Description

[Detailed description of the invention] This invention relates to a ridge structure with excellent waterproofness and ventilation.

Conventionally, this type of roof ridge structure has a ventilation passage formed in the ridge to ventilate the attic, but at the same time it is necessary to prevent rainwater from entering the interior through the opening of this ventilation passage. As a result, the ridge structure became complicated, and the flow of air through the ventilation passages was also complicated, resulting in problems such as not being able to ventilate smoothly.

The present invention has been made in view of the above points, and an object of the present invention is to provide a ridge structure that can waterproof the ridge part and allow smooth ventilation.

That is, the present invention arranges a ridge tile with an open bottom at the top of the ridge of the roof, forms ventilation notches at the lower ends of both sides of the ridge tile so that the interior of the ridge tile communicates with the inside and outside, and creates a ventilation gap between the inside of the ridge tile and the attic. The above objective has been achieved through a ridge structure formed with passageways.

The present invention will be explained in detail below with reference to Examples. As shown in Figure 1, there are multiple rafters 7 on the top surface of the ridgepole 6.
They are installed at regular intervals with a pitch of about 450 mm, and roofing boards 8 are installed on the top surface of the rafters 7 except for the area above the purlin 6. A roofing material 9 is placed on the upper surface of the shedding board 8, and a ventilation passage 4 is formed between the roofing material 9 and the ridgepole 6 on the ridge side. A flat plate 10 is mounted on the upper surface of the roofing material 9 on the ridge side.
A fixing portion 13 of a first draining iron plate 12 having a substantially C-shaped cross section is inserted and fixed between the roof material 9 and the flat plate 10. This draining iron plate 12 has a draining piece 14 erected above the ridge side front end of the flat plate 10, and a water returning piece 15 is bent outward from the tip of the draining piece 14. A support fitting 16 as shown in FIG. 5 is fixed to the top of the rafter 7 with nails 17 or the like. The support fitting 16 is provided with a fitting recess 22 in the lower part of a receiving fitting 18 which is open upward and has a U-shaped cross section, and also has a convex portion 24 of a fixing device 23 having a Y-shaped cross section in the fitting recess of the receiving fitting 18. A rafter 25 for fixing the ridge tile is fitted into this receiver 18 and fixed to the receiver 18 with nails 26 or the like.
The ridge tile 1 is formed of an inorganic or metal accessory or the like and has a substantially semicircular cross section with an open bottom surface, and a plurality of ventilation notches 2, 2 are formed at both ends of the ridge tile 1. The ridge tile 1 is placed on the top surface of the rafter 25 for fixing the ridge tile and nails 2 are attached.
7 etc., and both ends of it are fixed with flat plates 10 and 1.
It is placed on the top surface of 0. In addition, between the ridge tile 1 and the rafter 25 for fixing the ridge tile, as shown in FIG. A curved second draining iron plate 29 is sandwiched, and the water return plate 15 of the first draining iron plate 12 bends the draining piece 14, and a straightening piece 28a of the second draining iron plate 29 bends the draining piece 14. A ventilation gap 30 bent in a Z-shape is formed by placing the two curved draining legs 28 at an appropriate distance.

As shown by the arrows in FIG. 1, the air in the tunnel lining 3 can smoothly flow outdoors through the ventilation passage 4, the ventilation gap 30, and the ventilation notch 2, and can also be protected from rain. When it rains, rainwater that tries to enter the interior through the ventilation notch 2 is discharged to the outside by the slope of the flat plate 10, and the rainwater is completely prevented from entering by the draining iron plate 12 and the draining iron plate 29. It is something that In particular, when rain blows in with the wind, the draining legs 28 of the second draining iron plate 29 are pushed inward by the wind pressure and rotated, as shown in the imaginary line in FIG. The ventilation gap 30 between the drainer piece 14 and the drainer leg piece 28 is closed, and even rain falling on the side does not enter the interior. Since this draining iron plate 29 is firmly fixed between the tub tile 1 and the ridge tile fixing rafter 25, it will not shift due to vibrations caused by wind pressure or the like.

As mentioned above, this invention arranges a ridge tile with an opening on the bottom at the top of the ridge of the roof, and forms ventilation notches at the lower ends of both ends of the ridge tile that allow the inside of the ridge tile to communicate inside and outside, and between the inside of the ridge tile and the attic. In a ridge structure in which a ventilation passage is formed in the ridge structure, a water strip is erected from the ridge side surface end of a fixed part attached to the upper surface of the roof material on the ridge side, and a water return strip is erected from the tip of the water strip to the outside. A first draining iron plate that is bent and has a substantially C-shaped cross section, and a rectifying piece extending inward from the tip of a draining leg piece that hangs down via a hinge from both ends of a central piece attached to the inner surface of the top of the ridge tile. A Z-shape is formed by placing a second draining iron plate with a bent water draining plate, and a draining piece with a bent water returning piece with an appropriate distance between both draining leg pieces with a bent rectifying piece. This is a ventilation gap that is curved in the shape of a shape, and allows the air in the attic to be released outdoors through the ventilation passage and ventilation notch, allowing for smooth ventilation of the attic, as well as the ventilation gap in the roof ridge. This has the effect of preventing rainwater from entering the attic by blocking the rainwater that falls on the roof with the ridge tiles.In addition, the rectifying piece of the second draining iron plate connects both draining leg pieces, each of which is bent, through the hinge part. hanging down,
A first draining iron plate is placed between both draining leg pieces at an appropriate interval to form a ventilation gap bent in a Z-shape. The direction of the wind flowing in from the outside through the passage formed between them is reversed by the Z-shaped ventilation passage, so even if there is wind, it can effectively prevent rainwater from entering the interior. In the event of even stronger wind and rain, the draining legs of the second draining iron plate are pushed inward by the wind pressure and rotate to close the ventilation gap between the draining legs. This has the effect of more reliably preventing rainwater from entering due to sideways rain.
