The fire-resistance tests of the brick curtain walls involving the BAUT system were conducted in Saint Petersburg, Russia. The tests aimed to determine the fire resistance class of the BAUT system.
A fragment of a three-layer wall was constructed in a laboratory setting as a representative model of a multi-storey building under construction at that time in Saint Petersburg.
The fragment under examination was made using the elements of the BAUT system: brackets (with an anchoring depth of 300 mm), reinforcement, connectors and hooks. The wall through the first-storey window was exposed to open fire for 45 minutes. No changes in the BAUT system were detected. After the test, the wall was dismantled and the condition of all components was evaluated. None of the components sustained any damage.
The test results demonstrated that the BAUT system meets the strictest fire-resistance requirements (fire resistance class K0 according to the applicable standard).
DESIGN OF A PROTOTYPE OF PREFABRICATED BRICK VENEER LAYER AND ANALYSIS OF ITS BEHAVIOUR
Ceramic bricks are most frequently used for arranging the cladding layer of external layered masonry walls. The recent tendency
has focused on a thinner cladding layer. Masonry lintels are used for making openings in the cladding layer. The article presents
the results of experimental investigation in masonry lintels of 85 mm and 55 mm in width and 2 m long span. The experimentally
established and calculated according to EC6 recommendations masonry lintels bearing load capacity has been compared.
Tested brick lintel of hollow ceramic bricks (opening up to 2,09m wide) shows that lintel bearing capacity and the formation of cracks time margin is 3 times lower than calculated value.
The project evaluates the influence of the brackets on the heat transfer by point thermal bridges.
THE AIM OF TEST
Analysis of support brackets attached to the ceramic block chemical anchors bearing capacity.
