Description

A kind of outdoor drop plate 50-80mm, floor heating does not drop plate 3L water Homofloor drainage system

Technical field

A kind of outdoor drop plate 50-80mm of the utility model, there is floor heating not drop plate 3L water Homofloor drainage system, belong to same layer row Water technical field.

Background technique

As commerical residence privatization is accelerated, the residential building number of plies is higher and higher, and people are also continuous to the environmental requirement of inhabitation It improves, decoration degree is more and more superior, and traditional construction method does not just catch up with society need.As brick mix structure is changed to cement casting Bar construction, shockproof grade will reach eight grades.Interlayer draining runs, emits, blocking up, leaking, is smelly, and toilet head room is inadequate, shower spraying Head is oblique spray head, and very inconvenient, there are the contradictions such as leak by upper and lower level resident, or even therefore to telling law court.

It is proposed in standard GB/T 50015-2003.4.3.8 items in 2003, the fixture drain of residence toilet The unsuitable passing through floors in road enter his family, this is just started the epoch of co-layer draining, and the drainage pipeline of sanitary apparatus is mounted on this layer and fills out In layer.

Traditional co-layer draining, structural slab reduces 350mm-450mm, in addition decorative layer 50mm, is exactly 400mm-500mm, It being just equal to dig a hollow place on structural slab, traditional water-drainage tube part is embedded in the inside, next layer can't see dewatering horizontal tube, But toilet runs, emits, blocking up, leaking, is smelly, problem of water saving is not solved, and increases cost instead (backfill amount is big).

It is well known that toilet drainage is to form gravity and the smooth draining of drainage pipeline gradient ability, same layer by drop Floor drain is core technology, and single channel floor drain is arranged in side and multifunctional floor drain is arranged in side, is only the dedicated floor drain of co-layer draining, and solve Following point:

One, smelly, water seal depth >=50mm, and double water seals, Double stink are solved, has the function of automatic replacing water seal water Can, it is automatically replenished water seal water function, nobody also has water seal in 90 days families.

Two, solve stifled, trap is not installed in entire toilet, is straight tube installation (not smelly to be solved by floor drain).

Three, it is difficult to solve maintenance, floor drain can all be dismantled, be a clearing device, be exactly access hole.

Four, it solves drop plate amount, is minimized degree, drop plate amount 200mm, greatly reduce backfill amount, reduce main body load Amount, it is often more important that, lower layer toilet head room 250mm is improved, it is how convenient that mountable 90 ° of spray heads, which are had a bath,.

This achievement fully demonstrate on June 1st, 2013 publish national standard atlas GB12S306 " residence toilet is same Layer draining " page 20,21,44,45,76,77,96.

Five, the pre-buried water accumulation part reason of co-layer draining solves leak, leak not instead of pipeline leak itself, pipeline configuration plate Surrounding leak, Pipe installing is all bell and spigot, with a slope, and it is not have in drainage pipeline that the gradient, which is more than or equal to 6/1000ths, Water, and install and do what leakage was checked and accepted, is also mounted in packing course, not will receive external force and destroys pipeline, but packing course Ponding passes through surrounding when structural slab seals by pipeline and generates dry and cracked seam, waterproof layer is destroyed, just toward lower layer's leak.In order to solve Leak, as long as pipeline passes through structural slab, the place of wall uses built-in fitting, and pre-buried ponding processor solves, by cement itself Extruding makes pre-embedded device firmly stick together, and will not generate dry and cracked seam, will not destroy waterproof layer, have ponding to pass through ponding in time Processor exhausts, so water, leak would not be emitted.

Six, noise is solved, installation eddy flow inserts formula threeway in draining to blowdown standpipe, and eddy flow inspection hole makes water be close to pipe Wall increases air column in pipeline, and draining rapidly, not will form sheet, forms mutually collision.

Seven, water-saving, country promotes flushing dose 6L/ times, could calculate energy-conserving product.

It is equally known that once flushing process is: water is gone out just object from closet (closestool), into dewatering horizontal tube, uses water The just object that suspends enters blowdown standpipe, and closet (closestool) can also clean water seal closet (closestool) discharge outlet, water seal depth >= 50mm is just calculated and is completed a flushing process.

So water-saving must have two conditions: one is water-saving type closestool, and one is that drainpipe laying is reasonable, and the two lacks One can not, 3L water closestool solves the above problem, it is necessary to have the laying of drainage pipeline reasonable, straight tube is more, and bend is few, pipeline It is short, the big formation gravity drainage system of drop.
