Description

  The invention of this application relates to a roofing structure and a resin roof that are useful when roofing the upper resin roof tile with the rear end of the lower resin roof overlapped.

  Conventionally, in order to ensure wind resistance when roofing tiles, measures have been taken to prevent the blowing of wind to the back of the tile so that the tile does not rise due to the wind, or to firmly fix the tile itself. Various proposals have been made (see, for example, Patent Documents 1, 2, and 3).

  However, none of the conventional techniques described in these patent documents considers the lifting force due to the air flow flowing on the tile surface. That is, even if the blowing to the back surface of the roof tile can be suppressed or firmly fixed, the roof tile can easily be lifted by the lifting force caused by the turbulent air flow generated on the roof surface. In addition, depending on the construction condition, air may flow into the back of the tile, and eventually a synergistic effect of the lifting force from the back of the tile and the lifting force of the roof of the tile will work, making it easier for the tile to lift up. . In particular, for lightweight resin tiles, it is necessary to consider lifting measures more carefully.

  Therefore, the inventor of the invention of this application forms an air flow path (5) between the resin roof tile (1) and the roof base material (2) such as a field plate, for example, as illustrated in FIG. Further, the present inventors have found a roofing structure with high wind resistance, in which horizontal reinforcing ribs (11) are provided on the back surface of the resin roof tile (1). According to this, when the air A enters and flows through the back surface of the resin roof tile (1) through the air flow path (5), the reinforcing rib (11) generates the circulatory B and generates downward stress. The pulling force (also called tensile force) F on the back surface of the roof tile (1) becomes F, and the lifting force F can effectively suppress the lifting of the resin roof tile (1).

The roof tile structure will be further described. For example, as illustrated in enlarged views in FIGS. 7A and 7B, the rear end rib (12) is first formed along the longitudinal direction of the rear end portion of the lower resin roof tile (1). In addition, a screw hole (13) is provided at a position on the ridge side of the rear end rib (12), and the lower resin tile (1) is placed on a roof base material (2) such as a field plate. Then, the fixing bracket (3) is attached so as to straddle the rear end rib (12), and the fixing screw (4) is inserted into the resin roof tile (32) from the screw hole (32) provided at the rear end of the fixing bracket (3). By screwing into the roof base material (2) through the screw holes (13) of 1), the rear end portion of the lower resin tile (1) is fixed to the roof base material (2) together with the fixing bracket (3). Subsequently, as illustrated in FIG. 6, the upper resin roof tile (1) is placed so that the tip portion thereof is hooked on the hook portion (31) provided at the tip of the fixing bracket (3). After that, by repeating these series of operations, resin tiles (1) are piled up from the eaves side to the building side.

  However, even in the roof tile structure that achieves excellent wind resistance as described above, the relationship between the fixing metal fitting (3) and the rear end rib (12) of the resin roof tile (1) used in this application is described in this application. As a result of further investigation by the inventor of the present invention, the occurrence of thermal expansion and contraction of the resin roof tile (1) is considered in actual use. At this time, for example, as shown in FIG. When 1) expands or contracts in the eaves direction, or the lower resin roof tile (1) expands or contracts in the building direction, or both of them occur, the rear end ribs (1) of the lower resin roof tile (1) ( There was a concern that 12) would undergo unreasonable deformation under stress from the straddle portion (33) of the fixture (3).

  Therefore, in view of the circumstances as described above, the invention of the present application prevents the rear end rib (12) from being forcedly deformed even if it receives stress from the straddle portion (33) of the fixing bracket (3). It is an object to provide a roofing structure and a resin roof.

  In order to solve the above problems, the invention of this application is as follows. First, a fixing bracket is attached so as to straddle the rear end rib provided on the lower resin roof, and the upper resin roof is interposed through the fixing bracket.

[First Embodiment]
1 and 2 (a) and 2 (b) each show an embodiment of the invention of this application.

  In this embodiment, first, like the conventional roof tile structure found by the inventor of the present invention described above, the fixing bracket so as to straddle the rear end rib (12) provided on the lower resin roof tile (1). (3) is attached, and the top end of the upper resin tile (1) is overlapped with the rear end portion of the lower resin roof tile (1) via the fixing metal fitting (3) (see also FIG. 6). ). More specifically, the rear end ribs (12) provided on the lower resin roof tile (1) when the upper resin roof tile (1) is overlapped with the rear end section of the lower resin roof tile (1) and tiled. ) Is fixed so that the rear end portion of the lower resin tile (1) is screwed to the roof base material (2) through the fixing bracket (3) and the upper resin tile (1) ) The front end is fixed to the lower end of the resin roof tile (1).

  In such a roofing structure, as described above, it is considered that when the resin roof tile (1) is thermally expanded and contracted, the rear end rib (12) receives stress from the straddle portion (33) of the fixing bracket (3). It is done.

  Therefore, in order to cope with this stress, when the rear end rib (12) of the resin roof tile (1) receives stress from the straddle portion (33) of the fixing bracket (3), an elastic portion that can be deformed by the stress is provided. It has become.

