[First embodiment]
BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out a ceiling joist according to the present invention and a ceiling structure using the same will be described in detail with reference to the accompanying drawings.

  First, a description will be given of the configuration of a ceiling joist according to the present embodiment and a ceiling structure using the ceiling joist. In the present embodiment, a joist ceiling material and a ceiling structure using the same will be described by taking as an example a case where a transport rail of a care transport lift is attached to a ceiling surface.

  FIG. 1 is a perspective view showing the best first embodiment for carrying out the ceiling-tied ceiling material according to the present invention, and FIG. 2 is the best view for carrying out the ceiling structure using the ceiling-tied ceiling material according to the present invention. FIG. 3 is a sectional view showing the best first embodiment for carrying out the ceiling structure using the joist ceiling material according to the present invention.

  The direction shown in the description of the present embodiment is based on joists, the direction in which the joists spanned between the beam members extend is the “longitudinal direction”, and the thickness direction of the joists (the direction perpendicular to the longitudinal direction) is The “width direction” and the height direction of the joists are referred to as “height direction” (see FIGS. 1 and 2).

  As shown in FIG. 1 and FIG. 2, the ceiling joist 1 according to the present invention is a member for forming a ceiling, and is a structural member 10 (see FIG. 2) such as a beam member 11 (see FIG. 2) facing each other. 2), the joist 20 spanned between and the ceiling member 30 constituting the ceiling surface are integrally formed.

  The joist 20 and the ceiling member 30 are constituted by an extruded shape member 21 integrally formed of aluminum or an aluminum alloy. As shown in FIG. 1, the joist 20 is formed in a vertically long rectangular shape that is long in the height direction, and has a hollow portion 22. A horizontal rib 23 is formed inside the hollow portion 22 of the joist 20. In the present embodiment, one horizontal rib 23 is formed (one step) in the hollow portion 22, and is positioned at an intermediate portion in the height direction of the joist 20. The horizontal rib 23 is formed so as to connect the side plates 24, 24 on both sides in the width direction of the joists 20. In the present embodiment, the horizontal rib 23 is provided only in one step in the middle portion of the joist 20 in the height direction, but the present invention is not limited to this. For example, when the joist 20 is high, two or more horizontal ribs 23 may be provided (see FIG. 5).

  The ceiling member 30 is configured by a plate-like member 31 that spreads in the width direction from the bottom surface or side surface of the joist 20. In the present embodiment, the plate-like member 31 is configured to spread from the bottom surface of the joist 20 to both sides in the width direction of the joist 20. The pair of plate-like members 31, 31 is formed so as to be perpendicular to the side plate 24 of the joist 20 and spread in both horizontal directions and extend in a strip shape along the longitudinal direction of the joist 20. It is comprised so that the same plane may be formed with 25 bottom plates 25a. Of the pair of plate-like members 31, an engaging stepped portion that engages with the tip of the plate-like member 31 of the ceiling member 30 of another adjacent joisted ceiling member 1 is located at the tip of one plate-like member 31. 32 is provided. The engagement step portion 32 is bent so as to be offset upward in the thickness dimension of the plate-like member 31, and a step having a dimension equivalent to the thickness dimension of the plate-like member 31 is formed. With such a configuration, when the tip flat plate portion 35 of the plate-like member 31 adjacent to the engaging stepped portion 32 is engaged, the tip flat plate portion 35 overlaps with the engaging stepped portion 32 and the surface of the ceiling is surfaced. It is supposed to be one.

  As shown in FIG. 2, the ceiling structure 5 according to the present invention is configured by arranging a plurality of joisted ceiling members 1 having the above-mentioned configuration in parallel along the width direction of the joists 20. The joist ceiling material 1 extends horizontally in a direction orthogonal to the extending direction of the beam material 11, and is spanned and fixed between the adjacent beam materials 11 and 11.

