摘要
工业建筑结构改造加固工程中常需大幅度提高梁的承载力,普通粘钢板加固方法应用受到限制,而通过螺栓锚固H型钢使其与混凝土梁共同工作来扩大结构受力截面可满足这一要求。以某具体加固工程为例介绍了H型钢加固混凝土梁技术的设计、构造和施工工艺。
The bearing capacity of the beam often needs to significantly improve in the reform of industrial buildings. The technology of strengthening with externally bonded steel plate is very limited. The co-action of anchored H-section steei and concrete beams to enlarge forced sections of structure can meet the said requirement. The design and construction method of H-section steel reinforced concrete beam technology are clarified with a specific strengthened proiect.
