Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a ceiling wiring board for a housing unit that is arranged in a housing unit.

[Background technology]

In order to shorten the construction period, unit construction methods are being used frequently these days.

In this unit construction method, first, on the factory line,
A box-shaped frame is formed from columns and beams, and the outer walls are attached to this frame and interior work is done to manufacture the housing unit. During this interior construction work, joists are placed on the ceiling, and then various electrical wiring is installed along the joists.

A large number of various housing units are manufactured at the factory, and these housing units are transported to the site by truck. At this time, sheets are placed over the housing units placed on the truck bed, but in order to prevent damage to the housing units when workers climb on top of them, conventionally plate-shaped scaffolding was used to cover the joists of the housing units. It may be placed on top.

A large number of housing units transported to the site are placed on the foundation using a crane, with scaffolding placed on the top side. Thereafter, a worker climbs onto the scaffold and performs work to connect the plurality of housing units. After completion of a given task, the scaffolding is removed from the housing unit and taken back to the factory or disposed of on site.

[Problem to be solved by the invention]

The above-mentioned unit construction method is not rational because the unit assembly and ceiling wiring work are done on the same line.

Moreover, the ceiling wiring work can only be done after the joists have been installed, and in addition, the wiring work is troublesome because the electric wires must be run between multiple joists. Further, since the wiring is made up of a large number of intertwined electric wires, when the scaffolding flaps due to the shaking of the truck during transportation of the housing unit, the electric wires will rub against the scaffolding. Furthermore, when the unit is placed on the foundation by a crane, the electric wires may rub against the scaffolding. When electric wires rub, not only does on-site maintenance become troublesome, but it can also lead to electrical leakage accidents. Furthermore, the used scaffolding must be removed from the housing unit, which is also cumbersome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ceiling wiring base for a housing unit that can shorten and reliably perform ceiling wiring work and can also be used as a scaffold.

[Means to solve the problem]

The ceiling wiring board for a housing unit of the present invention is characterized in that electrical wiring is incorporated into a rigid plate-like member disposed on the upper surface side of the housing unit.

Here, the rigid plate-like member is made of a material such as wood, gypsum, or synthetic resin, and its strength is at least such that it will not be damaged even when a person rides on it.

[Effect]

In the present invention having such a configuration, a housing unit is manufactured in a factory by applying exterior and interior decoration to a frame made of beams and columns. Further, on a line different from this production line, a ceiling wiring board is manufactured by incorporating various electrical wiring into the rigid plate-like member. When the above construction is completed, a ceiling wiring board is placed on the upper side of the housing unit, and the housing unit is placed in this state on the loading platform of a truck. When covering this unit with a sheet, the ceiling wiring board is used as a scaffold.

The housing units are transported to the site by truck, but the electrical wiring is built into a rigid plate-like member, so even if the ceiling wiring base flutters due to the shaking of the truck, the electrical wiring will not be damaged.

Multiple housing units are transported to the site and then assembled on the foundation. This assembly is performed with the ceiling wiring board attached to the upper surface of the housing unit.

Note that the ceiling wiring board may be attached to the upper surface side of the housing unit on-site.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 shows the overall structure of the housing unit. In FIG. 1, lower beams 2 are installed between the lower ends of four pillars 1, and upper beams 3 are installed between the upper ends of each of the four columns 1 to form a frame 4. The upper beam 3 is formed to have a U-shaped cross section, and a plurality of joists 5 are attached between mutually opposing openings. Further, a plurality of wire insertion holes 3A are formed in the vertically extending side wall of the upper beam 3 so as to horizontally penetrate therethrough.

As shown in FIG. 2, a ceiling plate 6 is attached to the lower surface of the upper beam 3. This ceiling plate 6 has a circular electric wire insertion hole 6A vertically penetratingly formed in the center thereof, and an oblong electric wire insertion hole 6B formed at the end.

