Description

  The present invention relates to a building sealing material and a waterproof structure of a building using the same. More specifically, the present invention relates to a building sealing material that seals a space between an upper part of a building foundation member and a lower part of an outer wall.

Conventionally, as shown in FIG. 5, a space M is provided between a concrete base member 101 of a building and a lower portion of an outer wall 102 provided at a position protruding outward from the base member 101. Yes. On the indoor side of the outer wall 102, a horizontal column 103 is provided on the upper portion of the base member 101, and a vertical column 104 is provided thereon.
An aluminum draining member 5 is usually provided so as to cover the space M from the outdoor side. The draining member 5 has a substantially L-shaped cross section having a bottom surface 5a and a vertical surface 5b, and extends in the horizontal direction in which the base member 101 extends (direction perpendicular to the paper surface of FIG. 5). On one end side of the draining member 5, a standing piece 5 c provided with a sponge S on the indoor side is formed and faces the outdoor side of the base member 101.
In addition, a receiving piece 5 d extending toward the indoor side is formed on the other end side of the draining member 5, and faces the outdoor side of the outer wall 102.
Although not shown, a plurality of holes (punching holes) are formed in the bottom surface 5a of the draining member 5, and water flowing along the bottom surface 5a is discharged to the outside through the holes. The holes also keep air permeability.

  In the state in which the draining member 5 is attached, the sponge S provided on the standing piece 5c elastically contacts the outdoor side upper part of the base member 101, and supports the outdoor side lower part of the outer wall 102 by the receiving piece 5d. .

  However, since the sponge S is fixed to the standing piece 5c of the draining member 5 with a double-sided adhesive tape or the like, there is a problem that fixing requires a work time and the release paper becomes dust. In addition, when the sponge S is used, there is a concern that mold, algae, and the like may be generated in the sponge S due to the rain water being absorbed by the sponge S. Furthermore, rainwater may enter the indoor side from a plurality of holes H provided on the bottom surface 5a of the draining member 5 during strong winds.

The attachment can be performed very easily.
According to this, since a fixing tool such as a double-sided tape is not particularly required, the attaching operation can be performed in a short time, and no release paper is generated, so that no waste is generated.
At this time, the seal portion integrally formed with the mounting base elastically contacts the base member, so that the interior and the exterior can be reliably sealed without using the sponge as shown in the conventional example.
Thereby, since it is not necessary to use sponge for a building sealing material, water can be absorbed by long-term use, and generation of mold and algae can be prevented.
Moreover, since the several hole is formed in the bottom face of the draining member, it is excellent in air permeability. Then, rainwater that jumps into the room from the outside through the formed hole due to strong wind or the like is received by a standing part that is integrally formed on the mounting base part having a substantially U-shaped cross section of the building sealing material and extends upward. Since it is rebounded together, it is further prevented that water enters the indoor side.
In addition, by tilting the upright portion toward the outdoor side, rainwater that jumps into the room from the outside through the formed hole can be effectively repelled.

  As mentioned above, according to the building sealing material of the present invention and the waterproof structure of a building using the same, it can be easily attached to an existing draining member.
