Cantilever type reinforced concrete I-shaped composite beam and installation construction method thereof
The embodiment of the invention discloses a cantilever type reinforced concrete I-shaped composite beam. The combined beam comprises a cross beam and longitudinal beams, which are connected into the composite beam, the cross beam and the longitudinal beams are vertically mounted, first connecting assemblies used for reinforcing the joint of the cross beam and the longitudinal beams are arranged between the cross beam and the longitudinal beams, and a second connecting assembly used for reinforcing the joint of every two adjacent longitudinal beams is arranged between the two adjacent longitudinal beams. An installation construction method of the composite beam comprises the following steps: firstly, fixing plates are fixed on web plates of the longitudinal beams through bolts; then adjusting nuts are rotated to enable connecting plates to abut against longitudinal beam upper flanges or longitudinal beam lower flanges; and a nut is screwed on each positioning bolt to realize secondary fixation of the connecting plates and complete connection between the longitudinal beams; and the installation mode of the longitudinal beams and the cross beam is similar to that of the longitudinal beams, splicing of single bridge deck supporting modules can be completed by repeating the process, when the joints of the bridge deck supporting modules are stressed, force can be evenly distributed to the cross beams or the longitudinal beams through the first connecting assemblies or the second connecting assemblies, and connection is more stable.
本发明实施例公开了一种悬臂式钢混工字组合梁，包括连接成组合梁的横梁和纵梁，所述横梁与纵梁为垂直安装，且在所述横梁与纵梁之间设置有用于加固横梁与纵梁连接处的第一连接组件，在相邻两个所述纵梁之间设置有用于加固相邻两个纵梁连接处的第二连接组件，安装施工方法为：首先将通过螺栓将固定板固定于纵梁的腹板上，之后旋转调节螺母使连接板顶住纵梁上翼缘或纵梁下翼缘，并在此之后通过在定位螺栓上旋接螺母，实现对连接板的二次固定，完成纵梁与纵梁的连接，纵梁与横梁的安装方式与之相似，重复以上过程则可完成单个桥面支撑模块的拼装，其接头处在受力时，可通过第一连接组件或第二连接组件均匀的将力分摊给横梁或纵梁，连接更加稳固。
