Description

  The present invention relates to a draining material that waterproofs a gap (horizontal joint) between outer wall panels on an upper floor and a lower floor of a building or a gap between a foundation structure of a building and an outer wall panel.

  FIG. 1 shows a conventional draining material 1 that waterproofs a gap between outer floor panels of an upper floor and a lower floor of a building, and is inserted between wall base materials 2 of an outer wall panel 4 as shown in FIG. A drainage made of metal (mainly aluminum) comprising a mounting portion 3 to be attached and a cover portion 5 extending from the gap 9 between the outer wall panels on the upper floor and the lower floor and covering the upper end portion of the outer wall panel 4 on the lower floor to the front surface. It consists of a main body 6 and a rubber or resin sponge 7 that is bonded to the back surface of the cover part of the draining main body 6 and seals in close contact with the upper end of the outer wall panel 4 on the lower floor.

In addition to this, a drainage fitting as disclosed in Patent Document 1 below is known. As shown in FIG. 3, the draining metal fitting is integrally formed with a mounting portion 13 fixed to the body edge 11 with a screw or a nail 12, and the upper end portion of the outer wall panel 14 on the lower floor. A cover portion 15 that covers the front surface, and a second cover portion 16 that is integrally formed with the attachment portion 13 and covers the front surface from the lower end portion of the outer wall panel 14 on the upper floor. A sandwiching piece portion 17 that sandwiches the upper end portion of the outer wall panel 14 on the lower floor, and an elastically deformable contact piece portion 18 that comes into contact with the upper end portion of the outer wall panel 14 on the lower floor and prevents rainwater from entering.

  In the conventional draining material shown in FIG. 1, when rainwater blows from below in the mounted state shown in FIG. 2, the sponge 7 retains rainwater, which causes the outer wall panel 4 to corrode or mold, There is a concern that the draining material 1 may be rusted and adversely affect the outer wall panel 4 and the draining material 1. Further, the draining material 1 does not fit in a predetermined position due to the reaction force of the sponge 7, and there is a risk of floating in the direction of the arrow in FIG.

  On the other hand, in the draining metal fitting shown in FIG. 3, the elastically deformable contact piece 18 contacts and seals with the upper end of the outer wall panel 14, but the contact piece 18 is made of metal even though it is elastically deformable. Therefore, the sealing performance is inferior to that of the sponge, and the sealing performance is increased. Therefore, the stronger the pressing force, the more the reaction force increases and the cover portion 16 tends to float. In addition, since the draining metal fittings are made of metal, it is difficult to perform complex molding. For example, even when combined with a resin material, it is necessary to integrate the resin into the metal casing, Sex is complicated.

  An object of this invention is to provide the draining material which can solve the said problem of the seal | sticker by a sponge or a contact piece part.
