Steel truss web combined beam for highway-railway combined construction
The invention discloses a steel truss web combined beam for highway-railway combined construction, which comprises an upper-layer concrete slab, a lower-layer concrete slab and a steel truss web, eachlayer of concrete slab is mainly composed of a concrete bridge deck slab, a concrete main longitudinal beam, a concrete secondary longitudinal beam and a concrete cross beam set; the concrete main longitudinal beams, the concrete secondary longitudinal beams and the concrete cross beam sets are all arranged at the bottom of the concrete bridge deck slab; concrete secondary longitudinal beams arearranged between the two concrete main longitudinal beams; the longitudinal directions of the concrete secondary longitudinal beams are consistent with the longitudinal directions of the concrete mainlongitudinal beams; the concrete cross beam set is located between the two concrete main longitudinal beams and comprises a plurality of concrete cross beams; and the longitudinal direction of each concrete cross beam is perpendicular to the longitudinal direction of the corresponding concrete main longitudinal beam; the steel truss web is mainly composed of a steel web member, a lower-layer concrete joint plate and an upper-layer concrete joint plate; and the steel web members are fixedly connected with the upper-layer concrete joint plates and the lower-layer concrete joint plates respectively. The steel truss web combined beam has the advantages of being high in rigidity, good in stability, low in driving noise, good in comfort, low in manufacturing cost, convenient to maintain and repair and the like.
本发明公开了一种用于公铁合建的钢桁腹结合梁，包括上、下两层混凝土板和钢桁腹，每层混凝土板主要由混凝土桥面板、混凝土主纵梁、混凝土次纵梁和混凝土横梁组构成，混凝土主纵梁、混凝土次纵梁和混凝土横梁组均设在混凝土桥面板底部，两根混凝土主纵梁之间布置混凝土次纵梁，混凝土次纵梁的纵向均与混凝土主纵梁的纵向一致，混凝土横梁组位于两根混凝土主纵梁之间且包括多根混凝土横梁，每根混凝土横梁的纵向均与混凝土主纵梁的纵向垂直；钢桁腹主要由钢腹杆、下层混凝土接头板和上层混凝土接头板组成；钢腹杆与上、下层的混凝土接头板分别固接。本发明可公铁两用，具有刚度大、稳定性好、行车噪声低、舒适性好、造价低、养护维修方便等优点。
