Description

  The present invention relates to a rain closing structure.

  When forming an opening for passing piping through the outer wall of a building, an opening reinforcing member (corner angle) having an L-shaped cross section may be provided in an annular portion surrounding the opening (see Patent Document 1). In this case, if the gap between the outer wall and the opening reinforcing member is closed with a caulking material, the space between the opening reinforcing member and the pipe is covered with a seal plate, and the seal plate is welded to the opening reinforcing member, rainwater enters the inside from the opening. It is possible to perform a rain performance to prevent it.

JP-A-2005-240442

  By the way, when the seal plate is welded to the opening reinforcing member, the opening reinforcing member is deformed by the heat of welding, and there is a possibility that a gap between the outer wall and the opening reinforcing member is widened. For this reason, the caulking work for closing the gap between the outer wall and the opening reinforcing member is performed after the welding work.

  Here, when the building team that constructs the building and the piping team that constructs the piping are separated, the caulking work described above is performed by the building team, and the welding work is performed by the piping team. Then, after the building was completed and handed over from the building team to the piping team, after the piping team carried out the above-mentioned welding work in the construction of the pipe and rain, it was further transferred from the piping team to the building team. The handing over is performed and the caulking work is performed. As described above, in the conventional work of rain, the delivery is performed many times, which is inefficient.

  This invention is made | formed in view of such a situation, Comprising: It aims at providing the rain closing structure which can perform a caulking operation | work before a welding operation.

  A rain closing structure according to an aspect of the present invention is a rain closing structure that prevents rainwater from entering an indoor through an opening of an outer wall through which a pipe passes, and is provided along an annular portion of the outer wall that surrounds the opening. An opening reinforcing member, a caulking portion formed of a caulking material that closes a gap between the outer wall and the opening reinforcing portion, and a seal plate that covers between the opening reinforcing member and the pipe, the opening reinforcing member An inner peripheral portion located on the inner peripheral surface side of the annular portion, an outer surface portion located on the outdoor surface side of the annular portion, and an extension portion extending from the outer surface portion toward the center of the opening. The outer edge of the seal plate is welded to the extension of the opening reinforcing member.

  According to this configuration, since the seal plate is welded to the extension portion located on the opening side of the opening reinforcing member, the heat of welding is hardly transmitted to the outer surface portion located on the outer wall side. For this reason, since the gap between the outer wall and the outer surface portion, that is, the gap between the outer wall and the opening reinforcing member is difficult to spread even when the welding operation is performed, the caulking operation can be performed before the welding operation.

  In the rain closing structure, the outer wall may be a concrete wall, and the opening reinforcing member may be embedded in the outer wall.

  When the outer wall is a concrete wall, the opening reinforcing member can be firmly fixed to the outer wall by embedding the opening reinforcing member when the outer wall is formed.

  In the rain closing structure, the outer wall may be an ALC wall, and the opening reinforcing member may be bolted to the outer wall.

  When the outer wall is an ALC wall, the opening reinforcing member cannot be embedded when the outer wall is molded, but the opening reinforcing member can be firmly fixed to the outer wall by bolt connection.

  As described above, according to the above rain closing structure, the caulking work can be performed before the welding work.

  In addition, the main function of the blindfold plate 40 of this embodiment is not to prevent rainwater from flowing into the indoor space, but to secure a space for filling the filler 43 and not to impair the aesthetics from the indoor side. There is to do.

<Construction procedure>
Then, the construction procedure of the rain closing structure 100 which concerns on this embodiment is demonstrated. In this embodiment, the construction of the rain closing structure 100 is performed by a building team that constructs a building and a piping team that constructs piping. First, the outer wall 101 is formed by a building team using a mold so that the opening 103 is formed. During the molding, the opening reinforcing member 10 is embedded in the annular portion 105 surrounding the opening 103.

  Subsequently, the construction team 20 closes the gap between the outer edge of the first opening reinforcing member 11 and the outer wall 101 of the opening reinforcing member 10 with the caulking material to form the caulking portion 20. Thereafter, the construction team hands over to the piping team, and the subsequent work is performed by the piping team.

  The piping team passes the piping 102 through the opening 103 of the outer wall 101 and attaches the seal plate 30 so as to cover the space between the first opening reinforcing member 11 and the piping 102. This attachment is performed by welding the outer edge of the seal plate 30 to the extension 15 of the first opening reinforcing member 11.

