Urgent need for the calculation formula of the wall, column, roof, etc. of the foundation in the pro

The general formula for calculating the engineering quantity of concrete strip foundation is:

v=l×s (4-12)

where v is the volume of the strip foundation (m3).

l - strip foundation length (m), the outer wall is calculated according to the length of the center line, and the inner wall is calculated according to the net length of the foundation.

s - strip foundation section area (m2).

If the interior and exterior walls have a beam-type ribbon foundation, the T-joint part of its junction (the volume of the figure is calculated as follows:

v = v1+v2

v1=l with b h1

v2= l h2 (2b+b) 6 (4-13).

In the formula, V lap - T-joint lap volume (m3).

v1 - (b) The lap volume of the H1 section in the figure (m3).

v2 - (b) The lap volume of the H2 section in the figure (m3).

If the interior and exterior walls are beamless belt foundations, v build = v2.

Cast-in-place columns are reinforced concrete columns that are on-site formwork and poured in situ, such as frame columns and structural columns. The engineering quantity is calculated in cubic meters according to the cross-sectional size multiplied by the column height shown in the figure.

Column sections are calculated according to the plane geometry of the size shown, and the common geometric sections are rectangular, circular, circular (hollow column) and I-shaped.

Wherein, because the cross-sectional area of the structural column is calculated by the formula.

Structural column cross-sectional area = d1d2+ (4-14).

where d1 and d2 are the dimensions of the two directions of the structural column.

n1, n2 - the number of edges snapped in the direction of d1 and d2.

The height of the column shall be determined according to the following provisions:

Cast-in-place concrete beams.

Cast-in-place beams include foundation beams, general beams and ring beams. The engineering quantity is calculated by multiplying the section size shown in the figure by the beam length in cubic meters.

The length of the beam shall be determined according to the following provisions:

When the beam is handed over to the column, the beam length should be calculated according to the net distance between the columns;

When the main beam is connected with the secondary beam, the length of the secondary beam is calculated to the side of the main beam. The volume of the beam head and beam pad extending into the wall is combined into the beam volume for calculation.

In short, the length of a beam with a small cross-section is calculated to the side of a beam with a large cross-section.

5) Cast-in-place concrete slab.

The structural form of cast-in-place concrete slab can be divided into beam slab, beamless slab, slab, arch slab, etc. The engineering quantity is calculated by multiplying the area shown in the figure by the plate thickness in cubic meters.

Cast-in-place slabsBeamed plate refers to a plate with beams, and the engineering quantity is calculated according to the sum of the volumes of beams and plates.

The beamless plate refers to the plate without beams and directly supported by the column head, and its volume is calculated according to the sum of the volume of the plate and the column cap.

Slab refers to a slab without columns and beams, and is directly rested on the load-bearing wall on all sides, and its engineering quantity is calculated according to the solid volume of the slab. When there are multiple types of plate connections, they should be divided by the center line of the wall, and the plate head protruding into the wall should be merged into the plate for calculation.

When the cast-in-place eaves gutter is connected with the slab (including the roof panel and the floor slab), the outer wall is the dividing line, and when it is connected with the ring beam (including other beams), the outer edge line of the beam is the dividing line. Outside the edge of the exterior wall or outside the outer edge of the beam is the eaves gutter.

If the concrete slab is poured composite high-strength thin hollow pipe, the engineering quantity should be deducted from the volume occupied by the pipe, and the composite high-strength thin hollow pipe should be included in the **. Lightweight materials are used to pour in the beamed slabs, and the lightweight materials should be included in the **.
