Prefabricated fabricated modular frame joint and fabricating method thereof

Abstract

The invention provides a prefabricated fabricated modular frame joint and a fabricating method thereof. Prefabricated H-shaped steel concrete columns are connected to the tops and / or the bottoms of joint modules through bolts to achieve connecting of vertical columns, and H-shaped steel beams are connected to the side edges in the horizontal direction of the joint modules through bolts in a weldedmode to achieve connecting of horizontal beams and columns; during construction on-site fabricating, the prefabricated and processed joint modules are directly hoisted to the tops of the prefabricated columns to be mounted, then are reliably connected with the steel beam-upper prefabricated columns through the high-strength bolts in a welded mode, and operation is easy and convenient; and throughthe steel structure splicing technology, the construction period can be shortened greatly, the fabricating efficiency is improved, connecting is conducted at a joint core area through the bolts in the welded mode, connection without reinforcing bars is achieved, the problems of complex cross construction, difficulty reinforcement binding and post pouring concrete and formwork supporting of the joint core area can be effectively avoided, and the design goal of being safe, reliable, efficient, fast, controllable in cost and environmentally friendly of a prefabricated fabricated-type structure is achieved.

Description

technical field [0001] The invention relates to the field of construction, in particular to a prefabricated modular frame node and an assembly method thereof. Background technique [0002] Since the 21st century, people have put forward new requirements for building energy conservation and building environmental protection. The development of building industrialization is one of the current trends in the development of building technology in the world. Compared with traditional cast-in-place methods, the use of prefabricated buildings has many advantages, such as short construction period, energy saving, environmental protection, and the ability to ensure construction quality and speed up urbanization. The biggest difference between prefabricated prefabricated concrete structures and cast-in-place concrete structures In the process of factory prefabrication and on-site splicing, the connection method and the method of connecting nodes have become the focus of research on pre...

AI Technical Summary

Problems solved by technology

[0009] Research on the joint connection method of stiffened concrete beams and columns is also limited to the bolt-welded connection at the edge of the column or the reinforced ring connection. Not only is the construction complicated, but the joint size is often limited by the building's use function
