Description

  The present invention relates to an optical film ceiling mounting structure, and more particularly to an optical film ceiling mounting structure in which a shade film material for ceiling lighting can be easily attached and detached.

  Conventionally, in an illumination plan that constitutes an optical ceiling that occupies a large area of the ceiling, a glass cover or an acrylic resin cover is used as an illumination cover that covers the lower surface of an illumination facility in which a large number of fluorescent lamps are arranged. Since the glass cover is heavy, not only is it difficult to remove and attach the cover accompanying the replacement of the fluorescent tube, but also the equipment load increases, so that the members constituting the ceiling structure become large. Moreover, although a high-class feeling is obtained, since various processing means are limited, various cover shapes cannot be obtained. On the other hand, acrylic resin covers are widely used as illumination covers of various designs because they are inexpensive, lightweight, highly workable, and have good transparency. However, since the acrylic resin itself is a flammable material, use restrictions may be imposed depending on the interior.

  In addition to these conventional lighting covers for optical ceilings, non-combustible film materials with good light transmission have been increasingly adopted as shades (covers) for optical ceilings. (See Non-Patent Document 1 and Non-Patent Document 2). The film material is lightweight and can be processed into various shapes. Because of its high expandability, it is possible to construct light film ceilings of various designs, so the genre as a light film ceiling is being established. . In particular, Non-Patent Document 2 is a homepage established by the applicant and discloses the characteristics of the optical film ceiling that the applicant has already provided as a product.

  By the way, the optical film ceiling shown in Non-Patent Documents 1 and 2 is shaped steel processing in which a lighting fixture such as a fluorescent lamp is attached in a recess provided at a predetermined location on the ceiling surface, and is attached along the periphery of the recess. The edge holding material attached along the edge of the peripheral edge of the ceiling membrane material is fixedly supported on a part of a support frame such as a turning edge formed by assembling the materials. For this reason, there is a gap between the periphery of the ceiling membrane material and the building side, and the support frame protrudes into the recess. May be reflected.

  In addition, since it is necessary to attach a support frame to the periphery, in a relatively narrow ceiling-embedded fluorescent lamp, the support frame cannot be directly attached to the reflector, so the membrane material cannot be attached as a shade. . Therefore, the object of the present invention is to eliminate the above-mentioned problems of the prior art, and to attach the end member of the film material constituting the light film ceiling directly to the reflector of the fluorescent lamp or the building frame. An optical film ceiling mounting structure is provided.

To do.

  In the above-mentioned invention, it is preferable that the support metal is a leaf spring member that is shaped to hold the film end holding member by pressing and urging the membrane end holding member at a part of the curved portion.

  Further, the membrane end holding member is attached to the end side of the membrane material by sandwiching the end side of the membrane material between the main body member which is a long member and the membrane pressing member. Is preferred.

  According to the present invention, since the end member of the film material of the light film ceiling can be detachably supported on a small and lightweight support metal, it is possible to construct a light film ceiling having a good appearance inexpensively and easily. This is advantageous in that maintenance work such as tube replacement of a fluorescent lamp can be easily performed.

FIG. Each drawing in FIG. 2 is a schematic look-up view of the ceiling surface to which the fluorescent lamp shown in FIG. The fluorescent lamp described above is covered from below by a film material 2 stretched near the lower end of the side surface of the reflector, as shown in FIG. The ceiling is made up. In this figure, the longitudinal direction of the fluorescent tube is shown short for the sake of explanation, but as shown in the figure, the length that the film material 2 covers the illumination is appropriately determined depending on the cutting size of the film material 2 from the original fabric, etc. It goes without saying that it can be set.

