Precautions for blank room Matters needing attention in blank room inspection

The house inspection project of the blank house must be done very carefully. If there is no problem when the blank house is closed, it will be particularly troublesome to deal with the problems once exposed after renovation, so the new owners need to pay special attention.

First, pay attention to the details of the blank house

1, main building

Whether the ceiling is flat and free from hollowing, cracking, shedding, rebar exposure and rust spots; Whether the wall surface is smooth, clean and uniform in color, without hollowing, cracking and explosion; Whether the ground is flat, free from hollowing, cracking, rebar exposure and sanding; Whether the balcony is flat, without cracks, floor drain and backwater; Whether there is a table holder in the kitchen, and whether the gap between the outlet copper valve, flue and ground level is up to standard; Whether the ground elevation difference of toilet reaches the standard or not, water storage test; Wall column, Yin and Yang Angle with and without size, verticality, verticality.

Step 2: doors

Whether the door frame is stable, grouted, well formed and firmly installed, and sealed with rubber strip; Whether the appearance of the door leaf is smooth, the paint surface is intact without sagging, brush leakage and bumping, and the color is consistent; Whether the door lock is firm, easy to operate and evenly locked; Whether the door handle is firm and the operation is flexible; Whether the door shaft is flat and firm, and whether it rotates smoothly; Whether the cat's eye is intact and the field of vision is clear; Whether the doorbell button is in good condition and the power-on sound; Whether there is a visual intercom,

Whether it is clear or not, the power can be heard. 3.Windows operating system

Whether the window frame is stable, geometric and smooth, and whether the material conforms to the contract; Whether the sash is firmly installed, whether the switch is flexible, whether it is tightly closed, and whether the material conforms to the contract; Whether the glass is intact (using safety glass); Whether the handle is intact, firm and flexible; Whether the sealing strip is tight and the window frame is tight; Whether the windowsill is in good condition, with and without cracks and immersion; Whether the height of the guardrail in front of the window meets the specifications, and whether it is safe, stable and unobstructed.

4. Circuit

Check the sockets: plug in five-hole sockets with indicator lights respectively, and the lights are on, indicating that there is electricity. At this point, pull down the socket switch in the main switch box (it should be marked) and the indicator light will go out. Frequent tests prove that the switch and wiring are good and the socket is safe. If the switch is pulled down and the indicator light of the socket is still on or flashing, it means that there is something wrong with the quality of the switch or the wiring, and it should be repaired immediately, otherwise it will be life-threatening if you accidentally get an electric shock. The socket should also be tested for good insulation to the ground with a shaking table; Each branch switch in the switch box shall be clearly marked.

If not, correct it immediately. The switches in the switch box should be installed firmly, and each switch should be shaken vigorously from left to right for inspection. If it is found to be loose, it should be tightened or replaced. Otherwise, it will cause greater danger when there is poor contact and fire in future use; Check whether the cable TV socket and broadband socket are loose or unplugged; Check the number of weak current sockets; Check whether the visual intercom and emergency call buttons work normally; Check the doorbell of the entrance door: use two No.5 batteries to test whether the doorbell doesn't ring or keeps ringing. 5. Waterway

Waterways are mainly embodied in kitchens and bathrooms. Toilets generally have two floor drains, a toilet drain, a bathtub drain and a washbasin drain. See if the setting is fair, and then decide whether it can be changed according to your own decoration needs.

However, the detailed transformation plan depends on the opinions of experts. 6, heating, gas

According to the room, check whether the heating pipes and radiators are installed tightly and firmly, whether the pipe joints are leaking, and check the suppression test records. It is very important to test the water before the heating period, so you must participate in it yourself and know the location of the main control valve of the household. Note that it is absolutely not allowed to dismantle and change the heating pipes and radiators without authorization.

Central air conditioning: the air outlet pipe, condensed water outlet pipe, temperature control switch and air outlet are correctly positioned and firmly installed. Special note: the position and function of kitchen exhaust duct and bathroom exhaust duct.

When the gas pipeline enters the household, whether the gas rooms of the main pipeline and branch pipelines are set, and whether the gas meters and control valves are complete. Note that it is absolutely not allowed to dismantle and modify natural gas pipelines without authorization.

7. Waterproof material

Waterproofing here refers to the waterproofing of kitchens and bathrooms. Of course, some of the houses currently delivered have already declared in advance that they are not waterproof.

This needs decorating. If it has been waterproof at the time of delivery, then we can't help but agree that the wrong waterproof is good or not. If you don't try it before decoration, then if you find water leakage after decoration, the maintenance project will be big. You have to tear down the newly decorated floor to make a new waterproof layer. 8. Pipeline

The pipes mentioned here refer to drainage pipes/sewage pipes. Especially seven is the balcony and other sewage outlets. At the time of acceptance, take a container of water in advance, and then pour the water into the sewage outlet. See if the water flows smoothly. Why do you accept this? Because in the process of construction, some workers often "steal" this job when cleaning. Pour some cement residue into the drain pipe and drain it away. If the cement is sticky, it will block at the elbow, causing drainage problems.

