core material is strong against the compressive force from both sides, but the resistance to the external force in the vertical direction is relatively weak, and the effect as a reinforcing material for the panel (b) is small.

  Therefore, a buckling phenomenon occurs when a pressing force is applied from one side or when a roll such as an earthquake occurs. That is, since a bending stress due to a pressing force from one surface is applied in a state where a large compressive stress is applied, the panel (A) is easily buckled. Of course, this can be dealt with by increasing the strength of the frame that is the frame of the panel so as not to buckle. However, as a result, the weight increases and the manufacturing cost increases due to an increase in material costs.

On the other hand, there is also a method of hooking on a stud standing up via a claw as a panel installation structure. For example, in “Panel Connection Plate Receptor and Partition Panel” according to Japanese Utility Model Laid-Open No. 4-127306, panel holders (claws) are provided on both sides of the panel, but a large, tall panel is attached to the stud via the claw. The hooking work is not easy. In other words, since the claws are attached to a plurality of positions on the panel side end, it is difficult to fit all the claws into the latching grooves formed in the studs. Also, in order to support a large panel through the claw, the claw must be strong enough to support the panel, and the load does not act evenly on all the claw, and some claw It will be broken.

  As described above, the partition device for installing the partition panel having a high height has the above-described problems. The problems to be solved by the present invention are these problems, and provide a hanging structure of a partition panel that can be installed so as not to cause a buckling phenomenon even in a large panel having a high height.

  The panel installation means of the present invention has a structure in which it is suspended from the ceiling instead of being placed on a baseboard. Here, the specific hanging structure of the panel is not limited, and the panel can be hooked on the ceiling key of the ceiling rail attached to the upper end of the panel and fixed to the ceiling beam. It is also possible to directly fix the upper end of the panel to the ceiling rail fixed to the ceiling beam by bolting. And the panel which hung the upper end on the ceiling rail is made into the structure which inserts and restrains in the floor rail laid on the floor surface because the lower end is unstable.

  The panel suspension structure of the present invention is configured so that the upper end of the panel is suspended from the ceiling beam. Therefore, even tall panels of several meters or more can be installed without causing buckling, and there is no need to increase the panel strength. Can be hung without any problems. Therefore, the manufacturing cost is reduced because a large panel strength is not required, and the installation work is facilitated because the panel weight is reduced. And since the panel is suspended, the panel will not fall over even if a pressing force acts on the panel surface or an earthquake occurs and rolls. There is no need to bend. On the other hand, since a floor rail having a substantially U-shaped cross section is provided on the floor and the lower end of the panel is fitted and restrained, the panel does not roll and is stable.

  FIG. 1 shows the appearance of a clean room constructed using the panel suspension structure of the present invention. In the clean room, a plurality of panels 1, 1... Are suspended from ceiling beams 2, 2. The clean room itself is a conventional one, but the ceiling height of the clean room is high and is several meters or more, and it is not a structure in which the panel 1 is placed on the baseboard as it is, but the panel 1 has a burden. It has a structure that hangs from the ceiling so as not to be applied.

  Of course, the panel suspension structure of the present invention is not limited to a clean room as shown in the figure, and can be freely adopted as a panel suspension structure of a general partition device that can partition a large building space. 2 shows an enlarged cross-sectional view taken along the line AA of FIG. 1, a panel key 3 is attached to the upper end of the panel 1, and is suspended on a ceiling rail 20 having a substantially portal-shaped section fixed to the ceiling beam 2. It is installed. A ceiling key 4 is provided on the ceiling rail 20, and the panel key 3 is locked to the ceiling key 4.

  The ceiling rail 20 is a long material having a predetermined cross section, and is fixed along the lower surface of the ceiling beam 2, and one panel key 3 is not limited to being formed over the entire panel width, but can be provided only on both sides. A hanging piece 5 extends downward from the ceiling key 4 to reach the upper end of the panel 1, and the lower end of the hanging piece 5 is in contact with the surface. In addition, a sealing material 6 is fitted into a concave groove formed inside the lower end portion of the hanging piece 5, and the sealing material 6 eliminates a gap with the panel 1. That is, the clean room has a structure in which intrusion of outside air is blocked.

  A cover 7 is attached to the ceiling rail 20 so as to face the ceiling key 4, and the cover 7 extends downward until it reaches the upper end of the panel so as to have the same appearance as the ceiling key 4 and the hanging piece 5. Therefore, the upper end portion of the panel 1 has a structure sandwiched between the hanging piece 5 and the cover 7. However, the seal is not fitted in the concave groove formed inside the lower end of the cover 7. Locking pieces 8, 9 extend horizontally at a predetermined interval on the cover 7, and the locking pieces 8, 9 are fixedly attached to locking grooves 10, 11 formed in the ceiling key 4. It has been. The cover 7 can be attached after the panel 1 is suspended from the ceiling key 4, and the panel key 3 and the ceiling key 4, which are the suspended structure of the panel 1, are covered from the outside.

  By the way, the panel key 3 provided at the upper end of the panel is positioned on the neutral surface of the panel 1, the weight balance is maintained so that the suspended panel 1 does not shake, and the upper surface is opened in a generally U shape. A cross-section floor rail 12 is laid, and a lower end of the panel is fitted in a space 13 of the floor rail 12. Therefore, since the lower end of the panel is fitted and restrained on the floor rail 13, the roll of the panel 1 suspended through the panel key 3 is prevented.

  Therefore, the lower end portion of the panel is sandwiched between both side pieces 14 and 14 of the floor rail 12, and a concave groove is formed inside the outer side piece 14, and a sealing material 6 is fitted in the concave groove. . Since the sealing material 6 is in contact with the surface of the lower end of the panel, the intrusion of outside air is blocked and functions as a clean room.

  In the present invention, since the upper end of the panel 1 is suspended as described above, a tensile stress acts on the panel 1. The tensile stress is large on the upper end side of the panel and smaller on the lower end side. In other words, it is like hanging a curtain, and even if the strength of the panel 1 is small, it can be hung straight, and even a thin panel can function sufficiently as a partition panel. Does not occur.

  FIG. 3 is an embodiment showing another suspended structure according to the present invention. A ceiling rail 15 having a substantially gate-shaped cross section with an opening on the lower side is fixed to the ceiling beam 2 by bolting. The upper end of the panel 1 is fitted in the space 16 of the ceiling rail 15 and side pieces 17a and 17b It is bolted to. Therefore, the panel 1 is suspended from the ceiling rail 15, and the lower end portion is sandwiched between the side pieces 19 and 19 of the floor rail 18.
