What is the reference standard for hanging basket preloading
For example, the bridge is a linear change in the loading process, the difference between the maximum and the minimum is only 2 mm. The average deflection is 12 mm. It provides a reliable basis for setting the elevation of the vertical die by preloading
Before 5.1. preloading, it is necessary to fasten the tension rod of the anchor system, especially the pull rod of the back pressure system and the front cross beam system, so that the tension force can be even.5.2. preloading, with 10 tons for a level two basket symmetrical at the same time, a total of 100 tons of load on each side, each load time must be very carefully observe the guide beam elevation, and paying close attention to the hanging basket system whether there is a significant change
It is necessary to attach great importance to the pre pressure, which is an important prerequisite for the implementation of safety management. The biggest hidden trouble of hanging basket construction is the collapse of the collapse, resulting in equipment damage, casualties of major malignant accidents. Therefore, preloading is one of the important contents of the safety management of hanging basket construction. How to implement safety pre pressure?
