Hollow anchor rod for anchor rod frame beam construction
The invention discloses a hollow anchor rod for anchor rod frame beam construction, and relates to the technical field of engineering support, the hollow anchor rod comprises an anchor head, a front rod body, a connector, a rear rod body and a stop-grouting plug, the front rod body is connected with the rear rod body through the connector, a base plate is welded on the rear rod body, the stop-grouting plug is sleeved in the rear rod body, and the front rod body is connected with the rear rod body through the connector. Centering devices are welded to the rear rod body at equal intervals and comprise bases, supports, semi-permeable membranes, annular grooves, double-layer frames and blocking air bags, the double-layer frames are fixed to the bases, the annular grooves are fixed to the bases through the supports and located between the double-layer frames, the blocking air bags are arranged in the annular grooves, and the semi-permeable membranes are arranged between the bases and the supports; a sleeve is arranged on the inner wall of the rear rod body, a communicating opening of the sleeve is formed in the base plate, and a ventilation pipeline is arranged in the sleeve and communicated with the blocking air bag. By arranging the centering device with the blocking air bag, segmented grouting of the long and thin anchoring hole is achieved, and insufficient grouting of the anchoring hole is avoided.
本发明公开了一种锚杆框架梁施工用中空锚杆，涉及工程支护技术领域，包括锚头、前部杆体、连接器、后部杆体和止浆塞，前部杆体与后部杆体通过连接器相连，后部杆体上焊接有垫板，止浆塞套装在后部杆体中，后部杆体上等间距焊接有居中器，居中器包括底座、支架、半透膜、环形槽、双层框架和封堵气囊，双层框架固定在底座上，环形槽通过支架固定在底座上，位于双层框架之间，封堵气囊设置在环形槽中，半透膜设置在底座与支架之间，后部杆体的内壁设置有套管，垫板上设置有套管的连通口，套管内设置有通气管路，通气管路与封堵气囊相连通。本发明通过设置带有封堵气囊的居中器，实现对于细长锚固孔的分段注浆，避免锚固孔注浆不充分。
