Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] When piping for a building or the like, the present invention accommodates a pipe and its associated pipes and ancillary equipment in a frame in which a long shape member is arranged on a ridge line portion. The present invention relates to a building piping unit and a piping prefabricated construction method in which piping is constructed by mounting the frame on a building frame.

[Conventional technology]

As a conventional pipe for a building, for example, as shown in FIG. 11, vertical pipes 1 vertically penetrating the building are centrally arranged in a pipe space section in the building. Then, in the conventional building piping construction method, the piping through hole 3 is constructed on the floor 2 at the time of construction of the building frame. Next, pipe materials, joints, pipe support fittings, and pipeworking machines are brought in, the pipes 1 are measured one by one at the site, and after the pipes are cut and threaded, the pipe joints are connected and welded at the site to connect the pipes. At the same time, the pipe 1 is installed and fixed to the body of the building by the support fitting 4. Further, the piping work is performed by backfilling the gap between the pipe 1 and the through hole 3 with a refractory material such as concrete. Since this backfilling work must be done without gaps from above and below by sandwiching the floor of the floor, it is difficult to carry out, and sufficient care must be taken. In the example of sanitary piping shown in FIG. 11, the drainage pipe 5 is provided with a cleaning port 5a and a collecting pipe 6, a branch pipe 7 branches from the collecting pipe 6, and a plurality of drainage pipes 5 are connected to each floor. The branch pipes 7 can be assembled. Longitudinal water supply main pipe in the water supply piping system
A branch pipe 7a branches from 6a, and the branch pipe 7a is equipped with auxiliary equipment such as a valve 7b and a water meter 7c. The hot water supply piping system has the same configuration as above. Further, the respective pipes are connected by various pipe joints 8 and welded by the on-site welded portion 9. In addition to this, air conditioning piping and fire extinguishing piping may be provided. Insulation work may be performed on sanitary piping and air-conditioning piping, but generally, after the piping work is completed in the building, the insulation work that winds the heat insulating material is performed, and finally the painting work is performed. It was

[Problems to be Solved by the Invention]

By the way, in such a conventional method for constructing pipes in a building, pipes, pipe fittings, and pipeworking machines are brought into the building, and pipes are constructed one by one while performing measurement, cutting, thread cutting, etc. However, such a conventional construction method has a problem that the work efficiency is poor because it is performed in a dangerous construction site, a lot of construction steps and man-hours are required, and a construction period is long. This is a big problem especially in the case of high-rise buildings, but it is also required to have fire safety, earthquake resistance, heat expansion and contraction measures for pipes due to the temperature difference between the fluid in the pipes and the building frame, and vibration and soundproofing. Since durability is also required, it is extremely difficult to satisfy all of these technical requirements.

In addition, in order to reduce the number of steps when installing pipes in buildings such as buildings, it is preferable to install pipes that are as long as possible without cutting them, and if the pipes for the second floor are 6-8.
If the length of the pipe is 3 m, the length will be 9 to 12 m, but if the pipe becomes long, the rigidity will be insufficient and it will bend, and if it is lifted during installation, it will buckle. Furthermore, after all the equipment and equipment are connected as a piping system, a pressure resistance and airtightness test is performed,
If a leak is detected, it must be repaired, but there are problems that the number of connection points in the field is so large that it takes a lot of man-hours for inspection and the leak probability is high.

The present invention has been made by paying attention to such conventional problems. Most of the piping construction conventionally performed at the construction site has been made into a factory, and technically high demands have been made in the factory. It is an object of the present invention to provide a piping unit for a building and a piping prefabricated construction method that can satisfy the requirements and can install the piping at an accurate position in the building by performing a simple construction on site.

