How can you tell if a wall is load bearing? How can I tell?

The walls of the building are divided into load-bearing walls and non-load-bearing walls. In the building structure, the load-bearing wall plays the role of supporting the wall and resisting earthquakes. In the decoration, it is inevitable to knock on the wall, and the load-bearing is not beaten, and if it is knocked off, it will destroy the building structure of the entire floor.

It can also affect the stability of the foundation, which is a very dangerous behavior. Therefore, it is necessary to distinguish between load-bearing walls.

First, the load-bearing wall can be distinguished from the thickness. The wall of the load-bearing wall is generally thick, if it is on the spot, you can use a ruler to measure it, generally the thickness of more than 200 mm, are load-bearing walls, or use your hands to knock on the wall, the echo is very small, the sound is muffled, and the brittle is the load-bearing wall. Walls that are not load-bearing are generally no more than 150 mm, and the two are still very different.

Second, from a structural point of view. Many houses will use beams and pillars instead of wall load-bearing. The walls under the sorghum are basically not load-bearing walls.

There is also a brick and concrete structure house, where all the walls are load-bearing. The interior walls of a frame structure house are rarely load-bearing, and if there are pillars protruding from the walls or corners of the interior walls, then there is a high probability that it is a frame structure. There are some walls that can be distinguished from the arrangement of bricks, and the wall that is combined with the beam, if the top brick is used in the diagonal way, it is a non-load-bearing wall.

Third, from the original drawings. Every industry has a professional way of expressing it. If you are still unsure, you can ask the property of the community, or the relevant management personnel, if you are looking for a designer team to design, they will also tell you the location of the load-bearing wall.

The load-bearing wall can still be well distinguished, the fastest way is to distinguish from the thickness and the sound of knocking, before not sure whether it is a load-bearing wall, do not blindly knock on the wall, in the decoration of the wall transformation is not to remove the load-bearing structure, if the demolition will be ordered by the relevant departments to rectify, and will be fined.

Knock on the wall, if the sound is particularly dull or there is not too much sound, it means that it is a load-bearing wall, which can be judged by the position of the wall, and the load-bearing wall will be thicker than other walls, or the developer will give drawings when buying a house, which can be judged whether it is a load-bearing wall.

It can be judged by appearance, because load-bearing walls are generally very thick, much thicker than ordinary walls, and this method of judgment is also very reliable.

If the floor of your house is 6 or 7 floors, then you can see how thick the wall in the house is, if it is 240 cm or larger than 240 cm, then the wall is a load-bearing wall.

If you have a floor plan, just look at the floor plan, the dark wall on the map is the load-bearing wall, and the light-colored white wall is the non-load-bearing wall, just like this. If there are no engineering drawings, friends can also communicate with the property in advance to confirm. There is no floor plan that can be confirmed as follows:

1. Listen to sounds.

Knocking on the wall, there is a crisp big echo, it is a light wall, while the load-bearing wall should not have too much sound.

2. Judge by location.

Exterior walls are usually load-bearing; The wall that is shared with the neighbors is too. Generally, the non-load-bearing walls of Shenchang are used in bathrooms, storage rooms, kitchens and corridors.

3. Look at the thickness.

The wall thickness of the non-load-bearing wall in the floor plan is obviously thinner than that of the load-bearing wall, generally about 10 cm thick. The load-bearing walls are all thicker, second only to the exterior walls. The thickness is basically a load-bearing wall, and its thickness is generally about 24 cm.

Generally speaking, when the load-bearing wall is a brick wall, the structural thickness is 24cm, the thickness of the external wall structure in cold areas is 37cm, the thickness of the concrete wall structure is 20cm or 16cm, and the thickness of the non-load-bearing wall is 12cm, 10cm, and 8cm.

1. Brick-concrete structure.

Brick-concrete structure refers to the load-bearing structure of walls, columns and other load-bearing buildings made of bricks or blocks vertically, and beams, floor slabs and roof panels made of reinforced concrete in the transverse direction. Its residential load-bearing structures are floor slabs and walls. Most of the old houses use this structure, and the height of the building does not exceed 6 floors.

2. Frame structure.

Frame structure refers to the structure of beams and columns connected by rigid or hinged joints to form a load-bearing system. Both the transverse and vertical are frame structures consisting of beams and columns to bear loads. The walls of the frame structure of the house are not load-bearing, and only play the role of enclosure and separation.

It is suitable for the construction of houses with no more than 15 floors, and most of the walls are not load-bearing.

