Unlockable mortise and tenon joint self-locking type column-column connecting joint

Abstract

The invention discloses an unlockable mortise and tenon joint self-locking type column-column connecting joint which is used for connecting an upper module unit and a lower module unit. The column-column connection mode can be applied to connection of corner module units, edge module units and middle module units. An inner box is welded to the upper end of a module column of the lower module unitthrough a connecting plate, and an outer box is welded to the lower end of the module column of the upper module unit. In the connecting process, tenons welded to an acting plates in the inner box canbe inserted into mortises formed in the outer box in advance under the thrust effect of a spring, and therefore column-column connection of the upper module unit and the lower module unit is completed. According to the self-locking type column-column connecting joint, reliable connection can be achieved only by inserting and attaching the upper module and the lower module at the corresponding positions, and extra connection operation is not needed. The unlockable mortise and tenon joint self-locking type column-column connecting joint can realize building industrialization, and has the advantages of accelerating the construction progress, saving energy, protecting the environment and the like.

Description

technical field [0001] The invention belongs to the technical field of architectural design, and more specifically relates to a mortise and tenon self-locking column-column connection node of a modular steel structure building. Background technique [0002] The reliable connection between the upper module unit and the lower module unit of the modular steel structure is very important for the mechanical performance of the whole modular steel structure building. The connection between traditional modular units generally adopts bolt connection or welding seam connection, but there are some problems in the connection between these two kinds of modular units. Firstly, on-site bolt connection and weld connection will increase the workload on site; secondly, these two joint forms require a certain amount of room for operation during the connection process, but for integrated modules that have completed interior decoration such as partition walls and floor slabs, , cannot provide t...

AI Technical Summary

Problems solved by technology

Firstly, on-site bolt connection and weld connection will increase the workload on site; secondly, these two joint forms require a certain amount of room for operation during the connection process, but for integrated modules that have completed interior decoration such as partition walls and floor slabs, , can not provide the operation space of bolted connection and welded seam connection

For example, the central column joints of the modular steel structure have the characteristics of "eight columns and sixteen beams", and the existence of multi-faceted partition walls and floor components makes the traditional bolt connection and weld connection basically impossible.

On the other hand, it is difficult to ensure that the traditional bolted connection and welded seam connection can be dismantled without destroying the integrity of the modular unit itself.
