Abstract

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.

Description

technical field [0001] The invention relates to a connection device, in particular to a replaceable prestressed anchor bolt device, which can be used for prestressed anchor bolts on concrete foundations. Background technique [0002] In recent years, prestressed anchor bolt assemblies are mostly used in the foundation of wind power towers. Compared with the traditional embedded tower, the prestressed anchor bolt has better fatigue resistance, and the foundation concrete with uniform stress is always under pressure and has better durability. However, the defect of the existing prestressed anchor bolts is that once the anchor bolts are broken, they cannot be replaced, and the foundation concrete of the wind power tower needs to be knocked out to reinstall new anchor bolts. The project is large, long, costly, and troublesome to replace. Time-consuming and labor-intensive, it has become a bottleneck for the use of prestressed anchor bolts. [0003] The existing replaceable anc...
