Precise positioning frame for large steel columns and equipment foundation fixing bolts and construction method of precise positioning frame

Abstract

The invention discloses a precise positioning frame for large steel columns and equipment foundation fixing bolts and a construction method of the precise positioning frame. The precise positioning frame comprises a supporting frame for placing the fixing bolts; a profile steel bracket is surrounded at the outer side of the supporting frame; the profile steel bracket comprises vertical rods, connecting rods, a profile steel bracket top frame and a positioning sleeve frame placing platform, wherein the vertical rods are distributed at intervals, each connecting rod is connected between every two adjacent vertical rods, the profile steel bracket top frame is detachably connected between upper end parts of the vertical rods through a connecting bolt, and the positioning sleeve frame placing platform is connected on the profile steel bracket top frame; the fixing bolt positioning sleeve frame is laid on the positioning sleeve frame placing platform; and a positioning hole is arranged on the fixing bolt positioning sleeve frame. The positioning frame ensures that large steel structure column bolts or large equipment foundation fixing bolts are more precise to install, the defect that bolts can be adjusted and fixed only before concrete is cast and cannot be precisely adjusted during the casting of concrete in the traditional process is avoided, moreover, the positioning frame can be partly turned over to be operated, so that the construction cost is saved, and the construction progress is accelerated.

Description

technical field [0001] The invention relates to a positioning frame capable of adjusting the installation accuracy of large-scale steel structure column foot bolts or large-scale equipment foundation positioning bolts, and a construction method for installing large-scale steel columns and equipment foundation fixing bolts using the positioning frame. Background technique [0002] In many industrial and civil buildings, there are more and more large-scale steel columns and equipment foundations, and the requirements for installation accuracy are getting higher and higher. The installation accuracy requirements are also greatly improved. Taking the installation of column bolts in a certain project as an example, each column foot has 20 column foot bolts. Each column foot bolt has a diameter of φ80mm, a length of 3450mm, and a weight of 136Kg. The total weight of the foot bolts is 2.7 tons. The installation accuracy of each group of foot bolts is allowed to deviate from ±2mm, a...
