Composite beam made of steel, common concrete and ultra-high performance concrete and construction method
The invention discloses a composite beam made of steel, common concrete and ultra-high performance concrete and a construction method. The composite beam comprises a steel beam and a composite plate arranged on the steel beam. The composite board comprises prefabricated common concrete slabs and an ultra-high performance concrete board layer. The part, connected with the composite board, of each steel beam comprises a top surface, wherein the top surface is parallel to the horizontal plane; protruding parts extending downwards are arranged at the positions, corresponding to all the top surfaces, of the lower face of the ultra-high performance concrete board layer, wherein the width of the protruding part is smaller than that of the corresponding top surface, and the length is matched withthe corresponding top surface; the prefabricated common concrete slabs are arranged between every two protruding parts; and the lower faces of all the protruding parts are flush with the lower faces of all the prefabricated common concrete slabs. During construction, the method comprises the steps: firstly, preparing the prefabricated common concrete slabs, and erecting the steel beams; then, laying the prefabricated common concrete slabs, and installing a shear-resistant connector; and finally, pouring the ultra-high performance concrete board layer. The problem that concrete in the hogging moment area of the composite beam is prone to cracking is solved, and the method is particularly suitable for steel-concrete composite beams.
本发明公开了钢材、普通混凝土和超高性能混凝土的组合梁及施工方法，包括钢梁，以及设置钢梁上的复合板；复合板包括预制普通混凝土板和超高性能混凝土板层；每一钢梁与复合板连接的部分均包括一个顶面；顶面与水平面平行；超高性能混凝土板层下面对应每一顶面均设有向下延伸的凸出部；突出部的宽度小于相应的顶面，长度与相应的顶面相配；每两个凸出部之间均设有预制普通混凝土板；所有凸出部的下面和所有预制普通混凝土板的下面齐平。施工时，首先，制作预制普通混凝土板并架设钢梁；然后铺设预制普通混凝土板，安装抗剪力连接器；最后浇筑超高性能混凝土板层。本发明解决了组合梁负弯矩区混凝土易开裂的问题，尤其适用于钢混凝土组合梁。
