Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to piping and wiring ducts in electrical equipment and a method of constructing the same.

[0002]

2. Description of the Related Art In electrical equipment, there is a building work. In the building work, there are pipes and wirings. In the pipe work, slab pipes (pipes in soil concrete) and pipes in ceilings are independently performed.

[0003] In addition, wiring is also separately wired in the ceiling floor for high and low currents, and workers also perform high and low current construction separately.

[0004] By the way, if a design change or forgetting of the construction occurs after the construction is performed, the reworking operation requires a lot of man-hours and increases the cost.

[0005] Slab piping (soil-to-soil concrete piping) has problems with crossing of piping and piping with a large piping diameter has a problem in slab strength. For example, there is a defect such as a crack.

A slab piping process is included in the construction process.
After arranging the reinforcing bars, perform slab piping.

Buildings have fire-resistant compartments for fire-fighting, and must be treated for fire resistance when piping and wiring are passed through the compartments.
At present, the penetration of the compartment is not one,
Wiring penetrates.

[0008]

However, such a conventional construction has the following problems. 1. There was a problem that the cost was high because separate contractors were working independently on the construction of high and low currents. 2. Slab pipes, that is, pipes in concrete, have concrete in the pipes or have broken pipes due to anchors and the like, making repairs difficult and time-consuming. 3. If additional changes or forgotten work occur, it is very difficult to add, because it is a single pipe and wiring. 4. Soil concrete is generally 120mm-200m
It is generally cast with a thickness of m, and reinforcing steel is generally arranged in the concrete doubly, and piping is provided between the reinforcing steel and the reinforcing steel. Therefore, the concrete strength is reduced due to the intersection of the pipes, such as an increase in the pipe diameter. 5. Since there is a lot of on-site processing due to single piping and wiring, lapping work is frequent, and the construction site is crowded with personnel, materials, tools and the like. 6. Since electric facilities such as wiring, piping, strong electricity, weak electricity, etc. are performed independently, maintenance and inspection are difficult and cost is high.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to provide a duct unit capable of improving workability.
It is another object of the present invention to provide a duct unit that can easily cope with additions, changes, and forgotten works. Also,
The purpose is to provide a duct unit that can be easily maintained and inspected.

[0010]

According to a first aspect of the present invention, there is provided a duct in which piping and wiring from a distribution board to a distribution board and from a distribution board to high- and low-power devices are assembled in a duct unit. Unit. In addition, the dimensions, shape, arrangement,
The material is not limited.

According to the second aspect of the present invention, the connection between the duct units is performed by one-touch connection of the pipe call line rails inside the connection between the duct units, and the connection method is not limited.

According to a third aspect of the present invention, there is provided a rail mainly used for passing electric wires in a duct space other than a piping space. The dimensions and shape of the rail are not limited.

According to a fourth aspect of the present invention, there is provided a duct unit capable of taking out branch piping and wiring from a junction box duct. The take-out position is not limited.

According to a fifth aspect of the present invention, a function is provided in which a strong electric current and a weak electric current are gathered, and a branching function is provided from the middle, so that a factory can be manufactured. Is a duct unit.

According to the sixth aspect of the present invention, the use of the duct unit facilitates maintenance and inspection checks and improves work efficiency. This is because the duct unit is provided with a function in which a branch is formed in the middle of the duct, and the connection line between the connection boxes easily exits by changing the call line.

[0016]

According to the present invention, if the duct unit is connected, a high-current pipe and a low-current pipe and a wiring path can be secured. Further, since the wiring is also provided with the call line rail, the number of wirings is not limited as long as it is within an allowable amount after the duct unit is mounted. That is, even if addition or change is made, a wire can be formed in the duct later, so that workability can be improved.

According to the fourth aspect of the present invention, a function of branching from the middle of the collecting duct is provided, so that piping and wiring can be drawn from anywhere.

According to the fifth aspect of the present invention, since a refractory material is used, and the duct connection box, the branch portion, and the like are sealed and have a fire-resistant structure, compared with the conventional method, a fire-resistant material is used. Long wire protection. Further, in the construction method in the fireproof compartment, conventionally, for example, the fireproof wall was pierced independently when penetrating. However, according to the invention of claim 6, since there is a collective duct, the number of penetrating portions is small.
