Anchor rod anti-pulling test structure after anchor sealing based on clamping and fixing
The invention relates to the technical field of anchor rod anti-pulling structures, and discloses an anchor rod anti-pulling test structure after anchor sealing based on clamping and fixing. The anchor rod anti-pulling test structure comprises an anchorage device arranged on the outer surface of a building and a jack abutting against the building, the lower portion of the jack is internally provided with a sleeve cavity with a downward opening, and the anchorage device is arranged in the sleeve cavity. An annular gap is formed between the inner side wall of the sleeve cavity and the anchorage device; a plurality of clamping structures arranged in a surrounding mode in the circumferential direction of the annular gap are arranged in the sleeve cavity, the clamping structures are provided with telescopic heads, the telescopic heads are inserted into the annular gap, and the jack and the anchorage device are relatively fixed. According to the anchor rod anti-pulling test structure after anchor sealing based on clamping and fixing, in this way, the anchorage device is clamped and fixed through the telescopic heads on the multiple clamping structures, connection between the jack and the anchorage device is achieved, when the jack exerts downward pressure on the outer surface of the building, the jack generates reverse tensioning force on the clamping structures, and the reverse tensioning force is indirectly exerted on the anchorage device; therefore, the holding load of the anchor rod can be measured, and the anchor rod anti-pulling test after anchor sealing can be smoothly carried out.
本发明涉及锚杆抗拔结构的技术领域，公开了基于夹持固定的封锚后的锚杆抗拔试验结构，包括设置在构建物的外表面上的锚具以及抵压在构建物上的千斤顶，千斤顶的下部中设有开口朝下的套腔，锚具置于套腔内，套腔的内侧壁与锚具之间形成有环形间隔；套腔内设有多个沿着环形间隔的周向环绕布置的夹持结构，夹持结构具有伸缩头，伸缩头插入在环形间隔中，将千斤顶与锚具之间相对固定；这样通过多个夹持结构上的伸缩头将锚具夹持固定，实现了千斤顶与锚具之间的连接，当千斤顶对构建物的外表面施加朝下压力时，千斤顶对夹持结构产生反向的张拉力，也就间接地对锚具施加反向的张拉力，从而可以测定锚杆的持有荷载，顺利进行封锚后的锚杆抗拔试验。
