The fixing piece 4 and the side fixing piece 10 are parts for fixing the draining member A to the batten 2.
[0010]
The waterproof piece 7, the protruding piece 8, and the waterproof piece 9 are rainwater intrusion prevention walls formed so that rainwater or the like that has fallen on the draining piece 3 is blown back by a wind or the like and does not enter the back of the cabin.
[0011]
The ridge ventilation cover member D, as shown in FIG. 6 (c) ~ (d) , is made of a ridge ventilation cover B and the air passage forming member C.
[0012]
As shown in FIGS. 6A to 6B and FIGS. 7A and 7B, the building ventilation cover B has a cover surface 11 corresponding to the building and a fixed surface in which both ends of the cover surface 11 are suspended downward. 12, a draining surface 13 with the tip of the fixing surface 12 protruding outward, a tongue piece 14 with the tip of the draining surface 13 bent inward, a plurality of vent holes 15 formed in the cover surface 11, and a fixing It is formed from a plurality of ventilation / flowing water holes 16 formed on the surface 12.
[0013]
The fixing surface 12 is a part for fixing the ridge ventilation cover member D to the batten 2 and is a part for preventing the draining member A from being exposed to the outside.
[0014]
The ventilation hole 15 is a ventilation port formed to discharge the contaminated air W in the house, moist air W, excessively air-conditioned air W, and the like to the outside.
[0015]
The ventilation / flow hole 16 releases contaminated air W in the house, moist air W, excessively air-heated air W, etc. to the outside, condensed water generated inside, rain water entering the inside, etc. Is formed in order to release to the outside.
[0016]
As a material of the draining member A, the building ventilation cover B, and the building cover material K, a metal thin plate material such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, galvalume steel plate, enamel steel plate, clad steel plate, Roll forming of laminated steel plates (PVC steel plates, etc.), sandwich steel plates (damping steel plates, etc.), synthetic resin plate materials such as vinyl chloride resin and polycarbonate resin (including color plates coated with various colors). These are molded into various shapes by press molding, extrusion molding or the like.
[0017]
The heat insulating material B1 is formed on the back surface of the building ventilation cover B, particularly in the central portion, and prevents condensation caused by the temperature difference between the indoor temperature and the outside air temperature from being formed on the back surface of the metal building ventilation cover B. To do.
[0018]
The material of the heat insulating material B1 is synthetic resin foam, plastic, wood, inorganic material (calcium silicate board, calcium carbonate board, gypsum board, perlite cement board, rock wool board, slate board, ALC board, PC board, etc. Inorganic lightweight bodies, inorganic lightweight foams, etc., or composite plates thereof), metal plates, and the like.
[0019]
The synthetic resin foam is made of a synthetic resin foam such as polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam and the like. In addition, lightweight aggregates (perlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.), fibrous materials (glass wool, rock wool, carbon fiber, graphite, etc.) ) Can be mixed to improve fire resistance and fire resistance.
[0020]
The air passage forming material C is as shown in FIGS. More specifically, FIG. 8 (a) is an enlarged bottom view of FIG. 8 (b), FIG. 8 (b) is a front view, FIG. 8 (c) is a right side view of FIG. 8 (b), and FIG. FIG. 8B is a left side view of FIG. 8B, and FIG. 8E is a cross-sectional view taken along the line AA of FIG. 8B.
[0021]
The airflow path forming material C has a rising surface 17, an abutment surface 18 projecting the upper end of the rising surface 17 toward the ridge side and a lower end projecting toward the eave side, and the tip of the abutment surface 18 bent in the vertical direction . A support surface 20 that has a substantially horizontal “self” shape (or its reversal) from the side surface 19, the tip of the side surface 19 projects inward, a rising surface 17, and a plurality of ventilation paths 21 formed on the side surface 19; The air passage 22 and the air passage 23 are formed.
[0022]
The plurality of air passages 21, 22, and 23 formed in the air passage forming material C communicate the space γ behind the cabin with the space outside the house and form a space γ through which the air W flows. Needless to say, the air passage 21 also functions as a discharge hole for discharging condensed water, rainwater that has entered, etc. to the outside.
[0023]
The material of the air passage forming material C is a metal thin plate material such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, galbarium steel plate, enamel steel plate, clad steel plate, laminated steel plate (vinyl chloride steel plate, etc.), One type of sandwich steel plate (damping steel plate, etc.), synthetic resin plate material, such as vinyl chloride resin, polycarbonate resin, etc. (including color plates coated with various colors of course) are formed by roll molding, press molding, extrusion molding, etc. Molded into various shapes.
[0024]
9A to 9G show examples of the roof material R. FIG.
[0025]
In addition, in the figure, although the structure directly formed in the existing roof P is shown, it can form after removing the roofing material R, or it can form as a ridge structure of the roof of a newly built house. In this case, the existing roof P portion of the drawing serves as a base material such as a field board.
[0026]
Further, air W flows as shown by dotted arrows in FIGS. 2A to 2C, and a roof material R made of a metal-molded tile roof (shown in FIG. 9A) as shown in the figure. When used, and when the back surface of the roofing material R is formed in a structure in which the air W flows from the eaves toward the ridge, by controlling the temperature rise on the back surface of the roofing material R by the flow of the air W, the summer It also has a function to reduce the temperature rise in the cabin space and contribute to the improvement of comfort. In addition, FIG.2 (c) is a structure where the existing roof P of the ridge part is not removed but the space with a hut back is closed. Of course, when the roof material R having a structure in which the air W does not flow on the back surface of the roof material R is used, the unclean air W in the house is discharged from the back of the hut.
[0027]
Further, a ventilation fan may be formed in the building ventilation device forming part, and the flow of air W may be forcibly formed by turning it on and off.