[Means for Solving the Problems]

The present invention, as a means for solving the above-mentioned problems, has a structure in which a profile having a length that vertically penetrates one or more floors of a building is arranged on a ridge, and a plurality of pipes are provided inside. A building piping unit is formed so as to have a housed frame and a plate body that is mounted at a position corresponding to the floor of each floor of the frame and has a hole through which the plurality of pipes penetrate, and also forms a building piping unit. A plate body in which a plurality of pipes are housed inside a frame in which a profile having a length that vertically penetrates one or more floors is arranged in a ridge portion, and which is mounted at a position corresponding to the floor of each floor of the frame Piping for a building is performed by installing a piping unit formed by penetrating the plurality of pipes in a through hole provided in the building on the frame of the building.

[Action]

Next, the operation of the present invention will be described. A long frame is placed on the ridge, and a frame having a length that vertically penetrates one or more floors of the building is provided, and a plurality of pipes are housed inside the frame. And since the building piping unit having a plate body having a hole through which the plurality of pipes penetrate is installed at a position corresponding to the floor of each floor of the frame, by providing this plate body, Not only does the piping unit have a rigid function due to the frame, but the strength of the piping itself is also combined to form a piping unit that has excellent strength and rigidity. The piping units thus formed are sequentially installed on the frame of the building, and at the site, only the installed piping is joined to perform piping inside the building.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, showing a sanitary piping unit. The pipe unit 30 has four pipes 11 such as a drain pipe, a water supply pipe, and a hot water supply pipe.
12, the cleaning port 13, the valve 14, the collecting pipe 16 and the like are housed in a frame 15 in which angle members are arranged on the ridgelines on all sides. In addition, the pipe 11 includes a drainage pipe 17, a water supply pipe 18, and a hot water supply pipe.
There are 19 etc., each of which has a drain branch pipe 17a, a water supply branch pipe 18a,
Ancillary pipes such as the hot water supply branch pipe 19a are connected.

As shown in FIG. 2, a band 21 is attached to the pipe 11, a spring support 22 is attached to the band 21, and is attached to a horizontal beam 24 fixed to the frame 15 via a spring 23. Also, as shown in FIG. 3, there is also one in which a band 21a is attached to the pipe 11 and a vibration isolation support 22a is attached to the band 21a so that it can be attached to the horizontal beam 24 via a vibration isolation rubber 23a. In this way
The pipe 11 is not directly fixed to the frame 15 but is elastically supported by the cross beam 24 of the frame 15, which not only relaxes the thermal stress acting on the pipe in response to expansion and contraction of the pipe, but also the pipe.
The longitudinal vibration of 11 will be blocked from directly propagating to the building skeleton, and will also serve as a vibration and soundproof effect.

A plate 26 having a plane parallel to the floor is attached to a position corresponding to the floor 25 of each floor of the frame 15, and a through hole 27 through which the four pipes 11 are passed is formed in the plate 26. There is. That is, the piping unit 30 includes four large and small pipes in the frame 15.
The plate 26, which houses 11 and is provided at a position corresponding to the floor 25 of each floor, is attached in a state of penetrating through a through hole 27 through which the pipe 11 penetrates. In this way, the frame 15 and the plate body 26 are combined, and the pipe 11 is inserted into the through hole 27 of the plate body 25,
By combining the strength of the piping 11 and the rigidity of the frame 15, the piping unit 30 having excellent strength and rigidity is completed.

Here, the pipe 11 and the plate body 26 are not completely fixed, but have flexibility of ± 5 to ± 10 mm in the vertical direction and flexibility of ± 5 mm in the horizontal direction. There is. As a result, even if there is a slight construction error in the vertical direction and the horizontal direction, this error can be absorbed and the pipes 11 can be accurately and closely connected to each other. However, even if the space between the pipe 11 and the plate body 26 is not fixed in this way, as will be described later, when the pipe unit 30 to which the plate body 26 is mounted is lifted, the pipe 11 bends, 11 sides are plate 26
Since the inner surfaces of the through holes 27 of are not moved relative to each other, the plate body 26 and the pipe 11 are the same as being fixed in the sense that the pipe unit 30 is given strength and rigidity at the same time. Will have a great effect.

