Prestressed Material
Multi-Strand Anchorage is a permanent anchoring device used in post tensioning structures or components to maintain the tensile force of steel strands and transmit it to the concrete structure or component
The clamp type anchor is to anchor the steel strand using the wedge tightening principle of the conical hole, that is, the wedge shaped clamp anchors the steel strand into the conical hole of the anchor plate. When a jack is used to tension the steel strand bundle and reach the design stress value, the jack slowly releases the tension. The clamp of the anchor is then brought into the conical hole of the anchor plate by the steel strand bundle with uniform retraction movement, forming an anchoring unit, The stress of the steel strand bundle is transmitted to the building structure through anchor plates and anchor pads, forming permanent pre-stress.
ADVANTAGES
Circular tension end clamp type anchors have a wide range of options, commonly used in 1860MPa grade, with diameters of 15.2mm (0.6 ") steel strands and 12.7 (0.5") steel strands, ranging from 1 to 37 pieces; On this basis, the number of steel strands can also be increased to meet design requirements. It has good self anchoring performance and is easy to operate during construction. High anchoring efficiency coefficient, stable and reliable anchoring performance.
SPECIFICATIONS
The circular tension end clamp type anchor consists of four parts: clamp, anchor plate, anchor pad, and spiral reinforcement. The clip is a key component of the anchoring system, which is in the form of a two piece or three piece type and is made of high-quality alloy steel; The anchor plate has a conical hole, which is matched with the clip and uses the wedge tightening principle of the conical hole to anchor the steel strand; The anchor pad and spiral reinforcement together form the load-bearing component under the anchor, and its performance must meet the requirements of bearing and transmitting pre-stress. The main function of the anchor pad is to bear the stress well under the anchor and transfer the stress to the prestressed concrete structure. The main function of spiral reinforcement under the anchor is to constrain the concrete under the anchor and resist concrete splitting, restrain the lateral deformation of the core concrete, and improve the ultimate strain of reinforced concrete axial compression components
