DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a repair structure for a tiled roof in a building.

[0002]

2. Description of the Related Art A tiled roof (1) used for a roof portion of a building such as a factory is, for example, shown in FIGS.
As shown in FIG. 2, a field board (3) is placed on the purlin (2), and a plurality of strip-shaped metal roof boards (4) are placed on the field board (3) via asphalt roofing (not shown). ) Are arranged in parallel. Further adjacent roof panels (4)
A fishing tackle (5) is interposed therebetween, and the corresponding both-side rising pieces of the adjacent roof plate (4), the both-side pieces of the fishing tackle (5), and the covering plate arranged so as to cover them. (6)
Are connected to each other by a standing seam joint, whereby the tile bar portion (1a) extends between the adjacent shingles (4).
Is provided in a rising shape to form a tiled roof (1).

[0003] Such a tiled roof (1) may become defective due to long-term use, and may cause problems such as rain leaks. Therefore, it is desirable to repair the roof at an appropriate time.

For example, in the method of repairing a roof with a tiled roof disclosed in Japanese Utility Model Publication No. 6-35007 and Japanese Utility Model Publication No. 7-35955, first, a filler (11) is inserted into a concave groove of each tile rod portion (1a). ) And each roof slab (4)
A heat insulating material (12) is arranged between adjacent tile rod portions (1a) (1a) on the upper side. Subsequently, a sheet joining plate (13) made of a resin-coated steel plate (PVC steel plate) having a synthetic resin layer on its surface is arranged at a required position on the heat insulating material (12), and a tapping screw (14) is attached to the sheet joining plate ( 13) penetrate through the heat insulating material (12), the roof plate (4) and the base plate (3), and are fixed to the purlin material (2). Subsequently, a waterproof sheet (15) made of a synthetic resin is stretched over the filler (11) and the heat insulating material (12) on the tiled roof (1), and is placed in that state. ) Is fixedly joined to the sheet joining piece (13) by heat fusion or solvent welding. This completes the renovation of the tiled roof (1).

[0005]

However, in the above-mentioned conventional method of repairing a tiled roof, a tapping screw (1) is used.
According to 4), since the sheet bonding plate (13) is fixed on the heat insulating material (12), the screwing work, that is, the fixing work of the sheet bonding piece is very troublesome, and repair work is difficult. I have a problem.

In the above-mentioned conventional repair method, since the screws (14) for fixing the sheet joining plate are made to penetrate through the roof component such as the roof plate (4), the screws (14) are fixed. If it starts to rain before the waterproof sheet (15) is laid, there is a risk that rainwater may enter through the screw holes. In other words, if it starts to rain during the renovation work, it will hinder the renovation work, so it is possible to proceed with the renovation work not only during rain but also in cloudy skies and other conditions where rain will likely start. Did not. Thus, there is a problem that the construction work cannot be performed efficiently because the restrictions on the construction are severe such as being easily affected by the weather.

Further, if the waterproof sheet (15) is damaged after the repair work is completed, there is no undeniable possibility that rainwater enters from the damaged portion of the sheet and leaks from the screw holes, and the waterproofness is not reliable. There was also a concern about a decline in sex.

An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a renovation structure of a tiled-roofed roof which can obtain sufficient reliability regarding waterproofing and can be installed efficiently and easily. Aim.

In the renovation structure of a tiled roof according to the present invention, a roofing cap provided with a sheet joining portion is externally fitted to a tile stick portion, and a waterproof sheet is joined to the sheet joining portion of the cap. It is. For this reason, the sheet joining portion for fixing the sheet can be formed on the roof by a simple operation of merely fitting the roof tile cap to the outside. Therefore, unlike the conventional method in which the sheet joining plate is attached by a troublesome operation such as screwing, the sheet joining portion can be easily formed.

Further, in the present invention, since the sheet joining portion is formed without using a fixing tool such as a screw, a screw hole is not formed in the roof component. Therefore, even if the waterproof sheet may be damaged, it is possible to reliably prevent water leakage due to the screw holes, and to obtain perfect waterproofness.

Further, in the present invention, since no through hole such as a screw hole is formed in the roof component material, even if rain starts to fall before the waterproof sheet is laid during the repair work, the screw hole is not formed. There is no leakage, cloudy sky etc.
Even if it is about to start raining, repair work can proceed until it actually begins to rain.

On the other hand, in the present invention, the following configuration can be suitably adopted.

That is, in the present invention, a sheet joining piece having a synthetic resin surface layer provided on at least the surface thereof is attached to the outer surface of the intermediate wall of the cap body, and the surface layer of the sheet joining piece is attached to the sheet joining portion. The cap body is formed as a resin-coated metal plate having a synthetic resin surface layer laminated on at least a part of its surface, and the cap body surface layer is formed as the sheet bonding portion.
