The old house refers to the use of more than 10 years, especially the construction of multi-storey buildings before the 1990s, and houses that need to be renovated and reconstructed. Hydropower renovation is the core foundation project in the renovation of old houses, and whether the preparation work for hydropower design is directly related to whether or not the concealment project can be completed, directly affecting the comfort of future life. Today, Xiao Bian wants to tell everyone about the old house 's knowledge of hydropower reform . Interested friends come and see it!
The old house hydropower reform design principles
1, scientific design
Old house power line aging is serious, the original structure generally uses a fine copper core or even aluminum core wire, lighting outlet with the loop regardless of home, even if a few years ago had to go through the circuit transformation of the room is only a partial increase or decrease socket, not fundamental Changing the distribution system can not meet the needs of users. In the hydropower design process, professional hydropower designers can be asked to scientifically distribute distribution systems according to the needs of users' home appliances. Lighting, ordinary outlets, air conditioning outlets, kitchen and toilet outlets and other special appliances should be designed in sub-circuits (below), before and during construction. After completion of the design drawings must be complete.
2, practical weight
The old house has a large amount of hydropower renovation projects. Considering that the average old home is mostly 5(20)A meters, according to the demand, the family can normally use strong and weak electricity, and the water supply and drainage location can be designed in place. Avoid setting too many high-power electrical power supplies to cause current overloads that cannot be used. Excessively unusable extras can only increase the amount of work that results in idle waste. For example, a 2.5-meter-high building has a circle of spotlights for one year. Not two times. The old house's hydropower design must be sufficient and practical enough to effectively control the budget to save money.
3, safety first
Do not arbitrarily design the groove in the ground to walk the pipeline (even if there is backfill leveling layer), otherwise the vibration caused by the groove will destroy the decorative paint layer on the floor below the building, and may even affect the safety of the floor structure. The general design plan is to dismantle the old floor or brick, and then walk directly on the ground to clear the pipe and fix it. Then lay the tile directly or mix and level the mortar to lay the floor. Most of the old house's water supply pipes are rusted iron pipes that are not hygienic. They need to fundamentally abolish the original water pipes and replace them with polypropylene-buried plastic pipes; the water supply control valve is not closed tightly, and is likely to cause run water hazards. When the need to pay attention to the replacement of the valve; the old house to cast iron drainage pipe-based, distribution structure is very unreasonable, the need to re-design the distribution structure of the water pipe, the second transformation using PVC pipe and cast iron pipe joints must be better deal with, otherwise easy to seepage.
4, based on me
Hydroelectric design should be people-oriented. On the one hand, professional designers must not only possess professional knowledge but also need to have rich life experience to achieve humanized design. The mechanical implementation of the user's ideas and can not put forward independent opinions is not qualified; otherwise The important thing is that before and after the hydropower design needs to be well prepared, how the furniture is placed, how wide the bed is, whether it is an electric water heater or a gas water heater, etc. It needs to be considered well, and you may not know how to operate it, but you must know that you need to What is the effect, do not expect the designer to help you solve all the problems, quote a famous netizen to end this article: "Who lives, whoever wants to worry about it, or who has to worry."
How to perform immediate acceptance after water circuit construction
1. Water acceptance: After the water reformation is completed, the cold and hot water pipes have been reformed with a hose to ensure that the hot and cold water pipes of the entire indoor pipe are pressed at the same time; the pressure suppressor is installed, the pressure suppressor is filled with water, and the air in the pipe is let off, so that the entire circuit is inside. It is all water; close the water meter and the outside gate valve (make sure to protect it). Then began to suppress, the experimental value is 1.5 times the working pressure, 30 minutes impermeable, pressure drop does not exceed 0. 05MP is qualified
2. Strong power acceptance: Use 500V insulation resistance meter to test the insulation resistance value of each circuit, and at the same time, it can test the quality of the used wires. Wires that do not meet the standard may be broken down;
3. The weak current adopts the special tool test: The special network test tool tests whether the 8-core signal of the network is unimpeded; the carrier's copper shaft cable test tool, the multimeter and other complete tests are qualified before the next construction work.
4. It must be noted that the completion of the hydropower reform must be checked and accepted, and it will be too late to wait until the completion of the construction of other projects.
The above is an introduction to the relevant contents of the old house's hydropower reform and I hope to help you. For more information on hydropower reforms, please continue to pay attention to information on this site.
