What does each of the 2 3 8 1 in the 2381 bricklaying method represent

2381 masonry method (i.e., two kinds of footwork, three kinds of body methods, eight kinds of plastering techniques, one squeezing action).

At the inaugural meeting and the first annual meeting of the China Engineering Construction Quality Management Association, the 2381 bricklaying method of the 2381 bricklaying method was proposed to realize the ———standardization of bricklaying projects, which aroused strong responses from the participants. After that, the Ministry of Construction and the State Science and Technology Commission Achievement Department organized a nationwide promotion activity, and the top spears became the top local bricklayers in the construction youth technology competition in various regions. In the 1990 National Youth Technology Competition, there were 3 2381 bricklayers who entered the top ten bricklayer technical experts, all of whom were beginners in bricklayer technology and had worked for about 3 years.

Today, most of these 2,381 bricklayers have become the backbone of the local construction industry, and some have gone to school and held leadership positions. The training work has entered the whole system training of the construction labor base, and the effect is particularly prominent. In 1990, the training of Luzhou and Suining labor bases in Sichuan Province showed that the young people trained had a certain level of cultural knowledge, and had the characteristics of being good at thinking, having the courage to forge ahead, having a strong desire for knowledge, and being able to bear hardships and stand hard work.

The training work is progressing smoothly, in the single bricklaying action large exercise day practice 5000 times intensive training without any lagging behind, after 20 days of training can master the basic skills of 2381 bricklaying, in the actual engineering practice for 2 months, that is, to become a skilled bricklayer. It is confirmed that the 2381 bricklaying method is "easy to learn, easy to get started, and not easy to climb." "If you want to really learn 2381, you can only study hard, so as to realize the original intention of the inventor to study bricklaying technology.

The thickness of the solid standard wall is 240mm, 370mm, 490mm, 620mm and 740mm.

Sometimes, in order to save materials, the wall thickness can be counted as 1 4 bricks instead of half a brick, so some bricks need to be side-built to form a wall thickness of 180m, 300mm, and 420mm.

The abbreviation of the wall thickness of 2 3 8 1 you said, which means the wall thickness: 240mm, 370mm, 180m, 120mm (for the indoor non-load-bearing wall).

What do you mean? Is it the masonry of the two-four walls and the eight-eight walls?

Bricklaying 4,2,1 is a construction technique that refers to arranging bricks together in a 4:2:1 ratio to enhance the stability and strength of a building.

This technique can be used to construct walls, columns, stairs, etc., and can also be used to repair broken parts of buildings.

The 4:2:1 ratio refers to the horizontal arrangement of bricks with four bricks in each row, two bricks in every two rows, and one brick in every three rows. This technology can make buildings stronger, resistant to the impact of external forces, and also resistant to devastating climate change.

In addition, bricklaying 4:2:1 can also be used to enhance the aesthetics of a building, such as adding decorative bricks to the walls to change the appearance of the building.

In conclusion, bricklaying 4:2:1 is a very useful building technique, which can improve the stability and strength of the building, as well as increase the aesthetics of the building.

Bricklaying 4,2,1 is a bricklaying technique that refers to putting four bricks together, then putting two bricks on the other side, and finally putting one brick in the middle. This technique allows the bricks to be more tightly grouped, which improves the strength and durability of the brickwork. In addition, bricklaying 4,2,1 technology can also reduce the gaps in bricklaying, thus preventing water penetration and making the building stronger and more durable.

Therefore, the bricklaying 4,2,1 technique is a very practical bricklaying technique that can improve the strength and durability of buildings.

Hello, bricklaying 421 means a bricklaying technique, also known as "horizontal bricklaying", which refers to placing the bricks horizontally, the length of each row of bricks is 4 bricks, the height of each row of bricks is 2 bricks, and the length of the last row of bricks is 1 brick. This bricklaying technology can make the masonry more stable and stronger, and it can also save more masonry and more cost-saving.

Bricklaying 4,2,1 refers to the bricks in the order of 4 layers, 2 layers, and 1 layer.

Bricklaying 421 refers to a construction technique, that is, four independent bricks are built into a square spiral brick in proportion, and then glued with mortar. This technique is very commonly used, and its advantage is that it can ensure the strength of the bricks, and at the same time ensure that the spacing between the brick joints is smaller, so as to improve the overall aesthetics on the basis of ensuring the strength of the structure.

Bricklaying 421 is a construction technique that refers to the bricks being put together according to certain rules to form a solid structure. The technology of bricklaying 421 is very complex, and it is necessary to grasp the size, angle and structure of the bricks, as well as the degree of joints between the bricks.

The 2381 operation method is to summarize the action process of bricklaying bricks into two kinds of footwork, three bending postures, eight kinds of plastering techniques, and a kind of squeezing action, which is called 2381 bricklaying action specification, referred to as 2381 operation method.

When squeezing, brick should fall at the length or width of ash strip 2 3, and that part of mortar that exceeds the thickness of ash joint is squeezed into vertical joint. If the ash is too thick, too much mortar can be extruded by kneading.

When squeezing and kneading, it is necessary to throw the remaining slurry into the vertical joint, and if the vertical joint is full of slurry, it can also be thrown back into the ash hopper in real time.

The masonry methods of brick masonry include "three-one" brick-laying method, "two-three-eighty-one" bricklaying method, squeezing method, scraping method and full ash method. Among them, the "Sany" bricklaying method and the squeezing method are the most commonly used.

2381 "bricklaying method: that is, by two kinds of footwork (T-step and parallel step), three body methods (T-step and parallel step of the side bend, T-step is bending and parallel step is bending), eight kinds of ash laying techniques (brick-laying with throwing, buckle, splash, slip and brick-laying buckle, slip, splash, with two) and a kind of squeezing action (when laying bricks with fingers, so that the bricks falling on the ash groove produce a slight tremor, the mortar is liquefied after vibration, and the cement slurry particles in the mortar fully enter the surface of the brick, produce good adsorption and bonding) is composed of a set of advanced bricklaying technology that conforms to the normal activity of the human body.

2381 "bricklaying method has the following characteristics:

The use of this method can better ensure the quality of masonry, it is based on the "Sany" bricklaying method, and the action is coherent and uninterrupted, to avoid the long time of plastering and affect the bonding strength of the mortar.

In the process of operation, the footwork, body method and technique have been optimized, and the actions that should be done on different operating surfaces and operating positions such as far, near, high and low are clearly stipulated, so as to eliminate redundant actions and improve the masonry speed.

Using this method, the layout of the on-site operation plane and the stacking of materials can achieve reasonable layout, standardized operation and civilized construction.

In line with the physiological and operational characteristics of the human body, it can greatly reduce the fatigue intensity of the operator, and has a certain positive effect on the prevention and elimination of workers' occupational lumbar muscle strain.

The operation method is simple and easy to learn, and generally a new worker can master the essentials after two or three months of intensive training.

What is the 2381 operation method?

Answer: The 2381 operation method is to summarize the action process of bricklaying bricks into two kinds of footwork, three bending postures, eight kinds of plastering techniques, and a kind of squeezing action, which is called 2381 bricklaying action.

Specification, referred to as the 2381 operation method.