  Thus, by providing a deformable elastic portion in the rear end rib (12) in advance, the resin roof tile (1) is temporarily expanded and contracted, and accordingly the straddle portion (33) of the fixing bracket (3) is positioned. Even if stress is applied to the rear end rib (12) in contact with the straddle portion (33) due to the fluctuation, the elastic portion receives the stress and performs a pre-determined deformation. The occurrence of this can be effectively suppressed. The stress (see FIG. 8) applied to the hooking portion (31) of the fixture (3) can also be reduced.

  More specifically, the elastic portion in FIG. 1 is configured by a rib piece (121) having a vertical gap groove (121a) at a position spaced from the left and right fixed ends. It can also be said that it is composed of a pair of rib pieces (121) facing each other with a gap groove (121a) provided at a substantially central position therebetween. The fixing bracket (3) is attached so that the straddle portion (33) straddles the entire rib piece (121) together with the gap groove (121a) (see FIG. 2A), and the position of the straddle portion (33) varies. It can be deformed back and forth in accordance with the stress received by.

  In addition, the rib piece (121) in FIG. 1 has a width W corresponding to at least the width of the straddling portion (33) straddling it.

  Further, the rib piece (121) has at least the straddling portion (33) such that when the straddling portion (33) is straddled, the upper surface thereof is substantially the same height as the upper side of the rib piece (121) or lower than the upper side. ) Has a height H lower than the rear end ribs (12) on both sides. With respect to this height shape, the rib piece (121) in FIG. 1 has a shape that is recessed from the surroundings (it can also be said that it has a recessed portion). For example, as illustrated in FIGS. Further, the upper sides of the rear end ribs (12) on both sides may be inclined and gradually lowered. In FIG.2 (b), the upper surface of the straddling part (33) and the upper side of the rib piece (121) are substantially the same height.

[Second Embodiment]

  According to this double rib piece (122), when stress is received from the straddling portion (33), the first rib piece (122a) and the second rib piece (122b) move back and forth to release the stress, and the rear end Forcible deformation of the rib (12) can be prevented.

  This double rib piece (122) also has a width W corresponding to at least the width of the straddling portion (33), and more than the rear end ribs (12) on both sides by at least the thickness of the straddling portion (33). It has a low height H. With respect to this height shape, the double rib piece (122) is recessed from the surroundings in FIG. 3 (it can also be said to have a recessed portion). For example, as illustrated in FIG. The rear end rib (12) on the fixed end side of each of the rib piece (122a) and the second rib piece (122b) may be inclined and gradually lowered.

[Third Embodiment]
Further, the elastic portion of the rear end rib (12) is constituted by a long rib piece (123) having longitudinal gap grooves (123a) (123b) at the left and right fixed ends, as illustrated in FIG. 5, for example. It can also be made.

  According to this long rib piece (123), due to the presence of the half-gap grooves (123a) (123b) located on both sides of the long plate, the upper half is bent back and forth due to the stress from the straddling portion (33). As a result, stress can be relieved by this deformation to prevent excessive deformation of the rear end rib (12).

  Unlike the first to fourth rib pieces (121) and the double rib pieces (122), the long rib piece (123) is a long plate body, so that it has its own width W and high Instead of being H, it has a barbed recess (123c) having a bar width W and a height H ′ (also called a straddle barb) at a substantially central position. In this case, W is at least the width of the straddling portion (33) and is the same as described above, but H 'is at least the thickness of the straddling portion (33).

[Rear end rib = Waterproof rib]
In addition, about the rear end rib (12) which has an elastic part of the above various shapes and structures, what played the role as a waterproof rib which prevents invasion of rainwater can also be considered, and the rear end rib (12 as this waterproof rib) ), The waterproof performance can be secured even if the deformable structure by the various elastic parts is adopted. In FIG. 1 and FIG. 2, although the gap groove (121a) is provided in the rib piece (121), the straddle part (33) of the fixing bracket (3) is straddled on the rib piece (121a). ) Is not easily reached. 3 and 4, a double rib piece (122) is formed by two separated first rib pieces (122a) and second rib pieces (122b). It is difficult for rainwater to reach between the double rib pieces (122) by the portion (33). Further, in FIG. 5, although the semi-gap grooves (123a) and (123b) are provided at the left and right ends of the long rib piece (123), they are opened to the roots like the gap grooves (121a) in FIG. It is not a thing, and rainwater can be dammed in a lower part rather than a half-gap groove (123a) (123b). Therefore, sufficient waterproof performance can be maintained by any configuration.

  In addition, the half-gap groove (123a) (123b) in FIG. 5 is not limited to the height of exactly half of the long rib piece (123), but has a deformation function and a waterproof function when subjected to stress. It may be less than half or more than half as long as it can be secured.

  Of course, the invention of this application is not limited to the above embodiments, and various aspects are possible for details.

  As explained in detail above, according to the invention of this application, the fixing bracket is attached so as to straddle the rear end rib provided on the lower resin roof tile, and the upper resin roof tip portion is attached to the lower resin roof via the fixing bracket.
