(First embodiment)
The roof fixing member according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3.

  FIG. 1 is a cross-sectional view showing a roof structure 100 using a roof material fixture 20 according to the first embodiment of the present invention. FIG. 2 is a cross-sectional view of the roof structure 100 taken along the line A-A ′ of FIG. 1. FIG. 3 is a partial enlarged cross-sectional view showing details of the incombustible film holding portion 22.

  The roof structure 100 of the present embodiment is configured to construct a roof by arranging a plurality of polycarbonate resin roof materials 10. As shown in FIG. 1, the roof material 10 has a hook 12 that extends downward (direction C in FIG. 1) at an end thereof, and is attached to a structure 60 (beam, horizontal member, etc.). The hook 12 is inserted into the roofing material fixture 20 and fixed. Further, the non-combustible film 14 is disposed below the roof material 10 by the roof material fixture 20 and separated from the roof material 10 by a predetermined distance H1. Due to the roof structure in which the non-combustible film 14 is disposed below the roof material 10, the roof structure 100 of the present embodiment has a predetermined fire prevention performance, and is particularly effective against flying fire.

  The structure of the roof material fixture 20 of this embodiment is demonstrated. As shown in FIG. 1, the roofing material fixture 20 includes a main body 21, a nonflammable film holding part 22 that holds the nonflammable film 14 in a plane, and a roofing material holding part 27 that holds an end of the roofing material 10. I have. The main body 21 of the roofing material fixture 20 includes a side surface 21a and a bottom surface 21b, and a cross section perpendicular to the major axis direction of the roofing material fixture 20 is substantially concave. In addition, as can be seen from FIG. 2, the roofing material fixture 20 is a long member manufactured according to the length of the roofing material 10, and is a structural portion 60 at the bottom of the roofing material fixture 20. Fixed to angle steel. Further, the end surface of the roofing material fixture 20 is closed by the pressing edge 50 and the end portion of the roofing material 10 is pressed from above by the pressing edge 50. The length of the roof material fixture 20 in the major axis direction is arbitrary, and is formed in accordance with the length of the roof material 10 to be attached.

  Further, as shown in FIG. 1, the roof material fixture 20 is a member for collectively fixing adjacent roof materials 10. Therefore, the roofing material fixture 20 has a line-symmetric shape with respect to the center line, and in the following, the nonflammable film holding part 22 and the roofing material holding part 27 described on the right side will be mainly described. The one described on the left side can also exhibit the same actions and effects.

  The incombustible film holding part 22 of this embodiment is demonstrated. The incombustible film holding portion 22 extends outward in the horizontal direction from the vicinity of the upper end portion of the side surface 21 a of the main body 21, and the incombustible film receiving portion 22 a formed integrally with the main body 21 and the incombustible film 14 are incombustible. The pressing piece 22b is pressed from above the film receiving portion 22a, and the screw 22c is used to fasten the non-combustible film receiving portion 22a and the pressing piece 22b. Further, screw holes for inserting screws 22c are formed in the non-combustible film receiving portion 22a and the pressing piece 22b.

  As shown in FIG. 3, the joining surfaces 22d and 22e where the incombustible film receiving portion 22a and the presser piece 22b are joined to the end of the incombustible film 14 are formed with minute irregularities and have a corrugated cross section. Therefore, the non-combustible film holding unit 22 can hold the end of the non-combustible film 14 firmly and planarly by friction between the joining surfaces 22d and 22e and the front and back surfaces of the end of the non-combustible film 14. Further, it is possible to prevent the non-combustible film 14 from being displaced when pulled.

  The distance between the roof member 10 and the incombustible film 14 is determined by the location where the incombustible film receiving part 22 a of the incombustible film holding part 22 is located on the side surface 21 a of the main body 21. In other words, in the present embodiment, the distance that the incombustible film receiving portion 22a is separated from the end of the side surface 21a of the main body 21 is the distance H1 provided between the roof material 10 and the incombustible film 14. The screw 22c employed in the non-combustible film holding portion 22 of the present embodiment is a countersunk screw, and when the non-combustible film 14 is held, the screw head does not protrude from the presser piece 22b. Therefore, the minimum distance between the roof material 10 and the incombustible film 14 is not limited by the protrusion of the screw head.

