Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a riser unit reinforcing device for a structure for constructing a riser, which is a vertical pipe installed in a piping space in a structure such as a building or an apartment complex.

[Background technology]

When installing vertical piping into the piping space of a building, it is necessary to connect each type of piping, such as hot water supply and drainage, to the piping on the lower floor, and to connect the outlet piping and metering meter to each room. Installation, leveling, and connection of these piping and meters must be carried out in a narrow piping space within the structure.
Assembling is done while adjusting the dimensions based on the current layout, which is a complicated and time-consuming process.

On the other hand, by manufacturing units in advance that connect the vertical pipes on each floor parallel to each other and connecting these units to the units on the lower floors, there is no need to adjust the levels of each pipe on site. become. However, in order to use this unit piping, each piping must be thick enough to withstand the load during assembly and transportation without deforming. For this reason, in housing complexes and the like that use thin pipes, it is necessary to connect and reinforce the thin pipes with each other using a high-strength frame to reinforce the pipes, which results in heavy weight and increased costs.

In consideration of the above-mentioned facts, the present invention aims to provide a riser unit reinforcing device for a structure in which thin piping is manufactured in advance as a riser unit and the riser unit can be easily installed in the piping space of the structure.

[Summary and operation of the invention]

The present invention includes a reinforcing table on which a piping support frame forming a part of a riser unit is placed, and a temporary fixing means provided on the reinforcing table for temporarily fixing the piping support frame to the reinforcing table. It is characterized by

In this way, when using the present invention, when attaching a plurality of relatively thin riser pipes to the support frame, the support frame is temporarily fixed on the reinforcing table, so the support frame does not have sufficient strength. It is also possible to support the load applied to the piping during assembly. In addition, even if the riser piping is attached to the support frame at the factory and then brought to the work site, the load applied during transportation will be reliably supported by the reinforcing table, so the support frame and riser piping will be placed at a high There is no deformation even if it is not strong.

If pressure contact means for holding the support frame between the support frame and the bracket erected from the reinforcing stand is used as the temporary fixing means, the riser unit can be easily released from the hold at the construction site. After this is released, lifting the riser unit is easy if the load of the riser unit is supported by the stopper attached to the reinforcing stand.

After the riser unit is lifted, it is carried into the piping space within the structure, and generally during construction of the structure, the riser piping is inserted into the piping space from the top of the structure.

For this reason, the riser unit is lifted by a crane or the like via a support frame, but the support frame only needs to have enough strength to withstand the load during assembly, and the load applied during transportation. Since it is not necessary to withstand a load, the support frame can be constructed from a relatively small diameter angle member or the like.

[Embodiments of the invention]

1 and 2 show a riser unit 10 to which the present invention is applied, assembled in a factory or the like. This riser unit 10 is in a state in which various pipes 14 are attached to a support frame 12, and the support frame 12 is temporarily fixed to a reinforcing stand 16.

The reinforcing stand 16 has a high-strength structure in which two parallel H-shaped ropes are connected to each other by an angle member 16A to form a frame shape. (The reinforcing table 16 is shown in phantom lines in FIG. 2).

The support frame 12 is constructed by combining angle members with each other, and has a pair of parallel long sides 12A and short sides 12B, and both longitudinal ends of these are welded to each other to form a frame shape and reinforced. It is mounted on stand 16. A plurality of mutually parallel connecting sides 12C span the longitudinally intermediate portion of the long side 12A. Moreover, a rope rod 20 which is inclined with respect to the longitudinal direction is stretched between the long sides 12A at an appropriate position.
A turnbuckle 2 is installed in the middle of these rope rods 20.
2 are provided to modify the effective length of the rope rods 20 and to reinforce the support frame 12.

The plurality of pipes 14 have a short side 1 parallel to the long side 12A.
2C, and is fixed to the short side 12C with a U bolt 24 and a nut (not shown). In this embodiment, there are six pipes 14A to 14A as shown in FIG.
14F is used, and these are for drainage, water supply, gray water supply, hot water supply, heating hot water supply, and heating hot water return.

As shown in FIG. 2, these pipes 14A to 14F have one end connected to one support frame short side 12B.
The other end protrudes from the other support frame short side 12.
It is located inside B. Also, piping 14D
Flanges are fixed to the ends of these pipes, except for the pipes, for connection with flanges on the corresponding lower or upper floors, and the end faces of these flanges are located at approximately the same position in the longitudinal direction of the pipes. There is.

