Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a ceiling unit board,
It relates to ceilings that are attached to ceilings such as lighting fixtures, speakers, air conditioners, and sprinklers, and perform wiring and piping to supply them to them rationally.

[0002]

2. Description of the Related Art Electric wiring, communication wiring, ducts for air conditioning and ventilation, piping for sprinklers, etc. are installed in the ceiling of office buildings. Lighting equipment, speakers, air conditioning equipment, sprinklers, etc. are mounted on the ceiling surface.

With the spread of OA equipment, the ceiling is not enough, and the floor has a double structure and is used as electric wiring, communication wiring, and an air conditioning chamber.

In office buildings and the like, layout changes accompanied by partitioning of rooms are frequently performed due to organizational changes, personnel changes, changes in applications, and the like. As means for dealing with them, the present inventor has made the invention disclosed in Japanese Patent Laid-Open No. 4-118440. After that, regarding the installation of the ceiling unit board, "Supporting device for the ceiling unit (actual flat 6-3
0312) ”has been devised.

[0005]

However, the conventional ceiling unit is disadvantageous in construction cost because the construction of the ceiling underlay is complicated and the material is increased in comparison with the general system ceiling. That is, conventionally, the ceiling base material is basically attached in parallel along the wall of the room, etc., and is installed orthogonally to the vertical material horizontal member so that the base aggregate for attaching the ceiling unit is directly above the unit.

Further, there are two types of mounting brackets to be mounted on the ceiling unit body, and since the two types have directivity at the time of mounting, it is inconvenient for mass production and mounting of the mounting brackets on the panel. Furthermore, there was a problem in that it was necessary to be careful when installing the ceiling unit on site and to confirm the type of metal fitting when removing it.

[0008]

According to the present invention, a ceiling base is provided so as to be parallel to a diagonal of the ceiling unit when mounting the ceiling base aggregate of the ceiling unit. In other words, the main ceiling base aggregate has a diagonal angle with respect to the wall rather than “parallel to” the conventional wall. In the treatment of the joint with the wall, a secondary aggregate along the wall may be provided.

When mounting the structure, the ceiling bolts are attached to the inserts of the slab on the upper floor (mounting brackets driven into the slab into which the hanging hardware is screwed), and the aggregates are attached to this. Attach the mounting bracket of the ceiling unit to this aggregate. The tip engaging part of the ceiling unit mounting bracket is spherical, and there is no direction when mounting. Therefore, the engaging portion of the ceiling unit is embossed so as to engage with it.

The engaging parts attached to the ceiling unit face the ceiling unit mounting bracket at four corners. All four metal fittings have the same shape.

The size between the ceiling base aggregate and the ceiling unit is slightly larger than the height of a lighting fixture or the like attached to the ceiling unit.

In addition to the ceiling unit as the ceiling base aggregate, the supply pipes and wiring used in the room are used as the basis, and the outlets, telephone line outlets, and sprinklers installed on the ceiling are conventionally installed indoors. Install speakers, air conditioner outlets, intakes, etc. This gives the ceiling a much cleaner look. Of course, because of the nature of the ceiling, no inspection door is required.

Since the ceiling unit is attached by a metal fitting having an engaging structure that can be easily attached and detached, it is possible to simply install the ceiling unit by detaching the ceiling unit when a new required utility is newly installed or abolished when it is no longer needed.

The thing attached to the ceiling unit is convenient because, for example, a lighting fixture or the like can be moved together with the ceiling unit without damaging the ceiling.

[0015]

[Operation] When mounting the ceiling base aggregate of the ceiling unit,
Since the ceiling base is provided so as to be parallel to the diagonal line of the ceiling unit, it can be easily determined by the distance from the intersection when mounting the ceiling unit hanging device.

Since the main ceiling base aggregate is laid at a diagonal angle, various pipes arranged on the ceiling base are securely supported and no special support is required. However, there is no question that it is within the allowable load range of the ceiling base.

Since the engaging portion of the ceiling unit hanging device has a spherical shape, it has no directionality, and it is possible to deal with the ceiling unit having a non-square shape. This can be dealt with by relocating the ceiling unit engaging device even if one side of the ceiling unit is cut off in connection with the wall. The fact that there is no shape constraint increases the degree of freedom.

The ceiling base aggregate 8 is in contact with each wall at an angle. Of course, it is equivalent to make the ceiling base aggregate 8 parallel to the wall and make the ceiling unit at an angle to the wall.

FIG. 4 is a plan view of laying the ceiling unit 2 as seen in the direction of the arrow on the C-C cross section.
It is shown by a dotted broken line, and the ceiling unit 2 and the adjustment hanger 13 are shown. The width of the ceiling unit 2 in the Y direction is L, and the ceiling units 2 are attached at unit intervals S.

FIG. 5 is a detailed cross-sectional view of the AA cross section taken in the direction of the arrow. The ceiling unit 2 is suspended from the upper floor slab 9 by the ceiling bolts 10 to suspend the lower member of the ceiling base aggregate 8. The aggregate which is lowered and is on the upper side is bound and fixed by the wire 16. At this time, the same applies even if the suspended aggregate from the upper slab 9 becomes the upper aggregate. The ceiling unit 2 is suspended from each ceiling base aggregate 8 by a unit hanger 12. This suspension interval is w in the X direction.

