た。However, in the above-mentioned conventional ventilation structure, since the emphasis is placed on the rainfall, which is the primary function of the roof, the air flow path formed becomes complicated, and It has a structure in which a plurality of plate members are complicatedly bent and combined. Therefore, there was a problem that the manufacturability and workability were poor and the product was expensive.

However, in this case, many of the roof-related accidents are occupied by splashing or turning over of the ridge and subsequent leakage. The cause is that the ridge is at the top of the building and it is the last storage, so fixing tools such as nails penetrate the wrapper and fix it on the groundwork and waterproof around the head of the fixing tool. Conceivable. That is, in the short to medium term, waterproofing treatment is effective, so that no intrusion water occurs, but in the long term, dew condensation water generated in the fastener and the area around the head of the fastener due to the thermal expansion and contraction of the ridge wrapper intrude water. It is considered that this causes accidents such as splashing, turning over, and water leakage due to the occurrence of corrosion or the corrosion of the wooden substrate.

Next, the ventilation member 1 is placed on the fixing portion 52 of the support frame 5 so that the lower surfaces of the side portions 12, 12 are grounded.
In a state in which it is disposed so as to cover
2, a fastener such as a drill screw is driven into the mounting portion 53 of the support frame 5 (and the protruding receiving portion 2 d of the side surface portion 12 of the ventilation member 1 inside). Since the fixed portion 52 of the support frame 5 is formed to have a width substantially equal to the width of the lower end of the side surface portion 12 of the ventilation member 1, positioning can be easily performed simply by fitting the fixing portion 52 from above. Other configurations in the ventilation structure are not particularly limited. For example, any exterior material 6 and base 7 may be employed. For example, the exterior material 6 is not particularly limited to a material, but a surface decorative steel plate, a laminated steel plate, a plated steel plate, a stainless steel plate, an aluminum alloy plate, a titanium alloy plate,
A known metal material such as a copper plate, a brass plate, or a lead plate is formed into a predetermined shape by roll forming or other means. Note that the exterior base material may be made of a composite material instead of a single material. The shape, connection, and fixing method of the exterior material 6 are not particularly limited, and may be any of conventionally known fitting, overlapping, and engaging types. For example, the base 7 is generally made of a steel frame such as a beam, a purlin, and a rim, but is not limited thereto. For example, a configuration in which a base material such as a wool cement board, a wood chip cement board, a lightweight cellular concrete board or the like is laid on the steel frame body, or a configuration in which a steel frame or wood hut is laid on a concrete frame, The support frame 5 may be directly attached to the concrete surface whose foundation has been adjusted. As described above, the foundation 7 refers to all the building frames to which the support frame 5 can be attached by fixing means such as nails, screws, anchors, welding, etc., and wood wool cement to be laid on the frame by heat insulation or other as necessary. It includes boards such as boards.

きる。Further, in the ventilation structure of the present invention, the fixing member is not fixed to the substrate by penetrating the surface plate as in the prior art, but the surface plate 4 is indirectly connected to the substrate 7 through the support frame 5.
Therefore, even if the periphery of the head of some of the fixing tools to be attached to the support frame 5 is deformed, water does not enter. Particularly, in the ventilation structure of the illustrated embodiment, since a polystyrene foam, which is an integrally molded product of a non-permeable foam resin material, is used as the ventilation member 1, a plurality of plate-shaped members are complicatedly bent and combined. The production cost is lower than in comparison. In addition, since there is no corrosion, the weight is small and the number of members is small, workability is also improved. Therefore, with the ventilation structure of the present invention, it is possible to prevent a decrease in strength due to aging corrosion of a wooden base, a subsequent scattering accident, a water leakage accident, and the like, as in the past, and a ventilation ridge structure excellent in raining over the years. Can be provided.

ことが望ましい。Further, since the projecting receiving portion 2 in the illustrated embodiment is arranged such that the air flow path 31 connecting the intake / exhaust port 421 of the surface plate 4 and the communication port 32 has a zigzag shape, the provisional receiving section 2 is temporarily provided. Even if rainwater enters through the intake / exhaust port 421 together with the strong wind, the entered rainwater collides with the protruding receiving portion 2 and further infiltration is prevented. As described above, it is desirable that the air flow path 31 be non-linear so that the projecting receiving portion 2 has a water return function.

By mounting the disposing slit 121 formed on the back side of the eaves side, that is, on the lower surface of the side surface portion, to the position regulating portion 55, positioning at the time of construction is facilitated. Although the support frame 5 in FIG. 5A is described as a piece material, the support frame 5 may be a through material as long as a communication port through which air flows in the contact portion 51 is opened. Further, in the support frame 5 of FIGS. 7A and 7B, the mounting portion 53 may also serve as the position regulating portion 55.

A reinforcing rib 111 may be provided on the back surface side of the inclined surface portion 11 to obtain high support strength and prevent breakage of the member before construction. Further, as shown in FIG. The shape of the contact portion 51 of the support frame 5 may be changed so as to closely contact the back surface shape. In the illustrated embodiment, the inclined portion 11
The shape of the protruding receiving portion 2b (eave-side corner) having a rhombic cross section formed on the front surface side is changed, and the end surface thereof is inclined.
