Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a building unit that can be assembled into a unit building.

[0002]

2. Description of the Related Art In a unit building, a box-shaped unit having a certain size that can be transported, and finished interior and exterior building units are produced in advance in a factory, and a plurality of these building units are transported to a construction site. However, it is a building that is assembled at the construction site. This unit building has a short on-site construction period,
In addition, because of the characteristic that it becomes a standardized building with good dimensional accuracy, many buildings have been built in recent years.

Many types of building units have been known as building units that can be assembled into this unit building, but a plurality of vertically installed columns and a floor structure attached to the lower ends of the plurality of columns are known. Many building units include a body and a ceiling structure attached to the upper ends of a plurality of columns.

[0004] For example, in Japanese Utility Model Laid-Open No. 1-25134, a ceiling structure has a plurality of ceiling rims, a first fire plate attached to the lower surface of the ceiling rim, and an upper surface of the ceiling rim. A building unit consisting of a second fire plate attached to the. The unit building in which this building unit is assembled has the following features.

That is, when a fire occurs on the lower floor, the flame first reaches the ceiling and spreads from the ceiling to the upper floor and the next room. In this unit building, first, the flame spreads from the ceiling to the upper floor. Even if the first fire plate is prevented from spreading to the next room by the first fire plate and then the first fire plate is destroyed by the flame,
It can be prevented with a fire plate. Therefore, even if a fire occurs, this unit building can significantly delay the spread of fire to the upper floors and the adjacent rooms, and is extremely fire-proof.

In Japanese Patent Laid-Open No. 2000-291153, a ceiling structure is attached to a plurality of ceiling rims, a ceiling surface material attached to the lower surface of the ceiling rim, and an upper surface of the ceiling rim. A building unit is described in which a scaffolding board and a top surface of the scaffolding board are substantially at the same height as the upper end of the pillar. This building unit has the following features.

That is, the building unit is manufactured in a factory, stored, and then transported to a construction site. At this time, during the storage period or during shipping, it rains and gets wet, or dust or the like adheres to it and contaminates it. To prevent this, the building unit is usually covered with a protective sheet. At this time, if the ceiling structure is lower than the upper ends of the columns, a depression is formed on the upper surface of the protective sheet. When it rains on the protective sheet, rainwater accumulates in the depressions on the upper surface of the protective sheet, and the weight of the rainwater makes the depressions larger, and a larger amount of rainwater accumulates in the enlarged depressions. However, a large amount of rainwater gradually accumulates, and in the end, there is a problem that the weight of the rainwater may damage the ceiling surface material or the protective sheet may tear. Therefore, it was necessary to remove this rainwater, which was extremely inconvenient.

However, in the above-mentioned building unit, since the upper surface of the scaffolding plate has substantially the same height as the upper ends of the columns, there is no depression on the upper surface of the protective sheet. Therefore, in this building unit, rain does not collect rainwater on the protective sheet, and the above problem does not occur. Also, when this building unit is assembled into a unit building at a construction site, it can be placed on a scaffolding board for work. In this way, rainwater does not collect on the protective sheet, and because it can be mounted on the scaffolding plate for assembly work, it is a very convenient building unit.

Further, in Japanese Unexamined Patent Publication No. 9-65552, a joint box and a conductor wire connected to the joint box are installed on the upper surface side of a ceiling panel of a building unit, and the end portion of the conductor wire is flexible. A lead-in wire is connected, this lead-in wire is temporarily fixed to the lead-in opening provided on the peripheral edge of the ceiling panel, and the wiring pipe that opens near the lead-in opening at the parting portion where the inner wall material and ceiling panel intersect It describes an in-building wiring structure that is provided on the outside of the inner wall material and has a lead-out portion formed under the wiring pipe.

In this building unit, after installation, a person who is inside the room puts his / her hand through the lead-in opening to remove the temporary fixing of the flexible lead-in wire, and then the lead-in wire is inserted through the opening of the wiring pipe into the wiring pipe. The conducting wire is laid out on the outside of the inner wall material (that is, inside the wall) in such a manner that it is lowered and taken out from the outlet and connected to, for example, an outlet.

