Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a roof of a building.

(Prior Art) Conventionally, a roof in which a support material is sandwiched between an existing roof and a new roof and an air layer is provided at the same roof is disclosed in Japanese Patent Laid-Open No. 57-140466, etc. Roofs in which a support material is sandwiched between and are provided with an air layer at the same portion are known from, for example, Japanese Utility Model Laid-Open No. 3-152422.

(Problems to be Solved by the Invention) However, the above-mentioned publicly known one has only an air layer between the new roof galvanized iron and the existing roof galvanized iron or the ground plate, and the air is stagnant. There was not much effect in melting the snow on top, preventing ice from adhering to the roof surface, and preventing the formation of dew on the attic. Therefore, an object of the present invention is to provide a roof having a novel structure capable of enhancing the effect of snow melting, the effect of preventing ice on the roof surface, the effect of preventing dew condensation on the attic, and the like.

(Means for Solving Problems) In order to achieve the above object, the roof of the present invention has an existing roof galvanized iron 1 and a new roof galvanized iron 3 when the new roof galvanized iron 3 is roofed on the existing roof galvanized iron 1. By laying a plurality of supporting members 2 in parallel from the ridge toward the eaves, the existing roof galvanized iron 1 and the new roof galvanized iron 3 are separated from each other to form the gap as the ventilation passage 4 and the ventilation passage 4 At the eaves-side end of the roof roof tin 1 and the new roof galvan 3 is installed inside the waterproof plate 11 to the inside position of the ventilation passage 4 and the ventilation port 10 for communicating the outside, and also the building of the ventilation passage 4 A ventilation opening 10 'for communicating the ventilation passage 4 at the end on the side and the ventilation passage 9 provided so as to communicate with the outside inside the building galvanized iron 7 are respectively opened. .

Also, in order to achieve the above-mentioned object, the roof of the present invention is such that, when the new roof galvanized iron 3 is roofed on the baseboard 5, it is moved from the ridge to the eaves between the mainboard 5 and the new roof galvanized iron 3. By laying a plurality of supporting members 2 in parallel toward each other, the base plate 5
And the new roof galvanized iron sheet 3 are separated from each other to form the gap as the air passage 4, and the roof plate 5 is provided at the eave-side end of the air passage 4.
And a new roof galvanized iron plate 3 are provided with a ventilation port 10 inside the waterproof plate 11 that connects the ventilation passage 4 and the outside, and at the end of the ventilation passage 4 on the ridge side with the ventilation passage 4 and the ridge. Galvanized iron 7
It is also possible to adopt a configuration characterized in that each of the vent holes 10 'for communicating with the ventilation path 9 provided so as to communicate with the outside is opened inside.

(Embodiment) First, in a first embodiment shown in FIGS. 1 to 3, a large number of wooden support members 2 are arranged in parallel at a predetermined interval from a ridge to an eaves on an existing vertical roof roof roof tin 1. The new roof galvanized iron 3 is roofed on the support materials 2 by the thatching method, and the space between the existing roof galvanized iron 1 and the new roof galvanized iron 3 is equal to the thickness of the support material 2. A gap is provided, and the gap is formed as a ventilation path 4, and ventilation is provided at a position inside the waterproof plate 11 that is installed so as to straddle the existing roof galvanized iron 1 and the new roof galvanized iron 3 at the eave-side end of the ventilation channel 4. A ventilation port 10 for communicating the passage 4 with the outside is opened, and the ventilation passage 4 and the outside are also connected to the ridge side end of the ventilation passage 4 through a ventilation passage 9 provided inside the wing galvanized iron 7. Vent holes 10 'for communication are provided respectively.

Next, the second embodiment shown in FIG. 4 is the base plate 5 of a new house.
A large number of wooden support members 2 are arranged side by side in parallel at a predetermined interval from the ridge toward the eaves and fixed, and a new roof galvanized iron 3 is roofed on these support members 2 by the lateral roofing method. A gap of about the thickness of the support member 2 is provided between the base plate 5 and the new roof galvanized plate 3 and the gap is formed as a ventilation passage 4, and the roof plate 5 is formed at the end of the ventilation passage 4 on the eaves side. And new roof galvanized iron 3
At the inner position of the waterproof plate 11 which is attached so as to straddle between the air passage 4 and the outside, a ventilation port 10 is opened, and at the same time, at the ridge-side end of the air passage 4 and inside the wing galvanized sheet 7. Vent holes 10 'for communicating the vent passage 4 with the outside through the provided vent passage 9 are provided respectively.

In the figure, 8 is a lantern hanging wire, 12 is a roofing material,
13 is a rafter, 14 is a purlin, and 15 is a goby joint.

In the above embodiment, the new roof galvanized iron 3 is roofed by the horizontal roofing method, but of course, it may be roofed by the vertical roofing method. Also,
It is also possible to use a material other than wood for the support material 2.

(Operation and Effect of the Invention) Since the present invention is as described above, unlike the known example, outside air is positively introduced between the new roof galvanized iron 3 and the existing roof galvanized iron 1 or the ground plate 5. Therefore, for example, in winter when the outside temperature is high during the daytime, the new roof galvanized iron is warmed from the inside by the outside air flowing through the ventilation passage to efficiently melt the snow and ice existing on the new roof galvanized iron. In addition to this, it is possible to effectively prevent the formation of dew condensation on the lower surface of the new roof galvanized iron. In addition to this, the air flowing through the air passage 4 also has the effect of alleviating the heat of the attic in the attic and cooling the room when the weather is extremely hot.
