Ripple-forming externally-wrapped corrugated steel-concrete composite beam and construction method and application thereof
Provided is a ripple-forming externally-wrapped corrugated steel-concrete composite beam. The composite beam comprises a steel framework (1) and wavy concrete (2); the steel framework (1) comprises abottom plate, a web plate, a top plate and an end plate; the beam is characterized in that the bottom plate is a corrugated bottom plate (3), the web plate is a corrugated web plate (4), and the top plate is a corrugated top plate (5); and a plurality of inverted U-shaped waves (8) are arranged on the corrugated bottom plate (3) and the corrugated top plate (5). Inverted-U-shaped wavy protrusionscan deform greatly in the loaded straightening process, so that the deformability of the composite beam under the earthquake action is improved, and the collapse resistance is enhanced; the wave starting position of the corrugated steel composite beam is covered with a non-sticky film, and the corrugated steel composite beam is not bonded with concrete locally, so that the deformation of the inverted-U-shaped wavy protrusions is not affected, and the deformability of the composite beam in an earthquake is further improved; and the bonding of two interfaces is increased through the corrugated web plate and shear-resistant channel steel, so that the situation that a steel plate and the concrete work together is guaranteed.
一种起波外包波纹钢‑混凝土组合梁，包括钢骨架(1)和波浪形混凝土(2)，钢骨架(1)包括底板、腹板、顶板和端板，其特征在于，所述底板是起波底板(3)，所述腹板是波纹腹板(4)，所述顶板是起波顶板(5)，起波底板(3)和起波顶板(5)上具有若干倒U型波(8)。倒U型波状突起处可在受荷拉直的过程中可发生大变形，增加了组合梁在地震作用下的变形能力，增强了抗倒塌能力，起波组合梁在起波处覆有不粘薄膜，使其与混凝土在局部无粘结，不影响倒U型波状突起发生变形，进一步增加了组合梁在地震中的变形能力。通过波纹腹板和抗剪槽钢增加了两个界面的粘结，保证了钢板与混凝土共同工作。
