Houses have load bearing walls, how can you tell which wall in the house is load bearing?

1.It can be interpreted by the house drawings, and the general load-bearing walls are drawn with thick solid lines, and the non-load-bearing walls are drawn with thin dotted lines.

2.It can be distinguished by the sound, the load-bearing wall does not make much sound when struck, but if the knocking sound is crisp, it means that it is a non-load-bearing wall.

3.Distinguish by thickness. The load-bearing wall is thicker, about 24 cm, and the vice versa is not.

4.In terms of location, the exterior wall is a load-bearing wall, and the non-load-bearing wall is a partition wall.

Judging by the sound of knocking on the wall, if the sound of knocking on the wall is dull, then it is a load-bearing wall, and if the sound of knocking is empty, then it is not a load-bearing wall.

1. Listen to the sound to distinguish

To identify a load-bearing wall, you can tap the wall by hand, a non-load-bearing wall will produce a crisp echo, and a load-bearing wall will make a dull sound.

2. Distinguish from the combination of beam and wall

Generally, the load-bearing wall is closely combined between the wall and the beam, and the non-load-bearing wall is the method of diagonal brick arrangement.

3. Identification according to the structure of the house

Generally speaking, the walls of brick-concrete houses are load-bearing walls, and the internal walls of frame-structure houses are generally not load-bearing walls.

4. According to the material of the wall tiles:

Generally, the wall of standard brick is a load-bearing wall, and the aerated brick is a non-load-bearing wall.

5. Distinguish according to the part of the wall

Generally speaking, exterior walls and walls shared with neighbors are load-bearing walls, while most of the partition walls in the bathroom, pantry, kitchen, and hallway of the home are non-load-bearing.

Load-bearing walls support the floor slabs above the floor and are connected to the exterior walls to help support and ensure the sturdiness of the building. There are evenly stressed steel bars to support the entire building to form a state of equilibrium. When the bracket is removed and modified, the uniform stress will be destroyed, and over time, deformation, cracking, and even collapse will occur.

If the load-bearing wall is removed, unexpected cracks will appear in the upper or exterior walls. As the cracks increase, the floor slab will slowly collapse; Even if it doesn't collapse, it will shorten the life of its building and accelerate its likelihood of becoming a dangerous building.

Depending on the size, height, newness, and density of the building, the timing of the problem varies. A load-bearing wall is a wall that supports the weight of the upper floor. The drawing shows a black wall.

If it is torn down, the entire building structure will be destroyed; A non-load-bearing wall is a wall that does not support the weight of the superstructure and only serves to separate the rooms. On the engineering drawings is a hollow wall. Whether or not there is such a wall does not have a great impact on the building structure and will not have an impact on the building structure.

The best way to distinguish a load-bearing wall is to look at architectural drawings, but sometimes the relevant data is not available at hand. Walls with a thickness greater than 240mm are load-bearing walls. Some walls that do not distinguish thicknesses, exterior walls, and walls that are shared with neighbors are mostly load-bearing walls.

Generally, brick-concrete structure houses, except for bathroom and kitchen partition walls, are load-bearing walls.

The part with thick solid lines and no prefabricated ring beams is a load-bearing wall, and judging by the sound, this wall can be knocked down. Judging from the sound, if there is not much sound when striking, in terms of thickness, the thickness of the thick wall is generally about 24 cm. From the point of view of location, the exterior wall part is generally a load-bearing wall.

Load-bearing walls take on the task of supporting the weight of the building. It is a large and complex job, from piling, trenching, foundations, cast-in-place beams, columns and building walls, bearing walls to bear the responsibility of supporting the building.

First, judging by the drawings, the part that is generally drawn with thick solid lines and does not have prefabricated ring beams is the load-bearing wall. The second is to judge by sound, you can knock on the wall, and judge by the sound it makes, if it doesn't make a big sound when knocking, it is a load-bearing wall, and it is not very crisp. Third, the thickness of the heavy wall is generally about 24 centimeters.

Fourth, judging by the location, the part of the exterior wall is generally a load-bearing wall. Load-bearing walls cannot be smashed.

In the process of home decoration, we must distinguish the city wall, generally speaking, the developer will give a clear sign, the load-bearing wall can not be smashed, otherwise it will affect the entire wall structure.

When handing over the house, the developer will explain clearly that each wall is a load-bearing wall, and a heavy wall cannot be smashed, and if there is a problem, it is necessary to bear the corresponding responsibility, and the consequences are very serious.

Nowadays, many families like to change the layout when decorating. The so-called layout transformation is actually the operation process of demolishing walls, smashing walls, and then repairing walls. But when we tear down and build walls, we can't tear them down and change them at will.

Look at the architectural drawings. When we buy a house, we basically give us a set of architectural drawings for the house. In this set of architectural drawings, we will illustrate the function of each room, each wall, windows, doors, etc. in our home.

