And a fitting portion 26 that is formed by protruding upward from the end portion of the protrusion 25 and bent into a substantially inverted U-shaped cross section, and the inside (roofing material body 20) from the tip (outer lower end) of the fitting portion 26. The contact portion 27 is formed so as to protrude substantially horizontally toward the side) and has a substantially inverted U-shaped cross section. The protrusion 25 and the contact portion 27 are formed so as to face each other. . The other connecting portion 22 has a substantially arc shape that protrudes upward, and has an arc portion 28 that protrudes outward and obliquely upward from the side end portion of the roofing material body 20, and an upper portion from the tip of the arc portion 28. Projecting portion 29 formed so as to project substantially vertically, receiving portion 30 formed projecting substantially horizontally outward from the tip of projecting portion 29, and leading end of receiving portion 30 facing upward It is comprised from the to-be-fitted part 31 protruded in the substantially reverse V shape of the cross section.

  And when laying said roofing material 4 using the suspension A of FIG. 1, it carries out as follows. First, the heat insulating material 2 is placed on the roof base 1. Here, the heat insulating material 2 is formed in a block shape or a plate shape, and can be formed of, for example, a resin foam material such as polystyrene foam or polyurethane foam, or an inorganic fiber material such as glass wool or rock wool. . The roof base 1 is formed by using a roof frame member 32 such as a steel frame main house, a field plate 33 placed on the roof frame member 32, and a roofing material 34 laid on the field plate 33. The field board 33 can be formed of plywood or the like, and as the roofing material 34, asphalt roofing or the like can be used. In addition, the roofing material 34 can be used as needed and does not need to be laid. Next, the roof material 4 is laid on the heat insulating material 2 placed on the roof base 1. In this case, the roofing material 4 is arranged with the longitudinal direction of the connecting portions 21 and 22 substantially parallel to the inclination direction of the roof base 1 (for example, the eaves-ridge direction). Further, the side end surface 2a of the heat insulating material 2 and the outer surface 31a of the fitted portion 31 of the one connection portion 22 are arranged substantially vertically in a straight line.

Next, as shown in FIG. 3A, the roof material fixing suspension A of the present invention is attached to the roof material 4 placed on the roof base 1 and the suspension A is fixed to the roof base 1. The suspension A is attached to the roof material 4 by inserting the engaging portion 11 into the fitted portion 31 from above. A plurality of suspensions A can be provided on the fitted portion 31 along the longitudinal direction thereof. Further, as shown in FIG. 3 (b), the support piece 3 on one side (the one protruding to the opposite side of the fixed portion 6) of the suspension A attached to the fitted portion 31 is located below the received portion 30. It is located and the tip of this support part 3 will be in the state which adjoined to the undersurface of receiving part 30. Furthermore, the fixing portion 6 of the hanging piece A attached to the fitted portion 31 is directly fixed to the roof base 1 on the side of the side end face 2a of the heat insulating material 2. At this time, the fixing portion 6 is disposed on the roofing material 34 of the roof base 1 (or on the field plate 33 in the absence of the roofing material 34), and a fixing tool 35 such as a screw is placed on the field plate 33 from above the fixing unit 6. And it is made to drive in to the roof frame material 32. Further, the surface opposite to the fixing portion 6 of the locking portion 5 of the hanging element A is made to follow the side end surface 2 a of the heat insulating material 2. In this way, the roof material 4 can be fixed to the roof base 1 with the hanging element A. Incidentally, Oite the present invention, the "fixing portion 6 of the retaining clips A fixed directly to the roof bed 1", the heat insulator 2 having a thickness shrinks by aging between the roof bed 1 and the fixed part 6 It means that the fixing portion 6 is fixed to the roof base 1 without being interposed. Therefore, a case where a spacer or the like is interposed between the roof base 1 and the fixing part 6 for the purpose of non-landing adjustment, etc. is also included in “directly fixing the fixing part 6 to the roof base 1”.

  Thereafter, as shown in FIG. 3C, the heat insulating material 2 different from the heat insulating material 2 is placed on the roof base 1. The new heat insulating material 2 is placed on the fixed portion 6 of the above-described hanging member A whose side end portion is fixed to the roof base 1. Accordingly, the fixing portion 6 is disposed below the heat insulating material 2. Moreover, the side end surface 2a of the new heat insulating material 2 is made to lie along the surface on the fixed portion 6 side of the locking portion 5 of the hanging element A. Therefore, the hanging element A is in a state of being disposed between the adjacent heat insulating materials 2 and 2. Next, as shown in FIG.3 (d), the heat insulating material 2 newly mounted by the scattering prevention piece 7 of the suspension A is fastened and hold | maintained. In this case, the scattering prevention piece 7 is rotated downward with its base as a fulcrum, and the insertion piece 12 is inserted into the upper surface of the heat insulating material 2 and locked. Thereby, it can fix temporarily so that the heat insulating material 2 may not be scattered by a wind in the middle of construction.

