What is the standard for plastering thickness of brick walls?

According to the surface of the base level, vertical situation, hang the vertical line, pull the wall surface of the long line, mustYin and Yang CornerFangzheng, after inspection to determine the thickness of the plaster, but the thinnest point should not be less than 7mm, the thickest part should not exceed 20mm.

Ash cake. It is advisable to use 1:3 cement mortar.

Make it into a 3cm square shape. When making ash cakes, make a ash cake under the flat roof and 30cm above the floor along the height range, and make another ash cake in the middle.

Corner protection: The yang corner of the wall, column and door opening, 1:2 cement mortar should be used to level the base and ash cake, and then wipe it into a small corner after the mortar is slightly dry. The width of each side should not be greater than 5cm. All corners must be square and straight. The size of the door opening is uniform, and each side is reduced by 15mm.

Plastering the surface layer of mortar.

The surface layer of mortar is flat with the ash cake, and the sand rate should not be too coarse. The bottom ash must be painted overnight, the next day the surface layer of mortar, scraped straight with a scraper and then flattened with a wooden crab, and then calendered horizontally with an iron plaster, and the yin corner is pumped with an angle iron.

The texture of the iron trowel should be straightened out left and right, and there should be no messy iron plate lines, so that the entire wall surface is smooth and smooth, and the fine lines are consistent. Then, the wall is tracked and inspected with a detection ruler, mainly to check the flatness and verticality of the wall.

The square and straight angles of yin and yang, and whether the intersection of beams and columns is deviated. If there is any deviation, it should be repaired in time until it is qualified.

Standard brick net consumption = 2 masonry thickness number of bricks {masonry thickness (standard brick length + ash joint thickness) (standard brick thickness + ash joint thickness)}

A brick wall is thick, and the ash joints are taken.

Bringing in the formula, it can be calculated that the net amount of bricks is:

529 blocks. Net amount of mortar = 1 - number of bricks Brick volume.

Net mortar consumption = 1-529 * cubic meters.

Generally, the thickness of brick wall plastering is about 8 to 10mm, if the brick wall is uneven, it is recommended to level and then plaster. Or rub it thicker.

Dear, I am glad to answer for you: the bottom ash should be at least 2 cm, otherwise it will affect the quality of tile bonding, if the flatness of the base is not high, then the thickness needs to be controlled at 3 to 4 cm, so that the digging can avoid the completion of the tile paving, there is a height difference. Under normal circumstances, the thickness between the ground and the finished surface is 5 cm, that is, the thickness of the yellow bent bright sand cement is about 3 4 cm.

Of course, the thickness of 2 cm of the sand and ash layer can be buried wide and paved with floor tiles, but it only adds some difficulty.

Hello! If the thickness of the plastering layer is too large, it will not only waste material resources and manpower, but also affect the quality. If the plastering layer is too thick, it is easy to crack and warp the plastering layer, which will cause the plastering layer to fall off and cause safety accidents.

Therefore, the plastering layer is not the thicker the better, as long as it meets the provisions of the quality evaluation standard, such as the top plastering thickness of 15 20 mm, the interior wall plastering thickness of 18 20 mm and so on.

Ordinary exterior wall plastering is divided into three layers, the bottom layer, the middle layer, and the surface layer. The total thickness of the three layers is 15-20mm, and the maximum thickness is not more than 25mm. Generally, the bottom layer is about 5mm, the middle layer is about 5-12mm, and the surface layer is 2-5mm.

Preparation before plastering the wall:

1. Make ash cake: make the gray cake on the exterior wall twice, the first time the ash cake is flat with the rough surface, and the thickness is not less than 7mm at the thinnest point. The bay window sill and the side panel ash cake followed at the same time.

2. After the acceptance of the main body, start to paint a layer of concrete interface agent on the surface of the concrete beam and column.

3. The screw hole of the exterior wall must be plugged with construction paste and closed with cement mortar.

Extended Materials. Problems that need to be paid attention to when plastering walls:

1. Poor bonding, hollowing, cracks.

The bond between the stucco layer and the substrate is not firm, hollow, and cracked. The main reason is that the base is not clean, washed with water, not wet enough, and the surface of the concrete is not coated with interface agent. Due to the strength growth and hardening process of the mortar, it produces uneven shrinkage stress and forms dry shrinkage cracks.

Cracks, frosting, and peeling of cement mortar walls.

2. The plastering layer is too thick.

The thickness of the plastering layer greatly exceeds the regulations, especially if it is a single success, which will crack the plastering layer. The thickness of the plastering layer should be controlled by punching bars, and it is advisable to keep it at 20mm. During the operation, it should be layered and intermittently plastered, and the second time should be wiped after the first time the ash is finally set, and it should not be survived once.

3. The side seams of the door and window frames are not stuffed with ash or the ash is not solid.

Hollowing and cracks on both sides of the window frame, the door and window joints should be regarded as a process by a special person, and the side joints of the door and window frame must be filled with cement mortar or fine stone concrete after the foaming agent is laid to prevent cracking and water seepage.

