Description

  The present invention relates to a ceiling structure of a room in a building.

  In general, in a ceiling structure of a room, a hanger is attached to the lower end of a suspension bolt that hangs down from a slab, and a plurality of field receivers are arranged in parallel by supporting the field receiver by the hanger. A plurality of ceiling panels are attached to the lower surface of the field edge by tapping screws that are screwed into the field edge to form a ceiling with multiple ceiling panels. Like to do.

  By the way, in the ceiling structure as described above, a plurality of field receivers supported by the suspension bolts and a plurality of field edge intersections arranged in an intersecting manner are connected to each other to form a grid-like ceiling foundation. The process of forming and the process of screwing a number of ceiling panels to the ceiling base with tapping screws is required, and a ceiling inspection opening is provided in the ceiling made up of a number of ceiling panels and an opening for attaching a lighting fixture is provided. Since it is necessary to provide the ceiling, it takes much time to form the ceiling, and the construction period is long and the cost is high.

  In addition, the weight is heavy, there is a problem in earthquake resistance, and there is also a problem that only a flat and fixed ceiling can be formed.

  An object of the present invention is to provide a ceiling structure that can be constructed in a very short period of time and can form a ceiling having a light weight, excellent earthquake resistance, low cost, and different shapes.

  In order to solve the above problems, in the present invention, a plurality of support bars are arranged substantially in parallel by supporting a support bar with suspension bolts that hang down from the slab, and each support bar has hook portions reaching both ends on both sides. And a flexible belt-like sheet having translucency in which hooks that can be engaged with the hook portion are attached to both side edge portions are spanned between adjacent support bars by engagement of the hook with the hook portion. Was adopted.

  Here, the support bar may be provided with a pair of hook portions on both sides thereof. In adopting such a support bar, it is possible to obtain a tension pattern in which two belt-like sheets are stretched at intervals between adjacent support bars, or arranged in steps on adjacent belt-like sheets. it can.

  In addition, a plurality of parallel rail members extending in the crossing direction with respect to the support bars are provided between the adjacent support bars, and a guide groove is provided at the lower part of each rail member, and can be slid along each guide groove. By supporting both ends of the belt-like sheet stretched between the support bars with a plurality of runners spaced apart from each other, it is possible to obtain a stretched pattern in which the belt-like sheet undulates in the length direction.

  According to the ceiling structure according to the present invention, the step of supporting the support bars with the suspension bolts and arranging the plurality of support bars substantially in parallel, and the hooks provided at both ends of the belt-like sheet on the hook portions of the adjacent support bars The ceiling can be formed by the step of engaging the belt and passing the belt-like sheet between the support bars, and since the belt-like sheet has translucency, the lighting fixture is formed between the ceiling and the slab formed by the belt-like sheet. Since the interior of the room can be illuminated by the lighting fixture, it is possible to eliminate the need for forming an opening for mounting the lighting fixture. Moreover, since the ceiling inspection opening can be formed by removing the belt-like sheet, it is not necessary to form the ceiling inspection opening.

  Therefore, the ceiling can be formed very easily in a short time, and a low-cost ceiling structure can be obtained. In addition, the use of the belt-like sheet makes it possible to obtain a ceiling structure that is lightweight and excellent in earthquake resistance.

  Furthermore, the belt-like sheet can obtain a bent tension state in which the central portion between both side edges hangs downward or a tension tension state in which tension is applied in the width direction by regulating the width dimension. Therefore, the ceiling excellent in the design from which a form differs can be formed by combining the extending pattern suitably.

  Here, by adopting a support bar in which a pair of hook portions are formed on both sides, two belt-like sheets can be provided vertically between adjacent support bars. In this case, since the light from the lighting device is softened by the two belt-like sheets, a calm room can be formed.

  Further, by adopting a support bar in which a pair of hook portions are formed on both sides, a step can be provided between adjacent strip sheets, and a three-dimensional ceiling can be formed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 4 show an embodiment of a ceiling structure according to the present invention. As shown in the drawing, a plurality of support bars 2 are provided below the slab 1, and each support bar 2 is supported by a plurality of suspension bolts 3 depending from the slab 1 and is arranged substantially in parallel.

  The support bar 2 is made of an extruded product of aluminum. The support bar 2 has a Y-shaped cross section with a bifurcated piece 5 provided at the lower end of the web 4. The upper end of the web 4 is opened at the upper surface, and a pair of flanges 6 are provided inwardly from the opening. Rail grooves 7 are provided. Further, a hook portion 8 that protrudes outward is provided at each lower end of the forked piece portion 5. The hook portion 8 may be upward as shown in FIG. 3, or may be horizontal as shown in FIG.

  When supporting the support bar 2 having the above-described configuration, here, the bent piece 11a provided at one end of the connector 10 is fixed by a pair of nuts 9 screwed into the lower part of the suspension bolt 3, and the rail of the support bar 2 is fixed. A bolt 12 having a head slidably inserted into the groove 7 is passed through a bent piece 11b provided at the other end of the connector 10, and a nut is attached to the end of the bolt 12 protruding on the bent piece 11b. 13 is screwed and tightened.

  A belt-like sheet 14 is stretched between the hook portions 8 of the support bars 2 adjacent to each other of the support bars 2 supported by the suspension bolts 3.

  The belt-like sheet 14 has translucency, flame retardancy, and flexibility. As such a belt-like sheet, a so-called Heim (trade name) manufactured by Toyobo Co., Ltd. can be adopted. Hooks 15 are attached to both side edges of the belt-like sheet 14. Here, the hook 15 may have a length extending over the entire side edge of the belt-like sheet 14 or may be a hook having a predetermined width. In the case of hooks having a predetermined width dimension, a plurality of hooks are attached to the side edges of the belt-like sheet 14 at intervals.

