Abstract

The collar for a pipe (2) comprises two semi-cylindrical half shells (4,5) held together by bolts (13). The upper half shell (5) is fixed to a sleeve (7) connecting to a pipe diversion. The lower half shell (4) is fixed to a rectangular base plate (3) with a part extending at either side of the half shell axis (XX') in a plane parallel to it. The base plate and the lower half shell are made from a single piece (10). Each half shell has a shoulder (9,15) on either side the axis, with a length along this axis equal to the diversion sleeve diameter, which come into contact when the two half shells are assembled. The shoulders are each drilled with a single hole (8,12) in a plane perpendicular to the axis. These holes allow the passage of the connecting bolts. The bolt heads (16) are locked in rotation relative to the lower piece (10).

Description

SUPPORT COLLAR
OF PIPING
The present invention relates to a pipe support collar.

 The technical sector of the invention is the Danish one for the manufacture of pipe fittings for pressurized fluids.

 The main application of the invention is to be able to connect to flexible plastic or semi-rigid pipes placed on the ground, such as those used in the irrigation and watering of large areas of agricultural land, bypasses which can rise. vertically with respect to said ground.

 In fact, various collars known as pipe support are known, allowing such connections perpendicular to a continuous pipe without cutting the latter and which are fixed by two half-shells; these surround said pipe, on which they provide the seal and which is perched through one of the half-shells which carry a connection sleeve making it possible to then screw a bypass generally at 9O- relative to the axis of the supply line.

 Thus, a farmer for example, who has laid a watering and irrigation pipe in his field, can come to the site, by adding such collars of support, place different branches to ensure watering at specific locations.

 When it comes to diversions themselves placed on the ground, the existing devices meet the needs perfectly, but when the farmer wants to be able to fix sprinklers, which must be located for this between 1 meter and 2.50 meters of the ground, such support collars must be associated with support systems maintaining the verticality of the diversions with respect to the ground, which requires additional equipment annexed to the pipeline, and a fairly long installation of said collars. support can then be maintained when storing the pipeline on a reel until later use.

 The problem is to be able to have support collars to ensure the function defined above bypass, on the one hand by avoiding installing additional supports to ensure a verticality of the bypass, and other share by authorizing the retention in place of said fixing collars after dismantling of said branches for storage on a reel of the main pipe.

 A solution to the problem posed is a pipe support collar, comprising two half-shells in semi-cylinders of axis XX ', held together by connecting means: 1' a so-called upper is secured to a connection sleeve of a pipe branch, and the other so-called lower half-shell is integral with at least one sole, part of which extends at least on either side of the axis XX along a plane parallel to the latter, said sole and said lower half-shell being made in one piece.

 In a preferred embodiment, said sole is of rectangular shape, extending symmetrically on either side of the axis XX ', but in other embodiments, said sole can be of square, round shape, etc ...

 Another objective of the present invention is to be able to install said support collars fairly quickly, without requiring many connecting parts, while ensuring perfect sealing and maintenance on the pipeline, despite the presence of the weight of the bypass placed at the vertical of the collar with respect to the ground.

 Such an objective is achieved in the present invention, by the fact that each upper and lower half-shell has a shoulder extending on either side of the axis XX ', of length along this axis at least equal to the diameter bypass sleeve, coming into contact when said half-shells are assembled and cooperating with each other; the two said shoulders are preferably pierced each with a single orifice situated in the plane perpendicular to the axis XX 'and passing through the axis of the sleeve, which orifices allowing the passage of a connecting and fixing axis of said half shells between them.

 In a preferred embodiment, said fixing ts mayens are bolts passing through said shoulders and the head of which is locked in rotation relative to the lower part, allowing the nut to be tightened after mounting without requiring access under the sole. .

 The result is new piping support systems, responding to the problem posed and the above objectives, without having the drawbacks of the devices used to date, in particular by farmers.

 Indeed, said soles integrated into the collar reduce the number of parts, are simple to produce and easy to assemble with the half-shells carrying the branches; once the assembly is assembled on the pipe, the low size of such flanges allows the pipe to be rewound again on a reel, since in general, the branches are far enough apart from each other so as not to overlap, which allows the stacking of successive layers which are based on the lower part of said soles wound with the previous layer.

 During the subsequent course of the channeling on the concenae ground, said soles will naturally bear on said ground, and the associated branches can be connected directly to the desired location and vertically without any other means, the soles guaranteeing stability lateral of these.

 In addition, the arrangement of the lateral shoulders on either side of the axis of the pipe makes it possible to reduce the number of fixing parts such as the bolts defined procedure and described below, to two, each on each side and on the other side of the derivation, one for each shoulder: these indeed create lateral support planes with respect to these said bolts, ensuring the longitudinal holding and the stability along the 'axis XX', and therefore guarantee sealing the support collar along this axis; it is certain that there could be four fixing bolts instead of two, but this number is sufficient in the context of the present invention, which makes it possible to reduce the number of fixing parts and therefore their cost and their time of implementation.

