How do you know which wall in your home is load bearing?

Preliminary identification methods:

Generally speaking, all the walls of a brick-concrete house are load-bearing walls;

If the floor slab is on that wall, then the wall below must be a load-bearing wall.

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

The thick solid lines in the construction drawings are all load-bearing walls.

Non-load-bearing walls are generally marked with thin solid lines or dashed lines on the drawings, and are walls made of lightweight and simple materials; Non-load-bearing walls are generally thinner and are only used for partition walls. Some of them have a hollow sound.

However, nothing is absolute, and the final determination can only be made after careful study of the original architectural drawings and actual investigation of the site.

If it is an old house, it is generally a brick-concrete structure, which is load-bearing and must not be smashed. If you just bought a commercial house, now it is generally a frame structure or a frame-cut structure, whether the load-bearing wall has to look at the drawings. Or you can remove a small piece of cement mortar surface layer on the wall to see if it is brick or concrete, brick is not a load-bearing wall, concrete is a load-bearing wall.

You can see the thickness of the wall. If it is a concrete wall, it is all load-bearing walls, if it is a brick wall, it is divided according to the thickness, and the general non-load-bearing walls are only 10 cm thick.

The easiest way is to see if there is a plan drawing on the sales contract, and the wall shown by the black entity is a load-bearing wall, or ask the developer if it is really not good, let the force smash the wall locally, see if there is a steel bar in the wall, and there is a load-bearing wall.

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.

A load-bearing wall is a wall made of reinforced concrete that is upside down to carry the weight of a house.

There are three ways to distinguish a load-bearing wall:

1. Look at the structural plan of the house.

The structural plan is generally filled with black and is a load-bearing wall.

2. Look at the thickness of the wall.

Generally, the thickness of the brick wall is: 14 cm, 22 cm thick, and the thickness of the load-bearing wall is thicker than the brick wall, at least 5 cm thicker than the brick core calendar, and at most more than 15 cm, which depends on the overall structure.

3. Chisel open the wall to view.

Chisel the wall more than 3 cm to see that the wall is concrete or there are steel bars exposed, and it is a load-bearing wall.

1.The standard thickness of the wall.

The thickness of the brick wall is based on the length of China's standard clay bricks, and the current specifications of clay bricks in China are 240mm 115mm 53mm (length, width and thickness). Together with the thickness of the ash joint of 10mm, the specifications of the bricks form a relationship of length, width and thickness = 4 2 1.

2.The current wall thickness is determined based on the length of the bricks.

The commonly used ones are the following:

1) Half-brick wall: the drawing is marked as 120mm, and the actual thickness is 115mm;

2) A brick wall: the drawing is marked as 240mm, and the actual thickness is 240mm;

3) One brick and a half wall: the drawing is marked as 370mm, and the actual thickness is 365mm;

4) Two brick walls: the drawings are marked as 490mm, and the actual thickness is 490mm;

5) 3 4 brick wall: the drawing is marked as 180mm, and the actual thickness is 180mm.

3.The main classification of walls.

The wall mainly includes load-bearing walls and non-load-bearing walls, which mainly play the role of enclosure and separation of space. The wall of the wall bearing structure building is integrated with the load-bearing and enclosure, and the function of the building wall of the skeleton structure system is to enclose and separate the space. The wall should have sufficient strength and stability, and have the ability of heat preservation, heat insulation, sound insulation, fire prevention and waterproofing.

There are many types of walls, including mono-material walls and composite walls. It is an important task of building structure to comprehensively consider the factors such as enclosure, load-bearing, energy saving, and aesthetics, and design a reasonable wall scheme.

4.How to identify load-bearing walls in your home.

1) The most direct and intuitive way is to look at the drawings, the black 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. This one is the most accurate.

2) Judging by the thickness, the thickness of the load-bearing wall is generally about 24 cm, and the thickness of the non-load-bearing wall is about 10 cm.

3) Listen to the sound to judge, knock on the wall, there is a crisp echo, it is a light wall, and the load-bearing wall is not too loud.

4) Judging by the location, the exterior wall is usually a load-bearing wall; The wall that is shared with the neighbors is too. Typical non-load-bearing walls are used in bathrooms, pantry, kitchens and hallways.

To put it simply, floor slabs are supported on structural components such as load-bearing walls and beams. In our house, the weight of the floor slab, the weight of the furniture, etc., should be transmitted to the load-bearing wall and structural beam through the floor slab, and then to the load-bearing wall or structural column below through the load-bearing wall and beam, and then to the foundation. The structural skeleton that forms the whole house, just like the skeleton of the human body, is an important part of determining the safety of the whole house.

First, there are engineering drawings.

The walls marked as black on the drawing are load-bearing walls, and the light-colored white walls are non-load-bearing walls.

Second, there are no engineering drawings.

1. Look at the structure.

In general, there are fewer frame structures, because the existing second-hand houses are generally mixed structures.

2. Look at the thickness of the wall.

The load-bearing wall is a brick wall, that is, 240 thick, with plastering and whitewashing, etc., generally around 300 friends. Non-load-bearing walls are generally half brick, i.e. 120 thick. However, it is not excluded that some non-rotten round load-bearing walls are made thicker.

3. Look at the material.

Looking at the material of the wall, hollow brick masonry is not a load-bearing wall, while concrete is generally a load-bearing wall.

4. Look at the beam. Look at whether there is a beam above the wall, and if there is a beam, the thickness of the beam is very relevant. Beams are divided into main beams and secondary beams. The beam section of the main beam is larger, that is, the beam is thicker. The walls underneath are mostly load-bearing walls.

In general, all walls of a brick-concrete house are load-bearing walls. The interior walls of a frame structure house are generally not load-bearing walls.

Main differences: First, the wall tiles are different.

1. Load-bearing wall.

The bricks used for load-bearing walls are standard bricks.

2. Non-load-bearing walls.

The bricks used for non-load-bearing walls are aerated bricks.

Second, the combination of beams and walls is different.

1. Load-bearing wall.

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

2. Non-load-bearing walls.

The walls and beams of the load-bearing wall are obliquely arranged with bricks.

3. The sound of knocking on the wall is different.

1. Undertake the wall of filial piety.

When you hit the wall, there is no echo.

2. Non-load-bearing walls.

When you hit the wall, there is a crisp big echo.
