[0017]

In the invention according to claim 1, the joint structure is arranged on the outer side of the irregular sealing material and the irregular sealing material to be injected into the gap, and the joint structure is provided in the end face region of the outer wall member constituting the gap. The fixed shape sealing material that is in close contact with and closes the gap, and the irregular shape sealing material has at least a part thereof in contact with both end surfaces of the outer wall member facing each other, so that the gap between the outer wall members is Since the double-sealing is performed by the regular sealing material and the irregular sealing material, high waterproofness can be secured. Further, even in the portion where the seam of the standard sealing material occurs, the seam of the standard sealing material can be filled with the non-standard sealing material,
High waterproofness can be obtained.

Moreover, since the fixed shape sealing material closes the gap, the fixed shape sealing material is covered with the fixed shape sealing material and is not exposed, and is not exposed to ultraviolet rays or rain, so that the fixed shape sealing material is susceptible to deterioration due to external factors. The material can be prevented from deterioration and the appearance is good.

Further, since the sealing structure is composed of the irregular sealing material and the regular sealing material, it is necessary to uniformly fill the gap with an appropriate amount of irregular sealing material necessary for waterproofing. Compared with the joint structure to be formed, the joint forming operation is easy and does not require a high degree of skill.

Even in the portion where the seam of the regular sealing material occurs, the seam of the regular sealing material can be filled with the irregular sealing material, so that high waterproofness can be obtained.

According to the second aspect of the present invention, the joint structure is arranged on the inner side of the irregular sealing material, is attached to the end surface of the outer wall member, holds the regular sealing material, and has the irregular sealing. As with the invention according to claim 1, since the back wall member is configured to include a backup member for preventing the material from flowing into the back side of the outer wall member, in addition to ensuring high waterproofness, the outer wall member is also secured. Even when there is no backup material in the member on the building side such as when the bottom of the gap is deep, it is possible to prevent the inflow of the irregular sealing material, and it is possible to inject the irregular sealing material into the gap.

Further, since the regular sealing material is held by the backup member, the regular sealing member can be stably attached.

It is the same as the invention of claim 1 that the deterioration of the irregular sealing material is prevented and the joint forming work is easy.

According to the third aspect of the present invention, since the fixed shape sealing material extends to the end face side of the outer wall member and has the seal piece, the outer wall member may have some dimensional errors and design differences. Even if the widths of the gaps are different from each other, this seal piece is elastically deformed and closely adheres to the end surface of the outer wall member to reliably close the gap. Therefore, the difference in the width of the gap can be dealt with, and the number of parts can be reduced.

According to the invention of claim 4, the backup member has a seal piece which extends toward the end face side of the outer wall member and is in close contact with the end face of the outer wall member.
Similar to the described invention, it is possible to cope with the difference in the width of the gap between the outer wall members.

According to the fifth aspect of the present invention, the cover portion of the fixed-shape sealing material covers the projected corner portion of the outer wall member, thereby improving the appearance of the projected corner portion. Conventionally, in the projected corner portion of the outer wall, that is, in the projected corner portion of the outer periphery of the building, the external appearance is poor when the end surface of the outer wall member is exposed, so a corner accessory having a substantially L-shaped outer wall member is used. The structure was taken. According to the present invention, a corner accessory is not required, cost can be reduced, and construction is easy.

According to the sixth aspect of the invention, it is possible to shorten the construction period by simplifying the construction on the spot without requiring the joint forming work on the spot.

In the invention according to claim 7, the gap between the sash frame and the outer wall member provided on the outer wall main body around the sash frame is high because it is sealed by the regular sealing material, the irregular sealing material and the backup member. It is possible to ensure waterproofness. Further, even in the portion where the seams of the regular sealing material occur, the seams of the regular sealing material can be filled with the irregular sealing material, so that high waterproofness can be obtained. In addition, the backup member prevents the irregular sealing material from flowing into the back surface of the outer wall member, so even if there is no backup material in the building side member such as the gap between the sash frame and the outer wall member, It is possible to inject an appropriate amount of irregular shaped sealing material into the space, and it is possible to reliably close the gap.

Since the fixed-shape sealing material is held by the backup member, the fixed-shape sealing member can be stably attached, deterioration of the irregular-shaped sealing material can be prevented, and the joint forming work can be easily performed. This is the same as the invention according to claim 2.

According to the invention of claim 8, the backup member has a seal piece which extends toward the outer wall member and is in close contact with at least one of the end surface and the back surface of the outer wall member. It is possible to deal with the difference in the width of the gap, the gap can be reliably closed, and the inflow of the irregular sealing material can be surely prevented.

According to the ninth aspect of the invention, at least one of the backup member and the regular sealing material has a sealing piece that extends toward the sash frame and is in close contact with the end face of the sash frame. Thus, it is possible to cope with a slight difference in the width of the gap, and it is possible to reliably close the gap.
