Decoration design, you want to create a home that you are satisfied with, will inevitably transform the room type, demolition of the wall recast, the key is that this design is not as you like on the demolition of the wall is not free to split, if you do not pay attention, one is not careful, It may cause damage to the house. Seriously, it will collapse. In the news, there have also been accidents caused by the collapse of the house due to illegal wall-breaking. Therefore, in the design of housing, we must avoid these minefields that may lead to accidents. Then, where can the housing design fail? What is the difference between second-hand house demolition and new house? what should I be careful of? Below, we look at Xiao Bian!
Ten untouchable renovation minefields
1, bearing wall
In the renovation, the load-bearing wall cannot be changed and many people know it. But what kind of wall is a load-bearing wall, not many people can make it clear. Generally, in a brick-concrete structure, all prefabricated walls cannot be dismantled or doors can be opened; brick walls larger than 24 cm are also load-bearing walls and cannot be removed or modified. The walls that are knocked on by the “quiet voice†are mostly non-bearing walls and can be demolished. In addition, some people open the window on the load-bearing wall, which also undermines the weight of the wall. It is also not allowed.
If you want to demolish the wall in the house during the renovation, it is best for construction professionals to look at it to determine if it is a load-bearing wall before construction. Prior to construction, the property management department should also report to the record and be approved for construction. From a safety point of view, the load-bearing wall cannot be dismantled, and if you remove the load-bearing wall, your neighbor has the right to sue you and ask you to recover, so for safety reasons, do not remove the load-bearing wall. Of course, there are also professional construction companies that can remove some of the bearing walls and then use reinforcement methods such as embedment and sticking to achieve the original loading capacity. However, before the construction, they should be approved by the property.
TIPS: How to tell which wall is the bearing wall?
The best way to distinguish the bearing walls is to look at the drawings, but sometimes there is no relevant information in the hands, which is mainly determined by the thickness of the wall: Generally, the wall above 240mm is the bearing wall.
Some unrecognizable walls, such as walls and walls shared by neighbors, are also load-bearing walls. In a typical brick-concrete structure, there are load-bearing walls in addition to the walls of the bathroom and kitchen. The internal partitions in a framed house are generally not load-bearing walls.
2. Reinforcement in the wall
If the structure of the house is better than that of an adult, the steel bars in the wall are the bones of people. If the steel is damaged when the pipeline is laid, it will affect the bearing capacity of the wall and the floor. In the event of an earthquake, such walls and floors can easily collapse or break.
3, beams in the room
These pillars are used to support the upper floor slabs. After the upper floors are removed, they will fall, so they cannot move.
4. The low wall of the balcony
There is a window on the wall between the general room and the balcony. These doors and windows can be changed, but the walls below the windows cannot be moved. This wall is called "weight wall" and it acts like a scale to provoke a balcony. Demolition of this wall will reduce the bearing capacity of the balcony and cause the balcony to fall.
5. "Three Preventions" or "Five Preventions" Doors
The door frames of these doors are embedded in concrete. If the doors are demolished, they will damage the building structure and reduce the safety factor. It also destroyed the building structure at the entrance and it was even more difficult to reinstall the new door.
6, bathroom and kitchen waterproof layer
There is a waterproof layer under the ground in these places. If it is destroyed, the downstairs will become a water curtain hole. Therefore, be careful not to damage the waterproof layer when you replace the floor material. If you rebuild after destruction, you must do a “24-hour water seepage test†that is, watering in the kitchen or bathroom. If you do not leak after 24 hours, you must be qualified.
7, bathroom squatting pan
Some old houses also use old-style squat toilets. If you want to change to a toilet, be careful. Because the squatting pan is generally under water, and the toilet is generally under water, replacing the toilet means changing the sewer. This kind of construction is difficult, and the original waterproof layer must be destroyed. If it is not properly installed, it is not a water seepage downstairs.
8, heating and gas pipelines
The installation and demolition of gas pipelines must be done by a professional construction company of the gas company. The decoration company cannot “do it†and it must not cover the water meters, electricity meters and gas meters during the renovation. For heating and heating pipes, you must also be cautious because the location of the heating in the room directly affects the temperature in the winter room. If the demolition is not properly modified, it is not affected by heating. It is heating and running water.
TIPS: Changes to the Heating Pipeline and Water PipelineHeating pipes and upper and lower water pipes all have a common feature, that is, these pipes form an overall system within a certain range, and each household cannot be completely independent. Therefore, when such a pipeline is reconstructed, care should be taken to ensure that all modifications are done without affecting the entire system.
9, the original steel window
Some households changed aluminum alloy windows because the original steel windows did not look good. Due to the fact that a small number of decoration companies currently use small-size profiles in order to reduce costs, or simply shoddy, some aluminum alloy windows are much less robust than steel windows. The use of such aluminum alloy windows can easily cause shedding, especially in high-rise buildings.
10, do not slot horizontally
According to investigations, some construction teams have often made appearances of horizontal grooved wiring on the wall in order to facilitate the decoration. On the surface, this reduces the length of the wiring tube and saves money, but it destroys the wall structure. Caused serious security risks. The load-bearing wall of the horizontal slot was opened, like the glass that was crossed by diamonds. It was easy to break when it came to a strong earthquake.
According to experts, in principle, the light wall is not more than 50 cm in width; the wall on the load-bearing wall is not allowed to be grooved horizontally; the inner insulation wall is not more than 100 cm wide.
When second-hand housing works as a hidden project, you must also pay attention to the following four items:
1. Water reform: In the past, the water pipes used were mostly galvanized pipes, which could not be concealed or hidden. It is recommended that all pipes should be replaced with new ones such as PPR and buried in a dark place, which can greatly improve the integrity of the indoor space.
2. Electrical reform: The circuits of second-hand houses often have many problems, such as the use of aluminum wires with low safety, or the fact that all wires are not embedded directly in the wall, or the power distribution is unreasonable, etc. One of the problems is to re-do the entire indoor circuit. Reasonable distribution, air conditioning, air conditioning, lighting, lighting, with 2.5 square or 4 square copper wire, buried in the dark must wear the pipe, and the threaded pipe to choose high-quality pvc pipe.
3, Radiator transformation: the old-fashioned radiator of second-hand housing, certainly many people hope to replace, and many times, also need to move the location of the radiator, but this project must hire professional personnel to operate, if the change is unreasonable, It is easy to cause poor circulation of the radiator system, or the risk of water leakage in the future. Generally, radiator distributors provide professional services. It is advisable to seek them directly, and if necessary, they can consult the property again.
4, waterproof: After so many transformations, it is impossible not to destroy the previous waterproof layer, so re-do waterproof is essential.
Finally, to remind everyone that in the grooved pipe, if you encounter steel must not be destroyed, this will greatly affect the safety of the building!
With regard to the relevant contents of the decoration design which minefields cannot touch, Xiaobian has introduced it here. Whether your home is being renovated or is going to be renovated, you can look at these contents. Although the renovation works are not done by the owners themselves, they can’t blindly understand anything. Everyone can look at the decoration knowledge.