[0011]

However, the above-mentioned Japanese Patent Laid-Open No. 20
The building unit described in Japanese Patent Publication No. 00-291153 has the following problems. That is, in general, a building having a wider space between the floor and the ceiling has better habitability, but the height of building units constituting a unit building is limited due to transportation by a truck or the like. Therefore, in the building unit, the floor structure is attached to the lowest possible position of the pillar, and the ceiling structure is attached to the highest possible position of the pillar.

In a two-story unit building in which a building unit (upper floor building unit) is installed on such a building unit (lower floor building unit), the ceiling structure of the lower floor building unit and the upper floor The space between the floor structure of the building unit is narrow. And in the building, it is necessary to wire the conductors in order to use the electric appliances, but after installing the building unit, between the ceiling structure of the building unit on the lower floor and the floor structure of the building unit on the upper floor. In addition, when trying to wire the conductor, the space between the ceiling structure and the floor structure is extremely narrow and it is difficult to wire.

For this reason, when the building unit is manufactured, it is convenient to wire the conductors in the factory in advance and to install the building unit with the conductors, because it is not necessary to wire the conductors. So, when I tried wiring on the ceiling structure of the building unit on the lower floor, that is, on the scaffolding board, when installing the building unit, I caught my foot on this conductor and the worker rolled around. , The conductor may be cut.

Further, in the building unit described in Japanese Utility Model Laid-Open No. 1-25134, the second fireproof plate on the upper side is lower than the upper ends of the columns. The fireproof plate used here usually has low mechanical strength.

Therefore, when the building unit is covered with a protective sheet and rains when it is stored or transported, and rainwater accumulates on the upper surface of the protective sheet, the second fire prevention plate causes the weight of the accumulated rainwater to accumulate. Since it is not possible to perform work on the second fire plate when it is damaged by or when installing the building unit, conventionally, above this second fire plate, at approximately the same height as the top of the pillar, After temporarily placing a scaffolding board with high mechanical strength, cover the building unit with a protective sheet so that the second fire prevention board will not be damaged even if it rains,
When the building unit was assembled into a unit building, it was placed on this temporarily placed scaffolding board to work, and when the work was completed, this temporarily placed scaffolding board was removed.

Thus, this utility model model 1-2513
The building unit described in Japanese Patent No. 4 was inconvenient because a scaffolding board was required. In addition, when wiring was done at the factory on the second fireproof plate of this building unit, when the building unit was assembled into a unit building and then the temporarily placed scaffolding plate was removed, this scaffolding plate was hooked on the conducting wire Turned out to be a problem.

The in-building wiring structure described in the above-mentioned Japanese Patent Laid-Open No. 9-65552 is extremely convenient because it is pre-wired in the building unit, but it is said that the conductor wire is wired on the upper surface of the ceiling panel. However, there is the above-mentioned problem, that is, the worker hooks the conductor on the lead wire or the scaffolding board gets caught on the lead wire when assembling, and after installation, the person in the room puts his hand through the small inlet. , Work to remove the temporary stop of the flexible lead-in wire and lower this lead-in wire from the opening of the wiring pipe to the inside of the wiring panel,
It is extremely difficult and troublesome to take out the conductor that has gone down in the wiring panel from the narrow outlet.

Therefore, an object of the present invention is that wiring can be easily made in a ceiling structure or a wall panel, and even if a conductor is wired in a factory, a worker can put it on the conductor during installation. It is an object of the present invention to provide a building unit in which a scaffolding board is not hooked on a conducting wire when the scaffolding board is hung on or a temporary scaffolding board is removed.

[0019]

The present invention has been made to achieve the above object, and the invention according to claim 1 is to provide a plurality of upright columns and lower end portions of the plurality of columns. A building unit consisting of a floor structure attached to a ceiling and a ceiling structure attached to the upper ends of a plurality of pillars, wherein the ceiling structure includes a plurality of ceiling fields and a lower surface of the ceiling field. A lower ceiling panel, an upper ceiling panel attached to the upper surface of the ceiling edge, and a conductor wire provided between the lower ceiling panel and the upper ceiling panel.

