Problems solved by technology

[0004] The purpose of the present invention is to make up for the defects of the prior art, and provide a structure and method for pre-embedded offset treatment of anchor bolts, which solves the problem of the large-diameter (diameter greater than 36mm) anchor bolt pre-embedded offset size in the prior art is large ( If the deviation size is greater than 1.5 times the bolt diameter) and cannot be solved by adjusting the positioning of the anchor bolt itself, the invention can quickly solve the problem of pre-embedded deviation of the anchor bolt, with low cost and fast speed

Embodiment Construction

[0023]Such asfigure 1 ,2As shown, an anchor bolt pre-embedded offset treatment structure includes a plurality of offset anchor bolts 2, a transition steel plate 4, a plurality of correctly positioned anchor bolts 3, and a steel column base plate 6; The offset anchor bolts 2 are pre-embedded in-situ anchor bolts, anchored in the concrete short column or concrete beam 1, and the other end is exposed. After the axis is retested, the original anchor bolts are offset, which cannot meet Steel column installation requirements; the transition steel plate 4 is welded on the top of the plurality of offset anchor bolts 2, and the transition steel plate 4 is provided with a plurality of through holes for the anchor bolts 3 to pass through. One correctly positioned anchor bolt 3 corresponds to a plurality of offset anchor bolts 2, and the lower ends of the plurality of correctly positioned anchor bolts 3 respectively pass through a plurality of through holes on the transition steel plate 4 and s...

Abstract

The invention discloses a foundation bolt pre-embedded deviation treatment structure and method, and relates to the field of steel structure engineering construction. The foundation bolt pre-embeddeddeviation treatment structure comprises a deviated foundation bolt, a transition steel plate is arranged on the upper portion of the deviated foundation bolt, the transition steel plate is connected with the deviated foundation bolt through plug welding, a correctly-positioned foundation bolt is arranged on the upper portion of the transition steel plate, the correctly-positioned foundation bolt is connected with the transition steel plate through welding, and a steel column is connected with the correctly-positioned foundation bolt. According to the foundation bolt pre-embedded deviation treatment structure and method, the correctly-positioned foundation bolt is reinstalled on the deviated foundation bolt through the transition steel plate, and a steel column foot bottom plate is directlyconnected with the correctly-positioned foundation bolt, so that the pre-embedded deviation problem of the large-diameter foundation bolt is solved; and meanwhile, the construction is convenient, theaccuracy is high, the cost is low, and the problem of deviation of the pre-embedded foundation bolt can be well solved.

Description

Technical field[0001]The invention relates to the technical field of steel structure engineering construction, in particular to a structure and method for pre-embedded and offset treatment of foundation bolts.Background technique[0002]With the beginning of a new round of infrastructure construction, more and more industrial plants are under construction. Most of the industrial plant structures are light-steel portal steel frames, which have large spans, long lengths, easy installation and fast construction. Etc. Lightweight steel portal steel frame usually adopts embedded anchor bolts for positioning and installation of steel columns.[0003]The anchor bolt pre-embedding is the first step in the construction of the portal steel frame. The accuracy of the pre-embedding directly affects the installation and use of the portal steel frame; in the actual construction process of the anchor bolt pre-embedded, due to the site segmentation and conditions A series of reasons such as restriction...
