  Hereinafter, the present invention will be described in more detail with reference to the examples of the drawings. A1, A2, and A3 are support brackets for supporting the lateral branch pipes, and these support brackets A1, A2, and A3 are the base plate 1 and the support plate, respectively. A pair of upright bolts 2 erected at both longitudinal ends of the base plate 1, a support plate 3 installed between the pair of upright bolts 2 by nuts 31 screwed on the upright bolts 2, and arranged on the support plate 3. A support band 4 is provided which has a pair of upper and lower parts and a lower band piece 41 which is connected in parallel to the drainage header 6 and is fitted with the side branch pipe 7 by an upper and lower band piece 42 which can be opened and closed. By setting the number of the bands 4 to three, two, and single, the number of the support bands 4 is changed to three types. At this time, the three types of support brackets A1, A2, and A are used. The support bands 4 on the support plate 3 are arranged in such a manner that the center support band 4 of the support metal fitting A1 in which the three support bands 4 are arranged can be freely angled in the horizontal direction, and the pair of support bands 4 on both sides can be horizontally angled.

The support bands 4 are formed so as to be freely angleable in the horizontal direction. The three types of support brackets A1, A2, and A3 for supporting the side branch pipes are used for the side branch pipes 7 as described later. The horizontal branch pipe support structure for supporting

  The base plate 1 is made of a plate made of thick steel plate having a length of about 50 cm for the support fitting A1, about 35 cm for the support fitting A2, about 23 cm for the support fitting A3, and a width of about several centimeters. An anchor through-hole 11 is provided at both ends in the longitudinal direction and further at an intermediate position as required, and nuts 12 for mounting upright bolts 2 are welded and fixed to the inner surfaces of the through-holes 11 at both ends.

  The pair of upright bolts 2 are erected upward on the surface of the base plate 1 by screwing the lower ends thereof to the nuts 12 of the base plate 1. Is about 12 to 13 cm.

  The support plate 3 has a length of about 40 cm at the support bracket A1, about 30 cm at the support bracket A2, and about 18 cm at the support bracket A3. The standing bolt 2 is inserted into the bolt through hole provided, and the edge of the bolt through hole is sandwiched between a pair of nuts 31 above and below screwed to the standing bolt 2, so that the 12 It is assumed that the pair of upright bolts 2 is installed and arranged at an arbitrary height of about ˜13 cm.

  The support band 4 installed on the support plate 3 has a pair of upper and lower parts, and semi-circular band pieces 41 and 42 are connected to a hinge 43 on a side surface on one end side thereof to connect the upper band piece 42 to the lower band piece 41. The support band A1, A2 and A3, which has an arcuate shape by closing the upper band piece 42 and making the inner diameter of the arc the same as the outer diameter of the lateral branch pipe 7, are openable and closable. By placing the horizontal branch pipe 7 on the piece 41 and closing the upper band piece 42, the horizontal branch pipe 7 is fitted and supported in a sandwiched manner. At this time, a lower fastening piece 44 is horizontally provided at the free end of the lower band piece 41 and a bolt through hole is provided in the surface thereof. For example, a nut 45 is welded to the lower surface of the lower fastening piece 41. While forming a female screw on the lower surface of the bolt through-hole, an upper fastening piece 46 is projected horizontally at the free end of the upper band piece 42, and the upper and lower fastening pieces 44, 46 are overlapped. The fastening pieces 44 and 46 can be fastened and fixed by screwing a hexagon bolt 48 to the female screw from the upper fastening piece 46 side. At this time, in this example, the upper fastening piece 46 The protrusion length is made shorter than the lower fastening piece 44, and a tip recess 47 such as a semicircle or a U shape with the tip opened is formed at the tip of the upper fastening piece 44. Make the opening width wider than the side dimension of the head of the hexagon bolt 48 Thus, the tip concave portion 47 can pass through the head of the hexagon bolt 48, whereby the hexagon bolt 48 is screwed to the nut 45 in advance and the hexagon bolt 48 is raised on the lower fastening piece 44. Then, after the horizontal branch pipe 7 is placed on the lower band piece 41, the upper band piece 42 is closed so that the head of the hexagon bolt 48 is received in the tip recess 47, and the hexagon bolt 48 is fastened. The band 4 can be fitted and supported by the side branch pipe 7 as easily as possible.

