  The present invention relates to a ventilation wall structure having a heat insulation function, a heat insulation function, a moisture exhaust function, an exhaust function, a dew condensation prevention function, a waterproof function, and the like.

  When the wall is hermetically sealed, there is no place for water vapor to escape, and condensation occurs on the back of the outer wall material or on the wall if the outside air temperature is low. Therefore, a method of providing an air layer with a thickness of about 20 mm between the outer wall material and the housing in order to discharge water vapor in the wall to the outside air to prevent internal dew condensation and to discharge moisture that has soaked into the base and pillars to the outside air. A so-called aeration method has been developed. Originally, the ventilation method is a method for preventing dew condensation in the wall. (For example, refer to Patent Documents 1 to 6).

  However, Patent Documents 1 to 6 discharge moisture, but the ceramic industry outer wall material has a large specific gravity, so it accumulates heat and has a property of gradually releasing heat, releasing heat at night, and comfortable It was not possible to form a comfortable living space, and energy loss and cost were increased. Moreover, in order to prevent the leakage of ceramic outer wall materials, a ventilation method is often adopted, and many people are now considering it as a method for finishing rain.

  In order to solve such drawbacks, the present invention provides a vertical plane in a wall structure in which an air passage is formed between an outer wall material and a wall substrate by attaching a vertical outer wall material having a depression on the back side to the wall substrate.

There are features and effects.

  The ventilation wall structure according to the present invention will be described in detail below with reference to the drawings. FIG. 1A is a cross-sectional view showing a vent wall structure according to the present invention, and FIG. 1B is a cross-sectional view showing the air flow in the vent wall structure according to the present invention. 3 is a cross-sectional view showing a vent wall structure according to the present invention, and FIGS. 4A and 4B are explanatory views showing an example of an outer wall material A used in the vent wall structure according to the present invention. In the figure, α is a wall base, β is a fixture such as a nail, γ is an air passage, and γ1 is exhaust air. The exhaust air γ1 is moisture, polluted air, waste heat, etc. and should be exhausted outdoors.

As an example of the wall base α, the interior material 1, a moisture-proof layer 2 such as a polyethylene sheet (indicated by a one-dot chain line), a main body 3 such as a main pillar and a stud, and a heat insulating material 4 such as glass wool formed between the main bodies 3 are formed. Is. Note that the frame 3 includes a wooden shaft method, a wooden frame method (two-by-four method), a steel shaft method, and the like.

  5 is a wind-proof and moisture-permeable layer (indicated by a two-dot chain line), a moisture-permeable waterproof sheet (nonwoven fabric that passes only moisture without passing through wind and rain), or a moisture-permeable waterproof board (a highly moisture-permeable sizing board, sizing insulation) Board, etc.) and formed from a member having moisture permeability, windproof property, waterproof property, and the like.

  A is an outer wall material, which is a member having functions such as heat insulation, heat insulation, waterproofness, airtightness, weather resistance, etc. For example, a metal-based outer wall material as shown in FIG. An outer wall material or the like is used, and it also functions as the air passage forming member 6 that forms the air passage γ. 2 (a) and 4 (b), if the formation pitch of the casing 3 is P and the working width of the outer wall material A is W, W = P or W = n × P (n is a positive value) The working width W of the outer wall material A is formed corresponding to the formation pitch P of the housing 3. Specifically, the dimensions of W and P are 455 mm (1 scale 5 dimensions), 910 mm (3 scales), 500 mm, 1000 mm, and the like.

  Thus, by forming the working width W of the outer wall material A corresponding to the formation pitch P of the housing 3, the outer wall material A can be formed vertically without forming a time when a body edge or the like is fixed on the housing 3. Construction is possible, and the air passage γ is also continuously formed from the base toward the eaves. Of course, even when a heat insulating material such as a board is formed on the wall base α, the location of the housing 3 can be specified by the fixing position of the board, so that the construction of the outer wall material A is not hindered.

