Then, by fixing the groove lid 5 to the groove frame 43 of the rafter decorative material 4 in the fixed state, the groove cover 43 is closed, and the groove frame 43 is closed. 45 is prevented from being exposed.

  Accordingly, in the roof frame of this example, in order to perform repair or maintenance such as replacement of the damaged roof panel 3, for example, the rafter decorative material 4 is removed and the screws 21 are released from the rafter 1 from the substrate 11 side. The rafter cover 2 needs to be removed, and in this case, the removal of the rafter decorative material 4 requires the removal of the groove lid 5 and the release of the lateral screws 45 of the groove frame 43 as the preceding steps. Therefore, the groove lid 5 can be easily mounted, removed and reattached as necessary, and can be reproduced in a good fit similar to that at the beginning of the mounting. In addition, it is possible to eliminate plastic deformation caused by removal of maintenance and re-installation due to this.

  In other words, the groove lid 5 is formed through a lid substrate 61 and a groove cover body 6 made of an aluminum extruded material in which a support strip 62 is integrally formed on the back surface thereof, and a support strip 62 on the back surface of the groove lid body 6. Supporting the groove lid main body 6 with a plurality of short and intermittently arranged snap-in members 7 of a hard synthetic resin extruded material at a predetermined interval in the longitudinal direction of the back surface. The snap-in attachment of the groove lid 5 to the groove frame 43 of the material 4 is performed intermittently in the longitudinal direction of the groove frame 43 via the snap-in member 7 of the groove lid 5.

Supporting strip 62 of the Mizofuta body 6, which, while a support groove strip forming a T-shaped cross section by a pair of L-shaped projections standing upright on the back widthwise intermediate position of the cover substrate 61, the snap member 7, the the support slide board 71 slides fitted into the groove strip, the width direction outer side of the pair of L-shaped projections are bent towards the and the widthwise outer erected in the width direction intermediate position of the slide base plate 71 And a pair of bent ridges 72 forming one snap-in locking groove 74 between both ends in the width direction on the back surface of the lid substrate 61, and the one snap-in locking groove 74 is snap-in-mounted intermittently in the longitudinal direction of the groove frame 43 by snap-in locking to the other locking projection 44 of the snap-in locking arranged in the groove frame 43, In the snap-in member 7 The locking groove 74 above the bent protrusion 72 of the pair, located so as to induce snap locking of the locking grooves 74 and the engaging projection 44 is inclined inwardly projecting mutually perform a reliable locking In this example, a pair of inverted C-shaped inclined guides are provided so that the locking groove 74 is prevented from opening by deformation of the snap-in member 7 so that the snap-in mounting can be stably maintained. In this case, the snap-in member 7 is intermittently arranged with respect to the groove cover 5 except that both ends in the longitudinal direction of the groove cover 5 are set as non-positioning positions. As a thing.

At this time, the bent ridge 72 of the snap-in member 7 has a shape and dimensions such that a pair of L-shaped ridges on the lid substrate 61 are fitted, and a tapered inclined locking portion is formed on the L-shaped ridge. A pair of laterally oriented V-shaped grooves are formed on the lid substrate 61 so as to cover the side surfaces, in the vicinity thereof, and between the inclined surfaces and the back surfaces of both ends of the lid substrate 61 in the width direction. A pair of laterally V-shaped grooves is used as one locking groove 74 for snap-in engagement with the other snap-in locking strip 44 of the groove frame 43. That is, if this is shown in relation to the shape and dimensions of the bent ridge 72, the lid substrate 61 of the groove lid body 6 in the groove lid 5 of this example has the same length and width as the groove frame 43, For example, a long wall having a thickness of 2 mm, a pair of L-shaped protrusions arranged on the back surface, and the aluminum extruded material formed with the above-mentioned T-shaped support groove, that is, the support stripe 62, cut. On the other hand, the snap-in member 7 is L-shaped on the back surface of the slide substrate 71 fitted to the support strip 62, and its free end is folded back to the slide substrate side, and its tip is tapered and inclined. Bending ridges 72 each having a C-shaped cross section having a locking portion, and the inclined guide piece 73 protruding so as to extend the locking portion of the bending ridge 72 upward while maintaining its inclination, are formed. For example, ASA, AES, PC, POM, PA etc. The long bar material of the hard resin extruded material is cut, for example, 1 to 1.5 cm in width, 1.2 cm in this example, 5 to 6 mm in height, and 5 in this example. .8 mm, length is 3 to 10 cm, and in this example, it is a narrow bar shape formed to 5 or 6 cm.

