It is a figure seen from the direction shown by the arrow b of 1.

As shown in FIG. 2, the suspension structure 1 is provided in ISS4, which is an equipment space above a predetermined floor 3 of a building, and supports suspension of equipment installed in ISS4. The suspension structure 1 is composed of a suspension member 11, a lower chord member 12, a brace 13, a panel 14, and the like. The above equipment is installed on the panel 14, but the illustration is omitted in FIGS. 1 and 2.

The building is, for example, a production facility, and the predetermined floor 3 is used as a manufacturing area including a work room and the like by installing wall panels (not shown) and the like. However, its use, configuration, structural form, etc. are not particularly limited.

The hanging member 11 supports the panel 14 from the steel beam 2 (structure) of the roof of the building, and a plurality of hanging members 11 are arranged in a grid pattern on a flat surface. In the present embodiment, the upper end portion of the hanging member 11 is pin-joined to the steel frame beam 2 by a bolt or the like, and the hanging member 11 is provided in the vertical direction so as to extend downward from the steel frame beam 2. Shaped steel such as H-shaped steel can be used for the hanging material 11.

The lower chord member 12 is horizontally bridged between the intermediate portions of the adjacent hanging members 11. Various steel materials can be used for the lower chord member 12, and both ends thereof are pin-joined to the intermediate portion of the hanging member 11 by bolts or the like.

The brace 13 is provided in a vertical plane between adjacent hanging members 11. The brace 13 is inclined with respect to the horizontal direction, and two braces 13 are arranged in an X shape between adjacent hanging members 11. The upper end of the brace 13 is attached to the upper end of one hanging member 11, and the lower end of the brace 13 is attached to the middle of the other hanging member 11. The upper end and the lower end of the brace 13 are attached to the plate provided on the hanging member 11 by pin-joining them with bolts or the like.

As a result, in the present embodiment, the brace 13 is arranged only in the upper part between the adjacent hanging members 11, and in the lower part, a space without the brace 13 is secured on the panel 14, for example, about 2 m.

In the present embodiment, a core portion 10 (see FIG. 1) in which the lower chord member 12 and the brace 13 are arranged in a square square shape between the hanging members 11 which are vertically and horizontally adjacent to each other is formed. A plurality of core portions 10 are arranged at intervals in the vertical and horizontal directions of a flat surface, and a lower chord member 12 and a brace 13 are not provided between the hanging members 11 of the adjacent core portions 10.

The panel 14 has a strength that allows a person to walk, and is formed as a module combined with equipment installed on the panel 14. The panel 14 is attached to a mounting portion provided at the lower end of the hanging member 11.

FIG. 3A shows the mounting portion 110. The mounting portion 110 is configured by providing a mounting plate 112 on the lower surface of the upper plate 111 mounted on the lower end portion of the hanging member 11.

The panel 14 has a face material 141 formed of a steel plate or the like and a base material 142 made of a steel material such as a channel material. The flat surface of the face material 141 is rectangular, and the base material 142 is arranged in a substantially square shape along the outer peripheral portion of the upper surface of the face material 141 (see FIGS. 5 and 6 described later). In the mounting portion 110, the base material 142 is fastened to the mounting plate 112 by bolts 15 and the like.

FIG. 3B is a view of the mounting portion 110 as viewed from below. In the present embodiment, the mounting plates 112 have a flat L-shape, and four mounting plates 112 are arranged side by side so as to abut the corners. Then, the base material 142 (see the dotted line) at the corner of the plane of the four panels 14 is attached to each attachment plate 112. A sealing material 16 made of silicon or the like is provided between the adjacent panels 14.

However, the shape and arrangement of the mounting plates are not limited to this, and differ depending on the arrangement of the panels 14. For example, the mounting portion 110a of FIG. 4A is an example of mounting the base material 142 on the outer peripheral portion of the three panels 14, and two L-shaped mounting plates 112 and one linear mounting plate 112a are provided. Further, the mounting portion 110b in FIG. 4B is an example of mounting the base material 142 on the outer peripheral portion of the two panels 14, and two linear mounting plates 112a are provided. As described above, the shape and arrangement of the mounting plates are not particularly limited as long as the outer peripheral portions of the plurality of panels 14 can be mounted.

FIG. 5 is a diagram showing a construction method at the time of new construction of ISS4. In the present embodiment, during the construction of the building, the panel 14 in which the equipment 20 is integrated is assembled at the floor level as shown in FIG. 5 (a), lifted up as shown by the arrow, and shown in FIG. 5 (b). As described above, the panel 14 is attached to the lower end of the hanging member 11 as described above. Then, equipment 20 such as ducts and pipes on adjacent panels 14 are connected. In this embodiment, since the installation work of equipment, which is usually aerial work, can be performed at the floor level, safe and quick construction is possible.

