I. In the conventional wall structure shown in FIGS. 10 to 12, the sealing material 7 has sufficient waterproof properties if it is water-tightly attached to the tree end faces 6b, 6b. When the seal breakage phenomenon that separates from the tree end surface 6 b occurs, water such as rainwater flows into the back side of the wall material 6.

The present invention can prevent or suppress the inflow of water to the back side of a wall material or an adjacent member (window material, door frame, protruding corner material, parting material, etc.) even if such a seal breakage occurs. An object is to provide a wall structure using a joiner.

II. In the conventional wall structure shown in FIGS. 10 to 12, the sealing material 7 is firmly attached to the top portion 4 or 13. Therefore, when it is going to displace in the direction (wall width expansion direction) in which the wall materials 6 are separated from each other, the expansion in the joint width expansion direction of the sealing material 7 is constrained by the top portions 4 and 13, and the sealing material 7 and the wood end surface 6b. A large stress is generated in the direction in which the two are peeled from the interface, and the seal is likely to be broken.

In one aspect of the present invention, an object of the present invention is to provide a wall structure using a joiner that can prevent such seal breakage.

Wall structure of the present invention (Claim 1) is arranged joiners in joints between or between wall material between the wall member and the adjacent member, met wall structure sealing material is filled in said purpose fabric part In the wall structure in which the sealing material filled in the joint portion adheres to the wall member facing the joint portion or the tree end surface of the adjacent member, the joiner rises from the back plate portion and the front surface of the back plate portion. The upright portion has an upright portion, and the upright portion is disposed in the joint between the wall materials or between the wall material and the adjacent member, and at least a part of the portion in contact with the wall material or the adjacent member has a soft material. The soft material is provided at least at a part of the side of the upright part and a part of the front part of the upright part, and the soft material includes the upright part and the end face of the tree. Characterized by being tightly pressed by the wood and closely contacting the end face of the tree It is.

In the wall structure of the present invention, a soft material is provided on at least a part of a portion in contact with the wall material of the joiner or an adjacent member (window material, door frame, protruding corner material, parting material, etc.). The material exerts a sealing action between the joiner and the wall material or the adjacent member. Therefore, even if a seal breakage occurs in the sealing material, it is possible to prevent water from flowing into the deeper side than the soft material .

In addition , since a soft material is interposed between the side face of the wall member and the side surface of the adjacent member or the upright portion, by increasing the width direction width of the soft material provided on this side portion, The sealing effect can be made sufficiently high.

Furthermore, the wall structure of the present invention is also provided with a soft material at the front part of the standing part. The soft material provided at the front portion of the upright portion does not contact the wall material or the adjacent member, but contacts the sealing material filled in the joint portion in front of the joiner. That is, in the wall structure of this, the soft material is interposed between the front portion of the sealing material and the standing part. In this wall structure, when the wall materials or the wall material and the adjacent member are displaced in the joint width increasing direction, the expansion of the sealing material is hardly restricted by the front portion of the upright portion. That is, since the soft material is interposed between the front portion of the upright portion and the sealing material, the sealing material extends relatively freely to the joint portion. Therefore, excessive stress is not generated near the interface between the sealing material and the end face of the wall material or near the interface between the sealing material and the adjacent member, and separation between the sealing material and the end face of the wall material or the adjacent member side surface is prevented. Become.

In the wall structure of claim 2, since the soft material is continuous in the longitudinal direction of the joiner, the sealing effect is excellent.
