YX66-240-720 (B) Closed profiled steel plate laying method: the total thickness h of the combined plate should not be less than 90mm, and the concrete thickness hc above the flange of the profiled steel plate should not be less than 50mm. When supported on concrete or masonry, the support length is 100mm and 75mm respectively; continuous slab or lap board supported on steel beams, the minimum support length is 75mm, when the fire rating is higher, additional longitudinal force reinforcement can be configured. In order to improve the combination effect of the composite plate, the smooth opening profiled steel plate should be arranged in the shear ***n area (evenly distributed load within the range of L / 4 at both ends of the plate) with transverse steel bars with a diameter of 6mm and a pitch of 150 to 300mm, and longitudinal rib flange The length of the weld on the board is not less than 50mm. The composite slab should be provided with distributed reinforcement mesh, and the stiffness ratio of the distributed reinforcement in both directions should not be less than 0.002. The net thickness of the profiled steel plate used in the composite plate is not less than 0.75mm, and it is better to be controlled above 1.0mm. In order to facilitate the pouring of concrete, it is required that the average groove width of the profiled steel plate is not less than 50mm. When the cylindrical head welding nail is set in the groove, the total height of the profiled steel plate (including the indentation) should not exceed 80mm.
The outer surface of YX66-240-720 (B) closed-profiled steel plate should have a protective layer to prevent atmospheric erosion during construction and use. Reinforcement requirements: In the following cases, steel bars should be arranged in the composite slabs: the negative bending moment area of &©|8203;&©|8203;the continuous slab or cantilever slab should be configured with longitudinally stressed steel bars; additional reinforcing bars should be configured around the larger concentrated load section an |