4. Different varieties of mortar should be used for wall painting.

Different varieties of mortar shall not be mixed, mortar should be mixed with use, it is strictly forbidden to use overnight mortar, and the ground ash should be cleaned at any time during operation.

Generally around one centimeter.

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.

What is the general thickness of exterior wall plastering? What are the requirements for the thickness of exterior wall plastering? The following is an introduction to the main content of the specification requirements for exterior wall plastering thickness brought by Zhongda Consulting for reference.

In accordance with the provisions of the Code for Construction and Acceptance of Building Decoration Engineering, the average total thickness of the plastering layer shall not be greater than the following provisions:

1 Ceiling: slats, hollow bricks, cast-in-place concrete - 15 mm; Precast concrete – 18mm; Metal mesh – 20mm.

2. Interior wall: ordinary plastering - 18mm; Intermediate plastering - 20mm; Premium plastering – 25mm.

3 Exterior wall - 20mm; Leg and protruding wall part - 25mm.

4 Stone wall – 35mm.

The purpose of controlling the average total thickness of the plastering layer is mainly to prevent the plastering layer from falling off.

Ceiling plastering, the plastering layer relies on the adhesion of the plastering mortar (or mortar) and the ceiling surface, so that the plastering layer can stick to the roof surface, when the plastering layer is too thick, the self-weight of the plastering layer exceeds the adhesion force, the plastering layer will automatically fall down. And because the size of the adhesion is related to the smoothness of the roof surface, the smoother the roof surface, the smaller the adhesion force. Therefore, the control thickness of the plastering layer of slats, hollow bricks and cast-in-place concrete roof surfaces is smaller than that of precast concrete roof surfaces.

If there is a metal mesh on the ceiling surface, the thickness of the plastering layer on the metal mesh can be larger because the mortar can be embedded in the grid, which increases the tie force.

Wall plastering, the plastering layer relies on the adhesion between the plastering mortar and the wall and the friction between the plastering layer and the wall, so that the plastering layer can stick to the wall. When the thickness of the plastering layer is too thick, and the weight of the plastering layer exceeds the sum of friction and adhesion, the plastering layer will fall off. And because the adhesion and friction are related to the degree of wall smoothness, the rougher the wall, the greater the adhesion and friction, therefore, the thickness of the stone wall plastering layer is larger than that of the brick wall.

The thickness of the interior wall plastering layer should be determined according to the plastering grade, and the thickness of the advanced plastering control is larger than that of ordinary plastering, which is due to the fact that the surface flatness of the advanced plastering is higher than that of ordinary plastering, that is, the allowable deviation of surface smoothness is smaller, and the surface flatness of the plastering layer is adjusted by the thickness of the mortar layer, and the higher the surface flatness, the more generous the thickness of the mortar layer used to adjust.

Summary. The average thickness of ordinary ash should not be greater than 20mm, and the average thickness of advanced ash should not be greater than 25mm.

The average thickness of ordinary ash should not be greater than 20mm, and the average thickness of advanced ash should not be greater than 25mm.

The average thickness of the autoclaved aerated concrete block base should be controlled within 15mm, when the polymer cement mortar is used to make the ash, the average thickness should be controlled within 5mm, and the average thickness should be controlled within 5mm when the gypsum mortar is used. When the thickness of the trillion section of ash is greater than 35, it is necessary to adopt strengthening measures (such as steel wire mesh, steel mesh, etc.).

1. The strength of wall plastering is generally m6. Interior wall plastering mortar is generally mixed mortar in a ratio of 1:1:

4 (cement: lime paste: yellow sand), which is commonly known as 114 mortar.

2. Classification according to the position and direction of the wall in the building: it is divided into two categories: exterior wall and interior wall. The walls arranged along the perimeter edge of the building are called exterior walls, and the walls that are surrounded by external walls are called interior walls.

The outer wall is an outdoor air partition wall, and the outdoor air is directly connected to the wall of pure contact of macro pants, which is mostly a "cold wall". Interior walls refer to walls that play the role of separating spaces indoors and are not in direct contact with outdoor air, and are mostly "warm walls". High-rise decoration indoor shelter has a wall, in this case to batch putty if you want to wait a few more days, after all, it is indoors to live indoors, and too anxious to be easy to cocoon in the later stage.

What should be the size of the plastering that needs to be tiled?

The number of cement mortar is generally m5 m10 m15, etc., 1:2 general use grade or cement, cement varieties are generally divided into Portland cement, ordinary Portland cement and slag, pozzolana ash, fly ash Portland cement. The latter three types of cement are generally used for plastering, because the cost of the first two types of cement is much higher than that of the latter three types of cement.

According to the situation of the underground chain excavation area in different places, the cement used is also different.

The plastering mortar is marked with a strength of 1:4 cement mortar of about 10MPa, which is equivalent to the strength of M10 mortar, but note that 1:4 is not a mass ratio, but a volume ratio of raw materials.

1:1:4 mixed mortar refers to cement, bent lime and sand with a weight ridge ratio of 1:

1:4.The mixed mortar is generally made of cement, lime plaster, and sand, and is generally used for masonry above the ground celery. Mix.
