In present installations connec-tion between two aligned pipes is obtained using tubes wi~h one end enlarged in the form of a coupling whose internal diameter is greater than the ex-ternal diameter of said piDe and therefore of the second end.
Connection is thus made by inserting the ends of a pipe into the coupling-shaped e11ds of the other pipe.
The patent GB A 1282325 discloses a method of connection between pipes by means of elastic couplings.
These couplings avoid the 1lecessLty of having an enlarged end, make up for any irreg~llarities there may be in both Linear and angular installations, as well as ~or any var-iations in lengths of conn~cted pipes caused by changes in temperature, and ease adjustment of pipe lengths to suit dimensions in the building structure.
The installation realised ~ith the above patent does not, however, provide any advan1:age if pipes become clogged or damaged since, as happens ~ith such installations generally, it is still impossible to obtain easy replacement of any damaged parts or even of t~le whole system. ~ -A~/IEN~ED SHEET

Sub ject oE the invention is a drainage system for waste water in civil and industrial buiLdings with connections to sanitary equipment and to a main drain trap connècted to the ~raste stack comprising - a main drain trap collecting water from a lavatory bowl, - a first box-shaped trap collecting water from sanitary equipment, - a second box-shaped trap collecting water from a bath, shower and the like, - pipes interconnecting the drains of the sanitary equip-ment as welL as the second box-shaped trap with the first box-shaped trap, and pipes interconnecting the first box-shaped trap as ~reLI as the Lavatory bowl with the main drain trap.
The invented system is separated into two sub-systems,one inside the other.
The first sub-system comprises box-shaped traps and pipes definitively instaLled in the structure of the buiLding.
The second sub-system comprises box-shaped traps and pipes shaped simiLarly to th~se of the first sub-system within which they are placed.
The pipes of the first and second sub-systems are connected to fittings there where the pipes come out of the structure of tlle buiLding to connect to the drains or the flush pipe of the sanitary equipment, or to the main drain trap.
Said second sub-system, of a different size compared with the first one, has locking parts to permit easy instalLation inside the first sub-system and, in the event of breakages, quick and easy removaL and replacement of part or aLL of said second sub-system.
Said box-shaped traps, whether of the outer fixed or inner repLaceable sub-system, have orifices in their sides.

The orifices in the fixed box-shaped traps are aLigned with the orifices in the internal replaceable box-shaped traps and have fittings for the pipes and covers that lie flush with the external plane of the building structure. If ne-cessary, said covers are sunk to alLow space for a layer of top finishing materia~. the same as that already used.

