What is the correct acceptance standard for repossession?

The contents of the correct acceptance criteria for recovery are as follows:

First, the entrance inspection.

1. Inspection standard

(1) The surface of the door shall be clean and free from scratches and bumps;

(2) The cutting angle and flat-fell seam of the door should be tight and smooth;

(3) The gap between the door and the wall should be full;

(4) Allowable deviation of door fabrication: allowable deviation of door frame warping is 3mm, allowable deviation of door leaf warping is 2mm, allowable deviation of door leaf surface flatness is 2mm, and allowable deviation of diagonal length between door frame and door leaf is 3 mm;

(5) Limit value and allowable deviation of installation joint: the width of door leaf butt joint and vertical joint between door leaf and door frame is1.5 ~ 2.5 mm;

(6) The gap width between the entrance door of the blank house and the ground should not be less than 3.5cm.

2. How does the owner check whether the entrance door meets the house quality acceptance standard?

In general, the owner should check the following aspects of the entrance door:

(1) Door frame inspection: whether the door frame is installed firmly and smoothly, whether the joint between the door frame and the wall is tightly sealed, and whether there are abnormal burrs, cracks and damages on the surface of the door frame;

(2) Door leaf inspection: whether the door leaf is deformed or cracked, whether the appearance of the top paint is intact, whether the surface is smooth, whether there are obvious scratches and bumps, and whether the ground decoration method is reserved from the ground;

(3) Door lock inspection: whether the door lock is firmly installed, whether the key is inserted and removed smoothly, whether the lock core rotates freely, whether the lock tongue is fully retractable, and whether the keyhole position is normal;

(4) Open the door for inspection: whether the door is open and closed smoothly, whether there is abnormal resistance and wear, and whether there is shaking behind the door lock;

(5) Door handle inspection: whether the door handle is firmly installed, whether there is abnormal resistance during rotation, and whether there is defect or deformation on the surface;

(6) seal inspection: whether the door leaf joint is within 2.5mm. ..

General owners pay more attention to the appearance quality of doors, such as slight scratches and bumps on the door surface, serious panel cracks and deep scratches. , may have caused damage to the door during the construction process. Minor damage can be repaired by on-site repair and paint touch-up, and serious damage can be repaired in the factory. When the width of the gap between the entrance door and the ground does not meet the requirements (less than 3.5cm), you can ask for anti-factory sawing (note: the determination of sawing after returning to the factory for maintenance is generally persuaded by the property site as far as possible, and the owner is generally not allowed to decide casually, so you can ask the real estate engineering department to make a judgment and decision); Problems with door locks usually occur in the process of decoration and use. If it is found that the key is universal and the lock can't be opened, it can be replaced if there is a quality problem on site.

Second, aluminum alloy doors and windows inspection

1. Inspection standard

(1) quality of aluminum alloy doors and windows: the surface should be clean, flat and smooth, with the same color and no rust; The bedding face should be free of scratches and bumps;

(2) Allowable deviation of aluminum alloy doors and windows installation: the vertical deviation of the front and side of the door and window frame is 2.5mm, the horizontal deviation of the door and window cross frame is 2mm, the elevation deviation of the door and window cross frame is 5mm, and the vertical deviation of the door and window from the center is 5 mm.

(3) The gap between aluminum alloy door window frame and wall should be filled and sealed with sealant. The surface of sealant should be smooth, straight and crack-free;

(4) The rubber sealing strip of aluminum alloy door and window sash shall be installed in good condition, and shall not take off the groove, and the set drainage holes shall be unobstructed;

(5) The switch stress of aluminum alloy door sash is not greater than100n;

(6) Installation quality of aluminum alloy door and window glass: the glass surface should be clean, free of putty, sealant, paint and other stains. The inner and outer surfaces of insulating glass should be clean, and there should be no dust and water vapor in the glass hollow layer.

2. The owner shall check the following aspects of aluminum alloy:

(1) window frame inspection: the window frame is installed firmly and correctly, and whether there are scratches, bumps, deformation, etc. On the window frame;

(2) Appearance inspection: The surface layer should be uniform in color, smooth to the touch, and free from scratches, bumps and deformation.

(3) Hardware and opening inspection: the switch should be free and stable, push and pull freely, the track parts should be installed firmly, and there should be no air leakage after closing the window;

(4) Sealing inspection: whether the sealing strips between sash and window frame, sash and glass are in place and tight, whether there are problems such as breakage and discontinuity, whether the sealing strips between window frame and wall are complete, whether there are problems such as falling off, breakage and cracks, and whether there is leakage;

(5) Glass inspection: the installation is firm and complete, without cracks and obvious scratches.

