Ultra-high performance concrete continuous bridge deck
The invention relates to the technical field of engineering, and discloses an ultra-high performance concrete continuous bridge deck which is arranged between two main beams, each main beam comprises hot-rolled section steel, end cross beams and a common concrete bridge deck, the end cross beams are arranged at the ends of the hot-rolled section steel, and the common concrete bridge deck is arranged on flange plates of the hot-rolled section steel; the ultra-high performance concrete continuous bridge deck slab comprises two first inclined planes, two second inclined planes and at least two connecting pieces, one first inclined plane is connected with one common concrete bridge deck slab, one second inclined plane is connected with one end cross beam, and the connecting pieces are connected with the common concrete bridge deck slab. And at least one connecting piece is connected with one hot-rolled section steel. The first inclined planes are connected with the common concrete bridge deck, the second inclined planes are connected with the end cross beams, and the connecting pieces are connected with the hot-rolled section steel, so that generation of plastic hinges is reduced, effective transmission of bending moment loads between two hole structures is achieved, and the crack resistance of the bridge deck continuous structure is improved.
本发明涉及工程技术领域，公开了一种超高性能混凝土连续桥面板，设置在两个主梁之间，主梁包括热轧型钢、端部横梁和普通混凝土桥面板，端部横梁设置在热轧型钢的端部，普通混凝土桥面板设置在热轧型钢的翼缘板上；超高性能混凝土连续桥面板包括第一斜面、第二斜面和连接件，第一斜面设置两个，一个第一斜面和一个普通混凝土桥面板连接，第二斜面设置两个，一个第二斜面和一个端部横梁连接，连接件设置至少两个，至少一个连接件和一个热轧型钢连接。本发明通过第一斜面和普通混凝土桥面板连接、第二斜面和端部横梁连接、连接件和热轧型钢连接，降低了塑性铰的产生，实现了两孔结构之间弯矩荷载的有效传递，提高了桥面板连续构造抗裂性能。