In addition, the plate 26 is divided into two parts at the through hole 27 and piping
A sleeve 28 may be formed at a portion of the through hole 27 of the plate body 26 through which the pipe 11 penetrates so that the sleeve 11 can be conveniently attached. The role of the sleeve 28 is that the pipe 11 thermally expands or contracts depending on the temperature of the fluid flowing inside, so that the pipe can be moved in the vertical direction correspondingly, and the pipe can be laterally moved due to an earthquake or other causes. When the vibrator 28 vibrates in the direction, the vibration is received by the sleeve 28 to suppress the amplitude. Further, a cushioning material 29 may be interposed between the sleeve 28 and the pipe 11 for the pipe requiring heat insulation or vibration isolation. For the cushioning material 29, an elastic material having a heat insulating property, non-combustible and having compressive strength is used. FIG. 4 shows a cross section passing through the center of the through hole 27 in a state where the sleeve 28 and the cushioning material 29 are mounted on the plate body 26.
As a result, not only the piping has a heat insulating effect, but also the lateral vibration of the piping is blocked from propagating to the building frame, and vibration and sound insulating effects are also achieved.

Here, the plate member 26 is generally provided at the floor position of each floor. When the plate member 26 is made of metal, the piping unit 30 is installed in the building and then a refractory material such as concrete is placed. Therefore, in the floor of the building, the pipe penetration portion also forms a fireproof structure to ensure fire safety and at the same time increase the seismic resistance of the pipe, which also improves soundproofing and vibrationproofing.

In the above embodiment, the case where four pipes are housed in the frame has been described, but any number of pipes may be used as long as the pipes are plural. In addition, the frame was constructed by arranging the angles on the four ridges, but if it is a long shape material, lightweight shape steel and other shape materials may be used, and the shape material should be three triangular shapes or four shape materials. It may be polygonal as described above. In addition, a band 21 is attached to the pipe 11, a spring support 22 is attached to the band 21, and the band 21a is attached to the horizontal beam 24 attached to the frame 15 via the spring 23. Is attached to the band 21a, and the vibration isolation support 22a is attached to the band 21a.
Although the one fixed to 24 has been described, another elastic supporting method may be used, and the pipe 11 may be directly fixed to the frame 15 when elastic support is not required.

Further, the plate body 26 facilitates the assembly of the piping unit,
Although the pipe 11 is divided into two parts at the through hole 27 as described above, the pipe 11 may be divided into two or more parts depending on the arrangement of the pipe 11. The water meter 12, the cleaning port 13, the valve 14, the auxiliary equipment other than the collecting pipe 16 in the piping unit 30 may be stored, and the auxiliary equipment may not be stored in the frame.
Other than the branch pipe 17a and the like may be provided as ancillary piping in the piping unit 30, and the ancillary piping may not be provided. Further, although the above-mentioned embodiment has described the sanitary piping unit, it may be applied to an air conditioning piping unit, a fire extinguishing piping unit, etc., and these can be configured to have the same configuration.

That is, the present invention, in order to minimize the site construction,
In the space of the piping unit 30, auxiliary equipment and auxiliary piping are installed in the longitudinal piping, installation of the pipe support mechanism, floor penetration mechanism, painting work, heat insulation construction, and as described later, completion up to the test To form the pipe unit.

Such a prefabricated piping method for a building using the piping unit 30, after manufacturing and assembling the piping unit 30 in the factory in advance, the piping unit 30 is transported to the place of the building and installed and joined to the building body 40 of the building. Let's do it.

