The invention discloses a first hole method orthotropic plate unit and a manufacturing method thereof, and relates to the technical field of bridge construction. The manufacturing method of the first-hole method orthotropic plate unit comprises the following steps: forming holes in a main plate to form a template with holes; holes are formed in the plane plate material to form a flat plate with holes, the flat plate with the holes is bent to form a U-shaped rib, and the U-shaped rib comprises a flat plate part and two inclined plate parts; a plasma cutting machine is used for cutting the avoiding holes in the plane plate material to manufacture a formed cross beam; a plurality of U-shaped ribs and forming cross beams are assembled on a main plate with holes in a criss-cross mode, and the U-shaped ribs, the forming cross beams and the main plate with the holes are connected through bolts. The connecting holes are firstly formed in the plane plate material by using the hole forming template, the hole forming efficiency is high by adopting a first hole method, then the U-shaped rib is formed by bending, and then the U-shaped rib, the forming cross beam and the main plate with the holes are connected and fixed through the bolts, so that the mounting is simple, cracking caused by stress concentration can be effectively avoided, and the connecting holes can be detached and replaced even if the connecting holes are cracked.
本发明公开一种先孔法正交异性板单元及其制作方法，涉及桥梁建造技术领域。所述先孔法正交异性板单元的制作方法包括以下步骤，在主板上制孔形成带孔模板；在平面板料上制孔形成带孔平板，将带孔平板折弯形成U型肋，U型肋包括平板部和两个斜板部；使用等离子切割机在平面板料上切割避让孔制成成型横梁；将多个U型肋以及成型横梁按照纵横交错的方式组装到带孔主板上，其中U型肋、成型横梁和带孔主板之间均采用螺栓连接。本发明通过使用制孔模板先在平面板料上制成连接孔，采用先孔法制孔，制孔效率高，然后折弯形成U型肋，然后将U型肋、成型横梁和带孔主板通过螺栓连接固定，安装简单且可有效避免应力集中导致开裂，即使开裂也可拆卸更换。
