Advantages of the Hollow Bar Corrosion Protection System
In order to extend the service life of hollow bar, it can be dealt with corrosion protection. The corrosion protection system provides the design engineer and the owner with the possibility to easily and permanently protect tension members against corrosion. In particular, the following advantages are evident:
1. Applicable with new tension members or with tension members that are already in use
2. The hollow bar's corrosion protection system is based on the DENSO corrosion protection technology that has been successful for decades
3. The hollow bar's corrosion protection system is proved during tests at the material testing
4. The quality assurance according to ISO 9001
5. Robust multi-layer system with a layer thickness of at least 2,6 mm
6. Elastic properties which can support deformations of the tension member without damages
7. Any irregularities in the surface of the tension member are filled
8. Good adhesion of the hollow bar corrosion protection tape on the surface of the tension member
9. Positive impact on the behavior of tension members in rain-wind-induced vibrations, achieved through helical application of the corrosion protection tapes
10. The hollow bar can be dealt into different colors.
11. Simple and competitive assembly through the wrapping method especially developed for this purpose
12. No enclosure, scaffolding or other equipment such as working platforms or lifts are required
13. Short assembly time as no waiting time and curing time must be respected between the application of the several layers
14. Widely independent of weather conditions during assembly. A dry surface is the only precondition
15. Ecologically friendly assembly due to the omission of blasting works
16. No flaking or tearing of the wrapping, e.g. after a possible emission of cable filler at full locked cables or at relative displacements between single wires of the cable
17. Easy visual control for damages on the corrosion protection surface
18. Damages can easily be repaired by wrapping an additional layer of tape

Sinorock Will Join the CONEXPO-CON/AGG Exposition
The CONEXPO-CON/AGG exposition is the global industry gathering place. It is also the largest gathering in North America for the construction, construction materials and fluid power/power transmission/motion control industries. It is held every three years and the next session will be in March, 2014 in Las Vegas.
In 2011, the exposition attracted nearly 120,000 registered attendees. In 2014, CONEXPO-CON/AGG will represent an immense unveiling of all the newest equipment, technology and product breakthrough in construction. Over 130,000 industry professionals will be at the show.
Sinorock® will join the CONEXPO-CON/AGG exposition. It will be the first exposition of Sinorock. On this exhibition, Sinorock will show Self drilling anchor bolt, Expansion Shell Anchor Bolt, especially Large Diameter Anchor Bolt. Also, we have new picture album that can help you realize our company very well.
We sincerely look forward to your coming.
Time: March 4-8, 2014
Address: Las Vegas, USA

Friction anchor bolt theory and Sinorock friction bolt
Friction Bolts is a kind of anchor bolts which is specially used in strong support. It is also a kind of advanced materials in underground culvert roof and other projects support. Friction bolt has the features of simple operation and easy use. When installing in spraying anchoring support of the underground support, this kind of anchor bolt has strong anchorage force, large pulling force and big expanding force which makes the whole roof into a complete one to support the stress of the surrounding rock. Friction anchor bolt is a new kind of anchor bolt which has the whole length of anchorage and active reinforcement of the surrounding rock. Its anchor bar is a high strength tube of the vertical slit. When installing in a drilling hole with a larger diameter than that of the anchor bar, friction anchor bar will make big pressure on the wall of the drilling hole and friction preventing the surrounding rock slipping in the whole range. The pressure force, friction force and the supporting force of the anchor plate make the surrounding rock in a stressed state in three directions and achieve the support to the surrounding rock. Under the conditions of anchor bar moving because of blasting vibration, the anchoring force will be increased obviously. When the surrounding rock moves clearly, friction anchor bolt will not loss the supporting force.
Sinorock’s Friction Bolt improves rock stability and safety factors by tightening as lateral strata movement occurs. The Friction Bolt is primarily used in metalliferous mining operations, but is also well suited for rib support in coal operations. Sinorock’s Friction Bolt is available in three sizes:33mm，39mm and 47mm
Installation Procedure:
1. Drill hole at proper diameter and depth. Diameter is determined by on-site testing.
2. Insert Friction Bolt into the hole. A driving tool is fitted into the rock drill’s chuck. Place Friction Bolt and plate onto the installation tool.
3. Using percussion and thrust, fully drive the Friction Bolt into the hole until the Dome Plate is tight against the rock surface.

Applications of friction rock bolt
Friction hollow anchor bar consists of two parts, a tube and matching domed bearing plate. It is mainly used as a good ground support products in coal mines, copper mines, subways and tunnels, etc.
During the using process, immediate ground support is good for friction rock bolt. But soft rock strtas is not so suitable. so, permanent support and roof support is also not recommended.
The Drilling Hole for Friction Rock Bolt should be cleaned and examined to ensure the friction bolt will insert smoothly. Variation in hole daimeters(due to differing strentths of rock strata or excessively gragmented ground) can yield variations in anchorage capacities at various elevations.
Sinorock Friction anchor bolt completed with dome plate has very high strength split tube with welded ring, which guarantees for very good & typical Lab Pull Test.

The features of anchor bolt
When it comes to the erection of metal building systems, one of the most important aspects is the location of the anchor bolts in the foundation. The incorrect placement or embodiment of anchor bolts can lead to costly errors, or even fatal accidents.
Anchor bolt is used in construction where these are set in walls & columns for supporting ledgers, beams, plates. Further, it is also used for prefabricated concrete panel construction for aiding connection to structural frames.
Some other uses include for attaching stair risers or frame assemblages where these provide for strong and durable support. Here are the features of anchor bolt:
1. They are capable of supporting very large loads.
2. Drilling or cutting of reinforcement is not required for installation.
3. Strength is not sensitive to installation procedures and techniques.
4. Supplementary reinforcement may be easily included in the design.
