Description

A reusable modular keel connection node

technical field

The utility model relates to a novel modular membrane structure node in the field of civil engineering, in particular to a reusable modular keel connection node.

Background technique

The modular membrane structure system uses the modular keel as the basic frame, and the membrane structure is used for the roof and wall. It is a new structural system that integrates the advantages of modular buildings and membrane structures. It not only has the advantages of low energy consumption, low emission, short construction period, and high precision of modular buildings, but also greatly reduces the weight of the structure, facilitates transportation, and has better performance and visual effects. It is a reusable structural system.

The modular keel connection node of the modular membrane structure can firmly splice together various keel components produced in the factory, and ensure the coordinated force of each component in the keel, which is an important part of ensuring the safe and normal operation of the structure. Once the node is damaged, the connected rods will lose part or all of their bearing capacity, which may change the force transmission path, cause local damage, and seriously cause continuous damage to the entire structural system. Therefore, a reasonable node design should ensure that the node has sufficient bearing capacity and appropriate node stiffness to realize the transfer of internal force at the node. Traditional nodes are usually connected by welding or ordinary bolts. Considering that the keel of the modular membrane structure system can be made of steel or aluminum as the force-bearing member, and in order to facilitate installation and disassembly, it is not suitable to use welding as the connection method. Generally, the components of the bolted connection are usually vertical, but the components of the modular keel are at a certain angle, and some components themselves are also in the form of curves. Therefore, the traditional node form can no longer meet the requirements of modular membrane structure for architectural shape and function.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art and provide a reusable modular keel connection node, which uses bolts and a certain shape of the connection plate to fix various components in the keel together to ensure Loads are transferred smoothly between components.
