Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a roof end face wall fitting portion for preventing water from leaking from a space between a roof on a lower floor of a building and an end face wall of an upper floor to an indoor side. .

[0002]

2. Description of the Related Art Conventionally, as shown in, for example, JP-A-60-215936, an inner layer material is laid on a base member such as a purlin,
A mounting member such as rafters is supported on the water leakage prevention plate laid on the inner layer material and fixed on the base member, the roofing material is roofed on the mounting member, and between the roofing material and the water leakage prevention plate, There was a roof with a drainage space that communicated with the opening in the eaves.

Further, the upper edge portion of the rain presser (4) is used as a gable face wall fitting part (3) provided between the roof (1) on the first floor and the gable face wall (2) on the second floor shown in FIG. Is fixed to the end face wall (2), and the lower edge is abutted on the end face side of the roof material (6).
There is a drainage plate provided on the lower surface of the end of the gable surface side, whereby water such as rainwater flowing down the inside and outside of the rain press is drained from the eaves to a gutter (not shown).

[0004]

Generally, in the roof side wall joint portion of the roof, water such as rain water flowing down the outdoor side surface of the upper side roof surface and the upper surface of the roof material on the lower floor joins each other, and rain or Since the wind blows snow onto the gable wall, a large amount of rain and snow is concentrated, so water leaks easily to the indoor side, and like the conventional roof mentioned above, there is a drainage space under the roof material. Even if a water leakage prevention plate is installed, water leakage may occur in the conventional housing of the end face wall joint.

That is, in a conventional roof gabled wall fitting part, due to a manufacturing error of the rain presser, a mounting failure of the rain presser, or the like, the rain presser is overlapped with the lower edge of the rain presser or the upper surface of the roof material. Water such as rainwater enters the inside of the rain presser from the seam part when spliced, and this water overflows the discard plate and falls onto the water leakage prevention plate, and drips from the gable side edge to the inside of the room. For example, there was a case where water leaked to the inside of the Tsumaki wall mating unit.

In particular, when tiles or natural slate is used as a roofing material and these are roofed in a steel structure building, or in the case of a roof in a special environment where the connecting portion of the roofing material is submerged in a snowy area, etc. There was a problem that water leakage frequently occurred at the joint.

Therefore, a water stop plate is interposed between the lower part of the rain presser and the upper surface of the roof material so that water such as rainwater is introduced from the lower edge of the rain presser to the upper surface of the roof material on the indoor side of the rain presser. Even when the water enters, various water leak prevention measures such as preventing the water from entering the indoor side of the water stop plate have been taken, but the water leak could not be reliably prevented.

The present invention solves the above-mentioned problems, and even if water such as rainwater enters the indoor side of the rain presser, it is possible to reliably prevent the water from leaking to the indoor side of the end face wall fitting section. It is an object of the present invention to provide a roof using a roofing material such as a tile that easily leaks water, and a gabled wall fitting fitting suitable for an environment in which the connecting portion of the roofing material is flooded.

[0009]

According to the present invention, a water leakage prevention plate laid on a base member is arranged below a roofing material such as a metal plate, a tile, or a natural slate via a space for drainage. The end portion of the roof side of the water leakage prevention plate is extended to the inside of the side surface of the roof surface layer of the lower floor opposite to the side wall of the roof side facing the side wall of the roof side. , The inside rain presser is arranged on the indoor side of the rain presser in which the standing portion is raised above the extension edge, the upper edge is supported and fixed to the end face wall, and the lower edge is brought into contact with the upper surface of the roof material. The upper edge of the inner rain presser is supported and fixed to the end wall, and the lower edge of the inner rain presser is hung below the roof surface layer portion on the upper surface of the water leakage prevention plate.

[0010]

[Working] The roof gable face wall fitting portion according to the present invention has an inner rain presser provided on the indoor side of the rain presser, and the upper edge portion of the inner rain presser is supported and fixed to the gable face wall to provide an inner rain presser. Since the lower edge of the water drop hangs down from the upper surface of the water leakage prevention plate, even if there is water that has infiltrated into the inside because the waste plate overflowed and was stored due to poor construction, this water will flow along the outside surface of the inside rain presser. Pour it down on the water leakage prevention plate. Since the lower edge of the inner rain presser hangs down on the upper surface of the water leakage prevention plate, the water that has flowed down hardly flows on the upper surface of the water leakage prevention plate toward the end face side of this hanging portion.

Further, even if some of the water that has entered the indoor side of the rain presser enters the end face side of the water leakage prevention plate rather than the hanging part of the inner rain presser, this water will still flow to the water leakage prevention plate. It is blocked by the standing part and does not enter the inside of the water leakage prevention plate.

Then, the water that has entered the upper surface of the water leakage prevention plate flows down due to the gradient and is discharged from the eaves of the space for drainage to the outside of the roof.

EFFECTS OF THE INVENTION In the gabled wall fitting part storage according to the present invention, in the roof where the water leakage prevention plate is laid on the base member through the drainage space under the roof material, the inside of the rain presser is inside. Since the rain presser is provided, the upper edge portion of the inner rain presser is supported and fixed to the end wall, and the lower edge of the inner rain presser is hung on the upper surface of the water leakage prevention plate, the following effects can be obtained.

In other words, in the roof end wall fitting portion of the present invention, even if the waste plate overflows and is contained due to defective construction or the like, and there is infiltration water to the inside, this water is the outside surface of the inside rain presser. Along the water leakage prevention plate.
Since the lower edge of the inner rain presser hangs down on the upper surface of the water leakage prevention plate, the water that has flowed down hardly flows on the upper surface of the water leakage prevention plate toward the end face side of this hanging portion.

Even if some of the water that has entered the indoor side of the rain presser enters the end face side of the water leakage prevention plate rather than the hanging part of the inner rain presser, this water will still leak to the water leakage prevention plate. It is blocked by the standing part and does not enter the inside of the water leakage prevention plate.

Then, the water that has entered the upper surface of the water leakage prevention plate flows down due to the gradient and is discharged from the eaves of the space for drainage to the outside of the roof.

Therefore, even if water such as rainwater enters the indoor side of the rain presser, it is possible to reliably prevent the water from leaking to the indoor side of the end face wall fitting portion.
