  Next, the attachment structure and method of the base material 32 with respect to the reinforcing material 30 in the ceiling structure 10 according to the present embodiment will be specifically described.

  FIG. 4 is a cross-sectional view showing an example of the mounting structure of the base material 32 to the reinforcing material 30, and is an enlarged view of the periphery of the predetermined base material 32 in FIG. FIG. 5 is a cross-sectional view showing a procedure for attaching the base material 32 to the reinforcing material 30 shown in FIG.

  The temporary fixing metal fitting 38 for temporarily fixing the base material 32 is fixed to the lower surface of the reinforcing material 30 using screws 48 as shown in FIG. The temporary fixing metal fitting 38 had an L shape bent and suspended from the contact surface with the reinforcing member 30, and an L shape protruding in the horizontal direction from the tip of the L shape and bent upward. Shape. That is, the temporary fixing metal fitting 38 has a configuration in which an engaged portion 38a facing upward with an L-shaped cross section is provided at the lower end of a plate member having an L-shaped cross section.

  In the base material 32, an engaging portion 32b is bulged and formed on the upper side surface of the base body 32a formed in a rectangular cross section, a mounting piece portion 32c is formed protruding on the other side surface of the base material, and a panel holding portion on the lower side surface. 42 is protrudingly formed. The engaging portion 32b has a claw portion 32d at the tip of the lower surface thereof, and is a portion that is engaged with the engaged portion 38a of the temporary fixing bracket 38 by a snap-in method. The attachment piece portion 32 c is a portion that is fastened and fixed to the reinforcing member 30 using the screw 40. The panel holding portion 42 is a portion that is formed in a substantially U-shaped cross section and in which the front edge portion or the rear edge portion of the ceiling panel 34 is inserted and held.

  When attaching the base material 32 to the reinforcing member 30, first, as shown in FIG. 5A, the engaging portion 32b is engaged with the engaged portion 38a of the temporary fixing bracket 38, and the claw portion 32d is hooked. . Then, as shown in FIG. 5B, the base material 32 is in a temporarily fixed state in which the base material 32 is engaged and held with the reinforcing material 30. Therefore, as shown in FIG. 5B, the attachment piece 32 c is fastened and fixed to the lower surface of the reinforcing member 30 by the screw 40. Thereby, the base material 32 is attached to the reinforcing material 30 in a state where the engaging portion 32b on one side is engaged with the temporary fixing metal fitting 38 and the mounting piece 32c on the other side is fastened and fixed to the reinforcing material 30. It is fixed (see FIG. 4).

  By the way, when dew condensation occurs on the inner surface of the roof 20, the dew condensation water may drop from the gaps of the ceiling 14. For this reason, the ceiling structure 10 according to the present embodiment may include a drainage structure 50 that appropriately drains the condensed water generated on the roof 20.

  Then, next, the drainage structure 50 provided in the ceiling structure 10 is demonstrated.

  FIG. 6 is a cross-sectional view showing an example of the drainage structure 50, and is an enlarged view of the periphery of the upper end portion of the predetermined beam member 18 in FIG.

  As shown in FIG. 6, the ceiling panel 34 is disposed to face the side surface of the beam member 18 in a state where the front edge portion and the rear edge portion thereof are held by the panel holding portion 42 of the base material 32. For this reason, the dew condensation water W generated on the inner surface of the roofing material 22 is dropped from the lower surface of the roofing material 22 and the flow W1 flowing along the lower surface of the roofing material 22 along, for example, the downward slope of the roof 20. A flow W2 flowing along the upper surface of the panel 34 is generated.

  Therefore, the drainage structure 50 of the present embodiment has a water receiving member 52 for receiving the condensed water W of the flow W1. The water receiving member 52 is an extruded profile having a substantially L-shaped cross section that opens toward the edge at a position below the edge of the ceiling panel 34 on the side surface of the beam member 18. The water receiving member 52 extends along the longitudinal direction of the beam member 18 and is fixed to the side surface of the beam member 18 with screws. Thereby, the water receiving member 52 collects the dew condensation water W of the flow W1 dripped on the front and rear side surfaces of the beam member 18 from the lower surface of the roof material 22, for example, and collects the collected water, for example, the outer surface of the left and right columns 16 Drain to the side. At this time, the water receiving member 52 is attached by sandwiching a water stop material 53 at a screwed portion with respect to the beam member 18. For this reason, the water collected by the water receiving member 52 is prevented from dripping from the gap between the beam member 18.

  Furthermore, the drainage structure 50 has a water receiving part 54 for receiving the condensed water W of the flow W2. The water receiving portion 54 is provided in the panel holding portion 42 that holds at least the front edge portion on the lower side among the panel holding portions 42 that hold the front and rear edge portions of the ceiling panel 34, thereby the longitudinal direction of the base material 32. Extends along. The lower plate of the water receiving portion 54 that supports the lower surface of the ceiling panel 34 is provided with a water stop convex portion 54a that protrudes upward at the opening edge thereof, and can receive water on the inner surface thereof. Thereby, the water receiving part 54 collects the dew condensation water W of the flow W2 which propagates the upper surface of the ceiling panel 34, for example, and drains the collected water, for example to the outer surface side of the right-and-left one support | pillar 16.