W~ 95/20077 2 1 8 1 7 9 3 PCTIIT94/00066 The piping, of synthetic material, i9 flexible and has helical undulations that form external and internal thread-ing, pipes for the replaceable system being placed inside said fixed system.
5 Fittings on said traps, forming part of the fixed system, consist of external cylindrical pipe unions on the orifi-ces, having external threading corresponding to the in-ternal threading on the fixed pipes forming the fixed sys-tem to permit unions and pipes to be coupled toge~her.
Connections to the traps in the replaceable system consist of pipe unions inside their orifices, internal taper con-verging on the inside, with external threading on the out-side onto which a washer is to be~ screwed, said washer ha-ving a cylindrical axial body surrgunded by a head in which a cylindrical cavity is threaded with the same thread as that of the pipe unions.
Packing inside the pipe unions partially projects inwards in the box trap, its external taper corresponding to that of said orifices, and its internal diameter corresponding to the external diameter of the piping forming part of the replaceable system.
It follows that by screwing on the washer said packing, forced inside the pi~e union by the opposing tapers, holds the piping firmly against the axial body of the washer by means of its thread, so making a stable connection.
Fittings on the orifices, in the building structure, form-ing part of the fixed system, consist of a cylindrical coupling whose external thread is the same as the internal thread on the fixed pipes; said coupling is to be placed inside the structure and comprises a perforated head of greater diameter which makes contact with the external surface of said structure.
W0 95~20077 _ 4 _ PCI/IT94/00066 The pipe is in this way fixed to said coupling by the thread .
The hole in the above head is larger than the maximum diameter of the piping in the replaceable system to al-5 low said piping to emerge freely outside the buildings t ruc ture .
Alternatively the fittings on the orifices in the build-ing structure of the fixed system consist of an internal-ly threaded cylindrical coupling, said internal thread 10 being the same as the external thread on the fixed pi-ping; said coupling is placed inside the structure and is fitted with!a flange that makes contact with the ex-ternal surface of said structure.
In this way the fixed piping is connected to said coup-15 ling by means of its thread, while the piping in the re-placeable system freely emerges from the building structure.
Pipe fittings for the sanitary equipment - bath, wash basin, bidet and others - consist of a coupling fixed to the drainpipe union of said sanitary equipment, having 20 an external thread to receive a threaded lock ring and having one end whose external diameter corresponds to the smaller internal diameter of the piping in the replace-able system .
Inside said lock ring is a threaded hole by which said 25 ring can be screwed onto the couplin~; said hole ends in a flaired taper that houses packing with a correspond-ing taper on its outer surface, and an inner cylindrical hole whose diameter corresponds to the maximum diameter of the piping in the replaceable system.
30 The lock ring is externally threaded and to this is screwed a washer in which there is an axial hole through which the piping passes.
~ WO9S/20077 2 1 8 1 793 PCTIIT94/00066 Therefore, by 6crewing on said washer, the packing when forced inside the coupling, due to the opposing tapers, holds the piping firmly to the coupling and so makes a stable connection.
5 The fitting on the drain to the lavatory bowl consists of a ring nut whose internal thread corresponds to the external thread of the piping in the fixed system, with a flat flange to connect with the flooring, and of pack-ing in which there is a hole whose diameter corresponds 10 to the external diameter of the drain pipe union for said lavatory bowl, the maximum external diameter being greater than the internal diameter of the flange, and with an internal axial helical annular groove corres-ponding to the dimensions and shape of the piping in 15 the replaceable system.
It is therefore possible to fix the piping in the fixed system by screwing its external thread onto the thread of the ring nut, and to fix the piping in the replace-able system by fitting its end into the helical groove 20 in said packing.
The lavatory bowl drain pipe comprises an original part in which there are orifices which have an external thread corresponding to the internal thread on the piping in the replaceable sy6tem.
25 Said piping can therefore be fixed by screwing the thread on the fitting into t:he internal thread of said piping.
Said original part is connected to the upper part next to it by means of a concertina-type flexible connection so as to allow for aTIy change of shape in the lavatory 30 bowl drain pipe, as ~ell as to facilitate replacement of said original par~ .
W095/20077 21 8 1 793 pCT/lT94~00066 The drain traps for the bath or shower and for the other pieces of sanitary equipment have connections similar to those of the other box traps making connection possi-ble, by means of two orifices, onto the drain pipe of the S lavatory bowl and to the overflow pipe respectiveLy, while plugs to holes in the sanitary fittings are worked by a tie rod inside the piping that connects said box trap to the overflow.
The advantages of the invention are clear.
10 The fixed external system assumes the form of a simple "sheath" or Supparting structure for the replaceable sys-tem whose functions are equivalent to those of systems at present in use.
In the event of a breakage or blockage, not only is inspec-15 tion made quick and easy, but also damaged parts, or eventhe whole internal system, can be replaced.
This can be done without any damage to wall or floor finish-ing material which in this way are not sub jected to the slightest strain or stress.
20 In prefabricated buildings, the component parts of the fixed system in particular, can be installed during building.
The replaceable system can then be put in after the struc-tural parts have been given their permanent positions.
All this means considerable savings should repaires become 25 necessary, offering as well aesthetic advantages inconrei-vable with present systems, economy in overall costs since installations of the replaceable system, after masonry work has been completed, avoids damage and facilitates the wo rk .

Sub ject oE the invention is a drainage system for waste water in civil and industrial buiLdings with connections to sanitary equipment and to a main drain trap connècted to the ~raste stack comprising - a main drain trap collecting water from a lavatory bowl, - a first box-shaped trap collecting water from sanitary equipment, - a second box-shaped trap collecting water from a bath, shower and the like, - pipes interconnecting the drains of the sanitary equip-ment as welL as the second box-shaped trap with the first box-shaped trap, and pipes interconnecting the first box-shaped trap as ~reLI as the Lavatory bowl with the main drain trap.
The invented system is separated into two sub-systems,one inside the other.
The first sub-system comprises box-shaped traps and pipes definitively instaLled in the structure of the buiLding.
The second sub-system comprises box-shaped traps and pipes shaped simiLarly to th~se of the first sub-system within which they are placed.
The pipes of the first and second sub-systems are connected to fittings there where the pipes come out of the structure of tlle buiLding to connect to the drains or the flush pipe of the sanitary equipment, or to the main drain trap.
Said second sub-system, of a different size compared with the first one, has locking parts to permit easy instalLation inside the first sub-system and, in the event of breakages, quick and easy removaL and replacement of part or aLL of said second sub-system.
Said box-shaped traps, whether of the outer fixed or inner repLaceable sub-system, have orifices in their sides.

