How to tell if the wall in your home can be removed? What kind of walls can t be removed?

First of all, the load-bearing wall.

It is immovable, and the load-bearing wall is the majority of the frame structure that carries the main body of the upper floor.

If it is removed, the upstairs frame is equivalent to losing the support, many houses are on the top of the beam, which affects the aesthetics, some owners want to remove it, but it must not be demolished, because it supports the upper floor, we can only use the design of the ceiling to cover it. This weakens the sense of presence of the beam. A load-bearing wall is a wall that supports the weight of the upper floor slab and is shown in black on the engineering drawings.

If this wall were to be demolished, the entire building structure would be destroyed.

That is, the floor slab is the main wall and lamp component supported on the load-bearing beam, and the weight of the floor slab and furniture of our house is transmitted to the main wall through the floor slab, so the main wall is an important wall for the house to determine safety, so it cannot be dismantled. Looking at the thickness of the wall, if the wall is a brick wall and the wall thickness is 24cm, it is not recommended to remove it; Secondly, in addition to looking at the thickness, you can also judge by knocking on the wall and listening to the sound, if the knocking sound is relatively thick and dull, it can probably be judged as a load-bearing wall and cannot be removed. A load-bearing wall is a structural way in which a wall supports a roof.

It has a strong longitudinal bearing capacity and consists of single or double rows of steel bars inside. Gypsum board wall is currently very common - a kind of hard partition wall, the wall made of this material generally has a load-bearing function, so the removal of such a wall will not have much impact on the house, so such a wall can be removed. Load-bearing walls cannot be removed.

Many owners know that they can't be demolished, but what kind of wall is a load-bearing wall?

For example, like exterior walls, walls that are shared with neighbors, do not have prefabricated ring beams.

We usually look at the pattern between the houses and the houses above, the thicker walls are not moving. The kind of window sill with steel bars inside the wall cannot be removed, and if it is the kind of window sill that can be removed, it is also recommended to cut it with a cutting machine and use an electric drill.

Peel off the wall, do not hit with a sledgehammer, it is easy to cause damage to the wall, it may not be obvious at the time, and the wall paint is easy to crack in the later decoration.

If people remove the load-bearing wall in the design, it will not only destroy the pattern and integrity of the whole building, but also easily cause the collapse of the house.

brick-concrete structure. Exterior walls and sub-household walls cannot be demolished. The brick wall that will affect other residents and the safety of the façade cannot be removed. In fact, the brick wall of the brick and concrete structure should be demolished as little as possible. Sometimes the balcony is pressed against a brick wall.

Whether the wall of the home can be demolished can ask the property or the developer, the load-bearing wall must not be demolished, and the non-load-bearing wall can be renovated and demolished.

You can knock it with your hand, and if you think the sound is relatively dull, you can't disassemble it, because the inside is closed, and it is also made of latex paint.

Load-bearing walls, steel bars in walls, beams and columns in houses, counterweight walls, kitchens or bathrooms are all not removable, and the specific judgment methods are as follows:

Reinforcing steel in the wall: The reinforcing steel in the wall is like the bones of the human body, which plays a supporting role in the building. If the horizontal groove is opened deeply, it is easy to hurt the wall reinforcement. Therefore, it is recommended that it is best to open a vertical groove when walking hydropower, which can effectively avoid hurting the wall reinforcement.

Beams and columns in the house: The beams and columns in the room are mainly to bear the upper floor slabs, and removing the beams and columns will affect the load-bearing.

Counterweight wall: Generally, there are doors and windows on the walls of rooms and balconies, these doors and windows can be dismantled, but the walls below the windows cannot be moved, which is the counterweight wall. It plays the role of provoking the balcony like a weighing stone, and demolishing this wall will cause the load-bearing capacity of the balcony to decrease, and there is a danger of falling.

Kitchen or bathroom: The floor of the kitchen and bathroom needs to be made of waterproof layer, if the waterproof layer is damaged by demolition and modification, it is easy to cause leakage. Therefore, try not to move these places, if you do, you should check the waterproofing twice, and do a closed water test to make sure that there is no water leakage.