Next, a new roof material 4 different from the above is placed on the newly placed heat insulating material 2. At this time, as shown in FIG. 3 (e), the connecting portion 22 provided with the fitted portion 31 of the existing roof material 4 and the connecting portion 21 provided with the fitted portion 31 of the new roof material 4. And connect. In this case, the fitting part 26 of the new roofing material 4 is fitted into the fitted part 31 of the existing roofing material 4 from above, and force is applied by pressing the fitting part 26 from the upper side by hand or by stepping with a foot. . In this way, by applying a force from above to the fitting portion 26 of the upper roof material 4, the fitting portion 26 of the upper roof material 4 moves downward while elastically expanding, and the upper roof material 4 When the projection 25 of the 4 reaches the concave step 14 of the rib 13 of the suspension A and the contact portion 27 of the roofing material 4 reaches the lower side of the end of the engagement portion 11 of the suspension A, it is fitted. The portion 26 is restored to its original shape from the state of being expanded by the restoring force (spring back), and the tip of the protrusion 25 of the upper roof material 4 enters the concave step portion 14 and comes into contact with the bottom surface of the roof material 4. The contact portion 27 is inserted between the tip of the engaging portion 11 and the receiving portion 30 of the lower roof material 4. In this way, under the fitting portion 26 of the roof material 4 newly arranged, the fitted portion 31 of the existing roof material 4 fixed on the roof base 1 and the suspension fitted thereto. By fitting the upper part of the child A, as shown in FIG. 4A, the adjacent roofing materials 4 and 4 can be connected to each other and the newly installed roofing material 4 is attached to the hanging element A. It is locked and fixed to. Further, the other support piece 3 (the one projecting toward the fixed portion 6) of the suspension A is located on the lower surface of the projection 25 of the newly disposed roof material 4, and the tip of the support piece 3 projects. The state is close to the lower surface of the portion 25. Then, by repeating the above series of operations, a plurality of roofing materials 4 can be laid on the roof base 1 to form a roof.

  In the construction structure of the roof material 4 according to the present invention, as shown in FIG. 4B, in order to directly fix the suspension A not to the upper surface of the heat insulating material 2 but to the upper surface of the roof base 1 below the heat insulating material 2. In addition, even if the heat insulating material 2 shrinks in the thickness direction due to a change over time and a gap s is generated between the roof material 4 and the heat insulating material 2, it is possible to prevent the attachment strength of the suspension A from being affected. Therefore, the attachment strength of the suspension A does not decrease due to the shrinkage of the heat insulating material, and the decrease in the attachment strength of the roof material 4 by the suspension A can also be prevented. Further, even when the heat insulating material 2 contracts due to a change over time, the connecting portions 21 and 22 of the roof material 4 can be supported by the support piece 3, and the fitting portion 26 and the fitted portion 31 are fitted. In addition, the connection between the connecting portions 21 and 22 and the suspension A can be prevented from being removed, and the attachment strength of the roofing material 4 can be ensured over a long period of time.

  FIG. 5 shows another embodiment of the roof material fixing hanger A of the present invention. This hanging element A is formed by providing a joint portion 8 and a spacer portion 9 in FIG. 1, and other configurations are the same as those in FIG. The joining portion 8 is a part of the engaging portion 11 by providing a slit 40 in the engaging portion 11 at a substantially central portion in the width direction of the locking portion 5 (between the support piece 3 and the scattering prevention piece 7). Is formed as the joint 8. The slit 40 reaches the tip of the engaging portion 11, whereby the joint portion 8 is formed to be bendable around the base portion.

  On the other hand, the spacer portion 9 is provided at both end portions of the fixed portion 6 and has a reverse V-shaped cross section. In addition, the spacer portion 9 is normally provided so as to protrude above the upper surface of the fixed portion 6, but can be bent and disposed below the fixed portion 6 as necessary. The spacer portion 9 is bent at its base portion, but it is preferable that a long slit is provided in a part of the base portion of the spacer portion 9 in a direction orthogonal to the width direction of the fixing portion 6 so that it can be bent by hand. Further, the fixing portion 6 is formed with a locking groove 6a having a substantially inverted V-shaped cross section that opens on the lower surface. The locking groove 6a is substantially parallel to the short side of the fixed portion 6, and can be provided one by one on both sides of the fixed portion 6, and can be formed by, for example, pressing.

  5 can fix the roofing material 4 to the roof base 1 by the same procedure as that of FIG. 1, but the roofing material 4 and the locking part 5 are connected by the joint 8. They are joined together. That is, after attaching the engaging part 11 to the fitted part 31 from the upper side and attaching it to the roof material 4, as shown in FIG. 6, the joining part 8 is bent so as to be in close contact with the surface of the fitted part 31. Thus, the fitted portion 31 is tightened and caulked at the joint portion 8. Thereby, in addition to latching, the roofing material 4 and the suspension A can be caulked and firmly joined. Conventionally, the roof material 4 is directly placed on the roof base 1, and the roof material 4 is less likely to move during construction due to friction with the roof base 1, but in the construction structure of the present invention, the roof material 4. Is placed on the upper surface of the heat insulating material 2, the friction between the roof material 4 and the roof base 1 is small, and the contact area between the roof material 4 and the roof base 1 may be reduced depending on the construction accuracy. Therefore, when the roof material 4 and the engaging portion 11 are simply locked, the roof material 4 placed on the heat insulating material 2 is fixed to the suspension A when the suspension A is fixed to the roof base 1. There is a case where the roof material 4 cannot be constructed at an accurate position due to a shift in the downward inclination direction (water flow direction). Therefore, the roof material 4 placed on the heat insulating material 2 is fixed when the suspension A is fixed to the roof base 1 by caulking the suspension A and the roof material 4 by the joint 8 as described above. It can be prevented from shifting in the downward inclination direction with respect to the suspension A, and the roof material 4 can be easily constructed at an accurate position.

