Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe supporting base which can be suitably used for installing a pipe on the roof of a building, newly installing the pipe, or temporarily removing the pipe for repairing waterproofing treatment. .

[0002]

2. Description of the Related Art A water supply tank and a water cooler for an air conditioner are installed on the roof of a building. A water pipe connected to the water absorption tank and the water cooler is made of concrete block or metal. Horizontally supported by a steel pipe support base (hereinafter simply referred to as a base)
It is common to arrange them at a certain height above the roof surface. As the frame, for example, as shown in FIGS. 4 (a) and 4 (b), a base formed by packing the lower end of a portal frame 12 with a mortar 13b in a round pipe 13a made of round vinyl chloride. 13 is widely spread, a pipe P around which the heat insulating material 10 is wound is applied to the upper surface of the horizontal portion 12a of the portal frame 12, and is fixed with the inverted U-shaped bracket 11 and the nut 15. . In addition, since waterproofing is indispensable on the roof of the building, the gantry is usually
The waterproof sheet 14 is laid or the like, and is installed after the waterproof processing is completed.

[0003]

Since the rooftop is stepped or inclined, the length of the base varies depending on the place where the roof is used, and the mortar is used to form the foundation. Due to the use, it is reasonable to construct at the site where the length of the leg is determined. However, for that purpose, specialized work such as metal working, mortar filling, pipe fixing, etc., is performed separately, so that it is complicated to set up the work. If the waterproofing process is incomplete, rainwater will infiltrate from there, and it will often run down the waterproof layer and leak from a location away from the intrusion, so it is difficult to identify the leak location, and even in one place The waterproofing process must not be defective. At the time of the new installation, since the piping work is performed after the completion of the waterproofing process as described above, the waterproofing process does not become incomplete. However, in the renovation work, if waterproofing is performed without removing the frame, cover the entire surface with a sheet or repair the seam with a sealing material so that it does not run around the boundary and the back surface along the surface of the foundation as well as the boundary. Since it is indispensable, workability is extremely poor, and there is a high possibility that the waterproof treatment is incomplete, and there is also a problem in durability. On the other hand, if the gantry is removed and renovated, perfect waterproofing comparable to that at the time of new construction can be expected, but since the conventional gantry is integrated with the foundation and the portal frame,
To remove from the pipe, the frame must be cut and separated from the base, so that it is impossible to reuse the gantry once removed.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A gantry according to the present invention will be described with reference to the drawings, taking an example in which two pipes are supported. In FIG. 1, reference numerals 1 and 1 denote bases made of a metal plate, rubber plates 2 and 2 are adhered to the bottom surface, and columns 3 and 3 having a U-shaped cross section are fixed upright at the center of the surface. The bases 1 and 1 are connected to each other by a thin plate 4 made of metal and having a spring property. A plurality of slits 3 as a plurality of locking holes are formed along the column 1 on the U-shaped back surface of the columns 3 and 3.
are formed at equal intervals.

Reference numeral 5 denotes a horizontally long pipe fixing bar having an inverted L-shaped cross section. A horizontal portion of the pipe fixing bar 5, except for a part of both ends, is used to insert a long and thin bolt along the longitudinal direction. A slit 5a is formed. 6 is the column 1,1
Locking pieces 6a, 6a are cut and raised at both end faces of the beam 6, and bolt insertion holes for mounting the receiving table 7 are provided at two places on the horizontal upper surface. Elongated holes 6b, 6b are provided.

The receiving base 7 is formed by fixing a receiving plate 7b to the upper end of a bolt portion 7a.
By forming the receiving plate 7b with the V-shaped bent plate body, the receiving surface is formed in a V-shape so that the vertical plate portion of the pipe fixing bar 5 can be easily introduced into the center. The receiving stand 7 is provided with a pair of fastening nuts 8 and 9 corresponding to the bolt portions 7a.