The invention according to claim 2 relates to the invention according to claim 1, wherein the upper ceiling surface material of the ceiling structure is a scaffold plate attached with its upper surface at substantially the same height as the upper ends of the pillars. There is something.

There is a ceiling rim.

Therefore, the conductor wire that is laid between the lower ceiling surface material and the upper ceiling surface material is between a plurality of ceiling margins, and the ceiling margin is a tubular body or a long body having a U-shaped cross section. Then, in the tubular body, in the U-shaped cross section, or when the ceiling edge is provided inside the edges of the lower ceiling surface material and the upper ceiling surface material, outside the ceiling field edge. That is, it means a conductor wire that is laid between the lower ceiling surface material and the upper side surface material.

Further, when it is necessary to wire the conductor across the ceiling edge, a through hole or a notch is provided in the ceiling edge,
Wiring may be performed through the through hole or the notch, or when the conductor is thin, wiring may be performed between the ceiling edge and the lower ceiling surface material or the upper ceiling surface material. The ceiling edge described in the invention of claim 1 or the invention of claim 4 is formed by molding an appropriate material into a field shape. For example, it may be a quadrangular bar-shaped wood, a metal tubular body having a square cross-section, or a long metal body having a square cross-section.

According to the fourth aspect of the present invention, the wall panel is erected between the floor structure and the ceiling structure, but the wall panel may be a partition wall panel for partitioning a room. It may be a wall panel provided outside the building.
And, the conductor wire wired between the lower ceiling surface material and the upper ceiling surface material is extended in this wall panel, but the conductor wire extended in this wall panel is a wall panel. It may be a lead wire that leads to a building unit on the lower floor therethrough or a lead wire that connects to an outlet attached to the wall material of the wall panel. In the case of a lead wire connected to an outlet mounted on a wall, it is preferable to provide an outlet on the wall panel at the factory and connect the lead wire to this outlet because wiring work at the construction site is reduced.

A building unit comprising a structure, wherein the ceiling structure has a plurality of ceiling rims, a lower ceiling panel attached to the lower surface of the ceiling rim, and an upper surface of the ceiling rim. Since the ceiling structure is composed of the upper ceiling surface material and the conductor wire that is provided between the lower ceiling surface material and the upper ceiling surface material, the conductor wire is already attached to the ceiling structure.

That is, when the building unit is manufactured in the factory, the conductor wire can be installed between the plurality of ceiling rims. Therefore, it is easy to wire the conductor to the building unit, and after installing the building unit at the construction site, wire the conductor between the ceiling structure of the narrow lower floor building unit and the floor structure of the upper floor building unit. There is no need, wiring at the construction site is easy, and the number of wiring steps is reduced.

Further, as described in Japanese Patent Laid-Open No. 2000-291153, when the upper ceiling panel is a scaffolding board, the conductor wire is wired between the lower ceiling panel and the upper ceiling panel. Therefore, it does not appear on the surface of the ceiling structure, that is, the upper surface of the scaffold plate. Therefore, when installing the building unit, the building unit can be installed with peace of mind without getting caught in the conducting wire. Also, utility model 1-2
As in Japanese Patent No. 5134, when the upper ceiling panel is lower than the upper ends of the pillars and the scaffolding board is temporarily placed above the upper ceiling panel, the scaffolding board is hooked to the conductor when removing the temporarily placed scaffolding board. It can be removed without any worry.

According to the second aspect of the present invention, since the upper ceiling panel of the ceiling structure is a scaffolding plate attached with its upper surface at substantially the same height as the upper ends of the columns, the building unit is covered with a protective sheet. Rainwater does not collect on the upper surface of the protective sheet even if it rains when stored or transported, and therefore the upper ceiling surface material is not damaged by the rainwater accumulated on the upper surface of this protective sheet, and the protective sheet breaks.
