Method for improving bending strength of existing reinforced concrete beam
The invention provides a method for improving the bending strength of an existing reinforced concrete beam, and relates to the technical field of civil engineering structure reinforcement. The method comprises the following steps that 1, UHPC composite boards are manufactured; and 2, the UHPC composite boards are installed at the bottom of the reinforced concrete beam. According to the method for improving the bending strength of the existing reinforced concrete beam, the flexural capacity and durability of the reinforced concrete beam are improved, meanwhile, the construction period is shortened, interference to the surrounding environment is reduced, the later maintenance cost is reduced, and the beneficial technical effects are achieved.
本发明提供了一种提升既有钢筋混凝土梁抗弯强度的方法，涉及土木工程结构加固技术领域，本发明的方法包括以下步骤：步骤1、制作UHPC复合板；步骤2、在钢筋混凝土梁底部安装所述UHPC复合板。本发明在提高了钢筋混凝土梁的抗弯承载力和耐久性的同时，缩短了施工周期、减少了对周围环境的干扰，降低了后期的维护成本，具有有益的技术效果。