  Moreover, when there is an unevenness | corrugation (non-landscape) on the upper surface of the roof base 1, there exists a possibility that the mounting strength of the roof material 4 may fall by the rattling A fixed to the roof base 1 generating. In this case, the spacer portion 9 is bent below the fixed portion 6 so that the state shown in FIG. 7A is changed to the state shown in FIG. The spacer part 9 is protruded to the side. In this case, one or both spacer portions 9 can be bent as necessary. Further, the tip of the spacer portion 9 is inserted and locked in the locking groove 6a, so that the spacer portion 9 having a substantially V-shaped cross section can be prevented from being crushed by a load. And when the fixing | fixed part 6 is mounted in the roof base | substrate 1, by positioning the spacer part 9 in a concave part, the level | step difference with a convex part can be absorbed in the spacer part 9, and the hanging element A is attached. It can be fixed almost horizontally without rattling. Although the protrusion dimension of the spacer part 9 from the lower surface of the fixing | fixed part 6 is not specifically limited, For example, it can be set to about 5 mm. Moreover, the case where the existing roof is repaired etc. can be illustrated as the roof base | substrate 1 with an unevenness | corrugation in an upper surface. In this case, the new roofing material 4 may be constructed so as to cover the existing roofing material (for example, the decorative slate plate) while leaving it. Therefore, the existing roofing material becomes the roof base, and the hanging element A must be fixed to the roofing material. However, since the existing roofing material is partially overlapped, the existing roofing material is adjacent to the existing roofing material. There is a step between them. Therefore, such a level difference can be absorbed by the spacer portion 9 and the suspension A can be fixed.

  8 (a) and 8 (b) show another embodiment of the roof material fixing suspension A of the present invention. 1 is formed by bending a metal plate such as an iron plate or a steel plate, as in the case of FIG. 1, and includes a flat plate-like fixed portion 6 and an end portion of the fixed portion 6. And a locking portion 5 formed so as to protrude substantially vertically upward. An engaging portion 11 having a substantially inverted U-shaped cross section that is bent back and bent to the opposite side of the fixing portion 6 is formed on the upper portion of the locking portion 5. Further, a support piece 3 that protrudes on the opposite side to the fixed portion 6 is provided in the locking portion 5. The support piece 3 can be formed by cutting and raising a part of the locking portion 5 substantially perpendicularly to the surface of the locking portion 5. Further, the support piece 3 is located at a substantially central portion in the width direction of the locking portion 5, above the central portion in the vertical direction of the locking portion 5 and below the tip of the engaging portion 11. In addition, a pair of rib portions 13 projecting toward the fixed portion 6 are formed at both end portions of the locking portion 5. The rib portion 13 is long in the vertical direction, and is long in the vertical direction from the upper portion of the locking portion 5 to the upper surface of the fixing portion 6. In addition, the joining portion 8 is formed as a joining portion 8 by providing a slit 40 in the engaging portion 11 at one side end of the locking portion 5. The slit 40 reaches the tip of the engaging portion 11, whereby the joint portion 8 is formed to be bendable around the base portion. Further, a scattering prevention piece 7 is formed on the upper surface of the fixed portion 6. The scattering prevention piece 7 can be formed so as to protrude substantially perpendicularly to the upper surface of the fixed portion 6 by attaching, for example, an L-shaped metal fitting to the upper surface of the fixed portion 6. The scattering prevention piece 7 may be provided at the side end portion of the locking portion 5 so as to protrude toward the fixed portion 6. Other configurations are the same as those in FIG.

It will be in the state which adjoined the lower surface of. Moreover, as shown in FIG. 6, the roof material 4 and the latching | locking part 5 are caulked and joined by the junction part 8 similarly to the above. Furthermore, the fixing portion 6 of the hanging piece A attached to the fitted portion 31 is directly fixed to the roof base 1 on the side of the side end face 2a of the heat insulating material 2. At this time, the fixing portion 6 is disposed on the roofing material 34 of the roof base 1 (or on the field plate 33 when the roofing material 34 is not provided), and a fixing tool 35 such as a screw is placed on the field plate 33 from above the fixing portion 6. And it is made to drive in to the roof frame material 32. Further, the surface opposite to the fixing portion 6 of the locking portion 5 of the hanging element A is made to follow the side end surface 2 a of the heat insulating material 2.
