Abstract

<P>PROBLEM TO BE SOLVED: To repair a deteriorated folded plate roof at lower cost. <P>SOLUTION: Fittings 7 are mounted on a ridge along a joint 5 between folded plates nearly at specified intervals and an elongated cover plate 8 is mounted on the ridge through the fittings 7. The mounting fitting 7 is a sheet of a metallic plate bent to be brought into close contact with a ridge part of the folded plate and both shoulders are projected outward to form a V shaped protruded part 7a. The cover plate 8 is a sheet of plate bent to enclose the fittings 7 having V shaped holding parts 8a, and its skirt parts 8b are formed along the folded plate 1. A central part 8c of the cover plate has an arch or tunnel shaped cross section and a bolt 4 or 6 is stored therein. The V shaped holding part 8a is fitted to the V shaped protruding part 7a and is not removed by putting the cover plate 8 on the mounting fitting 7 in a way to open a mouth of the cover plate 8. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a technique for repairing a folded-plate roof that has deteriorated over time.

  As roofing materials for factories and warehouses, steel folded plates with a W-shaped (or V-shaped) cross section are widely used. This type of folded-plate roof has folded-plate seams at the ridges, which tend to hurt and cause leaks. As a method of repairing such a folded-plate roof, it is common to leave a damaged roof as it is and then to lay a new folded-plate roof on it, but this method uses a lot of materials and is expensive. . Therefore, as shown in FIG. 4, a method of screwing the cover plate 18 along the ridge is also used, but new corrosion occurs from the screw hole, and it does not last long.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a folded-plate roof repair fitting that is simple, inexpensive and long-lasting.

  The folded metal roof repair bracket according to the present invention includes a mounting bracket fixed to the folded roof ridge at a distance from each other, and a long cover plate that covers the folded roof ridge via the mounting bracket. Become. The mounting bracket is formed by bending a single plate and has V-shaped protrusions on both sides when viewed in cross section. On the other hand, the cover plate is also formed by bending a single plate, and has a V-shaped holding portion that fits into the V-shaped protrusion of the mounting bracket.

  When using, first fix the mounting bracket to the ridge of the folded-plate roof with screws, and then sandwich the mounting bracket so that the mouth of the cover plate is widened. The holding part fits into the V-shaped protruding part of the mounting bracket. Fixed together. Thus, the cover plate attached along the ridge can completely cover the seam (overlapping portion) of the folded plate and prevent rain leakage. This material uses little material, is easy to construct, and has the effect of being able to repair a folded roof at a low cost.

  First, the existing folded-plate roof will be described with reference to FIG. 1. In the building, beams 2 supporting the roof are arranged at intervals of several meters, and these are W-shaped steel folded plates 1 on the beams, The side edges are supported so as to overlap each other. A tight frame 3 is placed on the beam 2, and the folded plate 1 is penetrated by a sword tip bolt 4 extending upward from the tight frame, and is fastened with a nut. When the folded plate to be used is W-shaped, a folded plate seam 5 is formed every other mountain (in the case of V-shaped, each mountain). The overlapping portions of the folded plates are tightened with the tightening bolts 6 arranged at intervals of several tens of centimeters so as not to leak from these joints.

  However, with such a folded plate roof, as the years pass, the folded plate is corroded at the bolt penetration portion, and rain leakage is likely to occur. In order to repair a damaged roof, in the present invention, the mounting bracket 7 is attached to the ridge having the folded plate joint 5 at a substantially constant interval, and the long cover plate 8 is attached via the mounting bracket.

  As shown in FIG. 2, the mounting bracket 7 is formed by bending a single metal plate so as to be in close contact with the ridge portion of the folded plate, and both shoulders protrude outward to form a V-shaped protruding portion 7a. The hem 7b has a shape along the inclination of the folded plate. The mounting bracket 7 is fixed to the crest of the folded plate with a tap screw 9.

  On the other hand, the cover plate 8 is also formed by folding a single plate so as to wrap the mounting bracket, and has a V-shaped holding portion 8a that fits into the V-shaped protruding portion 7a of the mounting bracket. 8 b is adapted to follow the folded plate 1. The central portion 8c of the cover plate has an arch or tunnel-like cross section in which the bolt 4 or 6 is accommodated. When the cover plate 8 is put on the mounting bracket 7 so as to spread the mouth as shown by a chain line in FIG. 2 (B), the V-shaped holding portion 8a is fitted to the V-shaped protruding portion 7a of the mounting bracket. It will not come off. The cover plate is fixed to the mounting bracket using the tap screw 10. The eaves side end of the cover plate 8 is closed with a non-illustrated mekura plate, and the opposite end is covered with a building plate. In this way, the joint (overlapping portion) of the folded plate 1 is completely covered with the cover plate 8, and rain leakage can be prevented.

  As shown in FIG. 1, the sword bolt 4 protrudes from the ridge without the seam 5, and there is a risk of rain leakage from here. However, since the number of bolts is small, here, as shown in FIG. 3, the construction is sufficient to cover the bolt 4 with a waterproof cap 11 filled with a caulking agent. Of course, the cover plate can be attached in the same manner.

Claims (1)

It consists of a mounting bracket that is fixed to the ridge of the folded-plate roof at a distance from each other, and a long cover plate that covers the ridge of the folded-plate roof via these mounting brackets. The mounting bracket folds a single plate. It is formed along the ridge and has a V-shaped protrusion when viewed in cross section on both sides, and on the other hand, the cover plate is also formed by bending a single plate, A repair metal fitting for a folded plate roof having a V-shaped holding portion that fits into the V-shaped protrusion of the mounting bracket.
