[0001] The utility model relates to the field of anchor bolts, in particular to a positioning device for fixing steel structure anchors. Background Art

[0002] As people's living standards continue to improve, so too do the demands placed on buildings. Steel columns directly connected to concrete floors via anchor bolts are becoming increasingly common, and designers are demanding higher and higher accuracy in their positioning. To ensure precise positioning of steel columns, the placement and positioning of anchor bolts before concrete pouring is crucial.

[0003] Since the embedding accuracy of anchor bolts directly affects the installation accuracy of steel columns and the installation accuracy of the entire steel structure project in the later stage, any slight error or shaking in the positioning of anchor bolts during the embedding process will have serious consequences. Traditional anchor bolts are generally placed directly on the steel bars of the concrete floor. This placement method cannot firmly fix the anchor bolts. During the concrete pouring process, the anchor bolts are easily displaced, which in turn affects the installation and fixation of steel columns in the later stage.

[0004] To this end, the utility model proposes a positioning device for fixing steel structure foundation to solve the above-mentioned technical problems. Utility Model Content

Thus, the position between the anchor bolts 2 can be fixed through the settings of the support plate 1 and the fixing plate 5, avoiding the problem of the anchor bolt 2 shifting during concrete pouring. After the bottom of the anchor bolt 2 is poured, then turn out the limit nut 3 and remove the support plate 1 and the fixing plate 5, which is more convenient.

[0025] Embodiment 2: On the basis of Embodiment 1, in order to facilitate the positioning of the anchor bolt 2, a support plate 1 and a fixing plate 5 are provided.
