Anti-floating anchor cable for building
The invention relates to the technical field of building construction, and discloses an anti-floating anchor cable for a building. The anti-floating anchor cable for the building comprises a pluralityof unbonded steel strands, a plurality of sections of bearing body assemblies are sequentially arranged, and each section of bearing body assembly comprises a bearing plate and a guide support, and the front end of each unbonded steel strand is fixedly connected to each section of bearing plate through the extrusion of an extrusion sleeve/spring. According to the anti-floating anchor cable for the building, the multiple sections of bearing plates and the supports are connected and arranged at the front ends of the unbonded steel strands to form a pressure type anti-floating anchor rod, and itcan be guaranteed that concrete on the tensile edge of a component does not generate tensile stress; the problem of incomplete sediment treatment during drilling is solved through the guide supports,and the phenomenon that a bottom plate and a column beam crack due to the action shear force formed by floating of underground water and the gravity of the building is avoided by adopting the structural mode of the unbonded steel strands and the multiple sections of bearing bodies, and the problem that the design service life of the building cannot be met due to failure of anchoring pulling resistance caused by corrosion of an anti-floating anchor rod metal surface body in an underground environment all the year round is solved.
本发明涉及建筑施工技术领域，公开了一种建筑用抗浮型锚索，包括若干根无粘结钢绞线，依次设置多段承载体组件，承载体组件包括承载板和导向支架，无粘结钢绞线的前端通过挤压套/簧的挤压分别固定连接于各段承载板。本发明提供的一种建筑用抗浮型锚索，在无粘结钢绞线的前端连接设置多段承载板和支架形成压力型抗浮锚杆，可保证构件受拉边缘混凝土不产生拉应力。通过导向支架解决了钻孔时沉渣处理不净的问题，通过采用无粘结钢绞线和多段锚固承载体结构方式，解决了地下水上浮与建筑物重力形成的作用剪切力造成底板、柱梁开裂现象；解决了抗浮锚杆金属表体常年在地下环境中的产生锈蚀所导致的锚固抗拔力失效而无法满足建筑物的设计使用年限。
