In interior design, what is the thickness of the external wall, internal wall and masonry wall of the house?

1, the outer wall is about 24 cm, and the inner wall is about 15 cm.

2. The size of standard clay brick in China is 240× 1 15×53mm, and the purpose of this size is to ensure that the ratio of length to width of brick is 4:2: 1 (including the width of mortar joint 10mm). The thickness of a brick wall is usually called the multiple of the brick. Because the length of a brick is 240mm, a brick-thick wall is also called "24" wall, a half-brick-thick wall is also called "37" wall, and a half-brick-thick wall is also called "12" wall.

3. According to the position of the wall in the building, it can be divided into external wall and internal wall, and the internal wall separating the room is also called partition wall. The external walls located on both sides of the house are called end walls or gables; The outer wall above the roof is called a parapet. According to the stress of the wall in the building, it can be divided into load-bearing wall and non-load-bearing wall. Shear wall is a load-bearing wall for buildings to resist horizontal forces.

Extended data

Modern large-scale masonry is produced in one block, so the grouting work of mortar joint is not considered. If the mortar joint is grouted, the so-called "mortar skateboard" can be used, which can not only save labor time, but also make the mortar joint uniform.

In order to make the masonry meet the planning requirements, the masonry cutting machine is essential. Through it, masonry composed of lightweight concrete, porous concrete or porous brick can be cut very accurately. In addition, about 10 supports are needed, and at least 10 2.5~3m long boards and 1 ladder are needed.

In order to make the vertical pressure and horizontal thrust between bricks in the wall evenly and reasonably distributed, the principle of "staggered joints and overlapping" must be followed in the process of bricklaying, that is, the vertical joints of upper and lower bricks in the wall are staggered regularly, thus ensuring the strength and stability of the wall.
