The effects exhibited by the above embodiment will be described below.
In the large ridge 11 having the ridge structure of this embodiment, the core material 31 is erected on the field 14. The core material 31 is fixed on the field 14 by being sandwiched by the core material sandwiching portions 43 of a plurality of pairs of fixing members 41 whose lower ends are opposed to each other. Further, the intermediate portion and the upper end portion of the core material 31 are located in the space 67 and are embedded in the adhesive 68 filled in the space 67. Therefore, the ridge tile 61 is integrated with the core material 31 by the adhesive 68 filled in the space 67 and is fixed on the large ridge 11 while being supported by the core material 31. Therefore, the ridge structure of the present embodiment can firmly fix the ridge tile 61 on the large ridge 11 as compared with the conventional ridge structure, and is strong against earthquakes and strong winds.

  The core material 31 is formed in a lattice shape from a plurality of vertical frame materials 32 and horizontal frame materials 33. For this reason, the core material 31 of this embodiment can increase the adhesion area (contact area) of the adhesive 68 and be firmly integrated with the roof tile 61 as compared with, for example, the case where there is only one horizontal frame member 33. it can. Furthermore, the core member 31 can receive external force applied to the roof tile 61 by the plurality of vertical frame members 32 and the horizontal frame member 33. Therefore, the core material 31 can support the ridge tile 61 more reliably against the external force applied to the ridge tile 61. Furthermore, the core material 31 can be reduced in weight compared with the case where the horizontal frame member 33 is a single flat plate.

  The core material 31 is fixed on the field 14 in a state where the horizontal frame member 33 located at the lower end of the peripheral edge abuts the field 14 and is embedded in the first base 51. For this reason, the core material 31 abuts on the field 14 and suppresses the occurrence of cracks in the first base 51 by receiving the external force on which the horizontal frame member 33 embedded in the first base 51 is concentrated. Can do.

  The core material 31 is sandwiched by being inserted between the core material sandwiching portions 43 of the plurality of pairs of fixing members 41 whose lower end portions are opposed to each other. For this reason, the ridge structure of this embodiment can fix the core material 31 on the field 14 easily.

  -The upper end part of the core material 31 is arrange | positioned between the pair of glazed roof tiles 62 located in the uppermost part. For this reason, the core material 31 can support the roof tile 61 more reliably by reducing the swing of the roof tile 61 due to external force compared to when the upper end of the core material 31 is positioned below the center height of the roof tile 61, for example. it can.

  On the field 14, a plurality of opposing fixing members 41 are attached with an interval of 1 m or the like in the longitudinal direction of the main building 11. For this reason, the plural pairs of fixing members 41 facing each other can fix the core material 31 on the field 14 by holding the lower end portion of the core material 31 at a constant interval.

  ・ Each foundation 51, 64 is formed of plaster. Here, the plaster is harder and stronger than the adhesive 68. For this reason, the ridge structure of this embodiment can fix the ridge tile 61 more firmly than when the ridge tile 61 is attached on the large ridge 11 by the adhesive 68.

  The ridge tile 61 is attached on the large ridge 11 by the first base 51 formed of plaster, and each of the roof tile 62 and the crown tile 66 are joined by an adhesive 68. Here, when a foam adhesive is used as the adhesive 68, the specific gravity of the adhesive 68 filled in the space 67 is lighter than that of plaster. For this reason, the ridge structure of the present embodiment can lower the center of gravity of the ridge tile 61 compared to when the space 67 is filled with plaster. Here, as the center of gravity of the ridge tile 61 increases, the sway by the external force increases. Therefore, the ridge structure of the present embodiment can reduce shaking due to external force compared to when the plaster is filled in the space 67 and can firmly fix the ridge tile 61 on the large ridge 11.

In addition, this embodiment can also be changed and embodied as follows.
-You may form the said large ridge 11 in the side surface circular arc shape in which the center part of a longitudinal direction is dented below slightly. At this time, the core material 31 is formed in a side arc shape in which a central portion in the longitudinal direction is slightly recessed downward. Further, the large building 11 may be changed to a descending or corner building. That is, the building structure of this embodiment may be used for buildings other than large buildings.

The shape of the vertical frame member 32 or the horizontal frame member 33 of the core member 31 may be changed to a round bar or the like. Moreover, you may form the vertical frame material 32 or the horizontal frame material 33 with a timber or a synthetic resin material.
The core material 31 may be constituted by a wire mesh formed by knitting a wire material having a diameter of 1 mm, for example. A square ring-shaped frame member is attached to the periphery of the wire mesh by welding or the like. The wire mesh is fixed on the field 14 by being sandwiched between the core member sandwiching portions 43 of the fixing member 41 facing the lower end of the frame member.

The pair of opposing fixing members 41 may be integrated. That is, the fixing portions 42 may be integrated.
The first base 51 may be omitted. At this time, the pair of bottom tiles 62 facing each other at the bottom is installed on the main building 11 by the adhesive 68. Further, the second base 64 may be omitted. At this time, it is preferable that the pedestal 65 is sandwiched between the lowermost pair of opposing roof tiles 62 and the second pair of facing roof tiles 62 from below.

The ridge tile 61 may be composed of a pair of opposed glazed roof tiles 62 provided on the large ridge 11 and a crowned tile 66 mounted on the glazed roof tile 62.