  In this example, the support band 4 is arranged on the support plate 3 so as to be freely angled in the horizontal direction, and the support band 4 is arranged on the support plate 3 so as to be slidable in the longitudinal direction. Thus, both the horizontal angle and the longitudinal slide can be made freely, and the support band 4 can be arranged in the horizontal angle direction in the lower band piece 41 of the support band 4. The downward bolt 5 is arranged on the support plate 3, the downward bolt 5 is inserted into the support plate 3, and the support band 4 is fixed to the support plate 3 by fastening the nut 52 from the lower surface side of the support plate 3. The support band 4 is assumed to have been allowed to rotate in the horizontal direction. The downward bolt 5 is inserted into the support plate 3 through a long hole 33 formed in the support plate 3. That is, the downward bolt 5 is similarly inserted into the lower band piece 41 of the support band 4. Is inserted into a long hole 33 oriented in the longitudinal direction of the support plate 3 which is formed through the support plate 3 in series or intermittently, and is supported by fastening the nut 52 from the lower surface side of the support plate 3. This is done by fixing the band 4 to the support plate 3 and allowing the support band 4 to rotate in the horizontal direction by relaxing the nut 52.

  As described above, the support band 4 of this example is in the support bracket A1 provided with the three support bands 4, the center thereof can be freely angled in the horizontal direction, and both the pair of both sides can freely be both horizontal angle and longitudinal slide. In the support bracket A2 having two support bands 4, both of which can freely slide in the horizontal angle and the longitudinal direction, and in the support bracket A3 having a single support band 4, It is assumed that the support band can be freely angled in the horizontal direction. At this time, the support plate 3 on which the support band 4 of this example is installed has the number of the support bands 4 on the horizontal plane of the steel plate having an L-shaped cross section. In the example, depending on the number of three, two and a single support band 4, for example, a through hole 32 for inserting a downward bolt 5 having a diameter of 9 mm and / or three long holes 33 for intermittent connection are provided. The through hole 32 or the long hole 3 It is to perform the fastening by the nut 52 of the support band 4 by inserting a downward bolt 5 of the support band 4. In this example, the long holes 33 have a pitch of 12 cm and a length of 4 cm so that the downward bolt 5, that is, the support bolt 4 can slide 3 cm in the longitudinal direction of the support plate 3. Therefore, the support band 4 slidable by providing the long hole 33 enables the horizontal branch pipe 7 to be supported according to the standard parallel pitch 12 cm connected to the drain header 6, while being L-shaped. For example, when the horizontal branch pipe 7 is bent through the elbow 71, the pitch of 12 cm is used, and, for example, the contact with a floor support leg (not shown) used for floor formation by using the parallel pitch of 12 cm is avoided. In order to improve workability by expanding the parallel pitch, for example, the case where the parallel pitch after bending is set to a maximum of 15 cm, the parallel in the field The pitch are so as to allow the support of the lateral branch pipe 7 corresponding.

  On the other hand, the downward bolt 5 inserted through the through hole 32 and / or the long hole 33 is formed by welding a nut 51 to the lower end of the lower band piece 41 of the support band 4 in the longitudinal direction and screwing the nut 51 to the lower band piece 41. Installation of the support band 4 having the downward bolt 5 on the support plate 3 integrally with the band piece 41 is performed by a washer between the nut 51 and the support plate 3 on which the downward bolt 5 is screwed. The downward bolt 5 is inserted into the through hole 32 and / or the elongated hole 33, and the nut 52 is fastened to the downward bolt 5 from the lower surface side of the support plate 3 through a washer. 3, the support band 4 is placed and fixed.

  As described above, the horizontal branch pipe support structure using the three types of support pipes A1, A2, and A3 for supporting the horizontal branch pipe has the above three support bands 4 and / or two and a single support band 4. By using A1, A2 and A3 together, the side branch pipe connected in parallel to the drain header 6 is supported by the side branch pipe in the vicinity of the drain header 6 and the elbow 71 at the corner connected by the elbow 71. Support bracket inclined intersection arrangement corresponding to expansion of parallel pitch in the side branch pipe 7 which is stable through the elbow 71 and the horizontal branch pipe support which is stable through the elbow 71 is supported. The horizontal branch pipe support with reduced protrusion width at the end of the support bracket is made free.

