DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping unit used for piping for supplying water or hot water in a house and a piping method using the same.

[0002]

2. Description of the Related Art For example, in the case of an apartment house composed of a large number of dwelling units, it is difficult to secure skilled workers. There has been a strong demand for systematization in such a direction that work can be carried out in a targeted manner. In view of the piping work in the water supply and hot water supply systems from such a viewpoint, there are still many insufficient points.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a piping unit which can greatly advance the systemization required for an apartment house with regard to the piping work of water supply and hot water supply systems. Another object of the present invention is to provide a piping method using such a piping unit.

[0004]

For this purpose, the present invention presupposes that piping for water supply or hot water supply is performed through a ceiling or a floor, and a piping unit for that purpose is provided with a header. A plurality of pipe members which are communicated with each other via the header, and each pipe member is preliminarily adjusted to a length at which a tip end reaches a target pipe end, and a pipe end is formed. A bend index indicating a bend position and a bend direction in any of the left, right, up, and down directions is attached to a portion to be bent in between.

[0005] When such a piping unit is constructed through a ceiling, a header is fixed to a predetermined position of the ceiling, and then each pipe member is attached to a bending index attached thereto. It is constructed so that the tip of each pipe member reaches the end of the target pipe by sequentially fixing it to the ceiling while bending it at a right angle based on the position and direction based on the advanced system Is possible.

That is, according to the above-described piping unit and the piping method therefor, after fixing the header at a predetermined position, it is extremely simple to bend each pipe member at a right angle based on the bending index. The piping for the required section can be performed by a simple operation. As a result, necessary work is simplified, and troublesome work such as collation with a design drawing or a construction drawing is not required. For example, even a non-skilled person can easily and efficiently perform a flow work. As a work content, a high degree of systematization is achieved.

[0007] The display of the bending direction in the bending index of the piping unit as described above can be in various forms. However, if the color is given to the bending index, it is easy to see and mistakes are prevented. It is particularly preferable because it is easy.

In the piping method using the piping unit as described above, a plurality of rail members attached to the ceiling slab surface at regular intervals in parallel with each other so as to be inclined with respect to the side of the ceiling slab. A supporting means comprising a plurality of supporting members slidably engaged in the longitudinal direction of the rail member in the engaging grooves of these rail members, and each of the supporting members is arranged to be parallel to the side of the ceiling slab. If the pipe members are passed through and the support members support the respective pipe members at the intersections between the respective pipe members and the respective rail members, an even more sophisticated system can be achieved.

In other words, according to this method, the pipe member parallel to the side of the ceiling slab always has several intersections at regular intervals with the rail member inclined to the side of the ceiling slab. Therefore, by supporting with a support member positioned at the intersection, uniform support can be performed efficiently and without the need for cumbersome work such as blackout.

Embodiments of the present invention will be described below. This embodiment is an example in which a common trunk line for each dwelling unit and a meter box in which a meter for each dwelling unit is provided for electricity, gas, water, etc. are installed in a multi-dwelling house of a type in which two dwelling units are provided. As shown in the plan view and the schematic diagram of FIG.
Piping units 1 and 2 are used for the water supply system and the hot water supply system, respectively, and piping is performed from the ceiling to the required section.

The two pipe units 1 and 2 are provided with a required number of branch pipe members 12 and 12 for one main pipe member 11 and 21.
, ..., 22, 22, ... are connected via headers 10, 20. These piping units 1, 2
FIG. 3 shows a typical example of the piping unit 1 as a representative example. In this embodiment, the piping unit 2 is different from the piping unit 1 only in the number of branch pipe members, and the other structures are the same as those of the piping unit 1.

As shown in FIG. 3, the header 10 of the piping unit 1 is provided with a fixing plate P for fixing to a ceiling slab on a tubular header body 10m provided with a plurality of connection ports 10s, 10s,. The main pipe member 11 and the branch pipe members 12, 12,... Are connected to each other by being connected to the connection ports 10s, 10s,.

The main pipe member 11 and the branch pipe member 1
Each of 2, 12,... Is composed of plastic sheath tubes 11s, 12s and core tubes 11c, 12c. Bending index T of the given color,
T,... Are attached using a tape-shaped material.

The piping units 1 and 2 are constructed as follows. First, the headers 10 and 20 are fixed to the ceiling slab via the fixing plate P in a predetermined position and orientation as shown in the figure, or are fixed using a support member 18 provided as described later. Then, parent pipe members 11, 21 and branch pipe members 12, 12, ..., 2
The bending index T assigned to each of 2, 22,...
In the position of T,... Always bend at a right angle in the direction according to the bending direction indicated by the bending index T, T,. Sequentially fixed to the ceiling slab. Then, the respective ends are naturally the target pipe ends, that is, the main water supply trunk line W in the meter box M in the parent pipe member 11,
In the main pipe member 21, the water heater U in the meter box M, and in the branch pipe members 12, 12, ..., 22, 22, ... water supply in the bathroom X, the toilet R, the washing / washing place Y, and the kitchen K. Since the water reaches the water inlet and the hot water supply port, the necessary connection work is performed at the end of the pipe to complete the operation.

Each of the pipe members 11, 21, 12, 12,...
The fixing of 22, 22,... To the ceiling slab is performed using a support means provided in advance on the ceiling slab S as shown in FIG. Specifically, the support means is, for example, 640 mm
A plurality of rail members 16, 1 attached to the lower surface L of the ceiling slab S in a pattern that is parallel to each other at a constant interval and is oblique to the side of the ceiling slab S as shown in FIG. 5.

Slidably engaged with and supported by engagement grooves 17 formed in the respective rail members 16 in the longitudinal direction. .., Or at appropriate intervals, and the above-mentioned tube members are held by the support member 18 located there.

When the pipes are constructed in this manner, they are constructed, for example, in the order of zones shown in FIG. Specifically, from the lower surface L of the ceiling slab S to the ceiling ground S
Toward S, in order, the rail members 16, 16,
.., A wiring zone B for electric wiring, a piping zone C for the above-mentioned piping unit, and a duct zone D for a ventilation duct, and B → C → Work in the order of D. That is, since the construction work of the pipe and the duct is performed by the same operator, the construction of the pipe and the duct can be continuously and integrally performed in this manner, which is convenient. In addition, workability is good because the pipe and the wiring do not cross.

On the other hand, the fall of the parent pipe members 11, 21 to the meter box M is performed as shown in FIG. That is, the meter box M is bent downward at a position where it comes into contact with the partition wall Mw on the rear surface, and further bent outward at the through holes Mh and Mh provided in the partition wall Mw so that the leading end portion is guided into the meter box M. I have.
