Post Tensioning System Product Description Prestressing force is the compressive stress applied to a structure in advance during construction in order to improve the service performance of the structure. Prestressing force is the compressive stress applied to a structure in advance during construction in order to improve the service performance of the structure. Pre-added compressive stress during the service period of the structure can fully or partially offset the tensile stress caused by the load, avoiding the destruction of the structure, and is commonly used in concrete structures. The Concept of Prestressing Force 1. Prestressing force is the stress applied to the member before loading; 2. Prestressing force makes full use of the compressive strength and tensile strength of the material, and can improve the crack resistance of concrete, but will not improve the load carrying capacity of the member; 4. The inverted arch of the member caused by prestressing can offset the deflection of the constant load, but it has almost no effect on the deformation caused by variable loads; 5. prestressing is an internal force in the member, which does not destabilize the member, but rather improves the stability of the member. For example, prestressing can be applied to precast piles to improve the stability of the piles during transportation and pile driving; A prestressing system usually consists of several components, including anchor, wedge, strand, and bellows.

Post Tensioning Anchor Product Description Post Tensioning Anchor is a kind of anchorage suitable for concrete prestressing tensioning in the process of engineering and construction. It is an anchorage tool for maintaining the tension of prestressing tendons and transmitting it to the inside of concrete in post-tensioning structure or member. anchorage tool for maintaining the tension of prestressing tendons and transmitting it to the inside of concrete in post-tensioning structure or member. Application of Post Tensioning Anchor Post Tensioning Anchor is generally used for highway bridges, railroad bridges, urban interchanges, urban light rail, high-rise buildings, water conservancy prestressing anchors, dams, ports and terminals, rock retaining anchors, foundation reinforcement, tunnels, tunnel mine roof anchors, prestressing nets, subways, large halls, warehouses, factories, towers, large containers and ships, sleepers, and replacement of bridge bearings, Bridge and building reinforcement, steel reinforcement works, antimagnetic and anticorrosion works, carbon fiber reinforcement, pre-tensioned girder field construction, extracorporeal pre-stressing works, inclined cable, suspension cable and so on.

Product Description The RuiYi post-tensioning wedge is a crucial component used in prestressed concrete structures. By applying prestressing force on the concrete elements, it significantly enhances the load-bearing capacity and durability of the structure. Working Principle of post tensioning wedge By utilizing the taper of the anchor ring and the prestressed anchor plate, a significant clamping force is generated on the steel strand, creating a strong gripping force. The clamping-type anchor system generally utilizes the frictional resistance between the prestressed anchor plate and the steel strand to secure the steel strand. The porous prestressed anchor plate system, also known as a cluster anchor system, consists of porous prestressed anchor plates, anchor bearing plates (also known as cast iron bellows, anchor seats), helical bars, or steel mesh sheets. This type of anchor is implemented on a multi- porous anchor plate, with each conical hole holding a pair of prestressed anchor plates to clamp a steel strand.