  In the present embodiment, as shown in FIG. 3, the beam member 11 is constituted by a square steel pipe 12. The beam member 11 is not limited to the square steel pipe 12, and may be a steel beam, a wooden beam, a reinforced concrete beam, or the like having another shape. The ceiling joist 1 is fixed to the beam 11 through an angle member 13 having an L-shaped cross section. The angle member 13 is made of an extruded shape member or angle steel made of aluminum or an aluminum alloy (in the present embodiment, an extruded shape member made of aluminum or an aluminum alloy). The angle member 13 is provided along the extending direction of the square steel pipe 12, and is arranged so that one side (vertical portion 13 a) abuts along the side surface 12 a of the square steel pipe 12. The angle member 13 is fixed to the square steel pipe 12 via bolts 14 and nuts 15. The bolt 14 is inserted from the side surface 12 b opposite to the side surface 12 a to which the angle member 13 is attached, and the tip portion 14 a passes through a bolt hole (not shown) formed in the angle member 13. Then, the angle member 13 is fixed to the beam member 11 by screwing the nut 15 into the tip portion 14 a of the bolt 14. A plurality of bolts 14 and nuts 15 are provided at predetermined intervals in the longitudinal direction of the angle member 13. A concave portion 16 for accommodating the head portion 14b of the bolt 14 is formed on the side surface 12b of the square steel pipe 12, and the head portion 14b of the bolt 14 is configured not to protrude from the side surface 12b of the square steel tube 12. . Thereby, it is possible to prevent the bolt 14 from interfering with the outer wall or the like.

  Both ends 1a (only one end is shown in FIG. 3) of the ceiling joist 1 are placed on the horizontal portions 13b of the angle members 13 facing each other. The end 1a of the ceiling joist 1 is fixed to the horizontal portion 13b of the angle member 13 by a known fixing means such as welding or a screw (not shown).

  As shown in FIG. 1, the joist ceiling material 1 is arranged so that the ends (engagement stepped portion 32 and tip flat plate portion 35) of adjacent plate-like members 31 face each other without a gap. By engaging the other engaging stepped portion 32 with the tip flat plate portion 35 of one plate-like member 31, the vertical displacement of the plate-like member 31 is prevented. In the present embodiment, the end portions of the plate-like member 31 are abutted without a gap, but may be arranged with a predetermined interval in the width direction of the joists 20. In this case, since the plate material of the engaging stepped portion 32 serves as a joint plate, the upper portion of the ceiling member 30 is not seen from the room. Moreover, since a plurality of joints are arranged in parallel and formed in a stripe shape, it is possible to provide a high-design ceiling that gives a light impression to the viewer.

  As shown in FIG. 2, a plurality of floor joists 41 are arranged at the upper part of the joist ceiling material 1 so as to be orthogonal to the longitudinal direction of the joists 20. A floor material 44 is provided above the floor joist 41 via a floor base material 43. If a floor joist 41 having a vibration damping function such as rubber is used, the vibration of the upper floor can be absorbed and the propagation to the lower floor can be prevented, so that a soundproof effect can be obtained. When the joist 20 is high, the floor base material may be provided directly on the joist 20 of the joist ceiling material 1 without providing the floor joist. Even in such a case, the joist 20 has high rigidity, and therefore it is difficult to transmit vibrations of the upper floor, so that the soundproofing effect can be obtained with the joist ceiling material 1 itself.

  As shown in FIG. 3, a transport rail 51 of a care transport lift 50 is attached to the ceiling surface. The transport rail 51 is configured, for example, by forming a flange portion 51b extending in the horizontal direction at the upper end of a rail portion 51a having a substantially C-shaped cross section and opening downward. The conveyance rail 51 is made of an extruded shape made of aluminum or an aluminum alloy, and is arranged so as to extend in a direction orthogonal to the longitudinal direction of the joists 20. The transport rail 51 is fixed to the ceiling surface by inserting bolts (not shown) from below into the flange portion 51b and the ceiling member 30 and tightening nuts (not shown) above the ceiling member 30. . Note that a nut may be fixed in advance on the upper surface of the bolt hole (not shown) of the ceiling member 30 and the bolts may be rotated and tightened to fix the transport rail 51 to the ceiling surface. According to this, since the bolt can be screwed only by the work from the lower side of the ceiling surface, the bolt tightening work becomes easy. The mounting position of the bolt and nut is preferably the base end of the ceiling member 30, that is, the vicinity of the joist 20. This is because the moment force applied to the ceiling member 30 increases as the mounting position moves away from the joist 20, so that the closer to the joist 20, the smaller the deformation of the ceiling member 30 can be made. Even if a bolt and a nut are attached to the tip of the ceiling member 30, the joist 20 and the ceiling member 30 are integrally formed, so that necessary structural strength can be ensured.

