Dynamic loading test:
The qualified floor board should be tested by several groups of dynamic loading tests, and the shear bond coefficient of the composite plate is obtained, and the combined capacity of the slab and concrete is tested, and the design load on the large span is obtained.
Fire resistance test:
Floor plates made of floor deck forming machine were used to test the fire resistance for 1.5 hours, 2 hours and 3 hours in the fire-resistant laboratory. At the same time, the temperature distribution on the floor was measured. The test showed whether the floor plate reached the heat insulation requirement and the resistance ability of the positive bending moment in the refractory stage.
