A high-precision embedding method for large-size pre-embedded slabs

Abstract

The invention provides a high-precision burying method for a large-size pre-buried board. According to the construction sequence, the high-precision burying method comprises the following steps that distribution of foundation bar-mat reinforcement on a bottom layer is inspected on site, long reinforcement heads are welded to the corresponding positions of the bottom of the pre-buried board, and then a rail, a rail beam and an equipment bottom plate are assembled according to the design requirement; it is required that the pre-buried board and the equipment bottom plate are in close contact without clearances and are subjected to firm spot welding, equipment is wholly hoisted to the mounting position through a crane, and leveling, aligning and elevation locating are carried out according to standard requirements; the equipment is fixed through auxiliary components, the long reinforcement heads at the bottom of the pre-buried board and the foundation bar-mat reinforcement are welded, and finally pouring is carried out through high-strength non-shrinkage grouting materials. The high-precision burying method is easy to operate and high in practicality, alignment work efficiency can be greatly improved, mounting precision can be practically guaranteed, cost can be effectively reduced, and the problems that in the conventional construction process pouring process, reinforcement is prone to deform due to large loads, and the board burying precision is influenced by connecting machine vibrating and foundation hot expansion and cold shrinkage are solved.

Description

technical field [0001] The invention relates to the technical field of large-scale equipment installation and construction, in particular to a high-precision embedding method for large-size pre-embedded slabs. Background technique [0002] The walking beam walking support system of pickling leveling line includes track, track beam and equipment floor. During the installation process, adjusting pads are not allowed between the track and the track beam, the track beam and the equipment floor, the equipment floor and the embedded slab, and are directly installed in place at one time, which requires high embedding accuracy for the embedded slab. The traditional method first sets the embedded slab according to the design elevation and center, welds and fixes the anchors and the foundation steel bars, and then pours them all at once. In this method, the steel bars bear a large load and are easy to deform. During the pouring process, the concrete is mechanically vibrated and easy t...
