So, what are the shortcomings of the frame scaffold compared to the trapezoidal scaffolding? Here I simply for you to tell a few points.
1, frame scaffolding need to be fastened by a small part to complete the lap, and fasteners easy to manage is easy to lose;
2, the frame scaffolding can not guarantee the support of the force does not deviate from the center, and rely on the fastener to make the load to reduce;
3, frame scaffolding fasteners as most of the casting parts, easy to damage, especially the quality of the key to the rental more difficult to guarantee, so that the construction safety buried hidden;
4, scaffolding in the construction of the inevitable bump, fall will make the fastener break can no longer use, so that the construction costs inadvertently increase a lot;
5, frame scaffolding node fastener connection mainly rely on the experience of workers with the feeling of hinge, too loose easy to buckle, too tight easy to collapse, so tight is difficult to grasp;
6, frame scaffolding installation lap slow, time-consuming, regardless of the installation and lap need to workers one nut screw, not only increase the working hours and large amount of work.