The damage of aluminum alloy window frame profile needs to be determined on site. If there are small scratches and bumps (without affecting the use function), you can repair the painting on site. If there is serious deformation affecting the use function, it can be replaced. In addition, the owner is more concerned about the leakage of aluminum windows and found that the leaking windows need to be rectified.

Three, balcony railings, window guardrail inspection

Inspection standard:

1. Quality of finished guardrail: the guardrail surface shall be smooth, free from corrosion, uniform in color, free from cracks, warping and damage, and the joints shall be tight;

2. Allowable deviation of guardrail installation: the allowable deviation of guardrail verticality is 3mm, and the allowable deviation of guardrail spacing is 3 mm. The guardrail installation must be firm and correct;

3. The clear height of the balcony railing or railing of the residence shall not be less than1.05m; Six floors and below; Seven floors and above shall not be less than 1. 10m. The clear distance between railing uprights should not be greater than 0.11m.

General owners pay more attention to the surface quality and installation of guardrail, and most of the problems reflected are rust and improper installation of guardrail. Such problems can be corrected. In order to improve work efficiency, it is suggested that the construction unit can provide some paint for the property, and the property maintenance personnel can simply touch up the paint. If it is difficult to rectify, notify the real estate engineering department for arrangement.

Fourth, ground inspection.

1. Ground inspection standard

(1) The ground is firmly combined with the next floor, and there can be no hollowing (considering the actual level of China's construction enterprises, when the hollowing area is more than 400 square centimeters, there is no crack, and there are no more than two natural rooms or standard rooms, which can eliminate the construction quality defects of hollowing);

(2) The ground should be dense, free of sand, honeycomb, cracks and other quality defects;

(3) Ground allowable deviation: the allowable deviation of surface flatness is 5mm, the allowable deviation of elevation is 8mm, and the allowable deviation of thickness is not greater than110 of design thickness;

(4) It is forbidden to leak at the riser, casing and floor drain on the ground with waterproof requirements, and the slope direction is correct without water accumulation.

2. The owner should check the following aspects of the ground.

(1) Whether there are quality defects such as hollowing, cracking, peeling, pitted surface and sanding on the ground;

(2) Whether there is backflow and water accumulation on the ground;

(3) Whether the ground plumbing embedded pipeline is marked;

(4) Whether the ground is reserved for decoration.

V. Wall inspection

1. wall inspection standard

(1) The plastering surface of the wall shall be smooth, clean and smooth.

(2) The plastering layer on the wall must be firmly bonded with the grassroots, and the plastering layer shall be free from delamination and hollowing, the surface layer shall be free from ash explosion and cracks, and the external wall shall be free from water seepage;

(3) drip line (trough) should be made for the parts with drainage requirements, and drip line should be neat and straight, with high inside and low outside;

(4) Allowable deviation of wall plastering: the allowable deviation of verticality of facade is 4mm, the allowable deviation of surface flatness is 4 mm, and the angle of yin and yang should be square, and the allowable deviation is 4 mm. ..

General owners pay more attention to wall quality, such as plastering and hollowing, wall cracks and so on. In the actual inspection, the allowable range of wall hollowing is: the single wall is less than 5 square meters, and hollowing is allowed at 1, and the hollowing area is not more than 5 square centimeters; The single-sided wall is more than 5 square meters, and at most two empty drums are allowed, and the area of each empty drum is not more than 5 square centimeters; The causes of wall cracks are mainly influenced by temperature and materials. Due to the different expansion coefficients of materials and the influence of temperature, cracks will appear in walls made of different materials.

2. General crack inspection points

Wall cracks and floor cracks are the focus of attention when the owner repossesses the building and must be paid attention to. The main points of general crack inspection are as follows:

(1) Check whether there are cracks on the external wall of the house (there are hidden dangers of water leakage);

(2) Whether there are cracks in the load-bearing wall, whether the cracks run through the whole wall and through the back, and whether there are oblique cracks (with structural safety hazards);

(3) Whether there are penetrating cracks in the load-bearing wall and whether there are directional and regular cracks in the same position of the wall on different floors (there are structural safety hazards);

(4) Check the floor (floor and roof) for through cracks (cracks parallel to the beams). According to Article 8. 1. 1 of Code for Acceptance of Construction Quality of Concrete Structure Engineering, the crack width (0.3mm) is a general defect and does not affect the bearing capacity of cast-in-place slab.

