Abstract

PURPOSE: To improve the workability of the mounting of a roof tile by forming a nail section at one end of a rod-shaped member while mounting an engaging section such as a screw, with which an engaging member such as a nut is engaged, and a nail driving section having a diameter smaller than the diameter of the engaging section, on the other end side. CONSTITUTION: When a crown tile 70 and long thin ridge tiles 72 are installed, nuts 18 (18a, 18b) are screwed to a screw 12 and the tiles are fixed, thus preventing the cracking of the tiles. Since the diameter of a nail driving section 14 is made smaller than the screw 12, the nuts 18 can be screwed to the screw 12 from the driving section 14 side, and the nuts 18 need not be screwed previously to the screw 12 while there is no possibility that the tiles are damaged by the driving of the nuts 18 at the time of driving operation. Tiles piled up to sections upper than a clamping jig 19 are fastened by a wire 15 retained to a hole section formed to the nail driving section 14. The jig 19 is fixed firmly to a fixing member such as a ridge piece 75 by a slipping-off stop section 16 formed to a nail section 10. Accordingly, the tiles can be fastened easily and surely without being damaged, and can be executed efficiently.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening jig for fixing various roof tiles to a roof, and more particularly to a fastening jig for fixing crown tiles and the like.

[0002]

2. Description of the Related Art Usually, when constructing a building, the method of fixing the roof tile and the roof tile is a method of filling up with soil and mortar. However, this method had the weak point that it was vulnerable to typhoons and earthquakes. Therefore, tie the wire to the pier or squid and stuff it with wiping soil, etc.
Noshi roof tiles and crown tiles were tightly bound by a headband method, tightly tied with a chidori (raveling), and the wires fastened to the piers were fixed directly to the crown tiles. However, it took time and required skill. Therefore, a strong building member was developed to facilitate the fixing of crown tiles. As an example of this powerful building, a powerful building 1 is shown in FIG. This powerful building 1
Is configured so that the roof tile 3 can be fixed to the pier 2. The roof tile 4 and the cross tile 5 are fixed by the soil 6. In addition, the roof tile 5 may be stacked and fixed in several stages in consideration of aesthetics and the like.

Next, in a method for fixing a roof tile, a sleeve tile, an eave tile, etc., a dragonfly in which a wire is wound around a nail (a wire having a required length is tied to a hitting portion formed at one end of the nail) There is a method to fix it with what is called a part to bind the roof tiles together. As an example of this dragonfly, FIG. 16 shows a dragonfly 9 in which a copper wire (wire) 8 is wound around a nail 7. An example of using a dragonfly is a method in which nails are driven up to the striking part at the required position, which is positioned according to the roof tile before it is roofed, and the knotted wire is tightly connected through the tight hole of the roof tile.
As a problem, before laying the roof tiles, the position where the dragonfly is to be hit must be decided, and the position where the roof tiles are laid and the position where the wires are tightly attached are slightly deviated from each other, and it is not possible to fix them properly. In particular, eaves tiles and sleeve tiles are not allowed to have a gap between the tiles when the tiles are fixed side by side in appearance, and the skill of the worker is required. Therefore, a method of directly fixing the roof tile with a nail was born. In this method, tiles are first laid down, the position is determined, and then nails can be hammered in and tightened without moving the tiles, and the skill level of tightening using the dragonfly is no longer necessary.

[0004]

However, the roof tile,
In the method of fixing the roof tiles, when the roof tiles are piled up like a large building, it is necessary to fill them with soil, mortar, etc. It was necessary to be tied up. In this way, the use of soil and mortar could not eliminate the trouble and skill. Further, when the strong building 1 was used, there were problems in cost and convenience due to the use of the strong building 1, and it was necessary to properly use the building depending on the type of building, and the construction complexity increased.

Further, in the method of fixing the roof tiles, sleeve tiles, eave tiles, etc., if the force of the operator is not enough when driving the nails, the tiles are often damaged and it is difficult to fix the tiles with a constant pressure. It was Therefore, as a method of fixing the roof tiles with a constant pressure, it is conceivable to tighten the roof tiles with wood screws, but the work of screwing in the wood screws one by one was enormous and it was not practical. In this way, there are various methods for fixing roof tiles even when roofing one roof, and proficiency cannot be excluded, increasing the complexity of construction.

Therefore, the present inventor has accomplished the present invention as a result of earnest studies to solve such problems.

[0007]

The fixing of the roof tiles by the fastening jig thus performed can be applied to any roof tiles such as crown tiles, cross tiles, sleeve tiles, eaves tiles, and roof tiles forming a ridge. By forming the screw portion, the roof tile is fixed to the ridge or the like by using the soil mortar or the like, but the tile can be securely fixed by using a member in place of it. In addition, it is a method of locking the snow stop fence, but this uses a fastening jig with a long screw part and strikes the fastening jig in the nail hole of the roof tile with the fastening jig like directly locking the roof tile with nails. Insert the nut and fix it at a constant pressure. The long screw part is protruding over the surface of the roof tile, and the snow stop fence is set there at the desired height according to the length of the screw, and it is fixed by sandwiching it with a nut. In this way, in addition to fixing roof tiles, the screw portion can be used for various new applications. If the outside diameter of the nail is large due to the thread molding method,
There may be various cases where the thread diameter is large, but there is no problem. In addition, the length of the fastening jig as a whole can be easily used instead of the conventional anchor or strong wing for fixing the ridge.

Further, in the fastening jig of the present invention in which the engaging member is a ring-shaped member and the engaging portion has a convex portion for retaining the ring-shaped member, the nail portion is penetrated through the hole of the roof tile and the fixing member is provided.

Be locked. Another roof tile is arranged on the fastening jig to which the wire is locked. The wire is pulled out from the upper surface of the other roof tile by passing through the hole of the other roof tile. The extracted wires are tied together and fastened, and other roof tiles are fixed to the fastening jig. Here, if necessary, a bar-shaped purlin is hung on the holes of other roof tiles,
The extracted wire is tied to this purlin and fastened. In this way, the wire is locked to the wire locking portion, so that another roof tile stacked further above the roof tile fixed by the nut is fixed.

Since the fastening jig having the wire locking portion has the wire locking portion for locking the wire in the hitting portion, it can be used in the same manner as the conventional dragonfly. In addition, the wire locking portion can be formed in various shapes so that the wire can be locked easily as long as the wire can be hit. In other words, if the wire locking part is prevented from being deformed and becoming larger than the screw part root diameter by a method such as selection of an optimal material structure and heat treatment so that the nut can be inserted smoothly, It is also possible to form the various shapes.

Next, the fastening jig of the present invention, which has a retaining portion projecting in the direction opposite to the driving direction in the nail portion, has a retaining portion for preventing the retaining jig so that the roof tile can be fixed more reliably. It can be expected and can effectively deal with the rotation of the fastening jig by tightening the screws. However, the retaining part is a burr when forming the tip of the nail part without needing to make it.
The shape obtained in the process of forming burrs may be effectively used.
