在防水构筑物工程中,自制止水螺栓直接预埋在池壁混凝土内部,待模板拆除后,剔凿止水螺栓两端混凝土、切割螺栓端头并抹防水砂浆,经过长期浸泡后,抹防水砂浆易脱落,从而造成螺栓锈蚀,严重影响构筑物的使用功能和结构寿命。而工具式止水螺栓就可以完全克服这一缺点,其不仅防水效果好,而且安拆方便,周转利用率高,成本低。一、工具式止水螺栓的构成工具式止水螺栓为普通碳钢
In the waterproofing project, the self-made stop bolt is directly embedded in the concrete inside the concrete wall. After the template is dismantled, pick concrete at both ends of the stop bolt, cut the end of the bolt and apply waterproof mortar. After long-term soaking, Easy to fall off, resulting in corrosion of bolts, seriously affecting the use of structures and structural life. The tool-type water stop bolt can completely overcome this shortcoming, which not only waterproof effect, but also easy to install, turnover utilization, low cost. First, the composition of the tool-type seal bolt Tool-type seal bolt for ordinary carbon steel
