Tanrimine Metal Support Co., Ltd.

FB-47 SPLIT SET BOLT (Friction Stabilizer)

Short Description:

FB-47 Split Set Bolt is used as a main support friction bolt stabilizer for underground or above ground projects in mines, tunnels or slopes or wherever reliable ground support is needed, especially in mechanised jumbo development and production. Our FB-47 Split Set Bolt was made by high strength steel strip which special refined with very low level of Si & P in chemical components, it will make the bolt in perfect performance of supporting rocks, and help to have a good quality in galvanizing. Meanwhile, with our advanced PLC-controled auto welder, the bolt will has a very good performance when it is inserted in the rocks.

FB-39 SPLIT SET BOLT

As a main reliable ground support Split Set Bolt used in applications, Dia.47mm C pipe of bolt body is the most crediable and reasonable size which can offer a perfect and safety way for ground support, so it is widely used in mines, tunnels and slopes etc. However meanwhile, the material strength and characteristic, and the welds quality between ring and the C tube, become critical points on the .

FB39 Split Set Bolt weld quality

Welds quality is a very critical point for the split set bolt which will affect the performance of the bolt while used in ground support. We have a routine quality mornitoring and warning system to get a consistance and stable perfect welds quality, and a job traveller with pull testing records will go through the whole processes to avoid any accidents in the production.

Galvanizing and Black Split Set Bolt with different length are available. Made by high-grade of steel material, our split set bolt can get a very good zinc coating surface to have a better performance when it is used in corrosive environment.             The standard packing for FB-47 Split set bolt is 150 untis per wooden or metal pallet.

FB-47 SPLIT SET BOLT FEATURES

FB47 Split Set Bolt with Galv Dome Plate

1. What is Combi Plate and how does it make ?
The tubular C shape of the bolt generates a load transfer from the steel to the rock when installed into a slightly smaller diameter hole, and results in a frictional resistance pull-out load of the tube from the hole, and creating a full length radial pressure to the hole by increasing the contact surface of the steel to the rock due to its tubular shape, and when install onto the plate, it establishes a compressive force against the rock. When additional load bearing capacity is required, friction bolt can be grouted by cement grouts.

2. How to use and assemble ?
A pull collar fixing at the ring end enables load testing during the bolt installation. The tapered end of friction bolt can be easily inserted into the drilled holes. Friction bolt can be installed with either hand held or mechanized equipment, such as a jackdrill, a stopper, a roof bolting jumbo, or any other type of drill.
