🔴 OVERHEAD MSS - Movable Scaffolding System 🔴
💪14 DAY TYPICAL CYCLE PER BRIDGE SPAN 💪


✅Overhead MSS is another Movable Scaffolding System solution that is also suitable for concreting span by span BOX or DOUBLE T DECK sections.

✅Box Overhead MSS typically consists of a resistant structure supported by the columns, from where the formwork is suspended. The resistant structure normally includes two main I-beams, a set of transverse beams and the noses and supports.

✅When the solution is used for concreting box section decks, the internal formwork is identical to the internal formwork used in underslung MSS.

✅The Overhead MSS main supports are designed in each case to adjust to the geometry of the columns in each project and the way the reactions should be transmitted to the concrete.

STRUKTURAS has extensive experience in designing different support configurations for overhead MSS.
The most common support solution consists of assembling support legs directly on the column, in which case the legs are connected to the concrete using embedded anchors.
Other solutions less frequently used have profiles passing through the column walls, collar friction or even precast concrete legs which becomes lost inside the deck structure.

🏗 Underslung Form Traveller Ariari
Puerto Lleras, Meta, Colombia

Connecting the downtown area of Puerto Lleras with the existing Vista Hermosa county road, known as “Trocha Siete” with a bridge over the Ariari River.

It is a cable-stayed bridge with a length of 270 m, made up of spans of 70 m, 135 m and 70 m and a deck width of 11.6 m. Bridge supported by two pylons approximately 52 m high and 20 m wide at the base.

The superstructure is made up of a concrete slab that is supported on longitudinal and transverse by structural steel beams.

Balanced cantilever construction method of the deck - Cast-In-Situ with Form Travellers.

🔴 The Underslung Form Traveller solution can be adapted to different types of bridge decks, such as arch bridges and cable-stayed bridges, leaving enough room to assemble the temporary or final cable stays, and allowing easy launchback to the initial assembly position.

The external formwork of this type of Form Traveller is supported by the main structure, leaving enough room to install the pre-assembled rebar cage. When the rebar cage is pre-assembled, the Strukturas Underslung Form Traveller is the perfect choice.

MSS steht für “Movable Scaffolding System” und der Name ist Programm: Entwickelt für Brücken und Viadukte aus Ortbeton, lässt sich die Vorschubrüstung von effizient und sicher bewegen. 🌉 Durch den Einsatz von MSS können die bestehenden Autobahnen und Schienenwege während des größten Teils der Bau- oder Abrisszeit offenbleiben. Gleichzeitig handelt es sich um ein Brückenbausystem, das sicheres Arbeiten ermöglicht.

Die Vorschubrüstung gibt es in unten und oben laufender Ausführung, so dass die Bauarbeiten sowohl oberhalb als auch unterhalb der Brücke durchgeführt werden können. Beide Ausführungen nutzt für den Neubau oder Abbruch von Straßen- und Eisenbahnbrücken. Die Systeme eignen sich hervorragend für die Ortbetonage ganzer Spannweiten.

✅Ein obenliegendes MSS hat den Vorteil, dass es hinter den Widerlagern in Bodennähe installiert werden kann.

✅Underslung MSS bietet die Möglichkeit, freien Platz für die Bewehrungsinstallation zu haben. Außerdem kann der Turmdrehkran auf dem MSS platziert werden, um mobile Kräne für Installationsarbeiten zu ersetzen. 🏗

Underslung MSS - Movable Scaffolding System
☝ Box section - one phase casting 14 day typical Cycle



✅ The Underslung MSS solution is currently used in the span by span construction of the cast-in-situ bridges and viaducts decks, with spans normally varying between 20 m and 70 m.

✅ Concreting each box section span using Underslung MSS can be done in one or more stages, depending on the deck design.

✅ The versatility of the Underslung MSS solution makes it possible to be used on decks with a variable plan view radius and up to minimum of 250 m to 300 m.

Each underslung MSS normally consists of: a resistant steel structure, supporting brackets, suspension gallows, a set of working platforms and ladders, internal and external formwork, high resistance threaded bars, bolts, pin bolts and hydraulic systems that allow the MSS to be launched and formwork to be opened and closed, as well as making the necessary geometric adjustments.

The MSS noses are hinged in relation to the main girders, making it possible to adjust to relatively small, fixed or variable plan view curvature radius.

✅ The Strukturas MSS system is developed in 1971 by Engineer Tore Gjolme, who founded Strukturas as in 1991. He is 78 years old and still going strong and working daily at Stukturas office with team!
Due to constant succession Strukturas team accumulated more than 50 years of bridge building equipment engineering legacy from Strukturas founder Engineer Tore Gjolme.
This is the reason of Strukturas technical professionalism.