  Several types of belt-like sheets 14 having different colors and thicknesses are prepared, and an appropriate belt-like sheet 14 is selected and used according to the purpose of use of the room. These belt-like sheets 14 are stretched between adjacent support bars 2 by engagement of the hooks 15 with the hook portions 8 of the support bars 2, and a ceiling is formed by the tension of the belt-like sheets 14.

  As shown in FIG. 1, the belt-like sheet 14 may have a length obtained by dividing the support bar 2 into a plurality of parts in the length direction, or may have a length over the entire length of the support bar 2. Good.

  As shown in FIG. 2, the width of the belt-like sheet 14 is longer than the dimension between the opposing hook portions 8 of the adjacent support bars 2, and the central portion in the width direction hangs downward in the stretched state. 5 may be of a length set in the installed state, or, as shown in FIG. 5, is substantially equal to the dimension between the opposing hook portions 8 of the adjacent support bars 2, and in the width direction in the extended state. It may be in a tensioned state where tension is applied.

  In the ceiling structure shown in the embodiment, the support bar 2 is supported by the suspension bolt 3 and the plurality of support bars 2 are arranged substantially in parallel, and the belt-like sheet 14 is disposed on the hook portions 8 of the adjacent support bars 2 facing each other. The ceiling can be formed by engaging the hooks 15 provided on both side edges and passing the belt-like sheet 14 between the adjacent support bars 2.

  And since a ceiling inspection opening can be formed by removing the strip | belt-shaped sheet | seat 14, formation of a ceiling inspection opening can be made unnecessary. Moreover, as shown in FIG. 2, since the light from the lighting fixture A suspended and supported by the slab 1 can be projected indoors through the strip | belt-shaped sheet | seat 14, formation of the opening part for attachment of the lighting fixture A is formed. It can be unnecessary.

  Therefore, the ceiling can be formed very easily in a short period of time, and the cost is low. Moreover, the use of the belt-like sheet 14 makes it possible to obtain a lightweight and excellent earthquake-resistant ceiling structure.

  Further, by regulating the width dimension of the belt-like sheet 14, as shown in FIG. 2, the belt-like sheet 14 is bent in a bent state in which the central portion in the width direction hangs down, or as shown in FIG. Since it is possible to obtain a given tensioned tensioned state, and these tensioning patterns can be combined as shown in FIG. 6, several types of ceilings with different designs are formed. be able to.

  FIG. 7 shows another example of the support bar 2. This support bar 2 is different from the support bar 2 shown in FIG. 3 in that a pair of hook portions 8a and 8b are provided on the outer side surfaces of the bifurcated piece 5 respectively.

  By adopting the support bar 2 as described above, the belt-like sheet 14 can be passed between the upper hook portions 8a and the lower hook portions 8b of the adjacent support bars 2 facing each other. The atmosphere of the room can be changed greatly depending on how it is transferred.

  For example, as shown in FIG. 7, by placing the belt-like sheets 14 between the upper hook portions 8a and the lower hook portions 8b facing each other of the adjacent support bars 2, the two belt-like sheets 14 are arranged vertically. Since the light from the lighting device A shown in FIG. 2 is softened by the two belt-like sheets 14, a calm room can be formed.

  Further, as shown in FIG. 8, the belt-like sheet 14 is passed between the support bar 2 and the upper hook portion 8a of the support bar 2 provided on one side thereof, and provided on the support bar 2 and the other side. Since a step can be provided in the adjacent belt-like sheet 14 by passing the belt-like sheet 14 between the lower hook portions 8b of the support bar 2, a three-dimensional ceiling can be obtained.

  Although not shown in the figure, between two adjacent support bars 2, two belt-like sheets 14 are placed between one support bar 2, and one belt-like sheet 14 is placed between the other support bars 2. Since the light transmission amount at the portion where the two belt-like sheets 14 are passed is smaller than the light transmission amount at the portion where the one belt-like sheet 14 is passed, Can be formed.

  9 and 10 show another example of the ceiling structure according to the present invention. In this example, similarly to the case shown in FIG. 1, a plurality of support bars 2 are arranged substantially in parallel, and a plurality of rail members 20 extending in the crossing direction with respect to the support bar 2 are provided between adjacent support bars 2. Guide grooves 21 that are provided in parallel and that extend to both ends of each rail member 20 are formed in the lower portions on both sides of each rail member 20. The band-like sheet 14 stretched between them is supported at equal intervals on both side edges in the length direction, and the band-like sheet 14 is stretched in a wave-like manner in the length direction.

  Here, the rail member 20 is supported by a suspension bolt that hangs down from the slab 1.

  As described above, by providing the rail member 20 having the guide groove 21 between the plurality of support bars 2 arranged substantially in parallel, the belt-like sheet 14 spanned between the adjacent support bars 2 has a center in the width direction. Three tension patterns are obtained: a curved tensioned state in which the portion hangs downward, a tensioned tensioned state in which tension is applied in the width direction, and a wavy tensioned state in which waves strike in the length direction. It is possible to obtain a ceiling rich in change by appropriately combining these extending patterns.

  Further, by disengaging the hook 15 at one end of the belt-like sheet 14, the belt-like sheet 14 can be folded in a bellows shape, and the opening can be formed by the folding.

  In the example shown in FIG. 10, guide grooves 21 with open side surfaces are formed on both side surfaces of the rail member 20, but guide grooves 21 with open bottom surfaces are provided on both lower sides of the rail member 20 as shown in FIG. 11. Also good.
