Description

  The present invention relates to a water stop structure between a roof of a lower house and an outer wall.

  As shown in FIG. 4 (a), a water stop plate 53 made of metal or the like is used as a water stop structure for stopping the boundary between the roof 51 of the lower house attached to the building and the outer wall 52 of the building. There is one in which one portion 53a is raised upward behind the outer wall surface material 57 and the other portion 53b is placed along the roof 51 of the lower house. Reference numeral 56 denotes a roofing.

  By the way, in this water stop structure, in order to make the water stop performance between the water stop plate 53 and the outer wall 52 high, the rising height dimension of the water stop plate 53 behind the outer wall material 57 is as large as possible. Then, as shown in FIG. 4 (b), immediately behind the portion where the rising portion 53a of the water stop plate 53 is inserted, there is another structural portion 59, for example, a building structure such as a frame structure material. Since there is a portion, it becomes difficult or impossible to insert the rising portion 53a of the water stop plate 53 from the outdoor side to the back side of the outer wall surface material 7. If one of the requirements is satisfied, the other requirement is not satisfied. In some cases, it is difficult to ensure sufficient water stopping performance.

  In view of the above-mentioned problems, the present invention provides a water stop between the roof and the outer wall of the lower house, which can secure a sufficient water stop performance and can also easily attach a water stop plate. It is an object to provide a water structure.

The above problem is that the boundary between the roof of the lower house and the outer wall is stopped by a water stop plate having a part that stands behind the outer wall material and a part that extends along the roof of the lower house. A waterproof structure between the outer wall and the outer wall,
Between the rising part of the said water stop board and the outer wall surface material side, the sealing material which stops water between them is interposed, The water stop between the roof and outer wall of a lower house characterized by the above-mentioned Solved by structure.

  In this water stop structure, since a sealing material is provided between the rising portion of the water stop plate and the outer wall surface material side to stop water between them, Even if the rising height is reduced, the sealing material can ensure the water stopping performance between the water blocking plate and the outer wall material, and thus the rising height of the water blocking plate behind the outer wall material. Since the size can be reduced, the water stop plate can be easily attached.

  In the above water stop structure, the sealing material is made of an elastic molded sealing material and is attached to the rising portion of the water stopping plate in advance, and the rising portion of the water stopping plate is raised behind the outer wall surface material. When it is interposed between the rising portion of the water stop plate and the outer wall surface side, the sealing material can be easily installed.

  Since the present invention is as described above, it is possible to easily attach the water stop plate while ensuring sufficient water stop performance.

  Next, the best mode for carrying out the present invention will be described with reference to the drawings.

  In the water stop structure of the embodiment shown in FIGS. 1 to 3, 1 is a roof of a lower house attached to the building, 2 is an outer wall of the building, and 3 is a water stop plate. In the roof 1 of the lower house, 4 is a rafter, a field board 5 is installed on the rafter 4, and a waterproof roofing 6 is installed on the field board 5.

  The outer wall 2 has a structure in which a foamed resin heat insulating material 8 for heat insulation is provided behind an outer wall material 7 such as a ceramic system, and a shaft structure material 9 is provided behind the outer wall material 7. A notch 10 is formed on the back side of the lower edge portion of the heat insulating material 8, and the notch 10 is used to open the water stop plate 3 between the foamed resin heat insulating material 8 and the frame structure material 9. An insertion portion 11 is formed.

  The water stop plate 3 is made of a metal plate, a composite plate of metal and resin, or a resin plate, and has a portion 3a standing behind the outer wall surface material and a portion 3b extending along the roof of the lower house. As shown in FIG. 3, at the boundary between the roof 1 of the lower house and the outer wall 2, from the outdoor side, the rising portion 3 a is inserted into the insertion part 11 on the outer wall 2 side from below, and then on the roof of the lower house. It is installed in such a manner that the portion 3b along the upper surface side of the roofing 6 of the roof 1 of the lower house is along.

  And the height dimension of the rising part 3a of the water stop board 3 is the limit which the upper edge part of the rising part 3a is inserted in the insertion part 11, and can form an overlapping part with the lower edge part of the foamed resin heat insulating material 8. The sealing material 12 is interposed between the rising portion 3a of the water stop plate 3 and the foamed resin heat insulating material 8 in the overlapping portion, and the water stop plate 3 and the foamed resin heat insulating material 8 are That is, between the water stop plate 3 and the outer wall surface material 7 side is stopped.

  The sealing material 12 is made of, for example, an elastic molded sealing material such as an open-cell type sealing material obtained by foaming an EPDM rubber mixture. As shown in FIG. As shown in FIG. 3 and FIG. 1 (B), the rising portion 3a is attached to the upper edge of the rising portion 3a, and the rising portion of the water stopping plate 3 is inserted by inserting it into the insertion portion 11. It is sandwiched between the foamed resin heat insulating material 8 and the shaft assembly structure portion 9 together with the portion 3 a and compressed, and is interposed between the water blocking plate 3 and the foamed resin heat insulating material 8.

  In the water stop structure, a sealing material 12 is provided between the rising portion 3a of the water stop plate 3 and the foamed resin heat insulating material 8 on the outer wall surface side to stop water between them. Therefore, even if the rising height dimension of the water stop plate 3 behind the outer wall surface material 7 is reduced, the sealing material 12 ensures the water stop performance between the water stop plate 3 and the outer wall surface material 7 side. Thus, since the height dimension of the rising portion 3a of the water stop plate 3 behind the outer wall surface material 7 can be reduced, the water stop plate 3 can be easily attached from the outdoor side.

  In particular, the sealing material 12 of the present embodiment is made of a dry elastic molded sealing material, and is attached in advance to the upper edge of the rising portion 3a of the water stop plate 3, and this water stop plate 3 with the seal material is provided. By simply inserting the rising portion 3a into the insertion portion, the sealing material 12 can be easily installed because it is interposed between the rising portion 3a of the water blocking plate 3 and the outer wall surface material 7 side. It can be carried out.

  Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the case where the rising portion 3a of the water blocking plate 3 is inserted between the foamed resin heat insulating material 8 and the shaft assembly structural material 9 is shown, but there is a limit to the specific structure of the outer wall. Further, the rising portion 3a of the water blocking plate 3 only needs to be raised behind the outer wall surface material and more outdoors than the building structure portion such as the frame structure material.

An embodiment is shown, a figure (I) is a section side view of a water stop structure part, and a figure (B) is a perspective view of a water stop board. FIG. 1A is a schematic perspective view showing a boundary portion between the outer wall of the building and the roof of the lower house, and FIG. It is a cross-sectional side view which shows the attachment method of a water stop plate. FIG. 1A is a cross-sectional side view of a water stop structure portion, and FIG. 2B is a cross-sectional side view showing a method of attaching a water stop plate.