  Although not shown in the drawings, as another fixing structure, the bottom plate of joists is formed thick, screw holes are formed in the bottom plate, and screws or bolts are screwed into the screw holes, so that the transport rail is ceiling-mounted. You may make it fix to a surface. According to this, since the conveyance rail can be fixed to the joist part, it is structurally advantageous, and since the screw or the bolt can be screwed by the work from the lower side of the ceiling surface, the fixing work becomes easy. .

  As shown in FIG. 3, the traveling portion 52 of the care transport lift 50 is inserted into the rail portion 51 a of the transport rail 51. The traveling unit 52 is provided with wheels 52 a, and the wheel 52 a rotates on the lip 51 c of the transport rail 51, so that the care transport lift 50 moves along the transport rail 51. Of course, the structure of the transport rail 51 is not limited to the above-described structure, and there are various shapes depending on the shape of the transport lift 50 for nursing care. Moreover, the attachment direction of the conveyance rail 51 in this Embodiment is an example, Comprising: It determines with the usability of the conveyance lift 50 for care. For example, the conveyance rail 51 may be attached along the longitudinal direction of the joists 20. In this case, if the transport rail 51 is attached to the lower part of the joist 20 or the ceiling member 30 in the vicinity of the joist 20, it is structurally advantageous.

  Next, the operation of the ceiling joist member 1 and the ceiling structure 5 will be described while describing the construction procedure of the ceiling structure 5 using the joist ceiling member 1 having the above-described configuration.

  As shown in FIG. 2 and FIG. 3, first, an angle member 13 is attached to side surfaces 12 a of a pair of beam members 11, which are structural members 10 on which the joist ceiling member 1 is bridged, via bolts 14 and nuts 15. To fix. Thereafter, the joist ceiling material 1 is placed on the horizontal portion 13b (only one side is shown in FIG. 3) of the angle members 13 facing each other. Then, the joist ceiling material 1 is fixed to the horizontal portion 13b of the angle member 13 by known fixing means such as welding or screws (not shown). The joist ceiling material 1 is engaged with the upper end flat plate portion 35 so as to cover the engaging stepped portion 32 of the adjacent ceiling member 30 and attached one by one. At this time, the engaging stepped portion 32 allows the ceiling members 30 to be easily butted together and the joist ceiling materials 1 can be positioned smoothly and reliably.

  When the attachment of the joist ceiling material 1 is completed, the ceiling is completed. Here, since the joist ceiling material 1 is configured by integrally forming the joist 20 and the ceiling member 30, the joist 20 is installed by linking the joist 20 between the beam members 11. The ceiling is formed. Therefore, a new ceiling can be easily formed in the existing building, for example, in the atrium, if the structural material 10 such as the beam material 11 is provided. Further, since the ceiling joist 1 is made of an extruded shape made of aluminum or aluminum alloy, the ceiling member 30 can be used as it is as a surface finishing material by taking advantage of the texture of aluminum or aluminum alloy. Therefore, it is possible to omit the work of providing a suspension material from the joist and attaching the finishing material after attaching the ceiling base to the lower portion, as in the prior art, and the construction labor and time can be greatly reduced. In addition, since the angle member 13 is also made of an extruded shape member made of aluminum or aluminum alloy, the texture of the ceiling member 30 is the same as that of the ceiling member 30, and a uniform feeling of the ceiling surface can be obtained. Since the ceiling surface is formed to be flush and smooth, it is possible to separately attach a ceiling finishing material to the top surface.