  By the way, as shown in FIGS. 2 and 3, the reinforcing member 30 is a long member along the front-rear direction of the roof 20. Therefore, if the ceiling 14 is installed by retrofitting the existing building 12 in which only the roof 20 is installed on the beam member 18 without the ceiling 14 provided, and the ceiling 14 is installed, the reinforcement 30 Installation work on the upper surface of the beam member 18 is difficult. That is, in the configuration shown in FIG. 2, when the reinforcing member 30 is inserted between the existing roof 20 and the beam member 18 and inside the mountain shape of the roof member 22 that is a folded plate, for example, the edge frame 24 is removed. Etc. are required, which is very time-consuming. For this reason, the ceiling structure 10 according to the present embodiment may use the reinforcing material 60 having a configuration that facilitates retrofitting.

  Then, the structural example and construction procedure of the reinforcing material 60 which improve the workability at the time of retrofitting are demonstrated next.

  FIG. 7 is a side sectional view showing a state in which the reinforcing member 60 having a divided structure is installed under the existing roof 20, and FIG. 8 is an explanatory view showing a construction procedure of the reinforcing member 60 shown in FIG. is there. FIG. 9 is an explanatory view showing a procedure for connecting the reinforcing member 60 using the connecting fitting 62.

  As shown in FIG. 7, the reinforcing member 60 includes two base end reinforcing members 60 a and 60 b that are installed at a distance from each other, and an intermediate structural reinforcing member 60 c that connects the base end reinforcing members 60 a and 60 b. Is a divided structure.

  One base end reinforcing material (base end structural reinforcing material) 60 a is inserted and disposed below the mountain shape of the roof material 22 and placed on the upper surface of the rear beam member 18. It is fastened and fixed using the bracket 64. The other base end reinforcing material (base end structural reinforcing material) 60 b is inserted and arranged below the mountain shape of the roof material 22 and placed on the upper surface of the front beam member 18, and is L-shaped with respect to the beam member 18. It is fastened and fixed using a metal fitting 64. The intermediate structural reinforcing member 60c is fastened and fixed to both ends of the proximal reinforcing members 60a and 60b that protrude from the upper surface of the beam member 18 and face each other by using the connecting fittings 62, respectively. The base end reinforcing members 60a and 60b and the intermediate structural reinforcing member 60c are formed of a metal material such as aluminum or steel having a substantially rectangular cross section, and the engaging piece portions projecting outward at the lower end portions on both sides in the width direction. 65 is an extruded profile.

  The connecting fitting 62 is prepared in a state where the ends of the base end reinforcing members 60a and 60b that are arranged to face each other are connected in advance using screws 66, respectively. The connecting metal fitting 62 is a member having a substantially hat-shaped cross section and opening downward, with the longitudinal direction being shorter than the proximal end reinforcing members 60a and 60b. The connecting fitting 62 has a shape capable of accommodating the base end reinforcing members 60a and 60b and the intermediate structural reinforcing member 60c in the opening (see FIG. 9). As shown in FIG. 9, engaged portions 62 a that protrude outward are provided at the lower end portions on both sides in the width direction of the connection fitting 62. Each engaged portion 62a has a claw portion 62b protruding downward and inward at the tip thereof, and is a portion to which an engagement piece portion 65 such as an intermediate structural reinforcing member 60c is engaged by a snap-in method.

  When constructing the reinforcing member 60, first, the connecting metal fitting 62 is put on one end of each of the proximal reinforcing members 60a and 60b, and the base metal reinforcing members 60a and 60b and the connecting metal fitting 62 are fastened with screws 66. Fix (see FIG. 8A). The fastening work between the base end reinforcing members 60a and 60b and the connecting fitting 62 can be performed in the same manner as the fastening work between the intermediate structural reinforcing member 60c and the connecting fitting 62 shown in FIG. Thereby, it will be in the state by which the connection metal fitting 62 was attached to the edge part of each base end reinforcement 60a, 60b. The connecting metal fitting 62 is connected so that about half of the longitudinal dimension thereof is located at a position protruding from the end of each of the proximal reinforcing members 60a and 60b.

  Next, as shown in FIG. 8A, for example, one base end reinforcing member 60a is inserted into the mountain-shaped inner side of the roofing material 22 from the end opposite to the connection fitting 62 side, and one beam member is inserted. 18 and is fixed to the beam member 18 with screws using an L-shaped metal fitting 64. Then, as shown in FIG. 8A, the end of the base reinforcing member 60a on the side of the connecting bracket 62 protrudes forward from the upper surface of the beam member 18. Similarly, as shown in FIG. 8A, the other base end reinforcing member 60b is inserted into the mountain-shaped inner side of the roof material 22 from the end opposite to the connecting fitting 62 side, and the other beam member 18 is inserted. And is fixed to the beam member 18 with screws using an L-shaped metal fitting 64. Then, as shown in FIG. 8B, the end of the proximal end reinforcing member 60 b on the side of the connection fitting 62 protrudes backward from the upper surface of the beam member 18. As a result, the connecting fittings 62 and 62 attached to the front and rear proximal reinforcing members 60a and 60b are arranged to face each other with a predetermined interval (see FIG. 8B).

