Background

The modular assembly type building is a building which is constructed by transporting the modular units manufactured in a factory to a construction site through a transport vehicle, hoisting the modular units in place by using a hoisting device, connecting key structure nodes and pipelines among modules, and finishing seam treatment. The modular unit refers to a single room or a three-dimensional building space unit with certain building functions, which is manufactured in advance by a factory. The steel structure has the characteristics of light dead weight and easy assembly, and becomes a preferred structural system of the modular building. The basic module unit steel skeleton can adopt the forms of a frame module, a frame support module and the like, and when the number of layers of modular buildings is large, a local steel plate shear wall can be arranged in the basic module unit to form a frame-shear wall module unit. The connection between the building module units is the key part of the steel structure module building, the node connection of the steel structure module building module columns at home and abroad at present has the structural forms of bolt (rivet) connection, connecting piece splicing connection, prestressed tendon connection, hybrid connection and the like, but the module columns of the connection forms can not bear tensile force or can not bear larger tensile force, and are not in line with the relevant requirements of the building earthquake-resistant design specification (GB 50011) in China, and are only suitable for the steel structure module building with less layers (1-3 layers).

Because the height of the house of the multi-storey or medium-rise modular building is larger, the requirements on the bearing capacity and the lateral stiffness of the modular building are higher, and higher requirements are provided for the modular unit and the modular column joint connection structure of the modular unit. The above-mentioned connection structure of each module column node is not suitable for the multi-storey and middle-high-rise steel structure module building with a large number of layers. Chinese patent 201320343028.6 discloses a connection node structure of main module unit frame columns adjacent to each other up and down in a modular building, chinese patent 201510357426.7 discloses an assembly structure for applying prestress to the center of the section of a steel structure module frame column, and chinese patent 201510358851.8 discloses an assembly structure for applying prestress to the periphery of the section of a steel structure module frame column. Although the module column connection node structures disclosed in these patents can be applied to multi-storey steel structure module buildings and have strong earthquake resistance and wind load resistance, the process is complex, and the structure cannot be applied to modular buildings with more storeys, and still has certain limitations.
