Recently, Master Tu, a house inspector on the Internet, discovered a lot of problems during the recent inspection of a finely decorated house in Xi'an! Air heating Exhaust pipes are not connected externally, floor drains and sewer pipes are in short supply and misaligned, wall tiles are hollow...
Nowadays, it costs a lot to buy a new fully decorated house, so naturally you want to buy a satisfactory house. And this is also a goal for many people, buying a house! But when it’s time to close the house after buying a new house, you find so many problems, which is a headache!
The air heater exhaust pipe is not connected externally: The air heater exhaust pipe is not connected externally, which is also a common problem in the inspection of finely decorated houses. If the air heater exhaust pipe is not connected externally, the ventilation function of the air heater will be affected or even counterproductive, so The exhaust pipe should be opened and extended to the outdoors so that the dirty air in the room can be discharged to the outdoors; when we use the bathroom fan heater, we need to turn on the exhaust function. When taking a shower, the space is closed and the air cannot circulate. Within a certain period of time, the temperature rises quickly and the room is relatively stuffy. It is easy to become hypoxic over time. Only by correctly connecting external pipelines can the air heating and ventilation function be used normally and avoid hypoxia.
Floor drain and sewer pipes are in short supply and misaligned: "Quality Acceptance Code for Residential Interior Decoration and Renovation Projects" JGJ/T304-2013 17.2.5 The installation of the floor drain should be straight and firm, and should be lower than the drainage surface without leakage. If it is not effectively rectified, firstly, it will affect the use of the special anti-odor floor drain core, and it will not play the role of anti-odor and anti-virus. Second, the misaligned part is the mortar layer, and drainage will penetrate into the mortar layer, which will have a certain impact on later waterproofing. Over time, the ceramic tiles will become more likely to hollow out.
Hidden dangers of incorrect connection of power phase zero: Although incorrect connection does not affect the use of electrical appliances, there are hidden dangers for the safe use of electricity . Mainly the control switch of some home appliances is used to control the live wire. If the live wire and the neutral wire at the socket are connected reversely, the control switch of the home appliance will control the neutral wire. That is to say, when the switch of a home appliance is turned off, the inside of the appliance is charged, which will affect the service life of the home appliance;
There are many leaks in sewer pipes. If long-term leakage is not treated, it is easy to get damp and fester. Warping affects the beauty of home decoration. Homes will also be filled with odors, affecting people's lives. Later, they may even attract cockroaches and rats, which can spread diseases.
Wall cracking: Cracks not only seriously affect the appearance, but will also fall off due to gravity over time, which also poses certain safety risks to people. Wall cracking is generally divided into 1. Structural cracking: Overloading of load-bearing structures will lead to structural cracking of the wall. 2. Shrinkage cracking: Because the materials are different, the thermal expansion and contraction coefficients are different, and no anti-cracking measures are taken at the junction of the walls. 3. Quality problems such as hollowing and cracking on the wall caused by construction technology and materials, low technical level of personnel, and tight deadlines
Wall tile hollowing: Ceramic tile hollowing is a common problem in the inspection of finely decorated houses, but the entire wall of ceramic tiles It is also relatively rare to be completely empty. Hollow tiles will cause the tiles to warp and fall off. There are certain safety hazards in the hollowing of ceramic tiles, and the hollowing of ceramic tiles is not subject to force and is easily damaged by external forces.
If the floor is soft and collapsed for a long time, it will easily cause the floor to deform and break. When stepping on the soft floor, it will easily cause damage to the floor lock, causing the floor to become loose. There are two situations in dealing with the collapse of wooden floors: There are generally large-area collapse and small-area collapse of wooden floors. Large-area collapse requires the ground to be leveled and reinstalled. Small-area collapse can be done by adding gaskets to the soft area. .
Metal parts are not equipotentially bonded: When bathing, the human skin is moist and the impedance decreases. The small voltage conducted along the metal pipes can cause electric shock casualties. Making "local equipotential bonding" in the bathroom can keep the bathroom at the same potential. Prevent dangerous contact voltage .