Therefore, we can distinguish which walls are load-bearing walls and which are not, based on this set of drawings. Annotation methods for certain structures in architectural drawings: Load-bearing wall annotation is a deepening annotation method.

Non-load-bearing walls are usually represented by a drawn frame. The window takes the representation of adding a horizontal line in the frame. Draw the shape of the door at the door.

So after we get the drawings, we first look at this ** paper and get familiar with the structure of the whole wall. This is good. Most people can see it.

We have walls around and inside our house, and the deepening part is load-bearing wall. The second way is to judge empirically. The first, commonly used method of judgment is also very useful.

First of all, we can conclude that the exterior wall of the house is a wall that is in contact with the outside world, which is basically a load-bearing wall. In addition, the removal and replacement of facades is not allowed even if they are not load-bearing walls. The second way is to listen.

We can hit the wall with a small hammer or the palm of our hand. If the percussion sound is low and quiet, it can basically be concluded that the wall is load-bearing. If we knock on the door loudly and can clearly hear the buzzing, then the wall is basically a back wall, which is a brick wall.

It would be inaccurate if it was an old house, because many old houses were made of brick and concrete. All brick-concrete walls were basically built after completion. These post-masonry walls are load-bearing and are not allowed to be removed and remodeled.

Therefore, for brick-concrete structures, we should not remove and replace the walls. The other is the simplest frame structure. Although there are very few architectural frame structures nowadays, they do exist.

The dismantling and modification of the frame structure is actually very simple. We just need to find the column at home. Make sure that the column can't be removed and the rest can basically be removed.

It can be judged according to the map on the title deed, and it can also be judged according to the thickness of the wall, and the load-bearing wall can never be removed.

It can be judged by the sound, if there is a relatively large echo when knocking on the wall, it means that it is not a load-bearing wall; Load-bearing walls cannot be removed, as they maintain the stability of the house's structure.

If you want to see which is the load-bearing wall in the house, you should look at its pattern and structure, the first point is that the load-bearing wall will definitely affect the quality of the house if it is removed, and the second point is likely to collapse, so do not demolish it randomly.

1. View engineering drawings: people will find the drawings of the house when buying a house, if there is a property, you can find the property to distinguish between the load-bearing wall and the non-load-bearing wall, the black wall on the engineering drawing represents the load-bearing wall, and the thick solid line part in the construction drawing and the wall under the non-load-bearing beam in the ring beam structure are load-bearing walls.

2. Listen to the sound: The easiest way to identify a load-bearing wall is to tap the wall with your hands. The light wall (non-load-bearing wall) has a crisp echo, while the sound of knocking on the load-bearing wall is basically dull.

3. Look at the brick structure: all the two brick walls and one brick vertical wall of the brick-concrete structure house are load-bearing walls. Aerated bricks are non-load-bearing walls. Walls with "empty sounds" when struck are non-load-bearing walls.

The way to judge whether a wall is a load-bearing wall is to look at the thickness of the wall, listen to the sound, look at the wall and beams, and so on.

1. Look at the thickness of the wall

According to national regulations, the thinnest thickness of the load-bearing wall is 160mm, and the general thickness of the load-bearing wall is 240mm, if the thickness of the wall is less than 150mm, it can basically be judged that it is not a load-bearing wall.

2. Listen to the sound

The load-bearing walls are made of solid bricks, while the infill walls are made of aerated bricks. Therefore, you can use an instrument to knock on the wall, if the sound is thick and dull, and there is no residual sound, it is generally a load-bearing wall, if the sound is loud and crisp, and there is an aftersound, it is a non-load-bearing wall.

3. Look at the walls and beams

The load-bearing wall is the fulcrum that supports the beams, so you can look at the load-bearing walls under the beams. If the bends of the beam walls are closely connected, they can be judged to be load-bearing walls.

Consequences of openings in load-bearing walls:

1. The force of the load-bearing wall is calculated by the designer, and the force is uniform, if the hole is opened in the load-bearing wall in the later stage, the bearing capacity of the load-bearing wall will be destroyed, thereby affecting the stability of the building, and causing the seismic resistance of the house to decline. If you have to make holes in the load-bearing wall, you must have the design unit redesign, such as using carbon fiber bonded steel for reinforcement, and the demolition and reinforcement must be completed by a professionally qualified construction team.

2. The load-bearing wall is used to support the weight of the upper part of the house, and the weight of the building is slowly transmitted downward through the load-bearing wall until the soil. If a hole is made in the middle of the load-bearing wall, it will hinder the transmission of this force, which will cause the two sides of the hole to slowly open and crack, and even cause collapse.

3. The opening of the load-bearing wall will expose the steel bar, and the steel bar will slowly rust after being exposed to the air for a long time. If the air is humid, the rust of the steel bar will be more serious, and the rust will slowly rust into the inside of the steel bar, which will destroy the stability of the wall and cause potential safety hazards such as the wall falling off.
