Problems solved by technology

Due to the particularity of modular buildings, when assembling, it is necessary to realize the connection of two frame columns and four frame beams at the node, or the connection of four frame columns and eight frame beams at the node, or even the connection of eight frame columns and ten frame beams at the node. The connection of six frame beams is more complicated than the traditional steel structure node structure

Embodiment 1

[0033] A modular steel structure node is formed at the splicing place between modular units; the modular units are fixed and connected to space connectors and splicing plates by high-strength bolts to realize the splicing.

[0034]The modular unit includes structural components and decorative components. In a node, the structural components connected by each module unit include at least one vertical I-shaped frame column, two I-shaped frame beams perpendicular to the frame column, and one of the frame beams is perpendicular to the frame column And one end is fixedly connected to the web of the frame column, the other frame beam is perpendicular to the frame column and one end is fixedly connected to the flange of the frame column; the web of the frame beam is vertically arranged, and the flange is above and below the web sides. The decorative parts include partition walls, suspended ceilings, etc.; according to actual needs, the decorative parts are fixedly connected to the s...

Embodiment 2

[0063] The interior of the space connector A is equipped with energy-dissipating components, replacing the internal vertical reinforcement plate; the energy-dissipating components are selected from energy-dissipating plates or dampers. Among them, the surface of the energy dissipation board is provided with a diamond-shaped hole; the four edges of the energy dissipation board are respectively fixedly connected to the middle parts of the four boards connected and closed into a square frame in the space connector A.

[0064] All the other unmentioned parts are the same as in Embodiment 1.

Embodiment 3

[0066] When splicing three modular units (including two lower modular units and one upper modular unit), the upper modular unit is vertically spliced ​​with one of the lower modular units; the two lower modular units are spliced ​​horizontally.

[0067] When the upper module unit is spliced ​​with one of the lower module units; one frame column and two frame beams of the two are aligned vertically. The two space connectors A are respectively located between two pairs of frame beams in the same vertical direction in the upper and lower module units; the lower side flange of the frame beam of the upper module unit and the upper horizontal connecting plate of the space connector A are connected by high-strength bolts ;The upper wing plate of the frame beam of the lower module unit and the lower horizontal connecting plate of the space connector A are connected by high-strength bolts; the vertical connecting plate of the space connector A close to the frame column is fixedly connec...

Abstract

The invention discloses a modularized steel structure joint. Each structure part, used for connecting, of all module units at least comprises a vertical frame pillar and two frame beams, and the framebeams are perpendicular to and fixedly connected with the frame pillars; when splicing is carried out, splicing parts comprise module units and modules spliced by the module units, two splicing partsare simultaneously and fixedly connected to the same space connecting piece; each two frame beams and frame pillars of two module units vertically spliced are correspondingly be aligned in the vertical direction, and the frames pillars are simultaneously and fixedly connected to the same splicing plate; and when horizontal splicing is carried out, each frame beam and frame pillars of adjacent twomodule units in the same layer are correspondingly be aligned in the horizontal direction. The modularized steel structure joint belongs to the technical field of structural engineering. Under the premise that the joint mechanical property and the overall stability of the modularized steel structure joint are met, the high assembly rate and the high splicing efficiency can be realized; and the construction technology is simple, stress is reasonable, the realization of multi-high layer steel frame modularized construction is facilitated.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a modular steel structure node, which is suitable for the combination of space connectors and splicing plates connecting steel structure modular units. Background technique [0002] Modular building refers to the division of a traditional house into a single room as a building module unit, and the connection of each structural part of the module unit such as beams, columns, panels and decorative parts such as partition walls and ceilings is completed in the factory. The modular units are transported to the site to be stacked and connected to form a complete building. [0003] Modular building is an advanced stage in the development of building industrialization. It is a prefabricated structure with a high assembly rate. Compared with traditional steel structures, it has the advantages of green environmental protection, fast construction, flexible assemb...
