Tough steel mixed bridge floor
The invention discloses a tough steel mixed bridge floor, which mainly relates to the technical field of road and bridge construction equipment, and comprises a corrugated steel bottom plate, a concrete layer and a shearing force connecting piece, symmetrical arc-shaped openings are equidistantly formed in the upper part of the shearing force connecting piece, elliptical holes are equidistantly formed in the lower part of the shearing force connecting piece, and transverse steel bars are arranged on the symmetrical arc-shaped openings in a penetrating manner; the longitudinal steel bars are distributed on the upper sides and the lower sides of the transverse steel bars at equal intervals on the oval holes of the V-shaped steel bars, the studs are arranged on the corrugated steel bottom plate, the transverse steel bars can improve the shear resistance and the fatigue resistance of the combined bridge deck slab, and it is guaranteed that the combined bridge deck slab has the higher shear resistance and the good fatigue resistance. The V-shaped steel bars improve the reinforcement ratio, concrete cracking is effectively avoided, anchoring of the corrugated steel bottom plate and the concrete layer can be enhanced, large shearing force can be borne, the studs play a good supporting role and anti-shearing and anti-lifting roles, the rigidity of a bridge deck is improved, the load of the concrete layer is borne, and fatigue stress of key parts of the steel bridge deck is greatly reduced.
本发明公开了一种韧性钢混合桥面，主要涉及路桥施工设备技术领域，包括波形钢底板、混凝土层、剪力连接件，在剪力连接件的上部等距设置对称的弧形开口、下部等距设置椭圆开孔，横向钢筋贯穿设置在对称的弧形开口上，V形钢筋椭圆开孔上，纵向钢筋等距分布在横向钢筋上下两侧，在波形钢底板上设有栓钉，横向钢筋能够提高组合桥面板的抗剪能力和抗疲劳性能，保证组合桥面板具有更高的抗剪能力和较好的抗疲劳性能。V形钢筋提高配筋率，有效避免了混凝土开裂，可加强波形钢底板与混凝土层的锚固，又可承受较大的剪力，栓钉起到良好的支撑作用和抗剪切及抗掀起的作用，增加桥面的刚度，来承担混凝土层荷载，大幅度降低钢桥面板关键部位的疲劳应力。