In addition to ducts and pipes, the equipment 20 on the panel 14 includes a HEPA blowing unit, a lighting fixture, a utility panel, a cable, and the like, and these are modularized together with the panel 14. The utility panel supplies utilities such as power supply, water, compressed air, and steam.

The arrangement of these equipment 20 is appropriately determined. For example, in the case of a lighting fixture, a utility panel, a HEPA blowing unit, etc., as shown in FIG. 6, a plurality of panels 14 having the same vertical and horizontal sizes of these equipment 20 In ISS4, lighting equipment, utility panels, HEPA blowing units, etc. are arranged at equal pitches in the vertical and horizontal directions of the plane by fixing them to the face material 141 at the same plane position and arranging these panels 14 side by side. can do.

Note that 21 in FIG. 5B is a connecting portion in which ducts are connected as equipment 20 on adjacent panels 14, and the connecting portion 21 is located at a position corresponding to, for example, a boundary portion between the panels 14. 22 in FIGS. 5A and 5B is a support material for supporting the equipment 20 such as a duct, but the equipment 20 is supported from the lower chord member 12 between the hanging members 11, or under the lower chord member 12. In some cases, the equipment 20 is supported by a horizontal member added separately between the hanging members 11.

The panel 14 can be removed from the hanging member 11 and relocated freely. For example, when the ISS 4 is partially repaired, the panel 14 may be removed and relocated / replaced, and the panel 14 can be freely rearranged / added.

If the ISS4 is updated or significantly changed, the panel 14 integrated with the equipment 20 can be assembled at the manufacturing factory, and then the panel 14 can be transported to the site, lifted up at the site, and constructed. This method makes it possible to carry out on-site construction in a short period of time.

According to the present embodiment described above, the horizontal force of the panel 14 is transmitted to the steel beam 2 of the roof by the suspending material 11, and at this time, the brace 13 secures the earthquake resistance of the ISS 4 and the brace 13 is used. Is provided only on the upper part of the ISS4, so there are few restrictions on the placement space of the equipment 20, ducts and piping routes can be arranged in an orderly manner, and a safe passage space for maintenance etc. is secured, which is sufficient for repairs. A work space can be secured.

In order to realize seismic resistance, it is conceivable to make the panel 14 a so-called rigid ceiling that can bear the horizontal force, but it is difficult to realize it with the current face material 141 itself, and the panel 14 needs a reinforcing material such as a horizontal brace. As a result, the layout of the equipment 20 installed on the panel 14 becomes more restricted. However, in the present embodiment, the structure of the hanging member 11 that transmits the horizontal force of the panel 14 to the steel beam 2 of the roof and the brace 13 on the upper part of the hanging member 11 realizes the same seismic resistance as the case of the rigid ceiling. At the same time, equipment can be installed freely. In addition, since these members are also pin-joined with bolts or the like, construction is easy.

Further, in the present embodiment, the braces 13 are integrated as the core portion 10, and the core portions 10 are regularly arranged at intervals in the vertical and horizontal directions, so that the equipment 20 such as ducts and pipes can be used between the core portions 10. The placement space of can be maximized. Further, the braces 13 can be provided in at least two directions for all the hanging members 11, and the seismic resistance of the ISS 4 can be suitably ensured.

Further, by mounting the outer peripheral portions of the plurality of panels 14 to the mounting portion 110 of the hanging member 11, the plurality of panels 14 can be supported by one hanging member 11, and the number of the hanging members 11 can be reduced.

Further, in the present embodiment, a module (unit) in which the panel 14 and the equipment 20 installed on the panel 14 are integrated is adopted. By installing the equipment 20 on the panel 14 on the ground, lifting it up and attaching it to the hanging material 11, and connecting the equipment 20 such as ducts and pipes of the adjacent panels 14, it is easy and in a short period of time. Construction is possible, and when the equipment 20 is rearranged, the panel 14 can be replaced to enable speedy change.

However, the present invention is not limited to this. For example, in the present embodiment, the flat square-shaped core portion 10 is formed, but the brace 13 on one side is omitted, and the flat U-shaped core portion 10a is formed as shown in FIG. May be good. In this case, the X-shaped brace 13a is attached in the horizontal plane at a height corresponding to the intermediate portion of the hanging member 11. However, by arranging the core portion 10 as in the present embodiment, the minimum amount of steel material is required, and the brace 13a in the horizontal plane becomes unnecessary, so that the equipment 20 can be easily arranged.

Further, although the hanging member 11 is attached to the steel beam 2 of the roof, the structure for attaching the hanging member 11 is not limited to this, and the hanging member 11 can be attached to a slab or the like on the ceiling. Further, the face material 141 of the panel 14 is not particularly limited, and may be a corrugated plate or the like.

Although preferred embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications or modifications within the scope of the technical idea disclosed in the present application, and these also naturally belong to the technical scope of the present invention.
