Corrugated steel plate reinforced orthogonal laminated wood composite floor slab and manufacturing method
The invention relates to a corrugated steel plate reinforced orthogonal laminated wood composite floor slab. The corrugated steel plate reinforced orthogonal laminated wood composite floor slab comprises orthogonal laminated wood, self-tapping screws and a corrugated steel plate; the corrugated steel plate is attached to the orthogonal laminated wood, so that the length defense line where the wave crest of the corrugated steel plate is located is in the rift grain direction of the orthogonal laminated wood; and the self-tapping screws perpendicularly penetrate into the corrugated steel plate and the orthogonal laminated wood from the wave trough of the orthogonal laminated wood. According to the corrugated steel plate reinforced orthogonal laminated wood composite floor slab, the good flexural rigidity of the corrugated steel plate can be fully utilized to improve the overall stability of the floor slab, and thus the vibration comfort degree of the composite floor slab is improved. Meanwhile, part of the steel plate in the corrugated steel plate is far away from the section neutral axis and can yield first under the action of bending moment to generate plastic deformation, and thus brittle failure of the orthogonal laminated wood due to tensile fracture of wood is avoided. In addition, the action of the self-tapping screws is similar to that of stirrups in a reinforced concrete structure, and the rolling shear bearing capacity of the floor slab can be improved to a certain extent.
本发明涉及一种波纹钢板加强的正交胶合木组合楼板，包括正交胶合木、自攻螺丝、波纹钢板；所述波纹钢板与正交胶合木贴合，使波纹钢板的波峰所在的长度防线沿正交胶合木的顺纹方向；所述自攻螺丝自所述正交胶合木的波谷处垂直穿入所述波纹钢板和正交胶合木。本发明可充分利用波纹钢板良好的抗弯刚度提升楼板的整体稳定性，从而提升组合楼板的振动舒适度。同时，波纹钢板中部分钢板距离截面中和轴较远，在弯矩作用下可率先屈服，产生塑性变形，从而避免正交胶合木由于木材受拉断裂引起的脆性破坏。此外，自攻螺丝的作用类似于钢筋混凝土结构中箍筋的作用，能够在一定程度上提升楼板的滚剪承载力。
