既有砌体建筑抗震加固工业化成套施工技术

Matching Construction Technique for Seismic Reinforcement Industrialization of Existing Masonry Building

结合北京海淀区甘家口1,3,4号住宅楼等抗震加固工程试点应用,通过从基础桩锚固、预制构件加工制作、预制构件的连接方式、预制构件与原建筑的衔接以及屋顶卧梁、拉梁拉结形式,使之与外套预制墙板形成一体来约束原有砌体,最终形成科学、合理、可行、适用的既有砌体建筑工业化抗震加固加固体系综合施工技术,实现了老旧楼房通过加固改造后达到国家抗震标准,最终显著提高砌体住宅的抗震性能。

Combined with the Beijing Haidian District, Ganjiakou 1,3,4 residential buildings and other seismic strengthening project pilot applications.Through the anchorage of foundation piles, the fabrication of prefabricated components, the connection of prefabricated components, the connection of prefabricated components with the original building, and the form of roof lying beam and pull beam, And eventually form a scientific, reasonable, feasible and applicable integrated construction technology for the existing industrialized seismic strengthening and reinforcement system for masonry buildings, realizing that the old buildings meet the national seismic standards after being reinforced and improved so as to ultimately improve the seismic performance of the masonry buildings.