However, the end positions and shapes of these pipes are not limited to the above structure, and may be arranged so that the support frame 12 does not interfere with the connection when connected to the pipes on the upper or lower floors. The structure is not limited to flange connection, and various types of tube shaft structures can be applied.

In Figures 3 and 4, the support frame 12 is
A configuration for temporary fixing is shown. A bracket 28 is erected from a part of the reinforcing table 16, and a press block 30 is closely attached to the bracket 28 to constitute a temporary fixing means. The pressure contact block 30 is fixed to the mounting bolt 32 by screwing the nut 34 onto the mounting bolt 32 passing through the bracket 28 and the pressure contact block 30.

The pressure welding block 30 has a thin wall portion 30A at the end facing the reinforcing table 16, and a part of the long side 12A is accommodated between it and the bracket 28, thereby attaching the support frame 12 to the reinforcing table 16. It is supposed to be temporarily fixed. The long side 12A may be sandwiched between the thin wall portion 30A and the bracket 28.

As shown in FIG. 5, one of the pair of short sides 12B comes into contact with a stopper 36 fixed to the reinforcing base 16. This stopper 36
constitutes a part of the temporary fixing means, so that the riser unit 10 will not be displaced from the reinforcing stand 16 even when the reinforcing stand 16 is placed against the outside of the structure 40 at the construction site as shown in FIG. ing.

A meter box frame 42 is erected from the support frame 12. In this meter box frame 42, a pair of mounting frames 44 formed of angle members in a U-shape are fixed parallel to each other on the long side 12A, and these mounting frames 44 are connected to each other by a connecting angle 46. As shown in FIGS. 6 and 7, the outlet pipe 48 (48B to 48F), which has a meter 50, a valve 52, etc. in the middle part, is connected to the branch pipe 14.
8 (148B to 148F) to each pipe 14
(14B to 14F) at right angles.

The extraction pipes 48 (48B to 48F) are parallel to each other and are arranged horizontally when attached to the structure. In addition, these tips connect to the piping in each level of the structure 248 (248B to 2).
48F).

Among these, the outlet pipe 48F is the branch pipe 148F.
Although the extraction pipes 48B to 48E are directly connected to
The outlet pipes 348 (348B to 348E) are connected at right angles to the opposite side of the connecting portion 248 (248B to 248E), and the tips of these outlet pipes 348 are connected to the piping 4.

48B to 448E), and the tips of these extraction pipes 448 are connected to the branch pipes 148 (148B to 448E).
148E) at right angles to each other. Therefore, the pipe 48 and the outlet pipes 348, 448 are the pipe 14.
The outlet pipes 348 (348B to 348E) are U-shaped when viewed from the axial direction of the pipe 14 as shown in FIG.
It is located at the same location as the 8th floor.

Therefore, the linear length L of the take-out pipe 48 (48B to 48F) necessary for attaching the meter 50 and the valve 52 can be accommodated within the meter box frame 42 as shown in FIG.

If the branch pipe 148 is directly connected to the piping 48 without using these outlet pipes 348, 448, the length L of the linear section necessary for installing meters will protrude from the meter box frame 42 as shown in FIG. The width dimension of the frame 42 must be S ₁ , and as in this embodiment, the width dimension must be S ₀
Therefore, it is not possible to reduce the piping space within the building.

Note that each pipe 48 (48B to 48F) is fixed to the connecting angle 46 with a U bolt 53 (FIG. 6) or the like. Moreover, the drainage pipe 14A is connected to the pipes of each floor via a branch pipe 148B (FIG. 7).

As shown in FIG. 1, the support frame 12 has a pair of hooks 54 attached to the end of the long side 12A and a pair of hooks 56 attached to the end of the meter box frame 42 for hanging.

Furthermore, the riser unit 10 shown in FIGS. 1 and 2 is shown in a state in which riser units of multiple levels (three levels in this example) are configured together, and riser piping for three levels of the structure is handled at once. Construction is now possible. Therefore, three sets of meter box frames 42 are used for three layers.

