DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roofing method, and more particularly to a roofing method in which another existing roofing material is laid on an existing corrugated slate roof. .

[0002]

2. Description of the Related Art A corrugated slate is widely used as a roof material for buildings such as factories and warehouses. This waveform slate is
Hook bolts, which are mounted on the upper surface of a purlin girder forming a roof via a laying member, are hooked at predetermined intervals on the purlin girder, and extend upward through the respective chevron tops of the slate. It is supported and fixed by screwing a nut to the existing male screw part. Roofs covered with this corrugated slate are repaired as appropriate due to damage or deterioration over time, but as a means for repairing, the corrugated slate to be replaced and other Remove all hook bolts supporting the corrugated slate from the purlin girder and remove the slate to be replaced before installing a new corrugated slate.

[0003] At appropriate places of the new slate, a through hole for inserting a hook bolt is opened, and the lower part of the hook bolt inserted into the through hole is hooked on the upper part of the purlin girder.
By screwing the nut, the new slate is supported and fixed. However, this method has a drawback that a part of the damaged old slate or dust when removing the old slate falls into the inside of the building from between the purlins and soils the floor and the like. Also, as mentioned above, it is pointed out that a new slate requires a lot of labor and construction cost because it requires time to newly open a through hole for inserting a hook bolt.

As a means for solving this problem, for example, in the invention "Repairing method for an existing roof" according to the application of Japanese Patent Application Laid-Open No. 8-184137, there is a proposal to install a metal plate as a roofing material above a corrugated slate. It has been done. That is, according to this method, a metal purlin support member is installed on the corrugated slate at predetermined intervals, and the purlin is installed on the purlin support member. A perforated hole is formed on the upper surface of the purlin support member so as to correspond to a loose hole formed in the purlin, and a fixing screw that passes through the loose hole and the perforated hole to the waveform slate is screwed. By inserting, the purlin is fixed to the purlin supporting the waveform slate. In addition, a roofing member fixing member is attached to the purlin provided on the upper surface of the purlin support member at predetermined intervals along the longitudinal direction thereof, and the metal plate is disposed via the roofing member fixing member. It has become so.

[0005]

The above-mentioned repair method has an advantage that the waveform slate to be repaired does not have to be removed from the place, and the construction can be simplified accordingly.
However, when arranging the purlin support member on the corrugated slate, it is necessary to newly provide a through hole for inserting the fixing screw into the slate. Problems such as generation of noise and vibration will occur. Further, it is necessary to prepare the fixing screws described above in addition to the existing hook bolts, so that there is a problem that the construction cost is increased.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above-mentioned problems inherent in the prior art, and has been proposed to solve the problem in a favorable manner. It is an object of the present invention to provide a roofing method in which a new roof is laid on the upper surface of an existing waveform slate with almost no noise or noise.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a roofing method according to the present invention. As shown in FIGS. 1 and 3, the structure of the roof to which this method is applied is a through hole formed at an appropriate point of the corrugated slate roof 10 at the top of the chevron.
Hook bolts 12 are inserted through (not shown). The hook bolt 12 has a hook portion bent at an acute angle at a lower end thereof, which is engaged with an upper portion of the purlin girder 14, and an upper portion provided with a male screw portion 12a has a corrugated slate roof 1 having a male screw portion 12a.
The splined roof 10 is supported and fixed to the purlin girder 14 by screwing a nut 17 to the male screw portion 12a via a sponge washer 15 and a turtle washer 16. ing.

As shown in FIGS. 1 and 2, a saddle member 18 is provided on the male screw portion 12a of the hook bolt 12. That is, the saddle member 18 is formed by bending a plate member cut and molded to a required width into a convex shape, so that a pair of locking pieces 20, 20 which are always separated and opposed to each other.
Are formed below, and a chevron-shaped support portion 22 projects upward between the locking pieces 20, 20. The locking pieces 20, 20 have a distance between the two facing hook bolts 1.
The diameter is set to be sufficiently larger than the diameter of the second support 2, and can be deformed in directions approaching each other by the elasticity of the chevron support 22. In addition, the width of the saddle member 18 is set to the through purlin 24 having a channel shape or a hat shape in cross section.
The dimensions are set to be slightly smaller than the inner diameter width of (described later).

The saddle member 18 includes a nut 17 screwed to the hook bolt 12 and the corrugated slate roof 10.
The locking pieces 20, 20 are directed from both sides to a contact portion with the crest 10a. As described above, the nut 17 is attached to the male screw portion 12a of the hook bolt 12 by a sponge washer 15.
And a torsion washer 16. For this reason, as shown in FIG. 3, each locking piece 20 of the saddle member 18 is attached to the sponge washer 15 sandwiched between the tortoise washer 16 and the crest 10 a of the corrugated slate roof 10. Forcibly pressed from the direction along the ten peaks.

