Replaceable prestressed anchor bolt device and mounting and replacement construction method thereof
The invention discloses a replaceable prestressed anchor bolt device. The replaceable prestressed anchor bolt device comprises an upper anchor plate (1), a lower anchor plate (2), anchor bolts (3) connected with the upper anchor plate (1) and the lower anchor plate (2) and plastic casing pipes (7) arranged on the peripheries of the anchor bolts (3) in a sleeving manner. The upper ends and the lower ends of the plastic casing pipes (7) are shrunk and sealed by thermal shrinkable sleeves (8). Nonmetal leveling nuts (6) are arranged on the thermal shrinkable sleeves (8) at the upper ends of the plastic casing pipes (7), and upper nuts (9) are arranged at the tops of the anchor bolts (3). The bottoms of the anchor bolts (3) and bottom sealing assemblies (4) are fixed. The replaceable prestressed anchor bolt device is reasonable in structural design, each anchor bolt can be freely replaced after a concrete foundation is completed or a fan runs, and a large amount of manpower and a large number of material resources can be saved; replacement cost is low, and efficiency is high; and many defects in the prior art can be overcome.
