Description

  The present invention relates to a structure of a lower end portion of an outer wall material used for a base portion of an outer wall material of a building or a structure.

  In general, when constructing a horizontal outer wall material, a structure in which a starter is formed on the foundation part of the foundation, and a sealing material is formed between the foundation part and the outer wall material to prevent wind and rain from entering the inside of the frame. Has been. (For example, refer to Patent Documents 1 and 2).

JP-A-11-310966 Patent No. 3448219

  However, Patent Documents 1 and 2 are structures in which a sealing material is formed between the starter and the base portion, and wind and rain enter the back of the outer wall material from between the outer wall material and the starter, and promote deterioration of the casing and the outer wall material. There was a problem.

  In order to solve such drawbacks, the present invention provides a vertical flat fixed surface, a receiving surface protruding from the fixed surface to the outdoor side, and a protrusion protruding upward and downward on the upper and lower surfaces of the receiving surface. A long member starter formed from a stop surface, a locking groove formed by the locking surface and the fixing surface, and a contact surface protruding upward and downward from the tip of the receiving surface. And a vertical planar fixed piece, and a long-shaped seal receiving member formed from a receiving piece with the lower end of the fixed piece projecting indoors, and the starter is connected to the lower end of the outer wall housing And a lower end portion structure of the outer wall member integrated with the fixed piece of the seal receiving member in contact with the receiving surface of the starter.

  According to the structure of the lower end portion of the outer wall material according to the present invention, (1) preventing the formation of a gap reaching the housing at the lower end portion between the drainer, the starter / seal receiving member, and the outer wall material, Deterioration due to wind and rain can be prevented. (2) Pests such as insects do not enter the inside of the enclosure. (3) A sufficient adhesion surface can be secured and waterproofness can be maintained over a long period of time. (4) Since the starter / seal receiving member is formed by two members of the starter and the seal receiving member, the starter / seal receiving member can be formed only at a necessary portion, the workability is improved, and the cost is reduced. (5) Since the locking surface protruding upward and downward and the contact surface protruding upward and downward are formed so as to be symmetrical with respect to the receiving surface, they can be fixed upside down. There are features and effects.
