Embodiment 1

[0042] This embodiment provides a composite connection node of a separated inner sleeve angle steel 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 angle steel connector 8, the lower angle steel connector 4, High strength bolt 5 and long through bolt 9.

[0043] 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 and the long through bolt 9 pass through the lower module unit square steel pipe column 1, the upper module unit square steel pipe column 7 and the corresponding bolt holes of...

Embodiment 2

[0055] This embodiment provides a composite connection node between an integral inner sleeve and an angle steel connector, and its components include an upper modular unit square steel pipe column 7, a lower modular unit square steel pipe column 1 with a welded inner sleeve 10 on the top, and a joint unit H-shaped steel beam 6, upper angle steel connector 8, lower angle steel connector 4, high-strength bolt 5 and long through bolt 9.

[0056] 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 ...

Embodiment 3

[0068] This embodiment provides a composite connection node between a separate inner sleeve and an angle steel connector. Its main structure is the same as that in Embodiment 1. In addition, the left angle steel is prefabricated by welding the lower end of the square steel pipe column 7 of the upper module unit to the side. The connecting piece 11, and then the left angle steel connecting piece 11 and the upper flange of the H-shaped steel structural beam 2 of the lower module are connected through the high-strength bolt 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, Such as Figure 7 shown.

Abstract

The invention relates to a composite connecting node for a coupled modular assembled steel structure, and particularly relates to a composite connecting node of an inner sleeve and angle steel. The node is a node structure formed by connecting an upper module unit, a lower module unit and an adjacent coupled unit in a coupled modular assembled building with an inner sleeve, angle steel connectingpieces, high-strength bolts and long through bolts, and the components comprise an upper module unit square steel pipe column, a lower module unit square steel pipe column, a coupled unit H-shaped steel beam provided with a flush end plate, the inner sleeve, an upper angle steel connecting piece, a lower angle steel connecting piece, the high-strength bolts and the long through bolts. The node structure has the advantages of reliable connection, reasonable stress, simple structure and quick disassembly and assembly.

Description

technical field [0001] The invention relates to a composite connection node for a modular assembly steel structure of joint limbs, in particular to a composite connection node of an inner sleeve and an angle steel. 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...
