Fabricated cold-formed steel-UHPC waffle plate composite beam
The invention provides a fabricated cold-formed steel-UHPC waffle plate composite beam. The fabricated cold-formed steel-UHPC waffle plate composite beam comprises UHPC waffle plates, cold-formed steel beams and C-shaped connecting pieces. A first notch is formed in the UHPC waffle plate in the length direction of the UHPC waffle plate; a UHPC waffle plate is arranged on an upper flange steel plate of the cold-bent steel beam, a first connecting hole is formed in the upper flange steel plate in the length direction of the upper flange steel plate, a first notch in the UHPC waffle plate corresponds to the first connecting hole in the upper flange steel plate in position, and a cast-in-place groove is formed between the inner surface of the first notch and the top face of the upper flange steel plate. The C-shaped connecting piece comprises a C-shaped connecting plate and a bolt connecting piece, a second connecting hole is formed in a bottom plate of the C-shaped connecting plate, and the bolt connecting piece is fixedly connected with the upper flange steel plate through the corresponding second connecting hole and the first connecting hole; a through hole is formed in a top plate of the C-shaped connecting piece, a foam strip is fixedly arranged on the bottom surface of the top plate, and a filling material is arranged in a cavity of the cast-in-place groove below the top plate. The stress performance of the joint of the composite beam is improved, and the construction procedures are reduced.
本发明提供了一种装配式冷弯型钢‑UHPC华夫板组合梁，其包括UHPC华夫板、冷弯型钢梁和C型连接件；UHPC华夫板沿其长度方向开设有第一槽口；冷弯型钢梁的上翼缘钢板上设有UHPC华夫板，上翼缘钢板沿其长度方向开设有第一连接孔，UHPC华夫板上的第一槽口与上翼缘钢板上的第一连接孔位置相对应，第一槽口的内表面与上翼缘钢板的顶面之间形成现浇槽；C型连接件包括C型连接板和螺栓连接件，C型连接板的底板上开设有第二连接孔，螺栓连接件通过相应的第二连接孔和第一连接孔与上翼缘钢板固定相连；C型连接件的顶板上开设有通孔，顶板的底面固定设有泡沫条，位于顶板下方的现浇槽空腔中设有填充材料。本发明提高了组合梁连接处的受力性能，减少了其施工工序。