3. Frame shear structure.

The frame shear structure is a combination of the frame structure and the shear wall structure. In addition to the frame arrangement, part of the shear wall is added in the structural layout, that is, the beams and columns in the frame structure are replaced by reinforced concrete wall panels. The structure of some of the newly built high-rise residential buildings.

Suitable for buildings with more than 10 floors. Generally speaking, more than 80% of the frame-shear structure is borne by shear walls under horizontal loads.

In the process of decoration, it is inevitable to smash the wall, the structure of each house is different, so before smashing the wall, you need to distinguish which is the load-bearing wall, the load-bearing wall is absolutely not destroyed and can be smashed, so how to judge whether it is a load-bearing wall? If you want to know more, you may wish to take a look with us!

1. How to judge whether it is a load-bearing wall.

1. Judging by drawings.

First of all, look at the drawings of building construction, the part drawn with thick solid lines in the drawings and the walls under the non-load-bearing beams in the ring beam structure belong to the load-bearing walls. Generally, the drawings of non-load-bearing walls will be marked with thin solid lines or dotted lines, which are lightweight and simple walls, which are generally relatively thin and are only used as partition walls.

2. Judge by sound.

You can knock on the wall, judging by the sound it makes, if it makes a crisp echo when it is tapped, it means that it is a light wall, and if it does not make any too loud noise, it is a load-bearing wall.

3. Judging by thickness.

It can be clearly seen in the floor plan of the house that the thickness of the load-bearing wall is obviously thicker than that of the non-load-bearing wall, and the thickness of the difference is generally about 10 cm. The load-bearing walls are relatively thick, and the thickness of the load-bearing walls is generally 24 cm on the left and on the right. Generally, the structural thickness of the load-bearing wall is 24cm, the thickness of the external wall structure in some cold areas is 37cm, the thickness of the concrete wall structure is 20cm or 16cm, and the thickness of the non-load-bearing wall is 12cm, 10cm, 8cm.

4. Judge by location.

It can also be judged by the location, the general part of the exterior wall is a load-bearing wall, and the wall shared with the neighbor is also a load-bearing wall, and the wall surface of the general non-load-bearing wall is: bathroom, storage room, kitchen and aisle.

Summary: The above is for you to share how to judge whether it is a load-bearing wall, I believe that you also have a corresponding understanding after reading the above points, if you need to know more about relevant information, please continue to pay attention to Qeeka Home**, will answer for you one by one.

1. View engineering drawings: Under normal circumstances, 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 represents the load-bearing wall in the engineering drawing, 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. Non-load-bearing walls are generally marked with thin solid lines or dotted lines on the drawings, and are made of lightweight, simple materials, while non-load-bearing walls are generally thinner and only used for partition walls.

This is the most straightforward way to discern this.

2. Listen to the sound: Usually 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. Generally, aerated bricks are non-load-bearing walls. Most of the walls that have an "empty sound" when struck are non-load-bearing walls.

4. Look at the thickness of the wall: 150mm thick partition wall is a non-load-bearing wall, such as more bathrooms and kitchens, and 240mm and above thickness is a load-bearing wall.

5. According to the combination of the beam and the wall, it is the load-bearing wall that is closely combined between the wall and the beam, and the non-load-bearing wall that adopts the oblique brick method. The load-bearing wall mainly depends on the structure of the design, and the intersection of the two vertically intersecting load-bearing walls generally has seismic structural columns, and the skin can also be knocked off during construction, and the structure inside is judged.

6. According to the floor: the columns and concrete walls above 7 floors of the frame structure generally play a load-bearing role, and the structural columns and load-bearing walls of the brick-concrete structure below the 7 floors cannot be played.

What are the ways to determine a load-bearing wall?

1. First of all, the load-bearing wall is irrigated by cement and steel when building a high-rise building, and the load-bearing wall is the skeleton of the room, which must have been built a long time earlier than the post-repair wall.

2. One of the easiest ways is to see that the top of the room must be a load-bearing wall, and you can refer to the color of the top to identify the load-bearing wall of the room.

3. Before renovation, go to the property management office to get the building structure drawings of your house type. Distinguish by looking at the walls on the drawing. (Generally, load-bearing walls and non-load-bearing walls are marked with colors on the drawing, so they can be used with confidence).

4. Go to the house and knock on the wall. If the percussion is of the kind with a dull sound, it is a load-bearing wall. And the sound feels crisper than ordinary brick walls.

Of course, if you still can't judge this way, then use a more direct method. Knock off the stucco layer. If you see a brick after knocking it off, it's a brick wall.

If you see concrete or rebar, it's a load-bearing wall.

5. Finally, buy a steel bar detector for engineering. This one is the most straightforward.