  Next, as shown in FIG. 3, the conveyance rail 51 is attached to a ceiling surface. The transport rail 51 is attached to the ceiling member 30 of the joist ceiling material 1 using bolts and nuts. At this time, since the joist 20 and the ceiling member 30 are integrally formed in the joist ceiling material 1, the ceiling member 30 can be removed from the joist 20 even if the care lift 50 is suspended from the transport rail 51. There is no separation. The joist 20 is a member having high joint strength, such as the angle member 13, the bolt 14, and the nut 15, and is spanned over the beam member 11 (structure member 10). The load (not shown) can be reliably transmitted to the structural member 10. Therefore, the joist ceiling material 1 has strength and rigidity capable of suspending and supporting various facilities such as a care transport lift.

  Further, since the ceiling member 30 and the joist 20 are integrated, loads of various facilities such as the care transport lift 50 are smoothly transmitted from the ceiling member 30 to the joist 20, so the installation position of the transport rail 51 Alternatively, the mounting positions of the bolts and nuts are not limited to the installation positions of the joists 20, and the degree of freedom in designing the layout of the care transport lift 50 is improved.

  Furthermore, since the ceiling member 1 with a joist is provided with a ceiling member 30 made of a plate-like member 31 for each joist 20, it becomes a relatively small and lightweight member that is unitized, and is easy to construct and transport. It becomes.

  Moreover, since the joist 20 is comprised by the extruded shape material 21 which has the hollow part 22, while being able to achieve weight reduction of the joist ceiling material 1, the joist ceiling material 1 maintains high intensity | strength and rigidity. Can do. Further, since the extruded shape member 21 is used, the product accuracy is improved, and no gap or gap is generated in the joint portion (the butt portion between the ceiling members 30) with the adjacent joist ceiling material 1. Further, since the horizontal ribs 23 are provided inside the hollow portion 22 of the joists 20, the strength and rigidity of the joists 20 can be increased efficiently. Further, in order to improve the bending strength of the joists 20, even if the joists 20 are made high, the side plates 24 and 24 of the joists 20 are connected by the horizontal ribs 23. Can be prevented from being deformed.

[Second Embodiment]
FIG. 4 is a cross-sectional view showing the second best mode for carrying out the ceiling structure using the joist ceiling material according to the present invention.

  This embodiment is different from the first embodiment in the mounting structure of the joist ceiling material 1 and the beam material 11 (structure material 10). As shown in FIG. 4, the ceiling material 1 with a joist has a portion below the horizontal rib 23 cut out at both ends of the joist 20. The notch 26 is formed so that the upper end thereof is flush with the lower surface of the horizontal rib 23. The notch 26 is notched in the longitudinal direction of the joist 20 with a dimension approximately the same as the protruding length of the horizontal portion 13 b of the angle member 13. The end portion of the ceiling member 30 is also cut out in the same manner as the cutout portion 26 of the joist 20. The joist ceiling material 1 is manufactured by forming the notched portions 26 at both ends after forming the extruded shape member 21 having the same shape as the first embodiment.

  The joist ceiling material 1 is fixed by placing the lower surface of the horizontal rib 23 exposed from the notch 26 on the horizontal portion 13 b of the angle member 13. The horizontal ribs 23 are fixed to the horizontal portion 13b of the angle member 13 by known fixing means such as welding or screws (not shown). Since other configurations are the same as those in the first embodiment, the same reference numerals are given and description thereof is omitted.

  As described above, if the ceiling-mounted ceiling material 1 is joined to the structural material 10 via the horizontal ribs 23, a plurality of installation heights can be selected for the structural material 10 whose position is determined. The above structure is particularly effective when a ceiling surface is desired to be provided below the lower end surface of the beam member 11.

[Third embodiment]
FIG. 5 is a cross-sectional view showing the third best mode for carrying out the joist ceiling material according to the present invention.

