General Presentation

Strukturas, your partner for turnkey projects, worldwide.

Strukturas was founded in 1991 as a continuation of Olav Opedal AS, an Aker owned company specializing in construction and mechanical engineering.

Strukturas history therefore dates back to the 1960s with long standing traditions and

considerable experience.

• in situ casting of full spans

• TT or box cross sections decks

• Special solutions for special bridge

projects

• Hydraulic operated main functions

• Labor saving solutions

• Easy to adjust to radius, slope and

span variations

• Easy installation of the rebar deck

prefabricated parts

• Can be made symmetrical

Movable Scaffolding System Overhead Solution

NEXTPREVIOUS

• Supported on top of columns

• External formwork panels suspended

by hangers and threaded bars from

MSS main structure

• Formwork can be designed in special

cases to open horizontally like in a

drawer rather than rotate around the

hangers

• Can be made symmetrical

• Usually easier to assemble behind the

abutment

• Usually easier to move from one deck

to the parallel one

• One concept

• Many different applications

• Usually made to max. 5m length segments, but may be made to measure

• Segment weight typically range in between 80ton and 550ton

• Easily adjustable to the segment variations

• Reduced weight, saving prestressing

• Easy to assemble

• Simple solution to support the precast concrete segments

• Two independent halves only connected by the gantry crane, allowing to easy transversal adjustments

• Hinge connection makes possible to be used at decks with horizontal radius as small as 75m

• Hydraulic underslung supports allows correction of any misalignments

PREVIOUS

• Solution especially suitable for situations where the space bellow the deck is limited and also if there are significant variations in the deck width

• The Combo Launching Gantry version allows for the assembling of precast segments both by the in fill method and the cantilever method

• Utilization of special hinges to run the system with horizontal curves up to 350m and spans lengths above 50m

Segmental Form

• Simple steel supporting structure equipped with a lifting unit

• The lifting unit can be equipped by winches or strand jacks depending of the elevation height and segment weight

• Launching and leveling hydraulic operated

Full Span Launching Method

Full SpanLaunching Method

MENU END

• Especially suited for projects that require minimal deck deformations and fast construction

• The Full Span Launching method is part of a wider set of devices that operate all together as the gantry crane/straddle carrier and the special multi wheeled transporters

• Capacity: 500-1800ton

• Spans up to 60m

Beam Launcher

Beam Launcher

MENU END

• One of the most commonly used construction methods for standard bridges

• Cost efficient, fast and technically flexible solution

• Specially suitable for bridges and viaducts with very high columns and difficult access conditions
