Description
DRAIN FOR SYSTEMS FOR EVACUATING PRECIPITATION WATER FROM WATERTIGHT INGS
* * * * *
The present invention concerns the field of the systems for evacuating meteoric water usually associated to terraces, terraced roofs and similar waterproofing pavement surfaces.
More in detail, it concerns an exhaust outlet, that may be integrated with said systems, arranged for allowing the normal discharge of flowing rainwater from the pavements of above mentioned waterproofing coverings and, at the same time, the drainage of any infiltrated rainwater.
It is well known that, for preventing the stagnation of rainwater on the waterproofing pavements of terraces, terraced roofs and similar places, usually a special system is associated thereto for the evacuating meteoric water, comprising a plurality of exhaust outlets communicating with a network of clearing outlets in turn connected to the gutters or to the rainwater discharges of the building.
In is furthermore known that, besides from the efficiency of said systems, the apparition of slits or capillary cracks on the surface of the pavements of above mentioned places, due to the action of atmospheric agents and of temperature change on the same, favours the leaking of infiltrating rainwater through said pavements, and through the relative resting block, and consequently the stagnation of said rainwater on the waterproofing sheathings for the protection of the floors underneath.
It is also known that said infiltrations carry along residuals of the materials they pass through thus causing, on the surface of said waterproofing sheathings, the formation of cement limestone deposits which, with their progressive volume increase, are able to
produce a proportional rising of the block above and, consequently, to determine the damaging of the pavement placed thereon.
If said deposits are formed near the drainage outlets of the evacuation system of rainwater associated to above mentioned places, the rising of the block may cause, in addition to the damage to the pavements, the detachment of said drainage outlets from the corresponding clearing pipes as well, and thus determine the malfunctioning of that part of system connected thereto.
The detachment of above mentioned elements furthermore allows said infiltrated rainwater to directly spill into the clearing pipes of the system, causing the progressive occlusion thereof due to the cement limestone deposited on the walls of the same, and consequently the functional block of the part of the system related thereto.
It is the aim of the present invention to overcome above mentioned problems.
It is the aim of the present invention to realize a discharge outlet placed between the drainage grids and the clearing pipes of a system for evacuating meteoric water, of the kind usually associated to terraces, terraced roofs and similar waterproofing coverings, which may allow the discharge of flowing rainwater from the pavements of said surfaces and, at the same time, the drainage of any infiltrated rainwater stagnating on the waterproofing sheathings for the protection of the floors of said coverings.
The aim set forth is reached by an exhaust outlet for systems for evacuating meteoric water from waterproofing coverings, characterized in that it comprises:
- a clamping plate arranged for allowing interposition of said exhaust outlet between drainage grids and clearing pipes of a system for evacuating meteoric water, of the kind usually
associated to terraces, terraced roofs and similar waterproofing coverings;
- a first pipe and a second pipe reciprocally connected in Y- shape and integral with said clamping plate, wherein said first pipe allows the discharge of flowing rainwater from the pavements of above mentioned coverings, and said second pipe allows the contemporary drainage of any infiltrated rainwater stagnating on the waterproofing sheathings for the protection of the floors of said coverings.
The present invention has the following advantages:
- it prevents the stagnation of infiltrated rainwater on the waterproofing sheathings for the protection of the floors of terraces, terraced roofs and similar waterproofing coverings, and consequently the formation of cement limestone deposits on the surface of said coverings;
- it avoids the damaging of the pavements of above mentioned coverings due to the rising of the relative resting block caused by the progressive volume increase of said limestone deposits;
- it avoids the damaging of the system for evacuating meteoric water associated to above mentioned coverings, due to the detachment of the drainage outlets from the corresponding clearing pipes, also due to the progressive volume increase of said limestone deposits;
- it avoids the occlusion of the clearing pipes of the system for evacuating meteoric water associated to above mentioned coverings, due to the formation of said cement limestone deposits onto the inner walls of said pipes;
- it reduces the costs of maintenance and/or repair operations of the pavements of above mentioned coverings and of the system for evacuating meteoric water associated to the same.
The advantages of the invention shall appear more clearly from the following description of preferred embodiments, made by way of an indicative and non-limiting example, with reference to the figures. Figures 1 and 2 respectively show, in a complete axonometric view and in an exploded view, the structural shape of an exhaust outlet for systems for evacuating meteoric water according to the present invention.
Figure 3 shows a vertical section of an example of installation of the same.
Figure 4 shows a complete axonometric view of the structural shape of a possible shape variant of the exhaust outlet according to the preceding figures.
Figure 5 shows, in a plane vertical section, an example of installation according to said variant.
