外墙止水钢板与框架柱节点加固优化方案

Reinforcement Optimization Scheme of Outer Wall Steel Strip and Frame Column Node

根据熔制基础工程设计情况,外墙施工缝通过设置止水钢板进行防水,止水钢板起到了切断水渗透路径的作用。但止水钢板与框架柱交叉处,部分钢筋特别是起横向约束的核心水平箍筋被打断,存在安全隐患。为有效减少核心箍筋被打断且完好修复,同时保证止水钢板的防水效果,该文结合以往项目的现场经验,提出止水钢板与框架柱节点的加固处理措施。

According to the design of melting foundation engineering,steel strip shall be set for waterproof of construction joints of outer wall to cut off the water penetration path.However,at the intersection of steel strip and frame column,a portion of steel bar,especially the core horizontal stirrup which plays the role of transverse restraint,is interrupted,which will cause potential safety hazards.In order to effectively reduce the impact of core stirrups being broken and repaired in good condition,and at the same time to ensure the waterproof effect of steel strip,this paper proposed the reinforcement treatment measures of steel strip and frame column joints based on the field experience of previous projects.
