🔴 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.

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.

Gemeinsam stark im Brückenbau – das ist die Philosophie von Hünnebeck und Strukturas. 💪
Dafür besonders geeignet sind Freivorbaugeräte von Strukturas, die als wirtschaftliche und vielseitige Schalungslösung den Bau von Spannbetonbrücken im Freivorbauverfahren ermöglichen. Als oben laufendes Freivorbaugerät ist es die am häufigsten verwendete Lösung für das Gießen von Brücken- und Viaduktdecks, deren Spannweite zwischen 60 und 250 Metern liegt. 🏗️
Unten laufende Freivorbaugeräte können an verschiedene Arten von Brückendecks angepasst werden, wie z.B. Bogen- und Schrägseilbrücken. Es lässt genügend Platz für die Montage der provisorischen oder endgültigen Schrägseile und ermöglicht ein einfaches Zurückfahren zur ursprünglichen Montageposition. ⚙️

#Brücke #Vorschubrüstung #Rückbau #SpanBySpan #Bridge #Demolishing using the MSS - Movable Scaffolding System Contractors Eiffage , Implenia and Arlt Bauunternehmen GmbH are using this demolition method for their client Die Autobahn The demolition of the old bridge with MSS is an effective and safe solution: - Minimal intervention to existing infrastructure. - Using MSS for demolition allows the existing highway to remain open throughout all of the demolishing period. - MSS allows the existing railway to remain open throughout most of the demolishing period. - The MSS could be assembled on the ground and later could be lifted with 4 strand jacks. - After finished demolition MSS could be lowered with 4 strand jacks on the ground for safe and productive MSS dismantling. - The challenging MSS installation conditions can be carried out by professional site crew from Strukturas. - The engineering challenge is to avoid an overload of the superstructure during the demolition and to ensure a safe load transfer within the load capacity of the MSS. - After the demolition this same MSS could also be used for the construction of the bridge deck. This approach saves time and resources, making the construction process more efficient.

⛔ DEMOLITION OF THE WERNTAL BRIDGE ⚒ USING MOVABLE SCAFFOLDING SYSTEM - MSS #SpanBySpan #Bridge #Demolishing ✅ The existing Werntalbridge on the highway A7 north of Würzburg (Germany) had been demolished and replaced with a new bridge. The bridge is 460 m long and made with two parallel decks with 8 spans. Moreover, the maximum span length is 59,5 m and the deck width is 15,2 m. Demolition of the the old bridge and the construction of the new Werntalbridge was awarded by Die Autobahn to the contractor Arlt Bauunternehmen GmbH . ✅ Movable Scaffolding System ensures the minimal intervention to existing infrastructure. Using MSS for demolition allows the existing highway and the railway below the deck to remain open throughout most of the demolishing period. The MSS was assembled on the ground, later the MSS was lifted with 4 strand jacks and finally launched to the first span. ✅ The total weight of each of the 59,5m long spans is 1600 tons ❗ ✅ The engineering challenge - to avoid an overload of the superstructure during the demolition and to ensure a safe load transfer within the load capacity of the MSS. ⁉ Highlights & Facts: Max Span: 59,445m Max MSS Span: 59,445m Weight of Superstructure: Approx 267 KN/m Width Of Bridge Slab: 15,2m (MAX) Min.Hor.Radius: R= NA Max Crossfall: 2,5% Max Long Slope: 2,0% Deflection of MSS: MAX L/400 ☝ The demolition of old bridge structures with MSS is an effective and safe solution for many bridges ❗☝ 💡 If you would like to learn more about bridge demolition using Movable Scaffolding System, send us a private message and we will contact you as soon as possible STRUKTURAS WE MAKE IT SIMPLE! #Brücke #Vorschubrüstung #Rückbau #Bridge #ConstructionMethods #Concrete #Project #Innovation #Engineering #Technology #Sustainability #Productivity Aquilino Raimundo Linas Adomavičius
Gerald Desmond Bridge - replacement project Long Beach, California, USA #Bridge #Construction #Productivity The main structure is resolved by means of a cable-stayed bridge with a 305-m. long principal span at 61 m. over the Back Channel and two 152-m. long end spans. The project was designed with two 155-metre maximum height, single-shaft towers, 90 m. above the deck. The deck is 47 m. wide and consists of longitudinal metal beams at the ends and transversal metal beams spaced at five meters. The access viaducts to the stayed section are 900 m long on the west side and 1,155 m. long on the east side. These viaducts mostly have been executed onsite with a movable scaffolding system (MSS).
