Description

  The present invention relates to a ventilation wall forming method having a heat shielding function, a heat insulating function, a moisture exhausting function, an exhaust function, a dew condensation preventing 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, an air layer having a thickness of about 20 mm is provided 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).

JP 09-119175 A JP 09-144152 A Japanese Patent Laid-Open No. 11-241427 JP 11-293801 A JP 2000-291169 A JP 2003-328460 A

  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 method for forming a ventilation wall on an outer wall, a vertical flat fixing portion, an upper surface protruding outward from the upper end of the fixing portion, and a tip of the upper surface downward. A length formed from a suspended side surface, a lower surface projecting outward at the lower end of the side surface, and a decorative surface projecting upward at the front end of the lower surface, and a ventilation and running water hole formed at regular intervals on the upper surface and the lower surface A horizontal parting edge is fixed horizontally and continuously to the base part of the wall base, and a dry wall material with a horizontal wall and a ventilation groove formed on the back side is inserted into the parting part space to ventilate from the base part to the eaves part. The present invention provides a method for forming a ventilation wall in which a passage is formed.

According to the ventilation wall forming method of the present invention,
(1) It has an exhaust function to release moisture, contaminated air, waste heat, etc. in the wall to the outdoors.
(2) It is possible to release moisture from the base and pillars to the outdoors.
(3) The air passage functions as an air layer and can make use of heat insulation.
(4) Waterproofness can be maintained.
(5) No condensation occurs in the ventilation path (wall).
(6) Since no condensation occurs, 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 ventilation groove is formed in the dry wall material and a ventilation / flowing water hole is formed at the parting edge, even if a horizontal dry wall material is used, a ventilation channel communicating from the base part to the eave part is formed. Can be formed.
There are features and effects.

Air conditioning is used to improve cooling efficiency, and in winter, heating is made more efficient, saving energy and reducing costs. This is because the ceramic-type outer wall material has a property of storing heat and gradually radiating heat because the specific gravity of the ceramic-type outer wall material is large, whereas the ventilation wall according to the present invention using the synthetic resin foam D1 as the core material D Since the dry-type wall material B used in the forming method 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 hollow B1 formed by recessing the back surface of the dry wall material B into a concave strip, and a portion where the bulging portion is recessed at a constant pitch to form a ventilation groove B2.