When manufacturing a piping unit in a factory, a frame, a plate, a support metal fitting, and the like are manufactured in parallel with the manufacturing of the piping, and then the assembly of the piping unit is started. In order to facilitate the work of the assembly, the work is performed by horizontally placing it on the floor of the factory as shown in FIG. In addition, in order to make it convenient to assemble the piping unit and install it on the construction site, connect the frame 15 of the profile with the length of multiple floors of the building to the piping unit 30
On both sides of the frame 15, both ends of the frame 15 are joined with the same mold material as the frame 15 and arranged so as to form a ridge, and the lower frame 15a and one of the divided lower plate members 26a are joined. . Next, the sleeve 28 is attached to the through hole 27 of the lower plate 26a.
The cushioning material 29 on the contact part with the sleeve 28.
Place the pipe 11 wrapped around. Therefore, the other divided upper plate 26b is attached and fixed to the plate 26a at the same time.
It is also fixed to the upper frame 15b. Next, attach the elastic support mechanism for the pipe, and attach the auxiliary piping and auxiliary equipment.

It should be noted that placing the pipe 11 on the plate body 26 or the curing plate 31 during assembly is very effective for supporting the pipe 11 horizontally and for positioning the pipes 11 relative to each other. The piping in the piping unit 30 thus assembled is subjected to a pressure resistance and airtight test in a factory to confirm that there is no leakage at the joint. If necessary, painting work and heat insulation work will also be carried out in the factory,
30 is completed.

Further, when the rigidity of the piping unit 30 is insufficient only by connecting the plate body 26 and the frame 15 and inserting the pipe 11 into the sleeve 28 of the through hole 27 of the plate body 26, at a position that complements the rigidity, A curing plate made of wood, etc. formed by simplifying the plate 26.
31 may be provided as shown in phantom in FIG. At this time, the curing plate 31 is divided similarly to the plate body 26 so as to hold the pipe 11, but the curing plate 31 is generally formed of wood or the like,
It will be removed after it is installed in the building.

When the above-mentioned pipe support mechanism is not installed in the piping unit 30 because it is not necessary for the design, the piping 11 is the piping unit.
It loosens in the longitudinal direction within 30 and causes inconvenience during transportation and installation. In such a case, as shown in FIG. 6, a temporary fixing metal fitting 32 is attached to the curing plate 31, and the pipe 11 is temporarily fixed. This temporary fixing metal fitting 32 is also removed after being attached to the building.

By combining the pipe 11 and the frame 15 in this way, a pipe unit 30 having excellent strength and rigidity is completed, and most of the piping work itself is completed in the factory. Piping work for a building is carried out by transporting it from a factory to a construction site, installing it on a building frame 40, and joining it at a joint 33 between frames of a piping unit 30 and a joint 34 between pipes. Furthermore, by connecting the piping of the piping unit 30 to the piping of other parts of the building, or by directly connecting the piping unit 30 to the equipment such as the unit bath, air conditioner, and fire hydrant housing, the piping work for the building can be performed. Sometimes I do it. Figure 7 shows the piping unit 30
Is attached to the floor 25 of the building, one piping unit 30 vertically penetrates three floors of the building and includes not only the piping 11 but also auxiliary piping and auxiliary equipment.

When this piping unit 30 is attached to the building frame 40 of the building, as shown in FIG. 8, the mounting bracket 35 is attached to the frame 15, and the mounting bracket 35 is first attached as shown in (a). Temporarily fix it so that it is parallel to the frame 15. Then, after being suspended in the body 40 of the building, it is fastened by bolts and nuts 36 as shown in (b) and fixed so as to be placed on the floor of the building. Further, as shown in FIG. 9, it may be fixed by two mounting brackets 37 and bolts and nuts 38. Brackets 35, 37 here to the building frame 4
To fix it to 0, use the jack bolt 4 as shown in Fig. 10.
1 is attached, the height of the skeleton 40 and the construction error between the piping unit 30 are adjusted by the jack bolts 41, and the clamp bolts 42 are used to fix the clamp fittings 43.

In this way, the piping unit 30 pre-fabricated in the factory is carried into the building, installed, and connected to the piping between the piping units and the piping of other parts in the building, and the piping construction is completed and immediately usable. It will be in a state.