The saddle member 18 interposed between the sponge washers 15 is connected to locking pieces 20, 20 via a jig (not shown).
Are forcibly deformed from both sides, so that the open ends 20a, 20a of the locking pieces 20, 20 facing each other are
The sponge washer 15 is forcibly fitted to the sponge washer 15 between the nut 17 and the crest 10a of the corrugated slate roof 10 (FIG. 3B). In this case, since the sponge washer 15 itself is easily collapsed due to aging, it is relatively easily crushed and the intervention of the locking piece 20 is allowed. Therefore, as shown in FIG.
a, 20a arrive at a position close to the male screw portion 12a of the hook bolt 12. The locking piece 2
Prior to pressing and deforming the nuts 0 and 20, an upward and downward expanding force is forcibly applied to a contact portion between the nut 17 and the crest 10 a of the corrugated slate roof 10, so that the nut 17 and the crest 10 a It is also recommended to provide a gap between these and the locking pieces 20, 20 to allow the fitting of the locking pieces 20, 20.

Further, since the material of the tortoise washer 16 is a metal, rust is generated on the entire surface due to aging, but most of the inner portion is not corroded. Even if the locking pieces 20, 20 are fitted, the strength as a support member is sufficiently ensured, and the saddle member 18 is also firmly supported and fixed to the corrugated slate roof 10. The place where the saddle member 18 is pressed by a jig (not shown) is, as shown in FIG.
From the vicinity of the bent portion connected to the chevron support portion 22,
The locking piece 20 is set in the vicinity of a bent portion that is separated in the rotation direction.

The saddle member's chevron support 22 fixed to the crest 10a of the corrugated slate roof 10 by the engagement of the locking pieces 20, 20 has the through purlin made of a long hat member open downward. By attaching 24 from above, the passing purlin 24 is extended in a direction intersecting the crest 10 a of the corrugated slate roof 10. That is, as shown in FIGS. 4 and 5, the through purlin 24 is a long member whose cross section is bent into a hat shape at such a height as to straddle the saddle member 18 and extends in the longitudinal direction. The channel 24b, which opens downward, is formed with flanges 24a, 24a slightly extending left and right in the horizontal direction, and these flanges 24a, 24a abut or approach the peaks 10a of the corrugated slate roof 10. It is supposed to.
Then, the through purlin 24 and the chevron support 22 are fixed by fasteners 26 such as bolts, so that the through purlin 24 is attached to the saddle members 18 located at required intervals along the waveform of the corrugated slate roof 10. Although the through purlin 24 in the illustrated example is a long hat member, the flange 2
It may be a simple channel member without 4a and 24a.

Next, a metal roofing material 28 is laid on the main purlin 24 which is supported by the saddle member 18 and extends in a direction intersecting with the crests 10a of the corrugated slate roof 10. The through purlin 24 is fixed with fasteners 26 such as bolts. As shown in the figure, the metal roofing material 28 is a folded plate in which a trapezoidal projection 28a is formed at a position substantially aligned with the chevron top of the corrugated slate roof 10. The metal roofing material 28 is supported and fixed by screwing in a fastener 30 such as a tapping screw formed to a length reaching at least the upper surface of the through purlin 24. Further, as described above, since the passing purlin 24 is fixed to the saddle member 18 provided on the corrugated slate roof 10 via the hook bolts 12, the metal roofing material 28 is fixed to the passing purlin 24. As a result, the purlin girder 14 is supported and fixed.

FIG. 6 shows a state where the mounting direction of the saddle member 18 is changed. That is, the saddle member 18 in this case is rotated in the direction of 90 degrees about the axis of the hook bolt 12, and the direction in which the locking pieces 20, 20 move across the chevron support 22 is determined. , Along the crest 10 a of the corrugated slate roof 10. Also in this case, similarly to the saddle member 18, the nut 17 screwed to the hook bolt 12 and the peak 10 of the corrugated slate roof 10
The locking pieces 20, 20 are directed from both sides to the abutting portion with a. In this state, the locking pieces 20, 20 are forcibly pressed and deformed from both sides via a jig (not shown), so that the saddle member 18 has the open ends 2 of the locking pieces 20, 20.
0a and 20a are forcibly fitted toward the sponge washer 15 located between the nut 17 and the crest 10a of the corrugated slate roof 10.

Thereafter, by attaching the passing purlin 24 from above, the passing purlin 24 is extended in a direction intersecting the crest 10 a of the corrugated slate roof 10. Then, the through purlin 24 and the chevron support 22 are fixed by the fasteners 26 such as bolts, so that the through purlin 24 is attached to the saddle member 18. Next, the metal roofing material 28 is overlaid on the passing purlin 24 and the roofing material 28 and the passing purlin 24 are fixed with the fasteners 30 such as tapping screws, so that the metal roofing material 28 is corrugated slate. It is overlaid on the upper surface of the roof 10.
