TECHNICAL FEATURES
QBLOCK® is a prefabricated concrete element in the shape of a parallelepiped with variable length and square or rectangular cross section. On the base and top surfaces there are, respectively negative and positive, truncated pyramids (diamonds) which allow a precise and fast coupling of the blocks, as well as counteracting their mutual sliding.
The concrete of which it is made has C32/40 resistance class and XC4 exposure class however, upon request, it can be produced with increased resistance class, different exposure class and with high sulphate resistance (ARS) cements, light structural aggregates, MPS aggregates certified for “LEED” credits.
QBLOCK® is not reinforced as it is not subjected to tensile or bending forces, thus acquiring very high durability and fire resistance (Euroclass A1).
Technical construction measures
The support surface of the elements must be regular and flat so as to guarantee the perfect positioning of the blocks and loads.
Foundations are not necessary, however we recommend a leveling cleaning jet, preferably reinforced, so as to absorb any subsidence of the ground if the bearing capacity is not uniform or sufficient.
QBLOCK® must be laid in staggered rows so that it can keep each single block linked, avoiding creating independent columns, but rather a monolithic structure.
Movement
Movement is possible by lifting using 2.5 ton galvanized hardened steel nails and special hooks or more simply thanks to fork pockets located at the base of the block itself.
Products and services
QBLOCK® in addition to the supply of individual blocks, can provide actual assembly kits, integrated design services, static calculations, technical assistance on site transport and construction of turnkey structures.
Please note that the creation of structures using blocks is the result of a study carried out by qualified technicians appointed by the client, therefore the indications contained herein are to be understood exclusively as application examples.
QBLOCK® considers itself relieved of any responsibility related to improper use.
The supervision of a specialized technician is always recommended.
