Utility model registration No. 3012289 Patent registration 3358474

  However, when a dry wall material using a synthetic resin foam as a core material is used, rainwater that has entered the drainer jumps up and comes into contact with the synthetic resin foam at the end of the dry wall material end, so that the moisture is in the synthetic resin. There was a risk of permeating into the foam and causing adverse effects such as rusting of the iron plate of the surface material, corrosion of the synthetic resin foam, and prevention of deterioration of heat insulation due to wet ragging.

In order to eliminate such drawbacks, the present invention eliminates such a vertical flat fixed portion, an inclined surface that is slanted with the upper end of the fixed portion inclined downward, and a lower end of the inclined surface that is inclined outward and upward. An elongated decorative surface formed from a protruding inclined decorative surface and a decorative surface protruding upward at the tip of the inclined decorative surface, and a flowing water / vent hole formed at regular intervals at the lower end of the inclined surface and the inclined decorative surface The parting edge is fixed horizontally and continuously to the base part of the wall base, and the dry wall material is formed by inserting a bottom end of the dry type wall material into the parting edge space, and the dry type wall material is made of synthetic resin foam. A vertical dry wall material provided with a ventilation groove on the back side is used, and the working width of the dry wall material is the lower end structure of the wall formed corresponding to the pitch of the wall base.

According to the wall lower end structure according to the present invention,
(1) Rainwater that has entered the interior of the running water / vent hole is quickly discharged to the outside.
(2) Since the inclined surface and the inclined decorative surface are formed, the rainwater that has entered the interior flows down quickly, the rainwater does not come into contact with the mouth of the drywall material, and the core of the drywall material is a synthetic resin foam. In this case, it is effective for preventing corrosion of the synthetic resin foam, preventing the heat insulation from being lowered due to wetting, and preventing the corrosion of the wall base and the strength of the dry wall material.
(3) It has an exhaust function for releasing moisture, contaminated air, waste heat, etc. in the wall to the outside.
(4) The air passage functions as an air layer and can make use of heat insulation.
(5) No condensation occurs in the air passage (wall).
(6) Since condensation does not occur, it is difficult for the enclosure to decay.
(7) The dry wall material in which the air passage (air layer) is formed functions as a heat insulating material.
(8) Since the dry wall material functions as a heat insulating material, the cooling efficiency in summer and the heating efficiency in winter can be improved.
(9) Due to the heat insulation of the dry wall material, the temperature of the back surface and the wall of the dry wall material is kept high, and the occurrence of internal condensation is further suppressed.
(10) Since a dry wall material formed with a working width corresponding to the pitch of the frame of the wall base is used, it is not necessary to form a horizontal trunk edge on the wall base, reducing the cost and improving the workability.
(11) Since the core material of the dry wall material is formed of a synthetic resin foam, it accumulates daytime heat and dissipates heat at night as when a ceramic-type outer wall material is used as a conventional outer wall material. In summer, air-conditioner cooling efficiency is improved, and in winter, heating efficiency is improved, saving energy and reducing costs.
There are features and effects.

  Hereinafter, an embodiment of the lower end structure of a wall according to the present invention will be described in detail with reference to the drawings. That is, FIG. 1, FIG. 2 (a), (b) is sectional drawing which shows one Example of the lower end part structure of the wall based on this invention, FIG. 3 (a)-(c) is the lower end of the wall based on this invention. It is sectional drawing which shows the parting edge A used for a partial structure, and a partially cutaway perspective view. 4A and 4B are cross-sectional views of the dry wall material B, and FIG.

  The parting edge A includes a vertical flat fixed portion 1, an inclined surface 2 that hangs downward by inclining the upper end of the fixed portion 1, a bottom surface 3 that protrudes outward from the lower end of the inclined surface 2, and a bottom surface 3. An inclined decorative surface 4 that protrudes outwardly and upwardly, a decorative surface 5 that protrudes upward from the distal end of the inclined decorative surface 4, and a tongue piece 6 in which the distal end of the decorative surface 5 is folded inward. In the figure, a space 8 is formed from running water / ventilation holes 7 formed on the bottom surface 3 at regular intervals, the inclined surface 2, the bottom surface 3, the inclined decorative surface 4 and the decorative surface 5.

  The fixing part 1 is a part for fixing the parting edge A to the wall base α by a fixing tool β.

The inclined surface 2 forms a space 8 at the parting edge A, and as shown in FIG. 6, the space 8 is formed between the end B1 of the dry wall material B and the parting edge A as shown in FIG. When rainwater enters, the rainwater does not come into contact with the end B1 of the dry wall material B, and the end B1 is prevented from getting wet.

  The bottom surface 3 is formed at the lower end portion of the inclined surface 2 and the inclined decorative surface 4 and functions mainly as a place where the running water / ventilation hole 7 is formed. It is a part formed for discharging.

