Description

  The present invention relates to a side branch pipe support fitting used to support a side branch pipe connected in parallel to a drainage header on a concrete slab and a side branch pipe support structure using the same.

  As this kind of horizontal branch pipe support fitting, the present applicant has installed a base plate, a pair of upright bolts erected at both ends in the longitudinal direction of the base plate, and a pair of upright bolts by nuts screwed to the upright bolts. A support plate, and a support band for placing the horizontal branch pipe on the lower band piece in the upper and lower pair disposed on the support plate and fitting the horizontal branch pipe with the upper and lower band piece that can be freely opened and closed. A lateral branch pipe support fitting that has been arranged perpendicular to the pipe to support the lateral branch pipe has been proposed. At this time, the lateral branch pipe support fitting has its support band supported on the support plate. It is supposed to be slidable in the longitudinal direction of the plate.

  In this case, by adjusting the height of the support plate with respect to the standing bolt, it is possible to cope with the inclination of the side branch pipe to provide a water gradient according to the distance of the side pipe connected in parallel to the drainage header, and to the drainage header. The pitch of the connected side branch pipes is generally a standard pitch of 12 cm. When bending by connecting with an elbow, the pitch of the side branch pipes is avoided from contact with the floor support legs used for floor formation. For the purpose of improving the workability of the branch pipe piping work, for example, it is often 15 cm. However, by sliding the support band on the support plate, the straight portion of the horizontal branch pipe and Support at the corner can be efficiently performed by a simple operation regardless of the height and pitch.

  However, in this case, the length of the support plate in the horizontal branch pipe support bracket is a length in which a margin width is arranged so that it does not abut against the standing bolt even if the support band is slid at both ends. The length of the horizontal branch pipe support fitting is determined by the length of the support plate or the length of the standing bolt that supports the support plate and the fixed width for fixing to the concrete slab with an anchor. Inevitably tends to be considerably longer than the parallel total width of the horizontal branch pipes. At this time, the horizontal branch pipe support fittings are arranged so as to be orthogonal to the horizontal branch pipes connected in parallel to the drainage header. Since the horizontal branch pipe is used to support the horizontal branch pipe, when supporting the horizontal branch pipe using the horizontal branch pipe support fitting, the longitudinal end of the horizontal branch pipe support fitting is provided at the widthwise end of the horizontal branch pipe. Club, especially base play It is unavoidable that the end of the support plate protrudes relatively large, and the projecting portion is present in a concrete slab in which a large number of pipes are arranged. There remains a problem that it is easy to incur the risk of falling by hooking the bottom of the pants on the standing bolt at the end of the plate.

  Further, in this case, since the horizontal branch pipe support fitting is arranged perpendicular to the horizontal branch pipe and supports the horizontal branch pipe, for example, as shown in FIG. When the corner portions of a plurality of side branch pipes connected in parallel are connected to each other, the side branch pipe support fitting is supported at the corner portion of the side branch pipe located inside the corner portion. The load including the elbow can be supported, but the support from the middle to the outside is a straight part away from the corner, so that it is further supported by the middle and outer side branch pipes other than the inside. It will be necessary to install side branch pipe support fittings. After all, in order to stably and reliably support the side branch pipes with the side branch pipe support fittings at the corners, the number of the side branch pipe support fittings increases.

It is possible to provide a side branch pipe support structure capable of reducing the number of side branch pipe support fittings for supporting inner and outer middle to outer side branch pipes as much as possible.

  Hereinafter, the present invention will be described in more detail with reference to the examples of the drawings. A1, A2 and A3 are three types of horizontal branch pipe support fittings in the present example. A2 and A3 are a base plate 1, a pair of upright bolts 2 erected at both longitudinal ends of the base plate 1, and a support plate installed between the pair of upright bolts 2 by nuts 31 screwed on the upright bolts 2. 3 and a lateral branch pipe in which the lateral branch pipe 7 is placed on the lower band piece 41 in a pair of upper and lower sides arranged on the support plate 3 and the lateral branch pipe 7 is fitted by an upper and lower band piece 42 that can be freely opened and closed. It is assumed that the support bracket A1 is provided with three, the side branch pipe support fixture A2 is provided with two, and the side branch pipe support fixture A3 is provided with a single support band 4. At this time, the side branch pipe support fixtures A1, A2 and A3 are provided. Is There as those freely supporting the transverse branch pipe 7 is inclined intersect the horizontal branch pipe 7 by placing horizontal angle freely the support band 4 on the support plate 3.

  The base plate 1 has a length of about 50 cm for the side branch pipe support fitting A1, about 35 cm for the side branch pipe support fitting A2, about 23 cm for the side branch pipe support fitting A3, and has a width of about several centimeters. An anchor through-hole 11 is provided at both ends in the longitudinal direction, if necessary, at an intermediate position, and nuts for screwing up standing bolts 2 on the inner surfaces of the through-holes 11 at both ends. 12 is welded and fixed.

