Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a unit building and a building unit.

[0002]

2. Description of the Related Art Conventionally, as a piping installation structure of a building unit constituting a unit building, there is a structure in which piping is installed along a floor beam in a channel steel of a floor beam of the building unit.

[0003]

However, the prior art has the following problems. For pipes extending between adjacent building units, it is necessary to form notch pipe insertion portions in the floor beams of both building units, resulting in a decrease in the strength of the floor beams due to the cutouts.

[0004] After a pipe is installed inside a floor structure constituting a building unit, a floor surface material is attached on the floor structure, and a worker needs a floor beam without a floor surface material and a joist. It is necessary to arrange and fix the pipes in an unstable posture where the user stands on the floor and walks, resulting in poor pipe workability.

[0005] An object of the present invention is to easily install pipes under the floor of a building unit in a unit building composed of building units.

[0006]

According to a first aspect of the present invention, a pipe is installed along a floor beam in a channel steel of a floor beam in a girder direction of a building unit, and a space between adjacent building units is provided. Is a unit building with pipes connected under floor beams in the direction of the wife.

According to a second aspect of the present invention, a pipe is installed along a floor beam in a channel steel of a floor beam in a girder direction of a building unit, and a floor plate in a portion along the floor beam in the girder direction. Is divided from the floor plate near the center of the building unit, an opening is provided at an appropriate place of the floor plate along the floor beam, and a rising portion of piping is inserted on the opening and positioned on the floor surface. It is a unit building having a building unit consisting of

According to a third aspect of the present invention, piping is installed along the floor beam in the channel steel of the floor beam in the girder direction of the building unit, and the extra length of the end of the piping is provided. It is a building unit that is bent near the floor beam in the direction of his wife.

[0009]

According to the first aspect of the present invention, the following operations are provided. The plumbing passes through the interior of the channel steel that constitutes the girder floor beams of the building units, and is connected between adjacent building units under their floor beams. Therefore, pipes can be passed through components such as floor beams, floor beams, joists, etc. of the building unit without forming notches as much as possible, so that the strength of the floor components does not decrease. Furthermore, the number of components does not increase for each mode of the notch.

According to the second aspect of the present invention, the following effects are obtained. Before attaching the floorboard along the beam in the direction of the girder, the floorboard near the center of the building unit can be used as a scaffold for piping from above the floor to below the floor. And when sticking the floorboard along the beam in the direction of the girder, the rising part of the piping can be inserted on the opening provided in this floorboard and positioned on the floor surface, and the installation workability of the piping can be improved. Can be improved.

According to the third aspect of the invention, the following operation is provided. By bending the excess length of the end of the piping provided in the building unit near the floor beam in the direction of the wife, the end of the piping unit will be obstructed when it is transported inside the factory and transported to the construction site. It doesn't get frustrated and it doesn't hurt.