  More specifically, the outer wall material A is a vertical metal outer wall material or ceramics outer wall material formed integrally from a surface material B, a core material C and a back material D, and forms a male-female connection structure at the end. Long plate material (8, 9.5, 10, 12, 12, 2.5, 18, 24, 3 m, 3.8 m, 4 m, 6 m, etc.).

  The surface material B and the back material D of the outer wall material A made of a metal-based outer wall material are metal thin plates such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, galvalume steel plate, enamel steel plate, clad steel plate, laminated steel plate. (Vinyl steel plate, etc.), sandwich steel plate (damping steel plate, etc.), vinyl chloride resin, polycarbonate resin, etc. (of course, including color plates coated with various colors) by roll molding, press molding, extrusion molding, etc. These are molded into various shapes, or formed into various arbitrary shapes by extrusion molding, press molding, autoclave ripening form, etc. of inorganic materials.

  The core material C is made of, for example, a synthetic resin foam C1 such as polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, etc., and particularly when fire resistance is required. Is formed by mixing a stock solution of a resol type phenol, a curing agent, and a foaming agent, discharging the mixture onto the back surface side of the surface material B or the back material D, and heating, reacting, foaming, and curing.

Further, in the core material C, lightweight aggregates (perlite grains, glass beads, gypsum slag, talc stone, shirasu balloon, aluminum hydroxide, etc.), fibrous materials (glass wool, rock wool, carbon fiber, Graphite and the like) can be mixed to improve fire resistance and fire resistance.

  Synthetic resin foam C1 does not accumulate heat during the day and does not dissipate heat at night as in the case of using a ceramic outer wall material as the conventional outer wall material A in summer. In this way, the efficiency of cooling is improved, and the efficiency of heating is improved in winter, thereby saving energy and reducing costs. This is because the ceramic-type outer wall material has a property of storing heat and gradually releasing heat because the specific gravity of the ceramic-based outer wall material is large, whereas the ventilation wall according to the present invention using the synthetic resin foam C1 as the core material C Since the outer wall material A used in the structure does not store heat, it does not release heat at night, forms a comfortable living space, and saves energy and reduces costs.

  The air passage γ is formed by a portion in which the back surface of the outer wall material A is recessed to form a recess A1, and is a space for exhausting indoor moisture, contaminated air, waste heat, etc. to the outdoors. It is. The dimension H is about H = 7 mm to 12 mm.

  7 is an upper opening, 8 is a lower opening, communicates with the air passage γ formed by the outer wall material A, and is an outlet for exhausting exhaust air γ1 such as indoor humidity, contaminated air, waste heat, etc. to the outside, Or it is a part which functions as an entrance. Of course, in the figure, since the upper opening 7 is exposed inside the eaves, the exhaust air γ1 is sent from the eaves-perforated plate 10 formed in the eaves, or from the building ventilation port (not shown). As shown by the arrows in FIG.

Reference numeral 9 denotes a drainer, which is a member for accommodating the lower end portion of the outer wall material A.

  Reference numeral 10 denotes an eaves-perforated plate for discharging moisture, polluted air, waste heat, and the like that have passed through the air passage γ to the outside, and formed a ventilation portion 10a having a plurality of holes. Is.

Is. The parting edge S functions as a cover decorative material for the lower end lip of the outer wall material A and a ventilation path forming material for forming the ventilation path γ communicating with the base part, and the outer wall material having a cross-sectional shape in which the ventilation path γ is formed. The weak point A is weak against the negative pressure of the wind-resistant pressure, etc., is formed in order to improve the strength against the negative pressure at the wind-resistant pressure by forming the parting edge S.

  The fixing part 11 is a part for fixing the parting edge S to the wall base α with a fixing tool β.

The lower end surface 15 protrudes outward and inclining upward, so that rainwater that has entered the interior flows quickly into the water outlet 19.

  The vent hole 18 is formed mainly for taking fresh air into the back surface of the outer wall material A and discharging contaminated air discharged from the inside of the fuselage to the outside. The water outlet 19 is mainly for discharging rainwater that has entered from between the outer wall material A and the cover decorative surface 16 of the parting edge S to the outside.
