Rajni facilities, all kinds of construction facilities
One of the most important and vital parts of any building is its facilities, which actually provide the main infrastructure for the comfort and peace of the residents to live and work in the building. For this reason, when you want to build a building from scratch, the most important part which should be considered is the facilities, the facilities are divided into different subcategories such as heating, cooling, plumbing, air conditioning, electricity supply, telephone lines, gas supply and other parts, which are further discussed in this article about the facilities Rajni, we will provide you with comprehensive explanations about each one.
What is a mechanical installation?
The mechanical facilities of the building include a set of structures and equipment that provide the internal systems of the building in order to improve the comfort for the life and work of the residents.
If we remove the mechanical facilities from a building, Practically, that building has become uninhabitable and can be compared to a ruin. For this reason, various subcategories such as sanitary facilities, air conditioning, gas supply, fire fighting, sauna, swimming pool and jacuzzi have been designed in the mechanical facilities of buildings to ensure the longevity and survival of a building. In the continuation of this article, we will introduce all the mentioned sections.
sanitary facilities (water and sewage)
Drinking water piping
The main use of sanitary facilities in a building is to supply and distribute sanitary water for purposes such as drinking and washing. Drinking water enters the building through the municipal plumbing system, and after passing through the water meter, it is directed to the consumption parts inside the building with the help of internal piping. The consumption water is divided into two groups, hot and cold. Equipment such as wall or standing water heaters, wall or ground packages, and engine room systems are used to provide hot water in buildings.
Among the pipes that can be used to transport hot water produced in thermal equipment are CPVC, PEX and copper pipes, among which PEX or multilayer pipes are preferred due to many advantages such as Flexibility, unique resistance to heat, ease of installation, excellent quality and higher execution speed are known as the best pipes that can be used in the hot water piping system.
Sewerage piping
Sewage piping in the building should be done in such a way that the water used in the building is transferred to the municipal sewage system in the street with the help of gravity. For this reason, in case of unprincipled implementation of this system, there is a possibility of sewage materials getting stuck inside the pipes. The common methods of sewage piping in buildings are divided into two categories: floor sewage piping and under-ceiling piping, which are open According to the design of the building and the conditions of the location, one of these two methods is chosen for implementation in the building.
Gas supply facilities
The start of gas piping in buildings should be done after the completion of the Chinese wall stage and after completing the file and selecting the contractor. It is also necessary to implement it on the basis of expert and engineering science, because the smallest leak in the pipes and connections can cause irreparable damages.
The most important points during the implementation of urban gas supply facilities
1. Before starting the work, the design and map of the gas supply piping should be drawn on paper and the gas supply equipment should be prepared. The possible route can be chosen for the passage of gas pipes.
2. The path of gas pipes should not have any interference with the main structures of the building and other mechanical installations in order to avoid damage.
3. Common parts of the piping system The building's gas must be placed outside.
4. The gas piping route must be exposed and visible to people.
5. Using a gas valve for several consumers is dangerous, so each consumer must A gas valve should be connected. Gas piping should be designed in such a way that gas appliances are installed at least one meter from windows and curtains. The gas piping system should be designed in such a way that the gas pressure The inside of the pipes should be fixed from the outlet of the meter to the outlet of each gas valve.