W~ 95/20077 2 1 8 1 7 9 3 PCTIIT94/00066 The piping, of synthetic material, i9 flexible and has helical undulations that form external and internal thread-ing, pipes for the replaceable system being placed inside said fixed system.
5 Fittings on said traps, forming part of the fixed system, consist of external cylindrical pipe unions on the orifi-ces, having external threading corresponding to the in-ternal threading on the fixed pipes forming the fixed sys-tem to permit unions and pipes to be coupled toge~her.
Connections to the traps in the replaceable system consist of pipe unions inside their orifices, internal taper con-verging on the inside, with external threading on the out-side onto which a washer is to be~ screwed, said washer ha-ving a cylindrical axial body surrgunded by a head in which a cylindrical cavity is threaded with the same thread as that of the pipe unions.
Packing inside the pipe unions partially projects inwards in the box trap, its external taper corresponding to that of said orifices, and its internal diameter corresponding to the external diameter of the piping forming part of the replaceable system.
It follows that by screwing on the washer said packing, forced inside the pi~e union by the opposing tapers, holds the piping firmly against the axial body of the washer by means of its thread, so making a stable connection.
Fittings on the orifices, in the building structure, form-ing part of the fixed system, consist of a cylindrical coupling whose external thread is the same as the internal thread on the fixed pipes; said coupling is to be placed inside the structure and comprises a perforated head of greater diameter which makes contact with the external surface of said structure.
W0 95~20077 _ 4 _ PCI/IT94/00066 The pipe is in this way fixed to said coupling by the thread .
The hole in the above head is larger than the maximum diameter of the piping in the replaceable system to al-5 low said piping to emerge freely outside the buildings t ruc ture .
Alternatively the fittings on the orifices in the build-ing structure of the fixed system consist of an internal-ly threaded cylindrical coupling, said internal thread 10 being the same as the external thread on the fixed pi-ping; said coupling is placed inside the structure and is fitted with!a flange that makes contact with the ex-ternal surface of said structure.
In this way the fixed piping is connected to said coup-15 ling by means of its thread, while the piping in the re-placeable system freely emerges from the building structure.
Pipe fittings for the sanitary equipment - bath, wash basin, bidet and others - consist of a coupling fixed to the drainpipe union of said sanitary equipment, having 20 an external thread to receive a threaded lock ring and having one end whose external diameter corresponds to the smaller internal diameter of the piping in the replace-able system .
Inside said lock ring is a threaded hole by which said 25 ring can be screwed onto the couplin~; said hole ends in a flaired taper that houses packing with a correspond-ing taper on its outer surface, and an inner cylindrical hole whose diameter corresponds to the maximum diameter of the piping in the replaceable system.
30 The lock ring is externally threaded and to this is screwed a washer in which there is an axial hole through which the piping passes.
~ WO9S/20077 2 1 8 1 793 PCTIIT94/00066 Therefore, by 6crewing on said washer, the packing when forced inside the coupling, due to the opposing tapers, holds the piping firmly to the coupling and so makes a stable connection.
5 The fitting on the drain to the lavatory bowl consists of a ring nut whose internal thread corresponds to the external thread of the piping in the fixed system, with a flat flange to connect with the flooring, and of pack-ing in which there is a hole whose diameter corresponds 10 to the external diameter of the drain pipe union for said lavatory bowl, the maximum external diameter being greater than the internal diameter of the flange, and with an internal axial helical annular groove corres-ponding to the dimensions and shape of the piping in 15 the replaceable system.
It is therefore possible to fix the piping in the fixed system by screwing its external thread onto the thread of the ring nut, and to fix the piping in the replace-able system by fitting its end into the helical groove 20 in said packing.
The lavatory bowl drain pipe comprises an original part in which there are orifices which have an external thread corresponding to the internal thread on the piping in the replaceable sy6tem.
25 Said piping can therefore be fixed by screwing the thread on the fitting into t:he internal thread of said piping.
Said original part is connected to the upper part next to it by means of a concertina-type flexible connection so as to allow for aTIy change of shape in the lavatory 30 bowl drain pipe, as ~ell as to facilitate replacement of said original par~ .
W095/20077 21 8 1 793 pCT/lT94~00066 The drain traps for the bath or shower and for the other pieces of sanitary equipment have connections similar to those of the other box traps making connection possi-ble, by means of two orifices, onto the drain pipe of the S lavatory bowl and to the overflow pipe respectiveLy, while plugs to holes in the sanitary fittings are worked by a tie rod inside the piping that connects said box trap to the overflow.
The advantages of the invention are clear.
10 The fixed external system assumes the form of a simple "sheath" or Supparting structure for the replaceable sys-tem whose functions are equivalent to those of systems at present in use.
In the event of a breakage or blockage, not only is inspec-15 tion made quick and easy, but also damaged parts, or eventhe whole internal system, can be replaced.
This can be done without any damage to wall or floor finish-ing material which in this way are not sub jected to the slightest strain or stress.
20 In prefabricated buildings, the component parts of the fixed system in particular, can be installed during building.
The replaceable system can then be put in after the struc-tural parts have been given their permanent positions.
All this means considerable savings should repaires become 25 necessary, offering as well aesthetic advantages inconrei-vable with present systems, economy in overall costs since installations of the replaceable system, after masonry work has been completed, avoids damage and facilitates the wo rk .
