July 29(th)

Today is still cloudy. The steel bars in Building 6 have been tied. I didn't see the right one last time, but I can see the left one this time.

First of all, scaffolding with a certain height should be set up to support the inclined beam in the stands. In order to fix the inclined beam in a proper position, small bars should be set at different heights along the scaffold. First, put the two ends of the upper reinforced bar of the erection stud on the two ends of the beam, and then put the stirrup on the lower reinforced bar. The part of the steel bar that sinks due to its own weight in the length direction should be cut off with a crossbar, and the upper steel bar should be placed on the scaffold. This can resist the deflection caused by self-weight. The lower steel bars and waist bars are fixed in the proper position of stirrups with iron wires. At the same time, before and after binding, battens are placed under the lower reinforcement, which is convenient for the lower reinforced bar to be bound at the appropriate position of stirrup, and the battens should be removed after binding.
