Semi-closed and semi-open stiffening rib and stiffening plate
The invention relates to the field of stiffening plates, discloses a semi-closed and semi-open stiffening rib and a stiffening plate comprising the stiffening rib, and solves the problems that in an existing stiffening plate, an open rib is poor in torsion resistance and flexural rigidity, and a closed rib is large in welding difficulty, prone to fatigue cracking and the like. According to the technical scheme, the reinforcing rib is characterized by comprising a web plate (1) and a flange part (2), the reinforcing rib is formed by forming a steel plate, and the web plate (1) and the flange part (2) are integrally connected; the flange part (2) is tubular and is defined by forming a steel plate at the lower part of the web plate (1), the flange part (2) is provided with a tail end (20) close to the web plate (1), and the distance between the tail end (20) and the web plate (1) is 0-15mm. The upper portion adopts the open section, the connection advantage of the open rib is reserved, the lower steel plate is bent to form the flange portion capable of being naturally closed, the section of the lower edge of the rib is increased, and meanwhile the torsion resistance and the bending resistance of the stiffening rib are greatly improved through small deformation energy absorption of the lower section.
本申请涉及加劲板领域，公开了一种半闭口半开口的加劲肋及一种包含该加劲肋的加劲板，解决了现有加劲板中开口肋抗扭、抗弯刚度差，闭口肋焊接难度大、易疲劳开裂等问题。其技术方案要点是包括腹板(1)和翼缘部(2)，所述加劲肋由一张钢板成型而成，所述腹板(1)和翼缘部(2)一体相连；所述翼缘部(2)为管状，由腹板(1)下部的钢板成型所围成，所述翼缘部(2)具有与腹板(1)靠拢的尾端(20)，尾端(20)与腹板(1)的距离为0～15mm。通过上部采用开口截面，保留了开口肋的连接优势，下部钢板折弯形成能够自然闭合的翼缘部，不仅增大肋下缘截面，同时通过下部截面微小变形吸能，大幅提高加劲肋抗扭、抗弯性能。
