XQV BJM15 Live End Flat Anchorage – Multi-Strand Flat Anchorage for Post-Tensioning

Compact Live End Flat Anchor for Confined Sections – Ideal for Bridge Diaphragms, Slabs & Thin Structures

Product Introduction

XQV flat anchorage system for pre-tensioning or post-tensioning concrete structures features a flat cross-section, which can significantly reduce the height of components, offering distinct advantages in scenarios such as high-rise building floors with limited storey heights. They are compatible with flat corrugated pipes, facilitating the horizontal or inclined arrangement of multiple prestressing tendons, and are commonly used in the transverse prestressing construction of bridges. Paired with specialized flat jacks, they can operate in confined spaces, reducing the depth of grooving and improving construction efficiency. Their design ensures uniform stress distribution, effectively enhancing the crack resistance of components. They are also compatible with single or multiple steel strands in 1-5 holes and various prestressing systems. Additionally, by reducing the amount of concrete used and the self-weight of components, they can lower the overall cost of long-span structures.

Application

XQV BJM15 Live End Flat Anchorage is specifically designed for post-tensioning applications where structural height is restricted. Its flat configuration allows reliable anchorage in shallow concrete members. Typical applications include:

Bridge Transverse Post-Tensioning: Used for transverse prestressing of bridge decks, box girders, and segmental bridges. The flat anchor fits within limited vertical space while anchoring multiple strands.

High-Rise Building Floors: Applied in post-tensioned flat slabs and band beams where storey height is limited. Reduces structural depth while maintaining load capacity.

Parking Structures: Used in post-tensioned slab systems of multi-story parking garages, minimizing floor thickness to reduce construction cost.

Beam-Column Joints & Transfer Girders: Anchors prestressing strands in heavily reinforced, confined areas such as transfer girders and deep beam-column connections.

Thin Concrete Slabs: Ideal for ribbed slabs, hollow-core slabs, and other shallow concrete members requiring efficient prestress transfer.

Structural Strengthening: Applied in external post-tensioning for strengthening existing beams and slabs, where shallow anchor heads are required to avoid interfering with building finishes.

Long-Span Structures: Reduces concrete usage and component self-weight, lowering overall construction cost for bridges and large-span buildings.
