The steel box girder comprises a box girder assembly, the box girder assembly comprises a steel box, rib plates, I-shaped steel and a mounting support, the rib plates are arranged on the two sides of the inner wall of the steel box, the mounting support is arranged at the bottom of the inner wall of the steel box, and the I-shaped steel is arranged on the steel box. And the I-shaped steel is connected with the steel box through the mounting bracket. The steel box is arranged to replace traditional wood formwork construction, H-shaped steel in the steel box can be placed on the ground, it is avoided that a steel platform is erected for high-altitude operation, the construction difficulty is lowered, the construction efficiency is improved, and the construction safety is improved; due to the existence of the H-shaped steel and the ribbed side walls, the connection strength of the concrete and the section steel is improved, and the defect that the tensile capacity of the concrete serving as a main compression component is not high is overcome.
本发明公开了一种用于高空单梁的钢箱梁及其吊装设备及其施工方法,其包括箱梁组件,所述箱梁组件包括钢箱、肋板、工字钢和安装支架,所述肋板设置于钢箱内壁两侧,所述安装支架设置于钢箱内壁底部,所述工字钢通过安装支架与钢箱连接。本发明通过设置钢箱代替传统的木模板施工,钢箱内H型钢放置作业可以在地面操作,避免搭设钢平台进行高空作业,降低了施工难度、提高施工效率、增加施工安全性;H型钢与带肋侧壁的存在增加了混凝土与型钢的联结强度,弥补了混凝土作为主要受压构件其抗拉能力不强的缺点。
