Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIGS. 1 and 2, the membrane ceiling panel with a protective plate according to the embodiment of the present invention is attached so as to cover the membrane ceiling panel 1 and the membrane material 12 stretched on the frame 11 of the membrane ceiling panel 1. The protective plate 2 is formed. The protective plate 2 is temporarily fixed to the membrane ceiling panel 1, and the membrane ceiling panel 1 can be fixed to a field edge which is a ceiling base (not shown) in a state where the protective plate 2 is temporarily fixed, and after the fixing, The protective plate 2 can be removed from the membrane ceiling panel 1. The protective plate 2 may be disposable or may be used repeatedly.

  The membrane ceiling panel 1 can be formed in, for example, a square having a length and width of 910 mm, but is not limited to such a shape. Moreover, if it forms in the same dimension as the existing plaster board ceiling panel, a field edge can be arrange | positioned and the said membrane ceiling panel 1 can be attached similarly to the conventional field arrangement work.

  The frame 11 is made of, for example, a lightweight steel frame, an aluminum alloy extruded product, a wood material, etc., and may be solid or hollow. The frame 11 can be manufactured by, for example, combining four frame members having the same shape into a square.

  The film material 12 is adhered to the lower surface (front surface) side of the frame 11 by applying an adhesive to the bonding margin 12a at each edge. Of course, the film material 12 may be bonded to the outer surface (vertical surface) of the frame member of the frame 11, or may be bonded to the back surface or inner surface (vertical surface) of the frame member around the outer surface. Good. Moreover, not only adhesion | attachment but you may make it latch the edge part of the film | membrane material 12 with a crimping member.

  As the film material 12, for example, a glass fiber resin sheet obtained by coating a non-stretchable glass fiber fabric with a fluororesin or a silicon resin, a sheet made of a glass cloth base fabric and an acrylic resin composite material, or the like may be used. it can.

  In this embodiment, a sheet having elasticity is used as the film material 12. Examples of such stretchable sheets include polyester sheets and knitted fabrics. Further, in this embodiment, the film material 12 is attached to the frame 11 with tension applied in one direction. One or more cuts 12b are formed in the direction of the tension. The degree of the tension is set so that the gap 12b is not pulled by the tension to generate a gap. Such a cut 12b does not allow the user to recognize the presence of the cut 12b in the state as it is, but allows the user to widen the cut 12b by placing his / her hand. The size of the spread is such that a person can put his head and upper body.

  Further, for example, a zip tone pattern is printed on the surface of the film material 12. In the case of a ceiling structure in which a plasterboard ceiling panel having a ziptone pattern and the membrane ceiling panel 1 are mixed, for example, by printing on the membrane ceiling panel 1 a diptone pattern that matches the ziptone pattern of the plasterboard ceiling panel, It can appear as if the ceiling is made of a single material. Instead of printing, it is also possible to form a pattern consisting of irregularities on the film itself. In addition, as the film material 12, a material having no pattern or unevenness can be used.

  The protection plate 2 has, for example, a rectangular shape having the same dimensions as the membrane ceiling panel 1 and is made of a lightweight resin, metal, or woody board. For example, a corner portion of the protection plate 2 is formed with a first portion 21 for temporarily securing the protection plate 2 to the membrane ceiling panel 1 with a temporary fastening screw (temporary fastening member). A second portion 22 is formed at the peripheral edge portion of the second portion 22 so as not to interfere with the main fastening screw (fastening member) for fixing the membrane ceiling panel 1 to the field edge.

  The first portion 21 is formed of a hole having a diameter smaller than the head diameter of the temporary fastening screw, for example, and the temporary fastening screw is inserted into a screw hole (not shown) formed in the frame 11 through the hole. be able to. Note that eyelets may be provided at locations where the temporary fastening screws of the membrane material 12 are mounted. Further, a temporary fixing screw may be driven in place of the temporary fixing screw to temporarily fix it. On the other hand, the second portion 22 has an opening having a diameter larger than the head diameter of the main fastening screw, and the main fastening screw is screwed into the frame 11 of the membrane ceiling panel 1 through the opening. Yes. It should be noted that eyelets may be provided on the membrane material 12 where the main fastening screws are mounted.

  As the first portion 21, a magnet may be used instead of the hole. In this case, it is not necessary to attach a screw or a screw to the frame 11 or the film material 12, and the rotation work of the driver is performed. Can be omitted. If the frame 11 is not made of steel, a magnetic material may be embedded in the portion of the frame 11 that contacts the magnet. Instead of using all of the four first parts 21 as magnets, for example, three parts may be magnets and one part may be screwed.

  The second portion 22 may be formed with notches corresponding to one opening or a plurality of openings instead of the opening.

  FIG. 3 shows the membrane ceiling panel 1 with a protective plate and the air conditioner 3. Each membrane ceiling panel 1 has a U-shape in plan view, and a square space is formed in the center portion by combining two sheets, and the front portion of the air conditioner 3 is housed in the square space. A protective plate having the same U-shape is attached to the U-shaped membrane ceiling panel 1.

