As a waterproofing measure at the end of the wall material, a sealing material may be applied so as to close the gap between a predetermined portion of the structural frame and the end of the wall material facing the predetermined portion. However, since the weather resistance of the sealing material is not sufficient, water may infiltrate from the wall material side of the building to the structural frame side by the waterproofing treatment that relies exclusively on the sealing material.

The present invention has been conceived under such circumstances, and an object thereof is to stop water suitable for achieving high water stopping property with respect to water intrusion from the wall material side of the building to the structural frame side. It is an object of the present invention to provide a water member, and a wall structure and a wall material construction method using such a water blocking member.

According to the first aspect of the present invention, a waterproof member is provided. This water blocking member includes a main body portion and a sealing member. The main body portion has a flat plate portion for attachment to the structural frame of the building and a wide portion located at one end edge thereof. The wide portion extends on both sides in the thickness direction of the flat plate portion at one end edge of the flat plate portion, and has a sealing member mounting surface on the side opposite to the flat plate portion. The seal member is attached at a position across the extension surface of the flat plate portion on the seal member mounting surface of the wide portion.

In this water blocking member, the sealing member may be fixed to the sealing member mounting surface of the wide portion and integrated with the main body portion, or may be a separate body from the main body portion and may be a sealing member at a construction site or the like. It may be closely fixed to the mounting surface.

The installation of the water blocking member on the structural frame can be performed, for example, as follows. First, a force is applied to the flat plate portion of the waterproof member in a state where the seal member is sandwiched between the wide portion of the waterproof member and the predetermined portion of the structural frame, and the seal member is directed toward the predetermined portion. It is pressed, for example, compressed and deformed to bring it into close contact with the predetermined location. Next, the flat plate portion of the water blocking member is fixed to another part of the structural frame. The wall material is fixed to the other part by sandwiching the flat plate portion of the water blocking member between the wall material and the other part of the structural frame.

As described above, the seal member of the water stop member is attached at a position where the extension surface of the flat plate portion crosses the seal member attachment surface of the wide portion.

Will be or will be placed.

Therefore, in the above-mentioned mounting work of the water stop member, the force received by the flat plate portion of the water stop member acts linearly and efficiently on the seal member crossed by the extension surface of the flat plate portion. Specifically, when the seal member sandwiched between the predetermined portion of the structural frame and the wide portion of the waterproof member is pressed toward the predetermined portion by applying a force to the flat plate portion, the flat plate portion receives the seal member. The force is transmitted through the flat plate portion and acts linearly and efficiently as a pressing force on the seal member crossed by the extension surface of the flat plate portion through the wide portion.

Such a linear pressing force transmission action is suitable for making the compressed state uniform in the sealing member that receives the pressing force. The higher the uniformity of the compressed state of the sealing member, the easier it is to realize high water stopping property or high waterproofness in the main water blocking member or the sealing member.

The compressed state of the sealing member that receives the pressing force is likely to be uniformed, and therefore, it is easy to realize high water stopping property or high waterproofness in the sealing member. Further, in this water blocking member, the more the extension surface of the flat plate portion and the mounting surface of the seal member in the wide portion are orthogonal to each other, or the angle at which they intersect is close to orthogonal, the more appropriate the installation of the water blocking member to the structural frame is. Easy to do.

In this water blocking member, one end of a wide portion of the flat plate portion in the thickness direction has a folded structure toward the sealing member on the sealing member mounting surface side. Such a configuration is suitable for hiding the seal member by the folded structure when the water blocking member is attached to the structural frame with the folded structure facing the wall material side. Further, when the folded structure portion abuts on the structural frame in addition to the sealing member, it is easy to obtain high water stopping property in this water blocking member.
