Mounting method of beam-column connecting joints of prefabricated house steel structure

Abstract

The invention relates to steel structure beam-column connection, and particularly relates to a mounting method of beam-column connecting joints of a prefabricated house steel structure. The mounting method comprises the steps that welding seams are calculated, and blanking is conducted in a manufacturing factory for standby application according to the specification and the plate thickness of selected clamping head plates; one end of each selected clamping head plate is welded to the end of a steel beam; after the steel beam welded with the clamping head plates is hoisted to the mounting position, the other ends of the clamping head plates are erected on a bracket of a steel column, and then a hoisting tool is removed; the joints of the beam column are connected by mounting workers through bolts; and the connecting joints are welded finally according to the drawing requirements, and mounting of the whole beam column is completed. According to the mounting method of the beam-column connecting joints of the prefabricated house steel structure, hoisting tools are not needed for whole-process cooperation, the mounting workers can conduct grouping operation, and the mounting efficiency is high.

Description

technical field [0001] The invention relates to beam-column connections of steel structures, in particular to an installation method for beam-column connection nodes of assembled residential steel structures. Background technique [0002] Prefabricated structural buildings are in line with the development of the industry. With the adjustment of the national industrial structure and the advocacy of the construction industry for the concept of green and energy-saving buildings, prefabricated buildings have received more and more attention. As a typical representative of green buildings, steel structures greatly reduce the amount of sand, stone, ash, etc. When buildings are demolished, most of the materials can be recycled or degraded, which can effectively reduce construction waste. [0003] The steel skeleton of the prefabricated house is mostly connected by beam-column bolts. The traditional installation of steel beams is to use tower cranes or other hoisting tools. The con...