 One could cite other advantages of the present invention, but those mentioned above already show it sufficiently to prove its novelty and its interest.

 The description and the figures below represent exemplary embodiments of the invention, but are in no way limiting: other embodiments are possible within the scope and scope of the present invention.

 Figure 1 is a sectional view along I / I 'of Figure 3, of a support collar according to the invention.

 FIG. 2 is a sectional view along the same plane as FIG. 1 for an upper half-shell of a collar for handling a pipe with a diameter greater than that shown in FIG. 1.

 FIG. 3 is a partial top view of a support collar according to FIG. 1.

 Figure 4 is a sectional view along IV / IV 'of Figure 5, of an upper half-shell of a support collar according to the invention.

 FIG. 5 is a top view of an upper half-shell, shown in FIGS. 2 and 4.

The collar 1 for handling a pipe 2 which can be of any standard diameter, comprises, in a known manner, two half-shells 4, 5 in half-cylinder of axis XX ', held together by means 13 of connection: 1 'a so-called upper 5, is integral with a sleeve 7 for connecting a pipe branch, of which the' YY axis' is generally perpendicular to the axis
XX 'of the main pipe 2 and on which we want to ensure said connection; it must be possible to dismantle it when an entire pipeline device is used for irrigation or watering, as indicated in this main application, and which is generally seasonal; the pipes are then stored between the seasons of use and then put back in place: we want to be able then without operation or other device to find the vertical orientation of the branches during the next installation and in the right places.

 For this, according to the present invention, the other half-shell 4 of said collar 1 for taking care of the pipe 2, called the bottom, is secured to at least one sole 3, a part of which extends at least on both sides and d 'other of the axis XX' along a plane parallel to it, or in fact along the ground plane on which said pipe 2 is laid; said sole 3 and the lower half-shell 4 are made in one piece 10, such as for example molded plastic in a single manufacturing operation.

 Likewise, the so-called upper half-shell 5, as well as the shoulders defined above and described below, is produced in a single molded part 6, which is therefore assembled and removable with respect to the other lower part 10.

 As shown in FIG. 3, said sole 3 is preferably of rectangular shape extending symmetrically on either side of the axis XX ', said rectangular shape being in fact pseudo-rectangular, since s' refining slightly towards the ends: the main thing is to ensure stability along the directions of axis ZZ 'perpendicular to the axis XX' in the plane of said flanges which is the plane of the ground, on which we want to laterally stabilize said pipe and ensure the verticality of the axis YY 'of the bypass.

 The length along the axis ZZ 'of said sole rectangle 3 is therefore to be determined according to the height and the weight of the branch which is plugged into the sleeve 7.

It is also necessary to ensure the sealing stability of said support collar 1 in the direction
XX ', for which the overall stability of the branch itself is ensured by the length of the pipe 4 itself, but whose sealing on this pipe 4 must be maintained in the collar 1 itself. for this, each upper 5 and lower half-shell 4 according to the invention, carries a shoulder 9, 15 on either side of the axis XX 'and of length along this axis at least equal to the diameter of said sleeve 7 of bypass and coming into contact during the assembly of said half-shells and cooperating with each other by contact at least with their outer edges.

 The two said shoulders, respectively 9, 15 of the upper half-shell 5 and of the lower half-shell 4, are each pierced with a single orifice 8, 12 respectively, located in the plane perpendicular to the axis XX 'and passing through the axis of the sleeve 7, which orifices allowing the passage of an axis 13 of connection and fixing between said half-shells; these connecting pins 13 are preferably bolts, the head 16 of which is locked in rotation relative to the lower part 10, ie under said flanges 3, the nuts then being able to be mounted on the upper half-shell, once the pipe is set up during the first installation; or in fact in a reverse manner to that shown in FIG. 1, where it is a nut 16 which is represented under said flanges 3.

 Said lower part 10 is produced as indicated preccdenirt, in one piece, and is preferably hollow to limit the weight and reduce its manufacturing cost, but comprises to ensure its rigidity, so-called longitudinal partitions 141 perpendicular to the axis XX ', including in particular peripheral walls and a central partition, and inclined partitions 142 relative to said longitudinal partitions 141 which connect these inclined partitions 142 intersect at least in the axis of the connecting means 13; The set of planes containing said partitions 14 are perpendicular to said sole plane 3.

All of these partitions 14 are covered and connected to each other at their upper part by a continuous envelope 17, constituting in particular in the central part, said shoulders 15, as well as the lower half-shell 4.

 The upper half-shell 6 can also be produced at its lateral shoulders 9, partly hollow with two peripheral walls surrounding said lateral hollow parts, and median partitions in each of these hollow parts surrounding the parking lots 8 to reinforce the zones of link on which said fixing bolts 13 bear.

 FIG. 3 is a top view of said lower part 10, in which said partitions 14 are shown in dotted lines in the middle part III / III ′ as also mentioned in the section of FIG. 1.

 Said part 10 can also be either of slight shape between and concave towards the ground, as shown in section in FIG. 1, but it could also be flat.
