UHPC reinforced reinforced concrete shear wall structure and construction method thereof

HU HONGSONG / HU YUANCHANG / HU YUNYUN

The invention provides a UHPC (Ultra High Performance Concrete) reinforced concrete shear wall structure, which relates to the field of building structures and comprises a reinforced concrete shear wall main body, a UHPC encircling sleeve, a connecting piece and a steel plate, the UHPC enclosure wraps the periphery of the reinforced concrete shear wall body, the steel plate is arranged on the edge surface of the UHPC enclosure, one end of the connecting piece is arranged on the outer side of the steel plate, and the other end of the connecting piece penetrates through the inner side of the steel plate to connect the reinforced concrete shear wall body and the UHPC enclosure. According to the structure, the performance advantages of UHPC materials and steel are fully combined, and the UHPC materials and the steel are combined into a whole which is stressed together, so that the structure can play the advantages of the mechanical property of the UHPC, the appearance of'fat beams and fat columns' of a concrete structure reinforced by a traditional section increasing method is improved, the influence on the dead weight and rigidity of the structure is smaller, and meanwhile the durability of the structure is improved. The invention further provides a construction method for reinforcing the reinforced concrete shear wall structure based on the UHPC.

本发明提供一种UHPC加固钢筋混凝土剪力墙结构，涉及建筑结构领域，包括钢筋混凝土剪力墙主体、UHPC围套、连接件和钢板；UHPC围套包裹在钢筋混凝土剪力墙主体的外围，钢板置于UHPC围套的边缘表面上，连接件一端置于钢板外侧，另一端穿过钢板内侧以连接钢筋混凝土剪力墙主体和UHPC围套。本结构充分结合了UHPC材料和钢材的性能优势，并将其组成共同受力的整体，使得该结构能够发挥UHPC力学性能的优势，改善传统增大截面法加固混凝土结构“肥梁胖柱”的面貌，对结构自重、刚度影响更小，同时改善了结构的耐久性能。本申请另提供一种基于UHPC加固钢筋混凝土剪力墙结构的施工方法。
