2 4 ollo- by Lindapter ollo- igh Clamping Force Lindapter ollo-s are available in two versions; the original standard design for general hollow section connections and larger sized igh Clamping Force () for higher strength structural connections. ECKING FIXING UPPORT FIXING FLOOR FIXING OLLO-OLT LIFTING POINT RAIL FIXING GIRER CLAMP IZE M8, M1 AN M12 IZE M16 AN M2 tandard ollo- A typical connection is made by inserting the ollo- into the pre-drilled holes of the fixture and hollow section. As the bolt head is tightened, the cone is pulled up the bolt thread, causing the sleeve to expand until the cone locks the sleeve against the hollow section s inner wall. At full tightening torque, a clamping force is established between the fixture and the steel section to form a secure connection. Once installed, only the head and collar are visible. = Clamping Force ollo- y working closely with tructural Engineers and teel Fabricators, Lindapter identified the need for the larger M16 and M2 ollo-s to have an increased clamping force suitable for higher strength structural connections. This led to Lindapter s invention of the igh Clamping Force () design, optimised for superior performance. The mechanism consists of a special rubber washer that compresses during installation to significantly increase the clamping force between the connecting steelwork, when compared to a product of the same size without the mechanism, thereby reducing displacement. = Clamping Force Collar leeve (Expands during installation) ee how to install the ollo- on page 44 or watch the video at Mechanism Collar leeve (Expands during installation) Cone (Interlocking grooves prevent loosening) IG ee how to install the ollo- on page 44 or watch the video at Cone (Interlocking grooves prevent loosening) +44 () Lindapter International 216

3 ollo- Clamping Force ollo-s are optimised for structural connections and the larger M16 and M2 sizes feature a igh Clamping Force () mechanism. The graphs below compare the performance of a ollo- and an expansion bolt of the same size without the mechanism. ollo- by Lindapter 41 Clamping Force Typical Performance Increase M16: Up to 3 times more clamping force Clamping Force (kn) isplacement Typical Performance Increase M16: Connection Load vs isplacement Load (kn) Time (minutes) isplacement () afe orking Load ollo- (ith Mechanism) ot ip Galvanised, 2 M2: Connection Load vs isplacement The graphs above show the significance of increased clamping force. The blue curve demonstrates the superior performance of the ollo- in contrast to M16 and M2 sized products without Lindapter s patented mechanism. At afe orking Load, displacement (movement in the connection) is minimised when using the ollo- for a safer and more secure connection. Load (kn) (ithout Mechanism) ot ip Galvanised, 2 M2: Up to 3.5 times more clamping force As with any structural bolt, iediately after installation the bolt relaxes until a typical clamping force is reached. The typical clamping force of the ollo- () is over three times higher than the same sized product without the mechanism. This results in a more secure connection and a greater force that has to be overcome before displacement begins.

The characteristic values are used to determine the design resistance of the ollo-. The design resistance is calculated by dividing the characteristic value by a partial factor γm2. The partial factor is a nationally determined parameter (eg: γm2 = 1.25 in UK). For ollo- safe working loads with a Factor of afety of 5:1 please refer to the tables on page 42 of this catalogue. The characteristic values are valid for the assembly itself, in any connection detail the design resistance of the connection may be limited to a lesser value. For example, when the thickness of the connected component is small, pull out failure may occur before failure of the ollo-. esign checks should be carried out to determine the static design resistance. The CI Greenbook publication Joints in teel Construction: imple Joints to Eurocode 3 contains a number of checks on the section. The characteristic values are only valid when the ollo-s are installed as per Lindapter s installation instructions.
