Description

  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, 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 vertical flat fixed portion, an upper surface that protrudes outward from the lower end of the fixed portion, a side surface that hangs downward from the top end of the upper surface, and a lower end of the side surface. A long starter formed from a lower surface projecting in the direction and a decorative surface projecting upward at the tip of the lower surface, and a ventilation and running water hole formed at regular intervals on the upper surface and the lower surface, It provides a ventilation wall structure in which a dry wall material, which is fixed horizontally and continuously in the section, is inserted horizontally in the starter space and a ventilation groove is formed on the back side, is inserted, and an air passage is formed from the base to the eaves. is there.

According to the vent wall structure 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 in the starter, an air passage that communicates from the base part to the eaves part is formed even if a horizontal dry wall material is used. can do.
