Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated shaft unit of a building such as a high-rise building which is installed mainly in a pipe shaft space through which air conditioning and sanitary piping are collectively passed.

[0002]

2. Description of the Related Art In recent years, in the field of construction, with the increase in the height and height of buildings, several pipe shaft spaces have been provided in a building, and air conditioning and sanitary piping are put together above and below the space. In order to shorten the construction period of these equipment piping installation work and reduce the installation work by hand,
The above pipes for 2 to 3 floors are integrated into one pipe shaft unit at the factory, the unit is transported to the construction site, and the equipment is suspended by a lifting machine and installed. The method of completing the piping is taken.

In the above-mentioned conventional construction method, a shaft having a frame structure composed of these pipes and a frame for fixing the pipes is adopted, and a shaft unit in which an ALC panel is attached to a wall at a factory is known. Has been.
However, with the shaft unit of the above construction method, after installing in the shaft space of the building, it is necessary to further install the groundwork for finishing the building shaft space section and the finishing panel, etc. In addition to the problem of requiring labor and the construction period, there were problems in terms of construction quality and safety.

When transporting the shaft as described above from a factory to a construction site, the shaft is laid on a loading platform such as a trailer, transported, carried into the site, and lifted up using a lifting machine at the site. Lifting and installation will be carried out, but in order to prevent deformation of the pipe shaft unit when standing up during lifting, the whole unit is lifted up with a strong frame structure.

Therefore, in particular, in a shaft unit in which thin pipes and ducts having a small rigidity are assembled, a larger frame is required, and there is a problem that the material cost is increased accordingly.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art. The object of the present invention is to reduce the on-site work and shorten the construction period by improving the completion of the factory. In addition to improving safety and quality, the grounding or finishing panels for finishing the shaft space division are pre-installed at the factory to minimize unnecessary members and reduce the rigidity of the pipe unit into a shaft unit. To provide a prefabricated type shaft unit.

[0007]

The prefabricated shaft unit of the present invention for achieving the above object is a building 1
The required pipes and ducts are connected in a shaft unit that connects the frame structure consisting of the frame assembly frame and the shaft frame of the floors up and down by a predetermined number of floors and can suspend the inside of the shaft space of the building from above. It is constructed by mounting the foundation for finishing the shaft space division of the building or finishing panels on the shaft frame of each floor.

The shaft unit having the above structure is
By pre-installing the groundwork or finishing panels to the frame structure at the factory, on-site work is reduced, and since the frame frame is incorporated into the shaft frame structure, rigidity is improved and material waste is saved. it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings, which is a schematic perspective view for explaining a shaft unit according to the embodiment. First, this shaft unit can be hung from above in the shaft space of a building to be built by a lifting machine or the like. In this embodiment, the shaft unit is installed in the shaft space of the third floor. The upper, middle, and lower three-story frame structures are connected vertically.

Therefore, at each of the steel frame level portions from the third floor to the first floor, there are provided an upper frame joining frame 1, an intermediate frame joining frame 2 and a lower frame joining frame 3, and these respective frame bodies are provided. Frames 1, 2 and 3 take in the frame steel frame as much as possible, and open a gap more than the thickness of the floor slab in the upper part of each frame frame 1, 2 and 3, and respectively shaft from the floor to the ceiling. Frames 4, 5 and 6 are provided, and these shaft frames 4, 5 and 6 also have a structure in which steel frames are incorporated as much as possible, like the frame assembly frames 1, 2 and 3.

The above-mentioned frame assembly frames 1, 2, 3 on each floor
And shaft frames 4, 5 and 6 corresponding to them respectively as one set / one floor, and a predetermined number of floors, for example, three floors in this embodiment, are vertically connected by a steel material such as shaped steel, One shaft unit is used. Next, a steel plate or the like is attached to each floor surface portion of the frame assembly frames 1, 2 and 3, and required pipes 7 such as pipes and ducts penetrate the steel plate and the like.

A skeleton alloy is attached to a portion of the skeleton other than the skeleton steel frame that is to be fitted to the skeleton. Further, as described above, the pipes 7 penetrating in the shaft unit are fixed to the shaft frames 4, 5 and 6 by metal fittings such as pipe bands according to the arrangement requirement, and the upper end is the top shaft. It is inside the frame 4, and the lower end thereof projects downward from the lower frame assembly frame 3.

Next, a base 8 such as a wall panel for finishing a shift space section of a building, or a finishing panel 9 assembled to the base 8 is attached to each shaft frame 4, 5, 6. Reference numeral 10 in the figure denotes a pipe frame which is the floor of the shaft unit. Further, in the figure, the range indicated by A on the uppermost floor shows the state of the frame only, and B on the intermediate floor. The range indicates the state up to the base 8, and the range indicated by C on the bottom floor indicates the state in which the finishing panel 9 is completed. Particularly, in this embodiment, the wall surface and the inside of the finishing panel 9 are
Depending on the required specifications, fittings such as doors and inspection ports 11, fire hydrants 12, and equipment such as a distribution board (not shown) are also attached.

In the shaft unit having the above construction, the frame steel frame is taken into the unit as much as possible, and other than that, the shaft unit is constituted by the minimum necessary frame.
By installing a base material or finishing material, the rigidity is increased and the waste of material is eliminated, and since the degree of perfection at the factory is improved, on-site work is reduced, and work quality and safety are also improved. improves.

It should be noted that in the above embodiment, 1 for every 3 floors.
Although the number of shaft units is one, the number of floors may be one unit for two or more floors, and the above shaft units are sequentially stacked and fixed in the shaft space of a high-rise building. By doing so, the shaft of a high-rise building can be constructed efficiently.

[0016]

According to the shaft unit of the present invention described above, waste of material can be eliminated by incorporating the core steel frame into the shaft structure, and each unit almost completed in the factory can be mounted on site. Therefore, it is possible to reduce on-site work, shorten the construction period, and improve safety and quality.

Further, the unit of the present invention has only the minimum necessary frame structure for fitting with each layer, and after the completion, an unnecessary frame structure is unnecessary, and it is possible to make a long shaft pipe unit having low rigidity. It will be possible.
