Description

TECHNICAL FIELD The present invention relates to a building mortar-coated outer wall ventilation layer forming member using a lath material, in particular, rib lath material, a manufacturing method thereof, and a building mortar-coated outer wall ventilation layer forming method.

  Conventionally, for example, a predetermined space is generally formed in a mortar-coated outer wall of a wooden house, for example. And when the air temperature in the outer wall space portion of the mortar coating is cooled by a temperature difference with the surrounding temperature or the like, and below the so-called dew point temperature, the water vapor in the wall condenses into water droplets, that is, It is said that there is a high possibility of causing condensation in the walls.

This dew condensation in the wall may cause mold, corrosion, rust, etc., and may have a great influence such as reducing the durability of the building or shortening the life of the building.
In order to improve such a state, in recent years, a so-called mortar-coated outer wall ventilation method has been developed as means for releasing moisture in the wall to the outside.

  In this mortar-coated outer wall ventilation method, moisture inside the building is covered with a material called a breathable waterproof sheet, and a layer through which the outside air flows is created between the mortar-coated outer wall material and moisture inside the wall is permeable to moisture. A method of discharging from the waterproof sheet to the outside through the ventilation layer is adopted.

Specifically, for example, after covering the wall with the moisture permeable waterproof sheet, a ventilation cylinder edge is provided, and a lath net is laid on the ventilation cylinder edge to finish the outer wall of the mortar.
Thereby, internal condensation can be decreased, and as a result, the effect that the durability of a building can be improved can be expected.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings.

  FIG. 1 is an explanatory view showing the structure of a mortar-coated outer wall ventilation layer forming member 1 according to the present invention.

  A mortar-coated outer wall air-permeable layer forming member 1 includes a plurality of horizontally extending groove ribs 2 provided at intervals, a lath material 3 having a mesh portion formed between the groove ribs 2, 2, and the lath A waterproof sheet 4 attached to one surface of the material 3 is provided.

Here, the type of the waterproof sheet 4 will be described. Mainly, polymic paper and tarpaulin paper are used. Polymic paper is obtained by sandwiching both sides of a polyethylene sheet with kraft paper, and tarpaulin paper is formed by sandwiching both sides of an asphalt waterproof layer with kraft paper.
Since there is no difference in both waterproof performances, both are generally used as lath waterproof paper.

  And in the longitudinal direction of the groove rib 2, the groove rib 2 is formed so as to be substantially perpendicular to the longitudinal direction of the groove rib 2 and project in a substantially mountain shape toward the adhered waterproof sheet 4 side. For example, a plurality of ventilator rim portions 5 that form concave grooves formed by bending so as to protrude in a substantially mountain shape toward the waterproof sheet 4 side are provided at intervals.

  That is, as shown in FIG. 2, the mortar-coated outer wall air-permeable layer forming member 1 is formed in a cross-sectional shape that is substantially uneven in the horizontal direction.

  Then, as understood from FIG. 2, a substantially mountain-shaped convex portion protruding toward the waterproof sheet 4 side functions as the ventilator edge portion 5, and the mortar-coated outer wall vent layer forming member 1 in the present invention is used. Is formed by integrally forming a ventilation cylinder edge portion 5 serving as a ventilation cylinder edge and a rib lath portion. And the trough part formed between the said ventilation trunk edge parts 5 and 5, ie, a space part, is formed as space for ventilation layers.

  By the way, a plurality of ventilator rim portions 5 forming concave grooves formed by being bent so as to protrude substantially in a mountain shape toward the waterproof sheet 4 are provided at intervals, as shown in FIG. As described above, the mortar-coated outer wall air-permeable layer forming member 1 is formed in a cross-sectional shape that is substantially concave and convex in the horizontal direction. The rib portion can be prevented from being cut.

