Sawtooth-shaped box-type steel-concrete composite beam
The invention discloses a sawtooth-shaped box type steel-concrete composite beam which comprises a steel box beam bottom plate, two steel box beam side webs, a steel box beam middle web, an inverted trapezoidal connecting piece, a regular trapezoidal opening connecting piece, a ribbed penetrating reinforcing steel bar and a concrete plate, and the steel box beam is formed by welding the two steel box beam side webs and the two steel box beam middle webs on the steel box beam bottom plate. And the top of the web is cut to form an inverted trapezoidal connecting piece and a regular trapezoidal perforated connecting piece, and finally the ribbed penetrating reinforcing steel bars penetrate through the holes to be placed. The zigzag box-type steel-concrete composite beam is simple in structure, the zigzag box-type steel-concrete composite beam structure form is provided, the zigzag box-type steel-concrete composite beam can be used on a large-span bridge, the adopted zigzag connecting pieces can well ensure that the box beam and the concrete slab work cooperatively under stress, and the zigzag box-type steel-concrete composite beam has the advantages of being high in bearing capacity and good in ductility.
本发明公开了一种锯齿状箱型钢混组合梁，包括钢箱梁底板、钢箱梁边腹板、钢箱梁中腹板、倒梯形连接件、正梯形开孔连接件、带肋贯穿钢筋和混凝土板，通过在钢箱梁底板上焊接两块钢箱梁边腹板和钢箱梁中腹板形成钢箱梁，在腹板顶部进行切割，形成倒梯形连接件和正梯形开孔连接件，最后将带肋贯穿钢筋穿过孔内放置。本发明结构简单，提出锯齿状箱型钢混组合梁结构形式，可以用作大跨径桥梁上，采用的锯齿连接件，能够较好的保证箱梁与混凝土板协同受力工作并具有承载力高、延性好的优势。
