LORO-X Rain Standpipes
They can really take it!
In modern façade architecture, LORO-X rain standpipes and rain downpipes are incorporated as construction elements. LORO-X rain standpipes and downpipes made of impact-resistant steel provide reliable protection against vandalism and accidents of all kinds.
LORO-X downpipes are available in various designs and materials. There is the right solution for every area of application.
The extensive range of fittings – bends, branches, transitions, adjustment pieces and special parts for particular areas – meets practically every installation requirement. To prevent icing in the downpipes, electric heating systems can be used.
Areas of application
Residential buildings, inside and outside industrial buildings, public buildings and multi-storey car parks – wherever downpipes in traffic areas must be protected against mechanical damage.
Advantages
- impact-resistant, frost-resistant, dimensionally stable, non-combustible
- standpipe and cleaning pipe in one piece
- easy to paint
- DN 50-150
- 0.5 to 3 metres long (depending on nominal size and material)
- easy connection to zinc sheet, PVC and LORO rain downpipes as well as to various types of underground pipes.
LORO-X Rain standpipes
to protect against vandalism and damage from people, objects and vehicles
LORO-X Rain standpipes made of steel offer optimal protection against vandalism and damage from people, objects and vehicles of all kinds. Damaged rainwater pipes impair the function of the roof drainage and lead to undesirable moisture in the masonry and facades in the long term.
In accordance with DIN EN 12056-3 7.5, cleaning openings must be provided at the end of downpipes and at changes of direction.
With the appropriate connectors, LORO-X rain standpipes can be connected to all common underground pipes.
Standards require rain standpipes
Downpipes on residential buildings, inside and outside of industrial buildings, on public buildings and in parking garages in the area of sidewalks and driveways are exposed to mechanical damage up to 3 m in height.
Damaged downpipes, on the other hand, impair the drainage function of the roof drainage and, in the long run, lead to unwanted moisture penetration of masonry and facades.
DIN 1986-100: 2008 (Section 6.1.4) requires: "For downpipes, pipes (standpipes) made of a suitable material are to be used in areas in which mechanical damage is to be expected."
LORO-X Rain Standpipes and downpipes: When quality and a long service life are required!
With cleaning opening
According to DIN EN 12056-3 7.5 for cleaning openings
LORO-X rain standpipes and rain downpipes are used as protection against mechanical damage to residential buildings, inside and outside of industrial buildings, public buildings, parking garages and in the area of pedestrian and traffic routes. Especially with all external downpipes from roof surfaces, roof terraces, canopies or balconies.
The removable cleaning cover of the cleaning opening enables access to the downpipe upwards and the underground pipe downwards.
DIN 1986-100: 2016-12 (Section 6.1.4) also requires: "For downpipes, pipes (standpipes) made of a suitable material are to be used in areas where mechanical damage is to be expected."
With spout bend
for downpipes with discharge to the outside
LORO-X standpipes with welded-on outlet bend are suitable for downpipes without an underground pipe connection that discharge into the open (downspout). A later "falling off" of the outlet bend due to the flow shooting down from above is ruled out. Any supporting structures for a separate bend are not required.
A regular application is emergency drainage into the open. But also - as is common in Scandinavian countries - when the main drainage discharges into the open, e.g. because there is no underground pipe.
Smaller nominal sizes from DN 50 are ideally suited for draining canopies, balconies, shelters and small areas. Larger nominal sizes up to DN 150 are particularly suitable for large areas and the "Scandinavian construction method".
According to DIN EN 12056-3 7.5, no additional cleaning opening is required for a free outlet onto open surfaces.
With HSÜ
Backflow prevention with high-performance safety overflow (HSÜ)
The new LORO-X rain standpipe with high-performance safety overflow (HSÜ) can be planned for every external downpipe in the new building or used for the renovation and retrofitting of existing downpipes.
The high drainage capacity of up to 9 l / s exceeds the planned drainage capacity of conventional DN 100 downpipes with gravity flow (4.5 l / s). It should be noted that “in front of” the HSÜ there is a sufficiently large “damage-free, freely floodable area”.
How it works: Normally, the water is routed past the HSÜ into the underground pipe. The inclined and pipe-like drainage openings (see detailed drawing, page 20), for which a patent has been applied for, normally prevents leakage. In the event of a backflow from the underground pipe, a standing water column builds up in the LORO-X rain standpipe, which builds up overpressure on the HSÜ and can therefore "push" large amounts of water through the HSÜ (see data sheet LX1390).
No emergency drainage function: The high-performance safety overflow on the downpipe of the main drainage offers reliable protection against backflow from the underground pipe, but does not replace emergency drainage, as there is no function in the event of blockages on the main drainage!
