Product Description

1. Definition and Function

The prestressed flat anchor clip is a pivotal component in bridge construction, acting as a linchpin within the prestressing system. By preloading the structure through tensioned steel strands, it significantly amplifies both load-bearing capacity and crack resistance. This clip ensures seamless engagement with steel strands, employing the wedge principle to firmly anchor the strands to the anchor plate, thus securing the essential prestress.

2. Structure and Principle

• Structure: Ingeniously designed as a conical frustum, the clip features a narrower top and a broader base. Its inner cavity is precision-machined, often incorporating threads or tapered threads for optimal steel strand engagement. The outer conical surface aligns perfectly with the inner conical hole of the flat anchor plate. Some models boast machining slots at the larger end, typically 3-5mm deep, while the smaller end is fitted with pin holes, allowing installation perpendicular to the clamp's outer wall, usually equipped with three pins.

Principle: The magic unfolds during prestressing, where the jack induces tension on the steel strand. Upon reaching the design threshold, the clamp instinctively wedges inward, nestled between the tapered anchor plate hole and the steel strand. This anchoring feat is achieved through the robust frictional forces between the clamp, the steel strand, and the anchor plate's tapered hole, ensuring the enduring integrity of the prestress.

3. Material and Performance Requirements

Material: Crafted from high-grade alloy steel, the clip boasts exceptional strength, resilience, and toughness. This ensures it withstands immense stress without succumbing to brittle fractures or undue deformation, guaranteeing durability and reliability.

Performance Requirements: The clip is engineered for impeccable anchoring prowess, ensuring the steel strand remains steadfast without slipping or loosening. It excels in anti-fatigue performance, adapting effortlessly to the dynamic load conditions of bridges, including repeated vehicular loads. Additionally, its corrosion resistance enhances its longevity, making it a vital asset in bridge construction.

4. Application Scenarios

The flat anchorages and clamps shine in slab structure bridges, where prestressed steel strands must be flatly arrayed to maintain a sleek profile, avoiding increased plate thickness. They are indispensable in urban elevated bridge decks, small prestressed concrete slab bridges, and similar structures, ensuring robust structural integrity.

5. Key Points of Construction

Pre-installation Inspection: Meticulously inspect the clip's surface for any imperfections, such as cracks or burrs. Ensure a flawless fit between the clip and the anchor plate's tapered hole for smooth, tight engagement.

Installation Process: Accurately position the clip within the anchor plate's tapered hole, guaranteeing even distribution and optimal contact with the steel strand to ensure a secure fit.

• Tensioning Operation: Follow the meticulously designed tensioning program and process. Vigilantly monitor the clamp throughout the tensioning phase to avert issues like misalignment and jamming. Post-tensioning, verify the clamp's anchoring to confirm the steadfast integrity of the steel strands.