A ceiling wiring board 7 for a residential unit according to this embodiment is arranged on the upper surface of the joist 5. This ceiling wiring board 7 includes a rigid plate-like member 8 made of gypsum board, and this rigid plate-like member 8 has at least enough strength to not be damaged even when a person rides on it. A horizontally extending groove 8A is formed at the bottom of the rigid plate-like member 8, and various electric wirings 9 are arranged in this groove 8A. These electrical wiring 9 are as shown in FIG. 3 where the bottom of the ceiling wiring board 7 is shown.
One end is exposed from the bottom of the end of the rigid plate-like member 8 and is inserted into the oval wire insertion hole 6B of the ceiling plate 6, and a part of the other end is exposed from the bottom of the end of the rigid plate-like member 8. The remaining end is exposed from the side surface of the rigid plate-like member 8 and inserted into the wire insertion hole 3A of the upper beam 3, and the rest of the other end is exposed from the lower surface of the rigid plate-like member 8 and inserted into the wire insertion hole 6A of the ceiling plate 6. It is designed to be inserted.

Further, a plate-shaped cover 10 is attached to the rigid plate-shaped member 8 to prevent the electric wiring 9 from falling, and a cushioning material 11 such as a sponge is interposed between the cover 10 and the electric wiring 9. ing.

To construct a house using a housing unit having such a configuration, first, the housing unit is manufactured at a factory. Therefore, the frame 4 is assembled by assembling the column 1, lower beam 2, and upper beam 3.
A frame 4 is made, and an exterior wall, an interior wall, etc. are attached to this frame 4. Furthermore, a plurality of joists 5 are attached between the upper beams 3, and a ceiling board 6 is attached to the lower surface of the upper beams 3.

In parallel with the above-mentioned work, the ceiling wiring board 7 for housing units is manufactured on a separate line. That is, the groove 8A of the rigid plate member 8
Various electric wirings 9 are placed in the area, and a lid material 10 is attached.

After completing these operations, the ceiling wiring board 7 is placed on the upper surface of the joists 5, and the housing unit is placed in this state on the loading platform of a truck. When covering this unit with a sheet, the ceiling wiring board 7 is used as a scaffold.

Multiple housing units are transported to the site and assembled on foundations (not shown). This assembly is performed with the ceiling wiring board 7 placed on the upper surface of the joists 5. The worker rides on the ceiling wiring board 7 and performs the work of connecting adjacent housing units. Further, the electric wiring 9 has one end connected to a power source, a part of the other end connected to a lighting fixture (not shown), and the rest of the other end connected to the electric wiring of a housing unit located next to it.

According to this embodiment, the ceiling wiring board 7 for a housing unit is manufactured by incorporating the electrical wiring 9 into the rigid plate member 8, and the ceiling wiring board 7 is placed on the upper side of the housing unit. The wiring work can be done without waiting for the installation of the joist 5 to the upper beam 3, and the wiring work on the ceiling, and by extension,
Manufacturing time for housing units can be reduced. Also, it is rational because wiring work can be done on a separate line from the unit manufacturing line. Moreover, since there is no need to run the electrical wiring 9 between the plurality of joists 5, the wiring work is simple. Moreover, even if the ceiling wiring base 7 flutters due to the shaking of the truck when transporting the housing unit to the site by truck, or the ceiling wiring base 7 rubs against the joists 5 when the housing unit is suspended by a crane. However, the electrical wiring 9 is not damaged. Therefore, on-site maintenance of the electrical wiring 9 is not required, and electrical leakage accidents do not occur. Moreover, the ceiling wiring board 7 can also be used as a scaffold. Therefore, there is no need to prepare a separate scaffold, and furthermore, the conventional work of removing a used scaffold can be omitted.

In addition, in the above embodiment, the ceiling wiring board 7 for residential unit
is arranged on the upper surface of the joist 5, but the ceiling wiring board 7 may be arranged on the upper surface of the upper beam 3.

Further, in the present invention, the manufacturing process of the ceiling wiring board 7 and the assembling process of the housing unit may be performed in separate factories, and the board 7 may be assembled into the unit on site.

Furthermore, the material of the rigid plate-like member 8 is not limited to plaster, and may be synthetic resin such as acrylic or wood. In short, the rigid plate-like member 8 must have at least a strength that will not be damaged even when a person rides on it. Bye.

If synthetic resin is used as the material for the rigid plate-like member 8, the electrical wiring 9 can be incorporated inside the rigid plate-like member 8 and the ceiling wiring base 7 can be integrally molded, and the cover member 11 can be omitted.