  The manufacturing method of the mortar-coated outer wall ventilation layer forming member 1 will be described. First, a plurality of groove ribs 2 extending in the horizontal direction are provided at intervals, and a mesh portion is provided between the groove ribs 2 and 2. A waterproof sheet 4 is adhered to one surface side of the lath material 3 formed with a grooved rib 2 of a metal iron plate material having different elongation rates, a lath material 3 composed of a mesh portion of a mesh iron plate material, and a waterproof sheet of the sheet material A forming material is formed by stacking 4 in a substantially planar shape.

  Here, the affixing of the waterproof sheet 4 to the lath material 3 is performed by first applying an adhesive such as glue to the waterproof sheet 3 and placing the lath material 3 thereon, and then applying a certain pressure to the lath material 3. And the waterproof sheet 3 are integrated. There is also a method in which the lath material 3 and the waterproof sheet 3 are put together at a predetermined position and stitched together by stitching or the like.

  Thus, the waterproof sheet 4 is formed so as to form the ventilator edge 5 of the substantially concave groove perpendicular to the groove rib 2 from the surface side to which the waterproof sheet 4 is not attached. Is stamped and press-molded so as to protrude into a substantially trapezoidal ridge toward the surface to which is attached.

  At the time of the press molding, the opening side corner portions 17 and 17 of the ventilating drum edge portion 5 forming the substantially concave groove are press-molded with R so that the press stress can be dispersed, and a number of press stress vectors are used. It is preferable to disperse in the angle. Thereby, it is possible to prevent the opening-side corner portions 17 of the ventilator rim portion 5 from being broken by press stress.

  In this way, the ventilator edge 5 is press-molded. By repeating this press-molding operation, a plurality of the ventilator edges 5... Can be formed at intervals. I can do it.

  Further, the height of the ventilator edge portion 5 is, for example, in accordance with the design dimensions of the building so as to have a height that allows sufficient ventilation in the vent layer 7 formed between the ventilator edge portions 5, 5. It is possible to make the height 16,18,20mm free.

  Thus, the mortar-coated outer wall ventilation layer forming member 1 according to the present invention does not require a conventional vertical ventilation cylinder edge by integrally forming the ventilation cylinder edge part 5 serving as the ventilation cylinder edge and the rib lath. Therefore, it is possible to save the material cost of the ventilator rim and the labor for attaching the ventilator rim, and to reliably form the mortar-coated outer wall vent layer.

  Mortar 8 is applied to the outside of the mortar-coated outer wall aeration layer forming member 1 attached to the outside of the building structural housing 6 and is the final step of mortar-coated outer wall construction.

In addition, the ventilation end fixed tree 11 in which the air inflow hole was each provided is attached to the upper end and lower end of the mortar coating outer wall part of the building in which the said ventilation layer 7 was formed.

  The upper and lower ends of the mortar-coated outer wall portion of the building in which the air-permeable layer 7 is formed are opened, and the thickness of the air-permeable layer 7 can be maintained by attaching the air-end fixed tree 11 to each of the openings. At the same time, by providing a plurality of penetrating air inflow holes in the vent end fixed wood 11, sufficient air permeability can be ensured.

  In particular, the lower end ventilation end fixed wood 11 has both functions of a draining material and a parting edge. In addition, although the material of the ventilation end fixed tree 11 is not specifically limited, you may use the thing made from resin.

  The outside air that has flowed in from the air inflow hole of the lower end ventilation end fixed wood 11 passes through the plurality of ventilation layers 7 formed by the mortar-coated outer wall ventilation layer forming member 1 and continues to rise in the wall body. It flows into the atmosphere from the back vent or the back vent.

  In addition, you may provide the fixed ventilation-like horizontal ventilation trunk edge 12 in which the air inflow hole extended in the horizontal direction was provided in the ventilation layer 7 formed between the said waterproof sheet 4 and the moisture-permeable waterproof sheet 10. FIG. Thereby, while being able to hold | maintain the thickness of the ventilation layer 7, ventilation property can fully be ensured by providing the several air inflow hole which penetrates the horizontal ventilation trunk edge 12. As shown in FIG.

  Next, the mortar coating outer wall ventilation layer forming construction method of the building in which the mortar coating outer wall ventilation layer forming member 1 is continuously laid will be described.
