In order to install the sheath pipe, the plumbing company excavates the concrete surface and opens a through hole that leads to the outside and inside of the building, so it takes time to install the pipe. Therefore, if the piping work for connecting the outside of the building and the inside of the building can be facilitated, the construction period can be shortened and the cost can be reduced.

  Then, an object of this invention is to provide the piping structure of the building which can aim at shortening of a work period and suppression of cost by being able to perform piping work easily.

In the building piping structure of the present invention, the underground piping buried outside the building is erected from the ground and penetrates the foundation beam erected from the foundation of the building, and the indoor piping in the building A piping structure of a building arranged in such a manner that the underground piping is erected from the ground, and the piping portion that penetrates the foundation beam is surrounded by an enclosure that hides exposure, and the piping portion is The soil is covered with planting soil disposed in the enclosure.
The building piping structure of the present invention excavates a through-hole for passing the pipe through the foundation by making the pipe buried outside the building through the wall surface of the foundation beam and being arranged inside the building. Since there is no need, piping work can be facilitated. Since the underground piping is erected from the ground and the piping part that penetrates the foundation beam is surrounded by an enclosure, the piping can be hidden from the surroundings, protecting the piping and improving the aesthetics Can be made. As the shielding means for hiding exposure of the pipe portion, the enclosure can be made into a flower bed or a field by covering it with planting soil arranged in the enclosure. Here, the piping includes not only a drain pipe and a water supply pipe but also a gas pipe, a power line, a telephone line, a pipe for passing an optical fiber, and a sheath pipe for inserting various pipes.

  It is desirable that the pipe in which the underground pipe is erected from the ground and the pipe that is formed as an indoor pipe penetrating the foundation beam are connected by an L-shaped pipe. By doing so, indoor piping can be piped without bending up and down only by connecting an L-shaped pipe to outdoor piping erected from the ground.

  The underground piping is erected from the ground, penetrates the foundation beam on one side of the building, becomes an indoor piping in the building, penetrates the foundation beam on the other side of the building, and is outside the building It is also possible to arrange it as underground piping buried. By providing the piping in the building in this way, the length of the piping from the building in the other direction can be shortened.

  The indoor pipe that penetrates the foundation beam on the other side of the building becomes a buried underground pipe, is arranged in another adjacent building, and further penetrates the foundation beam on one side of the other adjacent building. It becomes indoor piping in the other building, penetrates the foundation beam on the other side of the other building, becomes underground piping buried outside the building, and is continuously arranged to other buildings It is possible. By providing piping continuously in the buildings lined up in this way, piping to adjacent buildings can be shortened.

According to the present invention, it is not necessary to excavate a through hole for passing a pipe through a foundation, so that a pipe work can be facilitated. Therefore, the present invention can shorten the work period and reduce the cost.
Further, in the conventional piping structure, since piping is passed through the foundation, when cracks occur in the piping, the foundation portion through the piping cannot be excavated, so the piping cannot be replaced. Therefore, it is necessary to dig a new place or to make a new pipe by drilling a hole in the wall of the building. However, in the piping structure of the present invention, it is not necessary to excavate the frame itself when performing repair work. Therefore, the present invention can be easily repaired, and is excellent in maintainability.
