Abstract

Device consisting of a stage rod 1, a hooking system 2, other pipes C1, C2 on the stage rod 1, which serves as a supporting mast, and a filling device 3 of the passage of pipes through a slab 4.

Description

The present invention relates to a device for

  pipeline, for construction buildings.

  The present invention relates more particularly to a cast iron pipe device for the evacuation of waste water. Devices of this type are usually made from cast iron pipes with male ends and interlocking which are fixed to the walls of a sheath by

fixing collars.

  Thus, if several pipes pass through the same sheath, each pipe is fixed to the walls of the latter

independently of the others.

  Likewise, the various hot and cold water distribution networks present in the duct are also fixed.

  separately on the walls thereof.

  The problems posed by this type of pipeline are mainly related to considerations of space and

ease of installation.

  Indeed, each pipe having to be fixed to the walls of the sheath, the compactness of a sheath containing several pipes, which represents the general case, cannot be optimized. In addition, the need to attach each hose to the

  walls of the sheath causes a significant exposure time.

  The present invention therefore aims to provide a device which allows to obtain an optimum compactness of the pipe network present in a sheath and which avoids

  have to fix all the pipes to the walls of this sheath.

  - The present invention therefore relates to a channeling device for a building construction, consisting of water drainage pipes and hot or cold water supply pipes in which, on each floor of the construction building, a mast carrier, or storey rod, consists of a cast iron pipe, waste water discharge, additional equipment, such as clamps or rails, ensuring the attachment of other

pipes on the carrying mast.

  The present invention will be better understood on

  reading of the description which will follow, made with reference

  in the appended drawings, given solely by way of nonlimiting example, and among which: - FIG. 1 represents a schematic view of the device according to the invention, - FIG. 2 shows the connection of a cast iron pipe and a panty constituting a stage rod of the device according to the invention, - FIG. 3 shows a variant of the connection shown in FIG. 2, - Fig. 4 shows a device fixing collar

according to the invention.

  As illustrated in Fig. 1, the device which is the subject of the present invention consists of a stage rod 1, a fastening system 2, other conduits C1, C2 on the stage rod 1, which serves as a support mat, and a plugging device 3 for the passage of the pipes through a

slab 4.

  The stage rod 1 is formed, as illustrated in FIG. 2, a cast iron pipe 5 of axis X-X and a panty 6

  welded to the pipe 5 by means of an adhesive 7.

  In the embodiment shown in FIG. 2, the pipe 5 has at its upper end a socket 8 in which is housed the base of the pants 6, the glue 7 being interposed between the external surface of the pants 6 and the internal surface of the socket 8 of the

hose 5.

  However, other methods of attachment are possible, such as for example a sheet metal sleeve 9 which covers the upper plain end of the pipe 5 and the lower end of pants 6 with interposition between the sleeve and each plain end of a glue 7. This embodiment is illustrated

Fig. 3.

  The cast iron pipe 5 is precut and glued at the factory to present the exact length between two slabs 4 of

two successive floors.

  The pants 6 consists of a tubular body 10 of axis X-X extended at its upper end by a socket 11, a tube 12, without socket, is

connecting to the tubular body 10.

  As illustrated in Fig. 1, the attachment system 2 consists of collars 13, fixed to the stage rod 1, and collars 14, fixed to the pipes C1, C2 & hang,

connected by rails 15.

  As illustrated in Fig. 4, the collar 13 consists of

  two elements 13a and 13b of generally semi-circular shape.

  One end of each element 13a, 13b is extended by a lug 16a, 16b which extends in the external radial direction, each of the lugs 16a, 16b being provided with a hole through which passes a screw 17 on which is screwed

a nut 18.

  The other end of the element 13a is connected to

  the other end of the element 13b by a hinge 19.

  The central part of the element 13a has a protuberance 20a in the shape of a U, a flat outer face 25 of which is intended to be fixed on a rail 15. According to a variant, the element 13b also has a prominence

  b allowing the attachment of a second rail 15.

  Each rail 15 is perforated with holes over its entire length, which makes it possible to fix either other bypass rails 15 or different fixing collars 14 of the

conduits C1, C2.

  As illustrated in Fig.4 the filling device 3 consists of a floor 21 fixed to a metal frame 22 itself fixed to the underside of the slab 4 by

fixing hooks 23.

  The floor 21 has the openings necessary for

  passage of the pipes C1, C2 and of the stage rod 1.

  As illustrated in Fig. 1, the male end situated at the lower end of a stage rod 1 penetrates into the socket 11 of the pants 6 of the stage rod 1 situated on the lower stage, a lining d seal 24 being interposed between the socket 11 of the pants 6 and the male end. Once a storey rod 1 is in place, the filling device 3 having been fixed to the slab 4, concrete is poured into the formwork formed by the hole provided

in slab 4 and floor 1.

  Thus, the storey rod 1, and the conduits C1, C2, are rigidly fixed relative to the building, no

movement is no longer possible.

  In this way, if, during the assembly of the storey rods, it has been taken the precaution not to push the male end of a storey rod 1 to the bottom of the socket 11 of the pants 6 of the floor rod 1 located on the lower floor, there is perfect sound insulation. In fact, there is no longer

  of contact between two rods of successive stages.

  The present device therefore makes it possible, by centering the pipes around the supporting mast and thereby making the sheath

  more compact, to free up living space.

  Furthermore, this device reduces the exposure time

  and removes any fixation on the walls of the sheath.
