​How much weight can a scaffold coupler hold?

Scaffolding can be convenient for high-rise construction, but also can be used for the transfer, transportation, temporary stacking of construction materials, which requires scaffolding to have a certain bearing capacity. A scaffold coupler is an important fastener used to connect and fix the scaffold pipe when building the scaffold. According to statistics, accidents in construction are related to the unstable construction of the scaffold in many cases, among which excessive load-bearing accounts for the vast majority. So, how much can a scaffold coupler bear? This article will introduce the bearing capacity of scaffold fastener.

How scaffold couplers can play a load-bearing role?

A scaffold coupler is a mechanical frame structure with a simple single-span structure and clear force, which is composed of all stressed members. Small crossbar, large crossbar, and vertical bar constitute the load-bearing frame. The main purpose of the cross-bracing and pull-out joint is to ensure the overall stiffness and stability of the scaffold and increase the ability to resist vertical and horizontal forces. The pull-out joint is to bear and transfer all the wind loads. The way of load transfer on the outer frame: all the vertical load on the scaffolding piece acts on the vertical and horizontal bar, and is transferred to the vertical bar through the fastener, and finally transferred to the foundation by the vertical bar. The horizontal wind load is transmitted to the building through the pull node.

What are the load-bearing requirements of scaffolding?

OSHA requires that a scaffold be able to support its own weight and four times the maximum intended load. Ropes for suspended scaffolds must support six times the maximum intended load. If you are using a manufactured scaffold, the load you may place on it will be identified.

Coupler products used in scaffold erection mainly include right-angle couplers, swivel couplers, and butt couplers. The bearing capacity of different couplers is different.

Let's take a look at the bearing capacity of these three kinds of scaffold fasteners. Butt couplers are 3.2KN, right-angle couplers and swivel couplers are both 8KN. Generally, the anti-sliding bearing capacity is required to be 20% off. Because the anti-sliding test of fasteners is always unqualified, in some places, for the sake of safety, the anti-sliding bearing capacity is calculated by 60% off. It can also be calculated according to the actual test data which can reach all qualified anti-sliding forces. Note: the tightening torque value of the fastener bolt shall not be less than 40N-m, and shall not be greater than 65N-m.
