Modular steel structure connecting joint adopting grouting technology and construction method thereof

Abstract

The invention provides a modular steel structure connecting joint adopting a grouting technology and a construction method thereof. A plurality of through holes for allowing cross-shaped inserting pieces to penetrate through are formed in a positioning ring; an upper steel pipe module column and a lower steel pipe module column are arranged on the parts, located above and below the positioning ring, of the cross-shaped inserting pieces in a sleeving mode correspondingly; the lower end of the upper steel pipe module column and the upper end of the lower steel pipe module column are sealed with the positioning ring; a sealing bottom plate is arranged at the position, below the cross-shaped inserting pieces, in the lower steel pipe module column; the lower steel pipe module column and the upper steel pipe module column are filled with grouting materials; a grouting hole is formed in the lower steel pipe module column; the grouting hole is formed above the sealing bottom plate; a slurry outlet hole is formed in the upper steel pipe module column; the slurry outlet hole is located above the upper ends of the cross-shaped inserting pieces; and the lower steel pipe module column and the upper steel pipe module column are connected with H-shaped steel module beams. According to the modular steel structure connecting joint adopting the grouting technology and the construction method thereof, the mechanical property is good, the structure is simple, the construction is convenient, the prefabrication rate is high, and reliable connection between steel structure modules can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction engineering, and relates to a modular steel structure prefabricated cabin and a connection node structure between box-type steel structure modules, in particular to a modular steel structure connection node using grouting technology and a construction method thereof. Background technique [0002] The new steel structure building has the advantages of high rigidity, light weight, short construction period, energy saving and environmental protection. The node is the core of the steel structure modular building design, and the reliability of the node directly affects the safety of the module as a whole. Although scholars at home and abroad have proposed joints for steel structure box buildings or container buildings, the existing joint forms require large operating space and long connection time, and the operating space for multi-box combined joints is limited. Therefore, adopting a connection ...
