Field of the Invention The present invention relates to a structure for suspending a panel from a ceiling, and more particularly to a structure for suspending a panel from a ceiling in a clean room, a large refrigerator or a freezer, an electromagnetic shielding room, or a normal building. is there.

[0002]

2. Description of the Related Art Generally, a panel constituting a clean room is required to have heat insulating properties and light weight. Therefore, a heat insulating core material such as foamed polyurethane is filled between a pair of surface plates, and a frame material is provided around the core material. A so-called sandwich structure equipped with a is often used.

[0003] When the panel constructed as described above is used as a ceiling panel, a suspension for mounting and fixing the panel to a ceiling rail suspended from suspension bolts suspended from a ceiling slab via a fixture is used. The structure is generally known. As this ceiling suspension structure, for example, as shown in FIG. 5, an anchor member c having a crank-shaped cross section to which a nut b is fixed is embedded in a core material a, and a fixture e and a nut of the anchor member c are engaged with the ceiling rail d. b with a fixing bolt f, or, as shown in FIG. 6, outward wings h,
A structure in which a nut holding member j provided with i is embedded in a core material a, and a fixture e engaging with a ceiling rail d and a nut b arranged in a nut accommodating portion g are fixed with fixing bolts f. (See Japanese Utility Model Publication No. 63-15746). In addition, in FIG.5 and FIG.6, the code | symbol k is a surface plate and the code | symbol m is a frame material.

[0004]

However, in this type of conventional ceiling suspension structure, since both the anchor member c and the nut holding member j are buried in the core material a, the core material a is a surface plate. There is a disadvantage that it cannot be used for a panel in which a non-combustible or quasi-non-combustible core material such as a honeycomb core or a calcium carbonate foam material which is previously formed into a rectangular plate shape is pasted to the surface plate. . In addition, the anchor member c and the nut holding member j
The structure only buried in the inside is weak in strength, and there is also a problem that a worker cannot walk under the ceiling due to duct work or electric wiring work behind the ceiling.

The present invention has been made in view of the above circumstances, and can be applied to either the filling type or the sticking type of the core material of the panel. In addition to increasing the strength of the panel itself, it is possible to increase the strength of the panel itself and to attach it to the ceiling rail. It is an object of the present invention to provide a ceiling suspension structure of a panel for strengthening the panel.

[0006]

Means for Solving the Problems To achieve the above object, a panel ceiling suspension structure according to the present invention is a panel having a core material interposed between a pair of surface plates and a frame material attached around the core material. Assuming a ceiling suspension structure of a panel which is mounted on a ceiling rail via a fixture, the panel is cut between both surface plates around the mounting side of the panel while being in contact with both surface plates. A rectangular rectangular hollow reinforcing material is interposed, a mounting seat is provided on the lower surface of the top of the hollow reinforcing material, and the mounting tool and the mounting seat are fixed with fixing bolts. .

In this invention, the mounting seat may be fixed to the lower surface of the hollow reinforcing member by welding or the like as long as it is attached to the lower surface of the hollow reinforcing member having a rectangular cross section. However, it is preferable to provide a mounting groove on the inner surface of both side walls of the hollow reinforcing member, and to insert and fix a mounting seat in the mounting groove. In this case, the mounting groove may be provided on the side wall of the hollow reinforcing member, or may be formed by an inner surface of the side wall and a ridge protruding from the inner surface of the side wall.

The form of the hollow reinforcing member may be arbitrary as long as it is interposed between both surface plates in the peripheral portion on the mounting side of the panel, but preferably the upper and lower portions of the outer surface of the side wall of the hollow reinforcing member. It is preferable to protrude the upper horizontal piece and the lower horizontal piece from each other, and to clamp the sleeve of the frame material between the upper horizontal piece and the lower horizontal piece and the surface plate.

The mounting seat may be of any shape as long as it is attached to the lower surface of the top of the hollow reinforcing member.
Preferably, the mounting seat is made to protrude from the hollow reinforcing member, and the sleeve of the frame material is sandwiched between the projecting portion of the mounting seat and the surface plate.

[0010]

According to the panel suspension structure of the present invention constructed as described above, a hollow reinforcing member having a rectangular cross section is interposed between both surface plates in the peripheral portion on the mounting side of the panel. By attaching a mounting seat to the lower surface of the top of the panel and fixing the mounting fixture and the mounting seat with fixing bolts, the strength of the panel itself can be increased, and the panel can be connected to the ceiling rail through the mounting fixture. It can be installed firmly on the ceiling rail. Further, since it is not necessary to embed the hollow reinforcing material in the core material, the hollow reinforcing material can be applied to any of panels in which the core material is filled between the surface plates and panels to which the surface plate and the core material are attached.

[0011] Further, by providing a mounting groove on the inner surface of both side walls of the hollow reinforcing member, and fitting and fixing the mounting seat in the mounting groove, the mounting seat can be easily and firmly attached to the hollow reinforcing member.

An upper horizontal piece and a lower horizontal piece are protrudingly provided at the upper and lower portions of the outer surface of the side wall of the hollow reinforcing member, and a sleeve of the frame is sandwiched between the upper horizontal piece and the lower horizontal piece and the surface plate. By doing so, the frame member can be firmly attached.

Also, the mounting seat is projected from the hollow reinforcing material,
By sandwiching the sleeve of the frame material between the projection of the mounting seat and the surface plate, the frame material can be firmly mounted.
