Property maintenance standard is property maintenance.

The level of property maintenance management, that is, the standard of property maintenance, varies with the location of the property, the property management enterprise and the specific situation of the property, but it still has many characteristics.

I. Main projects

There are two standards for major project repairs:

1. Roof truss, column, beam, purlin, floor, etc. Hidden dangers should be found when repairing, and those damaged or deformed seriously should be reinforced, reinforced or replaced. Unreasonable old structures and joints should be modified during overhaul if they affect safe use. When repairing, masonry or reinforced concrete members should be used as far as possible to replace the severely damaged wood structure. For reinforced concrete members, if they are slightly peeled off or damaged, they should be repaired in time. When the concrete is carbonized, cracked, peeled off and the steel bar is seriously corroded, it should be tested and calculated to identify the bearing capacity of the component and take reinforcement or replacement measures.

2. Uneven settlement of foundation affects the superstructure, arching, inclination, cracking and deformation of masonry, and the reasons should be found out and reinforced or removed in a targeted manner.

Second, the wooden doors and windows and decoration engineering

Wooden doors and windows repair should be flexible switch, tight joints, not loose; Wood decoration engineering should be firm, smooth and beautiful, and the joints should be tight. There are seven specific maintenance standards for wooden doors and windows and decoration works:

1. If the switches of wooden doors and windows are inflexible, loose, broken tenon and damaged, they should be repaired and replaced, and the hardware should be repaired and replaced. During maintenance, the inner and outer glass should be assembled at one time, and the putty should be embedded firmly. Wooden doors and windows are badly damaged and cannot be repaired, so they should be replaced; The doors and windows replaced in the first-class room should be consistent with the original doors and windows as far as possible. If the material is idle, it can be replaced with steel doors and windows or other doors and windows with better cutting materials.

2. Screen doors, screens, shutter doors and screens are generally damaged and need to be repaired. Serious damage, a house and kindergartens, nurseries, hospitals and other special users can be replaced; The second-class room can be demolished. What didn't exist before will not be newly installed.

If the wooden stairs are damaged, they should be repaired. If the lower part of the stair base is rotten, it can be replaced with brick steps. Handrails, stair foundations and platform grilles shall be firm and safe. Serious damage, conditions permit, can be changed to brick walls.

4. Lightweight partition walls such as board walls and thin walls are damaged and should be repaired; Serious damage, conditions permit, can be changed to brick walls.

5. Wooden balconies and balconies are generally damaged and need to be repaired; Serious damage can be removed, but try to solve the heat dissipation problem.

6. Decorations such as hanging mirror lines, curtain boxes, window sills, bobbin boards, closets, fireplaces, etc. Generally damaged, it should be repaired as it is. Seriously damaged, the first-class house should be updated as it is, or replaced with other materials without affecting the use of the standard; The second-class room can be changed or demolished.

7. The skirting board should be repaired if it is partially damaged, incomplete and falls off; Most of the damaged parts can be replaced with cement skirting boards.

Third, the floor engineering

There are four maintenance standards for building and ground engineering:

1. If the damage of ordinary wooden floor accounts for less than 25% of the natural area, it can be repaired; Damage more than 25% or lack of wood, can be changed to cement floor or block floor; When the wood floors and high-grade hardwood floors in first-class houses, kindergartens, nurseries, hospitals and other special rooms are damaged, they should be repaired as much as possible. If it can't be repaired, it can be replaced with a high-grade floor of the corresponding standard.

2. Wooden stairs are damaged, loose and incomplete and should be repaired; If the wear is too thin and affects safety, it can be partially removed and replaced; If conditions permit, it can be changed into a reinforced concrete floor. When the top hardwood floor of the first-class residence or the top floor of other materials is damaged, it should be repaired as much as possible; If it can't be repaired, you can change to a higher floor of the corresponding standard. If the floor with sand (wood base, concrete or concrete surface) is damaged, the reinforced wood base can be clamped to repair the surface. It can also be converted into a reinforced concrete floor. If the wooden stairs are rotten, twisted, damaged and lack of rigidity, they should be replaced, filled or other reinforcement measures should be taken.

3. If the ground of ordinary cement building is sanded, hollowed and cracked, it should be repaired or redone. When the terrazzo or block floor of the first-class residence is damaged, it should be repaired as much as possible; If it can't be repaired, you can change the floor to the corresponding standard.

4. Brick floor is damaged, broken and uneven, which should be repaired or resurfaced. If the indoor humidity is serious, you can add moisture-proof layer or cement and block floor.

Fourth, roofing engineering

Roof engineering repair standards, there are the following six:

1. If the roof structure is damaged, it shall be repaired or replaced; It is unstable and should be reinforced. If the original structure is too simple, or the running water is too long, the slope is small, and the cold tiles cause serious water seepage and rain leakage, and the original repair can not rule out the leakage of the house, it is necessary to renovate and rebuild.