  Here, when the seal plate 30 is welded to the first opening reinforcing member 11, the heat of welding is transmitted to the first opening reinforcing member 11, and the first opening reinforcing member 11 may be deformed. However, in this embodiment, the seal plate 30 is welded not to the outer surface portion 14 of the first opening reinforcing member 11 but to the extension portion 15 closer to the center of the opening 103 than the outer surface portion 14, so that the heat of welding is the outer surface portion 14. It is hard to be transmitted to. Therefore, the outer surface portion 14 is not easily deformed by the heat of welding, and the gap between the outer surface portion 14 and the outer wall 101 is difficult to expand. Therefore, even if the welding operation is performed after the above caulking operation, the gap between the opening reinforcing member 10 and the outer wall 101 is difficult to widen, so there is no need to redo the coking operation.

  Subsequently, a heat insulating material 104 is attached to the pipe 102 and a racking process for protecting the heat insulating material 104 is performed. Thereafter, the filler 43 is filled between the heat insulating material 104 and the annular portion 105 of the outer wall 101. Further, the blindfold plate 40 is attached to the indoor side portion of the second opening reinforcing member 12 so as to cover the filled filler 43. This attachment is performed by welding the blindfold plate 40 to the outer surface portion 17 of the second opening reinforcing member 12. This welding need not be seal welding, and may be spot welding or the like.

  Here, when the blindfold plate 40 is welded to the outer surface portion 17 of the second opening reinforcing member 12, the second opening reinforcing member 12 is deformed by the heat of welding, and the gap between the second opening reinforcing member 12 and the outer wall 101 is enlarged. There is a fear. However, normally, rainwater does not flow into the indoor space through the gap between the second opening reinforcing member 12 and the outer wall 101, so even if the gap between the second opening reinforcing member 12 and the outer wall 101 increases, the second There is no particular problem if the opening reinforcing member 12 is fixed to the outer wall 101.

  The above is the construction procedure of the rain closing structure 100 according to the present embodiment. As described above, according to the present embodiment, even when the seal plate 30 is welded to the first opening reinforcing member 11, the gap between the outer surface portion 14 and the outer wall 101 is difficult to expand, so the caulking operation is performed before the welding operation. It becomes possible. Therefore, it is not necessary to deliver from the piping team to the construction team again after the construction team has handed over to the piping team. As a result, it is possible to efficiently perform the work of rain.

(Second Embodiment)
Next, the rain closing structure 200 according to the second embodiment of the present invention will be described. In the second embodiment, the same or corresponding components as those of the first embodiment are denoted by the same reference numerals, and redundant description is omitted. FIG. 5 is a longitudinal sectional view of the rain closing structure 200 according to the second embodiment.

  The second embodiment is different from the first embodiment in which the outer wall 101 is a concrete wall in that the outer wall 101 is an ALC (Autoclaved Lightweight Aerated Concrete) wall. ALC walls are usually thinner than concrete walls because there are no rebars inside. The ALC wall is a precast product that is manufactured in advance in a factory and is carried to a construction site. Therefore, in the second embodiment, the opening reinforcing member 10 is not embedded in the outer wall 101 and is fixed to the outer wall 101 by bolting. Specifically, as shown in FIG. 5, the second opening reinforcing member 12 is fixed to the outer wall 101 by bolts 51, and the first opening reinforcing member 11 is welded to the second opening reinforcing member 12. In addition, the work which fixes the opening reinforcement member 10 to the outer wall 101 is performed by the building team, and then the caulking work is similarly performed by the building team.

  In the second embodiment, the opening reinforcing member 10 includes the first opening reinforcing member 11 and the second opening reinforcing member 12 as in the first embodiment. However, the first opening reinforcing member 11 and the second opening reinforcing member 12 are joined to each other. Specifically, as shown in FIG. 5, the inner peripheral portion 13 of the first opening reinforcing member 11 is located closer to the pipe 102 than the inner peripheral portion 16 of the second opening reinforcing member 12. The first opening reinforcing member 11 and the second opening reinforcing member 12 are joined by welding.

  The rain closing structure 200 according to the second embodiment is different from the rain closing structure 100 according to the first embodiment as described above, but the seal plate 30 is welded and joined to the extension 15 of the first opening reinforcing member 11. This is the same as the rain closing structure 100 according to the first embodiment. Therefore, even in the rain closing structure 200 according to the present embodiment, the gap between the opening reinforcing member 10 and the outer wall 101 is difficult to expand when the seal plate 30 is welded to the opening reinforcing member 10. Therefore, it is possible to perform the caulking work before the welding work, and as a result, the work of raining can be performed efficiently.
