In this case, since the fixing is not performed, the drain header is connected to the drain pipe, other drain headers, and the drain collecting pipe while the drain header floats from the floor due to the uneven surface of the concrete slab. It cannot be denied that there is a possibility that connection points may be loosened due to vibrations of the building or water leakage due to the vibrations of the building. On the other hand, it is assumed that an existing piping band, for example, a level band is used to fix the floor to the floor surface. In general, the level band is provided with a pair of bolts standing upright on the band board, and the relatively wide upper and lower band members are attached to the bolts. After the height is adjusted, the fastening pieces at both ends where the bolts are inserted are tightened by the upper and lower nuts of the bolts, and the pipe is fixed at a single point in the longitudinal direction. It is necessary to cut the width of the band member because the dimension between the horizontal branch pipes to be fixed with the band is narrow and the band member does not enter. Since the drain header is usually located close to the wall, for example, about 15 to 20 cm because it is installed near the wall, it is difficult to operate the spanner used to tighten the upper and lower nuts.

There are three places that hang down from the tube body 21 and protrude.
[0013]
In this example, the band substrate 2 is formed by applying a predetermined process to a flat steel plate having a relatively large area of about 15 × 20 cm with a thickness of about 2 mm, for example. In order to be able to selectively use the anchor 8 with an anchor bolt and a concrete nail, a plurality of large diameters for the anchor bolt, particularly two small diameters for the concrete nail, are provided at appropriate positions in the plane of the band board 2.

The amount of protrusion changes at each position of the bolt 9 by abutting and contacting, and when there is an inclination or unevenness in the concrete slab 40, this is absorbed, and the band board 2 is horizontally supported to fix the drain header 20. It can be made in the horizontal state of the band substrate 2. In the figure, reference numeral 11 denotes a locking nut which is used as needed for locking the bolt 9 in this embodiment.
[0015]
In this embodiment, a pair of the circular bands 12 is fixed to the band substrate 2 directly or indirectly through a receiving member at a contact point with the band substrate 2 at the lower end of the circumference. The fixing to the band board 21 in this embodiment is performed by welding the above-mentioned contacts directly to the upper surface of the band board 21 so that each circular band 12 stands upright, for example. With this arrangement, the pair of circular bands 12 can receive and support the tube body 21 with their openings directed in the same direction in the longitudinal direction of the tube body 21. In this case, the circular band 12 The width is made narrow, for example, about 1.5 cm, and the fixed interval is made, for example, about 12 cm. There as lifting acceptance supported in its longitudinal direction two positions according to the number.
[0016]
The circular band 12 is vertically divided into two parts, and one end of the divided end is connected to a hinge 16 so as to be freely openable and closable in the vertical direction. By projecting a pair of fastening projections 17 provided with a pair of fastening bands, the pair of fastening projections 17 can be fastened and fixed by downward bolts 19. The two divisions at 12 are performed such that the circles are approximately 1/2 circle at the horizontal position or the inclined position in the circumferential direction. If there is, it is provided with a vibration-proof rubber.
[0017]
That is, the circular band 12 according to the present embodiment is designed to fit the outer diameter of the tube main body 21. In addition to the outer diameter of the main body 21, for example, it is made of steel having an inner diameter of about 9 cm with respect to the outer diameter of the pipe main body 21 of about 8 cm. And a pair of upper and lower band members 13 and 14 which are substantially equally divided in the vertical direction by being divided into approximately 1/2 circles, and wound around one end of the divided end of each circular band 12. The upper band member 13 is vertically openable and closable with respect to the lower band member 14 by a hinge 16 constituted by a bearing arranged and a shaft inserted therein. Bend outward horizontally In this case, a pair of fastening projections 17 are arranged on the upper and lower sides of the lower band member 14 having a through hole in the plane. , A hexagonal nut is fixed to the lower surface of the lower fastening projection 17 in the superposed state, and a nut 18 is arranged on the lower fastening projection 17. Downward bolts 19 are screwed into the nuts 18 from the side of the fastening projections 17 through the through holes of the fastening projections 17, so that the pair of fastening projections 17 are fastened and fixed vertically. .
[0018]
The two divisions of the upper band member 13 and the lower band member 14 in the circular band 12 of the present example are set to the inclined positions. In this example, the joint 25 of the drain header 20 has fastening bolts 26 on both sides of the horizontal position. Therefore, when the drainage headers 20 are connected in a plural number in the longitudinal direction, the hinges 16 and the fastening projections 17 of the circular band 12, particularly the fastening projections 17 (or the nuts 18 and the like of the attachments) are provided. ) Is separated from the fastening bolts 26 to prevent the fastening bolts 26 from obstructing the receiving support of the drainage header 20 by the circular band 12, and when the drainage header 20 is used alone as described later. This is because the support band 1 can be commonly used for both connection and use in the longitudinal direction. It may be determined so as to form an angle of more than optimal 20 degrees, but in the present example is the same as an angle of about 30 to 35 degrees.
