Reinforcing method of concrete large plate girder
The invention relates to a method for reinforcing a concrete large plate beam, belongs to the technical field of industrial building concrete structure reinforcement, is mainly applied to a tapping platform structure of an iron-making blast furnace in a steel mill, and discloses a method for reinforcing a concrete large plate beam before a beam bottom is holed and a main reinforcement is cut off. The method comprises the following steps that holes are drilled in preset positions of concrete columns and beams at the two ends of the large plate beam, gusset plates are installed, the gusset plates are fixed to the concrete columns and the beams through tie bolts, steel pull rods are installed after the gusset plates are installed, the steel pull rods are connected with the gusset plates in a welded mode, and gaps between the steel pull rods and the drilled holes are filled with cement mortar. And after the steel pull rod is installed, the middle supporting rod and the tensioning device are installed at the preset position, and after all installation is completed, the tensioning device is used for tensioning the steel pull rod. According to the reinforcing method, installation is convenient, operation is easy, it can be guaranteed that the original structure and the newly-added steel pull rods are stressed together, and therefore the bearing capacity of the large plate beam before the bottom of the large plate beam is holed is achieved.
本发明涉及一种混凝土大板梁的加固方法，属于工业建筑混凝土结构加固技术领域，主要是应用在钢厂炼铁高炉出铁平台结构上，公开了一种梁底开洞、切断主筋前的混凝土大板梁加固方法，该方法包括以下步骤：在大板梁两端的混凝土柱和梁预定位置钻孔，安装节点板，节点板通过拉结螺栓固定在混凝土柱和梁上，节点板安装完后安装钢拉杆，钢拉杆通过焊接的方法与节点板连接，钢拉杆与钻孔之间的间隙用水泥砂浆填实，安装完钢拉杆后在预定位置安装中间撑杆和拉紧装置，全部安装完成后，使用拉紧装置对钢拉杆进行拉紧。本发明的加固方法安装方便、操作简单，能保证原结构与新增钢拉杆共同受力，从而达到大板梁梁底未开洞前的承载能力。
