Accurate calculation of beam height
Besides the height perpendicular to the beam axis, the angle between the longitudinal axis and the vertical should be considered, and the actual beam height should be calculated by XCOS function. For other calculations of the same beam volume, the length of the beam is subject to the length of the center line, and there is no need to deduct the rotation angle.
Calculation of plate thickness
The calculation of plate thickness is also an important part of template engineering quantity calculation, don't forget.
Calculation of formwork height
If the formwork height of cast-in-place reinforced concrete columns, beams, slabs and walls is less than 3.6 meters, the additional supporting quantities shall be calculated separately for the excess part.
Calculation of holes
For formwork engineering of walls and slabs, if the area of a single hole is less than 0.3 square meters, we will not deduct this hole, and the side wall formwork will not be increased; However, if the area of a single hole exceeds 0.3 square meters, the hole will be deducted, and the formwork area of the side wall of the hole will be added to the calculation of formwork quantities of walls and slabs.
Calculation of anchorage length of steel bar
When the nominal diameter of ribbed bar exceeds 25mm, the anchorage length shall be multiplied by the correction factor 1. 15. In the earthquake area, the corresponding coefficient should be multiplied by the seismic grade:1.15 for the first and second grades; Level 31.05; 1.0 level 4. In addition, if the longitudinal compressive reinforcement in concrete is fully utilized, the anchorage length should not be less than 70% of the corresponding tensile anchorage length.
Description part of construction drawing design
The design description part of the construction drawing usually has clear requirements for the anchorage length of steel bars. Please remember to check before construction!
