JPH09242200A - Throating device of bent part in mansard roof - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain an excellent waterproof function and a sharp external appearance, by fitting a dog leg-shaped throating part by a chevron-shaped outside throating of the lower part, a folded part of the upper part, and a folded-back part so as to position astride on the bent part of the mansard roof. SOLUTION: An outside throating 15 with a chevron-shaped section is connected at the lower side of the bent part of the dog leg-shaped body 14 and the upper side is bent 10 upward to form a hook-shape and the upper end is upward diagonally folded back 11 and then bent rearward to form a throating material 3. The throating materials 3 are put on the roofing material 9 at both sides of the bent part of the mansard roof so as to position astride on the upper and lower sawn boards 8, 8 and fixed with nails 13. And further, asphalt roofing materials 13 are laid on the upper body 14 than the bent part and a roofing material 20 is laid. And a backing material 16 is inserted in the inside of the chevron-shaped part of the outside throating 15 and fixed to the sawn boards 8 with nails 17 from the outside. The upper end of a roofing plate 18 is inserted between the outside throating 15 and the body 14. And the lower end of the outside throating 15 is folded back inward at the upper face of the roofing plate 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a draining device for a bent waist portion of a mansard roof.

[0002]

2. Description of the Related Art In a mansard roof, it is not possible to continuously provide a roofing material laid on a gentle slope portion on the upper side and a roofing material laid on a steep slope portion on the lower side. In this case, a waterproof sheet such as asphalt roofing is provided on the lower side of the roofing material, but there is a drawback that a sufficient waterproof structure cannot be obtained by this alone.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a draining device having a sufficient waterproof effect and an excellent appearance in such a bent portion of a mansard roof.

[0004]

In order to solve the above-mentioned problems, according to the present invention, in a mansard roof in which the middle part in the direction of inclination of a sloping roof is bent into a waist fold, the steepest roof below the waist fold is It is characterized in that a draining member is provided so as to cover the upper end of the upper roofing material and to extend over the steep slope side and the gentle slope side.

Further, the above-mentioned draining member can be formed by bending a portion exposed from the roof member into a mountain-shaped cross-section so that a sharp appearance in which a ridgeline of a waist bending portion passes in a horizontal direction can be revealed.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a mansard roof of a house, in which an intermediate portion of the roof surface in the eaves direction is bent like a waist, and a gently sloped roof surface on the ridge side is bent through the waist.
It is divided into (1) and the steep roof surface (2) on the eaves side. And the draining material (3) of the present invention along the waist bend,
It is mounted in columns.

FIG. 2 shows a cross section of the roof portion at the bent portion of the waist, and the upper and lower roof frames (4) and (5) sandwiching the bent portion of the waist.
A wooden purlin (7) is fixed to the upper surface of the building through metal fittings (6) and (6), and field boards (8) and (8) are attached to the purlin (7). (9) shows the asphalt roofing laid across the upper surfaces of the field boards (8) and (8).

[0008] And this asphalt roofing
Above and below (9), the upper and lower floor boards (8) which also sandwich the waist break.
The doglegged body (14) of the draining member (3) is attached so as to straddle between (8). The upper side of the waist bending portion of the main body (14) is once bent upward (10) and then extends upward, and further the upper end thereof is obliquely folded back to the upper surface side (11) and then upward. It is bent and nailed (12) at its tip. In this upper portion, asphalt roofing (13) is further laid from above the draining material body (14) as shown in FIG.

On the other hand, an outer drainer (15) having a chevron-shaped cross section is continuously provided on the upper surface of the draining member body (14) below the waist-folding portion. And
A base material (16) made of square timber is inserted inside the mountain portion of the outer drainer (15), and is fixed to the base plate (8) by nails (17) driven from the outside.

On the lower side of the base material (16), the upper end of the plate-shaped roofing material (18) is inserted from the lower side between the outer drainer (15) and the drainer body (14). Also draining outside (15)
The lower end of the fold back inward on the upper surface of the roofing material (18) (2
1) Has been done. On the other hand, a roofing material (20) is also installed on the upper surface of the asphalt roofing (13) above the waist bending part. (22) of FIG. 3 is a drainer attached to the end of the roof on the gable side.

[0011]

As described above, according to the present invention, since the upper end of the roofing material on the lower side of the waist bending portion of the mansard roof is covered with the draining material and is further provided over the waist bending portion, It has the effect of improving the waterproof property. In addition, by providing the draining material along the bent portion in this manner, the appearance of the roof can be made sharp.
