1.Quantity calculation rules [Note: column caps of horse teeth, corbels, and lifting plates].
2.Related Notes:
1) Column height regulations:
The height of the column with beams and slabs should be calculated from the height between the upper surface of the column base (or the upper surface of the floor slab) and the upper surface of the previous floor slab.
The height of the column without beams should be calculated from the height between the upper surface of the column base (or the upper surface of the floor slab) and the lower surface of the column cap.
Structural columns are calculated by full height.
2) The cross-sectional shapes of special-shaped columns include T-shaped, L-shaped, Z-shaped, cross-shaped, trapezoidal, etc. When the minimum value of the ratio of the height of the cross-sectional section to the thickness of each side of the special-shaped column is greater than 4, the items are no longer listed according to the special-shaped column.
2021 test question] According to the "Code for Quantity Calculation of Housing Construction and Decoration Engineering" (GB50854-2013), the correct calculation of the quantity of concrete columns is ( ).
a.The height of the column with beams and slabs is calculated from the upper surface of the column base to the elevation of the column top.
b.The height of the column without beams is calculated from the upper surface of the column base to the upper surface of the column cap.
c.The height of the frame column, calculated from the upper surface of the base to the height of the top of the column.
d.The part of the structural column embedded in the wall is incorporated into the calculation of the wall quantity.
Correct answer c
Answer analysis This question examines cast-in-place concrete engineering. Option a, the height of the column with beamed slabs, should be calculated from the height between the upper surface of the column base (or the upper surface of the floor slab) and the upper surface of the previous floor slab; Option b, the height of the column without beams, should be calculated from the height between the upper surface of the column base (or the upper surface of the floor slab) and the lower surface of the column cap; The structural column is partially incorporated into the column body volume.
