Abstract

PROBLEM TO BE SOLVED: To simplify execution and reduce cost by forming a lower drip sheet metal installed in a ventilation opening of a ridge and an upper ridge sheet metal covering the outside of the lower drip sheet metal by a sheet metal work. SOLUTION: Lower drip sheet metal 2, 2 perpendicularly rising from the upper ends of bottom plates parallel to a roof inclination and having a section in which the terminal ends are bent downward to form an inverted U-shape are prepared. And also an upper ridge sheet metal 1 having a section in which it is hung down from both ends of a chevron shape and both ends are bent inward to have an upward U-shaped form, is prepared. A pair of lower drip sheet metals 2 are installed at the both outsides of the ventilation opening 10 opened upward installed in the ridge. An upper ridge sheet metal 1 is installed upward from the outside of the lower drip sheet metal 2 so as to form a ventilation passage. In this way, the ventilation ridge can be constructed while using respective separate parts fabricated from sheet metals. Since a large-scaled mechanical device is not used, the cost can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation building to be installed in a ridge portion of a roof of a house for exhausting moisture and hot air from an attic in a wooden house construction.

[0002]

2. Description of the Related Art Ventilation buildings up to now include those manufactured by assembling aluminum extrusions and those manufactured by sheet metal, but have a complicated structure and a large number of parts.

[0003]

As in the prior art, an aluminum extruding machine is a large-sized device, has a large depreciation cost, and cannot be produced unless mass production is performed. Also, those made of sheet metal have a complicated structure and require a manufacturing fee.
It is expensive for the above reasons.

[0004]

According to the present invention, as shown in FIG. 1, a separate body separated into a drain plate 2 and an upper plate 1 is shown in FIG.
It is very simple because it bends and drills mounting holes like this, and the processing machine can be easily manufactured if there is a simple sheet metal cutting machine and bending machine, so the price can be reduced.

[0005]

Embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, after the roof board 5 is stretched on the roof, a ventilation opening 10 having a width of about 40 mm is opened at the top. Take the length as needed.

Next, the ventilation port side plate 3 is mounted along the opening with a tree or a substitute material, and a ridge lower tree 6 is mounted thereon at a pitch of about 600 mm.

[0007] After laying a roofing material on the field board, the roofing tiles 4 are stopped with nails and the roof tiles 7 are laid up to the ventilation side plate 3.

Next, a sewage sheet metal 2 having a cross section shown in FIG.
On both sides of the ventilation hole side plate 3 with nails or screws. Next, the upper building sheet metal 1 is attached to the lower building 6 with nails or screws. After the rain before and after, it is completed.

As the material of the draining sheet metal 2 and the draining sheet metal, rustproof steel plate, stainless steel, aluminum or the like can be used.

[0010] The upper ridge sheet metal may have an arc shape at the top instead of a corner as shown in FIG.

As shown in FIG. 7, a net 9 for preventing infiltration of rainwater and insects may be provided between the upper sheet metal and the sewage sheet metal.

[0012]

【The invention's effect】

Since the present invention is configured as described above, the following effects can be obtained.

As described in Means for Solving the Problems, each of the separate parts can be manufactured at a low cost because it only processes a sheet metal and does not use a large-sized mechanical device.

[0015] By providing a net for preventing rainwater and insects, the infiltration of rainwater and insects can be further enhanced.

The mounting method can be simplified as in the embodiment, and the mounting cost is low.

Claims (3)

[Claims] 1. A ventilation building in which a pair of drainage sheet metal is installed on both outer sides of a ventilation opening of an upper opening in a ridge portion, and is installed from above the outside so as to cover the drainage sheet metal so that a ventilation path can be formed. The drainage sheet metal has a cross section which rises vertically from the upper end of the bottom plate parallel to the roof slope and has its end bent outward in a downward U-shape, and the upper ridge sheet metal hangs from both ends of the chevron. The end is bent upward in a U-shape to form a cross section. 2. The ventilation building according to claim 1, wherein the top of the upper ridge sheet metal has an arc shape. 3. The ventilation building according to claim 1, wherein a net for preventing infiltration of rainwater and insects is provided on the inner surface of the ventilation path between the upper and lower ridge sheet metals.
