Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal roof plate constituting a roof surface of a building, and ends thereof are overlapped with each other in the width direction, and the roof plate is fixed by mounting bolts at the overlapped portion. In this case, the present invention relates to a method of fixing a roof plate that can easily fix the roof plate in an excellent appearance without exposing the mounting bolt to the roof surface.

[0002]

2. Description of the Related Art Various types of roof plates for buildings have been manufactured by bending a standard or long metal plate. As one method of forming a roof surface of a building, both sides of long-sized roof plates that are fixed adjacent to each other are overlapped, and mounting bolts are penetrated through the overlapped end parts, and a roof plate and a purlin Shows a method of screwing a member or a tight frame fixed to these members (these members may be collectively referred to as a roof plate fixing member) to fix the roof plate to the sideways in sequence. be able to. In this method, for example, as shown in FIG. 7, as a roof plate 1 ', a long folded plate type in which a mountain portion 1b' is formed on both sides of a roof plate main body 1a 'is used. After stacking the ridges 1b ', 1b' formed on both sides of the plates 1 ', 1', attach a mounting bolt 5 such as a drill screw to the ridges 1b ', 1'.
This is a method of penetrating through b'and further screwing and fixing to the lower roof plate fixing member 4. However, the roof surface formed by fixing the roof plates 1 ′, 1 ′ by the above method not only has a bad appearance due to the exposed head of the mounting bolt 5, but also corrodes the mounting bolt 5 and its surroundings. However, there is a drawback that rain is likely to occur.

Therefore, a method has been used in which a long roof plate is fixed to a roof plate fixing member via a suspension so that the mounting bolts are not exposed on the roof surface.

As this method, for example, in order to ensure the locking of the ends of a long roof plate with each other and to prevent water from leaking from the locking part, one or both of the roof plates are locked at the locking part. There is a method of fastening the edges, and as an example of a method of fastening the roof plates made of metal by fastening them, there is a mountain portion that has a portion to be connected by the fastening on both sides of the valley portion at the end. It is formed, the end of one mountain part is bent and formed to project in an inverted L shape, and the end of the other mountain part is bent to project in a generally U-shape with a downward opening. There is a method of using a folded plate type roof plate that is formed. In this method, in order to fix the folded-plate type roof plate to the roof plate fixing member, the inverted L-shaped portion formed at the end of the mountain portion of the roof plate that is previously fixed is formed at a key point. The suspended hangers are fixed to the roof plate fixing member at predetermined intervals, and then the end portions of the other ridges of the folded plate type roof plate that are fixed adjacent to the folded plate type roof plate are formed. After covering the downward opening that is formed to project in a U shape on the folding plate type roof plate that is fixed first (there is a part where the suspenders are locked), the edge Tighten up.

However, the above work is, of course, a work in which a long roof plate is arranged on the roof surface of a building, and the roof plate itself is further tightened over the entire length of the roof plate. If water leakage resistance, wind pressure resistance, etc. are not sufficient with only one tightening operation, further tightening of the ear will be necessary, which requires time and effort, and the work efficiency is poor, and a special device for tightening the ear There was a drawback that it required. When this fastening operation is performed, the metal plate that constitutes the roof plate undergoes strong plastic working at the fastening portion, so the surface of the metal plate that constitutes the roof plate is in contact with the device that performs the fastening process. It has the drawback of cracking or scratching the coating film and reducing the durability of the roof plate, and if the material forming the strength part of the roof plate is steel, rust will occur very easily, so this is not desirable work. It was

It is very easy because it is sufficient to perform only the parts that have

Also, the cap 3 used in the method of the present invention.
Has a high rigidity and is hard to be deformed because the engaging pieces 3a formed at both ends are substantially cylindrical, and thus the upper side, that is, the side opposite to the roof plate, of the cap 3 externally fitted to the cap mounting tool 2. Even if a force is applied to the cap attachment 2, it will not come off from the cap attachment 2. Further, since the gap between both engaging pieces 3a of the cap 3 is formed to be narrower than the width of the cap mounting tool 2, rattling occurs due to the spring action of the cap 3 when the cap 3 is fitted onto the cap mounting tool 2. It has such.

In this way, the cap 3 is the cap attachment 2
When the mounting bolt 5 is externally fitted to the cap 3, the mounting bolt 5 is hidden by the cap 3 to form a roof surface having an excellent appearance in which the mounting bolt 5 is not exposed, and the mounting bolt 5 is hidden by the cap 3. Therefore, the mounting bolts are less likely to be corroded and the service life is improved.

As described above in detail, the roof plate can be fixed by a very simple work, the mounting bolt is not exposed on the roof surface, and the cap is firmly fixed in the cap mounting jig. The method of fixing the roof panel according to the present invention, which is externally fitted, has a great industrial value.
