Embodiment 1
[0051] Such as Figure 1 to Figure 7 , Figure 9 to Figure 10 As shown, a positioning bracket for pre-embedded steel column anchor bolts provided in this embodiment includes an external bracket 1, a positioning steel plate 2, and a positioning support frame 3. The external bracket 1 includes a left half bracket 11 and a right half bracket set separately. The bracket 12, the left half bracket 11 and the right half bracket 12 can be detachably arranged on the foundation cushion 4 and are located on both sides of the outer sides of the platform reinforcement 5, and the platform reinforcement 5 is the steel column foundation for fixing the steel column. For the cap steel bars before pouring, the cap cap steel bars 5 are arranged on the foundation cushion 4, the positioning steel plate 2 is located above the cap cap steel bars 5 and erected between the left half bracket 11 and the right half bracket 12, and the left half bracket 11 and the right half bracket The right half bracket...
Embodiment 2
[0058] Such as Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the cross bar 32 at the position corresponding to the positioning hole 20 is surrounded by a side bar 34 to form a fixed through hole 35 matching with the anchor bolt 6, and the side bar 34 Comprising a long cross bar 341 welded on one side of a cross bar 32, a short longitudinal bar 342 welded between the cross bar 32 and the long cross bar 341, the short longitudinal bar forms a strip between the cross bar 32 and the long cross bar The shape space is divided into a plurality of fixed through holes 35, the cross bar 32 and the long cross bar 341 are parallel to each other, and the bottom of the anchor bolt 6 runs through the fixed through hole 35, so that the fast limit and fixation of the bottom of the anchor bolt 6 can be realized, and it is more convenient. It is stable and effectively prevents the anchor bolts 6 from shifting due to concrete impact and vibration. The two en...
