Outer frame for reinforcing and transforming precast slab brick-concrete structure and construction method of outer frame
The invention discloses an outer frame for reinforcing and transforming a precast slab brick-concrete structure and a construction method of the outer frame. The outer frame comprises a main body outer frame and an additional elevator frame. The main body outer frame is of a lightweight aggregate concrete structure and is formed by assembling external side columns, external middle columns, external corner columns and external ring beams. The external side columns, the external middle columns and the external corner columns are fixedly connected with existing constructional columns in the outer wall through expanded-base anchor bolts, and the external ring beams are vertically supported by the external side columns, the external middle columns and the external corner columns and are connected with the existing ring beams through chemical anchor bolts. And cast-in-place nodes are arranged at the intersections of the external ring beam, the external side columns, the external middle columns and the external corner columns, so that the external components are fixedly connected. The additional elevator frame is of a cast-in-place structure and is composed of a recycled concrete elevator shaft and a lightweight aggregate concrete gallery bridge. The system can be assembled and constructed, is good in integrity, can synchronously achieve the purposes of anti-seismic reinforcement of a prefabricated slab brick-concrete structure, additional elevator and wall external thermal insulation transformation, and is green, low-carbon, economical in manufacturing cost, safe and reliable.
本发明公开预制板砖混结构加固改造用外框架及其施工方法，外框架包括主体外框架和外加电梯框架。主体外框架采用轻骨料混凝土结构，由外加边柱、外加中柱、外加角柱与外加圈梁装配而成。外加边柱、外加中柱、外加角柱均与外墙内既有构造柱通过扩底锚栓固定连接，外加圈梁以外加边柱、外加中柱、外加角柱为竖向支撑并与既有圈梁通过化学锚栓进行连接。外加圈梁与外加边柱、外加中柱、外加角柱相交处设有现浇结点以实现外加构件间的固接。外加电梯框架采用现浇结构，由再生混凝土电梯井、轻骨料混凝土廊桥所组成。本发明可装配施工，整体性好，能够同步实现预制板砖混结构抗震加固、外加电梯及墙体外保温改造目标，绿色低碳，造价经济、安全可靠。
