The supporting height of formwork column shall be calculated separately: 1. When formwork column is supported on the top surface of pile cap or foundation beam, it shall be calculated from the top surface of pile cap and foundation beam to the bottom of beam or plate, and the dimensions of formwork and square timber shall be deducted.
For the length of the ground beam, you'd better see what quota you want to set and calculate it according to the quota calculation rules, because different quota calculation rules will be different. Generally speaking, for ground beams, it is the net spacing of columns or the net spacing of foundations multiplied by the cross-sectional area in cubic meters. It is best to look at the corresponding quota calculation rules.
Subtract the height of the beam according to the height of the finished surface of the structural layer, which is the height of the beam bottom. What we usually see is that the beam supported by woodworking formwork is not the actual height of the beam, but the actual height of the beam after concrete pouring is dense.
1 is the arctangent value. 2m & #47. 1 Then click SHIFT and then click tan, which is the arctangent, that is, the inverse trigonometric function of tan. You find a scientific calculator and enter 0. 1 = Tan5.7 1.
So the slope of this beam is 5, the ridge height is 1, and the arc tangent is 0. 1 is 0; 24 meters spent half, evil spear 12 meters =0. The rectangular truss with 10# channel steel and angle steel as web members in the middle can meet the requirement of 600mm height.