  In the membrane ceiling panel 1, a part of the frame 11 (cross-hatched part in FIG. 3) is easily deformed by an impact as compared with other parts. For example, (1) a structure in which a part of the frame 11 is movable by a hinge and can be restored to its original shape by a spring, and (2) a part of the frame 11 is a main body. And a structure in which the separation part is supported by a support structure part in which a restoring spring is inserted into a telescopic rod-shaped member made of multiple cylinders. (3) A part of the frame 11 is separated from the main body. A separated separation portion, and a structure in which the separation portion and the main body portion are connected and supported by an elastic body; (4) a structure in which a part of the frame 11 is formed using an elastic body such as rubber; and (5) the frame. A structure in which a part of 11 is formed using a flexible material such as sponge. (6) A part of the frame 11 is formed of wood such as a balsa material that is easy to break, hollow resin material, metal such as aluminum, and the like. That structure, is realized by a structure that forms a notch for imparting fracture deformation easiness in part of (7) above the frame 11.

  When the easily deformable portion of the frame 11 is not fixed to the field edge, it is not necessary to form the second portion 22 in the portion of the protection plate 2 that covers the easily deformable portion. In addition, in the part of the protection plate 2 that covers the easily deformable part, the first part 21 for temporarily securing the protective plate 2 to the membrane ceiling panel 1 is not formed, and in other parts that are not easily deformed. The first portion 21 may be formed.

  FIG. 4 schematically shows the ceiling structure according to the embodiment of the present invention. In this ceiling structure, a membrane ceiling panel 1 in which a part of the frame 11 is easily deformable and a ceiling panel 5 including a non-membrane material (hard material) such as a plaster board are mixed. In the figure, the cross-hatched portion shows the membrane ceiling panel 1, and the hatched portion shows the ceiling panel 5. In this example, a rectangular membrane ceiling panel 1 is disposed at the wall 6a of the building 6, and a bowl-shaped membrane ceiling panel 1 is disposed at the column 6b.

  Furthermore, in the ceiling structure, the membrane ceiling panel 1 is fixed to a field edge (not shown) with a portion where the frame 11 is easily deformed facing the wall 6a and the column 6b of the building 6. The protective plate 2 is removed from the membrane ceiling panel 1. In the ceiling structure, an air conditioner and a lighting device (not shown) may be attached in the arrangement area of the ceiling panel 5 using a general attachment method. On the other hand, in the region for such an air conditioner or lighting fixture, a portion of the membrane ceiling panel 1 where the frame 11 is easily deformed may be fixed facing the air conditioning device or lighting fixture. Good.

  If it is said structure, the protective plate 2 which covers the said film | membrane material 12 is temporarily fastened to the said membrane ceiling panel 1, and the said membrane ceiling panel 1 is a ceiling base | substrate in the state which the said protective plate 2 was temporarily fastened. Since it can be fixed to the field edge, the membrane material 12 is not distorted or soiled during transportation or attachment of the membrane ceiling panel 1.

  When the cut 12b is formed in the film material 12, when checking the back of the ceiling, an operator can perform various checks by spreading the cut 12b from the bottom of the ceiling and putting the head or the like into the back of the ceiling. This eliminates the need to remove the ceiling panel for inspection, and can greatly reduce the inspection cost. Further, the membrane ceiling panel 1 in which the cut 12b is formed in the membrane material 12 requires further care in handling. However, since the protective plate 2 is attached, the ceiling panel of a general plaster board The ceiling construction is possible even if it is not a skilled worker. Further, the membrane ceiling panel 1 having the cut 12b does not need to be arranged at all locations, and the cut 12b may be formed in the membrane ceiling panel 1 at a position close to the inspection location.

  In addition, the membrane ceiling panel 1 in which a part of the frame 11 is more easily deformed by impact than other parts requires more care in handling, but the protection plate 2 is attached. Thus, it can be handled in the same manner as a general plasterboard ceiling panel, and ceiling construction is possible even without a skilled worker.

  The portion of the membrane ceiling panel 1 where the frame 11 is easily deformed is positioned on the wall 6a or the column 6b of the building 6 or on the ceiling air conditioner or lighting fixture and fixed to the ceiling base. When the membrane ceiling panel 1 hits against the wall 6a or the like due to an earthquake, this portion absorbs an impact and deforms, so that the membrane ceiling panel 1 falls together and the membrane ceiling panel It is avoided that the ceiling panel 5 adjacent to the panel 1 falls in a chain with the fall of 1. In addition, such a structure becomes an earthquake countermeasure structure equivalent to the earthquake countermeasure structure in which a certain gap is formed between the wall 6a and the like of the building 6 and the membrane ceiling panel 1 is disposed, while the deformation is easy. Since the various parts fill the gap, the appearance of the ceiling is improved compared to the earthquake countermeasure structure that forms the gap. Further, the mixed structure of the membrane ceiling panel 1 and the ceiling panel 5 shown in FIG. 4 is easier to reduce in weight than the ceiling made of only the ceiling panel 5, and acts on the ceiling in the event of an earthquake. And the weight of the ceiling foundation are reduced, thereby further reducing the force acting on the ceiling and reducing the impact caused by the shaking of the earthquake. Furthermore, even if the membrane ceiling panel 1 is dropped, it is formed of a soft membrane except for the frame 11, so that it is less likely to cause serious harm than dropping of the non-membrane material.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