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 sewer pipe. According to experience, if there is no water storage and odor-resistant elbow in the sewage pipe, the overall quality of the house will be scored 12. Why do sewage pipes need this kind of elbow? Because the elbow will store water, the odor from the lower pipeline will be blocked under this layer. Without elbows, the sewers in laundry rooms and toilets will smell strange. Perhaps some developers will think that floor drain deodorization is enough. Engineering practice has proved that deodorizing floor drain is far from meeting the actual needs. Second, the blank room inspection matters needing attention

1, remember to "three books and one table"

When the blank house is closed, it is necessary to ask the developer for the construction project quality certificate, residential quality guarantee, residential instruction manual and completion acceptance record form. Among them, we should pay special attention to asking for the record form of completion acceptance. We should not only look at whether the developer has this record form, but also carefully check whether each item is filed, such as fire protection facilities. The Completion Acceptance Record Form is strictly binding on the business. As long as the project is reported to the competent authorities for the record, the developer must be responsible for life. If something goes wrong, if it is the fault of the developer, he can be held accountable.

2. Sign the property management convention before signing the acceptance certificate.

After you check the property and prepare to sign the house acceptance certificate, you must sign the property management convention first, and make an agreement in advance to avoid disputes in the future. You need to know what constitutes the property management fee to be paid in the future, and how to verify the cleaning fee, security fee and greening fee, so as to be clear. At the same time, check the qualifications of the property management company in your residential area to see if it meets the management standards you require.

3, blank room inspection depends on the six sides of each room of the house.

The wall of your house is painted with gray-black cement mortar. Do you accept white putty or paint and tile? Take a look at whether the wall color is uniform, whether the internal angle, external angle and gray line are straight and square, and whether the edges are neat. Touch the surface to see if it is not smooth, peeling, pitted, sanding, and knocking on the wall to see if it is empty. It is necessary to bother, but these are just general quality problems, and developers can rework and repair it.

4. Check the cracks in the blank room.

See if there are visible cracks in the walls and ceiling. Look at the location, length and regularity of cracks. If the cracks are irregular, short in length and large in number, accompanied by empty drum painting, it is only a general painting quality problem; If the cracks are oblique, horizontal, vertical and long, and they are connected together, and appear on the corners of doors and windows, vertical walls and external walls, and your home is on the top floor, it will be more troublesome. Many of these cracks are called temperature cracks. The width of temperature cracks is different in different seasons and at different temperatures, and changes cyclically. The reason is that the structural design of the building and the construction measures to prevent "common quality problems" are ineffective, and it is difficult to really solve the general rework and repair.

5, blank room inspection key waterproof.

The house is used to shelter from the wind and rain, but water leakage is the most prone to problems besides cracks. Whether waterproof is good or not can only be seen at this stage. First of all, look at smallpox: rooms, balconies, kitchens and bathrooms, to see if there are any water traces soaked in water, especially around the white drainage pipes hanging on the ceilings of kitchens and bathrooms. Then look at the wall to see if there are any water marks soaked by water in the corner of the outer wall, the hole of the air conditioning pipeline, the hole of the outer door and window, and the window sill. Finally, look at the outer door, the closing place of the door and window sash, the door and window frame, and the splicing place of the sash to see if there are any water traces that have been leaked by water.

6. It is very important to check the doors and windows of rough houses.

Good quality doors and windows, the surface should be clean, flat, smooth, bedding face without scratches, bumps; The materials of window frames, crosspieces and sashes are not warped or deformed; The sealing strip around the door window frame is complete and firm, and there is no leakage; After the doors and windows are naturally closed, the frame and the fan naturally stick together, and the size around the gap is the same. There is no crack, damage or looseness in the door and window glass, and there is no dust and water vapor in the hollow inner layer of the hollow glass; The joint between rubber sealing strip and glass and glass notch is smooth, without edge, groove and fracture; Sealant should be firmly bonded, with a smooth and straight surface and no cracks.

The above is the relevant introduction of this article. I believe you will have a simple understanding of this after reading it. If necessary, you can continue to pay attention to the 1 home network for more information.

At the same time, be sure to carefully check whether each sub-item has been filed, such as fire control facilities. The Completion Acceptance Record Form is strictly binding on the business. As long as the project is reported to the competent authorities for the record, the developer must be responsible for life. If something goes wrong, if it is the fault of the developer, he can be held accountable. 2. Sign the property management convention before signing the acceptance certificate.
