Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structure for roofing using large-sized roof tiles.

[Conventional technology]

The roof tile used for roofing construction is a ceramic roof tile made of cement, clay, etc. It was fixed on the roof ground.

[Problems of conventional technology]

However, while small tiles have the advantage that roofing can be performed in response to changes in the roof shape and roof area, the number of roof tiles used on the roof surface is large, and there is a problem that it requires labor and time. It has been considered to perform roofing using a long-sized large plate tile that is twice or more the size of conventional tiles. However, since such a large-sized roof tile is heavy, the conventional roof tile fixing structure cannot stably secure the roof tile to the roof surface, and a new fixing structure is required.

[Problems to be solved by the device]

The present invention has been made in view of the above demands, and has an object to provide a roofing structure capable of firmly fixing a large-sized roof tile to a roof surface.

[Technology that has solved the problem]

That is, in the large tile roofing structure of the present invention, the vertical bars located in the roof flow direction are arranged at predetermined intervals on the roof ground,
On the upper surface of this vertical rail, and at a place corresponding to the overlapping portion of the upper and lower large tiles, a fastening metal fitting is formed by bending a wing piece in the roof flow direction at the upper end, and the wing piece of this metal fitting is fixed. Is engaged with each of the upper and lower plate tiles in an overlapping state, and these tiles are fixed to the roof ground,
A sealing material is filled in the required joint gap formed in the joint portion of the large plate tiles adjacent to each other on the left and right, and a drainage member in the form of a paste is attached to the lower surface of the joint portion on the ground between the vertical crosspieces. It is characterized by

〔Example〕

 Next, an embodiment of the present invention will be described.

FIG. 1 is a sectional view of a roof tile fixing portion according to the embodiment of the present invention, and FIG.
FIG. 3 is a perspective view of a metal fitting used for the roof tile fixing portion, FIG. 3 is a sectional view of a roof tile joint portion of the embodiment, and FIG. 4 is a sectional view of an eaves tip portion of the embodiment.

The large plate roofing structure of this invention uses a long and large ceramic tile 1 and vertical bars 2 located in the roof flow direction are arranged on a roof plate 3 at a predetermined interval. At the upper surface of the vertical rail 2 and at a position corresponding to the overlapping portion of the upper and lower large-sized roof tiles 1 and 1, a fastening metal fitting 6 is formed by bending the wing piece portions 4 and 5 in the roof flow direction at the upper end. One wing piece 4 of the metal fitting 6 is fixed by the nail 7, and is engaged with the lower surface side cutout portion 8 of the upper plate slab 1 in the overlapping state, and the other wing piece 5 is the lower plate. The roof tiles 1 and 1 are fixed to the roof base plate 3 by being engaged with the upper surface cutouts 9 of the roof tile 1. Also,
The upper stage large plate tile 1 has an engaging step portion 10 formed on the lower surface of the tip, and this step portion 10 is overlapped with the roof end of the lower plate tile 1 to be engaged with the sealing material 11 at the engaging portion. The roof tile overlapping part is sealed by interposing it. A joining gap 12 of about 5 mm is provided at the joining portion of the large plate roof tiles 1 and 1 that are adjacent to each other on the left and right.
On the other hand, a backup material 13 and a sealing material 14 are filled, and a drainage member (metal gutter) 15 in the form of a paste is attached to the bottom plate 3 between the vertical bars 2 and 2 at the lower part of this joint. Holding member attached to the vertical bar 2
Fixed by 16,16.

Furthermore, at the eaves end, metal fittings 6 are fastened to the large version tile 1
Using the cutout portion 8 with which the wing piece portion 4 of
By engaging the bent portion 19 of the eaves-holding metal 18 which is nailed 17 to the tip of the, the tip of the large plate tile 1 at the eaves is fixed. In addition, 20 is a waterproof sheet that is covered with the base plate 3.

[Action]

According to the above-mentioned structure, each large-sized tile 1 is fixed to the roof surface by engaging the metal fittings 6 fastened to the vertical rails 2 at the tip thereof, so that the conventional direct nail of the tile is used. In addition to increasing the fastening strength of roof tiles as compared with nailing, since nailing construction is not adopted, there is no leakage of rain from nailing parts,
No cracks in the foot. Further, in the case of the large plate roof tile 1, a change in dryness and humidity or a dimensional change due to heat shrinkage are likely to occur, but this can be absorbed by the gap 12 provided at the joint portion between the roof tiles, and even if a sealing break occurs in that case, Rainwater is received by the drainage member 15 immediately below it and can be reliably drained. Further, since a ventilation gap corresponding to the thickness of the vertical crosspiece 2 is formed between the large plate tile 1 and the base plate 3, it is possible to prevent frost damage, soot leakage, and rain leakage.

〔effect〕

Since the present invention is configured as described above, the large plate roof tile can be securely fixed to improve the durability, and the dimensional change occurring in the large plate roof tile can be absorbed while ensuring the waterproof property. Have the effect of.
