First, the second-hand housing original strong electricity system
1. Old houses renovated many years ago. Generally, the electric lighting and sockets share a circuit. The wires are aluminum core wires or small-diameter copper core wires. Once the electrical appliances are opened in the same process, the total brakes will jump and cannot be used normally. ;
2. At the end of the 19th century, the state used to have a capacity increase in the old house. The general capacity is limited to the air conditioning circuit, which can basically be used. However, most of the capacity cable is used for cable trunking or direct use. The sheathed wire walks outside the wall, seriously affecting the aesthetic appearance of the decoration;
3, the old house's switchboard settings are generally old, and the power ratio is not reasonable, you need to reset.
Solution: Since the high-power electrical appliances used in modern home life are not affordable for the distribution system more than ten years ago, it is necessary to properly configure the old residential high-power system when renovating the old house: air conditioning Generally single-channel setting, single-channel lighting setting, single-loop setting of ordinary socket, kitchen bathroom socket as single-loop setting according to needs. In addition to the total circuit, the general old house is equipped with 5~7 power distribution circuits, which can basically meet the needs of the next ten years.
Second, the problem of water supply system in the reconstruction of old hydropower
The old galvanized pipe + the old valve can't keep the water, that is, it is not convenient to use it, and it must be replaced.
Solution: For the old iron pipe water supply, first remove the original pipe, and determine the new shower, wash basin, toilet, washing machine and sink. The location of the water supply. The fourth-generation PE-RT (heat-resistant polyethylene) home improvement tube is used instead of the original tube to solve the problem of water supply. For the replacement of the total control valve, it is necessary to greet the property company or the neighborhood committee in advance, and explain to the neighbors in the same building a water stop. The reason, under normal circumstances, everyone will understand, and then to change the total valve in the 9:30 to 4:00 hours, avoiding the peak season of cooking and other water.
Third, the problem of weak current system in the reconstruction of old hydropower
In the old house, usually the telephone, TV, and intercom are all wound outside the wall, and all need to be re-routed.
Solution: When renovating the old house, first ask the owner, in the future, you need to use the community broadband or install ADSL yourself, because the LAN connection methods of the two Internet access methods are not exactly the same, then determine where the router is placed inside the home, and access the Internet. Sharing problem solving: For the intercom system in the old house hydropower transformation, the general property is not managed very much, and some even do not have a property company. It is necessary to operate according to the specifications to ensure the sound or image is clear.
Fourth, solve the problem of cracking and cracking of the wall
In the old house, the phenomenon of cracking and cracking of the wall is not uncommon. Therefore, when the old house is renovated, the base layer of the wall needs to be treated. If it is simply painted, it is only a temporary solution.
Solution: Painting the wall surface is the key to the cracking and peeling of the wall of the old house. Therefore, when decorating the wall, we must pay attention to the basic treatment. Generally, the Chengdu decoration company is shovel the wall. After the flat, the interface agent will be applied, the interface agent has the function of preventing moisture, and can also play the role of protecting the latex paint. Next is the putty, the putty paste should use waterproof putty, the putty is generally scraped three times, and finally Brush the latex paint. If the wall wants to be painted with color, then the corresponding primer should be applied.
V. Anti-leakage problems in the reconstruction of old houses and hydropower
Because the waterproof layer of the bathroom and kitchen in the old house has been in disrepair, its anti-leakage effect is not as good as before. If you ignore this in the old house renovation process, it will bring some trouble to the owner's home life.
Solution: Before renovating the old house, the owner should first ask the decoration worker to conduct a closed water experiment on the bathroom and the kitchen to check how the waterproof treatment is done. The method is: block the floor drain, put 5 cm of water in the bathroom, observe for 24 hours, and then go to the neighbor's house to check. If there is no water leakage, it proves that the waterproof treatment is very good; if it leaks, the property must be re-waterproofed. After the treatment, after the waterproof treatment, wait until the ground is completely dry, then tiling, otherwise the ground will crack.
Sixth, increase the necessary switch socket
As people use more and more household appliances in modern home life, lighting and lighting equipment is becoming more and more abundant, so switches and sockets need to be set in many places in the home. Then, before the renovation, it is necessary to do the wiring work in advance, and what places need to be placed in the future, we must plan in advance, and the reserved switches and sockets of the old house are generally not enough. In general, a room must have at least 3 outlets, a set of two-bedroom homes with no fewer than 15 outlets, and no fewer than eight switches. The switch height of the same room should be the same. Generally, the switch should be 1.4 meters from the ground and the socket should be 0.3 meters from the ground. The switch of the hanging and living room should be set at the place where the owner can easily get it.