(5) Check the floor (ground, roof) for stress cracks, which generally appear on the bearing surface or at the bottom of the middle plate. This kind of crack is generally manifested as a crack at an angle of 45 degrees with the corner, a crack perpendicular to the beam, etc. These cracks are often not straight, and the shape is wide outside and narrow inside. It should be said that this kind of crack often affects the safety and durability of the structure and needs to be paid attention to;

(6) Whether there are through cracks in cantilever structural plates such as balconies and awnings (there are structural safety hazards)

Six, waterproof inspection

Inspection standard:

(1) The surface of the waterproof layer shall be smooth, free from defects such as foaming and wrinkling, and the rigid waterproof layer shall be free from defects such as looseness, cracking and sanding. The drainage slope of waterproof layer meets the design requirements, and there is no obvious water accumulation.

(2) The detailed structure meets the specified requirements, with tight seal and no leakage.

The waterproof quality of houses is an important quality problem that owners pay attention to. Waterproof inspection mainly includes the waterproof inspection of bathroom, balcony, kitchen, roof, external wall, external wall doors and windows, and air conditioning hole. Among them, the owners of bathrooms, balconies, kitchens and roofs will require a 24-hour closed water experiment for inspection when repossessing the building. If there is any leakage during the inspection, it must be rectified and tested again until there is no leakage.

Seven, water supply and drainage inspection

In addition to the reserved pipes, there is almost no description of water supply and drainage facilities in the blank room, and no sanitary appliances are installed. The owner pays attention to the following contents:

(1) Inspection of existing valves and faucets: whether the position is reasonable, whether the opening and closing are normal, whether the waterway is unobstructed, and whether there are any phenomena such as damage, corrosion, sliding button failure and dripping;

(2) whether the pipeline is fixed firmly, whether the installation is straight and tidy, whether the pipeline is damaged and whether the joint is in good condition;

(3) Whether water plugs, pipes, etc. are reserved. Considering the size of the decoration surface, whether the water plug is opened;

(4) Water meter inspection: whether the water meter installation conforms to the specifications, whether the water meter joint is tight and intact, and whether there is idling phenomenon;

(5) Inspection of drainage pipes: Whether the drainage pipes have right angles and dead angles; Whether the joint is tight and intact, whether there is leakage at the interface, whether the pipeline is unblocked, whether the pipeline is fixed, installed neatly and undamaged; Whether the extension pipeline upstairs is too long or too low affects the decoration;

(6) Detection of drain and floor drain: whether there is a floor drain, whether the floor drain position is reasonable, whether the drain and floor drain are complete and whether the seal is tight;

(7) The drain should be blocked to prevent garbage from entering the drainage pipeline and causing pipeline blockage.

Eight, electrical inspection

For the electrical and equipment owners of blank houses, the following contents should be checked:

(1) Inspection of household distribution box: the installation verticality of distribution box meets the requirements of national specifications; The box and decorative board are clean inside and outside, without scratches and color difference; The door can be opened flexibly; All switches and leakage protectors in the box act correctly and the control range is correct; The wiring in the box is neat and the loop number is complete and correct; I want to be firmly connected to the switch;

(2) Electric meter inspection: the installation of the electric meter conforms to the specifications, and there is no idling phenomenon after the main gate is closed;

(3) Inspection of switch socket: the surface of switch and socket panel is clean and free from damage; The switch control range is correct; The switch cuts off the phase line, and the phase, zero and ground connections of single-phase two-hole and single-phase three hole socket are correct; Cover plates of concealed switches and sockets shall be installed firmly, close to the wall and seamless around; The wire connection meets the requirements of national specifications;

(4) Lighting inspection: lamps and lanterns are installed firmly and correctly;

(5) Other weak current systems: the acceptance of intercom access control, security and audio system should follow the corresponding national standards.

Pay attention to receiving the check-in notice in time.

1. This is the first step to repossess the house. Pay attention to the deadline Generally, the time limit agreed by developers is within 30 days after the notice is issued, and the buyers will arrange their own time.

2. After receiving the occupancy notice, we must first judge whether the developer delivers the house as scheduled. If the delivery is overdue, it is necessary to make suggestions, decide whether to look at the house according to the developer's reply, and look at the house according to the time agreed in the notice.