With reference to the details shown in figures 1 , 2, 3, said exhaust outlet mainly consists of:
- a clamping plate 1 that may be applied by welding or gluing to the surface of the floors S of terraces, terraced roofs and similar places, arranged for allowing the interposition of said discharge outlet between the drainage pipes G and the clearing pipes CS of a system for evacuating meteoric water associated to above mentioned coverings;
- a first pipe 2 and a second pipe 3, reciprocally connected in Y- shape and integral with said clamping plate 1 , wherein said first pipe 2 determines the discharge of flowing rainwater from the pavement P of above mentioned coverings, and said second pipe 3 determines the contemporary drainage of the
infiltrated rainwater stagnating on waterproofing sheathings IP for the protection of said floors S, by leading said water towards the clearing pipes CS of said system;
- a tubular joint 4 arranged for connecting the single drainage grids G, placed on the pavement P and passing through the resting block M underneath, with the first pipe 2 of the exhaust outlet corresponding to said grids, and consequently with the clearing pipe CS connected to the same;
- a flat structure 5 arranged for supporting said tubular joint 4;
- a double order of dot-like or lamellar spacers 6, placed in discontinuous order along the lower border of the flat structure 5, arranged for allowing the resting of the same onto clamping plate 1 so as to determine the formation - between said flat structure 5 and said clamping plate 1 - of a special hollow gap 7 arranged for allowing the discharge of any infiltrated rainwater stagnating on the waterproofing sheathings IP of the floors S, towards the second pipe 3 of the exhaust outlet.
According to the present invention, the clamping plate 1 of each single exhaust outlet is secured by welding or gluing to the surface of the floors S of terraces, terraced roofs and similar coverings, and connected with waterproofing sheathings IP for the protection of said coverings, so as to determine the formation of a continuous structure which, without interruption, prevents the passage of any infiltrated rainwater towards said floors S and, at the same time, allows the stable positioning of the lower end of the first pipe 2 of the single exhaust outlets inside clearing pipes CS of the system for evacuating meteoric water associated to above mentioned coverings.
Furthermore, the first pipe 2 of each single exhaust outlet is connected by means of a special tubular joint 4, to one of the drainage grids G on the pavement P of above mentioned coverings,
so as to determine the connection thereof with the clearing pipe CS connected thereto.
The tubular joint 4 is supported by a flat structure 5 provided with a double order of dot-like or lamellar spacers 6, arranged in discontinuous order along the lower border of said structure, arranged for allowing the rest thereof onto said clamping plate 1 , determining at the same time the formation of a special hollow gap 7 between said flat structure 5 and said clamping plate 1.
As a consequence, when it rains, the flowing rainwater on pavement P are collected, as usual, by drainage grids G and, by means of tubular joints 4, they are first led into the first pipe 2 of the single outlets, and then spilled into clearing pipes CS, which convey them towards the gutters or the rainwater discharges of the building.
Instead, the infiltrated rainwater that might stagnate onto the waterproofing sheathings IP of said floors S, is led towards the exhaust outlets by means of appropriate inclinations given to the floors in the construction phase, so as to determine the flowing thereof, through suitable spacers 6, into said hollow gaps 7 contained between the clamping plates 1 and the flat surfaces 5 above.
Said water is then collected by the second pipe 3 of the single outlets, open on the relative clamping plate 1 , and by means of the first pipe 2, connected thereto in Y-shape, it is spilled into the clearing pipes CS for being conveyed to the gutters or the rainwater discharges of the building.
Figures 4 and 5 show a shape variant of said outlets having the purpose of fitting them to the different kinds of existing systems for evacuating meteoric water.
Said embodiment comprises a clamping plate 8, having an angular shape, carrying the first pipe 2 and the second pipe 3, which may be applied by welding or gluing to the surface of floors S and, at the
same time, to .the lower part of the masonry nearby the same; furthermore, it may be connected to waterproofing sheathings IP for the protection of said floors.
Said clamping plate 8 allows the installation of said exhaust outlets in horizontal position so that, due to an adequate inclination given in the construction phase to floors S and to the pavement P above, the first pipe 2 may allow the discharge of flowing rainwater - operating like a common overflow vent - from said pavements P, while second pipe 3 may allow the drainage of infiltrated rainwater transversally flowing through block M.
The collected rainwater is spilled in clearing pipes CS, which in this case are connected to the second pipe 3 of the single outlets, for finally conveying the rainwater towards the gutters or the rainwater discharge of the building.
Above described exhaust outlets are made out of synthetic materials like bituminous membranes, rubber, plastic PVC, stiff neoprene and other materials.
