Post tension slab on grade
Key benefits of post-tensioned slabs-on-grade
Besides some of the same economic benefits as mentioned with suspended slab applications, there are some additional special aspects worth mentioning here:
01.
large joint-free slab areas (free of saw cuts)
02.
reduced risk of cracking and crack formation
03.
enhanced water tightness/resistance properties
04.
reduced on-going maintenance costs and lower downtime in facilities
05.
superior performance in weak ground conditions
06.
less sub-base preparation and reduced excavation needed for thinner slabs
07.
Increased load-carrying capacity of the floor
08.
flatter slabs with better deflection control, particularly suited to very high narrow aisle shelving systems
09.
superior performance in weak ground conditions
10.
reduced construction materials and lower construction costs
11.
faster construction time
12.
more durable floors that are significantly better at resisting wear and abrasion.
- Technical assistance in all the phases of the project from the design to the final execution.
- A large range of live end and dead end anchorages and couplers, being always ready for any development or change according to the specifics needs of the project.
- The designed system was successfully tested according to the new European standard ETAG-013 for post-tensioning systems.
- The possibility to use metallic and PE/PP ducts depending on the project specifications.
- Automatic and lightweight stressing equipment.
- Study of alternative design or construction method as an improvement for the optimum solution for every project.
Post tension elevated slabs.
SPAN TECH use
Post-tensioning system unbounded or bonded applications with 1, 2 or 4 strands. The system has been optimized to feature lighter anchorages and offer designers the smallest available tendon center spacing and concrete edge distance for stressing at the very low concrete strength. It also includes features which accelerate installation and thus reduce material and labor costs.
01.
Available in either 1, 2, 3 or 4 strand anchorage configurations.
02.
Compact lightweight anchorages optimized for either 12.9mm or 15.7mm diameter, 1,860MPa strand
03.
Advanced proprietary monolithic anchorage for very small tendon center spacing’s and concrete edge distances
04.
Even smaller spacings are achievable when local anti-bursting reinforcement (either stirrups or helix cage) is added, by using an innovative support chair to centralize the reinforcement
05.
Monolithic coupling anchorage with an integrated, preinstalled wedge
06.
Superior corrosion protection ensured with a threaded transition pipe
07.
In unbonded applications, greased/waxed and individually HDPE sheathed monostands are used
08.
In bonded applications, flat corrugated galvanized steel or plastic ducts are filled with a high performance grout
09.
Restress able & exchangeable tendons perfectly suited to long-term inspection and maintenance
10.
reduced construction materials and lower construction costs
11.
faster construction time
12.
more durable floors that are significantly better at resisting wear and abrasion.
Unbonded monostand systems
SPAN TECH can offer unbonded mono strand systems (greased and PE-coated stand). unbonded mono-strand system uses 0,6” and 0,62” diameter strand of 1860 MPa capacity.
Multi-strand bonded systems
Multi-strand bonded systems with either round or flat corrugated duct is also provided as an alternative for the construction of slabs in buildings when this type of system is required.
Post tension bridge girders
Post-Tensioning (PT) is a dynamic technology that allows for the cost-effective construction of high-quality bridges. PT is adaptable in that it can be implemented in a wide variety of conditions and lengths. Post-tensioned bridges have a high degree of intrinsic durability, can be constructed relatively swiftly, are at a lesser risk of cracking, have lesser structural depth, and feature low maintenance costs. Additionally, these bridges can be built without touching the geography below- permitting longer spans (~300 ft.), and shallower girders. Better ductility, seismic performance, and aesthetics are common benefits gained from utilizing post-tensioning.
SPAN TECH post-tensioning propose a gear range of anchorages, accessories and the necessary equipment to respond to the technical requirements for the construction of bridges and other structures. Which international approved brands with ETA & PTI approvals
Structural design
We have extensive experience in the design of structural engineering projects collaborating with architects, building owners and contractors. Our services cover all stages of the development process from conceptual and feasibility planning to design detail and construction details. We work in most sectors including commercial, residential, retail, industrial, leisure, education and health.
We strive for the perfect balance between demand, function, sustainability, constructability, schedule and budget.
Our experienced team of engineers combines an in-depth understanding of the design of structures with the use of modern analytical tools, and the latest 3D structural modelling packages delivering projects in both Revit and Tekla software.
We are passionate about engineering, and produce buildings to the highest design quality. We work proactively with both clients and professionals to design solutions that exceed the expectations of the building users and owners, and always seek to delight our clients.