  In FIG. 10, the protrusion width from the side branch pipe 7 at the end of the support metal A1 is reduced by arranging the support metal A1 to be inclined and intersecting with the three side branch pipes 7 connected in parallel to the drain header 6. It is a top view which shows the use condition of support metal fitting A1, and this support metal fitting A1 supports this side branch pipe 7 by arranging this perpendicularly to this side branch pipe 7 in the straight part by the side of drainage header 6 at this time. On the other hand, the horizontal direction angle is inclined by the support band 4 by tilting the horizontal direction with respect to the support plate 3 so that the support metal fitting A1 is inclined and arranged in the side branch pipe 7 at the corner portion. In the straight part after supporting the branch pipe 7 and bending, the support metal A1 is also rotated and inclined so that the horizontal angle is inclined so as to be inclined and arranged on the horizontal branch pipe 7 as in the corner part. Support band There as supporting the transverse branch pipe 7 by. Accordingly, the protrusion width of the end portion of the support bracket A1 from the horizontal branch pipe 7 is reduced, and the danger caused by the operator's craving due to the protrusion of the end portion, or the operator hooks the skirt of the pants on the standing bolt 2. The risk of falling can be eliminated as much as possible.

  Further, when the above-mentioned support metal fitting B is supported at the corner portion so as to be orthogonal to the horizontal branch pipe 7, as shown in FIG. As a result, the lateral branch pipe 7 is supported at a position spaced apart from the corner portion. As a result, the inner and outer middle to outer sides of the outer branch pipe 7 are supported in order to support the load of the corner portion of the lateral branch pipe 7 including the elbow 71 and provide stable and reliable support. When it is necessary to additionally install another support bracket B at the corner portion of the side branch pipe 7, the support bracket A1 in this example supports the corner portion by three side branch pipes by the support bracket A1. 7 can be made directly and simultaneously in the vicinity of each elbow 71 of the corner portion, so that it is not necessary to install, for example, four support brackets B in FIG. As that number It can be reduced.

  In FIG. 12, for example, a total of five horizontal branch pipes 7 are connected in parallel to two drainage headers 6, one horizontal branch pipe 7 is bent near the drainage header 6, and two are bent at the tip. The horizontal branch pipe support structure in the case where two more pipes are extended in parallel from the drainage header 6 is shown. The five horizontal branch pipes 7 are divided into three and two. A support fitting A1 having three support bands 4 is arranged orthogonally to the horizontal branch pipe 7 in the vicinity of the drainage header 6, and a support fitting A2 having two support bands 4 is similarly connected to the horizontal branch pipe 7 in the vicinity of the drainage header 6. Each of the three lateral branch pipes 7 bent in the vicinity of the drainage header 6 is orthogonally arranged to support the three and two lateral branch pipes 7. A support bracket A3 provided with one is arranged so as to be inclined and rotated to the side branch pipe 7 to support the side branch pipe 7. The horizontal branch pipe 7 bent at the tip of the support pipe A2 is arranged at the corner to support the vicinity of the elbow 71 in the same manner as in the above example, and the support metal fitting A2 is also arranged at the intersection at the bent straight section. The horizontal branch pipe 7 supporting the horizontal branch pipe 7 and extending from the drainage header 6 in a parallel state is provided with a support bracket A2 having two support bands 4 at an inclined crossing at the straight portion. The branch pipe 7 is supported. As a result, even with the horizontal branch pipe support structure of this example, the need for additional support of the corner portion can be eliminated in the same manner as described above, and the risk of operator whispering can be prevented as much as possible by reducing the protruding width. I can do it.

  These support brackets A1, A2 and A3 are, for example, the base plate 1, the standing bolt 2, the support plate 3 and the support band 4 set in advance as support brackets at the site, and the base plate 1 is arranged orthogonally to the lateral branch pipe 7, respectively. After anchoring to the concrete slab so as to be inclined and arranged, or after fixing the base plate 1 to the base plate 1, the upright bolt 2, the support plate 3 and the support band 4 are set, and then a pair of uprights standing on the base plate 1. Adjusting the height of the support plate 3 by vertically adjusting the position of the nut 31 of the bolt 2, opening the upper band piece 42, opening the upper band piece 42, and connecting the drainage header 6 in parallel to the lower band piece 41 of the support band 4. 7 is placed, the upper band piece 42 is pivotally closed, and the upper fastening piece 46 and the lower fastening piece 44 are So as to fix the fastening by corner bolts 48 may be supporting the transverse branch pipe 7.