1. Note that only non-load-bearing walls can be demolished and modified.

Before decorating and demolishing, we must understand which walls can be demolished and which cannot be demolished, otherwise the consequences will be unimaginable. The only walls that can be demolished are non-load-bearing walls, and non-load-bearing walls are generally thin, about 10 cm thick, and these walls are generally indicated on the floor plan.

2. Pay attention to consider transforming the circuit pipeline.

Before dismantling, the direction of the transformation of the circuit should also be considered in detail. Generally, there are circuit pipelines in the wall, so be careful not to break the circuit due to barbaric construction. After all, the transformation of the circuit is a very watery part of the project cost, and it must be planned.

3. Add a new wall and select the material according to the situation.

High-rise buildings generally adopt a frame structure, that is, the external wall is load-bearing, the interior wall is generally a light structure wall, and the interior wall only serves as a partition, and the load-bearing support is very small. When you add a new wall, you generally use the same light wall such as cement board wall or gypsum board as the original, and you can also choose materials with better sound insulation or high cost performance according to your own situation.

Calculation method of wall engineering quantity

Solid brick walls, hollow brick walls and stone walls are calculated by volume according to the dimensions shown in the design drawings. Deducting the volume of door and window openings, manholes, empty rings, reinforced concrete columns, beams, ring beams, pick-up beams, lintels embedded in the wall, niches, pipe grooves, heating grooves, and fire hydrant boxes recessed into the wall.

The volume of beams, plates, purlins, skids, wooden flutes, edge wood, wood bricks, door and window heads, reinforced steel bars, iron parts, steel pipes and holes within a single area is not deducted. The volume of the waistline, eaves, roof, window sill line, tiger head bricks, and door and window covers protruding from the wall is also not increased, and the brick stacks protruding from the wall are incorporated into the wall volume.

First, look at the house plan information.

In the house plan drawing, the walls marked as black on the engineering drawing are load-bearing walls, and the walls marked as white are non-load-bearing walls. Generally speaking, non-load-bearing walls can be remodeled and demolished, and will not have a great impact on the construction of the house.

Second, look at the structure of the house.

From the point of view of the house structure, all the walls of the brick-concrete structure house are load-bearing walls. The exterior walls of the frame structure are load-bearing walls, and the internal walls are generally non-load-bearing walls.

3. Look at the grade of the house.

Low-rise residential buildings, bungalows and villas are made of brick and concrete, so the walls are basically load-bearing. High-rise elevator buildings and western-style houses have many frame structures.

Fourth, look at the thickness of the wall.

From the perspective of wall thickness, non-load-bearing walls are relatively thin, and the thickness is generally about 10 cm. When identifying the thickness of the wall, the one that can hear a crisp and loud echo when you knock on the wall is a light wall, that is, a non-load-bearing wall. The thickness of the load-bearing wall is generally more than 24 cm, and there is no great echo when struck.

5. If you don't know what the structure of your house is, and you want to demolish and modify the wall, you can find an experienced decoration company to carry it out. It is also necessary to understand the structure of the house before making a decision, so as not to dismantle and rebuild it at will into unnecessary safety problems. In addition, when the load-bearing wall is demolished and modified, it must be filed with the property management department, and the construction can only be carried out after approval.

The main judgment methods are as follows:

Looking directly at the load-bearing structure of the house, it is known that the load-bearing wall of the black entity is not modifiable, and the other walls can be transformed as long as they are not separated from the outside world or from neighbors;

The sound of striking with a hammer is known, the sound is thick is the load-bearing wall, and the sound is empty;

It is known that it is easy to drill through the partition wall, and the load-bearing wall is the opposite;

electronic detector because there is a rebar metal material in the load-bearing wall;

When <> a new house is renovated, how to determine which walls can be removed? Can not be distinguished purely from the wall material, even if the brick wall, there is also a load-bearing or breeding effect, mainly depends on the type of house structure, brick concrete, frame and shear wall structure is more common, must be based on the site structure and beam and column distribution to analyze the wall role, to see whether it can be demolished or partially demolished. The current building can be demolished as long as it is not reinforced concrete, and the full shear wall structure can not completely dismantle a certain section of the wall, only a small part.

Many of the brick-concrete structures of old houses are load-bearing walls, and only part of the doorways and windows can be removed. Of course, it is best to have a reference for the structural drawings of the building if it needs to be demolished, and do not be capricious, otherwise the consequences will be really serious.

