Embodiment 1

[0030] Such as figure 1 and figure 2 The preparation method of a steel column base anchor bolt in place structure shown includes the following steps: (a) opening anchor bolt holes with the same arrangement and size on the two positioning templates, and adjusting the two positioning templates to be up and down (b) Insert the anchor bolts into the anchor bolt holes of the two positioning templates one by one, and pad the bottom surfaces of all the anchor bolts horizontally; (c) Adjust the two positioning templates to the level respectively; Then adjust the anchor bolts so that each anchor bolt is perpendicular to the positioning template; (d) connect the supporting steel bars between two adjacent anchor bolts, and the supporting steel bars are spot-welded with the anchor bolts; (e) Remove two positioning templates from above the anchor bolts, install leveling nuts on each bolt, and then reinstall a positioning template on each leveling nut; install and fix the positioning temp...

Abstract

The invention discloses a preparation method for a steel column base anchor bolt in-place structure. The preparation method comprises the steps that (a), same anchor bolt holes are formed in two positioning formworks, and the two positioning formworks are distributed up and down, directly face each other and are independently fixed; (b), anchor bolts are made to penetrate into the anchor bolt holes of the two positioning formworks one by one, and the bottom faces of all the anchor bolts are cushioned to be horizontal; (c) the two positioning formworks are adjusted to be horizontal, and then all the anchor bolts are adjusted to be perpendicular to the positioning formworks; (d) supporting steel strips are connected between every two adjacent anchor bolts; (e) the two positioning formworks are dismounted from the positions above the anchor bolts, then leveling nuts are mounted, and a positioning formwork is remounted; and (f) the remounted positioning formwork is adjusted to be horizontal through the leveling nuts, and fixing nuts are then mounted above the positioning formwork. The preparation method is used for solving the problems that in the prior art, steel column base positioning construction is low in speed and efficiency, and the purposes of simplifying site construction procedures during steel column base positioning and improving construction efficiency are achieved.

Description

technical field [0001] The invention relates to the field of steel structure building construction, in particular to a method for preparing a steel column foot anchor bolt in-situ structure. Background technique [0002] With the continuous promotion of steel structure buildings, the scale of various steel structure construction projects is increasing day by day, and projects such as steel structure industrial plants, steel structure residences, high-rise steel structures, and steel structure venues are increasing. In steel structure buildings, steel column feet generally adopt flat column feet connected by anchor bolts. The anchor bolt is a key part connecting the foundation and the superstructure, and is used to ensure the accurate positioning of the steel column. Therefore, the construction quality of the anchor bolt at the column foot directly affects the overall quality and safe use of the building structure. In the previous construction process, it was necessary to se...
