Construction process for reinforcing and transforming old house
The invention discloses an old house reinforcement and transformation construction process, and relates to a building construction method, in particular to an old house transformation construction method. The technology comprises the following steps that the cantilever steel structures on the periphery of an existing building wall are dismantled; a reinforced concrete outer cylinder sleeves the periphery of the outer side of the existing building wall according to the outer contour of the original building; a foundation is arranged on the reinforced concrete outer cylinder again, and the reinforced concrete outer cylinder and the existing building form a reinforced concrete cylinder-in-cylinder structure again; the newly-built reinforced concrete outer cylinder is settled, and then the existing building is connected with the newly-built reinforced concrete outer cylinder; and a high-strength shrinkage-free grouting material is poured into a gap between the existing building and the newly-built reinforced concrete outer cylinder. The problems that in old house transformation and rebuilding construction, beam columns and other bearing components are reinforced, and the transformed building structure is difficult to meet the design strength requirement are solved.
本发明公开了旧房屋加固改造施工工艺，涉及建筑施工方法，具体涉及旧房改造施工方法。所述工艺包括以下步骤：既有建筑墙体四周的悬挑钢结构拆除；按照原建筑外轮廓在既有建筑墙体外侧周围套建钢筋混凝土外筒；钢筋混凝土外筒重新设置基础，且与既有建筑重新构成钢筋混凝土筒中筒结构；新建钢筋混凝土外筒沉降，之后将既有建筑与新建钢筋混凝土外筒连接；在既有建筑与新建钢筋混凝土外筒之间的间隙中灌注高强无收缩灌浆料。本发明旧房改造再建施工中，梁柱等承重构件加固，以及改造后的建筑结构难以符合设计强度要求的问题。
