What is a load bearing wall What is a non load bearing wall How to identify

load-bearing walls. The load-bearing wall refers to the wall that supports the weight of the upper floor in the masonry structure, which is a black wall on the engineering drawing, and will destroy the entire building structure if it is knocked out; Non-load-bearing wall refers to the partition wall does not support the weight of the upper floor, only plays the role of separating one room from another, and is a hollow wall in the engineering drawing, and whether there is this wall has no big impact on the building structure.

The load-bearing wall is scientifically calculated, and if the load-bearing wall is perforated and decorated, it will affect the stability of the building structure and change the system of the building structure. It is a very dangerous thing, and it is better not to change the load-bearing wall for non-professional designers.

Be careful!

This paragraph] how to identify load-bearing walls.

Whether the wall is a load-bearing wall depends on whether the wall itself is load-bearing.

The thick solid line part in the construction drawing and the wall under the non-load-bearing beam in the ring beam structure are all load-bearing walls. The on-site inspection of the wall without prefabricated ring beams must be load-bearing walls. Non-load-bearing walls are generally marked with thin solid lines or dotted lines on the drawings, and are walls made of lightweight and simple materials, while non-load-bearing walls are generally thinner and are only used for partition walls.

Generally speaking, all the walls of a brick-concrete house are load-bearing walls; The walls inside a frame structure house are generally not load-bearing walls. Of course, when it comes to the structure of the house itself, to determine whether the wall is a load-bearing wall, it should be determined after carefully studying the original architectural drawings and going to the actual site investigation.

When personal renovation, you can simply distinguish between load-bearing walls and non-load-bearing walls by combining the following points:

1. Distinguish from the structure of the house

Generally speaking, all the walls of a brick-concrete house are load-bearing walls; The walls inside a frame structure house are generally not load-bearing walls.

2. From the grade of the house: the general low-end residential buildings and villas are made of brick and concrete. The high-end ones are more frame structures.

3. Distinguish from the material of wall tiles: the wall of general standard brick is a load-bearing wall, and the aerated brick is a non-load-bearing wall.

4. From the thickness of the wall: the 150mm thick partition wall is a non-load-bearing wall, such as the bathroom and kitchen.

5. According to the combination of the beam and the wall, it is generally the load-bearing wall that is closely combined between the wall and the beam; The method of diagonal bricks used is a non-load-bearing wall.

Teach you 60 seconds to distinguish between load-bearing and non-load-bearing walls.

Generally speaking, black walls are load-bearing walls and white walls are non-load-bearing walls.

Here are four easy ways to distinguish a load-bearing wall from a non-load-bearing wall:

1. Judging by drawings: The best way to distinguish the load-bearing wall is to look at the architectural drawings, and the load-bearing wall will be marked.

2. Judging by sound: knocking on the wall, there is a crisp echo, it is a light wall, and the load-bearing wall should not have too much sound.

3. Judging by thickness: the wall of the non-bearing heavy wall in the floor plan is obviously thinner than the load-bearing wall, generally about 10 cm thick. Load-bearing walls are thicker, and their thickness is generally around 24 cm.

Generally speaking, when the load-bearing wall is a brick wall, the thickness of the structure is 24cm, the thickness of the external wall structure in the cold area 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.

4. Judging by the location: the exterior wall is usually a load-bearing wall, and the wall shared with the neighbors is also the same. Typical non-load-bearing walls are used in bathrooms, pantry, kitchens and hallways.

In home decoration, design to house demolition, buried bucket then must not be able to bypass the load-bearing wall, the home wall is mainly divided into load-bearing walls and non-load-bearing walls, load-bearing walls are a very important part of the house structure, so this part must not be demolished in the process of transformation, but many people can not distinguish load-bearing walls and non-load-bearing walls, let's take a look at how to distinguish between load-bearing walls and non-load-bearing walls.

1. What are load-bearing walls and non-load-bearing walls?

1. Load-bearing nuclear search wall.

As the name suggests, it refers to a type of wall that supports the weight of the upper floor in a masonry structure. This type of wall is represented in black above the drawing. If the load-bearing wall is removed, the entire building structure will be destroyed; The load-bearing wall is after some careful and scientific calculations, and if the load-bearing wall is perforated and decorated, it will affect the stability of the building structure and change the system of the building structure.

2. Non-load-bearing walls.

It refers to the wall that does not support the weight of the upper floor, and only plays the role of separating one room from another.

2. How to distinguish between load-bearing walls and non-load-bearing walls?

1. Look at the drawings to judge: the most direct and simple way to identify the load-bearing wall is to look at the architectural drawings. On architectural drawings, load-bearing walls are marked.

In construction drawings, the thick solid line section 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 non-load-bearing walls are generally thinner and are only used to partition the walls.

1. Judge by tapping on the wall: When we knock on the wall, we can judge by sound. When there is a crisp big echo, it is a non-load-bearing wall, and it is a load-bearing wall without too much echo grinding sound.

2. Judge according to the location: the general exterior wall and the common wall with the neighbor belong to the load-bearing wall. The walls of toilets, pantry, kitchens and corridors are generally non-load-bearing.

3. Judging according to the thickness of the wall: Generally speaking, the load-bearing wall is much thicker than the non-load-bearing wall, the thickness of the load-bearing wall is generally about 24 centimeters, and the thickness of the non-load-bearing wall is about 10 centimeters. In addition, due to the different materials, the thickness of the load-bearing walls of brick walls is 24 centimeters, and the thickness of the load-bearing walls of concrete structures is 16 or 20 centimeters.

The thickness of the non-load-bearing wall is in.

Eight, ten, twelve centimeters.

Here are the main differences between the two.

First, the walls are different.

1. Load-bearing wall.

A load-bearing wall is a wall that supports the weight of the upper floors.

2. Non-load-bearing walls.

A non-load-bearing wall is a wall that does not support the weight of the upper floor.

Second, the material of the wall tiles is different.

1. Load-bearing wall.

Load-bearing walls are generally made of standard bricks.

2. Non-load-bearing walls.

Non-load-bearing walls are generally made of aerated bricks.

Third, the combination of beams and walls is different.

1. Load-bearing wall.

The load-bearing walls are tightly integrated with the beams.

2. Non-load-bearing walls.

The non-load-bearing wall adopts the method of diagonal bricks.

Fourth, the structure of the house is different.

1. Load-bearing wall.

All walls of a brick-concrete house are load-bearing walls.

2. Non-load-bearing walls.

The walls inside a frame structure house are generally not load-bearing walls.

1. Load-bearing wall.

The load-bearing wall refers to the wall that supports the weight of the upper floor, which is a black wall on the engineering drawing, and will destroy the entire building structure if it is knocked out; The non-load-bearing wall refers to the wall that does not support the weight of the upper floor, and only plays the role of separating one room from another.

2. Distinguish between load-bearing walls and non-load-bearing walls.

1. 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, and the non-load-bearing walls can be transformed and demolished, which will not affect the housing construction.

2. Look at the structure of the house.

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

3. Look at the thickness of the wall.

Non-load-bearing walls are relatively thin, generally around 10 cm thick. If you pat it with your hand, it is the light body wall that has a crisp echo, while the load-bearing wall is generally more than 24 cm thick, so it shouldn't have much sound when you shoot it.

4. Look at the material of the brick wall to judge.

Generally, the aerated block bricks are non-load-bearing walls, and the ordinary standard wall tiles are load-bearing walls.
