Fabricated composite beam construction method
The invention discloses a fabricated composite beam construction method, and relates to the technical field of building construction. Comprising the steps that firstly, a prefabricated concrete bridge deck is manufactured, and concave-convex shear force grooves, grouting holes and grout emitting holes are formed in haunched positions of the prefabricated concrete bridge deck; 2, machining and assembling the steel beam, and welding group nail connecting pieces on the upper flange of the steel beam; thirdly, the prefabricated concrete bridge deck is installed, long welding studs are arranged in the grouting holes and the grout emitting holes in a sleeved mode, and short welding studs are placed in convex key teeth of the concave-convex shear grooves; fourthly, concave-convex shear grooves are filled; and fifthly, transverse and longitudinal wet joints between the prefabricated concrete bridge deck slabs are poured, and after the cement-based filler in the concave-convex shear grooves is preliminarily hardened, steel bars are bound in the transverse and longitudinal wet joints between the prefabricated concrete bridge deck slabs, and high-strength concrete with fibers is poured. The method can avoid position conflicts of welding studs and steel bars during installation of the prefabricated concrete bridge deck and weakening of the section caused by opening of the prefabricated concrete bridge deck.
本发明公开一种装配式组合梁施工方法，涉及建筑施工技术领域；包括步骤：步骤一、预制混凝土桥面板的制作，预制混凝土桥面板在加腋处设置凹凸剪力槽、灌浆孔和冒浆孔；步骤二、钢梁的加工和组装，在钢梁上翼缘焊接群钉连接件；步骤三、安装预制混凝土桥面板，将长焊钉套在灌浆孔和冒浆孔中，短焊钉放在凹凸剪力槽的凸键齿内；步骤四、凹凸剪力槽填充；步骤五、预制混凝土桥面板之间横向和纵向湿接缝的浇筑，待凹凸剪力槽内的水泥基填充料初步硬化之后，在预制混凝土桥面板之间的横向和纵向湿接缝内绑扎钢筋并浇筑带纤维的高强混凝土。本发明能够避免预制混凝土桥面板安装时焊钉和钢筋位置冲突以及预制混凝土桥面板开孔对于截面的削弱。
