Specification requirements for masonry walls

The specifications for masonry are:

1. When building a wall, it must be horizontal and vertical to prevent later collapse.

2. When mixing mortar on site, the saturation of the mortar should reach more than 80%.

3. The wall must have staggered joints up and down to ensure the stability of the wall.

4. The height of the connection must ensure safety, and the length cannot be less than 2/3 of the height.

5. When building walls, the thickness of plaster should be controlled between 8 and 12 mm.

6. Construction cannot be carried out on rainy days.

The specific introduction is as follows:

1. Horizontal and vertical lines

When building walls, professional construction workers will remember an important formula, horizontal and vertical lines. Straight, because only by making it horizontally and vertically can the verticality of the wall be ensured, and it will not tilt or collapse later. In order to ensure the verticality of the wall, infrared rays must be used to mark horizontal lines during construction. This will be much more convenient during construction.

2. Mortar saturation

In addition to bricks, mortar is also used when building walls. Mortar is generally processed on site. When mixing mortar, be sure to pay attention to its saturation. Try to achieve a saturation of more than 80% to ensure the solidification of the mortar. If the saturation is relatively low, the wall may crack later, and the wall may be damaged. The gravity is also relatively poor.

3. Staggered joints up and down

In order to make the wall have good stability and bearing capacity, there must be staggered joints up and down, so as to ensure the grip between bricks. There are not many requirements for nailing force and up and down staggered seams, but generally we will ensure that the shape of the up and down staggered seams is particularly similar to the I-shape, because this method of operation is simple and can also ensure the stability of the wall.

4. Safety

One of the most important issues to pay attention to when building a wall is safety, so the connection must be reliable, and the length of the connection cannot be less than 2/2 of the height. 3. If the house is built in an earthquake-prone area, remember to add tie bars. It is best to construct tie bars along the wall, leaving at least two tie bars on each floor.

5. Plastering thickness

When plastering, the thickness of plastering should be controlled at about 8 mm to 12 mm. If the thickness of plastering exceeds 12 mm, then It may cause the wall to tilt. If the thickness of the plaster is less than 8 mm, the stability of the wall will be relatively poor, so the thickness of the plaster must be controlled well.

6. Construction Weather

Be sure to check the weather conditions on the second day or the next week before construction, because there are also weather requirements for cutting off walls, such as It is said that construction cannot be carried out on heavy rain days. If the rain outside is not very heavy and you want to seize the time for construction, then the height of the wall built every day cannot exceed 1.2 meters.