[0019]
To fix the floor surface of the drain header 20 using the support band 1, the band board 2 is leveled out by the height adjusting bolts 9, and the band board 2 is fixed to the concrete slab 40 by the fixing fittings 8 through the fitting holes 3. And the pipe body 21 of the drainage header 20 is received and supported by a plurality of open circular bands 12 at a plurality of positions sandwiching the horizontal branch pipe 22, the circular band 12 is closed, and the overlapped fastening projections 17 are formed. May be fastened and fixed with downward bolts 19. In the support band 1 of this embodiment, the horizontal branch pipe 22 is provided between the lower band members 14 of the pair of spaced circular bands 12 in which the upper band member 13 is opened. Is positioned so that the pipe body 21 of the drain header 20 is dropped onto the lower band members 14, and then each upper band member 13 is turned. The upper and lower band members 13 and 14 which are closed and fitted so as to cover the tube main body 21 may be fastened and fixed by the downward bolt 19 to the pair of fastening protrusions 17 of the upper and lower band members 13 and 14. By adjusting the positional relationship between the support band 1 for fixing the header 20 to the floor and the drainage pipe 30 and the like, the connection of the drainage header 20 to the drainage pipe 30 and the like is made after the floor is fixed. Can be.
[0020]
The support band 1 of the present embodiment can fix the drain header 20 to the floor surface and commonly use the drain header 20 regardless of the number of protrusions of the horizontal branch pipes 22 as long as the pitch of the horizontal branch pipes 22 is the same. Even in the case of connecting in a longitudinal direction so as to form a plurality of rows, there is no problem in receiving and supporting the pipe body 21 near the joint 25 by setting the two divisions of the circular band 12 to the inclined position.
[0021]
This will be explained with reference to the drawings. For example, in the case where the number of the horizontal branch pipes 22 is two, the horizontal branch pipe 22 located on the drain collecting pipe 30 side is connected to a pair of circular bands as shown in FIGS. The circular band 12 receives and supports the pipe body 21 between the two horizontal branch pipes 22 at the two places of the pipe main body 21 and the pipe main body 21 on the drainage collecting pipe 30 side so as to be sandwiched between the two. Similarly, the pipe main body 21 is received and supported at two places so as to sandwich the horizontal branch pipe 22 on the drain collecting pipe 30 side, or for example, as shown in FIGS. The pipe body 21 can be received and supported at two places between the adjacent lateral branch pipes 22 on both sides. Even in the case of more than three horizontal branch pipes 22, if the pipe main body 21 is similarly received and supported at two places so as to sandwich the horizontal branch pipe 22 between the arbitrary horizontal branch pipes 22 or the drain branch pipe 30 side. Good.
[0022]
For example, as shown in FIGS. 8 and 9, a drain header 20 having two horizontal branch pipes 22 and a drain header 20 having three horizontal branch pipes 22 are connected in a plurality, and in this example, two drain headers are connected. In the case of the connection shown in the figure, the pipe main body 21 located on the drainage collecting pipe 30 side in the drainage header 20 having the two horizontal branch pipes 22 on the left in the figure has three horizontal branch pipes 22 on the right in the figure. By being inserted into the joint 25 of the drainage header 20, it is located near the joint 25, but by dividing the circular band 12 into two inclined positions, the horizontal position of the pipe main body 21 in the circumferential direction on both sides in the circumferential direction is set. By receiving and supporting the pipe main body 21 while avoiding the tightening bolt 26, the pipe body 21 can be received and supported by the circular band 12 on the drain collecting pipe 30 side without any trouble.
[0023]
In the support band 1 of this embodiment, the pair of circular bands 12 allows the drainage header 20 to be received and supported at two longitudinal positions of the pipe main body 21 regardless of the number of the horizontal branch pipes 22 as long as the pitch is the same. To secure the floor surface in a stable manner, and to adjust the height of the band board 2 by the fixing bracket 8 and the leveling by the height adjusting bolts 9 in the downward direction without any lateral work. Opening and closing of the circular band 12, receiving and supporting the drainage header 20, and fastening with the downward bolt 19 of the circular band can also be performed downwardly on the support band 1 without lateral work. Therefore, even when the drain header 20 is located close to the wall, it can be easily and reliably fixed. By using the support band 1 exclusively for the drainage header 20, the width of the circular band 12 can be adjusted to the size of the pipe main body 21 excluding the horizontal branch pipe 22 of the drainage header 20, thereby facilitating on-site work. The drainage header 20 can be fixed to the floor stably over a long period of time. The structure of the support band 1 is simple, and a special tool is used for fixing the drainage header 20 to the concrete slab 40 and the floor of the drainage header 20 using the support band 1. Therefore, it is possible to achieve an operational effect such that the work such as a drill, a hammer, a spanner, a screwdriver and the like can be performed by a commonly used on-site tool without troublesome work, and the easiness of work can be ensured.
[0024]
Although the illustrated example is as described above, when the drainage header is used alone or when there is no obstacle due to the position of the fastening bolt of the above-described joint, the circular band is divided into two parts at a horizontal position in the circumferential direction of about 1 /. 2 holes, metal holes shall be for a single fixing metal, not for the above-mentioned plural metal fixings, and a number of height adjusting bolts shall be a minimum of three. It is also possible to use bolts with screw heads, etc. In implementing the present invention, a drainage header, a support band, a band board thereof, a height adjusting bolt, a circular band, a fastening protrusion, and a downward facing Various specific shapes, structures, materials, their relations, such as bolts and vibration damping materials used as necessary, additions thereto, and specific methods of fixing the floor surface, etc., may be various unless they violate the gist of the invention. Can be in the form .