  Therefore, as shown in FIGS. 8B and 9A, the front and rear ends of the intermediate structural reinforcing member 60c are respectively inserted from below into the connecting brackets 62 and 62 of the front and rear proximal reinforcing members 60a and 60b. To do. Then, as shown in FIG. 9B, each engagement piece 65 is engaged with each engaged portion 62a, and each engagement piece 65 is hooked on the claw portion 62b. If it does so, it will be in the temporarily fixed state by which the intermediate structure reinforcement 60c was engaged with the front-and-rear connecting metal fittings 62 and held. Therefore, the engagement piece portion 65 of the intermediate structural reinforcing member 60 c and the engaged portion 62 a of the connection fitting 62 are fastened and fixed using screws 68. As a result, the intermediate structural reinforcing member 60 c is connected and fixed to the base end reinforcing members 60 a and 60 b and the connecting fitting 62. As a result, as shown in FIG. 7, the base end reinforcing members 60 a and 60 b and the intermediate structural reinforcing member 60 c are attached and fixed to the upper surface of the beam member 18 in a state of being formed as one reinforcing member 60.

  As described above, in the ceiling structure 10 according to the present embodiment, the base material 32 is attached to the reinforcing member 30 (60) attached to the beam member 18 serving as a structural material for supporting the roof material 22, and the base In the structure in which the ceiling panel 34 is held by the material 32, the reinforcing member 30 (60) is provided with a temporary fixing bracket 38 that can engage the base material 32, and the base material 32 is engaged with the temporary fixing bracket 38. In this state, it is fastened and fixed to the reinforcing member 30 (60) by using a screw 40 as a fastener.

  Therefore, when the base material 32 is attached to the reinforcing material 30 (60) and the ceiling 14 is constructed, the base material 32 is temporarily fixed by engaging with the temporary fixing bracket 38, and the screw 40 can be easily fixed in this state. The fastening work used can be performed. Thereby, it is not necessary to screw the base material 32 with the screw 40 while supporting the base material 32 by hand, and the workability of the ceiling 14 is improved. At this time, the base material 32 is engaged with the temporary fixing bracket 38 by a snap-in method. For this reason, temporary fixing of the base material 32 can be performed more easily and smoothly, and workability is further improved.

  In the ceiling structure 10, a roof material 22 made of a folded plate having a mountain shape extending in a direction orthogonal to the longitudinal direction of each beam member 18 arranged in parallel is used. Then, as the reinforcing member 60, a proximal reinforcing member 60a placed on the upper surface of one beam member 18, a proximal reinforcing member 60b placed on the upper surface of the other beam member 18, and a proximal reinforcing member 60a. , 60b and intermediate structural reinforcement members 60c fastened and fixed to each other by using connecting fittings 62 respectively.

  Therefore, even in the case where the ceiling 14 is retrofitted to the existing roof 20 that does not have the ceiling 14, the reinforcing material 60 has a split structure, so that the reinforcing material 60 is formed of a folded plate. It can be easily installed between 22 and the beam member 18, and the workability is further improved. Of course, the reinforcing member 60 having a divided structure can be used not only when retrofitting the ceiling 14 but also when constructing the ceiling 14 together with the roof 20. Even in this case, since the reinforcing material 60 that is long and has a certain amount of weight is divided, higher workability than that of the reinforcing material 30 formed in a single bar shape can be obtained.

  At this time, in the ceiling structure 10, the intermediate structural reinforcing member 60 c is engaged with the connection fitting 62 in a snap-in manner. For this reason, the intermediate structural reinforcing member 60c can be temporarily fixed by being engaged with the connecting fitting 62 (base end reinforcing members 60a and 60b), and the fastening operation using the screw 68 can be easily performed in this state. This eliminates the need for screwing with the screws 68 while supporting the intermediate structure reinforcing member 60c by hand, and improves the workability of the ceiling 14.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  In the said embodiment, although the structure provided with the beam member 18 and the reinforcing material 30 (60) was illustrated as a structural material which supports the roofing material 22, you may provide the ceiling 14 with respect to structural materials other than these. . Further, for example, a structure in which the base material 32 is attached to the beam member 18 may be used.

  Further, for example, the structure of temporarily fixing the base material 32 to the temporarily fixing metal fitting 38 may be a structure other than the snap-in method described above. For example, a structure may be employed in which a bolt head is protruded from the temporary fixing bracket 38 side, and a hole formed in the base material is hooked and engaged with the head. Similarly, the structure of temporarily fixing the intermediate structural reinforcing member 60c to the connection fitting 62 may be another structure.