FIG. 6 is a detailed plan view of the section taken along the line BB in the direction of the arrow. The hanging bolt 10 and the aggregate hanger 1 under the ceiling are used.
1 and the ceiling unit 2 is hung by the unit hanger 12. The ceiling base aggregate 8 is bound and fixed by a wire 16.

The length L of the ceiling unit 2 in the Y direction, the distance l between the engaging devices, and the distance S from the adjacent ceiling unit 2 are given. Similarly X
It is the length W in the direction, the distance w between the engaging devices, and the distance T from the adjacent ceiling unit 2.

FIG. 7 is a plan view and a side view of the ceiling unit 2. A direction is generated in the ceiling unit 2 by the panel engaging device 15 of the ceiling unit. The embossing engagement portion 17 of the panel engaging device 15 of the ceiling unit has an insertion end 18 and a closed end 19, and the insertion end 18 and the closed end 19 are in the Y direction, and the direction perpendicular thereto is the X direction. Therefore, the ceiling unit 2 can be attached and detached at the engaging portion in the Y direction,
It cannot be attached or removed in the X direction.

When mounting the panel engagement device 15, the same may be applied in the X direction, but in the Y direction, the insertion end 18 of the embossing engagement portion 17 is placed inside so as to face each other. Therefore, the closed ends 19 are each directed outward.

FIG. 8 is a detailed plan view of the panel engaging device 15. The embossing engagement portion 17 has an insertion end 18 and a closed end 19 in the X direction. The embossing engaging portion 17 has an engaging groove 21 in which the engaging bolt 14 engages with the slide groove 20 and the spherical engaging end 23 of the engaging bolt 14 in the X direction, and the central portion is further embossed.

The engaging groove 21 and the stop portion 22.

FIG. 11 is a front view of the ceiling unit fixture, FIG.
2 is the same side view. A unit hanger 12 is attached to the ceiling base aggregate 8 and an engaging bolt 14 is fixed to the adjusting hanger 13 with a nut 24. Since the tip of the engaging bolt 14 is formed into a spherical shape, it loses directionality when mounted.

FIG. 13 shows a state in which unit hangers 12 are attached to the ceiling base aggregate 8 laid parallel to the diagonal line of the ceiling unit 2 at intervals of w and l in the X and Y directions, respectively. An engagement bolt 14 is attached to the adjustment hanger 13. Since the ceiling base aggregate 8 is laid in a diagonal line, the position is uniquely determined from each intersection of the ceiling base aggregate 8. Therefore, both accuracy and speed at the time of construction are greatly improved.

FIG. 14 is a drawing of the first stage of suspending the ceiling unit 2, in which the spherical engaging end 23 of the engaging bolt 14 and the insertion end 1 of the panel engaging device 15 of the ceiling unit 2 in the Y direction.
8 is a state diagram in which 8 and 8 are in contact with each other. Although not shown, there are two locations in the W direction. At this time, the width W of the ceiling unit 2
If 1,200 mm or less, one person can work. The uncontacted side of the ceiling unit 2 is the operator's hand (not shown)
Therefore, it is supported.

FIG. 15 is a view of the second stage of suspending the ceiling unit 2, showing the spherical engagement end 23 of the engagement bolt 14 and the closed end 19 of the engagement device 15 of the ceiling unit 2 in the engaged state. . The operator's hand is just released while being just suspended by the engagement bolt 14.

FIG. 16 is a diagram of the third stage in which the ceiling unit 2 is suspended, and the side (lower side in the figure) of the ceiling unit 2 that is not in the engaged state from the second stage is the spherical engagement of the other engagement bolt 14. FIG. 6 is a state diagram in which the joint end 23 is lifted up.

FIG. 17 is a view showing that the ceiling unit 2 is hung up and the mounting of the ceiling unit 2 is completed in the fourth stage.
6 is a state diagram in which the spherical engagement end 23 of the engagement bolt 14 is engaged with the stop portion 22 at the center of the unit engagement device 15 by sliding. Since this stop portion 22 is embossed, it is fixed at this position.

After the completion of the mounting in the fourth stage, a horizontal external force acts on the ceiling unit 2 so that the ceiling unit 2 slides and is disengaged from one of the engaging devices 15, but the rest is in an engaged state and falls to the floor. There is nothing to do. Therefore the ceiling unit 2
Is not damaged. The detachment due to this external force is determined by the size of the embossment of the stop portion 22.

When the ceiling base aggregate 8 of the ceiling unit 2 is mounted, the ceiling base is provided so as to be parallel to the diagonal line of the ceiling unit 2. Therefore, when mounting the ceiling unit 2, it is easily determined by the distance from the intersection. Furthermore, since the ceiling base aggregate 8 is laid at a diagonal angle,
Various pipes arranged on the ceiling base are securely supported and no special support material is required.

Since the tip of the engaging bolt 14 is the spherical engaging end 23, it has no directivity. This increases the degree of freedom and increases the efficiency during manufacturing and construction.
