MTR® T BEAM By METAL.RI
Structural steel beam, column, and section
The beams are easy to assemble and they achieve good performance in a single move: from the storage area directly on the wooden formwork or on the predalle slabs.
The solution that replaces the traditional concrete steel with improved adhesion property to assembly on site: a lightweight prefabricated construction system that can be combined with traditional building systems. It is the ideal solution for residential buildings.
The MTR® T Beam is not self-supporting and must be placed on a formwork or on the slab of predalle floors. The MTR® T Beam can be used to make slim floor beams where it is not possible for the ordinary reinforced concrete.
The MTR®T Beam has the CE Marking according to the UNI EN 1090-1. It consists of one or more lattice girders made of metallic steel, which are assembled together. The distance between axes is from 15 to 25 cm : each girder consists of two top chords and two bottom chords; these are linked by a central web possibly provided with additional diagonal end , to be completed on site by casting it with collaborating concrete .
The MTR® T beams can be combined with any type of floor and vertical structure since standard dimensions do not govern their production. They can be used in the building sectors where the self-supporting feature is not indispensable.
The advantages of the MTR® T Beams
● Reduction of floor building times of 50%
● Reduction of the number of columns and their sections
● Reduction of height and width beam sections
● Reduction of column buckling
● Reduction of the concrete used for beams
● Fire resistance without extra costs and additional work
Maximum design freedom
● The buildings made of MTR® T Beams have floors with completely flat intrados.
● Mixed structure with lots of advantages against the traditional reinforced concrete buildings
● Easy to handle and certainty about the quantity of reinforcement steel used.
Technical specification
● Steel Structure: it is made of structure steel according to the EN ISO 10025-2 standard.
● Concrete finishing: class C25/30, unless otherwise indicated.
● Welding: continuous wire welding with shielding gas (Process UNI EN ISO 4063-135) according to the NTC of 2008.
● Normative References: paragraph no. 4.2 of the NTC of 2008 and Eurocodes 2 and 4. For the structures built in seismic zones, we refer to the chapter no. 7 of the NTC 2008 and to the Eurocode 8.
● Engineering Design Process: our engineers follow the calculation procedure of the Software MTR® according to the existing law.
● Post-Fire mechanical properties (R): it depends on the bottom concrete cover or on the thickness of the predalle slabs where it lays on
● Base: none
