PRE TENSION

PROPERTIES

Prestressed Anchorage Systems

The self-drilling anchor bolt device (also known as Threaded Hollow Bars) makes your job much easier, as it is capable of performing procedures of drilling, anchoring and injection all at once. There is a hollow interior of the self-drilling anchor bolt, a threaded exterior and a drill bit that is used for drilling.
The self-drilling anchor bolt’s hollow interior enables air and water to freely move through the drilling process, flushing the particles. After completion of the drilling process, it also enables immediateinjection. For fractured or hard rock formations as well as uneven ground conditions (such as
gravel, soft, clay and non-homogeneous soil), self-drilling anchor bolts present a specific bolting solution.

Anchorage Heads

BWC Multi-String Prestressed Systems, have been used for years in the construction of bridges, buildings, tanks and many other structures that require engineering reinforcement and support elements. BWC provides Design and Development, Engineering, Production and Supply Installation, Technical Training, Installation Supervision, Inspection or Maintenance services for Prestressing Systems. BWC Pre Stressing Systems are known for its superior load bearing performance, durability and simple design. BWC Pre Stressing Systems significantly contributes to long life of structures by virtue of its high-quality corrosion protection methods. They are used on slopes such as BWC Anchor and Pile Systems and related
product lines and for geotechnical applications as excavation stabilization in a wide range.

Anchor Grips

Diameter and number of the tendon materials, dimensions of load distribution plate, diameter of anchor head and number of holes, number of anchor grips are calculated according to the anchor loads depending on the project. BWC anchor heads are available in all sizes and diameters in our stocks.

Anchor heads and grips are designed according to types and number of spiral steel ropes that form the tendon. Threaded grip clamps-grips are used to fasten the anchor tendons to head plate.

The diameter and number of tendon material, the size of load distribution plate, the diameter and hole number of anchorage head, the number of anchorage wedges are calculated according to the anchorage loads in accordance with the project. You can supply the anchorage heads in BWC brand in any height and diameter from our stocks. The anchorage heads and grips are designed according to the type and number of spiral steel ropes which make tendon. The grip clamps-wedges (grip) are used to fix the cover plates of the anchorage tendon.

Anchorage Plates

BWC produces plates in desired dimensions in line with the measurements and demands in the project.
BWC Anchorage Plates can be prepared as special production according to demand and need in addition to standard holes.
In addition, the plates can be made of stainless steel on request for projects that are sensitive to corrosion. For protection of plates and threads, BWC recommends protective hats suitable for your project.

Protective Accessories

They are protective accessories to protect the threads and delivered products and to take measure against rusting. It is placed in the center of the stud and prevents the product from sliding.

BWC manufactures the plates in requested sizes according the measurements and demands in the projects. BWC anchorage plates may be prepared in accordance with the demands and needs as a special production as well as the standard drilled holes.
In addition, the plates may be manufactured from the stainless steel according to the demands for the projects including the
sensitivity to corrosion. BWC suggest the protective caps appropriate for your Project to protect the plates and grips.

Tensioning Anchors

Pre Tension tensioning anchors help to anchor and stretch the ropes. These are designed according to the
principle of anchoring each rope individually by means of compressors. The prestressing force is transferred to concrete by a rigid anchor plate.The spirals surround too much concrete in the zone behind the anchor plate. The tensile forces in the anchor zone should be met with an additional soft reinforcement

The reinforcement is determined by considering the shape and dimensions of the anchor plate as well as
the dimensions of the end region. Stretching anchors can also be used as fixed anchors. In this case, the anchor head must remain stable during the tensioning process.
