Mounting process of steel structure pre-buried bolt

Abstract

The invention discloses a mounting process of steel structure pre-buried bolts. The mounting process comprises the following steps: determining the pre-buried positions of the pre-buried bolts and ejecting out the positioning axes of the pre-buried bolts, and binding reinforcements into a reinforcement cage according to the requirement; checking the skeleton sizes of the pre-buried bolts, placing the pre-buried bolts in the reinforcement cage, sleeving the pre-buried bolts by a positioning steel formwork, adjusting the positioning axis of the positioning steel formwork, and welding the pre-buried bolts with the main reinforcements of the reinforcement cage; after the mounting and fixing of the pre-buried bolts are completed, detaching the positioning steel formwork, and checking the plane positions and the elevations of the pre-buried bolts; conducting pouring of foundation concrete; and after final setting of the foundation concrete, cleaning all the pre-buried bolts thoroughly, smearing with solid grease, and tightly packing with an adhesive tape. The mounting process has the advantages that the mounting process is simple, the pre-burying precision is high, the pre-buried bolts do not shift and sink, concrete is uniform in strength, the integrality is high, the anti-drawing strength and the shearing strength are high, and the construction is convenient, not only is the axes displacement of the pre-buried bolts ensured, but also the mounting speed of the pre-buried bolts can be increased, and labor and time are saved.

Description

technical field [0001] The invention belongs to the field of pre-embedded bolt installation, in particular to a steel structure pre-embedded bolt installation process. Background technique [0002] Due to the advantages of high strength, light weight, good seismic performance, fast construction speed and high degree of industrialization, the steel structure has been developed rapidly. The installation accuracy of steel support columns and embedded bolts of steel structure buildings has gradually become a key process of construction, otherwise there will be deviations exceeding the allowable deviation of the specifications and even lead to serious defects that the bolts cannot enter the holes. The pre-embedded bolt installation process in the prior art determines the appropriate installation method according to the different space dimensions and construction requirements of the steel structure. The pre-embedded bolt is the basis for the installation of the upper steel structu...

Problems solved by technology

The pre-embedded bolt installation process in the prior art determines the appropriate installation method according to the different space dimensions and construction requirements of the steel structure. The pre-embedded bolt is the basis for the installation of the upper steel structure project, which directly affects the verticality, Squareness and column-beam connection accuracy will affect the installation quality of the steel structure. The accuracy of pre-embedding is very high. For the occasions with large construction area and dense installation of pre-embedded parts, it is difficult to locate and fix the bolts.
