What is the wall thickness standard? What is the general thickness of the wall?

1. Load-bearing wall.

There is generally no specific standard for the thickness of the load-bearing wall, but an important indicator to measure the load-bearing wall is that the load-bearing wall must meet the strength, fire prevention and use requirements, which are reflected in the thickness standards of the load-bearing wall of the house stipulated by the state.

Second, the thickness standard of the new load-bearing wall.

The first thing you need to know is that the newly built so-called load-bearing wall is generally called a shear wall. Of course according to JGJ3-2002, 2007 printed edition.

Article 7, short limb shear wall.

The interface thickness shall not be less than 200mm

Other general shear walls.

The first and second level seismic requirements, the bottom reinforcing part should not be less than 1 16 of the floor height or the unsupported length of the shear wall, and not less than 200mm; The data for other parts is 1 20,160 mm

The data for a shear wall without end posts or wing walls are: bottom reinforcement 1 12,180mm; Other parts 1 15,120mm

The third and fourth seismic requirements, the bottom reinforcement part should not be less than 1 20 of the floor height or the unsupported length of the shear wall, and not less than 160mm; The data for other parts is 1 25,160 mm

Non-seismic requirements, should not be less than the height of the floor or shear wall without support length of 1 25, and not less than 160mm

The above are construction requirements, which cannot be met only by calculation.

3. How to identify the load-bearing wall in the home.

1. The most direct and intuitive way is to look at the drawings, the black thick solid line parts and ring beams in the construction drawings.

Structurally neutral. The walls under the load-bearing beams are all 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.

Load-bearing wall thickness standard.

3. Listen to the sound to judge, knock on the wall, there is a crisp big 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.

Do the math how much it will cost you to renovate your home

There is no unified standard for the thickness of the wall, it still depends on what kind of brick you choose, generally there are two kinds of bricks: perforated bricks and standard bricks. Standard size of perforated bricks: 240*115*90, standard size of bricks:

240*115*53。The thickness of the mortar during masonry is generally 10mm. The thickness of the brick wall meets the specifications of the brick.

The thickness of a brick wall is generally expressed in terms of brick length, such as half brick wall, 3 4 brick wall, 1 brick wall, 2 brick wall, etc. The corresponding thickness is: 115mm, (called 12 walls) 178mm, (called 18 walls) 240mm, (called 24 walls) 365mm, (called 37 walls) 490mm, (called 50 walls) wall thickness should meet the bearing capacity of the brick wall.

Generally speaking, the thicker the wall, the greater the bearing capacity and the better the stability. The thickness of the brick wall should meet certain requirements for thermal insulation, heat insulation, sound insulation and fire prevention. Generally speaking, the thicker the brick wall, the better the thermal insulation.

The above has made a detailed introduction to the two kinds of bricks, I hope my can help you, thank you.

Enter the area and get the decoration for free**].

The thickness of the interior wall of the commercial house is generally 90mm-120mm. If it is a load-bearing wall, it is generally about 24cm; If it is a non-load-bearing partition wall, it is generally around 12cm. Others, such as shear walls, vary in thickness, but are usually above 24 cm, and some even exceed 30 cm.

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.

Calculation of wall area.

The wall area algorithm is to multiply the length by the height to get the square number.

The top area is long * wide, the ground area is usually equal to the top area, in a small part of the attention to add the area of the door of the room, but do not deduct the partition wall, through the ground columns, buttresses, flues, ventilation ducts and other occupied surface, the baseboard is calculated according to the net perimeter, as for other different parts of the decoration with different materials, it can be calculated according to the area of the decorative surface. Some rooms have triangular, trapezoidal or curved parts, and the floor and top area can be calculated according to their area formula.

The wall thickness is 120mm mm, 220mm, 240mm, 370mm and other standards.

Among them, the frame structure of the house is generally a wall with a thickness of 240mm, while the outer wall of the brick-concrete structure is 370mm, and the sanitary partition wall is generally a wall with a thickness of 120mm and 180mm.

If the house has an insulation layer, its exterior wall may reach a thickness of 650mm, in fact, there is no fixed standard for the thickness of the wall, mainly depending on the bricks of the wall, only the wall thickness can meet the bearing capacity of the brick wall.

Interior walls can be built with materials

1. Red bricks. Red brick has always been one of the very traditional wall masonry materials in China, with a long history of construction, with the advantages of light weight, high strength, long service life, etc., and now it will be reinforced with steel bars, which is more quality assurance.

2. Lightweight bricks.

Although this material has a certain load-bearing capacity, it is not possible to hang heavy objects such as cabinets, unless the wall is reinforced with steel mesh and cement.

3. Cement pressure plate.

Cement pressure board is one of the more common materials in indoor wall decoration, it is made of fiber, cement and other materials, has a good fireproof, moisture-proof effect, but basically does not have sound insulation ability, bearing capacity is not enough.

