The brick columns embedded in empty bucket walls shall be calculated separately and the corresponding comprehensive base price of brick columns shall be implemented.

Mixed water wall refers to two walls All brick walls to be plastered during the construction of decoration works.

Other walls that implement the comprehensive base price of clean and mixed water brick walls (1) the quantities of brick partition walls between frame structures are calculated according to the clean and mixed water and different thicknesses, and the corresponding comprehensive base price of clean and mixed water walls is implemented by multiplying the clearance area between frames by the wall thickness.

For the double-sided clean water wall, the corresponding quota sub item of the single-sided clean water wall shall be multiplied manually by the coefficient of 1.05.

Different materials are used for the foundation and wall body.

The brick inlaid part on the outer surface of the frame is included in the quantities of walls between frames.

II.

According to the stress situation, it can be divided into load-bearing wall and non load-bearing wall (partition wall) 3.

When it is located within ± 300mm of the designed indoor floor, it shall be bounded by different materials.

Masonry bricks are also divided into solid bricks and hollow bricks.

2.

Empty bucket wall is a wall built by combining standard machine brick with side brick.

(1) calculated according to the size and volume shown in the design drawing, v = wall length × Wall height × Wall thickness – part of the volume should be deducted + part of the volume should be increased (2) the length of the inner wall is calculated according to the length of the net length line.

empty bucket wall 1.

According to the plane position of the wall, it can be divided into external wall and internal wall.

1.

The calculation is as shown in the figure.

Source: copyright of Zhulong forum belongs to the original author.

The work contents are: mortar transportation, brick transportation, wood brick and iron parts placement.

For the brick arc wall, the corresponding quota sub item of the wall enterprise shall be multiplied manually by the coefficient of 1.2.

(flat brick is called “sleeping brick”, along brick is called “along bucket brick”, and side brick is called “Ding head brick”.) According to the different masonry forms of the facade, the empty bucket wall is divided into four types: one sleeping bucket, one sleeping bucket, one sleeping bucket and no sleeping bucket.

If the design has empty flower wall, the empty flower part is calculated in another item, and the comprehensive base price of empty flower wall is implemented.

When the inner wall intersects the L-shaped of the inner wall, the length of both inner walls should be calculated to the center line, as shown in Figure 7-10 (b) As shown in Figure 7-10 (c).

(4) Brick retaining wall with thickness less than two bricks: calculated in “m3” according to the size shown in the figure, and the corresponding quota of clean water and mixed water shall be implemented.

Single-sided clean water wall refers to the brick wall in which one wall is plastered during the construction of decoration works, and the other wall only needs pointing without plastering.

(II) division of brick foundation and brick wall   1.

The quantity calculation and comprehensive base price of the empty bucket wall are set in “m3” according to the overall volume Calculation.

The volume occupied by door and window openings, reinforced concrete lintels and ring beams shall be deducted.

When the inner wall intersects with the inner wall, it is calculated according to the inner wall length of the thicker wall, and the inner wall length of the thinner wall is calculated to the outer edge line of the thicker wall, as shown in Figure 7-10 (c).

The wall between windows, under windowsill, under floor slab and beam The solid masonry under the head shall be calculated separately, and the comprehensive base price of sporadic masonry shall be applied..

Calculation of masonry quantities   1、 Overview masonry is mainly composed of blocks and mortar   (1) Blocks are divided into three categories: bricks, stones and blocks.

4.

Enclosure: height to the upper surface of capping.

According to different decoration methods, it can be divided into clean water wall and mixed water wall.

ridge wall, heating ditch and other brick ditches under the raised wood floor.

If the slab height of the same wall is different, it can be calculated according to the average height Degree calculation.

III.

Inner and outer Gables: calculated according to the average height, as shown in Figure 7-16.

(2) The parapet wall is calculated from the top surface of the external wall to the height shown in the figure, and the wall thickness is calculated in “m3”, and the corresponding comprehensive base price of clean water wall and mixed water wall is implemented.

(4) determination of brick wall thickness (5) contents that should be deducted and not deducted in calculating wall quantities   3.

Solid brick wall (I) brick wall classification 1.

If it exceeds ± 300mm, it shall be bounded by the designed indoor floor.

Parapet: from the upper surface of roof slab to the top surface of parapet (if there is concrete capping, to the lower surface of capping).

Base price of solid brick wall (1) Precautions: the quota is generally set according to the wall decoration and wall thickness.

2.

The division of brick foundation and brick wall (body) is bounded by the designed indoor floor (if there is a basement, it shall be bounded by the indoor design floor of the basement), the following is the foundation, and the above is the wall (column) body.

4.

The brick enclosure shall be bounded by the designed outdoor floor, the following shall be the foundation, and the above shall be the wall body.

The apex of brick wall height shall be calculated according to the following provisions: external wall: inclined (slope) If there is no cornice ceiling on the roof, the height shall be calculated to the bottom of the roof panel, that is, the height shall be calculated to the intersection of the center line of the outer wall and the bottom of the roof panel, as shown in Figure 7-11; if there is a roof truss and there is a ceiling indoors and outdoors, the height shall be calculated to the bottom of the lower chord of the roof truss plus 200mm, as shown in Figure 7-12; if there is no ceiling, the height shall be calculated to the bottom of the lower chord of the roof truss plus 300mm, and if the eaves width exceeds 600mm, it shall be calculated according to the actual masonry height The roof is calculated to the reinforced concrete top slab surface, as shown in Figure 7-13.

Double-sided clean water wall refers to the brick wall in which both walls only need pointing without plastering.

Masonry stones are divided into rubble and stone.

2.

According to different assembly methods, it can be divided into solid wall, empty bucket wall, empty flower wall, infilled wall, etc.
