Is it necessary to file a record with the property for house demolition and reconstruction?

House demolition and renovation must be filed in the property, and the property will have a house structure diagram, which can determine which walls are load-bearing walls that cannot be demolished. Before the demolition and reconstruction, the owner will submit the design drawings of the house demolition and reconstruction to the property for record, and the construction can be started after confirming that the location of the demolition and reconstruction can be moved.

Problems needing attention in house demolition and reconstruction

1, the wall can't be opened casually.

Generally speaking, the walls of brick-concrete buildings are load-bearing walls, because load-bearing walls are walls that support the upper floor of buildings and transfer components to the next floor. The load-bearing wall is not only related to the stability of one's house, but also to the safety of the whole building. External walls and household walls cannot be dismantled, reinforced concrete columns cannot be dismantled, and the whole concrete wall of frame-shear wall structure cannot be dismantled.

How to tell? Look at the symbols on the construction drawing paper. Brick walls with a thickness of 240mm and 180mm cannot be demolished. If you can't tell the difference, you can let the decoration company or your own property consult.

Lightweight wall, gypsum board wall, which can be disassembled and refitted in home decoration, is a common hard partition wall and usually does not have load-bearing function. Semi-brick walls generally appear in bathrooms, kitchens and other places. When the supporting wall and supporting beam are installed in the floor structure, they can be safely removed. But there are two things to remind:

(1) Before dismantling the semi-brick wall, it is best to look for the construction drawing of the constructor to make sure that it will not cause potential safety hazards after dismantling.

(2) Pay attention to waterproof again after tearing down the wall, because tearing down the wall will usually cause damage to waterproof. Wooden partitions are generally used to divide the space, and everyone can tear them down. Except for wooden partitions, most metal partitions and CRC partitions can be safely removed, but before removal, it is necessary to pay attention to whether there is water and electricity wiring in these partitions, because some older second-hand houses still have many problems of disorderly wiring, so it is beneficial and harmless to pay more attention when removing walls.

2. Don't change the balcony function.

When it comes to balcony modification, the owner had better think twice. Take the balcony converted into a kitchen as an example. The balcony has pipes, household appliances or gas. Once the strong wind blows out the fire in the heavy rain, it will easily lead to gas leakage. If pipes and appliances are struck by lightning during a thunderstorm, the consequences will be unimaginable. So it's best to think more before the balcony renovation.

Some people tear down the lower wall of balcony windows in order to increase indoor space, broaden their horizons or increase lighting, which is absolutely unsafe. Balcony, ring beam and window lower wall are a whole, and the glass window is above the window lower wall. Although it does not play the role of bearing, the side of the balcony slab is pressed under the wall, which plays the role of bearing down, so the wall under the balcony window must not be removed.

In order to increase the utilization rate of the balcony, some people extend the front edge of the balcony outward, build slabs, install boxes on the slabs to store sundries, or install air-conditioning hosts on the slabs. This not only affects the appearance of the building, but also causes unsafe hidden dangers, especially the vibration caused by the day and night operation of the air conditioner, which will cause continuous damage to the balcony.

In order to increase the usable area, closed windows and walls are installed on the cantilever balcony, which is larger than the balcony plane cantilever, and the cantilever space is full of sundries and flowerpots. These practices will cause the root of the cantilever beam supporting the balcony load to break due to overload, which will seriously lead to the balcony falling.

3. The height of the socket should not be low.

Some business owners will put the socket position in a relatively low position when planning the socket position, thinking that even if the wire is short, there is no need to worry about reaching the socket. The position of the socket is too low, which is easy to be splashed by water, resulting in leakage. Daily walking will also kick the socket. It is even more dangerous if the child sticks his finger into the socket out of curiosity.

Home decoration looks interesting, but the professionalism involved is not something that ordinary people can master. If you want to change the household pattern, it is best to consult professionals and get professional advice before starting construction, otherwise it will not be worth the candle.

4, the ground decoration should not be too thick.

The focus of ground decoration, whether it is paving floor tiles or granite, including the thickness of cement ash can not exceed 2 cm. In this way, the floor weighs about 25 to 30 kilograms per square meter, so don't make the floor too thick when decorating. According to the safety regulations, the weight of building floor decoration materials shall not exceed 40kg/m2.

5. Don't change the water, electricity and gas pipelines at will.

Safety and standardization should be paid attention to in gas and water pipeline reconstruction and electrical reconstruction, especially in case of disaster, it can be closed as soon as possible, which is convenient and fast. At the same time, pay attention to the standards and safety of materials used.

Residents or decoration personnel dismantle and change gas pipelines and package gas valves without permission, which is easy to cause gas leakage. When the gas pipeline is encapsulated, gas leakage is not easy to be detected, and the leaked gas is not easy to spread and gather locally. Without professional safety inspection before use, an open flame will inevitably cause an explosion.

Gas facilities have strict technical specifications and safety requirements in design and installation, and must be constructed by professionals. If it is really necessary for residents to change the gas pipeline when decorating their rooms, they should apply to the gas supply unit, which will conduct on-site investigation and make comments. Can be changed, the gas supply unit out of the construction plan, operated by professionals, to have professional qualifications.