[0008] The mounting of the pedestal composed of these members is carried out by first inserting one fastening nut 8 into the bolt portion 7 a of the receiving stand 7 and then inserting the bolt portion 7 a into the bolt insertion length of the beam 6. The cradle 7 is attached to the beam 6 by inserting the other fastening nut 9 into the bolt portion 7a penetrating downward through the hole 6b from above.
Next, the upper ends of the columns 3, 3 are widened to the right and left by using the bending of the plate 4, and the beam 6 to which the pedestal 7 is attached is introduced between the columns 1, 1, so that the beam is close to a desired height. By inserting the tip of the locking piece 6a into the slit 3a and locking it,
The beam 6 is erected between the columns 3 and 3. In addition, the cradle 7
Can be attached after the beam 6 is erected between the columns 3 and 3.

In order to fix the pipe, the pedestal having been assembled is placed in an installation place, and is temporarily supported, for example, by receiving the pipe fixing bar 5 on the receiving plate 7b of the pedestal 7, and temporarily held. Heat insulation material 1
Put the pipes P, P covered with 0, and check whether the pipe P is supported at an appropriate height. If it is determined that the height of the pipe P is inappropriate, the height of the beam 6 is corrected by changing the slit 3a to be locked by the locking piece 6a, or the tightening nuts 8, 9 are turned to receive the pipe P. This is dealt with by adjusting the height of the table 7. Finally, inverted U-shaped bracket 11
And a nut, a pipe P covered with a heat insulating material 10,
P is fixed to the pipe fixing bar 5.

As described above, the beam 6 can be attached to the columns 3 and 3 by one-touch operation, and the height of the beam 6 is determined by the slits 3a and 3 to which the locking pieces 6a are inserted.
can be freely changed by selecting a .. The delicate height of the cradle 7 can be adjusted by turning the fastening nuts 8 and 9. Further, since the rubber plate 2 is adhered to the back surface of the base 1, there is no danger of damaging the waterproof sheet even if it is installed on the waterproof sheet, and the receiving base 7 has a V-shaped receiving surface. As a result, the vertical plate portion of the pipe fixing bar 5 can be reliably introduced into the center of the receiving surface. And since it can be easily disassembled by taking the reverse procedure to the above assembling, it can be dealt with whenever removal is necessary, such as replacement work of the waterproof sheet, etc.In that case, it will not be cut off, so all members are Reusable. Needless to say, the procedure of assembling and disassembling is appropriately changed according to the working conditions and the judgment of the operator.

Next, an example will be described in which an existing gantry is replaced with a gantry of the present invention when a waterproof sheet is replaced at a site where a gantry of a conventional model is used. For this purpose, the gantry of the present invention is first installed as a temporary gantry B at a position away from the existing gantry A and under the pipe P (a in FIG. 3), and the existing gantry A is removed. To remove the existing gantry A, the portal frame 12 is cut and the horizontal portion 12a is attached to the leg 1
2b, the horizontal portion 12a is kept fixed to the pipe, and the leg portion 12b is removed together with the foundation 13 (FIG. 3).
B). Then, the old waterproof sheet 14 'laid on the surface where the existing stand was installed is peeled off, and a new waterproof sheet 14 is laid (c in FIG. 3). Since the waterproofing of the re-sealed portion becomes perfect by replacement with the new waterproof sheet 14, the gantry of the present invention is installed as a new gantry C in that portion. In this case, the horizontal part 12a of the portal pipe 12 in the existing gantry A to which the pipe P is fixed is used as a pipe fixing bar, and the horizontal part 12a used as the pipe fixing bar is held by a receiving table. , Remove the temporary base B that is no longer needed (FIG. 3e),
The repair work is completed by replacing the temporary base B with a new waterproof sheet 14 after the removal. At this time, if a part of the leg or both ends of the horizontal part is in the way, the part that is in the way can be cut as shown. The part that has been restored is covered with a new waterproof sheet 14, and the new stand C
Is installed on the upper surface of the waterproof sheet 14 after the replacement, so that no sealing process is required between the waterproof sheet and the base.

As described above, in the gantry of the present invention, the existing gantry is replaced with the gantry of the present invention by utilizing the opportunity to repair the waterproof layer, and at this time, the gantry of the present invention is used as a temporary gantry. You can also. In addition, even when replacing the gantry, the temporary gantry is installed after replacing the waterproof sheet,