2. Roof coping, lead-out, roof ridge, backwater, skylight, gutter, eaves gutter, inclined gutter, downpipe, water pipe and other damaged seepage shall be repaired; The damage is serious and should be turned in. During overhaul, the original downpipe and water pipe should be repaired and equipped. Houses above the second floor do not have downpipes and water pipes, and they can be added if conditions permit.

3. Roof accessories such as parapets and chimneys are seriously damaged and can be repaired or removed without affecting the city appearance and use conditions.

4. For the leakage of reinforced concrete flat roof, find out the reason, and use waterproof material to repair or make waterproof layer according to the damage; The structure is damaged and should be reinforced or redone.

5. If the glass ceiling and tiger window are damaged and leaking, they should be repaired; If the damage is serious, it can be turned over, but it is generally not new.

6. If the original insulation layer of the roof is damaged, it should be repaired.

Five, plastering engineering

There are four repair standards for plastering works:

1. External wall plastering and peeling should be repaired; If the damaged area is too large, it can be completely removed and repainted. If the original plastering material is too poor, the material standard can be improved. First-class houses and houses in main streets and squares along the street are damaged by plastering, and should be repaired as they are; If it is difficult to recover, it can be replaced by other materials without lowering the material standard and affecting the color coordination.

2. If the drywall is damaged, caulking should be repaired; If the whole wall is too weathered, it can be plastered. If the external wall is damaged, it should be repaired; If you don't wipe your feet, you can do it again.

3. The interior wall plastering shell, peeling, should be repaired; If more than half of each wall is damaged, it can be torn down and repainted. If there is no skirting line, cement skirting line should be added in combination with interior wall plastering. All kinds of dado damage should be repaired or plastered with cement dado according to the needs of protecting the wall. If the wall is wet for a long time due to the height difference between indoor and outdoor or the influence of ditches, it can be used as a waterproof layer.

4. When the ceiling plaster is damaged, pay attention to check the internal structure to ensure safety. If the plastering layer is loose and in danger of falling off, it must be removed and redone. If the original cable leg is damaged, it should be repaired as it is. After all seriously damaged and complicated column foundations are removed, if they are first-class houses, they should be repaired as they are, or simplified appropriately; Houses below the second category can be repaired.

Six, paint painting project

There are five repair standards for painting and plastering works:

1. Wooden doors and windows, gauze doors and windows, shutter doors and windows, sealing plates, skirts, wooden railings and other paints are shelled, peeled and lose their protective effect, and should be maintained regularly; All or part of the above wooden components shall be removed and painted.

2. Steel doors and windows, iron hangers, iron downpipes, iron roofs, steel roof trusses and supports, cast iron sewage pipes or other various iron components (iron bars, iron railings, iron gates, etc.). ) should be derusting, brush derusting paint or paint. The maintenance period of steel doors and windows or various iron paints is generally 3-5 years.

3. The crude oil on the wooden floor falls off, and the first-class room should be redone; Second-class rooms can be handled according to specific conditions.

4. Indoor walls and ceilings can be refreshed after being repaired. Its materials, first-class houses can use new paint, glue white and so on. Houses below second class can be painted with lime water. Advanced plastering is damaged, so it should be repaired as it is.

5. If the original paint of high-rise buildings or houses along the main streets and squares is damaged, it should be repaired and kept consistent with the original color as far as possible.

Seven, water, electricity, sanitation, heating equipment engineering

The repair standards for water, electricity, sanitation and heating equipment include the following four items:

1, the maintenance of electrical lines shall comply with the operating procedures of the power supply department. If there is no household electricity meter, installation service can generally be provided, unless otherwise stipulated by the local authorities, but the electricity meter and accessories should be provided by the user; Each room is subject to one socket and one lamp, and it will not be modified at ordinary times.

2. The damaged, blocked and incomplete parts of sewage and sanitary equipment shall be repaired or dredged, but the expenses caused by man-made damage shall be borne by the residents themselves. If there is no sanitary equipment, whether it is newly installed shall be implemented according to local regulations.

3. The damage of pressure water tanks, sewage pipes, pump houses, water towers and water tanks attached to multi-storey and high-rise residential buildings and their groups shall be repaired unless otherwise agreed with the water supply department; If the original design is defective or unreasonable, the design should be changed and reinstalled. The water tank should be cleaned regularly.

4 elevators, heating, pipes, boilers, ventilation and other equipment damaged, should be repaired in time; If the spare parts are incomplete, they should be complete; If it is not used for a long time, it still has no use value in the future and can be removed.
