Corrugated steel web combined channel beam and construction method thereof
The invention discloses a corrugated steel web combined channel beam and a construction method thereof, the corrugated steel web combined channel beam comprises a corrugated steel web I-shaped beam, an upper flange concrete plate and a concrete bottom plate, an outer wrapping steel plate is arranged on the outer side of the upper flange concrete plate and/or the concrete bottom plate, and a steel support is arranged between the outer wrapping steel plate of the concrete bottom plate and the corrugated steel web I-shaped beam. The rigidity of the channel beam is improved through the outer wrapping steel plate, the anti-bending bearing capacity and torsional rigidity of the beam body are improved, the corrugated steel web I-shaped beam is directly erected on the outer wrapping steel plate through the steel support, and integrated erection of the concrete bottom plate, the corrugated steel web I-shaped beam and the upper flange concrete plate is formed; simultaneous pouring of first-stage concrete and second-stage concrete of the beam body is achieved, and the construction period is shortened; in addition, the outer wrapping steel plate can be used as a formwork and does not need to be dismantled after the beam body is poured, and construction procedures are reduced. And the protective layer can also be used as a protective layer of the beam body, so that air and corrosive media are prevented from invading after the beam body cracks, and the use durability of the beam body is prolonged.
本发明公开了一种波形钢腹板组合槽形梁及其施工方法，包括波形钢腹板工形梁、上翼缘混凝土板和混凝土底板，上翼缘混凝土板和/或混凝土底板外侧设有外包钢板，混凝土底板的外包钢板和波形钢腹板工形梁之间设置钢支撑。本发明通过外包钢板提升了槽形梁的刚度，增大了梁体的抗弯承载能力和抗扭刚度，且波形钢腹板工形梁通过钢支撑直接架设在外包钢板上，形成混凝土底板、波形钢腹板工形梁和上翼缘混凝土板的一体化架设，实现梁体一期混凝土和二期混凝土的同时浇筑，缩短了施工周期；此外，外包钢板可充当模板使用，在梁体浇筑后不需拆除，缩减了施工工序；还可作为梁体的保护层，防止在梁体裂缝出现后，空气和腐蚀介质的侵入，延长了梁体的使用耐久性。