When manufacturing such a riser unit 10, the long side 12A is placed on the reinforcing table 16 by the bracket 2.
8. Fix with the press block 30, and connect the support frame short side 12B and connecting side 12 to these long sides 12A.
C, fix the rope 20 and connect each pipe 14 with the U bolt 2
Fix it at 4. Furthermore, the riser unit 10 is completed by attaching the outlet pipes 48 to these pipes 14, fixing the meter box frame 42 to the support frame 12, and fixing the outlet pipes 48 to these meter box frames 42.

This manufacturing work can be done not at a construction site but at a place with sufficient space such as a factory, so the work is easy, and since the support frame 12 is made of a small diameter angle material, it is easy to handle.
However, since the reinforcing table 16 reliably supports the load of each pipe 14, the support frame 12 will not be deformed.

After fabrication, pressure water is supplied to each pipe 14 to perform a water pressure test to confirm the sealing performance of each connection.

The riser unit 10 configured in this way,
A plurality of reinforcing stands 16 can be transported to the site by a truck or the like in a stacked state via a cushioning material (not shown). The riser unit 10 and reinforcement stand 16 brought to the site are placed diagonally against the outer wall of the structure 40, as shown in FIG. Since the load that is applied during transportation is supported by the reinforcing table 16, the support frame 12
will not deform even if it is not high strength.

At this point, a lifting wire 60 from a crane (not shown) is hung on the hooks 54 and 56, and the press block 30 is removed from the bracket 28 to release the hold state of the riser unit 10 and allow the stopper 36 to support the load. Thereafter, as shown in FIG. 9, the lifting wire 60 is lifted to lift the riser unit 10. In this case, the lifting wire 60
An auxiliary wire 62 whose lower end is locked to the hook 54, and an auxiliary wire 6 whose lower end is locked to the hook 56.
By adjusting the length of the riser unit 4, the riser unit 10 can be accurately suspended vertically. A turnbuckle 65 is interposed in the middle of the reinforcing wire 64 to adjust its length.

For this reason, the riser unit 10 in the vertical state is connected to the slab 40 of the structure 40, as shown in FIG.
It can be accurately lowered into the narrow piping space 66 formed at A and 40B.

While the riser unit 10 is lowered and mounted on or close to the already installed lower riser unit 10A, the riser unit 10 is temporarily fixed to the leveling frame 68 installed on the slab 40B. In this horizontal frame 68, a horizontal pipe 68B is spanned over four vertical pipes 68A surrounding the riser unit 10, and the horizontal pipe 68B is formed in a planar cross-frame shape and arranged around the riser unit 10. It's becoming like that.

The intermediate portion of the support frame 12 is temporarily fixed to this horizontal pipe 68B using a wire or the like. The vertical pipes 68A connect to the slab 40 through each stand 70.
The stand 70 and the vertical pipe 68A are screwed together with a screw whose axis is vertical. Therefore, the heights of the four vertical pipes 68A can be adjusted separately by rotating one or more of the stands 70 at the lower ends of the four vertical pipes 68A, thereby making it possible to adjust the height of the four vertical pipes 68A separately. It can be accurately arranged vertically and can be accurately aligned and connected to the piping 14 of the lower riser unit 10A. These pipes 14 are connected using flanges formed at their ends. Thereafter, the leveling frame 68 is removed, and a portion of the riser unit 10 is fixedly supported on the slab 40A of the structure 40.

When all of the riser units 10 on multiple levels of the structure 40 are installed in this way, the pipes in each room and the pipes 14 are connected using the take-out pipes 48. Furthermore, an in-building partition is provided around the riser unit 10 before or after the riser unit 10 is installed.
The water pressure test including the outlet pipe 48 has already been completed, and since the outlet pipe 48 is connected to the piping 14, the outlet pipe 48 is connected to the piping 14 at the construction site.
There is no need to connect the pipe to the extraction pipe 48.
All you have to do is connect the pipes to each room's pipes, so it's not a difficult task even if you have a small space.

Further, the reinforcing table 16 from which the riser unit 10 has been removed can be used repeatedly several times.

Note that the means for temporarily fixing the riser unit to the reinforcing stand is not limited to the above structure, and various other means can be applied.

〔Effect of the invention〕

As explained above, according to the present invention, the riser unit can be transported with it temporarily fixed to the reinforcing stand, so there is no need to make the riser unit high-strength, and the riser unit can be moved by simply connecting the pipes. It has the excellent effect of making assembly possible.
