Abstract

The invention discloses a raft foundation bolt embedded structure and method. The method comprises the following steps that preparation is carried out, specifically, construction preparation is carried out according to construction drawings; concrete cushion pouring is carried out, specifically, cushion pouring is carried out after a bolt bracket fixing iron piece is arranged; a bolt bracket is installed, the bolt bracket is fixed to the fixing iron piece, and the fixing iron piece is used as a supporting point of the bolt bracket; drilling is carried out, specifically, firstly the installation position of a bolt is determined, and drilling is carried out at the installation position of the bolt; and the bolt is installed, specifically, the bolt is installed at the installation position ofthe bolt, a nut is put on, and the nut is spot welded to a box iron fixed frame after the position of the center line of the bolt is adjusted. According to the raft foundation bolt embedded structureand method, according to the foundation size and construction progress, integral planning design of the bracket is carried out in advance, modular construction is carried out, and the construction efficiency is improved. A fixed system is convenient and firm to build, welding is required most and special technologies are not required, and the construction difficulty is reduced. Positioning of theposition of the bolt is simple and accurate, and control of the scale height of the bolt is light and flexible.

Description

technical field [0001] The invention relates to a pre-embedded structure and method for pre-embedding a channel steel bracket on site to fix the bolts to control the pre-embedded precision of the bolts when the raft-shaped foundation bolts of the plant equipment are pre-embedded. Background technique [0002] The number of pre-embedded bolts in the equipment foundation is large, the model specifications are complex and changeable, the geometric shape of the bolt distribution changes greatly, and there are many bolts on the side; the variation of the bolt elevation is complicated, which adds great difficulty to the bolt embedding. Ensuring the embedding accuracy of bolts is a difficult point in the project, which directly determines the quality of the project. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a raft foundation bolt pre-embedded structure and installation method. [0004] Th...
