Esolution adds Prestressing bars to its products range to the market, the application range as follows:
Reinforcing systems
Mining
Geotechnical systems, Anchors,
Anchors are always used in situations in which high tensile forces must be transferred into the ground. Typical applications include, for example, anchoring of excavation sheeting or retaining walls, slope and rock stabilization or anchoring for bridge abutments or wind turbine masts.
Geotechnical systems, Soil Nailing
the principle of soil nailing consists in installing reinforcements in the form of bars (soil nails) into the natural soil in order to increase the tensile and shear strength of the ground. This creates a monolithic compound structure whose load-bearing property is like that of a gravity retaining wall loaded by external forces.
Hollow-bar nails
consist of three main components: the nail head, the steel tendon – including sleeve and single-use drill bit – and the grout body. The steel tendon is a hollow steel bar with cold rolled round thread and can therefore be cut or joined at any desired point, available products for both use permanent and temporary applications
Solid-bar nails
consist of three main components: the nail head, the steel tendon and the grout body. The steel tendon is a round steel bar with coarse, hot rolled thread ribs and can therefore be cut or joined at any desired point, available products for both use permanent and temporary applications
Tunneling
Anchors, Strand anchors
consist of three main components: the anchor head, a steel tendon - divided into the bond section and free length - and the grout body, The steel tendon is constructed from a number of 7-wire prestressing strands,
Anchors, Bar anchors
consist of three main components: the anchor head, a steel tendon - divided into the bond section and free length - and the grout body, The steel tendon is a round steel bar with coarse, hot rolled thread ribs and can therefore be cut or joined at any desired point.
available for both temporary with service life up to two years and permanent applications up to 100 years
The prestressing force applied to the anchor head using hydraulic equipment is introduced through the freely extensible prestressing tendon and the grout body into a load-bearing soil layer. The created anchoring force then acts actively on the anchored building component and the anchor does not require a displacement of the anchored component in order to become effective.
Posttensioning systems,
The post-tensioning system is frequently used in the restoration and strengthening of buildings, with a complete prestressing systems for structures: tendons with internal bonding, without bonding and with external tendons, For very short prestressing tendons, smooth steel with a fine rolled thread is used because of its very low slip rates.
Internal tendons
with bonding are used primarily in concrete, composite and masonry structures. Internal tendons without bonding and external tendons are typically used in transverse prestressing, for bridge improvements, in renovation, as a joining element for steel structures and machines and for temporary anchoring.
Formwork ties, steel tendon
together with accessories specific to the particular application. The steel tendon is a section of round bar steel with coarse, hot-rolled thread ribs. This can therefore be cut or joined at any desired point.
Micro piles are a deep foundation elements with a small diameter of up to 300 mm, by means of which loads from the superstructure are transferred to lower-lying, load-bearing soil layers through skin friction.
Micro piles can transfer tensile, compression and alternating loads. Typical applications are the foundation or strengthening of existing foundations of structures (e.g. buildings, bridges, retaining walls, masts etc.) or uplift restraint for structures in groundwater.
