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 to 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', a mounting bolt 5 such as a drill screw is attached 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'and 1'by the above method not only has a bad appearance due to the exposed heads of the mounting bolts 5, but also corrodes the mounting bolts 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, and the end of one mountain portion is bent and formed in an inverted L-shape to project, and the end of the other mountain portion is bent and projected in a substantially 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 which is fixed in advance 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 mountain portion of the folded plate type roof plate which is fixed adjacent to the folded plate type roof plate are substantially 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 just one tightening operation, it will be necessary to repeat the further tightening, so labor and time are required, and work efficiency is poor and a special device for tightening 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 that constitutes the strength part of the roof plate is steel, rust will occur very easily, so this is not desirable work. It was

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art and allows a long roof plate to be easily and reliably placed in a predetermined position without time-consuming and time-consuming fastening. The roof plate can be fixed efficiently, and the roof plate can be fixed in a state where the roof surface of the building is excellent in appearance and has excellent water leakage resistance without exposing the mounting bolts to the outer surface. The challenge is to provide a method.

[0007]

As a result of various studies to solve the above problems, the present inventor can easily position the roof plate at a predetermined position and can fix the roof plate by a simple operation. In order to fix to the roof plate, it is effective to fix the roof plate to the roof plate fixing member with the mounting bolts at the overlapped side parts of the roof plates that are fixed adjacent to each other. Paying attention to the fact that it can be done, a long roof plate in which the engaging portions are formed on both sides of the roof plate main body through the stepped portion is overlapped with the engaging portions of the adjacent roof plates. The roof plate is arranged on the roof plate fixing member, and the cap fittings having a width wider than that of the engaging part are formed such that the locking parts formed at both end edges thereof project laterally from the engaging part of the roof plate. Place it on the engaging part of the From the front side of the cap attachment to the engaging portion of the cap attachment and the roof plate, and screwed to the roof plate fixing member, and the substantially cylindrical engagement pieces bent to the back side at both ends. If the engaging pieces of the formed cap are pressed against the locking pieces on both sides of the cap mounting tool while being strongly pressed against the locking pieces of the cap mounting tool, the mounting bolts can be attached to the roof. The present inventors have completed the present invention by clarifying that it is possible to efficiently fix a roof plate in a state in which the roof plate is not exposed to the surface and is fastened without being tightened.

The outer diameter of the engagement piece, which is formed in a substantially cylindrical shape as the cap, is smaller than the gap between the locking piece of the cap attachment and the roof plate main body. By using a cap in which the distance between the engaging pieces is narrower than the distance between the end edges of the locking pieces of the cap attachment, the cap can be securely and firmly fitted onto the cap attachment. As a cap attachment, a cap formed with locking pieces that are inclined toward the roof plate main body side on both sides of the main body with a width that approximately matches the gap between the two ends of the roof plate engaging portion By using the fixture, the cap fixture can be simply and reliably regulated so that its central position matches the central position of the engaging part of the roof plate simply by placing it on the engaging part of the roof plate. Not only can you install the cap of the cap It is also to that investigation that can be implemented easily and reliably fitted work on.

[0015]

When the method of the present invention as described above is carried out, the roof plate 1 is positioned at a predetermined position by overlapping the engaging portions 1b, 1b formed on the side portions,
The cap attachments 2 are placed on the engagement portions 1b at predetermined intervals, and the attachment bolts 5 are passed through the engagement portions 1b and the cap attachments 2 of the roof plate 1 and screwed to the roof plate fixing member 4. By doing so, the roof plate 1 can be fixed to the roof plate fixing member 4, so that the roof plate can be easily and reliably and efficiently fixed to the roof plate fixing member 4 without performing troublesome and time-consuming fastening. be able to.

Then, the cap attachments 2 project laterally from the engaging portion 1b of the roof plate 1 on both sides of the flat main body 2b having a width matching the space between both ends of the engaging portion 1b of the roof plate 1. When the locking piece 2a is formed in a shape that is inclined toward the roof plate main body 1a side toward the side edge, the engaging portion 1b of the roof plate 1 is formed.
By simply placing the cap attachment 2 on top of the cap attachment 2 in the width direction, the engaging portion 1b of the roof plate 1 can be easily and securely attached.
And the central position of the cap mounting tool 2 coincide with each other, and the locking portion 2a of the cap mounting tool 2 is aligned in a straight line with respect to the longitudinal direction of the engaging portion 1b of the roof plate 1 simply and reliably. In addition, the function of the guide portion of the engaging piece 3a of the cap 3 fitted onto the cap mounting tool 2 is formed in a shape inclined toward the roof plate main body 1a side toward the side edge. Since the locking piece 2a is formed, the work of fitting the cap 3 onto the cap attachment 2 becomes easy.

In this manner, the cap attachment 2 fixed to the roof plate fixing member 4 together with the roof plate 1 on the engaging portion 1b of the roof plate 1 has the locking portions 2a formed on both side edges. 1
Of the cap 3 is formed in a substantially cylindrical shape so that the outer diameter of the engaging piece 3a is between the engaging piece 2a of the cap attachment 2 and the roof plate body 1a. Is smaller than the gap between the engaging pieces 3a on both sides, and the gap between the engaging pieces 3a on both sides is smaller than the width of the cap attachment 2, that is, the distance between the end edges of the locking pieces 2a of the cap attachment 2. For example, when the engaging pieces 3a of the cap 3 are strongly pressed while being in contact with the locking pieces 2a on both sides of the cap attachment 2, the spring action of the cap 3 widens the gap between the engaging pieces 3a and the cap 3a. When passing through the edges of the locking pieces 2a on both sides of the fitting 2, the spring action narrows the gap between the engaging pieces 3a of the cap 3 so that the edges of the locking pieces 2a of the cap fitting 2 are on the back surface of the cap 3. The abutment pieces 3a of the cap 3 come into contact with the locking pieces 2a of the cap attachment 2 respectively. In this state, the cap fitting 2 is positioned between the locking piece 2a and the roof plate main body 1a of the roof plate 1.

The engaging piece 3a of the cap 3 is attached to the cap fitting 2
The work of externally fitting the cap 3 to the cap attachment 2 by pressing it strongly with the locking pieces 2a on both sides of the cap attachment 2 fixed in the longitudinal direction of the roof plate 1 is performed. 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. Absent.

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.
