Description

  The present invention relates to a seal material used for an eaves back parting part, which is a joint part between an outer wall material and an eaves ceiling material of a building having a sloped roof, and a seal structure provided with the seal material.

  FIG. 1 shows a conventional example of a seal structure for an eaves parting part, and a sponge 3 is made of a hard resin or a metal as a sealing material for an eaves parting part at the end facing the outer wall surface of the eaves ceiling material 1. When the eaves ceiling material 1 is constructed, the sponge 3 is pressed against the surface of the outer wall material 4 to seal the part of the eaves back part.

  In addition to the above-mentioned sponge, a sealing material having a lip that elastically contacts the outer wall material surface is also known (Patent Document 1). This is the case shown in FIG. 2, which is composed of a water return material 8 integrally formed with a lip 9 that is attached to an eaves back edge 6 attached to the eave ceiling material 5 by a fixture 7 and pressed against the surface of the outer wall material 11. ing. In the figure, 12 is a vent hole.

  As shown in FIG. 1, when the surface of the outer wall material 4 is uneven, the sponge 3 as a sealing material does not come into contact with the bottom of the concave portion 4a, and a gap d is generated between the bottom of the concave portion. Small animals such as mice and bats may enter the attic. When the thickness of the sponge 3 is increased and the wrap amount a to the outer wall material 4 is increased as the sponge 3 reaches the bottom of the recess, the distance between the convex portion on the surface of the outer wall material 4 and the fixture 2 is narrow. When the sponge 3 hits the convex portion 4b and is compressed, the eaves ceiling material 1 is pushed to the left in FIG. 1 together with the fixture 2 by the reaction force of the sponge, and between the eaves ceiling material side end surface and the outer wall material surface. The gap is enlarged and the appearance is deteriorated.

  In order to cope with this problem, in Patent Document 2, as shown in FIG. 3, a sealing member 13 is made of a hard material, and is attached to a side end portion of the eaves ceiling member 14 via a fixture 15. And a soft portion 17 integrally formed with the holding portion 16 and extending obliquely downward in a direction away from the holding portion 16, and slits 18 are formed in the soft portion 17 at regular intervals in the longitudinal direction. When the eaves ceiling material 14 is constructed with the gap between the lip pieces 19, the surface of the outer wall material provided with the unevenness 20a, 20b individually without restraining the movement of the lip pieces 19 of the sealing material 13 by the adjacent lip pieces 19. The one which can be sealed following the above is disclosed.

  In the sealing material disclosed in Patent Document 2, as shown in FIG. 3, the lip piece 19 follows the unevenness 20a, 20b on the surface of the outer wall material well, and also contacts the bottom of the recess to form a gap between the bottom of the recess. Although it is difficult to occur, the lip piece 19 that hits the convex portion 20b can also be deformed within the range of the gap in the eaves parting part, and has the advantage of not causing problems such as widening the gap and impairing the appearance. There is still room for improvement.

  An object of this invention is to provide the sealing material for making it difficult for small animals, such as a mouse | mouth, to penetrate | invade further into an attic, and the sealing structure provided with this sealing material.

  The invention according to claim 1 is a sealing material used for an eaves parting part that is a joint part between an outer wall material and an eaves ceiling material of a building, facing the outer wall material surface and the eaves parting part together with the outer wall material surface It is attached to the side end surface or side end portion of the eaves ceiling material that constitutes the eaves ceiling material along the side end surface or side end portion, the bottom portion, the side wall portions that are integrally formed at both ends of the bottom portion, and the opposite side wall portions. It consists of a hollow seal part made of a rubber-like elastic body that has a curved or flat connecting part that is connected at the part, has flexibility, and elastically contacts the surface of the outer wall material that is formed in irregularities. The protrusion b is formed to be larger than the depth h of the bottom of the recess that forms the maximum depth of the irregularities formed on the surface of the outer wall material, and at least a portion that is elastically contacted with the surface of the outer wall material has a slit at the end surface on the eave ceiling material side It is characterized by being formed at appropriate intervals in the longitudinal direction along.
