摘要： A method and system for forming a post-tensioned concrete slab using a post-tensioning concrete anchor. The system may comprise a connector anchor including a bore that includes a first frustoconical portion, and the connector anchor may be adapted to bear on the post-tensioning concrete anchor. The system may also comprise a coupler comprising a connector and a coupler body that includes a second frustoconical portion that is oriented oppositely to the first frustoconical portion. The connector may have a bore therethrough and may be configured to receive the coupler body and to engage the connector anchor. A pocket-forming cap may releasably engage the post-tensioning concrete anchor; the pocket-forming cap may include a frustoconical wall, a gripping head, and a connector-receiving portion. The method may include using the system to form a second concrete section adjacent to a first concrete section before stressing the first concrete section.

摘要： A one-piece post-tension tendon pocket former includes a pocket section configured to create a pocket in an edge of concrete, a formwork securing mechanism connected to the second end of the pocket section configured to secure the second end of the pocket section to a formwork, and an anchor securing mechanism. The anchor securing mechanism is configured to secure the pocket section to a post-tension tendon anchor with at least one fastener hole and includes an anchor sealing portion and at least one retention tab. The anchor sealing portion is configured to seal the pocket section to the post-tension tendon anchor. Each of the at least one retention tab extends from a side of the pocket section and is configured to be secured in one of the at least one fastener holes for securing the seal between the anchor sealing portion and the post-tension tendon anchor.

摘要： Ultra-High-Performance Concrete (UHPC), owing to its superior mechanical and durability properties, presents a unique opportunity for innovative use in unbonded post-tensioned floor systems. In unbonded post-tensioned (PT) slabs and beams, the use of cast-in-place steel confined UHPC Bond Anchors (UBA) can be used to anchor steel prestressing strands for better durability, increased strand ductility, cost-effectiveness, and ease of installation. A conical, steel confining device is used as part of the UBA. The device resists hoop tension and eliminates splitting cracks in the UHPC during prestress transfer. It also helps to reduce the anchorage length. High average bond stress helps reduce the UBA length, and consequently, the material consumption. The bond stress at the strand-UHPC interface can be increased by intentionally roughening or indenting the strand.

摘要： A method for producing a three-dimensional construction material component preferably having at least one curved surface. A plurality of spacers are arranged in a formwork. A textile reinforcement is supported on the spacers, such that the textile reinforcement has a defined position within a formwork interior of the formwork. A tensile force is applied via a tensioning device to the textile reinforcement in at least one tension direction. Construction material is introduced into the formwork interior and surrounds the textile reinforcement. The construction material is then hardened, wherein the tensile force is maintained during the hardening. During this process, the spacers are integrated into the construction material component. The tensioning device has at least one clamping unit for clamping an end portion of the textile reinforcement between two clamping surfaces. The clamping surfaces are provided on clamping insert bodies, which are of a plastic material of a defined hardness.

摘要： A method of construction of composite wall module system in which a first wall module and a second wall module are coupled to the first wall module by a vertical joint. The vertical joint is comprised of plurality of anchors and reinforcement bars as well as steel side plates allowing composite wall steel faceplates to be discontinuous across the vertical joint. The faceplates of the first and second modules are not made continuous across the vertical joint through continuous welding. The vertical wall joint further includes fill disposed between faceplates and side plates adjacent to anchors and reinforcement bars.