  A procedure for holding the end portion of the non-combustible film 14 in a plane by the non-combustible film holding unit 22 will be described below. First, the end portion of the non-combustible film 14 is disposed on the non-combustible film receiving portion 22a, and the pressing piece 22b is placed from above. After the incombustible film 14 is interposed between the incombustible film receiving portion 22a and the pressing piece 22b, a screw hole is formed so that the screw 22c is inserted into the incombustible film 14. Next, the screw 22c is inserted into the screw hole from above, and the non-combustible film receiving portion 22a and the pressing piece 22b are fastened by the screw 22c. The end of the non-combustible film 14 is sandwiched between the non-combustible film receiving portion 22a and the presser piece 22b, and the non-combustible film holding portion 22 holds the non-combustible film in a plane. In order to increase the holding power of the nonflammable film 14 of the nonflammable film holding portion 22, in addition to fastening with screws, an adhesive is applied to the bonding surfaces 22d and 22e of the nonflammable film receiving portion 22a and the pressing piece 22b and bonded. Also good.

  After the non-combustible film holding part 22 holds the non-combustible film 14 in a plane, a cushioning material 26 made of a rubber material or the like is disposed on the upper part of the presser piece 22b. By arranging the buffer material 26, the roof material 10 presses the presser piece 22 b through the buffer material 26 when the roof material 10 is held by the roof material holding portion 27. Thereby, holding | maintenance of the nonflammable film | membrane 14 is made stronger. The cushioning material 26 may be previously attached to the upper part of the pressing piece 22b with an adhesive.

  Next, the roof material holding part 27 of this embodiment will be described. The roof material holding portion 27 is provided on the upper portion of the main body 21, a contact portion 27 a that contacts the inner surface 12 a located inside the hook portion 12 of the roof material 10, and an end surface of the roof material 10, which is the end surface of the hook portion 12. It is comprised from the roof material receiving part 27b which receives the outer surface 12b located in the outer side. The roof material receiving portion 27 b extends vertically upward from the approximate center of the bottom surface 21 b of the main body 21. In addition, the contact portion 27a is provided in accordance with the shape of the inner surface 12a of the hook portion 12 from the side surface 21a toward the inside while being separated from the roof material receiving portion 27b by a predetermined distance. By inserting the hooking portion 12 between the abutting portion 27a and the roof material receiving portion 27b, the abutting portion 27a has the elasticity so that the inner surface 12a of the hooking portion 12 faces the roof material receiving portion 27b (FIG. 1). (D direction) is energized and the outer surface 12b of the hook portion 12 is received by the roof material receiving portion 27b, whereby the hook portion 12 is fixed and the roof material holding portion 27 holds the roof material 10.

  Moreover, the front-end | tip part of the hook part 12 is formed in the key shape, and if it inserts in the roof material holding part 27, it will prevent that the hook part 12 slips out.

  The roofing fixture 20 has a coupling portion 29 that protrudes outward in the horizontal direction in a flange shape from the lower end of the side surface 21a on the bottom surface 21b of the main body 21, and the roofing fixture 20 includes the coupling portion 29. It is connected to the structural part 60 of the building by screwing. Further, a screw hole 28 for attaching the pressing edge 50 is provided in the center of the bottom surface 21b of the roofing material fixture 20. By providing the screw hole 28, it is possible to attach the pressing edge 50 so as to block the end face of the roofing material fixture 20 as shown in FIG.

  The material of the roofing fixture 20 is not particularly limited, but is preferably made of metal from the viewpoint of durability and workability, and aluminum is particularly preferable. Moreover, the roofing fixture 20 is formed in the same cross section, and can be produced by arbitrary length by extrusion molding.

  The non-combustible film 14 of the present embodiment is a completely non-porous or substantially non-porous sheet-like member made of a non-combustible material, and the roof material 10 disposed above the non-combustible film 14 is fired as described above. It is for preventing it from being melted by the heat of the sparks and falling into the room. The incombustible film 14 of this embodiment employs a glass fiber sheet with a resin in which a silicone resin is thinly applied to a glass fiber sheet. A glass fiber sheet is a sheet having an opening ratio (percentage occupied by voids in stitches) of less than 5%, in which single fibers or twisted yarns of glass fibers are densely knitted with a structure such as plain weave, twill weave or satin weave. Since the glass fiber sheet itself has translucency, it is suitable as a daylighting roof structure. A glass fiber sheet with a resin coated with a silicone resin is preferably used because it is excellent in non-flammability, does not generate gas, and does not unravel the sheet. Moreover, the glass fiber sheet with a resin can be easily obtained as a long body, and can be used as a non-combustible film of a roof structure of any shape. In particular, since the incombustible film of the present embodiment is a glass fiber sheet having translucency, a roof structure having daylighting can be obtained by combining with a roof material made of polycarbonate resin having translucency.