  Hereinafter, the structure of the optical film ceiling mounting structure and the mounting procedure will be described with reference to FIGS. As shown in FIG. 3 in an enlarged manner, the reflector 11 of the fluorescent lamp 10 has a trapezoidal shape with its lower end slightly widened and opened, and a socket (not shown) for supporting each fluorescent tube 12 is attached to the upper surface. ing. And the support metal object 20 which consists of a leaf | plate spring material shape-processed so that a cross section may make predetermined | prescribed curved shape is being fixed to the side surface of the reflecting plate 11 at predetermined intervals in the longitudinal direction (refer FIG. 2). As shown in FIG. 3, a part of a film end holding member 30 described later is locked to a part of the support metal 20, and the film material 2 covers the fluorescent tube 12 from below with a predetermined tension applied. So that it is stretched.

  As the film material 2, a known non-flammable film material having a light transmission property capable of obtaining a predetermined illumination efficiency and suitable as an interior material can be used. Specifically, it is a film material that has been subjected to non-combustible treatment, and uses a film material coated with a glass fiber fabric, such as tetrafluoroethylene resin, vinyl chloride resin, chloroprene rubber, chlorosulfonated polyethylene rubber, etc. Is preferred.

  As shown in FIG. 3, the support hardware 20 has a flat plate portion 21 that is in close contact with the reflecting plate 11, and continues to the flat plate portion 21. A plate in which the curved urging portion 22 that can be held by the root portion 23 and the locking portion 24 that presses and holds the membrane end holding member 30 against the reflecting plate 11 so as not to drop off are processed into an integrated corrugated shape. It is a spring member. In the present embodiment, a bent part made of spring steel is used for the support metal 20, and is spaced 0.3 to 0.5 m along the longitudinal direction in which the fluorescent tube 12 is arranged on the side surface of the reflector 11. It is riveted.

  As shown in FIGS. 3 and 4, the membrane end holding member 30 has a shape in which the main body member 31 and the membrane presser member 41 are joined together by a rivet 37 and are integrated with each other at the end side of the membrane material 2. It is a long member attached along the direction, and is set to a member length that can be attached to the supporting metal 20 of the stretched membrane. In the present embodiment, both the main body member 31 and the film pressing member 41 are made of aluminum. The upper end of the main body member 31 is provided with a fitting portion 32 with the upper end 41a of the membrane pressing member 41, and the intermediate portion 33 prevents the head of the rivet 37 from interfering when the membrane is attached as shown in FIG. The membrane material 2 is bent so as to be accommodated, so that the membrane material 2 can be securely clamped between the intermediate flange 34 and the distal end flange 44 of the membrane pressing member 41. Further, the shape of the extended portion 35 extending to the lower end and the thick portion 36 of the lower end makes it easy for the operator to handle the film end holding member 30, and the portion is fixed to the film material 2 by holding this portion. The film end holding member 30 can be easily attached to and detached from the support hardware 20.

  As shown in FIG. 3, the membrane pressing member 41 has a rounded head 42 fitted into the root portion 23 of the curved urging portion 22 of the support hardware 20, and an intermediate portion 43 is a locking portion of the support hardware 20. The membrane material 2 is firmly brought into close contact with the intermediate flange 34 of the main body member 31 by the tip flange 44.

  As shown in FIG. 4, the main body member 31 and the film pressing member 41 of the film end holding member 30 are formed of a film material by a rivet 37 attached from the main body member 31 side while sandwiching the end 2 a of the film material 2. 2 is integrally attached.

  FIG. 6 is an explanatory view showing a working state for holding the film material 2 having the film end holding member 30 attached to the end side 2a on the support metal 20 fixed to the inner surface of the reflecting plate 11. As shown in FIG. 5 (a), the head 42 of the membrane end holding member 30 is pressed against the lower end of the support hardware 20, and the U-shaped curved urging portion 22 at the intermediate position is pushed and widened. As indicated by the arrow in (b), when the main body member 31 is pushed up along the reflector 11 and the head 42 is pushed into the root portion 23 of the curved urging portion 22, the locking portion of the support hardware 20. 24 presses the intermediate portion 34 of the film end holding member 30 toward the reflecting plate 11, so that the film end holding member 30 is securely held by the support hardware 20 (see FIG. 1). At this time, the size of the membrane material and the tension of the membrane material (tension, tension shape) can be adjusted as appropriate depending on the attachment position of the membrane edge holding member 30, and the intermediate portion may be suspended, or sufficient tension may be applied. It is also possible to stretch it so that it is almost flat. When removing the membrane material 2, the membrane end holding member 30 is pulled down inward and slightly toward the inside by using the thick portion 36 at the lower end of the membrane end holding member 30 as a clue. The head 42 can be removed from the locking portion 24 of the support hardware 20.

