Embodiment 1

[0039] This embodiment provides a composite connection node between a separate inner sleeve and a T-shaped piece connector, such as image 3 As shown, its components include the upper module unit square steel pipe column 7, the lower module unit square steel pipe column 1, the joint unit H-shaped steel beam 6, the independent inner sleeve 3, the upper T-shaped piece connector 8, and the lower T-shaped piece Connecting piece 9, high-strength bolt 5 and long through bolt 9.

[0040] Bolt holes are provided on the side wall of the independent inner sleeve 3, the upper end side wall of the square steel pipe column 1 of the lower module unit and the lower end side wall of the square steel pipe column 7 of the upper module unit are provided with bolts corresponding to the side wall of the independent inner sleeve 3 The high-strength bolt 5 connects the lower module unit square steel pipe column 1 and the independent inner sleeve 3 within the height range from the bottom of the indep...

Embodiment 2

[0050] This embodiment provides a composite connection node between an integral inner sleeve and a T-shaped connector. Limb unit H-shaped steel beam 6 , upper T-shaped piece connector 8 , lower T-shaped piece connected piece 4 , high-strength bolt 5 and long through-bolt 9 .

[0051] Bolt holes are provided on the side wall of the upper half of the welding inner sleeve 10, bolt holes corresponding to the side walls of the welding inner sleeve 10 are provided on the side wall of the lower end of the square steel pipe column 7 of the upper module unit, and the long through bolts 9 The tight vertical connection between the square steel pipe column 7 of the upper module unit and the square steel pipe column 1 of the lower module unit is realized through the corresponding bolt holes of the square steel pipe column 7 of the upper module unit and the welding inner sleeve 10 .

[0052] The web of the lower T-shaped connector 4 and the flange of the lower T-shaped connector 4 are provi...

Embodiment 3

[0061] This embodiment provides a composite connection node between a separate inner sleeve and a T-shaped connector. Its main structure is the same as that of Embodiment 1. In addition, it is also prefabricated by welding inwardly from the lower end of the square steel pipe column 7 of the upper module unit. The left angle steel connector 11, and then the left angle steel connector 11 is connected to the upper flange of the H-shaped steel structural beam 2 of the lower module unit through high-strength bolts 5, and the tight vertical connection between the square steel pipe column 7 of the upper module unit and the square steel pipe column 1 of the lower module unit is further strengthened. to the connection, such as Figure 7 shown.

Abstract

The invention relates to a composite connection node used for a coupled modularized assembling type steel structure. The node is of a node structure formed in a way that an upper / lower module unit ina coupled modularized assembling type building and an adjacent coupled unit are connected through an inner sleeve, a T-shaped element connecting element, high-strength bolts and long-penetration bolts. The inner sleeve is divided into a separation type inner sleeve and an integral type inner sleeve. Specifically, the composite connection node used for the coupled modularized assembling type steelstructure can be divided into two forms, including a separation type inner sleeve and T-shaped element connecting element composite connecting node (1) and an integral type inner sleeve and T-shapedelement connecting element composite connecting node (2). The node has the advantages of being reliable in connection, reasonable in stress, simple in construction and quick in disassembling and assembling.

Description

technical field [0001] The invention relates to a compound connection node for a modular assembly steel structure of joint limbs, in particular to a compound connection node of an inner sleeve and a T-shaped piece. Background technique [0002] Modular building refers to dividing the building into several space modules. All the structural framework, equipment, pipelines, decoration and fixed furniture in the modules have been completed, and the decoration of the exterior facade can also be completed. These modular components are transported to the construction site. Buildings that fit together like "building blocks". As a highly integrated prefabricated building, modular building is an advanced stage of construction industrialization development. It achieves high prefabrication rate and has technical advantages such as green environmental protection, efficient construction, and convenient disassembly. It is compatible with the standardized design and factoryization of prefab...