  Such an embodiment is different from the first embodiment in the structure of the ceiling member 30 of the joist ceiling material 1. As shown in FIG. 5, the joist ceiling material 1 is formed in a cylindrical shape in which the ceiling member 30 has a hollow portion 33. Also in the present embodiment, the ceiling member 30 is constituted by the extruded shape member 21 formed integrally with the joist 20. The hollow portion 33 is formed in a rectangular shape that is long in the width direction of the joist 20. An engagement flat plate portion 34a that is flush with the ceiling surface is formed at one end portion of the ceiling member 30, and the engagement plate formed at the other end portion is offset upward by the thickness of the engagement flat plate portion 34a. A joint step 34b is formed. The engaging stepped portion 34b is configured such that the ceiling surface is flush with the engaging flat plate portion 34a of the adjacent ceiling member 30.

  The joist 20 is higher than the joist ceiling material 1 of the first embodiment, and the bending strength of the joist 20 is improved. In this case, the horizontal ribs 23 are provided in two stages to prevent the side plate 24 from being deformed.

  As described above, by forming the ceiling member 30 in a cylindrical shape having the hollow portion 33, the ceiling member 30 is lightweight and can retain high strength and rigidity. Strength and rigidity can be greatly increased. In addition, according to this configuration, the strength and rigidity of the ceiling member 30 are significantly increased. Therefore, even if a heavy transport rail for a nursing care lift is attached to the tip of the ceiling member 30, the ceiling member 30 is applied. Since the resistance force to the moment force is large, the ceiling member 30 is not deformed.

[Fourth embodiment]

By the way, in this Embodiment, the guide rail 55 of the movable partition 54 is formed in the lower part of the joist 20. The guide rail 55 is formed to extend in the longitudinal direction of the joists 20 (extrusion direction of the joist ceiling material 1), and is integrally formed with the joists 20 and the ceiling member 30. The guide rail 55 has a substantially C-shaped cross section and is configured to open downward. Here, the upper surface plate 55d of the guide rail 55 is a common member with the bottom surface plate 25a of the joist 20 (see a partially enlarged view of FIG. 6). The guide rail 55 is not limited to the movable partition 54, and can be used as, for example, a transport rail for the care transport lift 50 shown in FIG.

  In the guide rail 55, a gripping member 57 that grips the partition rail 56 that movably supports the movable partition 54 is provided. The grip member 57 is formed with a flange portion 57a that extends in the horizontal direction at the top. The flange portion 57a is inserted into the rail portion 55a of the guide rail 55 and is locked to the lip portion 55b at the lower end of the rail portion 55a. . A wheel 57 b is provided on the lower surface of the flange portion 57 a that is engaged with the lip portion 55 b, and the gripping member 57 is configured to be able to travel along the guide rail 55. A hollow portion is formed in the flange portion 57a. You may make it provide a reinforcement rib in this hollow part. In addition, it is good also as a structure which can slide the flange part 57a and the lip | rip part 55b, without providing the wheel 57b in the flange part 57a. A pair of gripping plates 57c that sandwich the partition rail 56 are formed at the lower portion of the flange portion 57a. The grip plate 57 c protrudes downward from the lower opening of the guide rail 55. The pair of gripping plates 57c are arranged in parallel to the extending direction of the guide rail 55 (longitudinal direction of the joists 20) with an interval equivalent to the width of the partition rail 56.

  The partition rail 56 is formed to have a substantially C-shaped cross section and open downward (see a partially enlarged view of FIG. 7 and FIG. 8). The partition rail 56 is disposed to extend horizontally in a direction orthogonal to the guide rail 55. The guide rail 55 is formed at a predetermined interval in the extending direction of the partition rail 56 (for example, about 900 mm (pitch when three joisting ceiling members 1 are provided between the guide rails 55), see FIG. 6). ing. The partition rail 56 is supported by a gripping member 57 provided in the guide rail 55 for each portion that intersects the guide rail 55. The partition rail 56 is fixed to the bottom surface of the holding member 57 or the flange portion 57a with screws (not shown) or the like.