  FIG. 6 shows an embodiment in which the optical film ceiling is constructed by using frame members 5 and 6 corresponding to the field material that is suspended from a ceiling slab (not shown) by a suspension bolt 4 and assembled in a lattice shape. . The members 5 and 6 constituting this frame body are formed of vertically-oriented aluminum rectangular tubes as shown in an enlarged cross section in FIG. 7, and as shown in FIG. The material 6 is combined with the material 6 so as to form a lattice shape partitioned vertically and horizontally, and is suspended on the ceiling slab by suspension bolts 4 attached to each lattice point and auxiliary suspension points. Then, as shown in FIG. 7A, the support metal 20 having substantially the same shape as FIG. It is fixed with. As a result, as shown in FIG. 6, the membrane material 2 equal to the internal area of the portion partitioned by each joint material 6 and the threading material 5 can be stretched between the joint materials 6. Also in this embodiment, the membrane edge holding member 30 is attached to the end 2a of the membrane material 2, and this membrane edge holding member 30 is attached to the side surface of the joint material as shown in FIG. The membrane material 2 can be easily stretched between the joint members 6 while being given a predetermined tension by being held by the fixed support hardware 20.

  FIG. 8 shows that the ceiling lighting in which the fluorescent lamps 10 as the ceiling lighting are arranged between the beams 8 and 8 arranged at a predetermined interval from the ceiling slab 7 is used as the optical film ceiling by the optical film ceiling mounting structure of the present invention. They are the side view which showed the Example, and a look-up figure. As shown in FIGS. 8 (a) and 9, the supporting hardware 20 is fixed to the side surface of the beam 8 at a predetermined interval by a fixing means (not shown) such as an anchor bolt, and the beams 8 and 8 facing each other. The membrane material 2 is passed between them, and the membrane end holding member 30 attached to the side edges 2a on both sides of the membrane material 2 is held by the support hardware 20, whereby the membrane material 2 having a predetermined width is stretched in the spanning direction. be able to. Similarly, the film material 2 is stretched in the adjacent section so that the space between the beams 8 and 8 is completely covered with the film material 2 and the entire ceiling surface through which the beam 8 passes at a predetermined interval is covered with the photo film ceiling. It can be.

  As described in the above embodiments, the film end holding member has a role of applying a uniform tension to the film material and holding it so that the film material does not wrinkle. For this reason, it is necessary to have a certain rigidity so as not to cause twisting and deflection. In this embodiment, an aluminum profile having a predetermined cross-sectional rigidity is used so as to satisfy this requirement. However, a synthetic resin molded product having a shape having the same cross-sectional performance can also be used. In this case, the weight of the member can be reduced. Moreover, when it is set as a resin product, it can also be colored in a desired color to achieve a design effect. Furthermore, the cross-sectional shape of each part of the main body member and the membrane pressing member constituting the membrane end holding member is easy to sandwich and hold the membrane material as described above, and the position is reliably held by the spring bias of the support hardware. However, as long as the shape can exhibit this effect, various modifications can be applied.

  In the above description, the light film ceiling mounting structure of the present invention has been described on the assumption that the light transmissive film material serves as a shade (cover) of the lighting equipment, but the ceiling surface that does not have the lighting equipment above. The present invention can also be applied when used as a membrane ceiling that constitutes.

  In addition, the membrane ceiling is not limited to the surface constituting the horizontal plane, but the membrane material is stretched on the inclined ceiling surface, and also on the slope that is classified as a wall, for example, the vertical surface, using the mounting structure described above. It goes without saying that it can be established.
