If it is necessary to lay communications in public and residential buildings, an important point is the fastening to the pipe wall. Depending on which products are used, different types of mounts may be used. The latter differ structurally, in material and method of fixing in the wall.
The mounting method will depend not only on the pipes themselves, but also on the type of wall. The main types of pipes that are used in laying communications can be divided into the following categories: drainpipes and polypropylene pipes. The latter option is used for laying sewers and plumbing systems. They can vary in diameter, and clips and clamps are used for fixing.
If we are talking about drainpipes, then they are intended for the installation of drainage systems. They are made of metal or plastic, and fixing is carried out using special clamps. Metal pipes are used for the installation of water, gas and sewer systems. For their fastening, you can use clamps.
Preparation of tools and materials
If you will be attaching a drainpipe to a wall, then you need to stock up on some tools and materials. It:
- hammer;
- crosshead screwdriver;
- roulette;
- marker;
- drill;
- knife or scissors for cutting pipes;
- level.
Use of clamps
If it is necessary to carry out fastening to the pipe wall, then different clamps can be used for this, which can be plastic as well as metal. The first variety is used for the installation of sewers, drainage systems and polypropylene pipes. These elements are a support with a dowel, which is installed in the wall. To fix the pipe, a semicircle is used, which is connected to the supporting screw element.
Fastening to the pipe wall can be carried out using metal clamps, which are designed for pipes of the same material. Sometimes they are used for mounting systems made of plastic. These elements are a support with a shock anchor or dowel for mounting in the wall. Pipes are fixed with a semicircle on screw connections. According to the outer diameter of the pipe, there is a rubber ring inside the clamp, which is used to reduce noise and dampen vibration.
Using staples
Fastening to the pipe wall can be carried out not only by the above technology, but also using brackets. If the pipes will be used to equip the water supply system, then this technique can be used. This element is a support made of nylon, which is fixed with dowels to the wall. It is necessary to snap the pipe into it.
When laying the system, the brackets are distributed along the axis of the water supply, and the distance between them should be 50 cm. For their installation, markings are made on the wall, along which holes are made. After the brackets are installed in their places, and a pipe is laid on them. If we are talking about a sewer pipe, then metal or plastic clamps can be used for it.
More about fixing downpipes
Pipe clamps are used according to a certain method. If you purchase plastic pipes, then suitable clamps should come with them. To install them on the wall, you also first need to make markings, given that the first hole should be located under the water collector. The distance between the other mounts should be 50 cm or less. It is important to calculate the step between the fasteners so that there are two clamps per linear meter of pipe.
For gutters, it is necessary to use brackets that are attached to the windshield or rafters using self-tapping screws. When marking, it is necessary to take into account the slope of the drain, it should be 3 mm per linear meter. Some home masters think about what to choose - staples or pipe clamps. Staples are a cheaper method, but not as reliable. Therefore, quite often, metal pipes are fixed with clamps, which consist of a support installed in the wall with a dowel or anchor.
Using clips
Choosing a holder for plastic pipes, you may prefer clips that have high qualities of heat resistance and are resistant to mechanical stress. Among the technical characteristics, attention should be paid to the diameter, which should be equal to this indicator polypropylene pipe. How correctly the fasteners are installed will affect the life of the finished communication system.
If the clips are set too far apart, bending may occur in the places of the supports. When installing a communication system with pipes placed in parallel, a double clip should be used. It is important to know about the dependence of the distance between the clips on the temperature and the diameter of the pipe. Thus, if the pipe diameter is 16 mm and the temperature is 20 ° C, then the distance between the clips should be 75 cm. With the same pipe diameter and a temperature of 80 ° C, the distance should be reduced to 55 cm. When the diameter increases to 32 mm , and the temperature remains at 20 ° , then the distance between the clips should be made equal to 100 cm. The same pipe diameter and temperature of 70 ° require a distance of 75 cm to be observed. With a pipe diameter of 110 mm and a temperature of 40 ° the distance between the clips should be 175 cm, whereas if with the same diameter, the temperature increases to 70 ° C, the distance should be made equal to 140 cm. It is also important to remember that the bracket for attaching the pipe to the wall must be selected taking into account the external diameter of the installed system element.
Recommendations of specialists about the use of clamps
Fixing polypropylene pipes with clamps is carried out in cases where it is necessary to mount pipes of impressive diameter and with heavy weight. Using these elements, the pipe will be held firmly, and strong vibrations will be leveled. The bracket for attaching the pipe to the wall is supplied with the clamp, this fixation provides a rigid grip, which can be achieved by tightly tightening the clamp around the pipe. If the fastener should be floating, then between the clamp and the pipe should leave free space for the movement of the element. The mobility of the fasteners guarantees the possibility of expansion of the material during temperature fluctuations.
Conclusion
Before installing the pipe on the fixture in the wall, it is necessary to connect the elements together using polyfusion or butt welding, which is sometimes replaced by the method of electrical fitting. The holes for the dowel nails in the wall are made using a drill.