Modern houses are framed and can be decorated at will. Theoretically, it is best not to smash the load-bearing wall marked on the manual of the commercial house. Looking at the house simply, if the thickness of the wall is the width of a brick, then such a basic can be smashed.

The width of the wall is the length of a brick, then it is basically a load-bearing wall, it is best not to smash yourself to knock on the wall, you can compare the sound, if the sound is very heavy, it is basically a load-bearing wall, not dismantled. But to distinguish the sound of the hollow drum on the wall you are knocking, it is best to knock on the whole wall in a large area to eliminate the sound of the hollow drum, some people will not be able to distinguish the sound of the hollow drum! The best way is to find a property and ask for a drawing, and the deepening of the black frame is the load-bearing wall, which cannot be removed!

First of all, it is necessary to look at the foundation of the original wall, for example, to see whether there are hollows, cracks, and peeling on the wall. If these problems occur, if you brush directly on the original old latex paint on the original basis, it is easy to fall off the original old wall skin directly after brushing, and the project will be bigger at that time, and you have to rework it again, and then you will have to shovel off the wall skin again, and then brush it again. Therefore, the decisive condition is the quality of the first wall treatment.

The load-bearing wall can not be demolished, the wall is mixed with cement, there is no way to dismantle it, only the wall is made of red bricks, so the wall can be demolished, they will not have much impact on the structure and load-bearing of the overall house, the general pattern of the new house is fixed, the property is not allowed to be demolished, at this time it is necessary to negotiate and communicate with the property and the housing authority.

You can look at the building structure diagram in advance, and you can also ask professional personnel to go to the home to see which ones can be demolished, and you must file with the property department before demolition. The destruction of the load-bearing wall will affect the load-bearing of the floor, which can be patted with your hands, there is a crisp echo, and the sound is very muffled.

If it is just a partition and the roof is not connected to the top, it can be disassembled, see if the wall is particularly thick, whether it plays a fixed role in the house, there are connection points above, and the occupied area of the wall is very small.

Lighter walls can be demolished, as long as they are not load-bearing walls, they can be removed by communicating with the property, and load-bearing walls are heavier.

If you ask what the first process of construction in home renovation is, some owners will choose to tear down the wall. Indeed, the demolition of the wall is the first link in many home decoration, the reason why this link frequently appears in the process of home decoration, there are two reasons: one is that the owner of the house pattern is said to be small, can only find a way to increase the practical area from the interior, but this is the rational use of space, this is not, there is such an owner's home, the family lives on the 6th floor, in order to expand the door opening between the living room and the balcony during the decoration, the equipment wall of the air conditioner is smashed with a hammer.

Look at the thickness of the wall non-load-bearing wall.

All are relatively thin, generally around 10 cm thick. If you pat it with your hand, it is a light body wall with a crisp big echo, and the load-bearing wall is generally 240 cm or more thick, and there should not be too much sound when you knock it.

Part of the non-load-bearing wall After the building is built, the wall that rises after the span is relatively large, structurally speaking, this kind of wall belongs to the non-load-bearing wall, but it plays a great supporting role in the house, and it can not be demolished and modified at will. For the non-load-bearing wall under the concrete beam, whether it is the decoration of a new house or the renovation of an old house, it will face the problem that the wall needs to be removed.

The modification was made to ignore the more important element of renovation safety. Here is a summary of the front-line demolition workers for you.

I think you should first find the structural drawings and architectural drawings to know the specific operation, the balcony from the diagram should be the appropriate bricklaying of the beams, no problem, the use of lightweight bricks.

It is better to reduce the load. The two dotted lines should be the air conditioning board, generally the load value of the pick plate is limited, the thickness of the plate is generally small, can not be distinguished purely from the wall material, even if the brick wall, there is also a load-bearing or breeding effect, mainly depends on the type of house structure, brick concrete.

frame and shear wall structures.

It is more common, and the role of the wall must be analyzed according to the on-site structure and the distribution of beams and columns to see whether it can be demolished or partially demolished.

No, because when the building is built, any wall is used as a support, and random demolition may cause collapse.

No, because your house in the building is indeed your house, but it affects the safety of the whole building, and you can't tear down the walls yourself, it's too dangerous.