  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 length of the support plate 3 is about 40 cm in the side branch pipe support fitting A1, about 30 cm in the side branch pipe support fitting A2, and about 18 cm in the side branch pipe support fitting A3, for example, a steel plate having an L-shaped cross section. The upright bolt 2 is inserted into bolt through holes provided at both ends of the horizontal plane, and the edges of the bolt through holes are sandwiched between a pair of nuts 31 that are screwed into the upright bolt 2. Thus, the standing bolt 2 is constructed so as to be erected with respect to the pair of standing bolts 2 at an arbitrary height of about 12 to 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, whereby the upper band piece 42 is connected to the lower band piece 41. The horizontal branch pipe support fittings A1, A2 and A3 have a common diameter that is openable and closable and forms a circular arc by closing the upper band piece 42 and the inner diameter of the circular arc matches the outer diameter of the horizontal branch pipe 7. The horizontal branch pipe 7 is placed on the lower band piece 41 and the upper band piece 42 is closed to support the horizontal branch pipe 7 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. In this state, a female screw is formed on the lower surface of the bolt through-hole, while an upper fastening piece 46 is horizontally projected at the free end of the upper band piece 42 and the upper and lower fastening pieces 44, 46 are superposed. The fastening pieces 44, 46 can be fastened and fixed by screwing the 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 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 recess 47 can pass through the head of the hexagon bolt 48, whereby the hexagon bolt 48 is screwed into the nut 45 in advance and the hexagon bolt 48 is raised on the lower fastening piece 44. Then, after placing the horizontal branch pipe 7 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 disposed on the support plate 3 so as to be freely angled in the horizontal direction, and the support band 4 is disposed on the support plate 3 so as to be slidable in the longitudinal direction thereof. Accordingly, the horizontal angle and the longitudinal slide can be freely adjusted, and the horizontal angle can be freely arranged by attaching a downward bolt 5 to the lower band piece 41 of the support band 4. Then, 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 allowed to be freely angled in the horizontal direction by allowing the direction to rotate, and both the angle in the horizontal direction and the slide in the longitudinal direction are both self-adjusted. In this case, 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 lower band piece 41 of the support band 4 is similarly used. A downward bolt 5 is arranged on the support plate 3, and the downward bolt 5 is inserted into a long hole 33 extending in the longitudinal direction of the support plate 3, which is inserted in series or intermittently in the support plate 3. The support band 4 is fixed to the support plate 3 by wearing, and the support band 4 is allowed to rotate in the horizontal direction by allowing the support band 4 to rotate in the horizontal direction due to the relaxation of the nut 52, thereby allowing the support band 4 to freely move and slide. It is as.

  The support band 4 of this example is in a horizontal branch pipe support bracket A1 having three support bands 4, the center of which is freely adjustable in the horizontal direction, and the pair of both sides is free of both horizontal angle and longitudinal sliding. The horizontal branch pipe support fitting A2 having two support bands, both of which can freely slide in the horizontal angle and the longitudinal direction, and the single support band 4 is provided in the horizontal branch pipe support fitting A3. In this case, 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 surface of the steel plate having an L-shaped cross section, three, two and a single in this example. Depending on the number of support bands 4, for example, a through-hole 32 through which a 9 mm-diameter downward bolt 5 is inserted and / or three elongated holes 33 that are intermittent are provided, and the support band 4 is inserted into the through-hole 32 or the long hole 33. A downward bolt 5 is inserted to fasten the support band 4 with the nut 52. In this example, the long holes 33 have a pitch of 12 cm and a length of 4 cm, and the 9 mm diameter 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 which is slidable by providing the elongated hole 33 enables support of the lateral branch pipe 7 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 above-mentioned 12 cm pitch is avoided. In order to improve workability by expanding the parallel pitch, for example, the parallel pitch in the field including the case where the parallel pitch after bending is set to 15 cm maximum 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 into the through hole 32 and / or the long hole 33 is welded to the lower end of the lower band piece 41 of the support band 4 with a nut 51 and screwed to the nut 51. The support band 4 having the downward bolt 5 is integrally installed on the band piece 41 and the support plate 3 is installed on the support plate 3 through a washer between the nut 51 on which the downward bolt 5 is screwed and the support plate 3. 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.

  The horizontal branch pipe support fittings A 1, A 2 and A 3 formed in this way are formed by inclining the horizontal branch pipe support fitting to the horizontal branch pipe 7 at the straight portion or corner portion of the horizontal branch pipe 7 connected to the drain header 6. Arranged and used to support the lateral branch pipe 7 by the lateral branch pipe support fittings A1, A2 or A3, either alone or using, for example, the lateral branch pipe support fittings A1 and / or A2 and A3 in combination It is as.

  That is, FIG. 10 shows an example in which the three side branch pipes 7 connected in parallel to the drainage header 6 are supported by the side branch pipe support fitting A1 having the above three support bands. The metal fitting A1 supports the horizontal branch pipe 7 by arranging it at a straight line portion on the drainage header 6 side and orthogonal to the horizontal branch pipe 7, while the horizontal branch pipe support metal fitting A1 is connected to the horizontal branch at the corner portion. After the tube 7 is inclined and intersected with the support plate 3, the horizontal branch tube 7 is supported by the support band 4 that is inclined in the horizontal direction with respect to the support plate 3, and is bent. The horizontal branch pipe support fitting A1 is arranged so as to be inclined and intersected with the horizontal branch pipe 7 in the same manner as in the corner portion, and the horizontal branch is supported by the support band 4 that is also rotated and inclined to incline its horizontal angle. Assume that tube 7 is supported This reduces the projecting width of the end of the side branch pipe support fitting A1 from the side branch pipe 7, and the danger caused by the operator's scooping due to the protrusion of the end, It is possible to eliminate as much as possible the danger of falling by hooking the hem.

