Description
技术领域technical field
本实用新型属于土木工程领域，涉及建筑结构加固，特别涉及一种用于钢筋混凝土梁柱节点的抗震加固装置。The utility model belongs to the field of civil engineering and relates to building structure reinforcement, in particular to an anti-seismic reinforcement device for reinforced concrete beam-column joints.
背景技术Background technique
房屋建筑和工业建筑中钢筋混凝土框架结构的梁柱节点是关键的结构部件，节点核心区抗震性能是影响钢筋混凝土结构抗震性能的关键因素。在现代抗震规范建立之前，重力荷载是建筑结构设计的主要参考标准，因而目前这些结构在抗震设防区域不能满足抗震设计要求，特别是钢筋混凝土梁柱节点由于缺乏相应的抗震构造措施，在地震力的作用下非常脆弱；而且随着抗震设计要求提高，一些参考旧抗震规范设计的钢筋混凝土梁柱节点的抗震性能往往也难以满足现有规范要求。目前还没有很有效的加固方法和技术，这成为钢筋混凝土结构加固的难点。随着地震灾害形势日趋严重，钢筋混凝土梁柱节点抗震加固新技术和新方法研发工作日趋重要和紧迫。Beam-column joints of reinforced concrete frame structures in housing and industrial buildings are key structural components, and the seismic performance of the core area of joints is a key factor affecting the seismic performance of reinforced concrete structures. Before the establishment of modern seismic codes, gravity load was the main reference standard for building structure design. Therefore, these structures cannot meet the seismic design requirements in seismic fortification areas, especially the reinforced concrete beam-column joints due to the lack of corresponding seismic structural measures. It is very fragile under the action of earthquake resistance; and with the improvement of seismic design requirements, the seismic performance of some reinforced concrete beam-column joints designed with reference to the old seismic codes is often difficult to meet the requirements of the existing codes. At present, there is no very effective reinforcement method and technology, which has become a difficulty in the reinforcement of reinforced concrete structures. As the earthquake disaster situation is becoming more and more serious, the research and development of new technologies and methods for seismic strengthening of reinforced concrete beam-column joints is becoming more and more important and urgent.
由于施工不方便，很难在钢筋混凝土梁柱节点核心区周围增加外加箍筋或箍板，目前常用方法是在钢筋混凝土梁柱节点核心区包裹碳纤维布来进行钢筋混凝土梁柱节点核心区抗震加固，但是这种加固方法仅仅是对钢筋混凝土梁柱节点混凝土产生被动约束作用，而且这种被动约束作用并不是非常显著，同时碳纤维布加固后的混凝土逐渐容易发生脆性破坏，所以这种加固方法仍有较大局限性。目前，国内外，关于钢筋混凝土梁柱节点核心区加固没有完全成熟技术，梁柱节点抗震加固成为钢筋混凝土框架结构抗震加固的难题。Due to the inconvenience of construction, it is difficult to add additional stirrups or hoops around the core area of reinforced concrete beam-column joints. At present, the common method is to wrap carbon fiber cloth in the core area of reinforced concrete beam-column joints to carry out seismic reinforcement of the core area of reinforced concrete beam-column joints , but this reinforcement method only produces passive restraint on reinforced concrete beam-column joint concrete, and this passive restraint effect is not very significant. There are major limitations. At present, at home and abroad, there is no fully mature technology for strengthening the core area of reinforced concrete beam-column joints, and the seismic strengthening of beam-column joints has become a difficult problem in the seismic strengthening of reinforced concrete frame structures.
