Description

  The present invention improves the moisture-proof technology inside the handrail wall. More specifically, the moisture-proof cover of the handrail wall that is lightweight and does not rust, and can reliably prevent rainwater from entering the inside of the handrail wall. In addition, the present invention relates to a moisture-proof structure of a handrail wall that can effectively exhaust moisture inside and prevent condensation while ensuring air permeability.

  As is well known, handrail walls (parapets) are installed on balconies and verandas of houses and the like, and this handrail wall is configured by covering the top end portion of the standing wall body with a headboard member.

  By the way, since the inside of the handrail wall is hollow, there is a possibility that rainwater may blow in from the gap between the headboard members and moisture may directly enter the inside.

  Conventionally, in order to prevent such intrusion of moisture, there is a structure in which a handrail wall is provided with a waterproof structure, and a wide variety of such structures are disclosed (for example, see Patent Document 1).

  On the other hand, there is a type in which the top end portion is completely closed with a bracket or the like for attaching the head member, and the inside of the wall surface is airtight.

  However, it is difficult to ensure complete airtightness because moisture inevitably enters the wall surface even from a slight gap.

  Moreover, as long as the top of the wall is closed incompletely, convection does not occur inside the wall, and the intruded moisture is trapped, while heat such as heating is conducted from the building to the internal space, There was a problem that condensation occurred due to a temperature difference from the outside air.

In addition, the cover member such as a bracket is often made of a metal such as a steel plate, and is easily rusted and corroded in the high humidity state as described above. There is a problem.
