Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of forming a pipe space in a unit building and a structure of the pipe space.

[0002]

BACKGROUND ART A building such as an apartment house or a general house is provided with a pipe space for connecting a pipe such as a water supply pipe, a drain pipe, or a gas pipe, and this pipe space is formed over the upper and lower floors. To be done. Conventionally, for example, in a frame building and a panel construction building, pipe space constituent walls are provided on the lower and upper floors at a construction site, and pipe spaces are provided by connecting these constituent walls up and down.

[0003]

According to the above conventional method, it takes a lot of time and labor at the construction site to form the pipe space, and there is a problem in workability and cost. In addition, various pipes are laid in the pipe space, and if there is a gas pipe in these pipes,
Since the pipe space is required to have fire resistance, a pipe space structure that can sufficiently meet such a demand is required.

It is an object of the present invention to take advantage of the characteristics of a unit building in which a plurality of factory-manufactured building units are combined at a construction site, which makes it possible to easily construct a pipe space with less construction site work. It is in the place where we can provide the pipe space construction method of the formula building.

Another object of the present invention is to provide a pipe space structure for a unit-type building which can sufficiently meet the demand when the pipe space is required to have fire resistance.

[0006]

A pipe space construction method for a unit type building according to the present invention corresponds to the building units of a lower floor and an upper floor constituting a unit type building in a factory. Pipe space constructing wall is installed at the position, and at the construction site of the unit type building, by placing the upper floor building unit on the lower floor building unit, the pipe space constructing wall is connected and the pipe space straddling these building units. Is formed.

[0007] In the above, when an opening that can be opened and closed is formed in the pipe space constituting wall, after placing the upper-floor building unit on the lower-floor building unit at the construction site, these openings are operated by the opening. Connect building units together,
After this, the opening is closed.

Further, in the pipe space structure of the unit type building according to the present invention, the pipe space forming walls are formed at positions corresponding to each other in the lower floor and upper floor building units constituting the unit type building, and these pipe space structures are formed. It is characterized in that a wall is vertically connected to form a pipe space extending over a lower-floor building unit and an upper-floor building unit.

The present invention described above can be applied to both cases where fire resistance is not required in the pipe space.

Further, in the pipe space structure of the unit type building of the present invention, for example, a gas pipe is installed in the pipe space. Therefore, when fire resistance is required in the pipe space, the pipe space constituting wall Is formed by fire-resistant wall panels erected on the lower and upper floor building units, and a pipe space is vertically divided between the fire-resistant wall panels of these building units, and a fire-resistant partition member having a pipe insertion hole is arranged. Has been done. When soft refractory materials are provided on the upper and lower surfaces of this fire-resistant partition member, the upper end of the fire-resistant wall panel of the lower floor building unit and the lower end of the fire-resistant wall panel of the upper floor building unit are connected to these soft refractory materials. , The fire-resistant wall panels on the upper and lower floors are continuous with each other through the fire-resistant partition member without any gap.

When a soft refractory material is provided in the pipe insertion hole portion of the fireproof partition member, the pipe is inserted into the pipe insertion hole in close contact with the soft refractory material, and a gap is generated in the soft refractory material. Disappear.

[0012]

In the present invention, since the pipe space constituting walls are formed at the positions corresponding to each other of the lower floor and upper floor building units at the time of manufacturing in the factory, the upper floor above the lower floor building unit at the construction site. When the building unit is placed, the pipe space constituting walls are connected to each other to form the pipe space, so that it is possible to form the pipe space by reducing the labor and time of the work performed at the construction site.

If the pipe space constituting wall is formed of a fireproof wall panel and a fireproof partition member is provided between the lower floor and the upper floor, the pipespace can be made fireproof for each floor. When soft refractory materials are provided on the upper and lower surfaces of the fire-resistant partition member and in the pipe insertion hole, the fire-resistant partition member and the fire-resistant wall panel can be connected and the pipe can be inserted into the pipe insertion hole without creating a gap Airtightness can be obtained.
