Prestressed anchor rod anti-floating structure and construction method thereof
The invention discloses a prestressed anchor rod anti-floating structure. The prestressed anchor rod anti-floating structure comprises a prestressed anchor rod and a basement bottom plate, the prestressed anchor rod comprises an anchor rod body and a rib body located in the center of the anchor rod body, and a tensioning structure is arranged at the top end of the anchor rod body; the lower end ofthe rib body is fixed to the lower part of the anchor rod body, and a hollow cavity extending along the axis of the anchor rod body is arranged on the upper part of the anchor rod body; the upper part of the rib body penetrates out of the hollow cavity and is fixedly connected with the tensioning structure, and a gap is formed between the hollow cavity and the rib body; and an anchoring structureis further arranged above the tensioning structure, the anchoring structure is located in the basement bottom plate, and the top of the rib body is fixedly connected with the anchoring structure. Theinvention further relates to a construction method of the prestressed anchor rod anti-floating structure. The prestressed anchor rod anti-floating structure has the advantages of being simple and convenient to construct and good in economical efficiency, tensioning holes do not need to be formed in the basement bottom plate, the construction progress can be improved, and basement bottom plate leakage is prevented.
本发明公开了一种预应力锚杆抗浮结构，其包括预应力锚杆和地下室底板，所述预应力锚杆包括锚杆体和位于所述锚杆体中心的筋体，锚杆体的顶端设置有张拉结构；所述筋体的下端固定于所述锚杆体下部，所述锚杆体的上部具有沿着所述锚杆体轴线延伸的中空腔体；所述筋体的上部从所述中空腔体穿出，并与张拉结构固定连接，所述中空腔体和所述筋体之间具有间隙；所述张拉结构的上方还具有锚固结构，所述锚固结构位于所述地下室底板内，所述筋体的顶部与所述锚固结构固定连接。本发明还涉及上述预应力锚杆抗浮结构的施工方法。本发明具有施工简便、经济性好的特点，不需要在地下室底板上开设张拉孔洞，有利于提高施工进度，防止地下室底板渗漏的发生。
