Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1 to 7 As shown, this utility model embodiment provides a high-precision anchor bolt device for prefabricated pre-reserved openings. At least one pre-reserved reinforcing bar 2 is provided horizontally within the prefabricated pre-reserved opening 1, which is located within precast concrete 10. The high-precision anchor bolt device includes: at least one connecting screw 42 vertically connected to at least one pre-reserved reinforcing bar 2; a first adjustment mechanism including an adjustment plate 41 movably disposed on at least one connecting bolt 3 along the length of two connecting bolts 3; and a second adjustment mechanism including at least one adjusting sleeve 51 movably disposed on the adjustment plate 41 along the depth of the prefabricated pre-reserved opening 1 and used for inserting and connecting the anchor bolt 7. Preferably, a binding connector 8 is provided at the connection point between the at least one pre-reserved reinforcing bar 2 and the at least one connecting bolt 3. In this embodiment, the binding connector 8 is a steel wire rope.
