A high-precision installation method of a bull's-eye substrate and a sealing cylinder base

Abstract

The invention, which belongs to the building field, particularly relates to a high-precision mounting method of a target center substrate and a sealing cylinder pedestal. The mounting method comprises the following steps: a, manufacturing a substrate positioning sleeve rack; b, manufacturing a pedestal positioning sleeve rack; c, carrying out measurement and setting out; d, carrying out pre burying of substrate positioning sleeve rack steel bar inclined support units and ground foot bolt angle irons; e, carrying out pre burying of pedestal positioning sleeve rack steel bar inclined support units and anchor rod angle irons; f, carrying out bottom concrete pouring; g, installing a substrate positioning sleeve rack and ground foot bolts; h, installing the pedestal positioning sleeve rack and anchor rods; if, carrying out concrete pouring under the substrate and the pedestal; j, installing the substrate and carrying out secondary grouting; and k, installing the pedestal and carrying out secondary grouting. Therefore, the mounting precision and strength can be guaranteed.

Description

technical field [0001] The invention belongs to the field of construction, and more specifically relates to a high-precision installation method for a bull's-eye substrate and a sealing cylinder base. Background technique [0002] as attached figure 1 and figure 2 As shown, the bullseye is composed of the base plate 1 and the sealing cylinder base 2, the base plate and the sealing cylinder base are arranged concentrically, and the sealing cylinder 0 is located on the sealing cylinder base 2. At present, the installation of the base plate and the base generally adopts the following methods: 1. The anchor rod and the steel plate are welded as a whole and then pre-embedded into the concrete structure, that is, the anchor rod is first welded to the steel plate, and then the whole is welded to the structural steel bar for fixing; 2. The anchor bolts are pre-embedded first, and then the steel plates or equipment are installed, that is, after the reinforcement of the reinforced ...

AI Technical Summary

Problems solved by technology

[0003] In the above 1, since the anchor rod is welded on the structural steel bar, it will be displaced due to steel bar displacement, bending, etc. during the concrete pouring process, which will affect the positioning accuracy; for the steel plate with a large area, the concrete cannot be vibrated, or the vibrated During the process, there will be defects such as honeycomb and non-compactness, which will reduce its bearing capacity

In the above 2, due to the large number of anchor bolts and large-scale pre-buried, when welding on the steel bars, the relative position and elevation of the anchor bolts are often affected by the displacement of the steel bars, and it is difficult to ensure the relative position and elevation of the anchor bolts. Accuracy of elevation