  The inclined decorative surface 4 is an inclined portion that is formed to smoothly drain rainwater that has entered inside to the outside through the flowing water / ventilation hole 7, and the recessed portion 14 of the dry wall material B is suspended by being inclined. This prevents rainwater from splashing and getting the core material 10 of the lip B1 wet. For this reason, it is possible to prevent corrosion due to water absorption by the core material 10, deterioration of heat insulation due to wet ragging, corrosion of the wall base α, and reduction in strength of the dry wall material B.

  The decorative surface 5 is a portion that covers the bottom B1 portion of the lower end portion of the dry wall material B and prevents the lower end portion of the dry wall material B from being exposed to the outside.

  The tongue piece 6 is a portion formed so as not to be injured by the end portion of the parting edge A formed of a metal plate material.

  The running water / ventilation holes 7 are formed on the bottom surface 3 at a constant pitch, and discharge rainwater that has entered from between the dry wall material B and the decorative surface 5 of the parting edge A to the outside. Moreover, the formation pitch of the flowing water / ventilation holes 7 is about 30 to 300 mm.

  The materials include thin metal plates such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plates, galvalume steel plates, enameled steel plates, clad steel plates, laminated steel plates (PVC steel plates, etc.), sandwich steel plates (damping steel plates, etc.) ), Vinyl chloride resin, polycarbonate resin, etc. (of course, including color plates coated with various colors) are molded into various shapes by extrusion molding, roll molding, press molding, or the like.

As shown in FIG. 4, the dry wall material B forms a core material 10 between the surface material 9 and the back surface material 11, forms a convex portion 13 and a concave portion 14 on the decorative surface 12 of the surface material 9, and females at the upper and lower ends. A mold connecting portion 15 and a male connecting portion 16, a ventilation groove 17 is formed on the back surface, and a packing 18 is formed in the male connecting portion 16. The dry wall material B is connected by fitting the male connecting portion 16 .

  Thus, by forming the working width W of the dry wall material B corresponding to the formation pitch P of the wall base α, the dry wall material B can be formed without forming a fixed base such as a trunk edge on the wall base α. Can be constructed vertically, and the air passage T 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 wall base α can be specified by the fixing position of the board, so there is no problem in the construction of the dry wall material B. is there.

  The surface material 9 and the back material 11 are metal thin plates, for example, 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.), sandwich steel plate (control) Corrugated steel sheets, etc.), vinyl chloride resin, polycarbonate resin, etc. (including color plates coated with various colors, of course) formed into various shapes by roll molding, press molding, extrusion molding, etc., or inorganic materials Are formed into various arbitrary shapes by extrusion molding, press molding, autoclave cultivating form, extrusion-drying-firing, and the like.

  The core material 10 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. An agent and a foaming agent are mixed, discharged onto the back surface side of the surface material 9 or the back material 11, and heated to react, foam and cure.

  The core material 10 made of a synthetic resin foam does not accumulate heat during the day and dissipate heat at night as in the case of using a ceramic outer wall material as the conventional dry wall material B in summer. In summer, air-conditioner cooling efficiency is improved, and in winter, heating efficiency is improved, saving energy and reducing costs. This is because the ceramic-based outer wall material has the property of storing heat and gradually dissipating heat because the specific gravity is large, whereas the wall according to the present invention using the core material 10 made of synthetic resin foam is used. Since the dry-type wall material B used in the lower end structure does not store heat, it does not emit heat at night, forms a comfortable living space, and saves energy and reduces costs.

As shown in FIGS. 2B and 4B, when the formation pitch of the wall base α is P and the working width of the dry wall material B is W, W = P or W = n × P (n is positive) The working width W of the dry wall material B is formed corresponding to the formation pitch P of the wall base α3. 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.

  The ventilation groove 17 is formed by a portion where the back surface of the dry-type wall material B is recessed to form a recess, and as shown by the dotted arrow, fresh external air that has entered through the flowing water / ventilation hole 7 It is a space for exhausting indoor humidity, polluted air, waste heat, etc. to the outdoors. The dimension H is about H = 7 mm to 12 mm. Of course, at the upper end portion of the ventilation path T formed by the ventilation groove 17, a perforated hole formed on the eaves, or an eaves-perforated plate formed on the eaves, moisture, contaminated air passing through the ventilation path T, Waste heat is discharged outdoors.

  Next, the construction method of the lower end structure of the wall according to the present invention will be briefly described. First, the parting edge A as shown in FIGS. 3 (a) to 3 (c) is driven by the fixture β as shown in FIG. 1, and is continuous with the wall base α on the drainage C of the foundation γ part. Fix several in a shape. Next, dry-type wall materials B as shown in FIG. 4A are sequentially connected, and the bottom end B1 is inserted into the space 8 and installed vertically.
