Improved method for stability of wheeled scaffolding plugs

Jul 11, 2019

The wheel-type scaffolding is a kind of in-line type new steel pipe scaffold with self-locking function. The wheel-type scaffolding has the advantages of simple structure and convenient erection, and is more and more recognized by the construction unit, and it is only used in bridges, etc. The use in very large projects has now gradually applied to other general constructions.


The wheeled scaffold is mainly composed of structural components such as a pole and a crossbar. The disc on the pole and the plug on the crossbar are connected as structural connectors, so the disc and the plug become the stability in the whole system. The most important link.


The structure of the initial plug was in the form of a cross-section that was inserted into the disc by a certain taper. After a period of construction application, we found that due to the narrow lateral area of the plug, the contact area with the pole after insertion of the plug is small, such a structure is easy because the plug is not completely aligned during the processing, or during the construction process. Standard operation, resulting in the plug can not completely fall into the disc, can not completely lock and other phenomena, bringing safety hazards to the entire structural system.


The plug structure of the scaffold is improved, a lateral semi-circular arc guide rib is added on the upper edge of the plug, and the contact surface with the pole is enlarged, and the crossbar and the pole are completely covered, thereby effectively improving the system. Stability, even in the case of less standard operation, also compensates for other problems due to the advantages of structural design, greatly reducing some security
