Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge core material which is sandwiched between tiles when the tiles are stacked, and the tiles are held in a stackable manner.

[0002]

2. Description of the Related Art Conventionally, in a house having a roof shape such as a gabled roof or a hipped roof, so-called stacking is performed by stacking a roof tile on the top of the roof and placing a roof tile on it. Has been done. In the process of stacking tiled roofs, the soil is piled up on the tiles, the tiles are placed on top of the tiles, and the soil is piled on top of the tiles. The roof tiles were fixed to the roof by tying wires around the roof tiles and binding them.

[0003]

However, in the above-mentioned conventional method, a large amount of soil must be used when stacking a plurality of tile tiles, which is difficult to construct, and the tile tiles are difficult to construct. There was a problem that the weight of the embankment on top placed a heavy burden on the roof. Moreover, since the tile tiles are only tied with wires or the like from the outside in a state where a plurality of tiles are stacked with the embankment sandwiched, there is a problem that the laminated tiles are not completely fixed to the roof.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a ridge core material which is easy to construct and can securely fix a roof tile to the roof. .

[0005]

In order to achieve the above object, the ridge core material according to claim 1 is used for stacking tile roofs and is sandwiched between the tiles. A roof tile holding portion having a fitting groove into which a projection provided on the roof tile fits, and a protrusion protruding from an end of the roof tile holding portion. Has become.

In the ridge core material of this construction, the protrusion provided on the roof tile is fitted in the fitting groove formed in the roof tile holding portion, and the roof tile is sandwiched between the roof tile and the roof tile holding portion of the roof material directly above. Since it is not necessary to pile up the roof tiles with soil, it is possible to prevent the roof from being burdened with a weight and to improve the work efficiency.

According to a second aspect of the present invention, in addition to the structure of the first aspect of the present invention, the projecting portion is formed by laminating a plurality of the case materials in the height direction of the projecting portion. When fixing the core members to each other with screws, a through hole into which the screws are inserted is formed so as to penetrate through the height direction.

In addition to the effect of the invention as set forth in claim 1, in the ridge core material having this structure, the projecting portion is provided with a through hole penetrating in the height direction thereof. The ridge core material stacked in the height direction can be screwed and fixed by being inserted.

According to a third aspect of the present invention, in addition to the structure of the first aspect of the present invention, the lower end of the first aspect of the core material has a plurality of the core materials in the height direction of the projecting portion. It is characterized in that a concave portion is formed for fitting with the projecting portion of the core material immediately below when the individual layers are laminated.

In addition to the effect of the invention described in claim 1 or 2, in the ridge core material having this structure, when a plurality of ridge core materials are laminated on the lower end portion of the ridge core material substantially parallel to the height direction of the projecting portion. In addition, since a recess is formed for fitting to the projecting part of the core material directly below, it is possible to easily stack multiple core materials in the height direction of the projecting part, which improves work efficiency. You can

According to a fourth aspect of the present invention, in addition to the constitution of the first aspect of the present invention, the first aspect of the present invention has a predetermined length in the longitudinal direction of the laying of the ridge. It has a fitting part which can connect a plurality of the core materials in the length direction at both ends thereof.

In addition to the function of the present invention as set forth in any one of claims 1 to 3, the ridge core material having this structure is fitted at both ends in the length direction thereof so that a plurality of ridge core materials can be connected in the length direction. Since the joint portion is provided, a plurality of ridge core materials can be connected and used in the length direction.

According to a fifth aspect of the present invention, in addition to the structure of the first aspect of the present invention, the roof tile holding portion is extended in the left-right direction about the projecting portion. It is characterized by

In the ridge core member having this structure, in addition to the effect of the invention according to any one of claims 1 to 4, since the roof tile holding portion is extended in the left-right direction about the projecting portion, respectively.
Roof tiles can be arranged on both the left and right sides of the protrusion.

By fitting the projecting portions 76 of the ridge core material 75 holding the ridge core material 75, the ridge core materials 75 are laminated. Similarly, if the tile tiles 121 to 123 and the ridge core material 75 are alternately laminated in the same manner, and then the round tile 124, which is a round tile, is fixed to the uppermost portion,
A building 70 is constructed. Further, in the above-mentioned ridge core material 1, if the ridge core material formed by enlarging the linear dimension between the left and right ends of the roof tile holding portion 3 is used, the box ridge 8
Even if 0 is not provided, it is possible to stack multiple tiles with only the core material.

Similarly, when stacking the tiles on the box ridge plate 81 provided outside the box ridge 80, as shown in FIG. 7, the tile holding portion 3 of the ridge core material 1 shown in FIG. 2 is used. The roof tiles 105, 1 are made by using the ridge core material 115 configured on only one side of the
It is also possible to stack 06. In this case, on the upper surface 116a of the roof tile holding portion 116 of the ridge core material 115, the roof tile 1
No. 117 is provided with a groove 117 into which the projection 105a provided at 05 and the projection 106a provided at the roof tile 106 are fitted, and the ridge core material 115 is obliquely penetrated from the bottom of the groove 117. By screwing the wood screw 200 into the core material 115 and further screwing it into the box ridge board 81,
The building core material 115 is fixed to the box building board 81. Then, the projections 105a provided on the roof tile 105 are fitted into the grooves 117 provided in the roof tile holding portion 116 of the ridge core material 115 to stack the ridge core material 115 and the roof tile 105, and further ridges By stacking the core materials 115, it is possible to stack a plurality of Nogami tiles.

Furthermore, the connecting structure in the length direction of the core material is also
As described above, the method is not limited to the method of forming two recesses and two projections at both ends of the core material in the length direction. As shown in FIG. 8, in the length direction of the ridge core material 125, one concave portion 126 having a predetermined width is formed in the upper end portion thereof, and the concave portion 126 is recessed downward in FIG. 8, and the lower end portion thereof has substantially the same width as the predetermined width. The convex portion 12 protruding downward in FIG. 8 by the amount of the concave portion 126.
It is also possible to form one 7 and fit the convex portion 127 of the other core material 125 into the concave portion 126 to connect the core materials 125 in the length direction thereof. in addition,
It is possible to connect multiple core cores in the length direction even if the core cores have no unevenness at both ends in the length direction and the ends have a flat cross section. . Further, in the ridge core material 1 of the present embodiment, through holes are further provided in the intermediate portion of each of the through holes 15 to 19 formed in the projecting portion 2, and the outside and inside of the house are provided by these through holes.