4. Gypsum board.

Gypsum board is also a commonly used partition wall material, in the use of the keel needs to be laid first, in order to fix the gypsum board, ** is relatively low, and the construction is convenient, but the sound insulation, sturdy and other performance is poor.

The current wall thickness is determined by the length of the brick, and the following are commonly used:

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

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

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

2. Brick wall: the drawing is marked as 490mm, and the actual thickness is 490mm;

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

Other walls, such as reinforced concrete slab walls, aerated concrete walls, etc., should comply with the provisions of the modulus. When a reinforced concrete slab wall is used as a load-bearing wall, its thickness is 160mm or 180mm; When used as a partition wall, its thickness is 50mm. When the aerated concrete wall is used for the perimeter parapet wall, 200mm 250mm is commonly used, and when it is used for partition wall, 100mm 150mm is often taken.

The thickness of the wall tiles is the same as the length in the figure according to our standard. The current specification of combat bricks in our country is 240mm * 115mm * 53mm, which is (length * width * thickness), and the thickness of the ash seam is 10mm, which is also included. And the specification of brick forms the relationship that length is width = 4 2 1, and at the same time there are 4 brick length, 8 brick width, 16 brick thickness in the masonry of 1m3, so that the amount of bricks used in the masonry of 1m3 is 4 8 16 = 512 pieces, and the amount of mortar is used.

1. Half-brick wall: the standard thickness is 115mm;

2. A brick wall: the standard thickness is 240mm;

3. One brick and a half wall: the standard thickness is 365mm;

4. Two brick walls: the standard thickness is 490mm;

4 brick walls: the standard thickness is 180mm.

Wall (or wall, wall) is one of the most important elements of architectural design, which is used to enclose, divide or protect an area. According to whether the wall is load-bearing in the building or not, it is divided into load-bearing walls and non-load-bearing walls. A load-bearing wall is a part of the building structure that bears the weight of the buildings on it and in the vicinity, and cannot be removed for renovation or other reasons.

The wall has two functions: on the one hand, as the external maintenance structure of the building, it needs to provide sufficient excellent waterproof, windproof, thermal insulation and thermal insulation properties to provide protection for the indoor environment; On the other hand, the wall is the main means for the architect to divide the space to meet the requirements of the building function and space.

Almost all important building materials can be used to build walls: wood, stone, brick, concrete, metal, polymers and even glass.

The exterior wall of the old house used to be 500 walls, now the exterior wall of the house is 370 wall meters, and the interior wall is the kitchen and bathroom wall.

Generally there are 30 centimeters behind the wall. Normal courtyard walls.

37 cm, 24 cm, 18 cm, generally 24 cm mostly.

The minimum thickness of the load-bearing wall of the house stipulated by the state is 240mm.

The data of a zigzag shear wall without end posts or wing walls is that the interface thickness of the short limb shear wall shall not be less than 200mm. Level 2 seismic requirements: 20, should not be less than 1 2 of the floor height or shear wall unsupported length, and not less than 200mm:

The bottom is reinforced by 1 25, which is generally a shear wall.

According to JGJ3-2002, the bottom reinforcement should not be less than 1 2 of the floor height or the unsupported length of the shear wall.

Common brick-concrete structures are generally 240mm.

The frame structure is generally 180mm.

The minimum thickness of the shear wall is 200mm. The design is controlled by the axial compression ratio. Lightweight enclosure walls, infill walls, and partition walls are generally 200, and small partition walls in kitchens and toilets are also 90. (None of the above contains flour thickness).

Walls are an important part of a building. Its role is to load-bearing, enclose, or divide the space. The wall is divided into load-bearing wall and non-load-bearing wall according to the force and material of the wall, and is divided into solid wall, sintered hollow brick wall, hollow bucket wall and composite wall according to the wall structure.

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. At the same time, there are 4 bricks long, 8 bricks wide, and 16 bricks thick in 1m masonry, so that the amount of bricks used in 1m masonry is 4 8 16 = 512 pieces, and the amount of mortar is used.

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

Generally, the thickness of the northern house will be used is a frame structure of 24 walls, the exterior wall of the brick-concrete structure is 37 walls, and only the mezzanine of individual houses to insulate the air has 65 walls. The common bathroom wall with sliding door has 12 walls or 18 walls, in fact, the most common ones are 120 and 220 and 240 thick walls.

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 brick form a relationship between length, width and thickness 1 2 4. At the same time, there are 4 brick lengths, 8 brick widths, and 16 brick thicknesses in 1m-long masonry, so that the amount of bricks used in 1m3 masonry is 4 8 16 512 pieces, and the amount of mortar is used. The current wall thickness is determined by the length of the brick, and the following are commonly used:

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

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

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

2. Brick wall: the drawing is marked as 490mm, and the actual thickness is 490mm; 3 4 brick wall: the drawing is marked as 180mm, and the actual thickness is 180mm.
