Abstract

The invention relates to an H-shaped steel beam bolt joint construction method. According to the H-shaped steel beam bolt joint construction method, in a steel structure deepening design stage, related simple measures are optimized into a design drawing, a processing factory conducts processing along with components, a connecting plate is fixed onto a steel beam by using a common bolt when the components leave the factory, part of mounting bolts are demounted during mounting on a site, the connecting plate is overturned, the steel beam is mounted, then high-strength bolt construction is conducted, mounting is quick, light and flexible, safety measures can be saved, and safety in the using process can be guaranteed; and by arranging temporary measures, on-site rapid positioning and mountingof full-bolt joints are guaranteed, meanwhile, the construction quality of the high-strength bolts is guaranteed, the construction cost is reduced while the working efficiency is improved, and the H-shaped steel beam bolt joint construction method is also suitable for construction of large steel beam web connecting plates.

Description

technical field

[0001] The invention relates to a full-bolt joint of an H-shaped steel beam in the construction industry, in particular to a construction method for a bolted joint of an H-shaped steel beam. Background technique

[0002] At present, the H-shaped steel girder rigid joints of steel structures mainly include bolted joints, fully welded joints, and full bolted joints. During the construction of common full bolted joints or steel beam connecting plates of bolted welded joints, temporary steel beams are firstly constructed. After installation, it is necessary to use a hanging cage or an operating platform to loosen the connecting plates. After installation, replace the high-strength bolts, and then carry out the initial and final screwing construction of the high-strength bolts. The construction process is cumbersome, especially for the web connecting plates and connecting plates. The weight is heavy, the installation is difficult, the installation efficiency is lo...