  As a material other than the glass fiber sheet with resin, the non-combustible film 14 is a carbon fiber sheet, a resin-coated glass sheet or a carbon fiber sheet thinly coated with an acrylic resin, a fluorine resin, or the like, or a non-combustible paper having an opening ratio of less than 5%. Can be used. Further, the non-combustible film 14 may be a thin metal plate such as aluminum, stainless steel, or steel, or a metal mesh sheet having an aperture ratio of less than 5% obtained by densely knitting fine metal wires such as stainless steel and steel.

  In the present embodiment, a roof material made of polycarbonate resin is employed as the roof material 10. Polycarbonate resin has high mechanical strength and good light resistance, and is most preferably used as a roofing material. However, the roofing material 10 may be made of a material other than the polycarbonate resin, for example, an acrylic resin, a polyester resin, a polyvinyl chloride resin, or a reinforced resin containing glass fibers in these resins. These materials can have a total light transmittance of 20% to 95%.

  As shown in FIG. 1, the roof material 10 according to the present embodiment is a multilayer member including an upper surface material 10 a, a lower surface material 10 b, and ribs 10 c that connect them. Therefore, a large number of hollow portions 11 surrounded by the upper surface material 10a, the lower surface material 10b, and the ribs 10c are formed, and the roof material 10 is given rigidity and a heat insulating effect is exhibited by the hollow portion 11 to increase the size. This is particularly effective in the case of an area roof structure. When the roofing material 10 is made of polycarbonate resin, the thickness of the upper surface material 10a and the lower surface material 10b is 0.1 mm or more, preferably 0.1 to 1.0 mm, and the thickness of the rib 10c is The height of the rib 10c is 2 mm or more, preferably 2 to 50 mm, more preferably 10 to 40 mm, and the rib interval is 5 mm or more, preferably 0.1 mm or more, preferably 0.1 to 1.0 mm. By setting it as 5-50 mm, it can be set as the roofing material 10 which has rigidity, heat insulation, and intensity | strength.

  Moreover, the hook part 12 which protruded below (lower surface side, C direction) is provided in the both ends of the roofing material 10 as mentioned above. The hook portion 12 projecting downward is inserted into the roof material holding portion 27 at the top of the roof material fixture 20 from above. Then, the inner surface 12a of the hook portion 12 is brought into contact with the contact portion 27a of the roof material holding portion 27, and the contact portion 27a moves the hook portion 12 toward the receiving portion 27b of the roof material fixture 20 by its elastic force. By energizing, the roofing material 10 is held by the roofing material holding part 27. In this way, the roof material 10 can be fixed by the roof material fixture 20.

  The roof structure 100 and the roof material fixture 20 according to the first embodiment have been described above with reference to FIGS. In the roof structure 100 of the present embodiment, the nonflammable film 14 can be arranged from above by using the roof material fixture 20, and the hook portion 12 of the roof material 10 is inserted and held in the roof material holding portion 27. The roofing material 10 can be fixed only by it. Since it is not necessary to attach the non-combustible film 14 from below the roof and all members can be attached from above the roof, workability is improved.

(Second embodiment)

Compared to the roofing material fixture 20 of the first embodiment, the roofing material fixture 30 of this embodiment includes a support portion 41 that extends upward from the center of the bottom surface 31 b of the main body 31 as the roofing material holding portion 37. The difference is that the roof material 10 is held in cooperation with the roof material pressing portion 43. In addition, since the roofing material 10 and the nonflammable film 14 of this embodiment are the same members as the roofing material 10 and the nonflammable film 14 of 1st embodiment, the detailed description is abbreviate | omitted.

  Similar to the roof structure 100 of the first embodiment, the roof structure 110 of the present embodiment constructs a roof by arranging a plurality of roof materials 10. As shown in FIG. 4, the end 12 of the adjacent roofing material 10 is fixed by the roofing material fixing tool 30, and the non-combustible film 14 is arranged below the roofing material 10 by the roofing material fixing tool 30 at a predetermined interval H <b> 2. Has been.

  The structure of the roof material fixture 30 of this embodiment is demonstrated. As shown in FIG. 4, the roofing material fixture 30 includes a main body 31, a nonflammable film holding part 32 that holds the nonflammable film 14, and a roofing material holding part 37 that holds an end of the roofing material 10. . The main body 31 of the roofing material fixture 30 has a side surface 31a and a bottom surface 31b, and a cross section perpendicular to the major axis direction of the roofing material fixture 30 is substantially concave. The length of the roof material fixture 30 in the major axis direction is arbitrary, and is formed in accordance with the length of the roof material 10 to be attached.

