Modularized steel frame structure and inter-module connecting device

Abstract

The invention relates to the technical field of building structures, in particular to a modularized steel frame structure and an inter-module connecting device. Most modular building structures in the prior art have the problems that under the transverse effect, modules slide relatively, and upper and lower module beams are difficult to bear force cooperatively. According to the technical scheme, the modularized steel frame structure comprises module units composed of module columns, ceiling beams and floor beams and connecting pieces used for connecting the module units; the floor beams and the ceiling beams are connected with two ends of the module columns to form frame structures; connecting plates and in-column sleeves are connected to form the connecting pieces; and the module columns of the module units are connected with the in-column sleeves of the connecting pieces in an inserted mode, and the beam ends of the floor beams and the ceiling beams are in natural lap joint with the connecting plates of the connecting pieces and are fixedly connected through connecting fasteners. The in-column sleeves and the module columns are combined for stress, the lateral stiffness of the structure is enhanced, relative slippage of the upper and lower module units is avoided, the floor beams and the ceiling beams of the upper and lower module units are cooperatively stressed through the connecting plates, and the beam end bearing capacity is effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a modular steel frame structure and a connecting device between modules. Background technique [0002] Modular steel structure buildings have the characteristics of light weight, high strength, fast construction speed, green energy saving, etc. Steel frame module units are the basic components of modular buildings, and the effective connection between units is an important prerequisite for ensuring the overall stability of the structure. In the prior art, the inter-module connection methods of modular steel structure buildings include the application of prestress in the column, the overall use of steel castings in the beam-column connection domain, special-structured inter-column connectors, column foot welding, and mortise and tenon connections. The construction is relatively complicated, the project cost is high, and on-site welding operations are required; and due ...
