Generally speaking, there are two ways to change the layout of the room, including partitioning and demolition of the wall. Addition of partitions is helpful to separate the empty space to form more uses; the demolition of walls can open the small room to re-adjust the indoor interval. , to expand the living area. Under normal circumstances, adding partitions will not produce too much impact on the structure of the house, and the demolition of the wall will cause a change in the structure of the load-bearing structure of the house. There will be cracks and heavy security risks.
Non-bearing wall, bearing wall identification?
Judging by sound: knocking on the wall, there is a crisp big echo, light wall, and bearing walls should not have too much sound.
Judging by the thickness: The wall thickness of the non-load-bearing wall in the floor plan is obviously thinner than the load-bearing wall, generally about 10 cm thick. The load-bearing walls are thick, second only to the exterior wall. The thickness is basically the same as the load-bearing wall, and its thickness is generally about 24 cm.
In general, when the load-bearing wall is a brick wall, the structure is 24 cm thick, the wall thickness in the cold area is 37 cm, the thickness of the concrete wall structure is 20 cm or 16 cm, and the non-bearing walls are 12 cm, 10 cm, and 8 cm.
Judging by location: The outer walls are usually load-bearing walls; also shared walls with neighbors. The general non-bearing walls are in bathrooms, storage rooms, kitchens and aisles.
These walls cannot be dismantled. Generally speaking, the bearing walls must not be moved. Even the large holes in the above areas will not work. Otherwise, the consequences will be serious. There is also a wall below the window of the old house balcony, called the weight wall, is used to balance the gravity of the balcony, there is a certain weight bearing on the balcony, so it is best not to demolish, especially the old house. However, even if the windows and brick walls are removed together, some property companies will allow it. This is mainly based on the specific conditions of the buildings.
Compared to the load-bearing walls, the non-bearing walls must bear at least two loads. One is the weight of the wall. Take a six-story residential building as an example, the non-supporting walls of the bottom occupants shall bear the weight of the above five walls, and each meter is long. The wall should bear a weight of 7300 kg. Second, structurally speaking, non-load-bearing walls are often designed as anti-seismic walls. In other words, in the event of an earthquake, these non-load-bearing walls will be subjected to seismic forces together with seismic walls. According to reports, this type of non-load-bearing wall cannot be demolished. Although it is not a big problem for a single family to dismantle non-load-bearing walls or make an opening on the wall, if residents of the whole building are willing to demolish the wall, they will Greatly reduce the building's resistance to earthquakes.
There is another kind of wall, that is, after the building is built up, the wall that rises behind a relatively large span is structurally speaking, it is a non-load-bearing wall, but it plays a great role in supporting the house and it is not free to Demolition reform.
In addition, the non-load-bearing walls underneath the concrete beams must not be tampered with. Because the beam is made of concrete, but for the weight of the floor and the wall above the beam, the beam does not directly bear the vertical load, but transmits it to the wall below, so the beam itself does not add much steel. Therefore, once the wall below the beam is dismantled, the beam will lose its supporting force and gradually deform or even fall.
Which walls can be removed?
For example, light structural walls, such as light steel keels, gypsum board walls, or cement board light walls, which are used as partitions for wall demolition, are not dangerous. Such non-load-bearing walls can be dismantled.
However, please note that for a half-brick wall of a bathroom, if a supporting beam with a supporting wall is designed in the floor structure, it can be removed, otherwise it cannot be removed. However, even if it can be dismantled, it must be prevented from damaging the waterproof layer, otherwise it will have to be redone.
Demolition of the wall notice of property management approval: the demolition of the wall is not an ambiguity, it is absolutely impossible to judge by the naked eye alone. No matter whether it is any wall, you have to obtain the consent of the property before you want to transform it. Otherwise, it is very likely that the property deposit will be deducted because it violates the requirements of the property.
Generally speaking, when the building is completed, the original design unit will leave a drawing for the property company. The wall thickness, material, etc. of the load-bearing wall, non-bearing wall, etc. are marked clearly. According to the drawings, the property company can determine which walls can be removed and which walls cannot be removed. If there are special circumstances, the occupants and the construction team should consult with the property company, and ask the relevant structural design personnel to take timely remedial measures and strengthen the measures that may occur after the demolition.
Pay attention to the circuit: In general, there are circuit lines in the wall. Care must be taken to avoid brute construction and break the circuit. At the same time, before the demolition, it is also necessary to consider the direction of the transformation of the circuit in detail. After all, the transformation of the circuit can be used to construct a part of the cost that is very watery. If you don't want the decoration company to make you too much money, it must be planned.
New house renovation adjusts the layout of the room
Although the selection of the house was selected and looked at and looked at when choosing a house, the type of housing that really made 100% of the buyers satisfied was only rare. Most homebuyers will make certain adjustments to the layout of their rooms according to their needs when they get new homes and begin renovations.
