1. Look at the wall. I don't know when it started, but looking at the wall turned out to be the primary problem of house acceptance. In fact, even the houses built in the 198s are not as fragile as the present ones. I have seen the most serious house, and the windows were found to have water seepage in rainy days. When I asked, I realized that the walls under all the windows in the whole building had water seepage. When the typhoon comes, it is even more frightening, and what is even more surprising is that this building was built by a district land and resources bureau, which is terrible. Therefore, it is best to inspect this before the house is handed over and the day after the heavy rain. At this time, if there is a problem with the wall, it is almost inevitable. In addition to water seepage, there is another problem, that is, whether the wall is cracked. A friend once reported that there was a door-shaped crack in his home. Later, when he asked the developer, he realized that it was the elevator cargo port left during construction. Later, when it was closed, it was handled carelessly, leaving future troubles. 2. Check the water and electricity. The first thing is to check whether the water and electricity of the house are connected. Of course, for some advanced decoration, most of the water and electricity will be replaced later, so sometimes these contents are not critical, but if you don't plan to replace the water and electricity, then these things must be carefully checked and accepted. Wire inspection, in addition to seeing whether the electricity is connected, mainly depends on whether the wire meets the national standard quality. Then there is whether the cross-sectional area of the wire meets the requirements. Generally speaking, the wires at home should not be less than 2.5 square meters, and the air-conditioning wires should reach 4 square meters. Otherwise, when using air conditioners, it is easy to overheat and soften. Of course, this is an ideal configuration, and most civil wires will be one grade worse. 3. Check waterproof. The waterproof mentioned here refers to the waterproof of kitchen and bathroom. Of course, some of the houses currently delivered have already stated in advance that they are not waterproof, which requires decoration. If it has been waterproof at the time of delivery, then we have to verify whether it is waterproof. If you don't try it before decorating, then if you find water leakage after decorating, then the maintenance project will be big. You have to tear down the newly decorated floor to make a new waterproof layer. The way to check and accept waterproofing is: use cement mortar as a sill to block the door of the toilet, then cover the sewage/water outlet with a plastic bag, then tie it up, and then drain water in the toilet, just shallow (about 2cm high). Then make an appointment for the owner downstairs to check the smallpox in his toilet after 24 hours. The main leakage positions are: direct leakage of the floor; The contact between the pipe and the floor. 4. Inspection pipeline The pipeline referred to here refers to the drainage/sewage pipeline. Youqi is a sewage outlet such as a balcony. When accepting, take a water container in advance and then pour water into the sewage outlet. See if the water flows away smoothly. Why do you want to accept this? Because during the construction, some workers often "steal" this job when cleaning. Pour some cement residue into the drainage pipe and flow away. If the cement is sticky, it will block at the elbow, which will make drainage difficult. There is another situation, but it has nothing to do with acceptance. That is to see if there is a water storage and odor-resistant elbow in the sewage pipe. According to experience, if the sewage pipe does not have a water storage and odor-resistant elbow, then the overall housing quality will have to be scored 12 points. Why do sewage pipes need this kind of elbow, because the elbow will store water, so the odor from the lower pipeline will be blocked under this layer. Without elbows, the drains of laundry rooms and toilets will emit an odor. Perhaps some developers will think that deodorizing floor drain is enough. The practice of the project proves that deodorizing floor drain is far from meeting the actual needs. It is precisely because of this small place that the construction quality of builders can be best reflected. 5. Checking the ground level is actually difficult for general users to accept this. Checking the horizon is to measure the horizontal error between the indoor ground farthest from the door and the ground inside the door. Inspection of this, in many cases, can also reflect the construction quality of developers. Because as the owner, it is impossible to accept the main structure. Then the quality can only be seen from these details. The method of measurement is quite simple if you don't bother. Go to the hardware store and buy a small transparent water pipe, about 2 meters long, and then fill it with water. First, draw a sign at the door .5 meters or 1 meter from the ground. Then adjust the water level of the water pipe to this mark height and find someone to fix it in this position. Then move the other end of the water pipe to the room farthest from the door. Then look at the height of the water pipe there, and then make a sign. Then measure the height of this sign from the ground with a ruler. These two height differences are the level difference of the house. You can also measure the horizontal difference of the whole house by analogy in this way. Generally speaking, if the difference is about 2 cm, it is normal, and 3 cm is acceptable. If you go out of this range, you have to pay attention. I have seen the worst horizontal difference of 7 cm, and after measurement, I thought I had made a mistake. The above work is a bit cumbersome. If you have a friend who owns a laser scanner, this problem will be much easier to solve. 6. Inspection height If there is such a clause in your contract. Then you should measure the height of the building. The method is very simple. Measure the ruler along the internal angles of two of the walls (this is the best way to place the long ruler conveniently without bending). You should measure many places in the room. Generally speaking, about 2.65 meters is an acceptable range. If the house is less than 2.6 meters, then the house will have to be considered. This kind of house will make you have to live in a depressing environment in the future. For developers, it is a very effective way to save costs. 1) reduce the total load, so that the cost of the foundation part can be saved. 2) Although it is only reduced by about 1 cm, overall, there are many cost savings, especially for residential areas developed in pieces. 3) In a certain height, more floors can be built by lowering the height. 7. Inspection of doors and windows Here, the inspection window is the main one. The key point of acceptance is the tightness of the acceptance window and balcony door. The most troublesome thing about window sealing acceptance is that it can only be tested on rainy days. But it can generally be confirmed by checking whether the sealing strip is complete and firm. The balcony door generally depends on the horizontal difference between the inside and outside of the balcony door. I have seen a situation where the level of balcony is actually the same as that of indoor, so it is difficult to avoid the problem of rainwater infiltration in rainy days. 8. Other projects In fact, in addition to the above-mentioned projects, other inspections require more professional knowledge. You might as well take a friend who is familiar with the project to check and accept the house, which is the only possible thing. Besides, you can only rely on the seriousness of the quality inspection part.
