Why do the embryo room and toilet sink 300?

For a long time, the toilet drainage of the house has been laid in the upper part of the lower room along the drainage pipe of the water appliance. With the commercialization of housing, this traditional laying method has obviously not adapted to the requirements of the times and development. The biggest problem is that the plumbing pipes are hoisted under the floor slabs.

Leaving the most problematic parts of the homes of other residents makes it necessary to set up suspended ceilings for the upper residents in the bathrooms of the lower floors, which can have a negative impact on the lower residents and sometimes even cause disputes in the neighborhood if the pipes leak or are blocked and need to be repaired. Secondly, the noise emitted by the upper floor residents when flushing at night also interferes with the lower floor residents. The traditional laying of toilet drainage pipes has become more and more obvious to contradict the concept of "people-oriented" housing.

Therefore, according to the basic principle that the pipeline must be laid on the floor of the household, after the designers continue to use various drainage methods, a newer water distribution method is obtained.

The so-called sunken toilet is that the bathroom structural plate descends to a certain height, generally not less than 300mm, and the descending part is filled with coke slag. There are two types of sunken toilets: one is that the toilet structural panels are all lowered, and the other is that the toilet structural panels are only lowered on the side of the sanitary appliances.

The advantages of a sunken toilet are:

1) The sunken drainage method makes the toilet because there is no drainage reserved hole for sanitary appliances on the floor, and the user can freely arrange the position of sanitary appliances to meet the personalized requirements of sanitary ware. The drainage pipes are arranged on the floor slabs and are backfilled with cushioning.

After covering, there is a better sound insulation effect, so that the drainage noise is greatly reduced.

2) In this drainage method, the sewage horizontal pipe is located in the sunken room, and the construction and future maintenance of the drainage pipeline do not affect the lower residents. At the same time, it can also effectively prevent the spread of germs.

Some rough room bathrooms need to drain their own water, to the basin, toilet, rain, and other floor drains, there is a high space for the homeowner to arrange by himself, so that the design can be arbitrarily arranged the layout of their own bathroom.

It refers to the partial or overall sinking of the structural layer of the toilet from a certain height (generally 40cm) of the corresponding floor during the construction of the main body, so that the horizontal drainage pipe of the toilet is buried in it, and then backfilled with lightweight materials, and the structural structure only needs to be set up with a hole for the use of drainage risers. Drainage risers are reliably set in the corners of the walls, and can be covered with external curved partitions when the owners decorate.

Code for Design of Building Water Supply and Drainage" (GB 50015-2003) "The sanitary appliance drainage pipe of the residential bathroom should not pass through the floor slab to enter other households", "Code for Residential Design" (GB 50069-1999) "The sewage drainage horizontal pipe of the residence should be located in the set of this floor", the drainage technology of the same floor is carried out on the same floor of the sanitary appliances due to the maintenance and overhaul of the pipeline, and does not interfere with the residents on the lower floor, while the traditional bathroom pipes are arranged horizontally and vertically, and they interfere with each other when they are maintained and used. It is inconvenient for people's lives.

Why do bathrooms have to be sunken? After the analysis, it dawned on me!

The kitchen has a sink?? I've done dozens of houses and I've never seen them.

You said that the washroom has caissons and it's okay.

The sinking is so that after the construction is completed, the restrooms are level with the outside floor. Under the floor of the restroom, there are 11 cm (4 inches) diameter sewage pipes, 9 cm diameter drainage pipes, and various water supply pipes.

If the toilet is not tens of centimeters lower. Then you have to go up two steps to the bathroom...

I. If you don't understand, you can answer patiently! ~

Professional plumbers, come here! ~！

Regarding bathroom waterproofing, 15 yuan is the market price of the decoration company, which is generally done by plasterers, and you can't ask people to deal with it so carefully. If you are really very demanding, you can log in to my company** to see the waterproof talk about the bathroom and the waterproof I recorded, like you are more delicate, you have to be shocked after reading it, hehe.

Subsidence means that the elevation of this floor slab is lower than the normal indoor elevation, and generally the 2 sides of the beam will be subsided, that is, the subsidence slab has 2 supports for beams. There is a detailed structure of the reinforcement at the junction with the slab. See 04G101-4 for details.

The overall construction, but the elevation of the floor is different, the beam and the plate are connected through the beam heightened, the lower bedroom is because the bathroom cushion practice is more, such as the upper and lower water pipes, and finally the bathroom and the living room surface height difference of 20mm is enough.

Good professional problem, decoration knows some, the construction is too professional, nothing can be done.

I remember that the teacher said that it takes at least 10 years to standardize and organize, 10 years to publish and correct, and at least 5 years to modify and correct problems, so the current specifications are generally old, and you can only consult engineer-level people about this problem.

Install squatting or toilet, need to be decided according to family members, bathroom structure, if there are elderly people at home then it is better to install a toilet, if there are many guests at home, you can consider using a squatting toilet. Nowadays, the bathroom floor of many houses is not sunken, and if a squatting toilet is installed, the ground must be raised, which is not very beautiful.

If you must move the toilet to another location, you can try to change the pipe directly, and it is easier to drill holes in the ground. But the renovation can not be too big, but also to discuss with the downstairs, if there is a ceiling downstairs then it is easier to operate.

If it is a sunken bathroom, this problem is very well solved, as long as you pay attention to the main sewer pipe less bending, if it is not sunken, you can only use the shifter in a small range, the effect is not very good. If it's a villa, it's casual. Because of the thickness and built-in problem of the squatting toilet, the ground has to be raised if it does not sink.

If it's a home, it's a toilet, and if it's a company, it's squatting

If you want to move the position, you need to buy a 90mm diameter PVC pipe, solid 90 pipe, which can be placed in the original pipe, so that the water leakage may be smaller.

I think you should first think about what you use, whether you use a squat or a toilet and then decide whether to change it, mainly depending on whether they are the right size.

First of all, try not to change it, because it is easy to block. If you really want to change it, then you need to raise the ground, that is, you need to build a step as high as the pipe and wrap the pipe inside.

Is it the renovation of your new house or the renovation of your old house? If the new house is decorated, the sunken bathroom does not need to consider the problem of sewerage, mainly considering the layout of sanitary ware, sewer positioning. Any toilet bowl that sinks will do.

The bathroom toilet that does not sink does not need to be raised, and the squatting toilet is needed. If it is not sinking, it is recommended not to change its water level!

If there is a sink in the bathroom, you can move the position and knock the floor off, if there is no sink it is very troublesome, you need to negotiate with the downstairs residents to open the floor slab and punch holes, the most important thing is to do a good job of waterproofing

Yes, agree. Your question is a declarative sentence.

With the progress of society and the improvement of people's living standards, the requirements of the Ministry of Housing and Urban-Rural Development and other construction departments for commercial housing have gradually improved. At the end of the nineties of the last century, the Ministry of Construction of the People's Republic of China regulated.

The requirements of caisson design must be implemented in the construction of toilets in commercial houses, which are reflected in the article in the "Residential Design Code" (GB50069-1999): "The drainage pipe of the residence should be located in the suite of this floor" and the "Design Code for Building Water Supply and Drainage" (GB50015-2003): "The sanitary appliance drainage pipe of the residential bathroom should not pass through the floor slab to enter other households".

It is a drop, and the general inside and outside height difference is only 10cm

Without a tarp, it is generally brushed flexible and waterproof, the ground is fully brushed, the bath area is 1100, and the non-bath area is 300, but it must be tiled, if the brick is not pasted, if the waterproof is scratched, the waterproof of your home is a white brush, and the downstairs or next door will also suffer.