  The snap-in member 7 is formed on the inner side of the groove lid body 6 except for a length of about 10 to 15 cm, for example, at both ends in the longitudinal direction of the groove lid body 6 so that both ends in the longitudinal direction of the groove lid 5 are not arranged. In the intermittent arrangement except for both ends in the longitudinal direction, the slide substrate 71 erected on the bent projection 72 in the snap-in member 7 is placed on the support strip 62 of the lid substrate 61 in the longitudinal end portion thereof. For example, it is performed by setting the pitch so that one snap-in member 7 is positioned at 40 to 60 cm of the lid substrate 61, 50 cm in this example, and 50 cm in this example.

  At this time, the snap-in member 7 is provided with a fixing measure of the snap-in member 7 with respect to the lid substrate 61 so as to fix the position on the lid substrate 61. This is performed by fixing means 75 such as bonding of the snap-in member 7 and caulking near the end of the snap-in member 7 with respect to the lid substrate 61. In this example, for example, the longitudinal direction of the intermittently arranged snap-in member 7 At both ends, the lid substrate 61 is subjected to spot-like caulking from its upper surface side and fixed so as to prevent the snap-in member 7 from moving.

  Therefore, when the length of the rafter 1 to rafter decorative material 4 is set to a reference dimension such as 1.8 m, 2.4 m, for example, the groove lid 5 formed slightly shorter than this is formed on the back surface of the lid substrate 61. The snap-in members 7 having a length of about 5 or 6 cm are intermittently arranged at a pitch of 50 cm, leaving the length of about 10 to 15 cm at both ends in the longitudinal direction, and the snap-in member is thus attached to the groove lid body 6 in this way. The groove lid 5 in which the groove 7 is intermittently arranged is engaged with one of the snap-in latches 44 corresponding to the other snap-in locking strip 44 of the groove lid 5 at both ends in the width direction at the position where the snap-in member 7 is disposed. A groove 74 may be formed.

  The groove cover 5 is arranged so that a pair of inverted guide-shaped inclined guide pieces 73 of the snap-in member 7 are inserted into the groove frame 43 of the rafter decorative material 4, and the cover substrate 61 is strongly pressed from the surface side. Then, by pushing the pair of bent ridges 72 into the screw housing groove of the groove frame 43, the pair of rafter decorative materials 4 is inserted into the one locking groove 74 by the pair of laterally-shaped V-shaped grooves. The end of the locking protrusion 44 is elastically locked, and intermittent snap-in mounting is applied in the longitudinal direction of the rafter decorative material 4 to close the groove frame 43 forming the screw storage groove. As a thing.

  Accordingly, the rafter decorative material 4 is provided with screws 45 laterally from the groove frame 43 with respect to the screw receiving ridge 15 of the rafter 1 so that the lower surface of the pair of suspending ridges 14 in the rafter 1 is closed by the decorative substrate 41. It is screwed in and fixed to the rafter 1, but the groove frame 43 is closed so as to be sealed by snapping the groove lid 5 onto the groove frame 43 of the rafter decorative material 4 in the fixed state. Thus, exposure of the screw 45 to the screw receiving strip 15 can be prevented.

  As a result, the groove frame 43 of the rafter decorative material 4 has an appearance closed by the groove cover 5 made of an aluminum extruded material. The groove frame 43 and the groove cover 5 are formed at intervals of 5 and 6 cm at a pitch of 50 cm. Since the snap-in locking is performed and the mounting is performed, it is easier to mount than the snap-in locking of the entire length of the groove lid, and from the longitudinal end of the groove lid 5 where the snap-in locking is not performed. If a slotted screwdriver or the like is inserted, the groove lid 5 can be easily removed with little plastic deformation by grasping the end portion and peeling off the groove lid 5. Since almost no deformation occurs, it is possible to ensure a good fit when reattached.

  In the figure, reference numeral 63 denotes a cover in the groove cover body 6 so that the snap-in-attached groove cover 5 is flush with the tip of the groove frame 43, that is, the tip of the upper protruding piece of the guide rail 42 and the L-shaped cover 16. The step part arrange | positioned at the substrate 61 width direction back surface both ends is shown.