  As shown in FIG. 4, the roofing material fixture 30 has a line-symmetric shape with respect to the center line. In the following, the nonflammable film holding part 32 and the roof material holding part 37 described on the right side will be mainly described, but those described on the left side can also exhibit the same operations and effects.

  The incombustible film holding part 32 of this embodiment is demonstrated. As shown in FIG. 4, the nonflammable film holder 32 of the second embodiment extends from the upper end of the side surface 31 a of the main body 31 to the outside in the horizontal direction and is integrally formed with the main body 21. It is comprised from the part 32a, the pressing piece 32b which presses the nonflammable film 14 from the upper direction of the nonflammable film receiving part 32a, and the screw | thread 32c which fastens the nonflammable film receiving part 32a and the pressing piece 32b. Further, a screw hole through which the screw 32c is inserted is formed in the non-combustible film receiving portion 32a and the pressing piece 32b. In addition, since the main body 21 and the nonflammable film receiving portion 32a are integrally formed, the cross section of the main body 21 and the nonflammable film receiving portion 32a has a reverse hat shape.

  The holding piece 32b has a locking portion 32f on one side, and the holding piece 32b has an L-shaped cross section. As shown in FIG. 4, the holding portion 32 b is locked to the inner surface of the side surface 31 a of the main body 31, so that the presser piece 32 b is not displaced in the outer direction of the main body 31. For this reason, the positions of the screw holes formed in the non-combustible film receiving portion 32a for inserting the screw 32c and the presser piece 32b are easily aligned, and the workability is improved.

  The joining surfaces 32d and 32e where the incombustible film receiving portion 32a and the presser piece 32b are joined to the end of the incombustible film 14 are formed with minute irregularities and have a corrugated cross section as in the first embodiment. Therefore, the nonflammable film holding portion 32 can firmly hold the end portion of the nonflammable film 14 due to friction between the joining surfaces 32d and 32e and the end surface and back surface of the nonflammable film 14. Further, it is possible to prevent the non-combustible film 14 from being displaced when pulled.

  The roof material holding part 37 of this embodiment will be described. The roof material holding portion 37 includes a plate-like roof material pressing portion 43 disposed on the upper surface of the end portion of the roof material 10 and a support portion 41 that supports the roof material pressing portion 43 from the main body 31. Since the support part 41 has connected the roof material pressing part 43 and the main body 31, the roof material pressing part 43 can press the edge part of the roof material 10 toward the downward direction. Therefore, the roof material holding portion 37 can hold the roof material 10 by sandwiching the end portion of the roof material 10 between the roof material pressing portion 43 and the main body 31.

  The support portion 41 of the present embodiment is realized by a bolt, and as shown in FIG. 4, the bolt head portion 41a is directed downward, and the bolt body 41b formed with a screw thread is disposed upward. The length L of the support portion 41 is longer than the height H3 when the roof material 10 is arranged on the roof material fixture 30, so that at least the end of the bolt body 41b protrudes from the upper surface material 10a of the roof material 10. It has become.

  In the center of the inner surface of the bottom surface 31b of the main body 31, a bolt fixing portion 39 for fixing the bolt head portion 41a is provided. The bolt fixing portion 39 is formed in accordance with the cross-sectional shape of the bolt head portion 41a of the support portion 41. Since the bolt main body 41b is inserted into the upper portion of the bolt fixing portion 39, the bolt fixing portion 39 has substantially the same width as the bolt main body 41b. A slit 39a is provided. The support part 41 inserts the bolt head 41a into the bolt fixing part 39 from the end of the roofing material fixture 30, and moves the bolt main body 41b to a predetermined position in a state where the bolt main body 41b exits from the slit 39a. By allowing the support portion 41 to move in the major axis direction, the support portion 41 can be adjusted to a position with a bolt hole 43a formed in the roof pressing portion 43 described later, and can be easily inserted. When the bolt head 41a is fixed to the main body 31 by welding, the support portion 41 cannot move, and if the positions of the bolt main body 41b and the bolt hole 43a are shifted, it is necessary to open a hole again, and the working efficiency is lowered.

  A roof material pressing portion 43, a nut 42 and a washer 45 for fixing the roof material pressing portion 43 are disposed at the upper end of the support portion 41 of the present embodiment. The roof material pressing portion 43 is a long plate having substantially the same length as the roof material 10 and the main body 31, and the bolt hole 43a for inserting the bolt main body 41b of the support portion 41 is at a predetermined position. Is formed. The number of bolt holes 43a is formed by the number of support portions 41 necessary to hold the roofing material 10. The roof material holding part 37 can hold the roof material 10 by tightening the nut 42 after the roof material 10 is interposed between the main body 31 and the roof material pressing part 43.
