Whether the interior wall plastering height is based on the building elevation or the structural ele

In general, the building elevation is calculated, if it is a project imported from the steel bar GGJ2009, when the elevation is set according to the structural elevation, the bottom elevation of the first layer of exterior wall plastering can be adjusted according to the design outdoor floor elevation, and the elevation of the rest of the floors does not need to be adjusted.

Wall plastering refers to the surface layer of cement mortar, mixed mortar and white mortar plastered on the wall.

1.The following preparations should be made before the large stucco (main body acceptance):

1) Make ash cake: According to the surface of the base level, vertical situation, hang the vertical line, pull the wall surface of the long line, must be square yin and yang corners, after inspection to determine the thickness of the plaster, but the thinnest point should not be less than 7mm, the thickest part is not more than 20mm. Ash cake should be used 1:

3. The cement mortar is made into a 3cm square shape. When making ash cakes, make a ash cake at 30cm under the flat roof and on the floor along the height range, and make another ash cake in the middle;

2) Corner protection: The sunny corners of walls, columns and door openings should be leveled with 1:2 cement mortar and ash cake, and then wiped into small corners 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.

3) The oil stain and paint on the surface of the concrete should be brushed with a wire brush before plastering, and the surface of the concrete should be brushed with an interface agent, and the screw hole on the external wall must be embedded with cement mortar.

2.Before painting, the brick wall should be watered thoroughly overnight, and the wall should be watered and moistened from top to bottom with a thin pipe.

3.The cast-in-place board is cut straight 20cm upwards when painting, and the baseboard is darkened with 1:3 cement mortar powder after the floor is ready.

4.Plastering bottom ash: the thickness of the bottom ash is lower than the ash cake 6 8mm, first plastered with a thin layer to make it solid with the wall, then layered plastering, and then with a large scraper ruler in the horizontal direction from top to bottom slowly scraped, and finally with a broom to sweep the hair.

5.Plastering surface layer mortar: The surface layer mortar is painted 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, verticality, squareness and straightness of the wall and the square and straight angles of yin and yang, and whether there is a deviation at the intersection of the beam and the column.

If there is any deviation, it should be repaired in time until it is qualified.

The elevation before no plastering is the structural surface height, and the elevation after plastering is the building elevation.

Structure. Above the wall skirt to the bottom of the board, the baseboard is not buckled.

The side walls of the subtracted openings are not increased.

The amount of plastering work on the interior wall is calculated in m2 according to the plastering area of the structural dimensions shown in the interior wall diagram. The plastering length of the interior wall and the interior wall skirt is calculated by the length of the structure between the walls, and the height of the interior wall plastering height is calculated according to the height of the indoor ground or floor to the bottom of the ceiling when there is no wall skirt; When there is a wall skirt, its height is calculated according to the height from the top surface of the wall skirt to the bottom surface of the ceiling; When there is a nail board ceiling, it is calculated according to the indoor ground or floor to the bottom surface of the ceiling. The height of the interior wall skirt is calculated from the interior floor or floor to the top surface of the wall skirt.

The plastering area of the inner wall and the inner wall skirt should be deducted from the area occupied by the door and window openings (the outer area of the door and window frame) and the empty ring, and the area of the baseboard, hanging mirror line, the inner hole and the junction between the wall and the component should not be deducted, and the side wall and top surface of the hole should not be increased. The area of the wall buttress and the side wall of the chimney attached to the wall should be incorporated into the corresponding wall plastering quantity.

In the calculation of interior wall plastering, the height of the interior wall is calculated to the bottom of the ceiling according to the indoor floor (ground), and the floor is the structural elevation?

In the calculation of interior wall plastering, the height of the interior wall is calculated according to the indoor floor (ground) to the bottom of the Zhengzi ceiling, is the floor floor a structural elevation? Kiss! Hello, happy to answer your <>

The pro-building ground is the building elevation, not the structural elevation, the building elevation floor top elevation, and the structural elevation is the top elevation of the reinforced concrete floor slab. The floor is a concrete floor slab plus a surface layer, and the surface layer is generally 30 or 50 thick, that is, the building elevation is 30 or 50 higher than the structural elevation (the same layer is carefully measured). Extended Material: I hope my Broad Bush Forest can help you <>

Do you have any other questions?

The height of interior wall plastering shall be calculated according to the following provisions:

For those without wall skirts, the height is calculated from the indoor floor or floor;

If there is a wall skirt, the height is calculated from the top surface of the wall skirt;

If there is no ceiling, the height is calculated to the bottom surface of the floor;

If there is a ceiling, the height is calculated to the bottom surface of the ceiling ceiling and an additional 100mm.

The amount of plastering work on the interior wall shall be calculated according to the plastering length multiplied by the height of "m2", and the area occupied by the openings and empty circles of doors and windows shall be deducted, and the area of the baseboard, hanging mirror line, the inner hole and the junction between the wall and the component shall not be deducted; The side walls and top surface of the cave are not increased; However, the plastering of the side walls of the wall buttresses and the side walls of the chimneys attached to the wall should be combined with the amount of interior wall plastering.

The plastering of reinforced concrete beams and columns in the wall shall be calculated in the corresponding wall plastering quantity.

The length of the plastering of the interior wall is calculated based on the net length of the main wall as illustrated between the main walls.

This is to distinguish whether there is a wall at the bottom of the beam, if there is no wall, the side plastering of the beam is counted as a plate;

If there is a wall at the bottom of the beam, the side plastering of the beam counts as the wall.

The beam surface is counted as a ceiling project! If it is a repair of quality problems, it does not need to be calculated, and it can be priced if there is a visa form!

Confused. Solving.

I know that the interior wall plastering has a suspended ceiling and does not wipe to the top, and the height is calculated to the bottom surface of the ceiling plus 15cm. . .

Is there a design code for the thickness of the plastering of the exterior walls of the building (especially the high-rises) that regulates its thickness?

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.

The plastering height of the wall and column is according to the building elevation.

The decoration of the wall, column plastering height and ground is done in accordance with the architectural drawing, which means that the architectural drawing only wants the final result and effect. The structural drawing mainly shows the stress level of the structure, and the building elevation will be subtracted from the structural elevation marked by the building practice according to the architectural drawing. It is said that the architectural drawings are also in front.

Therefore, your plastering height should still be controlled according to the building elevation, or you will finally make the ground decoration, and your plastering height will still be a few centimeters lower.

If you don't have the height of the floor practice, you can go to the building drawing to find the atlas selected for the floor practice and calculate the height of the floor practice yourself. It is not necessary to directly determine the plastering height according to the control elevation and building elevation.

The room should be decorated with interior walls first, then the ceiling, and then the floor. The plastering height of the wall and column is according to the building elevation.

The plastering height is the clear height of the building, that is, the height from the bottom of the roof to the ground of the building.
