Features of fastening by means of clamps. Using the
clamps When laying polymer materials, it is important that there is no tension in the pipeline. To fix the construction of sewage lines use a clamp for sewerage. Pipe clamp is a semicircular screed, which when connected together form a ring. This is very convenient, as it allows you to change the size for each segment of the communication separately. Fasteners should also be equipped with rubber gaskets, which correspond to the diameter. If there is no liner, you can use elements with smooth internal surfaces.
Types of clamps
There are two types of material: metal and plastic. The metal clamp will provide a reliable and durable connection. Using a plastic clamp, in turn, you can not only firmly fix the water pipe, but also fix it movably. Plastic fasteners also have a price advantage - it costs less than a metal equivalent.
When choosing between a plastic and metal clamp, one should not forget about the aesthetic side. This concerns, first of all, an open pipeline that does not hide the walls. Plastic fasteners in this case will be less noticeable.
When selecting the clamp, it should be taken into account that there are two types of fastening: rigid and floating. Sites where the collar tightens the channel are hard fixation points.
The task of rigid type of fastening is a strong fixation of the junction of pipeline sections and fittings.
The floating version of fixing is that the holder is not fully tightened: when the pipeline is already assembled, it remains mobile in the longitudinal direction. To do this, it is necessary that the diameter of the fastener exceeds a little the diameter of the piece on which it is fastened. This type of fastening is performed in order to ensure the integrity of the channel with possible deformations from temperature fluctuations.
Technology for fixing pipes on the wall
When preparing for installation, it is necessary to stock up in advance with all necessary materials: pipes, shaped sanitary fittings of the appropriate diameter, fixing clamps, brackets, supports, fasteners, and tools that will be required during fixing.
Pipe clamp is installed at a minimum distance from the wall. This will help preserve the useful area and reduce the risk of damage to the pipeline.
When installing, you need to remember a few important rules:
1) If you are laying a pipeline in a room where there is heating, you can avoid the possibility of temperature changes during operation. In this case, you can use static supports - rigid fastening. They need to be carried out in the places of branches and bends.
2) Floating bearings are used when there is a need to amortize the thermal expansion of the metal. The impact of different temperatures can act on the pipeline - it will shrink or expand. In doing so, you exclude the possibility that it will deviate from the highway.
Next stage - apply markings to the walls, it will act as an axis for fixing the pipes. Use for this purpose self-tapping screws or special dowel-nails, depending on what kind of walls you have. If necessary, make an indentation from the wall - use mounts. Now you can start to build communications.
Piping
There are two ways to securely fix the sewer. Everything depends on the specifics of the work, as well as the material from which the walls of the house are made.
One of the ways - closed laying. He assumes that the pipes will be fixed and laid in the thickness of walls and partitions. After the final stage of finishing sewer pipes will be invisible.
You can also use the method of open laying and fastening pipes. It is less versatile and less labor intensive, which is why it is used more often than the method of closed laying. Then the sewer pipes remain on the surface.
In addition to the mounting clamps, sound absorption is used in each of the above-described methods. They allow you to make quieter noise, which is produced by sewage.
Also, when laying sewer pipes, the material from which the walls are made should be taken into account.
Remember, right angles increase the possibility of blockages in communications. It is worthwhile to develop the project in advance and to repel the guides on the walls.
Brick wall
In the brick wall it is necessary to make a channel in order to avoid the internal stress of the pipeline. Where it can be affected by high temperatures, it should be isolated.
The segments, which will be laid horizontally in the communication communications with the connection of more than two wall lines simultaneously, should be provided along the entire length of the support.
Overlapping
When laying sewer pipes through floors, it is important to remember two conditions: water resistance and sound insulation. To do this, you should use the lining.
Concrete
During the installation of the pipeline in concrete structures, it is important not only to ensure quality fixation for sewage channels, but also to guarantee their thermal elongation. Elements of communications at the same time mounted so that during the concreting there are no displacements.