  Further, for example, in the case where the preceding horizontal branch pipe support fitting B is arranged perpendicularly to the horizontal branch pipe 7 and supported at the corner portion, as shown in FIG. On the other hand, in order to support the load of the corner portion of the side branch pipe 7 including the elbow 71 to support it stably and surely as a result of the support of the inner and outer middle to outer side branch pipes 7 at a position separated from the corner portion. When it is necessary to additionally install another side branch pipe support fitting B at the corner portion of the inner and outer middle or outer side branch pipe 7, the corner part is supported by the side branch pipe support fitting A1 of the present example. The three side branch pipes 7 can be formed directly and simultaneously in the vicinity of the elbows 71 at the corner portions by the side branch pipe support fittings A1, thereby supporting the inner and outer middle to outer side branch pipes 7 at the corner portions. , For example, the four sides of FIG. As required the installation of tube support bracket B, it is possible to reduce the number.

  In FIG. 12, for example, a total of five side branch pipes 7 are connected in parallel to two drainage headers 6 and one side branch pipe 7 is bent in the vicinity of the drainage header 6 and two are bent at the tip. In addition, the configuration of supporting the lateral branch pipe 7 when two are further extended in parallel from the drainage header 6 is shown. The five lateral branch pipes 7 are divided into three and two. Separately, the side branch pipe support fitting A1 having the three support bands 4 is arranged orthogonally to the side branch pipe 7 in the vicinity of the drainage header 6, and the side branch pipe support fitting A2 having the two support bands 4 is similarly arranged as the drainage header. 6 is arranged orthogonally to the horizontal branch pipe 7 and supports three and two horizontal branch pipes 7 respectively, while one of the three horizontal branch pipes 7 bent near the drainage header 6 is bent. The horizontal branch pipe support fitting A3 provided with one support band 4 at the straight portion is arranged so as to be inclined and rotated to the horizontal branch pipe 7. The side branch pipe 7 that supports the side branch pipe 7 and is bent at the tip of the side branch pipe 7 supports the vicinity of the elbow 71 by tilting the side branch pipe support fitting A2 at the corner portion as in the above example. Similarly, the horizontal branch pipe support fitting A2 is inclined to support the horizontal branch pipe 7 at the straight portion, and the horizontal branch pipe 7 extended in parallel from the drainage header 6 has two support bands at the straight portion. The horizontal branch pipe support fitting A2 having 4 is inclined to support the horizontal branch pipe 7. As a result, even in the horizontal branch pipe support device of this example, it is possible to eliminate the need for additional support of the corner portion as described above, and to prevent dangers such as operator whispering as much as possible by reducing the protruding width. I can do it.

  These horizontal branch pipe support fittings 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 horizontal branch pipe support fittings in the field, and the base plate 1 is connected to the horizontal branch pipe 7 respectively. The base plate 1 is anchored to the concrete slab so as to be orthogonally arranged or inclined with respect to the base plate 1 or the base plate 1 is anchored, and then the upright bolts 2, the support plate 3 and the support band 4 are set on the base plate 1. The height of the support plate 3 is adjusted by vertically adjusting the positions of the nuts 31 of the standing upright bolts 2, the upper band piece 42 is rotated and opened, and the lower band piece 41 of the support band 4 is parallel to the drainage header 6. After placing the connected lateral branch pipe 7, the upper band piece 42 is turned and closed, and the upper fastening piece 46 and the lower fastening piece 4 and so as to secure fastening by hexagonal bolt 48 may be supporting the transverse branch pipe 7.

  The illustrated example is as described above. However, the support band of the horizontal branch pipe support fitting having the single support band can freely move both the horizontal angle and the slide in the longitudinal direction of the support plate. The central support band of the horizontal branch pipe support fitting having the support band can be freely set to both the horizontal angle and the slide in the longitudinal direction of the support plate, and conversely the horizontal angle and the support plate in the longitudinal direction of the support plate. When using the long holes of the support plate to make the support bands that can be freely slidable and horizontally slidable and to be slidable, the long holes are supported as a series. There is a situation in which the slanted arrangement of the horizontal branch pipe support bracket is hindered by the presence of, for example, pebbles of concrete slabs, etc. In carrying out the present invention, including supporting the horizontal branch pipe by arranging it at right angles to the horizontal branch pipe, including the time, the base plate, the standing bolt, Support plate, support band, drainage header, side branch pipe, downward bolts used as needed, through-holes through which the downward bolts are inserted, specific shapes such as long holes, structures, materials, relations between these, additions to these Can be in various forms as long as they do not contradict the gist of the invention.
